Answer:
above is the solution to the question
Answer:
60cm
Step-by-step explanation:
20/4 = 5
one side of the square = 5cm
l (length) = 4 squares
w (width) = 2 squares
p (perimeter) = 2(5l) + 2(5w)
p = 2 x 20 + 2 x 10
p = 40 + 20
p = 60
URGENT I NEED HELP ANSWERING THESE
I can only answer 5, use my answer to help find 6.
Answer:
The volume is 259,824,773,000
Step-by-step explanation:
r, or radius is half of the diameter. So we are left with (4 * pi (also known as 3.14159)* 3958.5^3)/3
(7.7947432 * 10 ^ 11) / 3 = 779,474,320,000 / 3
Which is equal to 259,824,773,000 as the volume.
I hope this solves 5 and helps you with 6.
A biker travels 8 miles in 10 minutes. Another biker travels 20 miles in 30 minutes. Do these two
rates form a proportion? Explain.
These both rates are not proportional because if 8 mile in 10 minutes and 20 miles in 30 minutes .. So 10 times 3 equals 30 minutes but if we multiply 8 times 3 is equal to 24. So there are not proportional.. I hope this helped

6y + 2 + 3 + 14y
Using the expression shown, add like terms and produce an equivalent expression.
Answer:
20y + 5
Step-by-step explanation:
6y + 2 + 3 + 14y
20y + 2 + 3
20y + 5
Have an amazing day!
PLEASE MARK BRAINLIEST!
Answer:
Added Like Terms: 20y + 5
Equivalent Expression: 12y + 8y + 4 + 1
Explained:
Add like terms. Both 6y and 14y have a variable of y, so they can be added.
6y + 14y = 20y
Next, add the next set of like terms. 2 and 3 both don't have a variable, so you can add em'.
2 + 3 = 5
There are no more like terms to add since 20y has a variable and 5 doesn't, leaving you with the answer 20y + 5.
As for the equivalent expression, I just created another expression that equals 20y + 5.

PLEASE HELP ME LOOK AT THE PHOTO
Answer:
Please mark me Brainliest.
Step-by-step explanation:
1.) B is closer to 0
2.) -a is farthest left on the number line, because absolute value of a is greater than absolute value of b. So you know a is greater in positive.
3.) Absolute value of a is 8. Absolute value of b is 5. Now on a number line -8 will be farthest left. (-8<5 and 5<8)
4.) If you do a - & + then only the first part will be true the rest will be false.
5) If you do a + & + then the equation would be false and then a true.

Answer:
Middle School In Favor: 25%
Middle School Not in Favor: 75%
High School In Favor 20%
High School Not In Favor 80%
Step-by-step explanation:
For the middle school in favor, we need to find the percent, which is 50 out of 200, so its 1/4, 25%
So the rest of the middle school is not in favor, which is 75%
High school is 60 not in favor, so we need to find the percentage. So 60 out is 300 is 20%
And we just subtract 20 from 100 which leaves us with 80

Solve for y.
6 = 2 (y+2)
y = ___
y=1!!!!!!!!!!!!!!!!!!!
Answer:
[tex]y=1[/tex]
Step-by-step explanation:
Given the following question:
[tex]6=2(y+2)[/tex]
In order to find the answer, we will rewrite the equation by switching the sides and then solve by dividing on both sides.
[tex]6=2(y+2)[/tex]
[tex]2\left(y+2\right)=6[/tex]
[tex]\frac{2(y+2)}{2} =y+2[/tex]
[tex]6\div2=3[/tex]
[tex]y+2=3[/tex]
[tex]2-2=0[/tex]
[tex]3-2=1[/tex]
[tex]y=1[/tex]
Hope this helps.

Answer:
_____________________________
Answer:
0.22
Step-by-step explanation:
To find the experimental probability, we first find the total amount of responses and then divide it by the number of responses going to city A. The total is 100, and the number of responses going to city A is 22.
Now divide the number of responses of going to city A by the total.
Experimental probability = 22/100, or 0.22
