Answer:

2.33 ounces

Step-by-step explanation:

Given that:

Ounces of granola used = 34.95 ounces

Number of servings of trail mix = 15 servings

Since each serving contains the same amount of granola :

Amount of granola in each serving :

Ounces of granola used / Number of servings

34.95 / 15

= 2.33 ounces of granola per serving

Answer:

[tex]\sqrt{x^2+y^2+1}=18[/tex]

Step-by-step explanation:

We are given:

[tex]x^2=18x+y\qquad\qquad[1][/tex]

[tex]y^2=18y+x\qquad\qquad[2][/tex]

Subtracting [1] and [2]:

[tex]x^2-y^2=18x+y-(18y+x)[/tex]

Operating:

[tex]x^2-y^2=18x+y-18y-x[/tex]

Recall:

[tex]x^2-y^2=(x-y)(x+y)[/tex]

Substituting:

[tex](x-y)(x+y)=18x+y-18y-x[/tex]

Rearranging:

[tex](x-y)(x+y)=18x-18y-(x-y)[/tex]

[tex](x-y)(x+y)=18(x-y)-(x-y)[/tex]

Dividing by x-y (recall x≠y):

[tex]x+y=18-1=17[/tex]

[tex]x+y=17\qquad[3][/tex]

Now we add [1] and [2]:

[tex]x^2+y^2=18x+y+18y+x[/tex]

Rearranging:

[tex]x^2+y^2=18x+18y+x+y[/tex]

[tex]x^2+y^2=18(x+y)+(x+y)[/tex]

[tex]x^2+y^2=19(x+y)[/tex]

Substituting from [3]

[tex]x^2+y^2=19*17=323[/tex]

Adding 1:

[tex]x^2+y^2+1=324[/tex]

Taking the square root:

[tex]\sqrt{x^2+y^2+1}=\sqrt{324}=18[/tex]

Thus:

[tex]\mathbf{\sqrt{x^2+y^2+1}=18}[/tex]

Answer:

y=2/3x-5

Step-by-step explanation:

First, let's put this equation into slope-intercept form.

2x-3y=24

-3y=-2x+24

y=2/3x-8

For two lines to be parallel, they must have the same slope. Therefore our slope is 2/3.

Now, we must find b. To do that we can plug the y and the x in.

-7=2/3(-3)+b

-7=-2+b

-5=b

y=2/3x-5

Answer:

y = [tex]\frac{2}{3}[/tex]x - 5

Step-by-step explanation:

Points: (-3, -7)

Equation: 2x - 3y = 24

2x - 3y = 24

-3y = -2x + 24

y = [tex]\frac{2}{3}[/tex]x - 8

y = [tex]\frac{2}{3}[/tex]x + b

-7 = [tex]\frac{2}{3}[/tex] ( -3 ) + b

-7 = -2 + b

b = -5

y = [tex]\frac{2}{3}[/tex]x - 5

Answer:

A - 90ml

B - 150ml

Step-by-step explanation:

A - 150ml ÷ 100 = 1.5 x 60 = 90ml

B - 250ml ÷ 100 = 2.5 x 60 = 150ml

Brandon needs 90 ml and 150 ml of alcohol to make 150 ml and 250 ml hand sanitizer.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Brandon decided to make his own hand sanitizer.

To be effective, hand sanitizer should contain 60% alcohol.

a) 150ml of hand sanitizer;

Use percentage formula,

Percentage of alcohol = 150 x 60 / 100

Percentage of alcohol = 90 ml

a) 250ml of hand sanitizer;

Use percentage formula,

Percentage of alcohol = 250 x 60 / 100

Percentage of alcohol = 150 ml

Therefore, he needs 90 ml and 150 ml of alcohol to make 150 ml and 250 ml hand sanitizer.

Step-by-step explanation:

1.) As the sun light travels along path through as atmosphere to reach our eyes, the blue light has been mostly remove living mostly red and yellow light remain since red light waves are scattered the list by atmospheric gas molecules

2.) Rainbows are formed when it’s misty or spray the sky with water. It’s not solely just from after a rain; you only need water that can act at as prism and light to shine to create a rainbow.

