A rectangle has a length of x+5 cm and a width of x cm. The perimeter of the rectangle is 50 cm. What is the value of x?

Answers

Answer 1

Answer:x=10

Step-by-step explanation:

First let's create an equation:

2(x+5)+2x=50

2x+10+2x=50

4x+10=50

4x=40

x=10

Answer 2

Answer:

x = 10

Step-by-step explanation:

perimeter is the sum of all sides

2 sides = 'x+5' cm

2 sides = 'x' cm

2(x + 5) + 2x = 50

2x + 10 + 2x = 50

4x + 10 = 50

4x = 40

x = 10

how can you copy a angle using a straightedge, a compass, and a pencil, give step by step instructions

Answers

Answer:

Step-by-step explanation: Draw a working line, l, with point B on it.

Open your compass to any radius r, and construct arc (A, r) intersecting the two sides of angle A at points S and T.

Construct arc (B, r) intersecting line l at some point V.

Construct arc (S, ST).

Start with a angle BAC that we will copy.
1. Make a point P that will be the vertex of the new angle.
2. From P, draw a ray PQ. This will become one side of the new angle.

This ray can go off in any direction.
It does not have to be parallel to anything else.
It does not have to be the same length as AC or AB.

3. Place the compasses on point A, set to any convenient width.
4. Draw an arc across both sides of the angle, creating the points J and K as shown.
5. Without changing the compasses' width, place the compasses' point on P and draw a similar arc there, creating point M as shown.
6. Set the compasses on K and adjust its width to point J.
7. Without changing the compasses' width, move the compasses to M and draw an arc across the first one, creating point L where they cross.
8. Draw a ray PR from P through L and onwards a little further. The exact length is not important.
Done. The angle ∠RPQ is congruent (equal in measure) to angle ∠BAC.

Mary spent a total of $322.78 for a party. She spent $200.66 on food, plus an additional $30.53 for each hour of the party. How long was the party?

Answers

let h equal the length of the party in hours

200.66 + 30.53h = 322.78

now just solve for h :)
30.53h = 122.12
h = 4

so the party was 4 hours long

4 hours because you have to first subtract 322.78 and 200.66 then whatever you get you divide that by 30.53

The diagram below shows the number of ice cream cones sold in a day at a local ice cream shop.

Based on these results what is the most reasonable prediction of the number of chocolate chip ice cream cones that will be sold out of the next 240 cones sold?

Answers

Answer:

Step-by-step explanation:

B-60

EXPLANATION:

If he sold 8 vanilla, 28 double scoop and 12 chocolate chip, it means he sold 12 chocolate chip out of 48. So he sold 12/48 chocolate chip, which equals 1/4. If we write it in percentages, we will see that 1/4•100%=25%. Now we need to know how many chocolate chips would be sold in next 240 cones. In conclusion, we need to calculate 25% of 240. So if 240 is 100% and X is 25%, then 240•25=100X. If we solve that equation, we will see that X=60, so 25% of 240 equals 60. In conclusion, the right answer is B.

Because we weren't solving for x,y it's hard to say the order in which these should go so if it says that you're wrong again try switching them

Step-by-step explanation:

Looking at the first equation we know what p is equal to in terms of q so we can plug that value in for p in the second equation

2(q+3)+5q= -29

solve for q and get

2q+6+5q= -29

7q+6= -29

7q= -35

q= -5

Now that we know what q is equal to we can plug that value into the first equation and solve for p

p= -5+3

p= -2

Which tree grew at a slower rate for the first year?

Two trees were planted at the same time. Tree A grew 4.15 inches per month for the first year. Tree B grew 4.2 inches per month for the first year.

Answers

Tree A grew slower.
4.15 is less than 4.2 and Tree A is growing at the “lesser” rate, making it the slower growing tree.

Answer:

Tree A

Step-by-step explanation:

Let me put this question a different way. Which tree will be the tallest at the end of the year?

Well, let's think about it. 12 months later, Tree A will have grown 4.15x12=49.8 inches. Tree B will have grown 4.2x12=50.4 inches. As 50.4 is greater than 49.8, we can see it is Tree B that was the tallest at the end of the year. So we can conclude that Tree B grows faster. This would mean that Tree A grew at a slower rate for the first year.

Hope this helps
