Answer:
The height of the pyramid is 3 m.
Step-by-step explanation:
Given;
volume of pyramid, V = 75 m³
length of the square, L = 5 m
The volume of a pyramid is given as;
V = area of the square base x height
V = Ah
where;
A = L² = 5 x 5 = 25 m²
h = V/A
h = (75) / (25)
h = 3 m
Therefore, the height of the pyramid is 3 m.
Ann and ben had some apples. The ratio of the number of Ann's apples to the ratio of Ben's apple is 2:3. Ann gave 6 apples to ben and now the ratio becomes 1:3. How many apples are all together?
Answer:
There are 12 apples in total.
Step-by-step explanation:
If Anne gave Ben 6 apples then heres how:
2:3 subrtact 6 apples = 1:3
6 apples x 2 = 12 apples =
2 ÷ 2 = 1
Hence, your answer is double 6 which is 12 apples.
Hope this helps :)
What is the common ratio of the geometric sequence below? 18, -6, 2, -2/3
Answer:
Step-by-step explanation:
Common ratios are found by either multiplying the same number in to get to the next number in the sequence, or by dividing out the same number in to go the next number in the sequence. Multiply or divide, NOT add or subtract! Be careful! Obiviously, our numbers are going down, so we are dividing out a specific number as opposed to multiplying one in. To get from 18 to 6, we have to divide by 3; however, the 6 is negative, so we have to divide by -3. To determine if we are correct, divide -6 by -3 and see if that result is the next one in line. -6 divided by -3 is 2. So we are correct, and the common ratio is -3.

Find the distance d. Round your answer to the nearest tenth. Show all your work. Thanksss!
Answer: the distance for d is about 5.8 units
Step-by-step explanation:
Use the pythagorean theorem. a^2 + b^2+= c^2 . in this case, c^2 is the distance for d.
5^2 + 3^2= d^2
25+9= d^2
34= d^2
square both sides and d is approximately 5.818

stay safe healthy and happy.y is directly proportional to the square root of x
if y = 60 when x = 36
find x when y = 80
Answer:
x = 64
Step-by-step explanation:
Given y is directly proportional to [tex]\sqrt{x}[/tex] then the equation relating them is
y = k[tex]\sqrt{x}[/tex] ← k is the constant of proportion
To find k use the condition y = 60 when x = 36, then
60 = k [tex]\sqrt{36}[/tex] = 6k ( divide both sides by 6 )
10 = k
y = 10[tex]\sqrt{x}[/tex] ← equation of proportion
When y = 80 , then
80 = 10[tex]\sqrt{x}[/tex] ( divide both sides by 10 )
8 = [tex]\sqrt{x}[/tex] ( square both sides )
64 = x

The circumference of the circle is 75.36cm
Step-by-step explanation:
There are two ways you can solve this, one is by using the radius and multiplying it by 2 and then pi which is 3.14, and the other is to use the diameter which is the radius times 2, and the thingy gave you the diameter, and you multiply it by 3.14 which is pi

Answer:
a square 175 m on a side
Step-by-step explanation:
Let x and y represent the sides of the rectangle. Then the perimeter is ...
P = 2(x + y) = 700
x + y = 350 . . . . . . . divide by 2
y = 350 -x . . . . . . . . subtract x
The area of the fenced field is ...
A = xy
A = x(350 -x)
This is a quadratic function that has zeros at x = 0 and x = 350. The axis of symmetry is x = (0 +350)/2 = 175. The vertex (maximum area) is on the axis of symmetry, so corresponds to x = 175. The y-value there is ...
y = 350 -x = 350 -175 = 175
That is, the maximum area will be obtained when the fenced area is a square. Each side of the square is 175 m, which is 1/4 of the total length of the fence.
The dimensions of the space are 175 m by 175 m.

J
$225,000.00
Answer:
$2,250
Step-by-step explanation:
5% of 15,000 is 750. If we multiply 750 by the number of terms, 3, we get an answer of $2,250.
Answer:
$2,250
Step-by-step explanation:
Use the simple interest formula i = prt. Here the principal, p, is $15,000 and the interest rate, r, is 0.05. Then:
i = ($15,000)(0.05)(3) = $2,250

Solve for x:
Answer:
Angle between two tangents or two secants is the half of the difference of intercepted arcs.
#1
x = 1/2(250° - (360° - 250°)) = 1/2(250° - 110°) = 1/2(140°) = 70°#2
50° = 1/2(170° - x)100° = 170° - xx = 170° - 100°x = 70°5. A ladder leans against a building. The top of the ladder touches the building 10 feet above the ground. The foot of the
ladder is 4 feet from the building. Find, to the nearest degree, the angle that the ladder makes with the level ground.
(3 points)
Answer:
68 degrees
Step-by-step explanation:
The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.
The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft. Thus,
tan x = (opp side) / (adj side) = 10/4. Using the inverse tangent function, we find that the angle in question is
arctan (10/4) = 68 degrees

A student has taken three math tests so far this semester. His scores for the first three tests were 71, 75, and 79. Part A: Suppose his test scores continue to improve at the same rate. What will be the grade on the sixth and (final) test?
Answer:
The grade of this sixth and (final) test would be 91.
Step-by-step explanation:
This is an arithmetic series since each time the data is increasing by the common difference of 4, and we already know a₁ which is the first term in the sequence is 71, therefore we can say:
a₁ = 71
r = 4
a₆ = the sixth term that needs to be found out
n = 6
Formula of an arithemetic series:
aₙ = a₁ + r(n - 1)
a₆ = 71 + 4(6 - 1)
a₆ = 71 + 4(5)
a₆ = 71 + 20
a₆ = 91
Hence, the grade of this sixth and (final) test would be 91.
Hope this helps!

The total cost of 8 identical pens and 2 identical files is $32 The total cost of 3 such files is the same as the total cost of 4 such pens. Find the cost of each file
Answer:
$4
Step-by-step explanation:
Given that
total cost of 8 identical pens and 2 identical files is $32
And, the The total cost of 3 such files would be the same as the total cost of 4 such pens
We need to find out the cost of each file
So let us assume the following things
Pens be x
File be y
Now
8x + 2y = $32 ....(1)
3y = 4x.........(2)
y = 4x÷ 3
Now put the value of y in equation 1
8x + 1.33x = 32
x = $3.55
x = $4
The cost of each file based on the given information is $4
where:
Let the cost of a pen be xLet the cost of a file be ySimultaneous equationIf the total cost of 8 identical pens and 2 identical files is $32, hence;
8x + 2y = 32
If the total cost of 3 such files is the same as the total cost of 4 such pens, then;
4x = 3y
From the equation
8x + 2y = 32
2(4x) + 2y = 32
2(3y) + 2y = 32
8y = 32
y = 4
Since 6=4x = 3y
4x = 3(4)
4x = 12
x= 3
Hence the cost of each file is $4

Answer:
The measure of angle 7 is twice the measure of angle 2, then the measure of angle 7 is
angles 2 and 7 equal 180 degrees. 180 = 2x + x
180 = 3x
x = 60
angle 7 is twice x
angle 7 = 120
