A rectangle has an area of 159.1m2. One of the sides is 3.7m in length. Work out the perimeter of the rectangle.
Answers
Answer:
93.4 mSolution,
Area of rectangle=159.1 m^2
Length=3.7 m
Breadth=?
Now,
\(area \: of \: rectangle = l \times b \\ or \: 159.1 = 3.7 \times b \\ or \: 159.1 = 3.7b \\ or \: b = \frac{159.1}{3.7} \\ b = 43 \: m\)
Again,
Perimeter of rectangle:
\(2(l + b) \\ = 2(3.7 + 43) \\ = 2 \times 46.7 \\ = 93.4 \: m\)
Hope this helps...
Good luck on your assignment..

Graph m(x) on a coordinate plane to determine whether or not the function represents a direct variation. In complete sentences, describe your conclusion and reasoning. Include your graph in your answer.
Answers
Answer:
m(x) = 1.5x . . . . direct variation
Step-by-step explanation:
You want to know if the function m(x) represents direct variation, given a table of values.
Direct variationAn equation for direct variation is ...
y = kx
where k is a constant that can be found as the ratio of any (x, y) pair:
k = y/x
k = -1.5/-1 = 1.5/1 = 3/2 = 6/4 = 1.5
The ratios are constant, hence m(x) is direct variation with a constant of variation of 1.5.
GraphThe graph of direct variation is a straight line through the origin. The given points lie on such a line.

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

1. In 2014, the attendance at Jefferson School's Fall Festival was 650. In 2015, the attendance was 575. What was the percent change in attendance from 2014 to 2015? Round to the nearest whole percent.
Answers
Answer:
11%
Step-by-step explanation:
First you need to find the difference between 575 and 650. That's 75 people. 75 is around 11% of 650, so 11% is the rounded whole percent.
Answer:
11.5
Step-by-step explanation:
650-575 = 75
11.54 = 75 out of 650

William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
What is the probability that one of the events William worked on last year, selected at random, was an anniversary party?
Write your answer as a fraction or whole number.
Answers
Answer:
hello
Step-by-step explanation:
The required probability that William worked on last year was an anniversary party is 1/ 36.
As mentioned in the quesiton,
William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Total sample space = 26 + 10 = 36
Number of favorable outcomes = 1
the probability that William worked on last year is was an anniversary party,
= Favorable outcome/sample space
= 1 / 36
Thus, the required probability that William worked last year is 1/ 36.

Answers
Answer:
the answer would be spinning a 3 and getting an even number on the number cube. read why below!
Step-by-step explanation:
because the spinner presents three options (two 2s, a 3 and a 1), there is a 50% chance that he will spin a 2. the spinner has to be able to represent his chances of having mr. muller as his science teacher though, because there is only a 25% chance that he will spin a 1 or a 3.
the number cube might be difficult to understand, but because there are 3 even numbers and 3 odd numbers, the chances of rolling an even or an odd number are equal: 50/50 chance, which represents his chances of having mrs. waugh as a teacher.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Step-by-step explanation:
A). An investment account earns 2.8% simple interest.
Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.
B). The price of a stock varies by 2.8% each week.
Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.
Therefore, the answer is NEITHER.
C). An investment account earns 2.8% compound interest, compounded monthly.
Formula to get the value of the final amount in the account is,
Final value = Initial value × \((1+\frac{.028}{100})^t\)
Here 't' = Duration of investment
