Answer:

Both rates and ratios are a comparison of two numbers. A rate is simply a specific type of ratio. The difference is that a rate is a comparison of two numbers with different units, whereas a ratio compares two numbers with the same unit. For example, in a room full of students, there are 10 boys and 5 girls. This means the ratio of boys to girls is 10:5.

M(3, 4) is the midpoint of mc010-1.jpg The coordinates of S are (4, 1). What are the coordinates of R?

USPshnik [31]

Midpoint formula : (x1 + x2) / 2, (y1 + y1) / 2
(4,1)....x1 = 4 and y1 = 1
(x,y)....x2 = x and y2 = y
sub
(4 + x) / 2 , (1 + y) / 2 = 3/4

(4 + x) / 2 = 3
4 + x = 3 * 2
4 + x = 6
x = 6 - 4
x = 2

(1 + y) / 2 = 4
1 + y = 4 * 2
1 + y = 8
y = 8 - 1
y = 7

ur other endpoint, R, is (2,7)

The fifth graders to plant a butterfly garden. Clover grows in ½ of the garden, daisies in ¼ of the garden, coneflowers in ⅛ of

Answer:

Fraction of the garden used = $\frac{5}{8}$

Step-by-step explanation:

The fifth graders to plant a butterfly garden.

We are given that

Clover grows in ½ of the garden

Daisies grow in ¼ of the garden

Coneflowers grow in ⅛ of the garden

milkweed grows in ⅛ of the garden

The fifth graders notice that the butterflies land on the clover and milkweed.

We are asked to find out the fraction of the garden that the butterflies used.

Fraction of the garden used = clover + milkweed

Fraction of the garden used = $\frac{1}{2} + \frac{1}{8}$

The LCM of 2 and 8 is 8

Fraction of the garden used = $\frac{4 +1}{8}$

Fraction of the garden used = $\frac{5}{8}$

Therefore, the butterflies used $\frac{5}{8}$ fraction of the garden.

5. Use the Pythagorean theorem to estimate the length of the unknown side of the right triangle. Explain why

photoshop1234 [79]

Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

6 = b

c= 8

a=?

now u just replace

a^2 + 6^2 = 8^2

a^2 + 32 = 64

a ^2 = 64-32

a^2 = 32

$\sqrt a^{2} = \sqrt32$

a = 5.65685424949

if you rounded

a = 5,7
