Please help! i really need help with this! question is below!
Step-by-step explanation:
Area of the square:
a^2: 4^2=16in^2
Area of the circle:
πr^2: π(4.5)^2= 63.6
Area of white part:
63.6 - 16 = 47.6
Probability of landing on square:
16/63.6 = 0.25
Probability of landing on white part:
63.6/16 = 3.975

Express each of the following in the form
[tex] {7}^{x} [/tex]
a)
[tex] \sqrt[5]{7} [/tex]
b)
[tex] \frac{1}{ \sqrt[7]{7} } [/tex]
Answer:
Explanation:
Answers:
a) [tex]7^{1/5}[/tex]b) [tex]7^{-1/7}[/tex]Each answer has 7 as the base and a fraction as an exponent.
==========================================================
Explanation:
One useful rule here is that [tex]\sqrt[n]{x^m} = x^{m/n}[/tex]. The fraction m/n is the exponent for the base x. Note how the index of the root (n) becomes the denominator of the fraction m/n. So for example if we had n = 3, then we'd be dealing with a cube root.
For part a), we have x = 7, m = 1 and n = 5 to get
[tex]\sqrt[n]{x^m}=x^{m/n}\\\\\sqrt[5]{7^1}=7^{1/5}\\\\\sqrt[5]{7}=7^{1/5}\\\\[/tex]
-----------------
Part b) is the same idea
We would find that
[tex]\sqrt[n]{x^m}=x^{m/n}\\\\\sqrt[7]{7^1}=7^{1/7}\\\\\sqrt[7]{7}=7^{1/7}\\\\[/tex]
Then apply the reciprocal to both sides. This is the same as raising both sides to the exponent -1
[tex]\sqrt[7]{7}=7^{1/7}\\\\\left(\sqrt[7]{7}\right)^{-1}=\left(7^{1/7}\right)^{-1}\\\\\frac{1}{\sqrt[7]{7}}=7^{1/7*(-1)}\\\\\frac{1}{\sqrt[7]{7}}=7^{-1/7}\\\\[/tex]
You could also use the rule that x^(-y) = 1/(x^y) when dealing with negative exponents.
In the second to last step shown above, I used the rule (x^y)^z = x^(y*z) on the right hand side.

The base area of a square-based prism is 25 ft squared. One of the lateral faces of the prism is 30 ft squared. What is the surface area of the prism?
Answer:
170 ft²Step-by-step explanation:
Surface area = 4*lateral faces + 2*bases
A = 4*30 + 2*25 = 170 ft²Which set of numbers is ordered from greatest to least?
A. -6, -10, 0,3
B.-7, -5, 2,6
C. 4, 3, -2,-6
D.-3, -6, 9, 11
Answer:
C
Step-by-step explanation:
Positives are bigger than negatives, so the highest is 4 and the lowest is Negative 6.
Answer:
c is the answer
Step-by-step explanation:
because when the number is negative it's lowe than a positive number and the answer "c" has the first number as a positive which that number is the greatest out of all of them in that answer

The area of a rectangular
driveway is 2x2 + 15x + 25.
The width of the driveway is
x + 5. What is the length of
the driveway?
Answer:
2x+5
Step-by-step explanation:
Okay so lets first factor 2x^2+15x+25
2*25=50
10+5=15
10*5=15
(x+10/2)(x+5/2)
=(x+5)(2x+5)
we know that the width is x+5 so that means the length has to be 2x+5
In ΔCDE, the measure of ∠E=90°, the measure of ∠C=70°, and DE = 12 feet. Find the length of CD to the nearest tenth of a foot
Answer:
[tex]CD = 4.4ft[/tex]
Step-by-step explanation:
Given
[tex]DE = 12[/tex]
[tex]\angle C = 70^\circ[/tex]
Required
Find CD
This question is represented with the attached triangle
To solve CD, we make use of tan formula.
[tex]tan(70) = \frac{DE}{CD}[/tex]
Substitute 12 for DE
[tex]tan(70) = \frac{12}{CD}[/tex]
Make CD the subject
[tex]CD = \frac{12}{tan(70)}[/tex]
[tex]CD = \frac{12}{2.7475}[/tex]
[tex]CD = 4.4ft[/tex] --- approximated

Answer:
Part A: d ≥ 500
Part B: d must be over or equal to 500 but can go infinity at 500+
Step-by-step explanation:
Part A:
≥ stands for "at least" and d has to be "at least" 500,
hence d ≥ 500

The odometer in a car measures the number of miles driven by the car since it was made. During a trip, the odometer reading in Anita’s car is modeled by the function y=9500+55x, where x represents the number of hours driven during the trip and y represents the odometer reading in miles.
Part A
What is the meaning of the rate of change in this function?
The number of miles driven each hour during the trip.
The total number of miles driven at the beginning of the trip.
The total number of miles driven at the end of the trip.
The number of miles driven during the trip.
Question 2
Part B
What was the odometer reading, in miles, before Anita’s trip?
Answer:
Step-by-step explanation:
Part A
The units on 9500 must be miles. So if x is time, then 55 must be the rate at which she travels ie 55 miles per hour. So the answer must be A.
Part B
The trip began when the time was zero. Therefore x is zero. What remains is the mileage on the odometer when x = 0. The answer must be 1950.

A circle is drawn within a square as shown. What is the best approximation for the area of the shaded region? Use 3.14 to approximate pi. There is a shaded square with a circle inside it and there is a 28 in. Mark on the side of the square.
Answer:
168.168 square inches
Step-by-step explanation:
Given data
From the question, we can deduce that the side of the square is 28in
Hence the area of the square is
Area= 28^2
Area= 784 square inches
Also, the diameter of the circle is 28 in
The radius = 14 in
Area of circle= πr^2
Area= 3.142*14^2
Area= 3.142* 196
Area= 615.832 square inches
Therefore the area of the shaded region is
= Area of Square - Area of Circle
= 784-615.832
=168.168 square inches
