257 is the answer to this question
Answer:
Step-by-step explanation:
<u>In right triangle sum of two angles is 90°</u>
- 4x + x = 90°
- 5x = 90°
- x = 90°/5
- x = 18°
<u>Angle y is exterior angle and equals non-adjacent interior angles</u>
- y = 4x + 95° =
- 4*18° + 95° =
- 72° + 95° =
- 167°

Step-by-step explanation:
a. Marisa drives 112 miles in 1 hour and 45 minutes, which means her speed is 64 miles per hour.
Speed = Distance / Time
= 112 / 1 45/60
= 112 / 1 3/4
= 112 × 4/7
= 64 miles per hour.
TRUE
b . If 6 pens cost $7.74, then 7 pens cost $9.03.
Cost of one pen = $7.74/6 = $1.29
Cost of 7 pens = $1.29 × 7 = $9.03
TRUE
c. If Raymond drives at a speed of 57 miles per hour, then it takes him 4 hours and 10 minutes to drive 256.5 miles.
Speed = Distance / Time
Speed = 256.5 / 57 = 4.5 = 4 hours 30 minutes
FALSE
d. If 17 identical cans of soup cost $38.59, then 3 of the cans must cost $6.81.
Cost of one can = $38.59 / 17 = $2.27
Cost of 3 cans = $2.27 × 3 = $6.81
TRUE
e. Mr. Mayes buys two dozen eggs for $8.40, which means that he pays 70 cents per egg.
A dozen = 12
2 dozens = 12 × 2 = 24
Cost of one egg = $8.40 / 24 = 0.35 = 35 cents
FALSE
The next step in the series will be Option B
<h3>What is a Series ?</h3>
A series is the sequence of object in pattern.
From the given figure it can be seen that the red and blue colour semicircle are shifting alternately , and the number series is increasing by 1
Therefore the next step is red on the right side , blue on the left side and no. 4 written on blue
Therefore Option B is the right answer.
