Answer:

30 yellow straws and 45 red straws

30:45

Step-by-step explanation:

Make a ratio:

2:3, 2 being the yellow straw and 3 being the red straws

They are now asking how many red if there are 30 yellow straws

2:3 = 30:x

You could either cross multiply or simply do 30 ÷ 2 = 15 then 15 × 3 = 45. Your answer is 45

Cross multiplying

2x = 90

90 ÷ 2 = 45

To find the total price including tax after a meal at a restaurant, convert the tax rate to a decimal, then multiply it by the total cost and add the result to the original total cost.

First, find the amount of sales tax. To do this, convert the percent to a decimal by dividing by 100: 8.25% = 0.0825.

Then multiply the total cost by the decimal tax rate to get the tax amount. In this case, $95 * 0.0825 = $7.8375.

Next, add the tax amount to the original total cost to find the total price: $95 (original cost) + $7.8375 (tax) = $102.8375.

Therefore, the total price, including tax, for Shirley and her family's meal last night was $102.84.

Answer:

2.5%

Step-by-step explanation:

The price increased from 2 to 2.05. So the increase was:

2.05 - 2 = 0.05 dollars

Now, to find percentage increase, we use the formula below:

[tex]\frac{New-Old}{Old}*100[/tex]

Where

New is the latest price (here it is the increased price of 2.05)

Old is the previous price (here it is the less price of 2.00)

Now, we substitute and find:

[tex]\frac{2.05-2.00}{2.00}*100=2.5[/tex]

So the price increase was 2.5%

Answer:

c = 36

Step-by-step explanation:

Given

a² + 12a + c

To complete the square

add ( half the coefficient of the a- term )² to a² + 12a

a² + 2(6)a + 6²

= (a + 6)² + 36

Hence the value of c = 36

Final answer:

Three half squared is (3/2)², which equals 9/4 when you square the numerator (3² = 9) and the denominator (2² = 4) separately.

Explanation:

The expression 'three half squared' refers to the quantity (3/2) squared. To square a fraction, you square the numerator and the denominator separately. Therefore, (3/2) squared is (3 squared) over (2 squared), which is 9 over 4. Since there are no further simplifications to make, 9/4 is the final answer as a fraction.

To understand this conceptually, think about the process of squaring as finding the area of a square with side lengths of the original number. So, if the side length of a square is 3/2, the area (which represents the square of the number) will be 9/4 square units.

Final answer:

To determine what three-half squared is as a fraction, you simply square the numerator and denominator separately, arriving at the fraction 9/4.

Explanation:

Calculating Three-Half Squared as a Fraction

To find what three half squared is as a fraction, you square both the numerator and the denominator of the fraction 3/2. When you square the numerator (3), you get 9, and when you square the denominator (2), you get 4. Therefore, the answer to three half squared is 9/4, as we have calculated (3/2)² = (3²)/(2²) = 9/4.

This calculation is similar to understanding that if you start with half of a pie and you multiply this amount by itself, you are essentially getting a fraction of the original whole. In our example, by squaring half, we get a quarter, thereby following the intuitive sense of fractions.

Answer:

The two numbers are 12 , 10

Step-by-step explanation:

Given as :

The least common multiple of two numbers = LCM = 60

The ratio of the greater number to lesser number = 6 : 5

let the greater number = 6 x

And The smaller number = 5 x

∵ The LCM of numbers = 60

So, 6 × 5 × x = 60

Or,  30 × x = 60

∴  x = [tex]\frac{60}{30}[/tex]

I.e x = 2

So The greater number = 6 x = 6 × 2 = 12

And  The smaller number = 5 x = 5 × 2 = 10

Hence The two numbers are 12 , 10 Answer

Answer:

$2 per ride

Step-by-step explanation:

$32-$20=$12

McKenna rode 6 rides so $12 divided by 6 rides is $2 for every ride

Final answer:

The equation to find the price for each ride McKenna paid at the carnival is $32 - 6P = $20. Solving for P gives us P = $2, so each ride costs $2.

Explanation:

To find the price for each ride that McKenna paid at the carnival, we need to set up an equation based on the information given. McKenna started with $32 and ended with $20 after riding 6 rides. The amount spent on rides is the difference between the starting amount and the remaining amount.

The equation will be:

Initial amount - (Price per ride × Number of rides) = Remaining amount

$32 - (Price per ride × 6) = $20

Let's denote the price for each ride as P. So the equation becomes:

$32 - 6P = $20

To solve for P, we rearrange the equation:

6P = $32 - $20

6P = $12

P = $12 / 6

P = $2

Hence, the price for each ride is $2.

