Answer:
The pole is 6 feet tall.
Step-by-step explanation:
The height makes the perpendicular and the shadow makes the base of the triangle in the given question
Pole Mary
Height x 4
Shadows 15 10
If the height is taken along y- axis and shadow is taken along x axis
Then
tan alpha = Perpendicular/ base
for Mary Tan alpha = 4/10
For the pole = tan alpha = x/15
Comparing x/15= 4/10
x= 4*15/10= 60/10= 6
The pole is 6 feet tall.

Joe has 6 frogs, 8 hamsters, 9 goldfish, and 3 snakes. What is the ratio of Joe's frogs and snakes to hamsters?
Answer:
9:8
Step-by-step explanation:
According to the word problem, Joe has 6 frogs, 8 hamsters, 9 goldfish, and 3 snakes.
The question is asking the ratio of Joe's frogs AND snakes TO hamsters.
To find out the ratio of frogs and snakes, add how many frogs there are to how many snakes there are.
6 + 3 = 9.
The last part of the equation should be obvious.
There are 8 hamsters.
Therefore, the ratio of Joe's frogs and snakes to hamsters is 9:8.

if the ratio of type O to non-type O donors at a blood drive was 37:43. how many would be type O out of 300 donors? will try and mark brainliest . please show the work as well
Answer:
Step-by-step explanation:
Proportion of type O donors = 37/(37+43) = 37/80
300 × 37/80 = 138.75
139 donors out of 300 are type O.
A ratio shows us the number of times a number contains another number. The number of type O donors out of 300 is 139.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the ratio of type O to non-type O donors at a blood drive was 37:43. Therefore, the number of type O blood donors be represented by 37x and the number of non-type O blood donors be represented by 43x.
Now, the sum of type and non-type O donor is 300. Therefore, we can write,
37x + 43x = 300
80x = 300
x = 3.75
Further, the Number of type O donors out of 300 can be written as,
Number of type O donors out of 300 = 37x = 37(3.75) = 138.75 ≈ 139
Hence, the number of type O donors out of 300 is 139.

If 3000 is placed in an account at 5% interest and is compounded quarterly for 5 years.How much is in the account at the end of 5 years?
Answer:
FV= $3,846.11
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,000
Number of periods (n)= 5*4= 20 semesters
Interest rate (i)= 0.05/4= 0.0125
To calculate the Future Value, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 3,000*(1.0125^20)
FV= $3,846.11

passes through
0, 0 , 2, 4 , and 4, 0
Answer:
y = -x² + 4xStep-by-step explanation:
The standard form:
y = ax² + bx + cPairs given:
(0, 0), (2, 4), (4, 0)Substitute values of x and y and work out the values of a, b and c.
1. Point (0, 0)
0 = a(0)² + b(0) + c ⇒ c = 02. Point (2, 4)
4 = a(2)² + b(2) ⇒ 4a + 2b = 4 ⇒ 2a + b = 2 ⇒ b = 2 - 2a3. Point (4, 0)
0 = a(4)² + b(4) ⇒ 16a + 4b = 0Substitute b and solve for a:
16a + 4(2 - 2a) = 016a + 8 - 8a = 08a = -8a = -1Find b:
b = 2 - 2(-1) = 2 + 2 = 4The function is:
