Answer: Choice A

[tex]\angle F \text{ and } \angle R[/tex]

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

Explanation:

The order of the lettering of GFHE and TRQS is important.

This is because the letters of each pair up together

Because the figures are similar, the paired angles are congruent. So we can say [tex]\angle F \cong \angle R[/tex]

In terms of a visual confirmation, angles F and R are located in the bottom left corner. So this helps back up the answer. Though keep in mind that often the diagrams are misleading and not drawn to scale. So we can't always rely solely on the diagram.

The value of k is -11.

Given

The equation 3√(x-k)-2=10 has a solution of x = 5.

To find the value of k put x = 5 in the equation then solve for the value of k.

Therefore,

The value of k is;

[tex]\rm 3\sqrt{x-k}-2=10[/tex]

Substitute x = 5 in the equation

[tex]\rm 3\sqrt{5-k}-2=10\\\\\rm 3\sqrt{5-k}=10+2\\\\\rm 3\sqrt{5-k}=12\\\\\rm \sqrt{5-k}=\dfrac{12}{3}\\\\ \sqrt{5-k}=4\\\\[/tex]

Squaring on both sides

[tex]\rm \sqrt{5-k}=\dfrac{12}{3}\\\\5-k=16\\\\-k = 16-5\\\\-k=11\\\\k=-11[/tex]

Hence, the value of k is -11.

Answer:

180 hours per week

Step-by-step explanation:

To find this answer, multiply all of the factors to get your answer

In this scenario, that would be 45x4

When you multiply this out, you get 180 hours

So your answer is 180 hours per week!

(By the way whoever created this problem doesn’t know simple time because there are only 24 hours in a day!)

Hope this helps!

Answer:

Step-by-step explanation: Let's say you have 2 supplementary angles, x and y

So x + y = 180

if x is 79.6 degrees less than the measure of a supplementary angle, then x = y - 79.6

Putting this into our x + y = 180 equation, we get

(y - 79.6) + y = 180

2y - 79.6 = 180

2y = 180 + 79.6

2y = 259.6

y = 259.6/2 = 129.8 degrees.

so x = 129.8 - 79.6 = 50.2 degrees.

See if it worked. x = 129.8 degrees,  y = 50.2 degrees,    x + y = 180 so we found the correct two angles!

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

The formula for calculating the sum of interior angles is:

(n - 2) x 180°  (where n is the number of sides)

interior angle of a polygon = sum of interior angles ÷ number of sides

165 = [ (n - 2) x 180° ] ÷ n

Mulitply both sides by n:             165n = (n - 2) x 180°

Expand brackets:                         165n = 180n - 360

Add 360 to both sides:    165n + 360 = 180n

Subtract 165n from both sides:   360 = 15n

Divide both sides by 15:                 24 = n

Therefore, the number of sides = 24

Answer:

The distance each bus travels is given as d=tr where

- d is distance bus travels

- t is a time bus travels

- r is the speed of the bus

:

Distance first bus travels for 4 hours is d1=4r.

Distance other bus travels for 4 hours is d2=4(r+12).

:

The total distance between them is 480 miles and since they go in opposite directions this distance is the sum of distances each bus travels.

:

d1+d2=480

4r+4(r+12)=480

4r+4r+48=480

8r+48=480

8r=432

r=432/8

r=54 mph, this is a speed of the first bus

:

r+12=66 mph, this is the speed of the second bus

Answer:

Step-by-step explanation:

The equation for projectile motion in feet is [tex]h(t)=-16t^2+v_0t+h_0[/tex] where [tex]v_0[/tex] is the initial velocity in ft/s and [tex]h_0[/tex] is the initial height in feet.

We are given that the initial upward velocity is [tex]v_0=150ft/sec[/tex] and the initial height is [tex]h_0=35ft[/tex]. Thus, plugging these values into our equation, we get [tex]h(t)=-16t^2+150t+35[/tex] as our equation for the situation.

The firework will land, assuming it doesn't explode, when [tex]h(t)=0[/tex], thus:

[tex]h(t)=-16t^2+150t+35\\\\0=-16t^2+150t+35\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-150\pm\sqrt{150^2-4(-16)(35)}}{2(-16)}\\ \\t=\frac{-150\pm\sqrt{22500+2240}}{-32}\\\\t=\frac{-150\pm\sqrt{24740}}{-32}\\\\t=\frac{-150\pm2\sqrt{6185}}{-32}\\ \\t=\frac{75\pm\sqrt{6185}}{16}\\\\t_1\approx-0.2\\\\t_2\approx9.6[/tex]

Since time can't be negative, then the firework will land after 9.6 seconds, assuming it doesn't explode at the time of landing.

Answer:

you need to place the centre of your protractor on the vertex of the two lines.  

Step-by-step explanation:

Once you place it on the vertex, since the horizontal line is on the left side of the protractor, you start measuring the angle from the left side.

You keep on measuring the point where 2nd line overlaps some angle marking on the protractor.

For the bottom left angle, you need to place the protractor diagonally on the right most line as the horizontal line and then measure the angle.
