Answer:
16 millimeters
Step-by-step explanation:
Length of the Triangular Prism=4 millimetersBase Length of One Triangular Face=13 millimeters.Volume of the Prism =416 cubic millimeters.Now:
Volume of a Prism=Base Area X Prism Length
Since we have a triangular base:
Volume of the Prism=(0.5 X Base X Height) X Prism Length
Substituting the given values, we obtain:
416=(0.5 X 13 X Height) X 4
416=26 X Height
Divide both sides by 26
Height of its triangular face=16 millimeters
Answer:
h = 16 mm
Step-by-step explanation:
Th volume of the prism is:
[tex] V = A*l [/tex] (1)
Where:
V. is the volume of the triangular prism = 416 mm³
A. is the area of the prism = ?
l: is the large of the prism = 4 mm
The area of the triangular face of the prism is:
[tex] A = \frac{1}{2}bh [/tex] (2)
Where:
b: is the base of the triangular face = 13 mm
h: is the height of the triangular face = ?
From equation (1) we have:
[tex] V = A*l [/tex]
[tex] A = \frac{V}{l} = \frac{416 mm^{3}}{4 mm} = 104 mm^{2} [/tex]
Now, using equation (2) we can find the height of the triangular face:
[tex] A = \frac{1}{2}bh [/tex]
[tex] h = \frac{2A}{b} = \frac{2*104 mm^{2}}{13 mm} = 16 mm [/tex]
Therefore, the height of the triangular face is 16 mm.
I hope it helps you!
Which of the binomials below is a factor of this
trinomial?
x2 - 13x + 30
O A. X-3
O B. X+5
O c. x-5
O D. X+ 3
Answer:
A
Step-by-step explanation:
Given
x² - 13x + 30
Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 13)
The factors are - 3 and - 10, since
- 3 × - 10 = + 30 and - 3 - 10 = - 13 , thus
x² - 13x + 30 = (x - 3)(x - 10) ← in factored form
Thus (x - 3) is a factor of the polynomial → A
Answer:
[tex](x - 3)[/tex]
Answer A is correct
Step-by-step explanation:
[tex]{x}^{2} - 13x + 30 \\ {x}^{2} - 10x - 3x + 30 \\ x(x - 10) - 3(x - 10) \\ = (x - 3)(x - 10)

It costs $10 to make earphones, and the start-up costs for manufacturing are $5,000. How many earphones must be produced to get to a cost per unit of $20 a. 100 b. 30 c. 200 d. 500
With that information we can create the equation
10x + 5000 = 20x
where x is the number of earphones produced
10x is the cost to make each earphone, 5000 being the fixed costs of manufacturing, and 20x being the total revenue of selling each earphone for $20
Now to solve the equation:
subtract both sides by 10x
10x - 10x + 5000 = 20x - 10x
5000 = 10x
Now divide both sides by 10
5000/10 = 10/10 x
500 = x
Answer: D
Hope it helps :)

A cake has circumference of 25 1/7inches. what is the area of the cake? use 227 to approximate π. round to the nearest hundredth. enter your answer in the box.
Answer:
Step-by-step explanation:
Hello,
The circumference of the cake is 25(1/7), but we don't know the area of the cake.
Assuming the cake has a shape of a circle,
Circumference of a circle = 2πr
Where r = radius of the circle.
Area of a circle = πr²
But π = 22 / 7
We have to first find the value of r.
2πr = 25(1/7)
2×(22/7)×r = 25(1/7)
(44/7)r = 176 / 7
(44 × 7)r = 176 × 7
44r = 176
r = 176 / 44
r = 4 inches
Area of the circle = πr²
A = (22 / 7) × 4²
A = 22 / 7 × 16
A = 352 / 16
A = 22 (inches)²
The area of the cake is 22in²

it is not a triangle because a+b is not = c
Answer: These given lengths do not make up a right triangle.
Step-by-step explanation:
In order to figure out if this is a right triangle or not, we would need to use the Pythagorean Theorem in order to verify if these lengths satisfy the properties of a right triangle. We would need to use the formula a^2 + b^2 = c^2.
14^2 + 15.5^2 = 20.8^2
196 + 240.25 = 432.64
436.25 ≠ 432.64
Therefore, this is not a right triangle.

