The long side of a rectangle is 4 times the side of a square of length 3. What is the length of the side of the rectangle?

Answer:

180 degrees

Step-by-step explanation:

if it was to be 270 degrees the the image should be formed opposite to triangle A'B'C'

If it was to be 360 degrees the image should be back to original triangle and if it was 90 degrees the triangle should be triangle A'B'C'

Answer:

468 square feet; Option C

Step-by-step explanation:

We can see that the base of this triangular prism has dimensions 15 feet by 10 feet, so for starters let us compute the area of this base:

Area ⇒ 15 * 10 = 150 ft^2

Now the rectangular surface next to this base, has dimensions 9 feet by 10 feet, provided that 9 feet is a uniform height of the triangular prism:

Area ⇒ 9 * 10 = 90 ft^2

This third rectangle is provided with one dimensions, of 10 feet. If we were to imagine what part of the 3-d shape is is, it would in fact be the slanted top. To find the second dimension, you would imagine it to be 12 feet. Using that, the area of this rectangle is thus ⇒ 10 * 12 = 120 ft^2

Now the two triangles at the corners each have an area of ⇒ 1/2 * base * height = 1/2 * 12 * 9 = 6 * 9 = 54 ft^2, so they have a total area of ⇒ 108 ft^2

This means the surface area of the right, triangular prism is:

150 + 90 + 120 + 108 = Answer: 468 square feet

Answer:

V =165 ft^3

Step-by-step explanation:

V = Bh  Where B is the area of the base and h is the height

B is the area of the triangular base

B = 1/2 (5) *6

B = 15 ft^2

V = 15 * 11

V =165 ft^3

Answer:

Answer:

The area of the label is 36*pi in²

Step-by-step explanation:

A can of soup has a shape of a cylinder, therefore it's volume is equal to:

Volume = pi*r²*h

We need to use the formula above to find the radius of the base, because we need to calculate the lateral area of the cylinder, which is given by:

Lateral area = 2*pi*r*h

Applying the data from the problem we have:

54*pi = pi*r²*6

pi*r²*6 = 54*pi

r² = 54*pi/(pi*6)

r² = 54/6 = 9

r = sqrt(9) = 3 in

Therefore the lateral area is:

lateral area = 2*pi*(3)*(6) = 36*pi in²

Answer:

18π in ²

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cylinder.

Given data

volume v = 54 π in³

Height h = 6 in

In this problem we are considering the surface area of the cylinder

(not the total though ) but the curved surface area

Let us solve for the radius of the shape

Volume = πr²h

54π= π*r²*6

54/6= r²

r²= 9

r= √ 9

r= 3in

Area of curved surface = 2πrh

Area = 2πrh

Area =2π*3*6

Area = 18π in ²

Answer:

The greatest number of arrangements she can make would be that she uses 4 groups of 5 daisies and 4 groups of 4 roses.

The greatest number of arrangements is 4, and each group has 5 daises and 4 roses.

The biggest positive integer that divides both numbers and is a divisor of both is known as the greatest common divisor of two integers.

Given that, Amanda has 20 daises and 16 roses.

The number of arrangements that can be made using 20 daises and 16 roses is the greatest number that can divide both the numbers 20 and 16.

The greatest number that can divide both 20 and 16 is 4.

Hence, 4 groups of arrangements can be made.

The number of daises in a group is:

20/4

= 5

The number of roses in a group is:

16/4

= 4

Hence, the greatest number of arrangements is 4, and each group has 5 daises and 4 roses.

Answer:

B. X > 0

Step-by-step explanation:

It is X > 0, because the circle is empty, which means that X cannot be 0, which allows s to eliminate C and D as an answer. The arrow shows that X is greater than 0. Therefore, you can eliminate A as an answer, leaving us with B. X > 0

Answer: 53,130 possible combinations

Step-by-step explanation:

First, we want to find how much is the 20% of 25.

This is:

N = (20%/100%)*25 = 5.

So 5 students out of 25 are selected.

When we want to calculate the number of combinations of N elements it a group of K elements, we have:

[tex]C = \frac{N!}{(N - K)!*K!}[/tex]

Here N = 25, and K = 5

[tex]C = \frac{25!}{20!*5!} = \frac{25*24*23*22*21}{5*4*3*2*1} = 53,130[/tex]

so we have 53,130 combinations.

The solutions to the quadratic equation [tex]4(x + 2)^2 = 36[/tex] are as x = -5 and x = 1.

Suppose that we've a function y = f(x) such that f(x) is quadratic.

When y = 0, then the values of x for which f(x) = 0 is called solution of quadratic equation f(x) = 0

This solution gives values of x, and when we plot x and f(x), we'd see that the graph intersects the x-axis at its solution points.

We have the given quadratic equation

[tex]4(x + 2)^2 = 36[/tex]

solving for x

[tex]4(x + 2)^2 = 36\\\\(x + 2)^2 = 36/4\\\\(x + 2)^2 = 9\\\\(x + 2)^2 = 3^2\\\\(x + 2) = 3\\\\x = 1\\or \\\\x + 2 = -3\\\\x = -5[/tex]

Answer:

You did not write the options, but let's solve it in a general way.

f(x) and g(x) are quadratic functions, this means that:

f(x) = a*x^2 + b*x + c

g(x) = d*x^2 + e*x + f

now, (g + f)(x) is a linear function that goes trough the points (-3, 4), (0,1 ) and (1,0)

(g + f)(x) = s*x + k

We can find the slope of this linear function as:

S = (y2 - y1)/(x2 - x1)

i will use the first two points.

S = (1 - 4)/(0 - (-3) = -3/3 = -1

so we have: ( f + h)(x) = -1*x + k

and we can find k using one of the points, for example (0, 1)

1 = -1*0 + k

b = 1.

so we have: (f + g)(x) = -1*x + 1.

Now, (f+g)(x) = (a + d)*x^2 + (b + e)*x + (c + f) = -1*x + 1.

So we must have that:

a = -d

b + e = -1

c + f = 1.

4 weeks, Jose and Martin will have the same amount of money in 4 weeks which is $150 each

Step-by-step explanation:

Jose:

y = -25x +250

Martin:

y=30x+30

Substitute x= 6 into the two equations

Jose:

y = -25(6) + 250

= -150+250

y = 100

Martin:

y = 30(6) +30

=180+30

y = 2100

Substitute x=4 into the two equations

Jose:

y = -25(4) + 250

=-100+250

y = 150

Martin:

y = 30(4) + 30

=120+30

y = 150

We will use 2/3 of the  gas in the tank

That will leave us 1/4

Mathematically

Subtract this from the amount in the tank

3/4 -1/2

3/4 -2/4 = 1/4

Answer:

1330.808 euros

Step-by-step explanation:

Let's first calculate the total amount of kilograms,

for the first 60, we have to:

50 kg

4 hg = 0.5 kg

60 dag = 0.6

5 g = 0.005 kg

adding: 50 + 0.5 +0.6 + 0.005 = 51.105 kg per tree, but they are 60

51.105 * 60 = 3066.3

now for the other 20:

53 kg

2 hg = 0.2 kg

16 dag = 0.16

5 g = 0.005

adding: 53 + 0.2 +0.16 + 0.005 = 53.365 kg per tree, but they are 20

53,365 * 20 = 1067.3

in total it would be: 3066.3 + 1067.3 = 4133.6

they tell us that 1/5 is the quantity in liters:

4133.6 * 1/5 = 826.72 liters

so to calculate the earnings it would be:

2.65 * 826.72 - 860 = 1330.808

which means that in net earnings are 1330.808 euross
