Answer:

390 cal

Step-by-step explanation:

We have the ratio of 50 : 260, which can be simplified to 25 : 130, which as 25 is a factor of 75 we can use to figure ot the answer.

Now we just need to multiply both sides pf the ratio by 3 to get back too 75 : x

130 * 3 = 390, so the ratio is 25 : 390

Answer:

390 calories

Step-by-step explanation:

Divide 260 and 50, to find how much calories are in 1 gram.

260/50=5.2

1 gram=5.2 calories.

Now multiply 75 with 5.2 to find how many calories are in 75 g.

75 x 5.2=390

<u>Final answer</u>

390 calories

The diameter of the base of the cone measures 8 units.

weeeeeb [17]

Answer: $32\pi$ cubic units.

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

$V_{cone}=\frac{1}{3}\pi r^2h$

Where "r" is the radius and "h" is the height.

You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

$r=\frac{8units}{2}\\\\r=4units$

Since you already know that height and the radius, you can substitute them into the formula. Then, the volume of this cone is:

$V_{cone}=\frac{1}{3}\pi (4units)^2(6units)$

$V_{cone}=32\pi \ units^3$

Determine if the ordered pair (6, 4) is a solution to the inequality

Ugo [173]

Answer:

$\Large \boxed{\mathrm{Option \ D}}$

Step-by-step explanation:

(6, 4)

x = 6 and y = 4

y > -1/2x + 7

Plug in the values to check if it is true.

4 > -1/2(6) + 7

4 > -3 + 7

4 > 4

This statement is false.

(6, 4) lies on the line.

A sector of a circle has a central angle of 45 . Find the area of the sector if the radius of the circle is 15 cm.

prohojiy [21]

Answer:

A = 28.125 * pi cm^2

A = 88.357 cm^2

Step-by-step explanation:

Area of a sector is 1/2 r^2 theta where theta is in radians

convert 45 degrees to radians

theta = 45 * pi/180 = pi/4

A = 1/2 * 15^2 * pi/4

A =1/2 * 225 * pi/4

A = 28.125 * pi cm^2

A = 88.357 cm^2

Can someone please help me ?

Alex

Answer:

B. π(3/2)²h

(27/4)π cubic inches

Step-by-step explanation:

A. The formula for the volume of a cylinder is ...

V = πr²h

The radius (r) is half the diameter, so for a diameter of 3 inches, the radius is 3/2 inches. When this is put into the formula, the volume is ...

V = π(3/2)²h . . . . . . matches choice B

B. When h=3, the volume evaluates to ...

V = π(9/4)(3) = (27/4)π . . . . cubic inches
