Answer:

Step-by-step explanation:

what ur going to have two does is set up a cross multiplication equation of 150 over 3/4 = the variable X over 1 then cross multiply and u should get ur answer.

The number of miles that you can drive on one tank of gas, given the distance on 3 / 4 of a tank is 200 miles.

You drive 150 miles on 3/4 of a tank of gas. Therefore, to find out how far you can drive on one (a whole) tank of gas, you can set up a simple proportion and solve for the unknown.

If 3/4 of a tank gives you 150 miles, then 1 (or 4/4) tank would give you:

150 miles / (3/4) = X miles / (4/4)

where X is the distance you can drive on one tank of gas.

Solving gives:

150 miles * 1 = x miles * 3 / 4

200 miles = X miles

Answer:

[tex]\angle EHG = 80[/tex]

Step-by-step explanation:

Given

ABC ∼ EHG

See attachment

Required

Determine [tex]\angle EHG[/tex]

First, we calculate x in ABC

[tex]x + 2x + 60= 180[/tex]

[tex]3x + 60= 180[/tex]

[tex]3x = 120[/tex]

[tex]x = 40[/tex]

The corresponding angle to [tex]\angle EHG[/tex] is [tex]\angle ABC[/tex]

and

[tex]\angle ABC = 2x[/tex]

[tex]\angle ABC = 2 * 40[/tex]

[tex]\angle ABC = 80[/tex]

Hence:

[tex]\angle EHG = 80[/tex]

Answer:

x=4

y=2

Step-by-step explanation:

2x+2y=12

x−y=2

​In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

2x+2y=12,x−y=2

To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.

2x+2y=12,2x+2(−1)y=2×2

Simplify.

2x+2y=12,2x−2y=4

Subtract 2x−2y=4 from 2x+2y=12 by subtracting like terms on each side of the equal sign.

2x−2x+2y+2y=12−4

Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.

2y+2y=12−4

Add 2y to 2y.

4y=12−4

Add 12 to −4.

4y=8

Divide both sides by 4.

y=2

Substitute 2 for y in x−y=2. Because the resulting equation contains only one variable, you can solve for x directly.

x−2=2

Add 2 to both sides of the equation.

x=4

The system is now solved.

x=4,y=2

Correct choice is B) x=4.

answer is 4

because y=2 then you subsistute it in and then you find X

x-y=2 turns to x=y+2 then you subsistute that into x of the equation 2x+2y=12 which then is 2(y+2)+2y =12 and you should get y=2 then you grab the other equation x-2=2 and you should get x=4

The value of the f(3) is -8 or f(3)=-8 if the equation of the function f(x) = -8(3)⁰ or f(x) = -8 option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

For the function, f(x) = -8

f(x) = -8

For all values of x:

The above function can be written as follows:

f(x) = -8x⁰

PLug x = 3 in the function:

f(x) = -8(3)⁰

f(x) = -8

Thus, the value of the f(3) is -8 or f(3)=-8 if the equation of the function f(x) = -8(3)⁰ or f(x) = -8 option (C) is correct.

Answer:

B

The domain of the graph is all real numbers less than or equal to 0.

Step-by-step explanation:

just took the test

The statement for the graph will be the domain of the graph is all real numbers less than or equal to 0.

Given,

Graph of function f(x) = √-x

Here,

If there is a function f(x) = √-x , then the domain is the set of all values that x can take and the range is the set of all the values that y can take for the function to exist.

Thus, the domain of the graph is all real numbers less than or equal to 0.

Therefore option B is correct.

Answer:

a) OP:RT = 10:3

b) OQ = 15 cm

c) m<P = [tex]60^{o}[/tex]

d) m<Q = [tex]94^{o}[/tex]

Step-by-step explanation:

Given that: ΔOPQ is similar to ΔRTS

Then;

a) OP:RT = 12:3.6

                 = [tex]\frac{120}{36}[/tex]

                = [tex]\frac{10}{3}[/tex]

                = 10:3

The ratio of OP to RT is 10:3.

b) The measure of length OQ = [tex]\frac{10}{3}[/tex] x 4.5

                                 = 15 cm

c) m<P ≅ m<T

So that,

m<P = [tex]60^{o}[/tex]

d) m<Q ≅ m<S

But,

26 + 60 + m<S = 180 (sum of angles in a triangle)

86 + m<S = 180

m<S = 180 - (86)

        = [tex]94^{o}[/tex]

Thus,

m<Q = [tex]94^{o}[/tex]

10201

Step-by-step explanation:

=(101)²

=(100+1)²

={100²+2(100)(1)+1²} [(a+b)²=a²+2ab+b²]

=10000+200+1

=10201

Solution :-

Given,

We need to solve it using identities.

>> (100 + 1)^2

As we know that,

>> (a + b)^2 = a^2 + b^2 + 2ab

Here,

Using the identity we gets,

>> (100)^2 + (1)^2 + 2(100)*(1)

>> 10000 + 1 + 200

>> 10000 + 201

>> 10201

Answer:

The slope is -3.75 or -15/4.

Step-by-step explanation:

The formula for slope is the change in y over the change in x.

To do this, you subtract 7-3 to get you 4 on the bottom of the fraction and -7-8 which is -15.

So pretty much, you get -15/4. :)

PLEASE HELP!! SHOW ALL WORK FOR BRAINLIEST

Quadrilateral EFGH has vertices at E(10,4), F(16,4), G(16,10) and H(10,10). Based on the properties of the diagonals, is quadrilateral EFGH a rectangle, a rhombus, or a square?? Use the distance and slope formula to prove your conclusion. Must show all work, please

Using the distance formula

√(x2 - x1)² + (y2 - y1)²

When given vertices x1, y1, and x2, y2

We find the length of each side

For E(10,4), F(16,4)

√(16 - 10)² + (4 - 4)²

= √6²

= √36

= 6 units

F(16,4), G(16,10)

= √(16 - 16)² + (10 - 4)²

= √6²

= √36

= 6 units

G(16,10) and H(10,10)

= √(10 - 16)² + (10 - 10)²

= √-6²

= √36

= 6 units

E(10,4), and H(10,10)

It is a square because all the sides are equal
