Which is bigger -6 1/3 or -6.375

levacccp [35]

-6 1/3 because it looks less than -6.375 which would mean that it is in fact bigger on the number scale.

Schach [20]

Answer:

1. 30 student

2. 120 student's didn't vote

3. 7 quarters

Step-by-step explanation:

1. first, see how many games can be played:

45÷3 = 15

then, multiply the number of games by two because 2 students can play per game

15 • 2 = 30

2. first, figure out what percent of students did not vote:

100 - 60 = 40%

then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:

300 • .40 = 120 student's didn't vote

3. first, find how much 9 dimes is:

1 dime = $0.10

9 dimes = 9 • $0.10 = $0.90

then, find how much money kerry had:

$2.65 - $0.90 = $1.75

finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:

1 quarter = $0.25

$1.75 ÷ $0.25 = 7 quarters

John has a map that shows a rectangular park 1 1/4 cm : 8 yd. on the map, the width of the park is 2 1/2 cm. What is the parks a

Ber [7]

Answer:

16 yd. This is the park's actual length.

Step-by-step explanation:

Write and solve an equation of ratios:

1 1/4 cm 8 yd

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

2 1/2 cm x

Note that 2(1 1/4 cm) = 2 1/2 cm, so the above equation becomes:

1 8 yd

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

2 x

Solving for x, we get x = 16 yd. This is the park's actual length.

Find the measure of the indicated angle to the nearest degree

vagabundo [1.1K]

Answer:

6). Option A

7). Option C

8). Y = 62°

Step-by-step explanation:

6). Let the missing angle = x°

By applying cosine rule to find the missing angle,

cos(x°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{35}{37}$

x = $\text{cos}^{-1}(\frac{35}{37})$

x = 18.92°

x ≈ 19°

Option A is the answer.

7). Let the missing angle = x°

By applying cosine rule in the given triangle,

cos(x°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(x°) = $\frac{37}{38}$

x = $\text{cos}^{-1}(\frac{37}{38})$

x = 13.17

x = 13°

Therefore, Option C is the answer.

8). tanY = 1.8807

Y = $\text{tan}^{-1}(1.8807)$

Y = 62°
