Answer:
[tex]34in^2[/tex]
Step-by-step explanation:
First, you should find the area of the trapezoid which the formula for that is:
[tex](b1 + b2)h/2[/tex]
So, you will ad up 7in and 3in, and you should get 10in.
Now multiply 10 in by the height which is 5in, so it will be 50in^2. Then you have to divide that by 2 turning it into 25in^2.
For the top part, it is basically a triangle so you just multiply 3 by 6, giving you 18/2 = 9in^2
Add the two together and you should get 34in^2

Mrs. Pascal has a candy jar that contains 5 Jolly Ranchers and 13 jawbreakers. Solve each of the following problems and explain your thinking.
1) Suppose that you have a new candy jar with the same ratio of Jolly Ranchers to jawbreakers that Mrs. Pascal had but it contains 100 Jolly Ranchers. How many jawbreakers would you have?
Answers
Answer:
260 jawbreakers
Step-by-step explanation:
The ratio is 5:13 so if the value of Jolly ranchers increased 20x then the number of jawbreakers would also increase by 20x. There are 260 jawbreakers.
A scale model NASA is working on for the space shuttle is built in the ratio of 1:15, meaning the actual space shuttle is 15 times larger. If the rocket fuel container on the model is 5 inches long, how many inches long is the rocket fuel container on the actual space shuttle?
Answers
The rocket fuel container on the actual shuttle is 75 in. long
Ratio of the model: actual shuttle
1:15
Ratio of fuel tank on model: fuel tank on actual shuttle
5: (unknown)
Multiply 5 by 15 to find the unknown value.
5 x 15 = 75 inches long
Answer: 75 inches
Step-by-step explanation:
From the question, we are informed that a scale model NASA is working on for the space shuttle is built in the ratio of 1:15.
If the rocket fuel container on the model is 5 inches long, the number of inches long is the rocket fuel container on the actual space shuttle will then be:
= 5 × 15.
= 75 inches

Problem to solve:
Suppose you were to drop a stone down a well. A falling object obeys the equation s=16(t1)2 , where s is the distance fallen in feet and t is the time in seconds. Sound waves travel at a speed of about 1100 ft/sec, and the time it takes to travel a distance s is t2=s1100 . The total time it takes for you to hear the stone hit the water below equals the time it spent falling plus the time it takes the sound to reach your ear. What is the distance to the water's surface in the well if you hear the stone hit the water 4 seconds after dropping the stone?
Answers
Answer:
228.64 ft
Step-by-step explanation:
Given that the total time, t it takes for you to hear the stone hit the water below equals the time it spent falling, t1 plus the time it takes the sound to reach your ear t2.
Given that t = 4s and t = t1 + t2.
So t1 + t2 = 4 (1)
Also s = 16(t1)² and t2 = s/1100
Thus t2 = 16(t1)²/1000
From (1), t2 = 4 - t1
So 4 - t1 = 0.016(t1)²
0.016(t1)² + t1 - 4 = 0
(t1)² + 62.5t1 - 250 = 0
Using the quadratic formula to find t1,
[tex]t1 = \frac{-1 +/- \sqrt{1^{2} - 4 X -4 X 0.016} }{2 X 0.016}\\t1 = \frac{-1 +/- \sqrt{1 + 0.256} }{0.032} \\t1 = \frac{-1 +/- \sqrt{1.256} }{0.032} \\t1 = \frac{-1 +/- {1.121} }{0.032} \\t1 = \frac{-1 + 1.121 }{0.032} or t1 = \frac{-1 - 1.121 }{0.032}\\t1 = 0.121/0.032 or -2.121/0.032\\t1 = 3.78 s or -66.28 s[/tex]
Since t1 cannot be negative, t1 = 3.78 s
So, s = 16(t1)²
= 16(3.78)²
= 16(14.29)
= 228.64 ft

