Which descriptions from the list below accurately describe the relationship between AQRS and ATUV? Check all that apply. 284 -28 12 12 76" 176 176 1764 6 V Q A. Same sides B. Same size C. Similar D. Congruent
Answer:
All A to D
Step-by-step explanation:
The attachment completes the question
From the attachment,
it can be seen that QRS and TUV are of the same i.e. trianglesAlso, from the attachment, the sides of each are:
[tex]RQ = UT = 22[/tex]
[tex]QS = TV = 30[/tex]
[tex]RS = UV = 23[/tex]
And the angles are:
[tex]\angle Q = \angle T = 50[/tex]
[tex]\angle R = \angle U = 83[/tex]
[tex]\angle S = \angle V = 47[/tex]
The above show that QRS and TUV are:
similarsame sidesand they are congruentFind an
equation for the perpendicular bisector of the line segment
whose endpoints (7,9) and (-1,3).
are
Step-by-step explanation:
A perpendicular bisector is a line that cuts a line segment connecting two points exactly in half at a 90 degree angle. To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.

(-11/6) + m= -2/9
SOLVE FOR M
Answer:
29/18
Step-by-step explanation:
Add -11/6 to both sides of the equation
m=-2/9+11/6 = -4/18+33/18=29/18

Rebecca runs a quarter-mile each week. In each of the last 6 weeks her time has improved (decreased) by 2%, and she can now run a quarter-mile in 66 seconds. What was her time six weeks ago?
Answer:
75 seconds
Step-by-step explanation:
Here, we want to get her time 6 weeks ago.
We shall have an exponential model to link this all up
The exponential model would look like;
y = I(1 - r)^n
where y is the present time
I is the initial time she started with which we are calculating
r is the rate of change which is 2% = 2/100 = 0.02
n is the week number which is 6 in this case
So we have;
66 = I(1 - 0.02)^6
66 = I(0.98)^6
I = 66/0.8858
I = 74.5 seconds
This is approximately 75 seconds
Her time 6 weeks ago is 75 seconds

On Monday, the low temperature outside was 32 degrees above zero. On Christmas, it was 5 degrees below zero. What is the difference in the two temperatures?
Answer:
Difference in temperatures = 37 degree
Step-by-step explanation:
Given:
Temperature above zero = 32 degree
Temperature below zero = -5 degree
Find:
Difference in temperatures
Computation:
Difference in temperatures = Temperature above zero - Temperature below zero
Difference in temperatures = 32 - (-5)
Difference in temperatures = 37 degree

There are 15 plates in a kitchen cabinet. The diameter of each plate is either 7in or 12in. The diameter of all 15 plates combined is 140in. Which system of equations can be used to find the number of 7in plates, x , and the number of 12in plates, y , that are in the cabinet?
Answer:
Number of 7 inch plate = 8
Number of 12 inch plate = 7
Step-by-step explanation:
There are 15 plates in a kitchen cabinet. The diameter of each plate is either 7in or 12in. The diameter of all 15 plates combined is 140in. Which system of equations can be used to find the number of 7in plates, x , and the number of 12in plates, y , that are in the cabinet?
Given that :
Total Number of plates = 15
Diameter of each plate : 7 in or 12 in
Diameter of all 15 plates = 140 in
Let number of 7 in and 12 in diameter plates = x and y respectively ;
x + y = 15 - - (1)
7x + 12y = 140 - - - (2)
x = 15 - y
Substitute x = 15 - y in (2)
7(15 - y) + 12y = 140
105 - 7y + 12y = 140
105 + 5y = 140
5y = 140 - 105
5y = 35
y = 7
From x = 15 - y
x = 15 - 7
x = 8
Number of 7 inch plate = 8
Number of 12 inch plate = 7

In ΔBCD, \text{m}\angle B = (4x-14)^{\circ}m∠B=(4x−14) ∘ , \text{m}\angle C = (x-1)^{\circ}m∠C=(x−1) ∘ , and \text{m}\angle D = (6x+8)^{\circ}m∠D=(6x+8) ∘ . What is the value of x?X?
Answer:
x = 17Step-by-step explanation:
The sum of angle in the triangle BCD is 180 degrees
Given;
<B = 4x -14
<C = x - 1
<D = 6x + 8
Required
Find x
Since <B + <C + <D = 180, hence;
4x - 14 + x - 1 + 6x + 8 = 180
11x -7 = 180
11x = 180+7
11x = 187
x = 187/11
x = 17
Hence the value of x is 17
I have finals next week and I’m stressing out-
Any advice?
Answer:
Hmmm.... well for one thing I would at least review a few things, just so you can feel a bit more confident in your work, then if that doesn't work you can review more or get your mind off stuff by going somewhere fun. SLEEP It's kinda hard yes but still staying up all night studying and worrying isn't going to do anything but make you sloppy. Make sure you are well fed before said test. Mainly just don't strain yourself too much because like I said before it'll make it harder in class.
I'm sure you've heard this before but yeah it works if you really take it to heart

3.2 geometry worksheet
Answer/Step-by-step explanation:
9. 17x = 16x + 5 (alternate exterior angle)
17x - 16x = 5
x = 5
Measure of bolded angle = 17x = 17 * 5 = 85
10. 21x - 6 = 20x (corresponding angels)
21x - 20x = 6
x = 6
Measure of bolded angle = 20x = 20(6) = 120
11. (x + 95) + (x + 105) = 180 (linear pair angles)
2x + 200 = 180
2x = 180 - 200
2x = -20
Divide both sides by 2
x = -10
Measure of bolded angle = x + 105 = -17 + 105 = 88°
12. 12x - 4 = 11x + 3 (vertical angles)
Collect like terms
12x - 11x = 4 + 3
x = 7
Measure of bolded angle = 11x + 3 = 77 + 3 = 80°

A function is represented by the graph.
Complete the statement by selecting from the drop-down menu.
The y-intercept of the function y=−2x+8 is
Choose... greater than less than or equal to
the y-intercept of the function represented in the graph.
Answer:
equal to
Step-by-step explanation:
The y intercept is when x = 0.
In the function y=-2x+8, when x=0, y=8.
In the graph, when x=0, y=8. You can see on the x axis 0 is in the middle, and if you move up the y axis, you see the line intersects y=8.
Thus both have the same y intercepts of 8.

Tim bought a video game console and games for $350. The video game console cost $200. Each game cost $25. How many games did Tim purchase?
Answer:
Tim purchased 6 video games.
Step-by-step explanation:
Let's set the number of games Time purchased as x.
Due to each game costing $25, the total amount of money used on buying games would be ($25)x.
Hence, as the total amount of money used to buy both the console and the video games would be $350, the equation can be set as:
[tex]\$25x + \$200 = \$350[/tex]
[tex]\$25x = \$(350 - 200)[/tex]
[tex]x = \frac{\$150}{\$25}[/tex]
[tex]x = 6[/tex]
Therefore, Tim purchased 6 video games.
Hope this helped!
What is the base area.
Answer:
Area of the base is 10.5 cm².
Step-by-step explanation:
Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases
Vertical height = 6 cm
Volume = 63 cm³
From the formula,
63 = Area of the triangular base × 6
Area of the base = [tex]\frac{63}{6}[/tex]
= 10.5 cm²
Therefore, area of the base is 10.5 cm².
