The cost of a 4 pack of apple juice is $ 2.24. Write an equation that relates the cost in dollars, y, to the number of apple juice cartons, x.
Answer:
Cost = y/x
Step-by-step explanation:
The cost of a 4 pack of apple juice is $ 2.24.
We need to write an equation that relates the cost in dollars, y, to the number of apple juice cartons, x.
As 4 packs = $2.24
1 pack = 0.56
So, the equation can be :
Cost = y/x
What is the slope of the line
Answer:
B) 4
Step-by-step explanation:
Use the slope formula:
slope [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) = (1 , -2)\\(x_2 , y_2) = (2 , 2)\\[/tex]
Plug in the corresponding numbers to the corresponding variables:
slope:
[tex]m = \frac{2 - (-2)}{2 - 1} \\m = \frac{2 + 2}{2 - 1}\\m = \frac{4}{1} = 4[/tex]
B) 4 is your answer.

In the morning, a farm worker packed 10 pints of raspberries every 4 minutes. In the afternoon, she packed 3 pints of raspberries every 2 minutes. What was the difference between her morning and afternoon packing rates, in pints per hour?
Answer:
In the morning
(3/4) (strawberries / minutes) * (60/1) (minutes / hours) = 45 (strawberries / hours)
in the afternoon
(2/3) (strawberries / minutes) * (60/1) (minutes / hours) = (40 strawberries / hours)
the difference between your morning and afternoon packing rates, in pints per hour is 45-40 = 5 (strawberries / hours)
Step-by-step explanation:
.
Answer:
60 pints
Step-by-step explanation:
10 pints every 4 minutes = 10(15) pints every 4(15) minutes which is the same as 150 pints per 1 hour
3 pints every 2 minutes = 3(30) pints every 2(30) minutes which is the same as 90 pints per 1 hour
150 - 90 = 60 pints difference
Henri and Talia are mixing paint for an art project. They mixed p liters of red paint, 0.6 liters of blue paint, and p – 0.4 liters of white paint. They then divided the mixture evenly into 2 jars. If each jar contains 2.4 liters of paint, how much red paint did they use? Use numbers to fill in the blank.
Answer:
I think the answer is 3.8.
Step-by-step explanation:
Because there is 0.6 for the blue paint and 0.4 for the white paint, and p=red paint. If you divide all 3 of them equally into 2 jars, you have add 0.4 and 0.6 together and then divide by 2, then substract it from 2.4. You will get 1.9, then multiply 1.9 by 2, that is how much Henri and Talia used for the red paint, which is 3.8 liters.

-these triangles are not similar
Answer:
Option (4)
Step-by-step explanation:
From the picture attached,
Side lengths of the triangles have been given in the picture attached.
If these triangles are similar, their corresponding sides will be proportional.
By this property of similarity,
[tex]\frac{19.5}{5}= \frac{20}{8}[/tex]

Answer:
equivalent expression of [tex]\sqrt[6]{g^5},\: if\:g>0[/tex] is [tex]\mathbf{g^{\frac{5}{6}}[/tex]
Option D is correct option.
Step-by-step explanation:
We need to find equivalent expression of [tex]\sqrt[6]{g^5},\: if\:g>0[/tex]
The equivalent expression can be found using exponent rules.
We know that: [tex]\sqrt[6]{x} = x^{\frac{1}{6}}[/tex]
Using this and solving our given expression
[tex]\sqrt[6]{g^5},\: if\:g>0\\=(g^5)^{\frac{1}{6}[/tex]
Using exponent rule: [tex](a^m)^n=a^{m*n}[/tex]
[tex]=g^{\frac{5}{6}[/tex]
So, equivalent expression of [tex]\sqrt[6]{g^5},\: if\:g>0[/tex] is [tex]\mathbf{g^{\frac{5}{6}}[/tex]
Option D is correct option.

Create two equivalent rates to 65 km/h with units for distance and time that are not kilometres and hours. At least one should be a unit rate.
Answer: 18.05556
Step-by-step explanation: 65 Kilometer/Hour (km/h) =. 18.05556 Meter/Second (m/s) Kilometer/Hour : Kilometers per hour (also spelling: kilometer per hour) is a unit of speed, defined as the number of kilometers travelled in one hour. The symbol of kilometer per hour is km/h or km•h−1.
Hopefully this helps :D
The units for distance and time are 3250/3 m/min and 325/18 m/s
What is unit rate?A unit rate means a rate for one of something. We write this as a ratio with a denominator of one.
For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, we need to create two equivalent rates to 65 km/h with units for distance and time that are not kilometers and hours.
So,
65 km/h = 65 x 1000 m / 60 min = 3250/3 m/min
65 km/h = 65 x 1000 m / 3600 sec = 325/18 m/s
Hence, the units for distance and time are 3250/3 m/min and 325/18 m/s