3.) Having gold at the end of rainbow is just a myth since you can never reach the end of the rainbow. A rainbow is caused by dispersion of light in water droplet which is why they occur when sun comes out after rain.

Answer:

What 108 represents here is that the total number of phones she has to fix each week is 108 phones

Step-by-step explanation:

The linear equation is

P = 108-23d

compare this with the general form;

y = mx + c

we have;

P = -23d + 108

We can see that 108 represents the y-intercept in this case

The x-value at the y-intercept is 0

So what this mean is that the number of phones she has to fix each week is 108

Answer:

A is the correct equation to use when solving this problem

The least number of cars she can wash is 15

Step-by-step explanation:

If "'x" is the number of cars Emilia washes, then we would need to multiply that by the amount of money she gets from each car which means that "14x" needs to be in the equation somewhere. From this, we can already rule out C and D because those don't have "14x".

Also, since it says that Emilia needs at least $240, that would mean that she needs $240 or higher. Since the sign in equation A shows that, we know that it is equation A.

Since Emilia needs $240 or higher, the least number of cars she could wash would need to give her enough money to get to $240 when added to the $30 Emilia already has. We can multiply 14 by 15 to give us 210 which when added to the $30 she already has, will give us $240 which is the minimum amount of money she needs to buy new headphones.

Answer:

95.40 total and 5.40 in intreset

Step-by-step explanation:

Answer:

A = $95.40

I = A - P = $5.40

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

A = 90(1 + (0.06 × 1)) = 95.4

A = $95.40

The total amount accrued, principal plus interest, from simple interest on a principal of $90.00 at a rate of 6% per year for 1 years is $95.40.

Answer:

In each bowl, Cory put 500 grams of candy.

Step-by-step explanation:

You would do 4,500 - 1 (since he save a kilogram for himself), which would equal 3,500.

Then, you would do 3,500 divided by 7 (since there are 7 bowls and he wants to split the remaining candy evenly), which would equal 500.

Answer:

Cory served 500 grams of candy in each bowl.

Step-by-step explanation:

4,500 = 4.50 kilograms

4.50kg - 1.00kg = 3.50kg

3.50kg ÷ 7kg = 0.50kg

0.50kg = 500g

Answer:

Area: 196

Perimeter: 56

Step-by-step explanation:

1. Pick a side for both length and height and count the distance between the two coordinates (for example VU and UT)

VU = 14

UT= 14

Also important to note here that you don't even need to count the distance for both because since it's a square, all the sides are the same. Only did this to make it easier to understand the next step.

2. Since it's a square, as I said before, all sides are the same. So, you can go ahead and mark WT and VW as 14 as well.

3. To get the area, use the formula base times height.

14 x 14 = 196

4. For perimeter, simply add up all the sides (or multiply 14 by 4 since all are the same)

14+14+14+14=56

Answer:

-1/626 and for 23-3x=2   x=7

Step-by-step explanation:

Answer:

the answer is 612 -4n4+6n-5772

The expression that has like terms is (C) 7n+4n-3m-6n.

An expression can be as simple as a single number or variable, or it can be more complex, involving multiple operations and variables.

For example, the expression "3x + 4" contains the variable x, along with the constant values 3 and 4, and the operations of multiplication and addition.

Like terms are terms that have the same variables raised to the same powers.

In the first expression, 9n^7 and -2n have different powers of n, so they are not like terms. The constant term, -4112, is also not like any other term.

In the second expression, 3n and -3 are like terms, as they are both constants with no variables.

In the third expression, 7n, 4n, and -6n are all like terms because they all have the same variable, n, raised to the first power.

In the fourth expression, -4n^4 and 6n have different powers of n, so they are not like terms. The constant term, 612-5772=-5160, is also not like any other term.

Therefore, the expression that has like terms is (C) 7n+4n-3m-6n.
