Find the perimeter of a square garden if it’s area is 1369m2?
Answer:
Step-by-step explanation:
The area formula for a square is
[tex]A=s^2[/tex] where A is the area and s is a side measure. In a square, this side measure is the same (because all 4 sides in a square are the same). Therefore, our formula becomes:
[tex]1369=s^2[/tex]
Take the square root of both sides to find that a side measures 37 m.
The perimeter of a square is to add all 4 sides together (or to multiply the one side by 4):
4 * 37 = 148 m
A telephone company offers two different types of billing. The first choice is to pay $10.00 per month plus $0.09 per MB of data. The second choice is to pay $16.00 per month plus $0.07 per MB of data.
How many MB of data would you have to use in one month in order for both plans to cost the same amount? Explain how you determined your answer.
Answer:
0.09x +10 is the first choice
0.07x +16 is the second choice (set the two data plans equal to each other)
0.09x +10 = 0.07x +16 (subtract 0.07x from both sides)
0.02x +10 = 16 (subtract 10 from both sides)
0.02x = 6 (divide both sides b 0.02 to isolate x)
x= 300 MB of data (the answer)

PLEASE ANSWER ASAP! LOOK AT THE PIC ATTACHED: (please show work!)
Answer:
Answer is B
Step-by-step explanation:
Remember, perpendicular lines have opposite slopes. In order to do this, you just need to flip the sign (Change it to the opposite. For example, if it is 3, it would be -3), and change the slope to its reciprocal (For example, if it is 3, it would 1/3). Finally, since the equation is y = 1/2x + 10, the slope would change to -2x... so your answer is B

On Saturday, Alicia ran 2 miles. This was 0.3 miles farther than Henry ran. Write and solve an
an addition equation to find out how many miles Henry ran.
Answer: a - 0.3.
Step-by-step explanation;
Let a represent the number of miles that Alicia ran. The equation will be this: a - 0.3. You will subtract 0.3 from the number of miles that Alicia ran because her amount is 0.3 miles farther than what Henry ran.

First of all, try to understand the questions then try to make a pair of linear equations. After that make the coefficients of x or y equal in both RFD equations by multiplying them by suitable values then add or subtract them ,in such a way which will terminate any one of the variables. Then find the value of left variable. After that just put the value you have found just now In any of the equations and you'll really get the value of the second variable too.

Here is a list of ingredients for making 12 small cakes. 108 g margarine 180 g sugar 200 g plain flour 1 teaspoon baking powder 2 eggs. Joe is going to make 24 of the small cakes. Determine how much margarine he will need. Write your answer in a complete sentence.
Answer:
216g of margarine
Step-by-step explanation:
From the above question:
12 small cakes required 108g of margarine
If he would be making 24 of the small cakes, hence, that would be calculated as:
12 small cakes = 108g of margarine
24 small cakes = x
Cross Multiply
12 × x = 24 × 108g
x = 24 × 108g/12
x = 216g of margarine
Therefore, he would need 216g of margarine to make 24 of small cakes
