Answer:  .65

Step-by-step explanation:

The decimal representation of the amount spent, which is ratio of amount spent and the total amount in wallet is 0.65

Amount spent = $13.00

Total amount in wallet = $20.00

Fraction spent = Amount spent / total amount

To express as a decimal;

Therefore, the fractional representation of the amount spent from total is 0.65.

a = [tex]\sqrt{\frac{4d}{bc} }[/tex]

isolate the term in a

[tex]\frac{1}{4}[/tex] a²bc = d ( multiply both sides by 4 to eliminate the fraction )

a²bc = 4d ( divide both sides by bc )

a² = [tex]\frac{4d}{bc}[/tex]

Take the square root of both sides

Gotcha!

Since there is no variables listed, I'll solve it both ways. :-)

f(-18)=2/3(-18)-4

Multiply the fraction by negative 18!

f=-12-4

answer: f=-16

If it's this way then it goes like this:

f(-18)=2/3-4(-18)

f=2/3+72

f=218/3 or f=72.66666..... Rounded: 72.7

Simplify [tex]\frac{12}{84}[/tex], 84 ÷ 12 = 7, so, [tex]\frac{12}{84}[/tex] as a unit fraction equals; [tex]\frac{1}{7}[/tex]

1/7

This is because 84 is divisible by 12 and  that would leave 7 in the denominator with 1 on top

the slope would be -2/3 hope this helps

answer:

y = 10 - x²

step-by-step explanation:

the y value is means the y value is equal to meaning the first part of our equation is y =

10 decreased means 10 minus so the next part of our equation is y = 10 -

the square of the x value means x squared so the last part of our equation is y = 10 - x²

The required expression is y =  10- x²

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given statement is ,

The y-value is ten decreased by the square of the x-value

So we have two variables x and y.

So square of x = x*x = x²

and, ten decreased by the square of the x-value = 10- x²

Hence we get y is 10- x²

So the expression is

y =  10- x²

Hence,the required expression is y = 10- x²

Answer:

Step-by-step explanation:

A side of a triangle is less than the sum of the lengths of the other two sides and is greater than the positive difference of them.

third side is in between 1.2 and 2.6 but it has to be a whole number so its 2

A possible measure of the third side is 2m (to the nearest whole number)

Using the triangular theorem which states that the measure of the third side of the triangle is less than the sum of the other two sides.

Given the length of the other two sides as 1.9m and 0.7m

Taking the sum

Since the length of the third side must e less than the sum, hence the required answer must be less than 2.6m.

Answer: 9 green peppers and 3 red peppers

Step-by-step explanation:

Lupe makes 12 servings:

She uses 12 green peppers and 4 red peppers.

If you want to know the number of each pepper that she needs for servings, you must divide the number of peppers by the number of servings:

green : 12/12 = 1

She needs one green pepper for serving:

red: 4/12 = 1/3

She needs one third of a red pepper for serving, so for 9 servings she needs:

9*1 = 9 green peppers

9*(1/3) = 9/3 = 3 red peppers

Answer:

m∠EFB = 157°

Step-by-step explanation:

We are given that m∠CFE = 90°

m∠AFB = 23° so;

m∠BFC = 90° - 23° = 67°

m∠EFB = m∠CFE + m∠BFC = 90° + 67° = 157°

Answer:

D. 157°

Step-by-step explanation:

Angle CFE is a right angle, as can be seen in the figure. So, m∠CFE = 90°. Two angles are congruent when they are equal. This means that angle CFE is equal to CFA, i. e., m∠CFA = 90°. Figure shown that m∠AFB + m∠BFC = m∠CFA. If m∠AFB = 23°, then, m∠BFC = 67°. It's also shown in the figure that m∠EFB = m∠CFE + m∠BFC. So, m∠EFB = 90° + 67° = 157°  

To find out the total length of the buttons when lined up, multiply the number of buttons by the length of one button (3/4 inch). An expression for this would be L = n  imes (3/4). A button is considered pressed if the extended key length K* is greater than or equal to LO, the rest length of the lock.

