WHAT IS THE ANSWER TO #37 And #38 20 Points!

Answers

Answer 1
37.

Call the amount David has, d.
Call the amount Jhumpa has, j.

Jhumpa has $55.
Jhumpa has $21 more than David.
$55 is $21 more than David has, so if you add $21 to David's amount, d, you get Jhumpa's amount, j

j = d + 21

38.

Let the temperature at noon be t.
The temperature fell 16 deg from noon, so you must subtract 16 from the temperature at noon to get the temperature at 3 pm. The temperature at 3 pm was -3 deg.
That means that t minus 16 must equal -3.

t - 16 = -3

At Algorithms Pizza they have the exponential pizza, which is a 24-inch cheese pizza that costs $17.50. Each topping for the pizza costs $2.35. If Connor ordered the exponential pizza and was charged $29.25, how many toppings were on his pizza? Justify your answer by using an algebraic equation to solve this problem step by step

Answers

He got 5 toppings, subtract 29.25 and 17.50, you get 11.75, then divide by 2.35, you get 5.

Answer:

5 toppings.

Step-by-step explanation:

Let there were x toppings on the exponential pizza ordered by Connor.

Then charges for toppings = $2.35x

If the cheese pizza costs = $17.50

Total charges for the pizza = (17.5 + 2.35x)

Total cost of the cheese pizza with toppings = $29.25

Equation to find the number of toppings will be

29.25 = 17.5 + 2.35x

2.35x = 29.25 - 17.5

2.35x = 11.75

x = [tex]\frac{11.75}{2.35}[/tex]

x = 5

Therefore, number of toppings on the pizza will be 5.

Which situation is represented by the inequality? 3x + 5 > 2x + 15

Answers

Final answer:

The inequality 3x + 5 > 2x + 15 represents a situation in which x is greater than 10.

Explanation:

The inequality 3x + 5 > 2x + 15 represents a situation in which one side of the equation is greater than the other. To solve this inequality, we need to isolate x on one side of the equation. Here are the steps:

Subtract 2x from both sides of the equation: 3x + 5 - 2x > 2x + 15 - 2xSimplify both sides of the equation: x + 5 > 15Subtract 5 from both sides of the equation: x + 5 - 5 > 15 - 5Simplify both sides of the equation: x > 10

So, the inequality 3x + 5 > 2x + 15 represents a situation in which x is greater than 10.

Describe a real-world situation that could be modeled by the binding two rational numbers

Answers

The example of real life situations is: The cost of 30 green apples is €60
Rox wants to buy only 5 apples, how much will they cost her?

Cost of 30 green apples is €60.
Cost of 1 green apple = €60/30 = €2
(Using the concept of division of rational numbers)
Now, cost for 5 green apples =5 * €2 = €10

a bag of concrate can be used to make a 5ft by 7ft porch.if you want to make a 20ft by 28ft,porch. how many bags of concreate do you need? the answer is not 4

Answers

Calculate the area of each rectangular:

5x7= 35sqft

20x28= 560sqft

If 1 bag makes 35sqft, 560sqft is how many bags;
This is how I write the equation;

1x bag 35sqft

X 560sqft

Solution: (560x1) : 35 = 16bags

I solved this based on my way of logic. I'd appreciate if you let me know if the answer is correct.

area of 5 x 7 porch = 5*7 = 35 sq. ft.

 area of 20 x 28 porch = 20 *28 = 560 sq. ft.


560 / 35 = 16

 so 16 bags are needed

Answers

 = 4/-12
 = -1/3

answer
slope = -1/3

Answer: The slope of the line is [tex]-\frac{1}{3}[/tex].

Explanation:

From the given graph it is noticed that the line passing through many points.

The coordinates of three given points are (-6,6), (0,4) and (6,2).

If a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], the slope of the lie is defined by,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The line passing through two points (0,4) and (6,2). So the slope of the line is,

[tex]m=\frac{2-4}{6-0}[/tex]

[tex]m=\frac{-2}{6}[/tex]

[tex]m=-\frac{1}{3}[/tex]

Therefore, the slope of the line is [tex]-\frac{1}{3}[/tex].

A cookie recipe for three dozen Caramel peanut butter bars uses 14oz of caramel. How much caramel (to the nearest ounce) should be used to make 120 bars for a cookie exchange

Answers

140oz I believe because you just do 14oz times 10 because one dozen is 12 and 12 times 10 is 120.
Final answer:

To make 120 caramel peanut butter bars, using a recipe that calls for 14 ounces of caramel for 36 bars, one would need 47 ounces of caramel (rounded to the nearest ounce).

Explanation:

Given that a cookie recipe for three dozen caramel peanut butter bars uses 14 ounces of caramel, we need to determine the amount of caramel needed to make 120 bars. Since three dozen bars are equal to 36 bars, we can find how many times the amount of bars in the recipe fits into the desired 120 bars count by dividing 120 by 36.

This gives us 120 / 36 = 3.33. Multiplying this factor by the amount of caramel used for 36 bars gives us the amount needed for 120 bars: 3.33 * 14 ounces = 46.62 ounces. Therefore, 47 ounces of caramel (rounding to the nearest ounce) should be used to make 120 bars for a cookie exchange.

I need help with number 24. It says is it possible that Lauren answered more questions correctly on the second math test than Antoine did? Explain.

Answers

It is, because Lauren may have gotten a incredibly high score on the first test, and a worse one on the second, while Antoine may have gotten a horrible score for the first test.
Final answer:

Calculating the probability of getting more than 75% of answers right with random guessing is unlikely to yield a count higher than 24 correct answers. Therefore it is improbable for Lauren to have answered more questions correctly than Antoine. However, without specific data on Lauren's and Antoine's test results, we cannot say with absolute certainty.

Explanation:

To ascertain if Lauren could have answered more questions correctly on her second math test than Antoine, we need to understand the concept of probability. In this case, we want to find P(x > 24)  which means we want to find out if getting more than 75 percent (or more than 24 correct answers) out of 32 questions is possible. That is, did Lauren score more than 24? However, the probability of getting more than 75 percent of the 32 questions correct when randomly guessing is practically zero. Mathematically, we express this as P(x > 24) = 0.

This suggests obtaining a score higher than 24 is very difficult, and therefore it's unlikely that Lauren answered more questions correctly than Antoine, especially if answering was based on random guessing. However, without specifics about Lauren's or Antoine's performance, we can't say definitively.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
Percentage of correct answer in 1st quiz = 100% - 3/10 × 100% = 70%
Percentage of correct answer in 2nd quiz = 100% - 4/15 × 100% = 77%
