Matching angles of two congruent figures are called corresponding angles. The angles that are in the same position will have the same measurement.
A right pyramid with a square base is shown. the length of the base is 8 inches and the slant height is 5 inches. kabir wants to know the volume of a solid right pyramid with a square base. he uses a ruler to measure the length of the base as 8 inches. he then measures the slant height to be 5 inches. the hypotenuse of the right triangle used to determine the height is inches. the leg of the right triangle that lies on the same plane as the base is inches. the height of the pyramid is inches. the volume of the solid pyramid is cubic inches.
The volume of the given pyramid comes to be 64 cubic inches.
Length of the square base a= 8 inches
Slant height l =5 inches
What is the volume of a pyramid?The volume of a pyramid is with base area A and height h is 1/3Ah.
So, base area A= 8*8 =64 square inches.
From Pythagoras theorem
[tex]l^{2} =(\frac{a}{2})^2 +h^{2}[/tex]
[tex]5^{2} =(\frac{8}{2})^2+h^{2}[/tex]
[tex]h=3[/tex] inches
So, volume of the pyramid = 1/3*A*h
=1/3*64*3
=64 cubic inches.
Hence, the volume of the given pyramid comes to be 64 cubic inches.

Answer:
x = 2
Step-by-step explanation:
Given :
3x = 5x - 4Add 4 on each side
3x + 4 = 5x - 4 + 43x + 4 = 5xSubtract 3x from each side
3x - 3x + 4 = 5x - 3x4 = 2xDivide 2 from each side

Ms. Washington also borrowed money for a computer. The equation D=-100m + 1,800 represents the amount Ms. Washington owes, D. in
dollars, after m months.
Which person will owe more money after 9 months? Move the correct words and dollar amount to the blanks to complete the sentence.
After 9 months.
will owe
more than
Mr. Silberman
Ms. Washington
$50
$100
$150
$200
$250
$300
Answer: Mr. Silberman has to pay $150 more than Ms. Washington.
Step-by-step explanation: First calculate how much tax Mr. Silberman will have to pay off after 9 months. 50x9=450, so $450 is how much tax he will have to pay. Add that to 1,500, which is the total cost of the computer, which equals $1,950.
Ms. Washington only has to pay $1,800. Mr. Silberman has to pay $1,950. So Mr. Silberman has to pay more. He has to pay $150 more than Ms. Washington.

Find a fourth degree polynomial equation with rational coefficients that has roots -1 multiplicity of 2 and 1-4i.
A. x^4-18x^2-32x-15
B. x^4+14x^2+32x+17
C. x^4+2x^3+6x^2+32x+40
D. x^4+4x^3+2x^2+12x+45
A polynomial of degree 4 will have 4 zeros. The zero of 3 with a multiplicity of 2 counts as two of these zeros. You've also been given a zero of -i. So it seems that we only have 3 of the 4 zeros. We need all 4 to be able to form the desired polynomial.
You didn't mention that the polynomial should have real coefficients. But I'm going to assume it because otherwise we can't solve the problem. If a polynomial with real coefficients has a complex zero, then the complex conjugate of that complex zero will also be a zero. This is how we will find the 4th zero.
A complex number in standard form is a + bi. Its complex conjugate is a + (-bi) or a - bi. The complex zero we were given is -i. In standard form this would be 0 + (-i). The complex conjugate of 0 + (-i) would be 0 - (-i) or 0 + i or just i.
So the four zeros of the desired polynomial are 3 (twice), -i and i. If a number "z" is a zero of a polynomial then (x - z) is a factor of that polynomial. Using this fact and the four zeros we can write a factored form of our desired polynomial:
f%28x%29+=+a%28x-3%29%28x-3%29%28x-%28-i%29%29%28x-i%29
Simplifying the 3rd factor we get:
f%28x%29+=+a%28x-3%29%28x-3%29%28x%2Bi%29%28x-i%29
where the "a" is any non-zero number. Since there are an infinite number of non-zero numbers, there will be an infinite number of possible correct solutions to this problem. To make things easy we will choose to make "a" be 1. This makes our factored polynomial:
f%28x%29+=+%28x-3%29%28x-3%29%28x%2Bi%29%28x-i%29
All we have to do now is multiply this out. We can simplify this process if we take advantage of some factoring patterns. The first two factors can be multiplied using:
%28a-b%29%5E2+=+a%5E2-2ab%2Bb%5E2
And the last two factors can be multiplied using:
%28a%2Bb%29%28a-b%29+=+a%5E2-b%5E2
With these patterns we get:
f%28x%29+=+%28%28x%29%5E2-2%28x%29%283%29%2B%283%29%5E2%29%28%28x%29%5E2-%28i%29%5E2%29
Simplifying inside each factor we get:
f%28x%29+=+%28x%5E2-6x%2B9%29%28x%5E2-i%5E2%29
And since i%5E2+=+-1 this becomes:
f%28x%29+=+%28x%5E2-6x%2B9%29%28x%5E2-%28-1%29%29
or
f%28x%29+=+%28x%5E2-6x%2B9%29%28x%5E2%2B1%29
We have one more multiplication. There are no shortcuts for this one. We have to multiply each term of one factor times each term of the other and then add like terms, if any:
f%28x%29+=+x%5E2%2Ax%5E2%2Bx%5E2%2A1%2B%28-6x%29%2Ax%5E2%2B%28-6x%29%2A1%2B9%2Ax%5E2%2B9%2A1
Simplifying...
f%28x%29+=+x%5E4%2Bx%5E2%2B%28-6x%5E3%29%2B%28-6x%29%2B9x%5E2%2B9
f%28x%29+=+x%5E4%2B10x%5E2%2B%28-6x%5E3%29%2B%28-6x%29%2B9
Re-ordering into standard form:
f%28x%29+=+x%5E4%2B%28-6x%5E3%29%2B10x%5E2%2B%28-6x%29%2B9
This is a polynomial function of degree 4 with the given zeros.
P.S. As mentioned earlier, this is not the only possible correct answer. This is the answer when you make "a" equal to 1. Other values for "a" give us different polynomial functions which also have the same zeros. For example, if we had chosen a = 2 we would have gotten f%28x%29+=+2x%5E4%2B%28-12x%5E3%29%2B20x%5E2%2B%28-12x%29%2B18.

