Airida [17]

Answer:

$0.25r + $5 = $12.50

Step-by-step explanation:

r represents the amount of rides Lacy went on during the day. If you do the problem in the correct order, you will get the answer

Step 1)

Subtract 5 from both sides

$0.25r + 5 (-5) = 12.50 (-5)

Step 2)

Divide by 0.25

0.25r (Divided by 0.25) = 7.50 (Divided by 0.25)

Step 3)

Answer

r = 30 rides

(Percentile) An apple juice producer buys all his apples from a conglomerate of apple growers in one northwest state. The amount
scoray [572]

Answer: 77% of the apples will contain at least 2.36 ounces of juice.

Step-by-step explanation:

Since the amount of juice squeezed from each of these apples is approximately normally distributed,

we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = the amount of juice squeezed in ounces.

µ = mean

σ = standard deviation

From the information given,

µ = 2.25 ounces

σ = 0.15 ounce

Looking at the normal distribution table, the z score corresponding 77%(77/100 = 0.77) is 0.74

Therefore, the number of ounces of juice, x will be

0.74 = (x - 2.25)/0.15

Cross multiplying, it becomes

x - 2.25 = 0.74 × 0.15

x - 2.25 = 0.111

x = 0.111 + 2.25

x = 2.36

Which expressions are equivalent to 35 + 30s - 45t?
stiv31 [10]
We have that
<span>35 + 30s - 45t

case A) 
</span>7⋅(5+30s−45t)---> 35+210s-315t-----> is not <span>equivalent 

case B)
</span>5(7+6s−9t)----> 35+30s-45t------> is equivalent to 35 + 30s - 45t

case C)
(−35−30s+45t)×(−1)----> 35+30s-45t---> is equivalent to 35 + 30s - 45t

case D)
 10×(3.5+3s−4.5)----> 35+30s-45---->  is not  equivalent 

case E) 
( 35/2 - 15s + 45/2t) ⋅ (-2)--->-35+30s-45t---> is not  equivalent 

the answer is
<span>B. 5(7+6s−9t)
C. (−35−30s+45t)×(−1)</span>
