Step-by-step explanation:

To compare the number of apples to oranges

Number of apples = 12

Number of oranges = 10

Number of apples in terms of oranges :

12 /10 = 1.2

Number of apples = 1.2(number of oranges)

If number of apples = x

Number of oranges = y

x = 1.2y

There are 1.2 times the number of apples than number of oranges.

Answer:

54

Step-by-step explanation:

first find x:

21x-9=14x+12

21x=14x+21

7x=21

x=3

now substitute

21(3)-9

63-9=54

Answer: 1

5+10=−20+1501+10−10=−20+150−10

Subtract the numbers

Answer:

$26.25

Step-by-step explanation:

I'm not completely sure if I did this right because I haven't used this in a while, but let's say sodas are x and hot dogs are y. The first equation would be  3x+4y=15 and in order to solve for x or y you have isolate them to seperate sides because if there is not letter on the other side, it will just end up being zero... if that makes sense. subtract 3x so the equation is now 4y=15-3x and divide everything by 4, to make the equation y=3.75-3/4x. Do the same thing but subracting the 4y and dividing by 3 to get the x value. Now we're left with y=-3/4+3.75 and x=5-4/3y (or x=5-1 1/3y). remember that x=sodas and y=hotdogs. The equation we need to create has seven hot dogs and no sodas, so we simply need to take the equation for y and substitute y for 7 because we have 7 hot dogs and y is the symbol used for hot dogs. This equation would now be 7(-3/4x+3.75) because hotdog=y=-3/4x+3.75, so hotdog=-3/4+3.75 and we have 7 hot dogs so you just multiply that by 7

Your answer would be 686in

Step-by-step explanation:

I say this because were suposed to use the formula V= l x w x h nd when applied it looks like this 686in = 14 x 14 x 3.5. Your welcome

The Volume of Pizza box is 686 inches³.

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Given:

We have pizza box of shape Cuboid

length = 14 inches

width = 14 inches

height= 3.5 inches

So, Volume of box

= l x w x h

= 14 x 14 x 3.5

= 686 inches³

Use the formula,

I = Prt

P = Principal amount = 400

I = interest = 18

r = annual rate

t = time in years = 9/12 = 3/4

so,

18 = 400*r*3/4

r = 0.06

so the annual interest rate is 0.06 or 6%

Answer:

Step-by-step explanation:

Area of the circle = πr² = π7.3² = 53.29π

Area of major sector = 53.29π(285/360) ≈ 132.54 cm²

The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.

The region bounded by the two radii and intercepted arc in a circle is called a sector .

The angle made by the radii to the center of the circle is called central angle .

if the measure of the angle is less than 180 degree then it is called minor sector and if the angle is more than 180 degree , it is called Major Sector.

It is given that

The radii of the circle is 7.3 cm

The angle subtended by the major sector at the center is 285 degree.

The area of the sector is given by

= ([tex]\rm \theta[/tex] / 360) * Area of the circle

Area of the circle is πr²

Area of the sector = ( 285 / 360) * (22/7) * (7.3)²

Area of the sector is 132.5 sq.cm

Therefore , The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.

Answer: B. G(x)=3f(x)

Step-by-step explanation: hope this helped :)

The equation that represents the graph of the function g(x) is g(x) = 3f(x)

The equation of the function f(x) is given as:

f(x) = x^2

The function g(x) is compressed horizontally by a factor of 3, to get the function g(x)

This means that:

g(x) = kf(x)

Where k = 3.

So, we have:

g(x) = 3f(x)

Hence, the equation that represents the function g(x) is g(x) = 3f(x)
