3. Simplify 3 x g x 5 x h
Answer:
3 into g into 5 into h
in this we will group the term 3 and 5 together and then the g and h
so the answer will be 3 into 5 into g into h = 15gh
The expression 3 × g × 5 × h is in the simplified form of 15gh.

A triangular pyramid has a right triangle for its base. The perpendicular sides of the triangle are 10 inches and 18 inches long. Compute the volume of the triangular pyramid if the height is 14 inches.
A. 252 in 3
B. 420 in 3
C. 2520 in 3
D. 1260 in 3
Answer:
90 cubic inches
Step-by-step explanation:
The formula for a triangular pyramid is 1/3AH. A is the area of the base. H is the height of the pyramid. So to find the area of a right triangle, you would use the formula (a x b)/2. So (10 x18)/2 is 90 inches^2. Now you can fill in the first formula. 1/3(90 x 14), which equals 420 inches^3.
V = 1/3 · area of base · height
V = 1/3 · 18 · 15
V = 6 · 15
V = 90

The ∠DCO will be 2·x, 69° is the sum of ∠DCO and x° is x = 23°
What is a circle?A curving line makes up the form of a circle. It is spherical, and every point along the curving line is equally spaced first from the center. Due to its multiple nature, this form is flat.
Points on the circle is A, B, C, and D
Straight lines present are AOBE and DCE
Segment CO = Segment CE
∠AOD = 69°
∠CEO = x°
∠OCD = ∠ODC as this is an isosceles triangle
an exterior angle of a triangle can be determined as
69° = ∠x° + ∠ODC
Because of the Angle sum property of a triangle
∠DOC = 180 - 2×∠ODC
Angles added together on a linear fashion are supplementary.
180 - 2×∠ODC + x° + 69° = 180°
x° + 69° - 2×∠ODC = 0
A triangle's exterior angle is equal to the product of its diagonal internal angles
∠ODC = 2·x°
69° = x° + ∠ODC = x° + 2·x° = 3·x°
69° = 3·x°
x = 69° ÷ 3
x = 23°

.A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport. The total
charge is AED 135
How far, in kilometers, is the trip to the airport?
Given:
A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport.
The total charge is AED 135.
To find:
How far, in kilometers, is the trip to the airport?
Solution:
Let x km be the trip to the airport.
A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport. So, total changes for x km trip is
[tex]T=10+250x[/tex]
The total charge is AED 135.
[tex]10+250x=135[/tex]
[tex]250x=135-10[/tex]
[tex]250x=125[/tex]
Divide both sides by 250.
[tex]x=\dfrac{125}{250}[/tex]
[tex]x=\dfrac{1}{2}[/tex]
[tex]x=0.5[/tex]
Therefore, the trip to the airport is 0.5 km.

Find the sum of the interior angles, then solve for x.
Help!!
Answer:
91 + 125 + 92 +(3x-5) + (4x- 8)= 540
308 +3x -5 +4x -8 =540
7x - 295 = 540
7x = 540 -295
7x = 245
x = 245/7
x = 35
Step-by-step explanation:
Answer:
x=35²
Step-by-step explanation:
1. Since all pentagons have a total interior angle sum of 540, add all the terms together and set them equal to 540:
[tex]91+92+125+\left(4x-8\right)+\left(3x-5\right)=540[/tex]
2. combine like terms. (91, 92, -8, -5 and 125) (3x and 4x)
[tex]295+7x=540[/tex]
3. subtract 295 from 540:
[tex]7x=540-295\\7x=245[/tex]
4. Divide 245 by 7.
[tex]\frac{7x}{7}=\frac{245}{7}\\\\x=35[/tex]

help plssss
Answer:
Please check the explanation.
Step-by-step explanation:
Part 1)
5x + 9y, when x=8, y=11
substituting x=8, y=11 in 5x + 9
5x + 9y = 5(8) + 9(11)
= 40 + 99
= 139
Part 2)
a³ –c + b, when a=3, b=6, c=8
substituting a=3, b=6, c=8 in a³ –c + b
a³ –c + b = (3)³ - 8 + 6
= 27 - 2
= 25
Part 3)
4(g –h) +10, when g=12, h=7
substituting g=12, h=7 in 4(g –h) +10
4(g –h) +10 = 4(12 - 7) + 10
= 4(5) + 10
= 20 + 10
= 30
Part 4)
k³ –4j +12, when k=8, j=2
substituting k=8, j=2 in k³ –4j +12
k³ –4j +12 = (8)³ - 4(2) + 12
= 512 - 8 + 12
= 516

Suppose you asked 100 commuters how much they spend each year and obtained a mean of $167 spent on transportation and a standard deviation of $40. Using the 2 SE rule of thumb, calculate a 95% confidence interval for the mean and select the values that come closest to those that would fill the spaces in the following interpretation: we can be 95% confident that the mean amount of money spent on transportation lies between _____ and _____ .
Answer:
The correct answer is "$159 and $175".
Step-by-step explanation:
The give values are:
Mean,
= $167
Standard deviation,
[tex]\sigma[/tex] = $40
Number of commuters,
n = 100
Now,
⇒ [tex]SE=\frac{\sigma}{\sqrt{n} }[/tex]
On putting the given values, we get
⇒ [tex]=\frac{40}{\sqrt{100} }[/tex]
⇒ [tex]=\frac{40}{10}[/tex]
⇒ [tex]=4[/tex]
By using the 2 SE rule of thumb, we get
= [tex]$(167 - 2\times 4)[/tex]
= [tex]167-8[/tex]
= [tex]159[/tex] ($)
Or,
= [tex](167 + 2\times 4)[/tex]
= [tex]167+8[/tex]
= [tex]175[/tex] ($)
i.e,
$159 and $175
Solve X³=64. im trying to finsh my class
Answer:
C
Step-by-step explanation:
multiply the number 3 times
A 1536
B 512
C 64!!!D Dum answer choice
Answer:
x = 4
Step-by-step explanation:
We have the equation x^3 = 64 and are asked to solve for x.
To solve, we need to isolate x.
x^3 = 64
Cube root both sides by 3 to get x alone :
[tex](x^3)^3 = \sqrt[3]{64}[/tex]
[tex]x = \sqrt[3]{64}[/tex]
Solve for the cube root of 64 :
[tex]\sqrt[3]{64} = 4[/tex]
[tex]x = 4[/tex]

Answer:
110 degrees
Step-by-step explanation:
Because these angles are vertical, 5x+15=8x-42. thus, 15=3x-42, 3x=57, and x=19. 5x+15=5(19) +15=110. So, m<CDE=110 degrees.
Answer:
110°
Step-by-step explanation:
Since CDE and FDG are vertical, they are congruent, so:
5x + 15 = 8x - 42
Solve the equation for x
57 = 3x
19 = x
Then solve for one of the angles (I chose CDE but FDG would also work)
5(19)+15
95 + 15
110
