Step-by-step explanation:

23400 - 1700 = 21700

Walter's salary last year can be found by subtracting the increase from his current salary. After calculating, we find that Walter's salary last year was $21,700.

To calculate Walter's salary last year, we need to subtract the amount his salary increased this year from his current salary. Walter's current salary is $23,400, and it has increased by $1,700 from last year. Thus, his salary last year was:

$23,400 (current salary) - $1,700 (increase) = $21,700

Therefore, Walter's salary last year was $21,700.

Answer:

8189.11

Step-by-step explanation:

If 8900 is 100% and we need to find 15%  we would multiply 8900 and 15 then divide by 100 and that equal 1335 so we would then subtract 1335 from 8900 because it is 15% off, which equals 7565, so now 7565 is 100% and we need to add the 8.25% tax, so we multiply 7565 and 8.25 then divide by 100 which equals 625.11 then we add 7565 and 625.11 which equals 8189.11

The sale price of the car is $8,188.36.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed.

We have,

A car originally priced at $8,900 is on sale at 15% off.

If the sales tax rate is 8.25%.

So, Discount

= 15% of $8,900

= 0.15 x $8,900

= $1,335

Now, Price after discount

= $8,900 - $1,335

= $7,565

and, Sales tax

= 8.25% of $7,565

= 0.0825 x $7,565

= $623.36

So, Sale price of the car

= $7,565 + $623.36

= $8,188.36

Therefore, the sale price of the car is $8,188.36.

Answer:

Total pay for the week is $924.

Step-by-step explanation:

The per hour rate of weekdays from Monday to Friday =  $15.40

The rate for Saturday = One and Half ( $15.40)

Now,  [tex]1\frac{1}{2}  \times (15.40)  = \frac{3}{2} (15.40) = 23.1[/tex]

So, the per hourly rate for work on Saturday  = $23.1

The rate for Sunday  = 2 x ( $15.40)  = $30.80

So, the per hourly rate for work on Sunday  = $30.80

Now, total hours worked in weekday = 38

So, the rate of 38 hours = 38 x ( Per hour rate) = 38 x ($15.40)  

                                        = $585.2

Now, total hours worked on Saturday  = 8

So, the rate of 8 hours = 8 x ( Per hour rate) = 8 x ($23.1)    = $184.8

Now, total hours worked on Sunday  = 5

So, the rate of 5 hours = 5 x ( Per hour rate) = 5 x ($30.80)    = $154

Hence the total pay = Payment of ( weekday  + Saturday +Sunday)

= $585.2 +  $184.8 +  $154  =  $924

Hence, total pay for the week is $924.

The new copier can create 2000 copies in 20 minutes.

Step-by-step explanation:

Given,

It takes 60 minutes to make 2000 copies by old printer and 15 minutes to made x number of copies, therefore, using proportion

[tex]60:2000::15:x[/tex]

Product of mean = Product of extreme

[tex]2000*15=60*x\\30000=60x\\60x=30000[/tex]

Dividing both sides by 60

[tex]\frac{60x}{60}=\frac{30000}{60}\\x=500[/tex]

As the new copier is working with old copier, therefore,

Copies made by new printer = 2000 - 500 = 1500

New copier can make 1500 copies in 15 minutes and 2000 copies in x minutes, using proportion

[tex]1500:15::2000:x\\1500*x=15*2000\\1500x=30000[/tex]

Dividing both sides by 1500;

[tex]\frac{1500x}{1500}=\frac{30000}{1500}\\x=20[/tex]

Answer:

The Value of x is 40.

Step-by-step explanation:

Given:

∠SRT ≅ ∠STR

∠SRT = 20

m∠SRT = 4x

To find: Value of x

Solution:

From the given data,

m ∠SRT = 20

Also ∠SRT ≅ ∠STR

Hence from congruence and equality property we can say that;

m∠STR= 20

m∠STU= 4x

Now by straight angle property which states that sum of two angles which are created by a straight line is always 180.

Hence,

∠STR +∠STU =180

Now Substituting the given values we get;

[tex]20+4x=180\\4x=180-20\\4x=160\\\\x=\frac{160}{4} =40[/tex]

Hence m∠STU = 4x =4 ×40 = 160°

Hence the value of x = 40.

Answer:

y + 5 = 3(x + 1) → point-slope form

y = 3x - 2 → slope-intercept form

3x - y = 2 → standard form

Step-by-step explanation:

The point-slope form of an equation of a line:

y - y₁ = m(x - x₁)

m - a slope

(x₁, y₁) - a point on a line

We have

m = 3, (-1, -5) → x₁ = -1, y₁ = -5

Substitute:

y - (-5) = 3(x - (-1))

y + 5 = 3(x + 1) → point-slope form

convert to the slope-intercept form y = mx + b:

y + 5 = 3(x + 1)      use the distributive property: a(b + c) = ab + ac

y + 5 = 3x + 3     subtract 5 from both sides

y = 3x - 2 → slope-intercept form

convert to the standard form Ax + By = C:

y = 3x - 2            subtract 3x from both sides

-3x + y = -2         change the signs

3x - y = 2 → standard form

Answer:

The area is 12.56, and the circumference is 12.56.

