Answer:
[tex]h = 7.69cm[/tex]
Step-by-step explanation:
Given
[tex]Volume = 455cm^3[/tex]
[tex]l = h[/tex]
Where:
[tex]h \to height[/tex]
[tex]l \to base\ length[/tex]
Required
The height
The volume is calculated as:
[tex]Volume = l^2 * h[/tex]
This gives:
[tex]Volume = h^2 * h[/tex]
[tex]Volume = h^3[/tex]
Rewrite as:
[tex]h^3 =Volume[/tex]
So, we have:
[tex]h^3 = 455cm^3[/tex]
Take cube roots
[tex]h = \sqrt[3]{455cm^3}[/tex]
[tex]h = 7.69cm[/tex] --- approximated

A 6-digit PIN number is selected. What it the probability that there are no repeated digits?
The probability that no numbers are repeated is
Write your answer in decimal form, rounded to the nearest thousandth.
Submit Question
Answer:
we got 10 digits to choose from for the first digit, 9 for the second and so on
[tex]10 \times 9 \times 8 \times 7 \times 6 \times 5[/tex]
scenarios that got no repeated digits.
the total number of possible PINs with 6 digits is
[tex]10 \times 10 \times 10 \times 10 \times 10 \times 10[/tex]
or just 10⁶
so the fraction we are looking for is the number of valid states decided by all possible states.
[tex] \frac{10 \times 9 \times 8 \times 7 \times 6 \times 5}{ {10}^{6} } [/tex]
=0.1512
rounded to the nearest thousandth it's
0.151
(actually, I didn't expect the probability to be around 15 percent)
hope it helps. asked question whenever you like

A roundabout is a one-way circular intersection.
About how many feet would a car travel if it drove
once around the roundabout? Round to the
nearest foot.
Answer:
[tex]471\:\mathrm{ft}[/tex]
Step-by-step explanation:
In one full rotation around the roundabout, the car is travelling a distance equal to the circumference, or the perimeter, of the circle. The circumference of a circle with radius [tex]r[/tex] is given by [tex]C=2r\pi[/tex]. In the diagram, the diameter is labelled 150 feet. By definition, the radius of a circle is exactly half of the diameter of the circle. Therefore, the radius must be [tex]\frac{150}{2}=75[/tex] feet. Thus, the car would travel [tex]2\cdot 75\cdot \pi=471.238898038=\boxed{471\:\mathrm{ft}}[/tex]
a walking path across a park is repersented by the equation y=-2x-7. A new path will be built perpendicular to this path the paths will intercept at the point (-2,-3) identify the equation that represents the new path
Answer:
y + 3 = (1/2)(x + 2)
Step-by-step explanation:
The slope of the original path is -2. Any new path perpendicular to this one will have a slope which is the negative reciprocal of -2, which here is 1/2.
Use the point-slope formula y - k = m(x - h):
y - (-3) = (1/2)(x - (-2)), or
y + 3 = (1/2)(x + 2) represents the new path.
f(x+k) what is the value of k
Answer:
k = -3
Hope this helps!
Answer:
Step-by-step explanation:
f(x+k) is a horizontal shift of -k units.
Since the vertex went from 1 to -2, k = 3.
Question 7
Find the volume.
Answer:
A: 686π≈2,156
Step-by-step explanation:
First, you need to find the area of the circle then times that by 14.
π[tex]r^{2}[/tex] Formula for the area of a circle
π[tex]7^{2}[/tex] r stands for radius, so you divide the diameter by 2 and get 7.
π49 This is the area of the circle
π49×14 Now multiply by 14
=686π This is your answer.
=2155.13256 When you times it by pi this is what you get
=2156 This is your answer if you want it rounded up

square roots and solving quadratics
Answer:
x = ±10
Step-by-step explanation:
4x² - 400 = 0
Add 400 to both sides
4x² = 400
Divide both sides by 4
x² = 100
Take the square root of both sides
x = ±10

Rounding in the calculation of monthly interest rates is discouraged. Such rounding can lead to answers different from those presented here. For long-term loans, the differences may be pronounced.

