Answers

Answer 1

Answer:

72 lb

Step-by-step explanation:

Write and solve an equation of ratios:

80 pounds             x

----------------- = ------------------

100 pounds      90 pounds

Cross multiplying, we get (100 pounds)x = 7200, or x = 72 pounds.

The 80 pound child's weight includes 72 pounds of water.

Angle SPR and angle RPQ are complementary. Find the measure of angle RPQ.

Answers

Answer:

53 degrees

Step-by-step explanation:

Complimentary angles are angles whose sum equals 90 degrees.

90-37 = 53

Answer:

m∠RPQ = 53°

53 degrees

Step-by-step explanation:

When two angles are complementary angles, it means they add up to 90 degrees (Ex: a 10° angle and 80° angle would be complementary).

Therefore, if ∠SPR and ∠RPQ are complementary, then

m∠SPR + m∠RPQ = 90°

since you are given that m∠SPR = 37°, you can plug that in for m∠SPR to find m∠RPQ:

m∠SPR + m∠RPQ = 90°

37° + m∠RPQ = 90°

m∠RPQ =  90° - 37°

m∠RPQ = 53°

Which one of the following fractions is the largest?

Answer:

[tex]x = \frac{360}{11} [/tex]

[tex]y = \frac{60}{11} [/tex]

Step-by-step explanation:

Since 6y=x plug 6y in for x on the top equation.

[tex]2(6y) - y = 60[/tex]

[tex]12y - y = 60[/tex]

[tex]11y = 60[/tex]

[tex]y = \frac{60}{11} [/tex]

Plug y=60/11 into 6y=x

[tex]6( \frac{60}{11} ) = x[/tex]

[tex] \frac{360}{11} = x[/tex]

Plug 360/11 into 2x-y=60

[tex]2( \frac{360}{11} ) - \frac{60}{11} = 60[/tex]

[tex] \frac{720}{11} - \frac{60}{11} = 60[/tex]
