Help me with questions 5 and 7 please show your work !

Mathematics
1 answer:
seraphim [82]2 years ago
7 0

Answer:

5) x = 77

7) b = 210

Step-by-step explanation:

5) 11 = X/7

multiply both sides by 7. doing this gets rid of the 7 on the right side of the equation.

(7)(11) = x

77 = x

7) 14 = b/15

same thing as above! multiply both sides by 15.

(15)(14) = b

210 = b

Hope this helps you!

Determine if AB¯¯¯¯¯¯¯¯ and CD¯¯¯¯¯¯¯¯ are parallel, perpendicular, or neither. Given: A (−1, 3), B (0, 5), C (2, 1), D (6, −1)
dolphi86 [110]

Answer:

perpendicular

Step-by-step explanation:

To determine if AB and CD are  parallel, perpendicular, or neither, we need to get the slope of AB and CD first

Given A (−1, 3), B (0, 5),

Slope Mab = 5-3/0-(-1)

Mab = 2/1

Mab = 2

Slope of AB is 2

Given C (2, 1), D (6, −1)

Slope Mcd = -1-1/6-2

Mcd = -2/4

Mcd = -1/2

Slope of CD is -1/2

Take their product

Mab * Mcd = 2 * -1/2

Mab * Mcd = -1

Since the product of their slope is -1, hence AB and CD are perpendicular

Allushta [10]

Answer:

11 bottles

Step-by-step explanation:

make a proportion because if you're using the same rate proportions can show that it's equal

\frac{7}{90} = \frac{x}{140}

cross multiply

7 *140= 980

divide the answer by 90 to find x

980/90= 10.8

round to 11 because you can't have 10.8 bottles
