Volume of the following triangular prism is 960 cm3…
a) Determine the length of the base of the triangle.
b) Determine the area of the triangle.
help plz
Answer:
Step-by-step explanation:
a). By applying Pythagoras theorem in right triangle ABC,
AC² = AB² + BC²
20² = 16² + BC²
BC = [tex]\sqrt{400-256}[/tex]
= 12
Therefore, another leg of the triangular base = 12 cm
Area of the triangular base ABC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(16)(12)[/tex]
= 96 cm²
Volume of a triangular prism = Area of the triangular base × height
960 = 96 × b
b = 10 cm
b). Area of the triangle ABC = 96 cm²
write the equation of the line for the following table of values.
x. -3 -5 -7 -9 -11
y. -16 -26 -36 -46 -56
Plz helppp 35 points:)
Answer:
We conclude that the equation of the line is:
[tex]y = 5x + 1[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the data table
x -3 -5 -7 -9 -11
y -16 -26 -36 -46 -56
From the table taking two points
(-3, -16)(-5, -26)Determining the slope between (-3, -16) and (-5, -26)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-3,\:-16\right),\:\left(x_2,\:y_2\right)=\left(-5,\:-26\right)[/tex]
[tex]m=\frac{-26-\left(-16\right)}{-5-\left(-3\right)}[/tex]
[tex]m=5[/tex]
Thus, the slope of the line is: m = 5
substituting m = 5 and (-3, -16) in the slope-intercept form of the line equation to determine the y-intercept b
[tex]y = mx+b[/tex]
-16 = 5(-3) + b
-16 = -15 + b
b = -16+15
b = 1
Thus, the y-intercept b = 1
now substituting m = 5 and b = 1 in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]y = 5x + 1[/tex]
Therefore, we conclude that the equation of the line is:

Answer:
$10511.075
Step-by-step explanation:
Given :
Interest rate, r =. 1.25% = 0.0125 compounded semianually
Principal = 10000
Number of years, t = 4 years
Compound interest :
A = P(1 + r/n)^nt
A = final amount ; n = number of compounding times per period
n = 2 (quarterly)
A = 10000(1 + 0.0125/2)^2*4
A = 10000(1 + 0.00625)^8
A = 10000(1.00625)^8
A = 10000 * 1.051107529
A = 10511.075
Final. Amount to. Be repaid = $8515.13
is 4 yards greater than or less than 10 feet

Step-by-step explanation:
A thief who is particularly knowledgeable about statistics and the legal system determines that if he commits a given heist the probability that he is never caught is 60%. If he is arrested he will go to trial where there is a 30% chance the jury will acquit him, a 30% chance he is convicted and serves a prison sentence less than five years, and a 40% chance the sentence is more than five years.
What is the probability that the thief is not imprisoned in 5 years?
What is the probability that the thief was arrested given that he is not imprisoned in 5 years?
9514 1404 393
Answer:
about 28.6%
Step-by-step explanation:
The conditional probability equation can be used:
P(arrested | not in jail) = P(arrested & not in jail)/P(not in jail)
= 0.24/0.84 = 2/7 ≈ 28.6%

Answer:
A. 442.05
Step-by-step explanation:
✔️First find the radius of circle J:
θ = 43°
Acr length = 52.8
Thus,
Acr length = θ/360*2πr
Plug in the values
52.8 = 43/360*2*π*r
52.8 = 0.751r
Divide both sides by 0.75
52.8/0.75 = r
r = 70.4 (nearest hundredth)
✔️Find the Circumference of circle J:
Circumference = 2πr
Radius (r) of circle J = 70.4
Plug in the values
Circumference = 2*π*70.4
= 442.34
This is close to the answer in option A. Therefore, the answer is 442.05.

Which of the following are magnitudes for rotational symmetry of the ellipse below about its center?
Choose all answer that apply:
All magnitudes less than 360°
180°
270°
Answer:
180 bestie
Step-by-step explanation:
The magnitude of rotational symmetry of the given ellipse is angle 180°.
What is the equation of ellipse if its major and minor axis and center are given?Suppose that the major axis is of the length 2a units, and that minor axis is of 2b units, and let the ellipse is centered on (h,k) with major ellipse parallel to x-axis,
then the equation of that ellipse would be:
[tex]\dfrac{(x-h)^2}{a^2} + \dfrac{(y-k)^2}{b^2} =1[/tex]
Coordinates of its foci would be: [tex](h \pm c, k)[/tex] where c^2 = a^2 - b^2
Let the magnitude of rotational symmetry of the given ellipse is angle θ.
Measure of angle θ is a straight line.
Measure of angle θ = 180°
Therefore, with a rotation of 180° ellipse will overlap itself.

Answer:
Mary has two friends over, she wants to split half of a cake she has left over into thirds for her and her friends. 1/2 ÷ 3 is 1/6. This means that each friend will get 1/6 of the full cake.
Step-by-step explanation:
I make up stories and know how to divide fractions. To solve a division problem like this you want to take the 3 and turn it into 3/1. then, flip the 1/2 around to it is 2/1. Then, multiply the two together.
Please find x....................
Answer:
x = 14.1
Step-by-step explanation:
Reference angle = 62°
Side opposite to reference angle = x
Hypotenuse = 16
Applying trigonometric ratio, thus:
Sin 62 = x/16
Multiply both sides by 16
16*sin 62 = x
14.1271615 = x
x = 14.1 (nearest tenth)
