Answer:

Distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh

Explanation:

Distance traveled by a body = Velocity of the body * Time taken by the body

Here velocity of Sierra =  2x miles per hour

Time taken by Sierra = h hours.

Distance traveled by Sierra = 2x * h = 2xh

So distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh

Answer:

Value of house in 2017  = 231525$

Explanation:

 At the start of 2014 worth of Lucy's house = 200000$

 Rate of increase of the value of the house = 5% = 0.05

 Value of house in 2015 = 200000+0.05*200000 = 210000$

 Value of house in 2016 = 210000+0.05*210000 = 220500$

 Value of house in 2017 = 220500+0.05*220500 = 231525$

 Number of years in between 2014 and 2017 = 2017 - 2014 = 3 years.

 Value of house in 2017 [tex]=200000*1.05^3=231525$[/tex]

A sidewalk is built 12 bricks wide by laying each brick side by side.

The size of each brick measures [tex]3\frac{3}{8}[/tex]

Convert the mixed fraction into improper fraction

[tex]3\frac{3}{8}= \frac{27}{8}[/tex]

The width of each brick is [tex]\frac{27}{8}[/tex]

To built side walk, 12 bricks are used

To find the width of side walk , we multiply the number of bricks with the width of each brick

[tex]12 * \frac{27}{8}[/tex]

We can cancel out 12  and 8

[tex]3 * \frac{27}{2}[/tex]

"Less than" means subtraction

The order they appear in tells me to subtract 9 from N.

n - 9

Answer: c - 9

Step-by-step explanation: i did the quiz and this is the right answer

Problem 1

Plug in x = 0 and solve for y to get the y intercept

6x+12y = 60

6(0)+12y = 60

12y = 60

12y/12 = 60/12 ... divide both sides by 12

y = 5

Answer: A) 5

======================================

Problem 2

Use the slope formula.

The two points are (x,1, y1) = (1, -1) and (x2, y2) = (-2, 8)

m = (y2-y1)/(x2-x1)

m = (8-(-1))/(-2-1)

m = (8+1)/(-2-1)

m = 9/(-3)

m = -3

Answer: A) -3

Step-by-step explanation:

From the given figure, it can be seen that TG and LI are the chords of the circle with center O such that TG=LI=10.4 which means that TG is congruent to LI.

Also, OE and OH gives the shortest distance(perpendicular) of the chord LI and TG respectively from center of circle O.

And, We know that "the congruent chords are equidistant from the center of a circle."

Therefore, we can conclude that, OH is congruent to OE.

Hence, option (A) is correct.

From the figure we can conclude that OH is congruent to OE.

The fourth graph represents the function.

We have to rewrite the given function into the standard form of a parabola.

A parabola is a U-shaped plane curve that is symmetrical about its vertex.

The standard form of a parabola is given by:

y = (x-h)²+k

Where (h,k) is the vertex of the parabola.

f(x) = x²+2x-1

We can rewrite this as:

f(x) = x²+2x+1-2

f(x) =( x+1)²-2

Now compare this with the given graphs. The only graph that has its vertex at (-1,-2) is the fourth graph.

We have found the graph that represents the function f(x) = x²+2x-1 to be the fourth graph.

If the two equations intersect at [tex](50,60)[/tex] then this point must satisfy the two equations.

[tex]3x+2y=270---(1)[/tex]

We substitute  [tex](50,60)[/tex]  in to erquation (1)

Your answer is A.

Whole numbers are a subset of integers, which in turn are a subset of rational numbers.

So, every whole number is an integer, and every integer is a rational number.

So, it is possible for a rational number not to be an integer. Think of any decimal number: 1.356 is a rational number, but it's not an integer.

On the other hand, if a number is not an integer, it can't be a whole number, because all whole numbers are integers.

the longest piece will be associated with 8 parts of the ratio.

divide 144 by 8 to find 1 part of the ration then multiply this value by 6 and 4 for the remaining parts of the ratio

[tex]\frac{144}{8}[/tex] = 18 cm ← 1 part

6 parts = 6 × 18 = 108 cm

4 parts = 4 × 18 = 72 cm

length = 144 + 108 + 72 = 324 cm = 3.24m

Answer: 324 cm

Step-by-step explanation:

  6 :   8 :   4

x18 x18  x18

108  144   72

108 + 144 + 72 = 324

5 units right: x + 5

1 unit up: y + 1

(x, y) → (x + 5, y + 1)

Answer:

6 appointments are cancelled per day

Step-by-step explanation:

Question says  4 out of 24 appointments are cancelled.

