What is the approximate length of the radius, r? Use 3.14 for π. Round to the nearest tenths.
A. 15.4
B. 10.4
C. 35
D. 32.5
Answers
Answer:
10.35
Step-by-step explanation:
c=2[tex]\pi[/tex]r
65=2(3.14)?
Answer:
B. 10.4
Step-by-step explanation:
The formula for the circumference is: 2πr
2πr≈65
Divide both sides by 2
πr=32.5
Divide both sides by π
r≈10.34
The answer that makes most sense is B. 10.4

Water makes about 3/4 of a person’s weight. If a student weighs 100 lbs., how much of his weigh is water?
Answers
Answer:
75 pounds
Step-by-step explanation:
To solve this problem, find 3/4 of 100.
To multiply fractions, multiply the numerators by each other and the denominators by each other.
3/4 * 100/1
Evaluating 3*100 and 4*1, the fraction becomes 300/4.
Now, divide 300 by 4 to get the final answer. 300/4 = 75. Therefore, 75 pounds of the students weight is water.
Answer:
75 lbs
Step-by-step explanation:
3/4 * 100
3 * 100/4
3 *25
75 lbs is water
A fast food chain surveyed a random sample of students to determine what pizza they prefer. Cheese pizza was preferred by 40 students. Pepperoni pizza was preferred by 28 students. Based on the results, how many of the 340 students can be expected to prefer cheese pizza?
Answers
Answer:
11.76
Step-by-step explanation:
We are given that,
Total number of students = 340
Students that prefer cheese pizza = 40
Students that prefer pepperoni pizza = 28
Thus, we get that,
The proportion of students that prefers cheese pizza =
i.e. The proportion of the students preferring cheese pizza = 0.1176 = 11.76%
Hence, 11.76% of the students prefer cheese pizza.

The value of an antique can be predicted by the expression 250 * (1.12) ^ t where is the number of years since 2014. What does the value 250 represent?
Answers
Answer:
mark brainlyest and I will
The value 250 represents the predicted value of antique in year 2014.
Given Expression,
[tex]250\times(1.12)^{t}[/tex]
Here [tex]t[/tex] represents the no. of years since 2014.
Now clearly 250 shows here the predicted price of the antique in year 2014 and [tex](1.12)^t[/tex] shows how much percent the product is increasing over the year.
Hence the value 250 represents the predicted value of antique in year 2014.

In ABC, A is a right angle. And B = 45 degrees. What is the length of BC
A) 54ft
B) 17√ 3ft
C) 17√ 2ft
D) 17ft
Answers
Given that this is an isosceles triangle (triangle with two congruent sides) and is 45 degrees on both sides then this would be considered a 45-45-90 triangle
The rule for this type of triangle is that going from a congruent side (for example segment AC) to BC would result in your multiply by the square root of 2.
Multiplying square roots and whole numbers are fairly easy, just combine it like multiply with a variable. Since the rule for a 45-45-90 triangle is to multiply the side length by the square root of 2 to get the hypotenuse then you would multiply 17 by the square root of 2 which will give you answer choice C.
If you encounter a similar problem like this but with the hypotenuse to the side length then you would do the OPPOSITE of multiplying by the square root of 2 (which would be dividing the hypotenuse by the square root of 2).
h(x) = x2 – 3
If the graph of h is translated vertically upward by 4 units, it becomes the graph of a function g.
Find the expression for g(x).
Answers
Answer:
[tex]g(x)=x^2+1[/tex]
Step-by-step explanation:
The given function is
[tex]h(x)=x^2-3[/tex]
If a function translated vertically upward by p units, then we need to add p in the function value to get the new function.
It is given that if the graph of h is translated vertically upward by 4 units, it becomes the graph of a function g. So,
[tex]g(x)=h(x)+4[/tex]
[tex]g(x)=x^2-3+4[/tex]
On simplification, we get
[tex]g(x)=x^2+1[/tex]
Therefore, the required function is [tex]g(x)=x^2+1[/tex].

Oil is leaking from an oil tanker, and an expanding circle of oil is spreading on the ocean. The radius, r, of the circle measured in inches is modeled by the function r(s)=3 sqrt s, where s is time in seconds. The area of the spill when s=5 seconds is ___ pi square inches.
Answers
Answer:
[tex]Area=45\pi$ square inches[/tex]
Step-by-step explanation:
The radius, r of the expanding circle of oil is modeled by the function:
[tex]r(s)=3\sqrt{s}[/tex], where s is time in seconds.
When s=5
Radius, [tex]r(5)=3\sqrt{5}$ inches[/tex]Area of a circle[tex]=\pi r^2[/tex]
Therefore, area of the oil spill when s=5 seconds is:
[tex]Area=\pi (3\sqrt{5})^2\\=\pi *3^2*(\sqrt{5})^2\\=\pi *9*5\\$Area=45\pi$ square inches[/tex]
The area of the spill when s=5 seconds is 45pi square inches.

Answers
Answer:
First one
Step-by-step explanation:
Variable b is 7 more than variable c:
b = c + 7
Variable b is also 1 less than variable c:
b = c - 1
Answer:
B:
b = c + 7
b = c - 1
Step-by-step explanation:
"Variable b is 7 more than variable c" can be expressed mathematically as
b = c + 7
"Variable b is 1 less than variable c" can be expressed mathematically as
b = c - 1
So the second pair,
b = c + 7
b = c - 1
best models the relationship between b and c
