Answer: 32 pages per hour
Step-by-step explanation:
First find out the total number of hours she took to read the book:
= 3/4 + 1 ³/₄
= 3/4 + 7/4
= 10/4 hours
There were 80 pages in the book. her average per hour was:
= Pages / time
= 80 ÷ 10/4
= 80 * 4/10
= 32 pages per hour
Note: If you are to divide by a fraction, multiply by its inverse instead.
Question 4 The 6th grade class is raising money for a camping trip to the mountains. So far they have raised $900, which is 60% of the total cost. How much money does the total trip cost?
Answer:
1500
Step-by-step explanation:
Total cost would be 60%+40%
Since we have 60% amount already
0.60* total cost=900
total cost=90000/60
=1500

Answer:Hi B)
Step-by-step explanation:
Please answer correct its not 9 units
26x + 13y = 39
.
Rearrange this equation so it is in the form y = mx + b
After you have rearranged the equation, identify the slope and the y-intercept.
If x = 6, what should y =? Show all necessary work and steps. Round any decimals to
1 place as necessary.
If y = -1, what should x =? Show all necessary work and steps. Round any decimals
to 1 place as necessary.
Answer:
Rearrange: y=-2x+3
if x=6 then y = -9
if y=-1 then x = 2
Step-by-step explanation:
Algebra
to rearrange here are the steps
26x+13y=39
First move x to other side by subtraction
13y= -26x+39
to get y as just y divide everything by 13. Since 13/13=1 or 13y/13= y
y=-2x+3

Combine the like terms to create an equivalent expression:
-k+3k
Answer:
=ykvnn
Step-by-step explanation:
Answer: 2k
Step-by-step explanation:
Like terms are terms that have the same variables and powers.
k is the same variable so you would take away k (or 1k we just don’t write 1k in algebra) from 3k=2k

It takes a street sweeper 27 minutes to travel 3 miles. If the street sweeper travels at the same speed, how many miles will the street sweeper travel in 45 minutes?
Answer:
x=5 miles
Step-by-step explanation:
first you have to get his constant speed or his rate
rate = time / distance
so in this case 27/3 which equals 9,
1 mile = 9 minutes
then, you would set up your equation
9 minutes = 1 mile
45 minutes = x miles
cross multiply , 45 * 1= 45 , then divide by 9
x = 5 miles

Jasper Wrote a formula for the area of triangle RST in terms of only the sides and angles. His steps are shown.
Step 1: A =
1: A = 1/2 hs
Step 2: sin(R) = h/r
h = rsin(R)
Step 3: A = 1/2(r)(s)sin(R)
Identify the error in Jasper's work, then replace one term in his equation to write a correct equation for the area.
A= 1/2rs sin(R)
Answer:
replace r with t
Step-by-step explanation:

The correct equation for the area of the triangle is A= 1/2st sin(R).
What is the area of triangle?The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to the base times the height divided by half.
Area = (1/2)×Base×Height
Correct calculation for the area of the triangle.
Step 1: Use formula to calculate area.A = (1/2)×Base×Height
Base = s
height = h
A = 1/2 hs
Step 2: Use sine function to get the value of height h.Sine (R) = Base/Hypotenuses
sin(R) = h/t
h = tsin(R)
Step 3: Substitute the value of h in area A.A = 1/2(t)(s)sin(R)
Therefore, the correct area of the triangle is A = 1/2(t)(s)sin(R).

A four-sided polygon has sides that measure 1 cm, 5cm, and 7 cm. (Forth side not given). What is the perimeter?
Answer:
(13+x)cm
Step-by-step explanation:
Given data
Length of sides
1cm, 5cm, 7cm
Since the shape is four-sided and the fourth side is not given, let the fourth side be x
so
The perimeter of the polygon is
P= 1+5+7+x
P= 13+x
Hence the perimeter of the polygon is
P= (13+x)cm

The first figure is dilated to form the second figure.
Which statement is true?
The scale factor is 0.4.
The scale factor is 0.9.
The scale factor is 2.1.
The scale factor is 2.5.
Answer:
The scale factor is 2.5
Step-by-step explanation:
took k-12 test
When a shape is dilated, the size of the shape changes
The true statement is (d) The scale factor is 2.5.
What is dilation?Dilation involves changing the size of a shape or figure
How to determine the scale factorIn figure A, we have:
Length = 0.6
In figure B, we have:
Length =1.5
The scale factor is then calculated as:
[tex]k = \frac{1.5}{0.6}[/tex]
Divide
[tex]k = 2.5[/tex]
Hence, the true statement is (d) The scale factor is 2.5.

Given the point and its image, determine the scale factor. B(2,5) B'(1,2.5) 0 -1/2 02 0-2 O 1/2
Given:
The point is B(2,5) and its image is B'(1,2.5).
To find:
The scale factor.
Solution:
If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as
[tex]k=\dfrac{\text{x-coordinate of the point on image}}{\text{x-coordinate of the corresponding point on the original figure}}[/tex]
x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is
[tex]k=\dfrac{1}{2}[/tex]
Therefore, the scale factor is [tex]\dfrac{1}{2}[/tex] and the correct option is D.
