volume of a pyramid with a square base of length 5m is 75m³. Find it's hieght
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.
If f(x)= x2 + 5, and g(x) = 3x - 11, find (g(f(-3)).
Answer:
31
Step-by-step explanation:
first find f(-3)
f(-3) = (-3)^2 +5
= 9+5 = 14
The find g(f(-3) = g(14)
= 3*14-11
= 42-11
=31

which expression represents the difference of (5x-3y) and (8x+8y)?
Given:
The expressions are:
[tex](5x-3y)[/tex] and [tex](8x+8y)[/tex]
To find:
The difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex].
Solution:
Difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex] is written as:
[tex]Difference=(5x-3y)-(8x+8y)[/tex]
On simplification, we get
[tex]Difference=5x-3y-8x-8y[/tex]
[tex]Difference=(5x-8x)+(-3y-8y)[/tex]
[tex]Difference=-3x-11y[/tex]
Therefore, the difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex] is [tex]-3x-11y[/tex].

the sum of two numbers is 65 and their difference is 7. What is the greater of the two numbers?
Answer:
The numbers are 35 and 28
35+28=65
35-28=7
Step-by-step explanation:
Brainliest?..
Answer:
X+y =65 x-y=7 y=65-x (plug in 65-x) for y. X-(65-x)=7 so x-65+x=7
2x=72 so x =36 65-36=29 The bigger number is 36.

Write the point-slope form of an equation of the line through the points (-7, 7) and (4, 1).
A. y−4=−611(x−1)
B. y+1=−611(x+4)
C. y+7=−611(x−7)
D. y−7=−611(x+7)
Answer:
D) y-7=-6/11(x+7)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-7)/(4-(-7))
m=-6/(4+7)
m=-6/11
y-y1=m(x-x1)
y-7=-6/11(x-(-7))
y-7=-6/11(x+7)
y=-6/11x-42/11+7
y=-6/11x-42/11+77/11
y=-6/11x+35/11
Find the value of x
please helppp
2 • xy (midsegment) = sum of the bases
Plug in the numbers
2 • 12.5 = 3x + 1 + 15
Add 1 and 15 together
25 = 3x + 16
Subtract 16 on both sides and you should get:
9 = 3x
Divide both sides by 3
9/3 = 3x/3
Answer:
3 = x
this is exact and approximate pi

Find the value of x. The diagram is not to scale.
Answer:
[tex]x=14[/tex]
Step-by-step explanation:
Since lines [tex]\overrightarrow{f}[/tex] and [tex]\overrightarrow{g}[/tex] are parallel, the angles labelled in the diagram must be supplementary (add up to [tex]180^{\circ}[/tex]). Therefore, we have the following equation:
[tex]4x+(7x+26)=180,\\11x+26=180,\\11x=154,\\x=\boxed{14}[/tex]

Answer:
14 + 5[tex]\sqrt{3}[/tex]
a = 14, b = 5, c = 3
Step-by-step explanation:
Multiply the brackets out:
[tex](2\sqrt{3} )(3\sqrt{3} ) = (2)(3)(\sqrt{3})(\sqrt{3}) = (6)(3) = 18[/tex]
[tex](2\sqrt{3} -1)(4+3\sqrt{3} ) = 8\sqrt{3} +18 - 4 - 3\sqrt{3}[/tex]
[tex]= 14 + 5\sqrt{3}[/tex]

Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?
Answer:
10 feet
Step-by-step explanation:
Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?
The rug is shaped as a rectangle
The formula for the Perimeter of a rectangle = 2L + 2W
Perimeter = 36 feet
Length = 8 feet
Hence
36 = 2(8) + 2W
36 = 16 + 2W
2W = 36 - 16
2W = 20
W = 20/2
W = 10 feet
Therefore, the Width of the rug is 10 feet

Answer:
60°
Step-by-step explanation:
just in case if line AC and BD are straight lines,
angle EGD will be 180-90-30=60
and EGD will equal to x°becoz they are just in opposite
Answer:
The Answer is 60
Step-by-step explanation:
If you look at E B and F those make up a 180-degree angle if you look across from B then you will see that it is a 90-degree angle so you can assume that B is also a 90-Degree angle so if you add up 30 + 90 = 120
You then can subtract 180 - 120 to get the answer 60
So therefor the answer is 60

Write three different expressions in any form equivalent to each given expressions below.
Answer:
3^-3 for the first answer. The second answer is 3^7.
Step-by-step explanation:
If you multiply two numbers with the same base and exponents, the exponents are added up.
If you divide two numbers with the same base and exponents, the numerator would subtract the denominator.
So the answer to the first question is 3^-3. The second answer would be 3^7.

d = 16.76 inches
Step-by-step explanation:
We can extend the definition of the Pythagorean theorem to 3-dimensions:
[tex]d = \sqrt{ {x}^{2} + {y}^{2} + {z}^{2} } [/tex]
Let x = 10 in
y = 10 in
z = 9 in
[tex]d = \sqrt{ {(10)}^{2} + {(10)}^{2} + {(9)}^{2} } [/tex]
[tex]d = \sqrt{281} = 16.76 \: in[/tex]