Step-by-step explanation:

For the area,

We need to use the formula A=3.14*radius*radius

So we plug it in, and we get 3.14*2*2, which is 12.56 centimeters squared.

For circumference, we need to do,

C = 3.14*diameter

To find the diameter we need to do 2 (radius) x 2 which is 4

Plugging it in that would be 3.14 * 4 which is 12.56

So, in this case, the area is 12.56, and the circumference is also 12.56.

The area of a circle with a radius of 2 cm is 12.56 cm², and the circumference is 12.56 cm, using 3.14 for pi.

To find the area and circumference of a circle with a radius of 2 cm, we can use the formulas A = πr² for the area and C = 2πr for the circumference, where π (pi) is approximately 3.14.

Area of the Circle

The area of the circle is calculated using the formula A = πr². Plugging in the radius:

A = 3.14 × (2 cm)²

A = 3.14 × 4 cm²

A = 12.56 cm²

Circumference of the Circle

The circumference of the circle is calculated using the formula C = 2πr. Plugging in the radius:

C = 2 × 3.14 × 2 cm

C = 12.56 cm

Step-by-step explanation:

The first thing we have to do is to find the lowest number that can be squared to 74. 1,4,9,16,25,36,49,64,81,100.

As we see, 64 is the lowest closest number to 74 and the square root of 64 is 8. So right now, is 8<square root of 74<___.

Now, we have to find the highest number closest to 74. As we look back at our square roots, 81 is the closest number to 74 in the square roots and the square root is 9 and voila. 8<sqrt74<9

The inequality is -

8 < √74  < 9.

We have the following inequality -

_____<√74 <____.

We have to fill in the blanks with two consecutive integers to complete the above inequality.

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

According to the question -

Let A = √74

Then -   A² = 74

Answer:

Multiply the length by the width to find the area in square metres and then multiply that figure by 0.03 Kg to find out how much seed you'll need.

Step-by-step explanation:

Answer:

20 bags of seed is needed for the new lawn

Step-by-step explanation:

To answer this question, first find the area of the lawn and divide the area calculated by the number of square feet per bag of seed.

A  lawn is assumed to have a rectangular shape, the area (A) of the lawn  therefore is

               A = L x W

Where:    A = Area of lawn

                L = Length of lawn

               W =  Width of lawn

                A = L x W

                 L = ?

                W = 60 ft

To find the length, use the formula for the perimeter of a rectangle since the lawn is assumed to a rectangular shape

Perimeter (P) = 2(L+W)

                  P = 300 ft

            300  = 2(L + 60) ft

            300  = 2L + 120

Subtract 120 from both sides

   300 - 120  = 2L + 120 - 120

              180 = 2L

Divide both sides of the equation by the coefficient of L which is 2

         180/2 = 2L/2

             90 = L

              L  =  90 ft

That is, the length of the lawn is 90 ft

To calculate the area of the lawn

              A  = L x W

              L   =  90 ft

              W  = 60 ft

               A  = 90 ft x 60 ft

               A  = 5400 square feet

This means that the area of the lawn is 5,400 square feet

To get the number of bags of seed that will cover the lawn, divide the area of the lawn by the number square feet that a bag will cover.

Number of bags of seed  = Total Area of lawn/Number square feet per bag.

Total Area                          = 5400 square feet

Number square

feet per bag                      = 270

Number of bags               = 5400/270

                                          = 20 bags of grass seed

20 bags of seed is needed for the new lawn

Answer:812/1000

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Total Price of all 3 items - $34.19

35 > 34.19

Yes, Kiera will have enough to purchase all three items.

No, $35 will not be enough to purchase all three items.

To determine if $35 is enough to purchase all three items, we need to calculate the total cost of the items and compare it to the amount of money Kiera has.

The cost of each item is as follows:

- Mixing bowl: $14.95

- Spatula: $8.49

- Measuring cups: $10.75

Now, let's add up the costs of these items to find the total cost:

Total cost = Cost of mixing bowl + Cost of spatula + Cost of measuring cups

Total cost = $14.95 + $8.49 + $10.75

To make the calculation easier, we can round each price to the nearest whole number:

- Mixing bowl: $14.95 ≈ $15.00

- Spatula: $8.49 ≈ $8.50

- Measuring cups: $10.75 ≈ $10.75 (already a whole number)

Now, let's calculate the total cost with these rounded numbers:

Total cost ≈ $15.00 + $8.50 + $10.75

Total cost ≈ $34.25

However, even with rounding, the total cost is $34.25, which is still less than $35. Therefore, we need to calculate the exact total cost without rounding:

Total cost = $14.95 + $8.49 + $10.75

Total cost = $34.19

Since the total cost of $34.19 is less than $35, it appears that Kiera has enough money to purchase all three items. However, we must also consider sales tax, which is not included in the given prices. Sales tax rates vary by location, but let's assume a standard rate of 7%.