If Kara lines up all her 3/4 inch buttons, the total length of the buttons aligned in a row can be found by multiplying the number of buttons by the length of one button. Let's denote the number of buttons as n, and the length of one button as 3/4 inches. Hence, the expression for the total length L would be L = n  imes (3/4) inches. If the key K* finally stops at a position that is greater than or equal to the rest length of the lock LO, then the button will be pressed.

To determine whether the button will be pressed, we could set up an inequality: K* \\geq LO. If this condition holds true, Kara knows that the button is pressed.

16 is her weekly allowence

Imani's weekly allowance is $16. This is determined by setting up and solving an algebraic equation based on the information provided in the problem.

Let's use the information given in the problem. The student, Imani, had an initial allowance. She spent half of it on mini-golf and then earned an extra $4 by washing a car. After these transactions, she has $12 remaining. We can use this to set up a simple algebraic equation.

Let x be the initial allowance. We know from the problem that Imani spent half of it, which is 0.5x, on mini-golf and earned an extra $4. So, the equation can be written as:

0.5x + $4 = $12

Solving this equation gives the weekly allowance. If we subtract $4 from both sides of the equation, we get 0.5x = $8. If we then divide each side by 0.5, we find that x = $16.

So, Imani's weekly allowance is $16.

Answer:

A proportional relationship is a relation of the form:

Y = A*X

This means that if we have two variables, X and Y, for each unit that X grows, Y grows A times that.

And notice that the relation:

Y/A = X

is also a porportional relationship

This relationship can be expresed in a graph as a straight line that pases through the origin and has a constant unit of growht (in this case A) that is also called the "slope" of the line.

The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.

1) Graphing- If you graph the numbers you will easily be able to identify the answer.

2) Substitute- Substitute numbers in for x or y until they're equal on both sides.

EX: 2x+2=10

Substitute numbers in until you get a number that makes it equal on both sides

x= 4

3) Elimination- Eliminate numbers from both sides until they're equal.

27*12= 324 pounds of turkey

The ratio of girls to boys in the karate team remained the same at 2:3, both before and after the new members joined.

Initially, there were 6 girls and 9 boys, creating a ratio of 6 girls to 9 boys, which simplifies to 2:3 when divided by the greatest common divisor, 3. After 2 more girls and 3 more boys joined, the team had 8 girls and 12 boys.

This new ratio also simplifies to 2:3, since both the numerator and denominator can be divided by 4. Therefore, the ratio of girls to boys did not change after the new members joined the team; it remained the same at 2 girls for every 3 boys.

Remark

What exactly do you want? You have written the equation. So perhaps what you would like is the value for x.

When people start doing algebra usually they are asked what multiplied by 8 will give 40. There is no procedure to that, just an answer.

8 times 5 = 40. So the answer is 5.

You do know that 8x means 8*x or multiply 8 times x do you not?

Procedure

8*x = 40              Divide both sides by 8

8x ÷ 8 = 40÷8

x = 5

Answer:

y = (-2/5)x - 2

Step-by-step explanation:

One way to attack this problem is to interchange the coefficients of x and y and change the sign of one to +:  5x - 2y = -6 becomes 2x + 5y = c.  Solving for the slope, m, we get 5y = -2x + c first, and then y = (-2/5)x + D.

Subbing 5 for x and -4 for y, we now have -4 = (-2/5)(5) + D.

Then -4 = -2 + D, so that D = -2.

The desired equation is thus y = (-2/5)x - 2.

Check:  Does this pass through (5, -4)?  Is -4 = (-2/5)(5) - 2 true?  Yes.

Is the slope -2/5 the negative reciprocal of 5/2?  Yes, it is.

Add the ratios:

75 +1 = 76

Divide the total by that:

380 / 76 = 5

Multiply each ratio by 5:

75 * 5 = 375

1 * 5 = 5