Part 4) we have

[tex]g=x-c+y[/tex]

solve for x

That means---> Isolate the variable x

Subtract y both sides

[tex]g-y=x-c+y-y[/tex]

[tex]g-y=x-c[/tex]

Adds c both sides

[tex]g-y+c=x-c+c[/tex]

[tex]g-y+c=x[/tex]

rewrite

[tex]x=g-y+c[/tex]

Part 5) we have

[tex]xm=x+z[/tex]

solve for x

That means---> Isolate the variable x

Subtract x both sides

[tex]xm-x=x+z-x[/tex]

[tex]xm-x=z[/tex]

Factor x left side

[tex]x(m-1)=z[/tex]

Divide by (m-1) both sides

[tex]\frac{x(m-1)}{m-1}=\frac{z}{m-1}[/tex]

[tex]x=\frac{z}{m-1}[/tex]

Part 6) we have

[tex]g=ca-b[/tex]

solve for a

That means---> Isolate the variable a

Adds b both sides

[tex]g+b=ca-b+b[/tex]

[tex]g+b=ca[/tex]

Divide by 2 both sides

[tex]\frac{P-2L}{2}=\frac{2W}{2}[/tex]

simplify

[tex]W=\frac{P-2L}{2}[/tex]

[tex]W=\frac{P}{2}-L[/tex]

Part 9) we have

[tex]Q=\frac{c+d}{2}[/tex]

solve for d

That means---> Isolate the variable d

Multiply by 2  both sides

Factor the variable a in the right side

[tex]Q=a(3+5c)[/tex]

Divide by (3+5c) both sides

[tex]\frac{Q}{3+5c}=\frac{a(3+5c)}{3+5c}[/tex]

simplify

[tex]a=\frac{Q}{3+5c}[/tex]

Part 11) we have

[tex]I=\frac{PN}{RN+A}[/tex]

solve for N

That means---> Isolate the variable N

Multiply in cross

[tex]I(RN+A)=PN[/tex]

[tex]IRN+AI=PN[/tex]

subtract PN both sides

[tex]IRN+AI-PN=PN-PN[/tex]

[tex]IRN+AI-PN=0[/tex]

Divide by (IR-P) both sides

[tex]\frac{N(IR-P)}{IR-P}=-\frac{A}{IR-P}[/tex]

simplify

[tex]N=-\frac{A}{IR-P}[/tex]

[tex]N=\frac{A}{P-IR}[/tex]

Part 12) we have

[tex]P=a+b+c[/tex]

solve for b

That means---> Isolate the variable b

subtract (a+c) both sides

The point estimate for the proportion of homeowners in the given sample is 75%, calculated by dividing the number of homeowners (24) by the total number surveyed (32).

Explanation:

To obtain a point estimate of the proportion of homeowners from the given sample, we would calculate the proportion of those who did not rent, since owning and renting are the only two options provided. Out of 32 people, 8 said they rented, which means 32 - 8 = 24 owned their home. The point estimate for the proportion of homeowners is then given by the number of homeowners divided by the total number of people surveyed:

Point estimate for homeowners = (Number of homeowners) / (Total number surveyed) = 24 / 32 = 0.75 or 75%

This mean 75% of the surveyed individuals are estimated to be homeowners.

Final answer:

To find the alcohol percentage in the 4:1 ratio, we use the information from the 3:2 ratio. For every 3 parts alcohol, there are 2 parts water. When mixed at a ratio of 4:1, the alcohol percentage is 24%.

Explanation:

To determine the alcohol percentage of the solution when mixed at a ratio of 4:1, we can use the information given in the question. When mixed at a ratio of 3:2, the solution contains 18% alcohol. This means that for every 3 parts alcohol, there are 2 parts water. We can use this information to find the alcohol percentage for the 4:1 ratio.

Let's say we have 4 mL of alcohol and 1 mL of water. The total volume is 4+1 = 5 mL. In the 3:2 ratio, the alcohol percentage is 18%. So, for 3 mL of alcohol, the total volume is 3+2 = 5 mL. Therefore, the alcohol percentage for the 4:1 ratio is (18/3) * 4 = 24%.

Answer:

$75.26

Step-by-step explanation:

base cost = $49.95

total mile cost = 1.19*18 =$21.42

gas cost = $3.89

total cost =$(49.95 +21.42+3.89)=$75.26

The expression to represent total cost of the trip is $49.95 + $1.19m + (m/18)($3.89).

Given that, the rental has a base cost of 49.95, plus an additional cost of 1.19 per mile driven.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

If we let m = total distance, then we can set up an equation to find the total cost.

The additional cost for distance would be $1.19m

The cost for gas would be (m/18)($3.89)

So the total cost of the trip could be represented by $49.95 + $1.19m + (m/18)($3.89).

Therefore, the expression to represent total cost of the trip is $49.95 + $1.19m + (m/18)($3.89).

$0.10x + $0.25y = $0.80

The equation in standard form that represents the situation is 10x + 25y = 80.

To represent the situation in terms of the number of dimes and quarters, we can use the equation 0.10x + 0.25y = 0.80. This equation states that the value of the dimes (0.10x) plus the value of the quarters (0.25y) equals $0.80. Rearranging the equation to standard form, we have:

0.10x + 0.25y = 0.80

10x + 25y = 80

So, the equation in standard form that represents the situation is 10x + 25y = 80.