To calculate the total cost including sales tax:

Total cost with tax = Total cost before tax + (Total cost before tax × Sales tax rate)

Total cost with tax = $34.19 + ($34.19 × 0.07)

Total cost with tax = $34.19 + $2.3933

Total cost with tax ≈ $34.19 + $2.40 (rounded to the nearest cent)

Total cost with tax ≈ $36.59

After including the sales tax, the total cost is approximately $36.59, which is more than the $35 Kiera has. Therefore, $35 will not be enough to purchase all three items once sales tax is included.

Answer:

Step-by-step explanation:

        First alloy contains 34% copper and the second alloy contains 48% alloy.

We wish to make 46 pounds of a third alloy containing 37% copper.

       Let the weight of first alloy used be [tex]x[/tex] in pounds and the weight of second alloy used be [tex]y[/tex] in pounds.

       Total weight = [tex]46\text{ }pounds=x+y[/tex]        [tex]-(i)[/tex]

      Total weight of copper = [tex]37\%\text{ of 46 pounds = }34\%\text{ of }x\text{ pounds + }48\%\text{ of }y\text{ pounds }[/tex]

       [tex]\dfrac{37\times 46}{100}=\dfrac{34x}{100}+\dfrac{48y}{100}\\\\ 34x+48y=1702[/tex]        [tex]-(ii)[/tex]

       Subtracting 34 times first equation from second equation,

[tex]34x+48y-34x-34y=1702-34\times46\\14y=138\\y=9.857\text{ }pounds \\x=36.143\text{ }pounds[/tex]

∴ 36.14 pounds of first alloy and 9.86 pounds of second alloy were used.

Final answer:

The metallurgist must use around 36.14 pounds of the 34% copper alloy and approximately 9.86 pounds of the 48% copper alloy to make 46 pounds of a 37% copper alloy.

Explanation:

To solve the problem involving an alloy containing copper, we can use a system of equations based on the percentages provided and the total weight required for the new alloy.

Let's denote x as the number of pounds of the 34% copper alloy, and y as the number of pounds of the 48% copper alloy. We are aiming to create 46 pounds of a 37% copper alloy.

The first equation represents the total weight of the mixture:

x + y = 46

The second equation represents the total amount of copper in the new alloy:

0.34x + 0.48y = 0.37 * 46

Solving this system of equations, we get:

Multiply the second equation by 100 to remove decimals: 34x + 48y = 37 * 46

Substitute y from the first equation into the second: 34x + 48(46 - x) = 37 * 46

Simplify and solve for x: 34x + 2208 - 48x = 1702

This yields -14x = -506, so x = 506 / 14 = 36.14

Using x to solve for y gives us y = 46 - 36.14 = 9.86

Therefore, the metallurgist must use around 36.14 pounds of the 34% copper alloy and approximately 9.86 pounds of the 48% copper alloy to make 46 pounds of the third alloy containing 37% copper.

The amount deposited in CD is $660

Given that , To save for the purchase of a new car, a deposit was made into an account that earns 8% annual simple interest.  

Let the amount deposited in new car be $ n

Another deposit, $1700 less than the first deposit, was placed in a certificate of deposit (CD) earning 12% annual simple interest.  

Then, amount deposited in CD will be $ (n – 1700)

The total interest earned on both accounts for 1 year was $676

The simple interest is given as:

[tex]\text { Simple interest }=\frac{\text { principal } \times \text {rate} \times \text {time}}{100}[/tex]

Simple interest for purchase of new car:

[tex]\text { S. } \mathrm{I}=\frac{n \times 8 \times 1}{100}=\frac{8 n}{100}[/tex]

Simple interest for CD:

[tex]\text { S.I } =\frac{(n-1700) \times 12 \times 1}{100}=\frac{12(n-1700)}{100}[/tex]

Now, given that S.I for new car + S.I for CD = 676

[tex]\begin{array}{l}{\frac{8 n}{100}+\frac{12(n-1700)}{100}=676} \\\\ {\frac{8 n+12 n-12 \times 1700}{100}=676}\end{array}[/tex]

20n = 67600 – 20400

n = 2360

So money deposited in CD = n - 1700 = 2360 – 1700 = 660

Hence, the CD deposit amount is $660

To find the amount deposited in the CD, set up an equation using the given information. Solve for x to find the amount of the first deposit. Subtract $1700 from the first deposit to find the amount deposited in the CD.

To find the amount of money deposited in the CD, we can set up an equation using the given information.

Let the amount of the first deposit be x.

The second deposit is $1700 less than the first deposit, so it is x - $1700.

Using the formula for simple interest, the interest earned on the first deposit is x * 0.08.

The interest earned on the second deposit is (x - $1700) * 0.12.

According to the given information, the total interest earned is $676. Therefore, we can set up the equation: x * 0.08 + (x - $1700) * 0.12 = $676.

Simplifying and solving for x:

0.08x + 0.12x - $204 = $676

0.20x - $204 = $676

0.20x = $880

x = $4400

Therefore, the amount of money deposited in the CD is $4400 - $1700 = $2700.
