Answer: Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.

Step-by-step explanation: So for the top part your answer is supposed to be 4400.2 grams of protein in 7 weeks. You can get that by adding up the grams of protein for each type of food on the chart. Then you multiply that by 2 to get the amount they will be eating for 1 day which is 89.8. After that, because you have to solve for how much they will be eating for 7 weeks, you will have to multiply 89.9 x 49(days in total). To get you to the answer 4400.2. Now you have your answer for the second part of the problem. Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.

Step-by-step explanation:

The rate of the block of glasses is, $18.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Kim pays $90 for every block of 5 dance classes.

Here, Kim pays $90 for every block of 5 dance classes.

Hence, The rate of the block of glasses is,

⇒ $90 / 5

Answer:

$199.75

Step-by-step explanation:

Total money she has be x,

→ x = 1200.45 + 85

→ [ x = $1285.45 ]

Katelyn totally spend be y,

→ y = 85.70 + 1000

→ [ y = $1085.70 ]

Money left in Katelyn's account at the end of the month,

→ x - y

→ 1285.45 - 1085.70

→ $199.75

Hence, the money left is $199.75.

In order to find the mean of the sandwich shop you would add all of them up so 73+88+85+88+99+134+129 = 696. Then you divide it by how many days there are which there are 7 days so 696÷7=99.43. To find the median order the number least to greatest, then u count how many numbers are in the set. Count inwards and the median would be 88. The mode is the set of number that is in the problem the most, so in this case the mode would be 88. In order to find the range you subtract the highest number from the lowest number, so 134-73. The range would be 61. The measure that would be most helpful is the median, because it is not affected by the outliers!!

The mixed number for the  given case can be obtained as 10²/₅.

A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.

Suppose the number be x.

Then, the following equation can be written for information given as,

1/4(x - 3.2) = 1.8

It can be solved as,

x - 3.2 = 1.8 × 4

⇒ x = 7.2 + 3.2 = 10.4

It can be written in mixed form as below,

10.4 = 10 + 4/10

⇒ 10 + 2/5 = 10²/₅

Hence, the required number is 10²/₅.

when you're doing a perpendicular line, you want the exact opposite of your original.

take, for example, a line with a slope of 2. the line perpendicular to it would have a slope of -2.

With a fraction, its pretty tricky. Let's say you have 2/7 as your slope. you want the EXACT opposite so

First, make it negative

Next, flip it around.

You get -7/2 as your slope perpendicular to your original line.

For the point passing through, if x equals 0, y equals your y intercept. your y value is 3 therefore b (y-intercept) equals 3.

For questions that are less simple than a plain y-intercept, (which you are guaranteed to encounter in the future) you simply input the y and x values into your y=mx+b equation.

Say we have an example here of a line with a slope of 4, and it passes through (5,-3). We have to find our B, or y-intercept, so we input the values.

-3=4(5)+b

Now, simplify

-3=20+b

-23=b

Your example equation is now y=4x-23

Then, i did 0 x 2 and 2 x 0 to get 0, then i added and moved the decimal from 2.2 one time to make it 15.4. To check my work, i did 15.4 divided by 7 to get 2.2.

Answer:

I believe that the answer is -1/2

Step-by-step explanation:

The number which falls under the inequality -3/4 < x < 5/8 is when x = -1/2

The correct answer is Option D.

Given data:

The number x is between -3/4 and 5/8.

So, the inequality is -3/4 < x < 5/8.

When comparing fractions, we consider their relative positions based on their magnitudes. Starting from the left, -3/4 represents a point closer to negative infinity, followed by -1/2, and then 5/8, which is closer to positive infinity.

Visually, imagine the number line where -3/4 is to the left, 5/8 is to the right, and -1/2 is positioned between them. Since -1/2 is greater than -3/4 and less than 5/8, it falls within the specified range. The choice -1/2 satisfies the condition and can be identified as the number between -3/4 and 5/8.

Hence, the number is x = -1/2.