HELP! ASAP: The graph relates the number of gallons of white paint to the number of gallons of red paint Jess used to make the perfect pink. Write an equation that describes the relationship.
Answer:
y = (2/3)*a
Step-by-step explanation:
We can write the equation using the linear equation model:
y = ax + b
Then, to find the values of 'a' (slope) and 'b' (y-intercept), we can use two points of the graph.
Using the point (0,0), we have:
0 = a*0 + b
b = 0
Using the point (3,2), we have:
2 = a*3 + b
a = 2/3
So our equation is:
y = (2/3)*a

The ratio of lions to tigers at the Metropolitan Zoo is 12 to 8. Which ratio is equivalent to 12 to 8? A.6 to 3 b.8 to 12 c.15 to 10 d.24 to 18
Answer:
c.15 to 10
Step-by-step explanation:
The ration 12 to 8 means that for every 12 lions there are 8 tigers in the zoo.
Ratios have the quality of conservate their meaning when both values in the ratio are multiplied or divided by the same number.
For example:
a ratio of 2 to 4 is the same as a ratio of 3 to 6 (both values are multiplied by 1.5 (or in fraction by 3/2) ).
in the same way that the ratio 9 to 3 is the same as 3 to 1 (divide both values by 3).
In this case we are looking for an equivalent ratio to the 12 to 8 ratio, the answer is
c.15 to 10
because this results from multiplying the two original values by 1.25 or, in fraction, by 5/4. You can see this becase
12*1.25 = 15
and
8*1.25 = 10
we get that when we multiply the ratio 12 to 8 by 1.5 the equivalent ratio is option C.

2 people are trying different phones to see which one has the better talk time. ChatLong has an average of 18 hours with a standard deviation of 2 hours and Talk-a-Lot has an average of 20 hours with a standard deviation of 3. The two people who tested their phones both got 20 hours of use on their phones. For the z-scores I got 1 for the ChatLong company and 0 for Talk-a-lot. What is the percentile for each z-score?
Answer:
Step-by-step explanation:
The percentile for the z scores are gotten from the normal distribution table. The z cores are already known.
1) For the ChatLong company, the z score is 0. The area corresponding to the z score from the normal distribution table is 0.5. Therefore, the percentile is
0.5 × 100 = 50%
2) For the Talk-a-lot company, the z score is 1. The area corresponding to the z score from the normal distribution table is 0.84. Therefore, the percentile is
0.84 × 100 = 84%
The whole is 1,000,000. 50,000 is what percent of that
Answer:
500000000
Step-by-step explanation:
50,000 percent is or 1,000,000 is 500000000. I hope this is correct. I did the answer by multiplying them together.

which points are separated by distance of 6 units?
A. (5,6) (4,6)
B. (1,3) (6,3)
C. (8,1) (1,1)
D. (7,2) (1,2)
Option (D) points (7,2) (1,2) are separated by distance of 6 units.
What is distance between two points?It is the length of the straight line connecting these points in the coordinate plane. This distance can never be negative, therefore we take the absolute value while finding the distance between two given points. The distance formula is an application of the Pythagorean theorem.
For the given situation,
The distance between the two points must be 6 units.
Let the points be (x1,y1) and (x2,y2)
The distance formula is
[tex]d=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2} }[/tex]
We need to check all the options.
Option A: (x1,y1) = (5,6), (x2,y2) = (4,6)
⇒ [tex]d=\sqrt{(4-5)^{2} +(6-6)^{2} }[/tex]
⇒ [tex]d=\sqrt{(-1)^{2} +(0)^{2} }[/tex]
⇒ [tex]d=\sqrt{1}[/tex]
⇒ [tex]d=1[/tex]
Distance ≠ 6. So option A is incorrect.
Option B: (x1,y1) = (1,3), (x2,y2) = (6,3)
⇒ [tex]d=\sqrt{(6-1)^{2} +(3-3)^{2} }[/tex]
⇒ [tex]d=\sqrt{(5)^{2} +(0)^{2} }[/tex]
⇒ [tex]d=\sqrt{25}[/tex]
⇒ [tex]d=5[/tex]
Distance ≠ 6. So option B is incorrect.
Option C: (x1,y1) = (8,1) , (x2,y2) = (1,1)
⇒ [tex]d=\sqrt{(1-8)^{2} +(1-1)^{2} }[/tex]
⇒ [tex]d=\sqrt{(-7)^{2} +(0)^{2} }[/tex]
⇒ [tex]d=\sqrt{49}[/tex]
⇒ [tex]d=7[/tex]
Distance ≠ 6. So option C is incorrect.
Option D: (x1,y1) = (7,2) , (x2,y2) = (1,2)
⇒ [tex]d=\sqrt{(1-7)^{2} +(2-2)^{2} }[/tex]
⇒ [tex]d=\sqrt{(-6)^{2} +(0)^{2} }[/tex]
⇒ [tex]d=\sqrt{36}[/tex]
⇒ [tex]d=6[/tex]
Distance = 6. So option D is correct.
Hence we can conclude that option (D) points (7,2) (1,2) are separated by distance of 6 units.
