A flag pole that is 20 feet tall casts a shadow 8 feet long.
At the same time of day, a building casts a shadow 25
feet long. How tall is the building?
Answer:
62.5 ft
Step-by-step explanation:
→You can set up a proportion, like so:
[tex]\frac{20}{8} =\frac{x}{25}[/tex]
→Cross multiply:
[tex]\frac{500}{8x}[/tex]
→Divide 500 by 8:
x = 62.5
Answer:
62.5 feet
Step-by-step explanation:
8/20
25/x
25*20/8 = x
x = 62.5
Find the value of x in each case. Give reasons to justify your solutions! NEEDED ASAP

Andrew pays a monthly membership fee of $10 at his gym. Each time he uses the gym, he pays $5. Last month, Andrew
spent a total of $65 for membership and gym use. If the equation 10+5x = 85 models the situation, how many times did he
use the gym last month?
11
O 12

Answer:
11
Step-by-step explanation:
11x5+10=65
Answer: 11 on edge
Step-by-step explanation:
subtract 10 from both sides of the equation to get: 5x=55
then, divide both sides by 5 to get: x=11
so he used the gym 11 times last month!
Hope this helps have a great day!

Answer:
c
Step-by-step explanation:
you know what output you get from the input.
For example, you know that if you put in -5, you get -2, or if you put in 4, you get -2.
Even though there are two inputs for one output, it is still a function.
------------------------------------------------------------------------
If there are two outputs for one input, it is not a function.
For example, on d, when -5 is an input, you don't know if you're going to get 3 or 7. So, it's not a function.

the ratio of the cost of one meter of polyester fabric to the cost of one meter of one silk is 2:9 complete the table of costs
Answer:
Polyester Fabric = 4 || 8 || 16 || 22
Silk Fabric = 18 || 36 || 72 || 99
Step-by-step explanation:
Given:
The above table
Ratio; Polyester Fabric : Silk = 2:9
Required
Complete the above table
Provided that the ratio of the cost of one meter of polyester fabric to the cost of one meter of one silk is 2:9;
To complete rows of polyester fabric
We simply multiply cost by ratio of polyester fabric ratio (2)
To complete rows of silk fabric
We simply multiply cost by ratio of silk fabric ratio (9)
This is as follows:
When length = 2m
Polyester Fabric = 2 * 2 = 4
Silk Fabric = 2 * 9 = 18
When length = 4m
Polyester Fabric = 4 * 2 = 8
Silk Fabric = 4 * 9 = 36
When length = 8m
Polyester Fabric = 8 * 2 = 16
Silk Fabric = 8 * 9 = 72
When length = 11m
Polyester Fabric = 11 * 2 = 22
Silk Fabric = 11 * 9 = 99
Hence, the complete table is as follows:
Polyester Fabric = 4 || 8 || 16 || 22
Silk Fabric = 18 || 36 || 72 || 99
Can someone help me with this question?
The one-year survival rate for pancreatic cancer is 20%. Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year. What is the probability of that happening.
Answer:
The required probability is 0.0155.
Step-by-step explanation:
We are given that the one-year survival rate for pancreatic cancer is 20%.
Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year.
The above situation can be represented through binomial distribution;
[tex]P(X=r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r} ; x = 0,1,2,3,......[/tex]
where, n = number of trials (samples) taken = 12 people
r = number of success = 6 survived
p = probability of success which in our question is probability of
one-year survival rate for pancreatic cancer, i.e; p = 20%
Let X = Number of people survived one year
So, X ~ Binom(n = 12 , p = 0.20)
Now, the probability that 6 survived one year is given by = P(X = 6)
P(X = 6) = [tex]\binom{12}{6} \times 0.20^{6} \times (1-0.20)^{12-6}[/tex]
= [tex]924 \times 0.20^{6} \times 0.80^{6}[/tex]
= 0.0155
At a charity raffle event they are giving out tickets labeled 1 through 10 when people come through the doors. If you are given an even-numbered ticket, you are given a prize at the end of the evening. The table shows the results of 500 guests. What is the relative frequency for the guests who will receive a prize? Ticket Number 1 2 3 4 5 6 7 8 9 10 Frequency 48 42 41 56 67 43 39 41 55 68
Answer:
Relative frequency for guest who will win the prize:
Relative frequency = 50%
Step-by-step explanation:
Total No. of guest = 500
No. of Guests with even-numbered tickets:
Ticket NO. 2 = 42
Ticket NO. 4 = 56
Ticket NO. 6 = 43
Ticket NO. 8 = 41
Ticket NO. 10 = 68
Total No. of Guest with even-numbered ticket = 42+56+43+41+68
Total No. of Guest with even-numbered ticket = 250
So.
Relative frequency = (frequency of desirable event/ total frequency) · 100
Relative frequency = (250/500)· 100
Relative frequency = 50%

