can yall pls help me with those 3

Answer:

50 degrees

Step-by-step explanation:

The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:

Given that the triangle is a right triangle, the sum of angles will be:

(4x)°+(7x-20)°+90=180

simplifying and solving for x we get:

4x+7x-20+90=180

11x=180+20-90

11x=110

dividing both sides by 11 we get:

(11x)/11=110/11

this gives us

x=10°

Thus substituting the value of x in:

∠ACB=(7x-20)°

=(7*10-20)

=70-20

=50°

Answer: 50°

Answer:

[tex]\frac{1}{2}[/tex] [tex]x[/tex]⁸

Step-by-step explanation:

Given expression:

       [tex]\frac{6x^{10} }{12x^{2} }[/tex]  

= [tex]\frac{6}{12}[/tex]  x [tex]\frac{x^{10} }{x^{2} }[/tex]  

   As a rule of exponents;

         [tex]\frac{a^{n} }{a^{m} }[/tex]  = [tex]a^{n-m}[/tex]

So;

            =  [tex]\frac{1}{2}[/tex] x [tex]x^{10-2}[/tex]  

            = [tex]\frac{1}{2}[/tex] [tex]x[/tex]⁸

Answer:

x^2+6x+6=0

Step-by-step explanation:

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

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

x^2+4x+4=-x-2

     +x   +2=+x+2

x^2+6x+6=0

Answer:

If the graph of the line passes through the origin, it means that the graph has no y-intercept

Step-by-step explanation:

Here, we want to interpret the y-intercept of a graph that passes through the origin

If the y-intercept of a graph passes through the origin, it means that the value of the y-intercept is zero

In other words, the graph has no intercept on either the y or x axes

Answer:

I agree with Derek and disagree with  What if you want to do it the long way and use the distributive property and distribute the 2 first? You would do: 8 / (4+4) = 1.

Or does the distributive property suddenly no longer apply?

That's what I would say proves that 1 is correct.

Answer:

0.56

Step-by-step explanation:

5.6 ÷ 10

When dividing by ten, move the decimal point one position to the right:

0.56

That is your answer because you were Dividing by Ten and so the worth of that number is lowered by ten or one decimal position.

Hope this helps!

Have a nice day!

Answer:

127+(-112)=15

Step-by-step explanation:

If you subtract 112 from 127, you can find the difference. Since 112 is Mya's weight, and the total is 127, we need to find out how much weight is left over after we take away Mya's weight, which would be the cat's weight. So if you follow the expression, which is 127+(-112), you would get a sum of 15 pounds. Since this is an addition problem, the expression would be 127+(-112) instead of 127-112. I hope you understand. The difference between 127 and 112 is the cat's weight, so the cat weighs 15 pounds.

Answer:

The y-intercept in this case is 4800

Step-by-step explanation:

The equation of a line graph is ;

y = mx + c

with respect to the given equation in the question, the y-intercept in this case is 4,800

In this case the y-intercept represent the height from which the plane starts to descend

Answer:

-[tex]17^\circ F[/tex]

OR

[tex]17^\circ F[/tex] decrease in the temperature.

Step-by-step explanation:

Given that:

Temperature at the night  = [tex]12^\circ F[/tex]

Temperature in the morning = -[tex]5^\circ F[/tex]

To find:

The total difference in the temperature = ?

Solution:

Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.

Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]

Negative value in the difference indicates that there is a decrease of the quantity.

So, the answer is:

-[tex]17^\circ F[/tex]

OR

there is decrease of [tex]17^\circ F[/tex] in the temperature.

Answer:

The scale factor of the dilation is 6.

Step-by-step explanation:

Dilation of a Triangle

A dilation is a transformation that produces an image that is the same shape as the original but at a different size.

Dilating a point centered at the origin means multiplying its coordinates by a fixed scale factor k.

If point A(3,6) is dilated centered at the origin by a scale factor of 4, then its new coordinates are A'(12,24).

Triangle FGH has vertices F(−5, 0), G(0, 5), and H(5, 0).

It's known a dilation, centered at the origin, is applied to this triangle and the image has vertices F′(−30, 0), G′(0, 30), and H′(30, 0)

Comparing the coordinates F and F', the x-coordinate is scaled by a factor of (-30)/(-5)=6

Comparing the coordinates G and G', the y-coordinate is scaled by a factor of (30)/(5)=6

Comparing the coordinates H and H', the x-coordinate is scaled by a factor of (30)/(5)=6

Since all the scale factors are the same, we can conclude the scale factor of the dilation is 6.

the answer will be 6

Answer:

t < 4

Step-by-step explanation:

Reservation fee = $38

Additional fee per hour = $6.80

The history club wants to spend less than $65.20 on renting the meeting room.

t = number of hours the meeting room is rented

The inequality is

38 + 6.80t < 65.20

6.80t < 65.20 - 38

6.80t < 27.20

t < 27.20 / 6.80

t < 4

Therefore, number of hours the meeting room is rented should be less than 4 hours

Answer:

Step-by-step explanation:

letter B

Answer:

B

Step-by-step explanation:

Take the three outaide the parentheses and distribute to both terms inside the parentheses. You would then get 3x+15= 15

subtract 15 from the left and right.

3x=0

Which means that x=0/3

So x=0
