Each base angle would be 50 degrees because in an isosceles triangle the base angles have to be the same. Also in any triangle the angles have to add to 180 degrees.

Solve the system of equations using any appropriate method: 5x + 2y = -4 and -x + 2y = 8
Maru [420]

Answer:

A

Step-by-step explanation:

-x + 2y = 8

5x + 2y = -4

+ x. -2y. -8

6x = -12

÷6. ÷6

x = -2

5(-2) + 2y = -4

-10 + 2y = -4

+10. +10

2y = 6

÷2. ÷2

y = 3

Ruby plans to make 3 quilts per month until she makes 15 quilts. She figures this will take 1/5 month. Which is NOT a reason why
pashok25 [27]

Answer: c)She should have multiplied 15 by 3 instead of dividing.


Step-by-step explanation:

Number of quilts Ruby plan to make in one month= 3

which means if Ruby makes more than 3 quilts, the time will be more than 1 month.

To find the number of months to make 15 quilts, she need to divide 15 by 3

Thus, the number of months to make 15 quilts=5

Her answer was 1/5 which was absolutely wrong as if she is making 3 quilt in 1 month then in 1/5  month she would make fewer than 3 quilts.

She divides 3 by 15 instead of 15 by 3, thus but the unit is quilts not months.

Thus the only wrong option is c)She should have multiplied 15 by 3 instead of dividing.

A gardener has a circular flower bed with a radius of 17 feet. If she wants to make a square flower bed with the same area as th
mylen [45]

We know that

• The radius is 17 feet.

First, we find the circular area

\begin{gathered} A=\pi(r)^2 \\ A=3.14(14)^2\approx3.14\cdot196\approx615.44ft^2 \end{gathered}

This means the square flower bed will have an area of 615.44 square feet. So, we find its sides with the formula for squared areas

\begin{gathered} A=l^2 \\ 615.44=l^2 \\ l=\sqrt{615.44}\approx24.808 \end{gathered}<h2>Therefore, the bed should have sides of 24.808 feet, approximately.</h2>
