Lauren has finished 25% of the 120 push ups she needs to do for softball
practice. How many of the total push ups has she now finished?
Answer:
30 pushups
Step-by-step explanation:
25/100 = x/120
so, 120x25 = 100x
3000 = 100x
3000/100= x
x = 30
so, Lauren has completed 30 push-ups.
Answer while showing work I need u to show ur work and answer
Answer:
7cm
Step-by-step explanation:
One side of a square is increased by 8 cm, let us say the length got increased by 8 cm. So we have length of x + 8 cm
An adjacent side, the width, decreased by 2 cm. So we have width of x - 2cm
Perimeter of rectangle = 2(length + width)
40 = 2( (x + 8) + ( x - 2) )
40 = 2( 2x + 6)
40 = 4x + 12
28 = 4x
x = 7 cm
That is 7 cm of the length of the side of the square
|2x+8|−4= -12 (solve for x)

Answer: y=5
Step-by-step explanation:
The line only has a value of 5, regardless of the value of x. So the slope of this line is "o," the vlaue of x has no influence on the value of y.
y = mx + b
y = ox + b
b is the y-intercept, the value of y when x = 0. That would be 5, again:
y = 0x + b
y = b
y = 5

the first one 1. = 1
the second one 2. = 1
Answer:
A) 1
B) [tex]\frac{2}{1}[/tex], or 2
Explanation:
In a fraction, when both the numerator and the denominator (top and bottom numbers) are the same, the fraction is equal to one. If the numerator (top #) is larger than the denominator (bottom #), then the answer will be larger then 1.
If the numerator is exactly twice the denominator then the answer is 2

The hypotenuse of a right triangle is 65 cm, if one of its sides is 25 cm, find the length of the other side and it's perimeter
I will name you brainless if you give correct answer
Answer:
Other side = 60
Perimeter = 150
Step-by-step explanation:
Using Hypothenuse formula
25²+B²=65²
625+B²=4225
B²=4225-425
B²=3600 (Bring Square to the other side to become Square root)
B=√(3600)
B=60
Perimeter:(Sum of all side)
60+65+25
150

A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes.
What integer represents the rate of motion of the submarine?
–
feet per minute
Okay so our starting point is - 1,260 feet
Now it is descending (-) 5 ft per minute for 12 minutes
So we multiply -5 (negative because it is descending) by 12
-5 x 12 = -60
So now we add -60 to -1,260
This would be -1,320
So the submarine's new position in relation to the sea level is -1,320
Hope this helped. Have a great day!
that would be -1260 + 12(-5) = -1260 - 60 = -1320 feet

Answer:
(B) 4
Step-by-step explanation:
Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...
3 + 8 = 11
This tells you A = 8, so the top number is 1983, and the middle number is B78.
Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...
1 + 9 + B = <something ending in 4>
We know the something cannot be 04 or 24, so must be 14. Then ...
10 + B = 14 ⇒ B = 4
__
So, the whole sum is ...
1983 +478 = 2461
and the letter values are ...
A = 8B = 4D = 2Answer:
B is 4.
Step-by-step explanation:
If we start by the ones place and add we know that to get a one the total must be 11. 11-3 = 8. Therefore A = 8.
Now we move to the tens place, since we know A is 8 we can substitute it there. Don't forget to add the one from the 11 we got. 1+8+7 = 16
Now we move to the hundreds place and we carry our one from 16 so now it's 1 + 9 + ? = 4, if we know that our total needs to be 14 in order to have the 4 there- 1 + 9 is 10 we can do 10 + 4 and that gets us 14. So B is 4.

Find the value of x and y
Answer:
x = 10 and y = 15
Step-by-step explanation:
The arrows on lines AB and CD indicate that they are parallel. This means that we have to look for Z-angles (I don't know if they are called the same where you're from but I hope you recognise the term). This means that ∠ABC = ∠BCD
5x - 20° = x + 20°
4x = 40°
x = 10°, which gives us the first answer.
The angle formed by points ACE (a straight line) is 180 degrees. Lets refer to this as angle ACE. We also know this angle consists of angle ACB, BCD and DCE. This gives us the following equation:
angle ACE = angle ACB + x + 20° + y + 20° = 180°
angle ACB + x + y + 40° = 180°
angle ACB = -x - y + 140°
Inserting the x we found earlier this gives
∠ACB = - y + 130°
Now we can find a second equation to describe ACB by looking at the triangle it is inside. The angles in a triangle always add up to 180°, giving the following expression:
4y - 25° + 5x - 20° + ∠ACB = 180°
Substituting x again gives
4y - 25° + 50° - 20° + ACB = 180°
ACB = 180 - 4y - 5° = 175° -4y
Combining the two expressions for ACB gives the final equation to solve:
175° - 4y = -y + 130°
-3y = -45
y = 15
