Answer:
21.2Step-by-step explanation:
[tex]x\times(x+ 28) = 20\times (20+32)\\\\x^2+28x-1040=0\\\\\ x=\dfrac{-28\pm\sqrt{28^2-4\cdot1\cdot(-1040)}}{2\cdot1}= \dfrac{-28\pm\sqrt{4944}}{2}\\\\x\approx21.2\quad or\quad x\approx-49.2[/tex]
x has to be >0 so the answer is 21.2

If 5^a =625, then find the value of a.
Answers
Answer:
a = 4
Step-by-step explanation:
note that 625 = [tex]5^{4}[/tex] , then
[tex]5^{a}[/tex] = [tex]5^{4}[/tex]
Since the bases on both sides are equal, both 5 then equate exponents, so
a = 4
Answer:
4
Step-by-step explanation:
Prime factorize 625
625 = 25 * 25 = 5 * 5 * 5 * 5
[tex]5^{a} = 625\\\\5^{a} = 5^{4}[/tex]
As base are same, compare the exponents
a = 4

The sum of x and 3 times y is 5. The difference of x and y is 5. Write two equations and graph to find the value of y.
Answers
Answer:
for the first one, x + 3 * y = 5
and the second equation, x - y = 5
Step-by-step explanation:
the sum of two numbers means for example the sum of 5 and 8 is 13, so as an equation that is 5 + 8 = 13
the difference is the same thing as the sum but it's subtraction.
and then times is just multiplication.

What is the sum of the interior angles of a rectangle?
4°
360°
180°
90°
Answers
Answer: 180
The sum of the angles in a rectangle is given by (n-2)180 where n is the number of sides of the polygon and n is greater than or equal to 3. For a rectangle, n=4 thus sum of angles is (4–2)180 = 360 degrees. Each interior angle is 360/4 = 90 degrees.
Answer:
180⁰is the interior angle of a rectangle
The price of a desktop computer decreases from $10360 to $1020. Find the percentage decrease its price
Answers
Answer: [tex]915.68\ \%[/tex]
Step-by-step explanation:
Given
Original Price=$10360
New Price=$1020
Percentage decrease in its Price is given by
[tex]\%\ \text{decrease}=\dfrac{\text{New-Original Price}}{\text{Original Price}}\times 100[/tex]
[tex]\Rightarrow \dfrac{10360-1020}{1020}\times 100=915.68\ \%[/tex]

Geometric = uses multiplication
60 - 36 = 24
60 + 24 = 84 (does not give you 100)
Proving this is not Arithmetic

100/60 = 5/3 or 1.66666667
Solution: geometric
Common ratio = 5/3

what is the area of a quadrilateral with vertices at (-6,6), (-1,6),(-6,10), and (-1,10)
Answers
Answer: 20
Step-by-step explanation:
The area of a quadrilateral with given vertices is 20 square units.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have to determine the area of a quadrilateral with vertices at (-6,6), (-1,6),(-6,10), and (-1,10).
As per the attached graph, we can see that the dimensions of the rectangle are as follows:
Length (L) = 5 units
Width (W) = 4 units
Area of the rectangle = L × W
Area of the rectangle = 5 × 4 = 20 square units

Find the number of each type of coin. [Show all
work.]
Answers
Answer:
The answer is 8 quarters, 16 nickles, and 32 dimes
Step-by-step explanation:
First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.) Then we slowly start to solve: 10/4d + 10d + 25/4d = 600 10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d) 75d= 600 x 4 d=600 x 4/75 (same here put everything over 75) d=32 So then n= 2 x 32/4 = 16 Then n would be equal to : 1/4d= 1/4 x 32 = 8 So your answer would be 8 quarters, 16 nickles, and 32 dimes.Hope this helped :)

Step-by-step explanation:
For an n-sided polygon, the length of the apothem is ...
a = r·cos(180°/n)
We assume your problem statement is saying the radius is 10 inches. For a hexagon, n=6 and we have ...
a = (10 in)cos(30°) ≈ 8.66 in
Rounded to the nearest inch, the apothem is 9 in.
