Answer:
$56.
Step-by-step explanation:
Given : $23.45+$3.98+$16.66+$12.08
To Find : Estimate to the nearest dollar , the total cost
Solution:
Total cost = $23.45+$3.98+$16.66+$12.08
Total cost = $56.17
So, The total cost = 56.17
Find the place value you want to round off and look to the digit just to the right of it.
If that digit is less than 5, do not change the "rounding digit"
If that digit is greater than or equal to 5, add one to the rounding digit and change all digits to the right of the rounding digit to zero.
So, Now The total cost to nearest dollar is $56.
Answer: Choice A) The figure and its image are similar, but not congruent, and the image has been translated 1 unit up.
The jump from (x,y) to (2x,2y) means we dilated by a scale factor of 2. The image is twice as large as its original. There is no way the two figures are congruent (the larger image has longer side lengths). Despite congruence not being preserved, the two figures are the same shape, so they are similar figures. After the dilation is done, the "+1" tacked onto the "2y" means we shifted every point up 1 unit.
Answer: 10.5 (equivalent to the fraction 21/2)
To get this answer, you set 10x-15 equal to 90 and solve for x. The reason why these two angles are equal is because they are vertical angles.
10x-15 = 90
10x-15+15 = 90+15 ...... add 15 to both sides
10x = 105
10x/10 = 105/10 ...... divide both sides by 10
x = 105/10
x = 21/2 is the answer in fraction form
x = 10.5 is the answer in decimal form
You'll use what the vertical angles theorem tells you to solve this.
The vertical angles theorem says that vertical angles are congruent, which is what the angle with (10x-15) and the opposite angle (90) are.
Since they are vertical angles, they are congruent so you can set up an equation where they are equal and solve for x.
(10x-15) = 90
1. Get rid of the parentheses.
10x-15 = 90
2. Add 15 to both sides.
10x = 105
3. Divide both sides by 10.
x = 10.5
Answer is:
x = 10.5
Answer:
kool beans
Step-by-step explanation:
A. laps per minute
B. laps
C. 1
D. 2
2) Gabriella swims 2 laps per minute. What is the unit rate?
A. 2
B. laps
C. 1
D. laps per minute
Answer to Number 1
Answer:
laps
_______________________________________________
Answer to Number 2
2
Step-by-step explanation:
Because unit rates are the numbers in the mathematical problem and the rate units are the problem.
Example:
2 laps per minute
The rate unit is laps per minute and the unit rate is 2.
