Answer:

x = -8

Step-by-step explanation:

The triangle is isosceles so the two angles are equal

Equation :

65 = x + 73

Subtract 73 from both sides

-8 = x

Check:

65 = -8 + 73

65 = 65

Answer:

it's base times height or it can be the width of the shape

Answer:

Using Pythagoras theorem we can find the missing length.

5^2 + 13^2

25 + 169 = 194

√194 = 13.9283882772 = around 13

Answer:

A

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12 → A

Diameter = 2 times the radius or

D = 2r

Solve for r and substitute 10 for D

Answer:

5 inches.

Step-by-step explanation:

Divide the diameter by two to get the radius.

Answer:

Step-by-step explanation:

volume=πr^2h

461.58=3.14*r^2*12

461.58=37.68*r^2

461.58/37.68=r^2

12.25=r^2

[tex]\sqrt{12.25[/tex]=r

3.5=r

diameter=radius*2

=3.5*2

=7 in.

Answer:

Step-by-step explanation:

volume of a cylinder= base area times height or pie (r) squared * (h)

461.58=pie r squared h

461.58=3.14*r squared *12

461.58=37.68*r squared

Answer:

254 inches squared

Step-by-step explanation:

Hi there!

[tex]A=\pi r^2[/tex] where r is the radius of the circle

The radius is equal to half the diameter. Given that the diameter is 18 inches, we know that the radius of the circular plate is 9 inches. Plug this into the equation:

[tex]A=\pi (9)^2\\A=81\pi \\A=254[/tex]

Therefore, the area of the plate is approximately 254 inches squared.

If this is not an answer choice, the question may have been asking for the radius of the circle rather than the area.

Answer:

143.7cm^2

Step-by-step explanation:

Given data

Volume= 576cm^3

Radius= 8cm

The expression for the volume of cylinder is

V= πr^2h

substitute

576= 3.142*8^2*h

576= 3.142*64*h

576= 201.088h

h= 576/201.088

h=2.86cm

The formula for finding the lateral area of a right circular cylinder is:

A=2πrh

substitute

A= 2*3.142*8*2.86

A= 143.7cm^2

Hence the area is 143.7cm^2

Answer:

Step-by-step explanation:

It seems to me that you are being asked for what values of x does f(x) + g(x) = 0. Which means that you need to add them together, combine like terms if possible, and then factor. Adding them together gives you

[tex]x^2+6x+4=0[/tex]  This doesn't factor to integer solutions, so we will use the quadratic formula to factor it. The quadratic formula is as follows:

[tex]x=\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex] For us, a = 1, b = 6, c = 4. Filling in accordingly:

[tex]x=\frac{-6+-\sqrt{36-4(1)(4)} }{2}[/tex] and simplifying a bit:

[tex]x=\frac{-6+-\sqrt{20} }{2}[/tex]  The square root of 20 can be simplified down to 2√5, so plugging that in gives us:

[tex]x=\frac{-6+-2\sqrt{5} }{2}[/tex] and then reducing everything down to its lowest terms:

x = -3 ± √5. Those are irrational numbers but they are the numbers that make that addition o to 0.

Explanation:

I'm assuming 7/5 is the scale factor. If so, notice how 7/5 = 1.4 which is larger than 1.

The scale factor being larger than 1 means we have an enlargement.

The image is going to be larger compared to the preimage.

The preimage rectangle is 12 in by 6 in. Multiply each dimension by 1.4 to get 12*1.4 = 16.8 and 6*1.4 = 8.4

The image rectangle is 16.8 inches by 8.4 inches

Answer:

This is an enlargement. The dimensions of the scaled rectangle is 16.8 inches by 8.4 inches.

Step-by-step explanation:

This is a dilation.

A dilation makes a figure larger or smaller.

In this case, the scale factor is an enlargement; the figure will be larger.

The figure will be larger because the scale factor, 7/5, is larger than one (1).

If the scale factor were smaller than one (1), it would be a reduction.

In dilations, a scale factor is how much larger the image will be.

In other words, multiply the side lengths by the scale factor.

The original rectangle has a length of 12 inches and a width of 6 inches.

[tex]12*7/5=84/5[/tex]

[tex]6*7/5=42/5[/tex]

It will be more convenient to change the products, which are fractions, to decimals.

[tex]84/5=16.8[/tex]

[tex]42/5=8.4[/tex]

Therefore, the dimensions of the scale rectangle is 16.8 inches by 8.4 inches.