It means out of 1 appointment , the cancelled appointments = [tex]\frac{4}{24}[/tex]

=[tex]\frac{1}{6}[/tex]

Now the questions says each day there are 36 appointments

And we have to find how many appointments got cancelled each day,

It means we have to find how many appointments got cancelled out of 36 appointments each day

So we multiply 36  by [tex]\frac{1}{6}[/tex]

=[tex]36 * \frac{1}{6}[/tex]

= 6

Hence , 6 appointments got cancelled each day.

Jasmine has 6 appointments cancelled per day, determined by scaling the given cancellation ratio (4 out of every 24) to match the number of daily appointments she books (36).

To answer this question, we first need to understand the rate at which appointments are cancelled. The problem states that 4 out of every 24 appointments are cancelled. To find out how many appointments are cancelled each day, we use this ratio and apply it to the 36 appointments that Jasmine books each day.

First, we need to scale the ratio to match Jasmine's daily bookings. To do this, we multiply the numerator and denominator of the ratio by 36/24, which is 1.5. This gives us a new ratio of 6 cancellations for every 36 appointments.

So, each day, out of the 36 appointments that Jasmine books, 6 appointments are cancelled.

13,501 rounded to the nearest ten thousand is 14,000. This is because if you look at the 3, the number next to it is 5, causing it to round up. Numbers 0-4 are rounded down, and numbers 5-9 are rounded up.

Answer:

10,000

Step-by-step explanation:

When we round a number to the nearest ten thousand we check the digit at the thousand place,

If the digit ≥ 5,

The number is rounded to next ten thousand,

If the digit < 5,

The number is rounded to previous ten thousand.

Here, the given number,

13,501,

Digit at thousand place = 3 ( < 5 )

Thus, 13,501 ≈ 10,000 ( nearest ten thousand )

Answer:

Measure of ∠P = 60°

Step-by-step explanation:

Consider triangle PMO.

Since PM is perpendicular to MO , hence m∠PMO = 90°

Also given that m∠MOP = m∠2 = 30°

And since sum of three angles of a triangle is 180°

⇒ m∠PMO + m∠MOP + m∠MPO = 180°

⇒m∠MPO = 180° - (m∠PMO + m∠MOP) = 180° - ( 90 + 30 ) = 60°

Hence m∠MPO that is m∠P is 60°

Answer:

m 2 = 30°, m P = 60

The correct choice is 60

The selling price of the jacket, after the store increases its purchasing price by 80%, is $36.

The subject of this question is mathematics, specifically a practical application of percentages. The store buys the jacket for $20 and then increases the sale price by 80% for its customers. First, to calculate the 80% of the cost price, you multiply 20 (the cost price) by 0.80 (the percentage increase represented as a decimal). This results in $16. The selling price is then calculated by adding this calculated value to the original cost price which gives us $20 + $16 = $36. So, the store sells the jacket for $36.

Final answer:

To solve the word problem, subtract 3 from 8 to find the number of Dalmatians Sarah has, then add that number to Joe's 8 Dalmatians to determine the total number of Dalmatians they have together, which is 13.

Explanation:

To solve the word problem presented, we need to perform two primary operations: subtraction and addition. Joe has 8 Dalmatians, and Sarah has 3 fewer Dalmatians than Joe.

First, we determine how many Dalmatians Sarah has by subtracting 3 from 8. Once we know how many Dalmatians Sarah has, we add that number to Joe's 8 Dalmatians to find out the total number they have together.

Step 1: Calculate the number of Dalmatians Sarah has.
Sarah's Dalmatians = Joe's Dalmatians - 3
Sarah's Dalmatians = 8 - 3
Sarah's Dalmatians = 5

Step 2: Calculate the total number of Dalmatians they have together.
Total Dalmatians = Joe's Dalmatians + Sarah's Dalmatians
Total Dalmatians = 8 + 5
Total Dalmatians = 13

Therefore, Joe and Sarah have a total of 13 Dalmatians together.
