Answer:

3/5 cup

Step-by-step explanation:

I start by changing the initial fraction of 3/4 into its decimal form of .75 so that it's easier to divide. I then divide it by 5 to find how much carbonated water you should use for a single cup of juice, which is .15 cups. Then, I multiply .15 times 4, which comes out to be .6, or 3/5.

Answer:

3/4 cups of carbonated water is needed by Andy to prepare 5 cups of fruit juice that means that he uses

(3/4)/5 = 3/20 cups of carbon. water for one cup of fruit juice for 4 cups he has to use (3/20)4=12/20

or 3/5 cups of carbonated water or in decimal form 0.6 cups

Answer: 9[tex]\pi[/tex]

Step-by-step explanation:

Sorry the pi sign looks weird. The formula for area of a circle is [tex]a=\pi r^2[/tex], so we have to substitute the radius with 3. The square of 3 is 9, so the answer is 9pi.

Answer:

The coordinates of point P along AB is (1,6.5)

Step-by-step explanation:

We shall use the internal division formula to split AB in the ratio 1 to 3

Mathematically, that would be;

(x,y) = (nx1 + mx2)/m + n , (ny2 + my1)/m + n

m = 1 , n = 3

(x1,y1)= (-1,2)

(x2,y2) = (7,8)

(x,y) = (3(-1) + 1(7)/1+3 , (3(8) + 1(2)/1+3

(x,y) = (-3 + 7)/4, (24 + 2)/4

(x,y) = 4/4 , 26/4

(x,y) = (1, 6.5)

Answer:

3

Step-by-step explanation:

if B has 30% more than A then 1.3 multiplied by 10= 13

so B contains 13 cups

13-10 is how many more B has than A

so the answer is 3

Step-by-step explanation:

Answer: [tex]2x^2-7x=72[/tex] , where  x= width of the rectangle ( in inches).

Step-by-step explanation:

Let x= width of the rectangle ( in inches).

Then its length =  2x-7 ( in inches).

Area of rectangle = Length × width

= (2x-7) × (x)

= 2x × x -7 ×x

= 2x²-7x

The area of the rectangle is 72 square inches.

[tex]\Rightarrow\ 2x^2-7x=72[/tex]

Hence, the equation that represents the given situation :

[tex]2x^2-7x=72[/tex]

Answer:

Step-by-step explanation:

The steeper the line (graph), the greater the slope and the greater the speed of that particular car.  It is instantly obvious that of the two lines shown, the yellow graph has the greater slope and thus the greater speed.

"The steeper the line, the greater the slope(speed).  "Car 1 is moving at a speed than car 2."

Answer:

64.3 Per hour

Step-by-step explanation:

If you divide 321.5 miles by 5 you get 64.3 per hour and to check you could times 64.3 by 5 to get 321.5

321.5 / 5 = 64.3

64.3 x 5 = 321.5

Answer:

d

Step-by-step explanation:

Answer:

y = 72°, x = 36°

Step-by-step explanation:

Step 1:

2x + 3x = 180°         Supplementary ∠'s

Step 2:

5x = 180°         Combine Like Terms

Step 3:

x = 180° ÷ 5         Divide

Step 4:

x = 36°      

Step 5:

3x + y = 180°        Supplementary ∠'s

Step 6:

3 ( 36 ) + y = 180°      Input x value

Step 7:

108° + y = 180°       Multiply

Step 8:

y = 180° - 108°         Subtract

Answer:

y = 72°, x = 36°

Answer:

h

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Given the function

f(x) = x^3 − x + 4 in the interval [1,2]

We are to find the value of x for which f(x) = 7

Substitute f(x) = 7 into the expression as shown!

f(x) = x^3 − x + 4

7 = x^3 − x + 4

x^3 − x + 4 -7 = 0

x^3 − x - 3= 0

x^3 -x = 3

x(x²-1) = 3

x²-1 = 3 and x = 3

x² = 3+1

x² = 4

x = ±√4

x = ±2

Since x lies within the interval, [1,2] hence the value of x is 2
