please Help with my area math question. ​ I don't remember how to do it. multiply or add? and what is the answer to this?

Step-by-step explanation:

[tex]\angle 3[/tex] and [tex]\angle 16[/tex] are alternate exterior angles so they are equal to each other, which means

[tex]5x - 30 = 3x + 10 \Rightarrow x = 20[/tex]

Solving for the measure of [tex]\angle 16[/tex], we get

[tex]m\angle 16 = 5(20) - 30 = 70°[/tex]

Since [tex]\angle 12[/tex] and [tex]\angle 16[/tex] are supplementary,

[tex]m\angle 12 = 180° - 70° = 110°[/tex]

Answer:

[tex]\frac56[/tex] cups

Step-by-step explanation:

The serving size is proportional to the amount of milk used, so we have

[tex]\frac{2/3}{4/5}=\frac x1[/tex]

where [tex]x[/tex] is the amount of milk needed for 1 serving. The right side is simply [tex]x[/tex]. We now simplify

[tex]x=\frac23\cdot\frac54=\frac{10}{12}=\frac56[/tex]

Therefore [tex]\frac56[/tex] cups of milk are needed for 1 serving.

Answer:

150°

Step-by-step explanation:

Sum of all angles in a hexagon = 720°

90° + 120° + 150° + 145° + 65 ° = 670°

720° - 570° = t

t = 150°

Answer:

a= $10.00

Step-by-step explanation:

It's very simple. Move /8 to the other side of the equation. It should give you $1.25 x 8. Solve the multiplication and you should get $10.00.

If I didn't make my explanation clear enough, please comment. I sometimes don't even explain myself very well.

Answer:

a = 10

Step-by-step explanation:

a/8 = 1.25

multiply both sides by 8 to isolate a.

(8)(a/8) = 1.25(8)

which gives you

a = 1.25(8)

which simplifies to

a = 10

Answer:

AA

Step-by-step explanation:

See In Triangle ABC and Triangle STU

[tex]\because\begin{cases}\sf \angle A=\angle S=90° \\ \sf \angle B=\angle T=31°\end{cases}[/tex]

Hence

[tex]\sf \Delta ABC~\Delta STU(Angle-Angle)[/tex]

By AA similarity  triangle ABC is similar to triangle SUT. Therefore, option A is the correct answer.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

In the given triangle ABC, ∠C=180°-90°-31°

∠C=59°

In the given triangle SUT, ∠U=180°-90°-31°

∠U=59°

Here, ∠B=∠T (Given)

∠C=∠U (Obtained using angle sum property of a triangle)

So, by AA similarity ΔABC is similar to ΔSUT.

Therefore, option A is the correct answer.

If two triangles have two congruent sides and a congruent non included angle, then triangles are not necessarilly congruent.

Step-by-step explanation:

Find three consecutive odd integers such that the sum of the last two is 15 less than 5 times the first.

let the consecutive odd integers are :- x , x + 2 and x + 4.

According to question :-

the sum of the last two is 15 less than 5 times the first.

It means that

the sum of ( x + 2 ) and ( x + 4 ) is 15 less than 5 times the x .

( x + 2 ) + ( x + 4 ) = 5x - 15

x + 2 + x + 4 = 5x - 15

2x + 6 = 5x - 15

6 + 15 = 5x + 2x

21 = 7x

or ;

7x = 21

x = 21 / 7

x = 3

So, the consecutive odd numbers are :-

x = 3

x + 2 = 3 + 2 = 5

x + 4 = 3 + 4 = 7

=> 3 , 5 and 7

Answer:

y=2x-5

Step-by-step explanation:

By using two-points form:

y-y1/y2-y1=x-x1/x2-x1

p(x1,y1)=(4,3)

p(x2,y2)=(2,-1)

Subtitute points in formula:

y-3/-1-3=x-4/2-4

y-3/-4=x-4/-2

y-3/-2=x-4/-1

1(y-3)=2(x-4)

y-3=2x-8

y=2x-8+3

y=2x-5

Answer:

  f(7) = 154

Step-by-step explanation:

The basic idea is you put 7 where x is and do the arithmetic.

Polynomial evaluation is sometimes easier if you rewrite it to Horner form.

  f(x) = (4x -7)x +7

  f(7) = (4·7 -7)(7) +7 = 21(7) +7 = 147 +7

m = 48

Step-by-step explanation:

3/4(2/3m)=24

Multiply each side by 4/3 using the multiplication property of equality

4/3*3/4(2/3m)=24*4/3

2/3m = 32

Multiply each side by 3/2 using the multiplication property of equality

3/2*2/3m = 32*3/2

m = 48

===========================================================

Explanation:

As the graph shows, three of the four points are on the same line. That line being y = 5x. This line has slope 5 and y intercept 0.

The point not fitting this pattern is the point (5,15), so that is the final answer.

For the other three points, note that the jump from x to y coordinate is "times 5". For example, y = 5x = 5*2 = 10 for point A. In contrast, point D has a jump of "times 3" when going from x to y.

--------------

Alternatively, you can divide each y coordinate by its corresponding x coordinate.

All results are 5 so far. Choice D doesn't follow the trend and instead has y/x = 15/5 = 3. This is another way to show that choice D is the answer.
