Answer:

2x=100 2*50=100 the answer correct 50

Answer:

The correct answer is B: XY=4 cm

Step-by-step explanation:

This is correct because the triangles are both leaning in the same direction so the sides are congruent as stated. Congruent, means that they are equal to each other in other words symmetrical. Because of this, they are the same triangle so where 4 is on the first triangle, it will appear on the same side on the other triangle. This means the answer is B. XY = 4 cm

Answer:

The second one

Step-by-step explanation:

It cant be the first because YZ=4cm

cant be the third because m∠Y= 50°

cant be the forth one because m∠Z= 70°

so, it has to be the second one because XY≅AB

so, if AB=4cm then XY=4cm

Answer:

15.8

Step-by-step explanation:

Well if you had to round to the nearest tenth then 12.896 would be 12.9 and 2.93 would be 2.9. The reason is if it is below 5 then you would round down if it is more than 5 then round up. Then add the two numbers which are 12.9+2.9=15.8

Hope it helps. Sorry if it does not!

Answer: 39.3 inches

Step-by-step explanation:

Let x represent the length of base of ramp.

We have been given that a skateboarding ramp is 12 in high and rises at an angle of 17 degrees. We are asked to find the base of the skateboard.

The height of ramp, the base of ramp and angle of elevation make a right triangle with ground, where, 12 inch is opposite side and base of ramp is adjacent side of angle of elevation.

Therefore, the base of ramp is 39.3 inches long.

Answer:

(x+2)(x-5)

Step-by-step explanation:

Given the expression X^2−3x−10, we are to factorize it;

On factorizing;

= x² - 5x + 2x - 10

= x(x-5) + 2(x - 5)

= (x+2)(x-5)

Hence the factored form of the expression is (x+2)(x-5)

Answer:

9 out of 10

Step-by-step explanation:

90 percent chance simply means 90÷100

Which is 9 out of 10

Answer:

yes

Step-by-step explanation:

y=4 is a horizontal line which crosses the y-axis at 4; slope is zero

x=8 is a vertical line which crosses the x-axis at 8; slope is undefined

You are correct great job! I believe you did

1/4 × 1/9 = 1/36 If so thats exactly the right method!

Answer: t= 7

Step-by-step explanation:

Take 56 divided by 8 and you get the remainder of 7. So t must equal 7.

Answer:

area of circle F = 9 pi

Step-by-step explanation:

An interesting problem, combining geometry and algebra.

It has not been indicated, but it will be assumed that GH is a tangent to the circle F, hence the tangent-secant theorem from point H applies.

Produce HF to point E on the circumference such that EJ forms a diameter of circle F.

By the tangent-secant theorem,

HG^2 = HJ*HE

Substitute given values,

(x+2)^2 = 2*(2*(2x-1)+2)

Expand algebraically

x^2+4x+4 = 2(4x-2+2)

x^2+4x+4 = 8x

x^2-4x+4 = 0

Factor

(x-2)^2 = 0

=>

x=2

Substitute x=2 into radius FG = 2(x)-1 = 3

Therefore area of circle F

= pi r^2

= pi (3)^2

= 9 pi

Answer:

A                1 and 2

Step-by-step explanation:

Answer:

12 π sq. in.  

Step-by-step explanation:

Circumference c = 2πr

Arc Length s = [tex](\frac{0^0}{360^0})[/tex] (2πr)

s = [tex](\frac{120}{360})[/tex] * 2π * 6 = 4π = 12

Mark me as brainliest!!

6 + (-10) = -4

-7 + -8= -15

Step-by-step explanation:

A linear equation in two variables can be described as a linear relationship between x and y, that is, two variables in which the value of one of them (usually y) depends on the value of the other one (usually x). In this case, x is the independent variable, and y depends on it, so y is called the dependent variable

Answer:

x^4 - x^3 + 2x -6

Step-by-step explanation:

(f-g)(x) = x^4-3x^2+5x-7 - ( x^3-3x^2+3x-1 ) = x^4 - 3x^2+5x-7 - x^3 + 3x^2 - 3x + 1  = x^4 - x^3 + 2x -6

Step-by-step explanation:

x^4-3x^2+5x-7 – x^3-3x^2+3x-1

x^4-3x^2+5x-7 – x^3+3x^2-3x+1

x^4-3x^2+3x^2-3x +5x -x^3 -7+1

x^4+2x -x^3 -6

x^4-x^3+2x-6

Answer: [tex]\dfrac{4}{5}\ m[/tex]

Step-by-step explanation:

Given

The length of one piece of string is [tex]\frac{1}{5}\ m[/tex]

So, the length of 4 pieces is the addition of four-piece length.

[tex]\Rightarrow L=\dfrac{1}{5}+\dfrac{1}{5}+\dfrac{1}{5}+\dfrac{1}{5}\\\\\Rightarrow L=4\times \dfrac{1}{5}\\\\\Rightarrow L=\dfrac{4}{5}\ m[/tex]

Answer:

Step-by-step explanation:

2 root ( 5,0)

y intercept (0,5)

Answer:

90 + 29 + x = 180

119 + x = 180

-119        -119

X = 61  degrees

A triangle will always equal 180 degrees.

Given that there is a right triangle it is 90 degrees, also given that 29 degrees is there we add those and add x (the unknown degree) to equal 180 degrees.

Answer:

T = 4.0 s

Step-by-step explanation:

The period of a simple pendulum is given by

[tex]period = 2\pi \sqrt{ \frac{l}{g} } [/tex]

where l = length of the pendulum

= 4 m

g = acceleration due to gravity

= 9.8 m/s^2

[tex]period = 2\pi \sqrt{ \frac{(4 \: m)}{(9.8 \: \frac{m}{ {s}^{2} } )} } = 4.0 \: s[/tex]
