Martha combined different amounts of oramge juice, pineapple juice, and strawberry juice to make 1 850ml of fruit punch. The amo

allsm [11]

We have the following variable:
x = The amount of orange juice
We have the following equation:
x + (× + 100) + 1/2 × = 1850
We clear x:
(5/2) x + 100 = 1850
(5/2) x = 1850 - 100
(5/2) x = 1750
x = 1750 / ((5/2))
x = 700 ml
pineapple juice = × + 100 = 700 + 100 = 800 mL
strawberry juice = 1/2 × = (1/2) 700 = 350 mL
The difference is:
800 - 350 = 450 mL
Answer:
The difference in the amounts of pineapple juice and strawberry juice martin combined was:
450 mL

A car traveling at a certain speed will travel 76 feet per second. How many miles will the car travel in 3.1 hours if it maintai

liubo4ka [24]

Keeping in mind that, there are 5280 feet in 1 mile, and 60 minutes in an hour and 60 seconds in each minute, thus 60*60 seconds in an hour, or 3600 seconds.

$\bf \cfrac{76~\underline{feet}}{\underline{sec}}\cdot \cfrac{mile}{5280~\underline{feet}}\cdot \cfrac{3600~\underline{sec}}{hr}\implies \cfrac{76\cdot 3600~mile}{5280~hr}
\\\\\\
\cfrac{570~mile}{11~hr}\approx 51.\overline{81}\frac{mile}{hr}\\\\
-------------------------------\\\\
\textit{how many miles does it do in 3.1hrs?}\quad \cfrac{570}{11}\cdot 3.1$

The bookstore at suntan U Had a sale on school t shirts. Thursday they sold 45 of the marked down t-shirts for a total of 406.50

Kisachek [45]

Answer:

The number of women's shirt sold is 32.

The number of men's shirt sold is 13

Step-by-step explanation:

Total number of T shirts sold on Thursday = 45

Total amount it was sold for : 406.50

Cost of each women's t shirt = 9.25

Cost of each men's t shirt = 8.50

Here, let the number of women's shirt sold= k

So,number of men's shirt = Total shirts sold - Women's shirt

= 45 - k

Also, total amount earned = Amount earned from men's shirt + amount earned from women's shirt

or, 406.50 = k(9.25) + (45 -k)(8.50)

⇒ 406.50 = 9.25 k - 8.50 k + 382.5

or, 24 = 0.75 k

⇒ k = 24/0.75 = 32

Hence, the number of women's shirt sold is 32

And the number of men's shirt sold = 45 - 32 = 13
