Answer:

Berry

Step-by-step explanation:

Before the additional input, 5 people said they like berry, and 7 people said vanilla. The additional input shows that 3 more people like berry than before. 5 + 3 = 8, therefore, 8 people now like berry. Because 8 > 7, more people like berry than vanilla.

When Amy roller-skates, she moves 110 yards per minute. What is her speed in miles per hour? Round your answer to the nearest hu

Softa [21]

Answer:

Speed of Amy is 3.75 miles per hour.

Step-by-step explanation:

We have, speed of Amy = 110 yards per minute

This means, she covers 110 yards of distance in 1 minute.

Now, to convert the speed of Amy into miles per hour, we will first convert the distance from yards into miles and then convert time from minutes to hour.

We know that,

1 yard = 3 feet

∴ 110 yards = 3 × 110 feet = 330 feet

Now, we also know that,

5280 feet = 1 mile

∴ 1 feet = $\frac{1}{5280}$ miles

So, 330 feet = $\frac{1}{5280}\times330$ = $\frac{1}{16}$ miles

∴ 110 yards = 330 feet = $\frac{1}{16}$ miles

Now, 60 min = 1 hr

∴ 1 min = $\frac{1}{60}$ hrs

So, 110 yards = $\frac{1}{16}$ miles and 1 min = $\frac{1}{60}$ hr

So, we can say that, Amy covers a distance of $\frac{1}{16}$ miles in

$\frac{1}{60}$ hr.

We know that,

$speed=\frac{distance}{time}$

$speed=\frac{(\frac{1}{16}) miles}{(\frac{1}{60})hr}$

$speed=\frac{60}{16} miles/hr = 3.75 miles/hr$

Therefore, the speed of Amy in miles/hr is 3.75 miles/hr.

F) 16 - p = 12 g) 18 - 2p = 6 h)p2+ 4 = 9 i)p4- 3 = 1 **MUST SHOW YOUR WORK**

mestny [16]

f) 16 - p = 12 minus 12
4 - p = 0 plus p
p = 4
g) 18 - 2p = 6 divide by -2
-9 + p = -3 plus 9
p = 6
h) p x 2 + 4 = 9 divided by 2
p + 2 = 4.5 minus 2
p = 2.5
i) p x 4 - 3 = 1 plus 3
p x 4 = 4 divided by 4
p = 1