Answer:
2/8 or 1/4
Step-by-step explanation:
there are two blues
and there are 8 in total
so its 2/8
Answer:
1/4 = 25% chance.
Step-by-step explanation:
The probability of an event is equal to the amount of favorable outcomes divided by the total amount of outcomes.
There are 2 favorable outcomes (spinning blue). There are a total of 8 locations where the spinner can land.
We can say that 2/8 = 1/4 = 25% chance of spinning blue.

x^2 + 4x = 6
solve by completing the square plz show step by step
Answer:
x = -2 ±sqrt( 10)
Step-by-step explanation:
x^2 + 4x = 6
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 =4
Add this to each side
x^2 + 4x+4 = 6+4
Take the 4/2 term which is the factor inside the (x+ )^2
(x+2)^2 = 10
Take the square root of each side
sqrt((x+2)^2) =±sqrt( 10)
x+2 = ±sqrt( 10)
Subtract 2 from each side
x+2-2 = -2±sqrt( 10)
x = -2 ±sqrt( 10)
Answer:
x= +/- \sqrt(10) - 2
Step-by-step explanation:
use the formula (b/2) in order to create a new term.
Solve for x by using the term to complete the square.

what’s the midsegment
Answer:
17 units
Step-by-step explanation:
The midsegment of a triangle theorem states that:
The midsegment is 1/2 of it's parallel side.
So,
6x + 5 = 1/2(4x + 26)
6x + 5 = 2x + 13
6x - 2x + 5 = 13
4x + 5 = 13
4x = 13 - 5
4x = 8
x = 8 ÷ 4
x = 2
Substitute x to the midsegment.
6x + 5
6(2) + 5
12 + 5
17
Hello
Here is the answer:
A midsegment of a triangle is a segment connecting the midpoints of two sides of a triangle. It is always parallel to the third side, and the length of the midsegment is half the length of the third side.

Find the volume of a pyramid with a square base, where the area of the base is
12.7 ft- and the height of the pyramid is 17.8 ft. Round your answer to the nearest
tenth of a cubic foot.
Answer:
Volume, [tex]V= 75.35\ \text{feet}^3[/tex]
Step-by-step explanation:
We have,
Area of the base of of a pyramid with a square base is 12.7 ft
Height of the pyramid is 17.8 ft
It is required to find the volume of of a pyramid with a square base.
The formula used to find the volume of a pyramid with a square base is given by :
[tex]V=\dfrac{1}{3}Ah[/tex]
Plugging all the values in above formula
[tex]V=\dfrac{1}{3}\times 12.7\times 17.8\\\\V=75.35\ \text{feet}^3[/tex]
So, the volume of a pyramid is [tex]75.35\ \text{feet}^3[/tex].
Answer: 75.4 ft^3 when rounded
Step-by-step explanation:
Volume of Pyramid V=1/3BH
Area of base= 12.7
h=17.8
V=1/3 (12.7)(17.8)
V=75.353333
V=75.4 ft^3

Answer:
c . Quadratic binomial
Step-by-step explanation:
a qudratic expression is always in form of ax²+bx + c while a quadratic trinomial is in the form of ax³+bx²+cx+d .
I hope it helps
Answer:
c.) quadratic binomial
Step-by-step explanation:
Quadratic equation:
ax² + bx + c
The polynomial is in this form and like all quadratics forms a parabola, a u-shape, when graphed. Therefore, it is a quadratic equation.
Binomial = an expression with two terms
This polynomial has three terms: x², and 5x, making it a quadratic binomial.
solve the system and the value of y 3x-5y=-35 2x-5y=-30
Answer:
Step-by-step explanation:
3x - 5y = -35
2x - 5y = -30
3x - 5y = -35
-2x + 5y = 30
x = -5
3(-5) -5y = -35
-15 - 5y = -35
-5y = -20
y = 4
Answer: It is A. 4
Step-by-step explanation:3x - 5y = -35
2x - 5y = -30
3x - 5y = -35
-2x + 5y = 30
x = -5
3(-5) -5y = -35
-15 - 5y = -35
-5y = -20
y = 4

Need help...with this graph
Answer:
The graph with coordinates x6,y8
Step-by-step explanation:
The ratio of red marbles to blue marbles in a bag is 2 to 5. If there are 60
more blue marbles than red marbles in the bag, how many marbles are
there all together?
Answer:
140
Step-by-step explanation:
Let's call the red and blue marbles 2x and 5x. We know that 5x = 2x + 60, so x = 20. The sum of all marbles in the bag is 2x + 5x = 7x which is 7 * 20 = 140 marbles. Hope this helps!
Answer:
84 in all.
Step-by-step explanation:
if there are 2 red marbles to every 5 marble than 60 / 5 = 12, 12 x 2 = 24 + 60 = 84.
Please help me with my algebra.
Answer:
(8, -1)
Step-by-step explanation:
To use elimination, we can add the two equations together to eliminate the y:
x-y = 9
x+y = 7
x + x -y + y = 16
2x = 16
x = 8
Plug that back into the original equation to get:
8-y = 9
y = -1
So the ordered pair is (8, -1)