Ava owns a small business selling clothing. She knows that in the last week 35 customers paid cash, 13 customers used a debit card, and 5 customers used a credit card. Based on these results, express the probability that the next customer will pay with cash as a fraction in simplest form.
Answers
Answer:
Why dont you just do the steps
Step-by-step explanation:
First you have to add it all together then take your second number, aka 35 which gives you
35/53 which then you just get your fraction from that
Probability of next customer paying cash is [tex]\frac{35}{53}[/tex].
Given that,
Number of customer paid cash (a) is 35.Number of customer paid by debit card (b) is 13.Number of customer paid by credit card (c) is 5.According to the scenario, computation of the given data are as follows,
Probability of next customer paying cash = [tex]\frac{a}{(a+b+c)}[/tex]
By putting the value, we get
Probability = [tex]\frac{35}{(35 + 13 + 5)}[/tex]
= [tex]\frac{35}{53}[/tex]

This is simple:
First of all, let us take the first equation:= 4x - 2y = 8
Put x = 0
= 4 ( 0) - 2 y = 8
= 0 - 2y = 8
= -2y = 8
= y = 8/-2
= y = - 4
So, the solution will be ( 0, -4)
For second equation,= y = ½ x + 2
Put x = 0
= y = ½ × 0 + 2
= y = 0 + 2
= y = 2
So, the solution will be ( 0, 2 ).
Now plot these points on the graph.Note*- I have taken x = 0 for easy calculation, you can take any number of your choice._________________________Two identical number cubes are shown in the picture.

Answers
Answer:
They are both identical cubes which makes it much easier.
Work out the volume for just one first.
The formula for volume is:
l x w x h
However, since it is a cube, all lengths are the same.
3 x 3 x 3 = 27
Now multiply it by 2 to get the volume of both combined:
27 x 2 = 54.
In short, your answer is 54cm 3

BRAINLIEST WILL BE GIVEN
Answers
Answer:
10 secs for Jane and Dien is 15 secs
Step-by-step explanation:
Using the together rate, it is found that Jane can eat a pizza in 10 seconds and Dien in 15 seconds.
What is the together rate?It is the sum of each separate rate.
In this problem, the rates are:
Dien's rate: 1/x+5.Jane's rate: 1/x.Together rate: (2/3)/4 = 1/6Hence:
[tex]\frac{1}{x + 5} + \frac{1}{x} = \frac{1}{6}[/tex]
[tex]\frac{x + x + 5}{x(x+5)} = \frac{1}{6}[/tex]
[tex]\frac{2x + 5}{x^2 + 5x} = \frac{1}{6}[/tex]
[tex]x^2 - 7x - 30 = 0[/tex]
[tex](x - 10)(x + 3) = 0[/tex]
The positive solution is x = 10, hence Jane can eat a pizza in 10 seconds and Dien in 15 seconds.

PROBLEM SOLVING When a plant or animal dies, it stops acquiring carbon-14 from the atmosphere. The amount y in grams) of carbon-14 in the body of an organism after t years is y= a(0.5)^t/5730, where a is the initial amount (in grams). What percent of the carbon-14 is released each year? Round your answer to the nearest hundredth.
Answers
Answer:
0.01%
Step-by-step explanation:
y=a (0.5)^t/5730
y=a [(0.5)^t/5730]
when you put 0.5^1/5730
it'll give you 0.99
The "equation" is y=a(1-r)^t
so 1-0.99 is 0.01
The percent of carbon-14 released each year will be 50.
What is an exponent?Consider the function:
y = a (1 ± r) ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %.
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %.
The equation is given below.
[tex]\rm y= a \left ( 0.5 \right )^{t/5730}[/tex]
Where 'a' is the initial amount (in grams) and 't' represents the number of years.
The equation is also written as,
[tex]\rm y= a \left ( 0.5 \right )^{t/5730}\\\\\rm y= a \left ( 1 - 0.5 \right )^{t/5730}[/tex]
The percent of carbon-14 released each year will be 50.