A) Abdul invests 400$ at 6.05% per year simple interest, calculate how much interest Abdul receives
B) Samia receives 400$ for 2 years at 6% per year compound interest, give your answer in 2 decimal places
Answer:
$24.20
amount invested = $356
Interest = $44
Step-by-step explanation:
Samia receives a total amount of 400$ for 2 years at 6% per year compound interest, give your answer in 2 decimal places
Simples interest = amount invested x time x interest rate
400 x 0.065 x 1 = $24.20
b. interest = amount received - amount invested
Amount invested = amount received / (1 + r)^n
r = interest rate
n = number of years
400 / (1.06)^2 = 356
Interest = 400 - 356 = $44

Value-Mart had 2,371 customers last week. Each customer donated $2 to the food bank. How much money did Value-Mart raise for the food bank? *
9514 1404 393
Answer:
$4,742
Step-by-step explanation:
The total of donations is the product of the number of donations and the amount of each.
(2371 customers) × ($2/customer) = $(2371×2) = $4742
Value-mart raised $4,742 for the food bank last week.
_____
You could find the total donated by adding the 2371 donations. Multiplication was invented to make repeated addition easier. When the sum consists of 2371 instances of $2, we can find the total by multiplying $2 × 2371.

What is M
Put your answer in the box
°
Answer:
2
Step-by-step explanation:
9m + 25m + 22 = 90
34m = 90 - 22
34m = 68
m = 68 / 34
m = 2
Answer:
m = 2
Step-by-step explanation:
GLI forms a 90 degree angle
Set your formula up as
90 = 9m + 25m + 22
90 - 22 = 34m
68 = 34m
68/34 = m
2 = m
Can someone help me?
Answer:
The slope is 2
Step-by-step explanation:
Slope formula:
m=(y2-y1)/(x2-x1)
Given:
y2 = -10
y1 = -6
x2 = 2
x1 = 4
Work:
m=(y2-y1)/(x2-x1)
m=(-10 + 6)/(2 - 4)
m= (-4)/(-2)
m = 2

Answer:
C
Step-by-step explanation:
The graph of the absolute value function y = | x | has its vertex at the origin and has the shape V
The graph here is the absolute value translated vertically 3 units down, so
y = | x | - 3 → C
Hi there!
»»————- ★ ————-««
I believe your answer is:
[tex]c) |x| - 3[/tex]
»»————- ★ ————-««
Here’s why:
The graph given is an absolute value function. This eliminates options A and B, since they are not absolute value functions. The graph shows the parent function of f(x) = |x| that is shifted 3 units down. This can be written as f(x) = |x| - 3.⸻⸻⸻⸻
Option C should be the correct answer.

Answer:
21
Step-by-step explanation:
4x-2=3x+19
4x-3x=19+2
x=21
Answer:
x = 21
Step-by-step explanation:
These are opposite angles and are therefore equal.
Equate the two angles to solve for x.
4x-2 = 3x+19
subtract 3x-2 from either side (i.e. numbers on the left, and variables on the right)
4x-2 -(3x-2) = 3x+19 - (3x-2)
x = 21
check: 4x-2= 82, 3x+19=82, so solution is good.

Find the surface area of the
prism.
Answer:
D. 464 ft²
Step-by-step explanation:
Area of trapezoidal prism = h(b + d) + l(a + b + c + d)
Where,
h = 4 ft
a = 5 ft
b = 6 ft
c = 5 ft
d = 12 ft
l = 14 ft
Plug in the values into the formula
Area of trapezoidal prism = 4(6 + 12) + 14(5 + 6 + 5 + 12)
= 4(18) + 14(28)
= 72 + 392
= 464 ft²

A man leaves the town of Elmsville at 8:00 am and drives to Oak City at a constant rate of 50 miles per hour. Two hours later, a woman leaves Elmsville following the same route to Oak City. The man and woman arrive in Oak City at 3:00 p.m. What was the rate of the woman
Answer: 70 mph
Step-by-step explanation:
Given
A man leaves the town of Elmsville at 8:00 am and reach oak city at 3 Pm
Rate of driving is 50 miles per hour
time taken by man [tex]t=7\ hr[/tex]
Woman leaves 2 hour later and reach by 3 Pm, so time taken is [tex]5\ hr[/tex]
Distance traveled by both the person is same
[tex]\therefore 50\times 7=v\times 5\quad[v=\text{rate of woman}]\\\\\Rightarrow v=\dfrac{50\times 7}{5}\\\\\Rightarrow v=70\ mph[/tex]
Thus , the rate of woman is 70 miles per hour.
