If p is inversely proportional to the square of q, and p is 30 when q is 10 determine p when q is equal to 5
Answer:
The value of p = 120 when q = 5
Step-by-step explanation:
We know that if y varies inversely with x, we get the equation
y ∝ 1/x
y = k/x
k = yx
where 'k' is called the constant of proportionality.
In our case,
If p is inversely proportional to the square of q, then
p ∝ 1/q²
p = k/q²
k = pq²
As p is 30 when q is 10, so
substituting p = 30 and q = 10
k = (30) (10)²
k = (30)(100)
k = 3000
Now,
Determining the value of p when q = 5
Using the equation
p = k/q²
now substituting k = 3000 and q = 5
p = 3000 / (5)²
p = 3000/25
p = 120
Therefore, the value of p = 120 when q = 5
The triangle on the left is a scale drawing of the real object on the right. The scale drawing was made using a scale factor of 2.
How does the scale factor affect the angle measures in the scale drawing?
Answer:
It doesn't
Step-by-step explanation:
When a shape is scaled up or down, the angles don't change.
It's easier to picture using a square. Like no matter how long the sides are, the angles are all 90 degrees. Its the same with every shape though- as long as it's evenly resized.

What is the area of the regular hexagon ABCDEF? Explain your reasoning.
Answer:
2340 units²
Step-by-step explanation:
The easiest way to solve for the area of the hexagon is to find the area of the rectangle and subtracting the area of the triangles from it.
First, find the area of the rectangle:
A(rectangle) = (15 + 30 + 15)(26 + 26)
A(rectangle) = (60)(52)
A(rectangle) = 3120
Next, find the area of the 4 triangles:
A(triangles) = 1/2(15)(26) · 4
A(triangles) = 195 · 4
A(triangles) = 780
Finally, subtract the two areas to find the area of the hexagon:
A(hexagon) = 3120 - 780
A(hexagon) = 2340
Based on the information given the area of hexagon is 2340.
Area of hexagon:First step is to find the area of the rectangle:
Area of rectangle= (15 + 30 + 15)(26 + 26)
Area of rectangle=60×52
Area of rectangle= 3120
Second step is to find the area of the 4 triangles:
Area of rectangle =[1/2(15)(26)]×4
Area of rectangle= 195 × 4
Area of rectangle= 780
Third step is to find the area of hexagon:
Area of hexagon= 3120 - 780
Area of hexagon=2340
Inconclusion the area of hexagon is 2340.

2x - 7y = 13
3x + y = 8
are they being multiplied or added or subtracted?
Answer:
(3, -1)
Step-by-step explanation:
3x +y = 8
-3x =-3x
Y=-3x +8 Substitute into 1st equation y=-3x+8
2x-7(8-3x+8)= 13 -3(3) + 8
2x-56+21x= 13 -9 +8
23x-56 =13 y = -1
+56= +56
23x = 69
23 23
x = 3

16 and 22.5
Step-by-step explanation:
To find the mean, simply add all the numbers together and divide by the amount of values that are present in the data set.
1.) (20 + 15 + 19 + 16 + 10)/5 = 16
2.) (19 + 23 + 11 + 30 + 27 + 27 + 22 + 26 + 16 + 24)/10 = 22.5

Andrew writes 1/7 of a page in 1/7 of a minute. How much time, in minutes, does it take him to write a full page? Type your answer as a fraction. If it is improper, change it to a mixed number. Do not include "minutes" in your answer.
Answer: 1
Step-by-step explanation:
From the question, we are informed that Andrew writes 1/7 of a page in 1/7 of a minute. The number of minutes that would take for him to write a full page would be:
= 1/7 ÷ 1/7
= 1/7 × 7/1
= 7/7
= 1 minutes

ABC and ACD are triangles
a) Show that AC=11.4cm, correct to 3 significant figures.
Answer: 17² + 13² - 2 × 17 × 13 × COS(42) = 11.38112416
AC = 11.38112416 correct to 3 significant figures = 11.4cm
Thanks for helping me on part B :)
Step-by-step explanation:
The length of AC is 11.4 centimeters and the length of BC is 30.9 centimeters.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a triangle.
ΔABC and ΔACD are two triangles.
A. The value of AC will be
Using the cosine rule,
AC² = AD² + AC² - 2 × AD × AC × cos D
AC² = 17² + 13² - 2 × 17 × 13 × cos 42
AC² = 289 + 169 - 328.47
AC² = 129.52
AC = 11.4 cm
B. The value of BC will be
Using the sine rule,
[tex]\rm \dfrac{BC}{sin A} = \dfrac{CA}{sin B} = \dfrac{AB}{sin C}\\\\\dfrac{BC}{sin 76} = \dfrac{11.4}{sin 21 } =\dfrac{AB}{sin 83 }[/tex]
From the first 2, we have
[tex]\rm \dfrac{BC}{sin 76} = \dfrac{11.4}{sin 21 } \\\\B \ C \ \ = 30.9[/tex]
Thus, the length of AC is 11.4 centimeters and the length of BC is 30.9 centimeters.

Erica paid $75 3.95 for dance classes. She paid $123.95 for each week she was enrolled in the classes after using a coupon that gave her $45 off the price per week. What is w, the number of weeks Erica was enrolled in dance classes?
Answer:
The first one, 14 weeks of dance classes.
Step-by-step explanation:
She paid $753.95 as a total for all of the classes, not just one week. She paid her registration free, which you subtract from 753.95 to get 630.00. She pays 45 per week, so you divide 630 by 45 to get the amount of weeks she attended dance classes, or 14 weeks.
