Answer:

Answer:

(7, 2).

Step-by-step explanation:

The median from A intersects BC at it's midpoint.

To find the midpoint of BC:

This is (x1, y1) where x1 = (sum of the x_values of B and C) / 2)  and where y1

= (sum of the y_values of B and C) / 2)

This is (2+12)/2,  (1 + 3)/2

= (7, 2).

If 120% is 360,what is 100%

Answers

Answer:

300

Step-by-step explanation:

We know

120% = 360

100% = ?

We cross multiply by 100 and divide by 120.

(360 x 100) ÷ 120 = 300

So, the answer is 300

in a recent survey, 336 out of 500 people chose reallygood cola as their favorite soft drink. If a similar survey was conducted out of 2,000 people, how many people would choose reallygood cola as their favorite soft drink? explain.

Answers

In the first survery (336)/(500) considered cola.
Assuming we can extrapolate this ratio, all we have to do is get the same ratio, but out of 2000 people.
(336)/(500) * (4)/(4) \n (1344)/(2000)
The answer is 1344 people.

Sally filled a measuring cup with 3/4 of a cup of vegetable oil then she poured 1/4 of a cup of oil into a frying pan

Answers

Oh, let's measure and cook together, my dear!

Sally started by filling a measuring cup with 3/4 of a cup of vegetable oil. That's a good amount of oil!

Then, she poured 1/4 of a cup of oil into a frying pan. Now we're getting things sizzling!

So, if we add the 3/4 cup and the 1/4 cup together, we get:

3/4 + 1/4 = 3/4 + 2/4 = 5/4

That means Sally poured a total of 5/4 (or 1 and 1/4) cups of oil in total.

Now, we're all set to cook up something delicious! Enjoy your culinary adventures, my dear! ‍

Jude has seven times as many dimes as nickels their value is $5.25 how many nickels does he have.49
15
7

Answers

Let dimes be represented by d and n for nickels;
1 dime= 0.1 dollars
1 nickel=0.05 dollars
0.1d+0.05n=5.25
d=7n
so,
0.1(7n)+0.05n=5.25
0.7n+0.05n=5.25
0.75n=5.25
n=7
There are 7 nickels and 49 dimes
1 nickel = $0.05
1 dime = $0.10

n - number of nickels
7n - number of dimes

A equation:
 
0.05n + 0.1 · 7n = 5.25
0.05n + 0.7n = 5.25
0.75n = 5.25          |divide both sides by 0.75
n = 7

Answer: He have 7 nickels.

The function t(x) = 3x + 1 determines how many cans of green beans a food truck needs to stock on board, where x is the number of shifts the crew is going to work in the truck. The crew uses c(t(x)) to find the amount of money to spend on green beans. The function c(x) = x + 4. Solve for how much money must be spent when the crew is going to work 2 shifts.

Answers

Answer: The amount of money he must be spent when the crew is going to work 2 shifts is $11.

Step-by-step explanation:

Since we have given that

the function t(x)=3x+1 determines how many cans of green beans a food truck needs to stock on board , where x is the number of shifts the crew is going to work in the truck.

And the function c(x)= x+4

Since the crew uses c(t(x)) to find the amount of money to spend on green beans .

So, we will use "Composition of functions ":

c(t(x))=(3x+1)+4\n\nc(t(x))=3x+5

Since the crew is going to work 2 shifts , so our answer will be

c(t(2))=3(2)+5\n\nc(t(2))=6+5\n\nc(t(2))=11

Hence, the amount of money he must be spent when the crew is going to work 2 shifts is $11.

t ( x ) = 3 x + 1
c ( x ) = x + 4
c ( t ( x ) ) = 3 x + 1 + 4 = 3 x + 5
When x = 2:
c ( 2 ) = 3 * 2 + 5 = 6 + 5 = 11
Answer: $11 must be spent on green beans.
