Sherman hopes to get at least a 90 average on his science test. He has one more test before the end of the year. His past test scores are 79, 94, 91, and 92.Write and solve an inequality that represents the situation. What is the lowest score Sherman can get on his final test and reach his? show your work

Answers

(79 + 94 + 91 + 92 + x) / 5 > = 90
(356 + x) / 5 > = 90
356 + x > = 90 * 5
356 + x > = 450
x > = 450 - 356
x > = 94 <=== Sherman can get the lowest score at 94

Answer:

94 points

Step-by-step explanation:

The mean is defined by the sum of the numbers divided by how many numbers there are, so:

[tex]\frac{(79+94+91+92+x)}{5}>=90\\\\\frac{(356+x)}{5}>=90[/tex]

Multiplying both sides by 5

[tex](356+x)>=450[/tex]

Subtracting 356 on both sides:

[tex]x>=94[/tex]

So Sherman has to obtain at least 94 points on his final test in order to get an average of at least 90.

350$ at 3% for 10 years. What Is the
Interest earned?

Answers

If you are using continuous compound interest, the formula is A = Pe^RT where A= amount, P= principal value, R = the rate, and t = time. E is an actual number that is kinda hard to explain but it's just a button on the calculator.

In this case the equation would be A = 350e^(0.03)(10). This gives you approximately 472.4506 or approximately $472.45 since it's money and you round to the nearest penny.

the answer is $472.45

On a adventure trail, you biked 12 mi, walked 4 mi, ran 6 mi, and swam 2 mi. What fraction of the total distance did you bike? Write this number as a decimal.

Answers

First you want to add all of those together.
12 + 4 + 6 + 2 = 24
So there are 24 miles in total.
Next, it says she biked 12 miles so you make a fraction.
12 / 24 which can be reduced to 1/2.
She spent one half of the total distance biking.
Hope this helps!

You biked 1/2, or 0.5, of the total distance on the adventure trail. The total distance covered was 24 miles.

To calculate the fraction of the total distance that you biked, we first need to determine the total distance covered in the adventure trail.

Biking: 12 milesWalking: 4 milesRunning: 6 milesSwimming: 2 miles

Adding these distances together gives us a total distance of:

Total Distance = 12 + 4 + 6 + 2 = 24 miles

The fraction of the distance biked is then given by the biking distance over the total distance:

Fraction Biked = 12 miles / 24 miles = 1/2

To express this fraction as a decimal, we perform the division:

Decimal Form = 1 ÷ 2 = 0.5

Therefore, you biked 1/2 (or 0.5) of the total distance.

A rabbit can run short distances at a rate of 35miles per hour.a fox can run short distances at a rate of 21 miles per half hour.which animal is faster,and by how much?

Answers

The fox is faster. This means that while the rabbit can run at a rate of 35 miles per hour, the fox runs 42 miles per hour. Therefore, the fox runs 7 more miles per hour than the rabbit.

Since the fox's rate is based on half an hour and the rabbit's rate is based on a whole hour, you would need to create an equation that is spanned on the same amount of time.

To do this you would, simply, multiply the fox's rate by 2.

21 x 2 = 42
[tex] \frac{1}{2} [/tex] x 2 = 1

42 mi/1 h

A fox can run 7 miles per hour faster than a rabbit can.

when writing an exponential function, how do you put 12.5% into a decimal.... for example 20% goes into .20 but how would I do that for 12.5? please help!

Answers

Remember that 1% is equivalent to 1 hundredth, or 0.01. What does 0.5% mean, then? Well, it's 0.5 hundredths, or five-tenths of a hundredth.

If we look at that in terms of fractions, that translates to:

[tex] \frac{5}{10}\times \frac{1}{100} = \frac{5}{1000}[/tex]

So, 0.5% is five thousandths, or 0.005, as a decimal. Combining that with 12%, which is 0.12 or twelve hundredths as a decimal, we have:

12.5% = 0.12 + 0.005 = 0.125

How many gallons of a plant food that is 9% nitrogen must be combined with another plant food that is 25% nitrogen to make 10 gal of a plant food that is 19% nitrogen?

Answers

Final answer:

To determine the amounts of two plant foods with different nitrogen percentages to create a desired mixture, we set up and solve a system of equations based on the total volume and total nitrogen content.

Explanation:

A mixture problem that involves combining two solutions with different percentages of nitrogen to achieve a solution with a desired percentage of nitrogen.

Let's denote the amount of the 9% nitrogen plant food as x gallons and the amount of the 25% nitrogen plant food as y gallons.

Given that we want to end up with 10 gallons of a 19% nitrogen mixture, we can form the following two equations based on the problem's requirements:

Equation 1: x + y = 10 (Total volume of the mixture)

Equation 2: 0.09x + 0.25y = 0.19 × 10 (Total amount of nitrogen in the mixture)

By solving this system simultaneously, we can find the values of x and y.

The second equation can also be written as 9x + 25y = 190 to work with whole numbers.

We can multiply the first equation by negative 9 and add it to the second equation to eliminate x and solve for y.

This will give us the amount of 25% nitrogen plant food needed, and by subtraction of y from 10, we can find the amount of 9% nitrogen plant food required.

Based on the results, we may need multiple gallons of the 9% nitrogen plant food and a specific number of gallons of the 25% nitrogen to achieve our desired 19% nitrogen plant food.

Final answer:

To find the number of gallons of a 9% nitrogen plant food to be combined with a 25% nitrogen plant food, we can set up an equation based on the principle of conservation of mass and solve for the variable representing the number of gallons of the 9% nitrogen plant food.

Explanation:

To find out how many gallons of a plant food that is 9% nitrogen must be combined with another plant food that is 25% nitrogen to make 10 gallons of a plant food that is 19% nitrogen, we can set up an equation based on the principle of conservation of mass.

Let x be the number of gallons of the 9% nitrogen plant food.

Then, (10 - x) would be the number of gallons of the 25% nitrogen plant food.

The equation can be set up as follows:

0.09x + 0.25(10 - x) = 0.19(10)

Solving the equation will give us the value of x, which represents the number of gallons of the 9% nitrogen plant food needed to be combined with the 25% nitrogen plant food.

on an average day, 34 customers buy a bag of grapes at jerry's market. there are an average of 47 grapes in each bag. round to the nearest ten and then multiply to estimate the number of grapes jerry's customers buy every day.

Answers

Answer:

Step-by-step explanation:

1,500

There are on an average 34 customers for Jerry everyday buy a bag of 47 grapes. Hence, around 1600 grapes he sell every day.

To estimate the number of grapes Jerry's customers buy every day, we can multiply the average number of bags sold by the average number of grapes per bag:

34 bags/day x 47 grapes/bag = 1598 grapes/day

Rounding 1598 to the nearest ten gives us:

1600 grapes/day

Therefore, we can estimate that Jerry's customers buy around 1600 grapes every day.