Jake and maddie each take the closest path from their homes to the store. based on the picture below, what is the approximate difference in the distance each person traveled to the store?
Answer:
we can't really answer the question without the pictue, but if the time count stays the say and the distance doen't, it would be (t=time/d=distance) (lets say time was an hour and you traveled 11 miles each hour,) then it would be 11t = d

26² = (13 + x) * 13
[tex]\sf (13 +x)*13 = 26 *26\\[/tex]
[tex]\sf 13 + x =\dfrac{26*26}{13}[/tex]

Which of the following parallelograms is NOT similar to the others?
A
B
C
D
the answer is D
Step-by-step explanation:
Answer: C
Step-by-step explanation:
The height of the parallelogram for A is 3 units while the length the base is 6 units.
For D it follows this same pattern, the height is 1 which is half of the length of the base, 2.
B also follows this pattern, the height is 2 which is half of the length of the base, 4
C does not follow this pattern and is the odd one out.
The time t required to empty a water tank varies inversely as the rate of pumping p. A pump can empty a water tank in 40 min at the rate of 120 gal/min. Write the equation of the inverse variation. How long it will take the pump to empty the water tank at the rate of 200 gal/min?
the question requires:
the time t required.
the equation of the inverse variation.
how do find t:
first we determine how much the tank holds by multiplying 120 by 40.
the tank holds 4800 gallons.
so now to find t we can use the formula v = d/t where d is the 4800 gallons.
so: t = d/v
t = 24 minutes
now for the equation of the inverse variation.
we can say that the equation is t = d/v since t and v are inversely proportional.
note that v and t stand for velocity and time respectively.
make sure to ask if you need any further guidance!!
Answer:
t = 24

If 1/3 gallon of paint covers 1/6 of a wall, then how many quarts of paint are needed for the entire wall?
Answer:
8 quarts
Step-by-step explanation:
1/3 of a gallon ---1/6 of a wall
x - 1 (all the wall)
x = (1 x 1/3) / 1/6
x = 1/3 / 1/6
x = 6/3
x = 2 gallons
1 gallons - 4 quarts
2 gallons - x
x = (2 x 4) / 1
x = 8 / 1
x = 8 quarts
Compound Shapes (with circles)
Find the area
Answer:
18.8
Step-by-step explanation:
First find the area of the rectangle, which is 4x3 (base x height) the area of the rectangle is 12.
We are given the radius as 2 for the quarter circles, and 2 quarter circles form 1 semicircle, so really we can solve for the area of one semi circle using the formula ( (pi*radius²)/2 ). Plug in the values and you should get 6.28.
Next, you add the area of the figures so 12+6.8 which is equal to 18.8.
