The ratio of students with brown eyes in Michelle’s class to all of the students in her class is 20:25. What is another way to write this ratio?

Answer:

By making x = -3

Step-by-step explanation:

If X was -3 then -3 plus 3 equals 0, and 2 multiplied by 0 is 0, so the problem will have no solution.

Step-by-step explanation:

-3t-4t+20=48

-7t=28

t=-4

Answer:

t = -4

Step-by-step explanation:

-3t – 4 (t – 5) = 48

Distribute

-3t -4t +20 = 48

Combine like terms

-7t +20 = 48

Subtract 20 from each side

-7t +20-20 = 48-20

-7t = 28

Divide by -7

-7t/-7 = 28/-7

t = -4

Answer:

35 feets

Step-by-step explanation:

Initial Position = - 25 feets

Final height reached after jumping = 10 feets

The vertical distance traveled by dolphin :

Final height reached - Initial position

(10 feets) - (-25 feets)

10 feets + 25 feets

= 35 feets

Answer:the answer is 33

Step-by-step explanation:

The balance on the credit card will be $33.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Braden's credit card balance was $162. He charged $54 then makes a $75 payment the balance amount will be calculated as below:-

Balance = 162 - 75 - 54

Balance = 162 - 129

Balance = $33

Therefore, the balance on the credit card will be $33.

y=4x-1

Step-by-step explanation:

We know that the slope equation is y=mx+b. M is the slope and B is the y-intercept. M is provided to be 4 and B is provided to be -1, so all we have to do is plug them in to get the answer.

Answer:

y = 4x - 1

Step-by-step explanation:

Slope-intercept form:

y = mx + b

So, input all the values...

y = 4x - 1

Answer:

The function would be linear because the rate of change is constant.

Step-by-step explanation:

Given

[tex]Base= \$89.00[/tex]

[tex]Rate = \$0.10[/tex] per minute

See attachment for complete question and options

First, we write the function that calculates the cost (C(t)) for t minutes.

This is calculated as:

[tex]Cost = Base + Rate * t[/tex]

[tex]C(t) = 89.00 + 0.10 * t[/tex]

[tex]C(t) = 89.00 + 0.10t[/tex]

Rewrite as:

[tex]C(t) = 0.10t + 89.00[/tex]

A function that has the above format is referred to as a linear function which has the general format

[tex]f(x) = mx + b[/tex]

Where

m represents the slope/rate and it is constant

From the list of given options, (a) is correct.

Step-by-step explanation:

since this is a special right triangle (45, 45, 90) we can use right triangle rules. Basically, C in my photo is equal to the hypotenuse while A and B are equal to the sides. You can substitute your hypotenuse into the formula I gave you to find x.

B = C / root2

x = root3 / root2

Answer:

a).cruz is right.

b).-64 is cube root of -4.

c).because -64 is square root of -8.

Step-by-step explanation:

1.Cruz is right

2. If the nth root of the negative number is a odd number, the answer is negative this of the FOLLOWING is the example not the answer

[tex] \sqrt[5]{ - 243} = [/tex]

[tex]( - 3 \times - 3) = 9[/tex]

[tex]9 \times ( - 3) = - 27[/tex]

[tex] - 27 \times - 3 = 81[/tex]

[tex]81 \times - 3 = - 24 3[/tex]

So the answer is -3

For -64

[tex] - 4 \times - 4 = 16[/tex]

[tex]16 \times - 4 = 64[/tex]

So Cruz is right.

3. Aaron is wrong because it asked for the 3rd root of -64 and -8 isn't that.

Jacob is wrong because the nth root is a odd number and the number under the radical s negative so it going to give us a negative number(which is a real number)

Answer:

Area=[tex]\frac{13(6)}{2}[/tex]

        =[tex]\frac{78}{2}[/tex]

       =39

Step-by-step explanation:

Answer:

39 ft

Step-by-step explanation:

use the formula for the area of the triangle (base*height)/2

(13*6)/2=78/2= 39 ft

Answer-A

Step-by-step explanation:

Reason- in order to have two lines be parallel they must have the same slope, in this case the slope has to be 3x. If you look at A it is 2y=6x+8 and to graph it, y has to be by itself. so you divide both sides by two making it y=3x+4, and as you can see it now has a slope of 3x.

p = 2 or p = -2

Step-by-step explanation:

Solve for p over the real numbers:

16 p^2 - 64 = 0

Hint: | Factor constant terms from the left hand side.

16 p^2 - 64 = 16 (p^2 - 4):

16 (p^2 - 4) = 0

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by 16:

p^2 - 4 = 0

Hint: | Using the quadratic formula, solve for p.

p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:

Answer:

She shouldn't tip at all since that's a ridiculous concept

Step-by-step explanation:

common sense

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP

The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so

cost = price + 0.1*price

cost = 1.1 * price

price = cost / 1.1

price = 22 / 1.1 = 20

now we need 20% of that so that's

20 * 0.2 = 4

If she's simple-minded enough to tip that would amount to $4

Answer:

they are parallels

Step-by-step explanation:

they have the same slope but different y intercepts so they are parallel

Answer:

Parallel

Step-by-step explanation:

First, you should put the second equation in slope-intercept form, it would be y=3x+8.

If two lines are parallel they will have the same slope. If two lines are perpendicular the slopes will be the negative reciprocals of each other. The slopes of these two lines are the same so they are parallel.

Answer:

d = 2

Step-by-step explanation:

14d - 22 +5d = 12d - 8

19d -22 = 12d - 8

      +22         +22

    19d = 12d + 14

  -12d   -12d

     7d = 14

    /7       /7

      d = 2

Answer:

d = 2

Step-by-step explanation:

Simplifying

14d + -22 + 5d = 12d + -8

Reorder the terms:

-22 + 14d + 5d = 12d + -8

Combine like terms: 14d + 5d = 19d

-22 + 19d = 12d + -8

Reorder the terms:

-22 + 19d = -8 + 12d

Solving

-22 + 19d = -8 + 12d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-12d' to each side of the equation.

-22 + 19d + -12d = -8 + 12d + -12d

Combine like terms: 19d + -12d = 7d

-22 + 7d = -8 + 12d + -12d

Combine like terms: 12d + -12d = 0

-22 + 7d = -8 + 0

-22 + 7d = -8

Add '22' to each side of the equation.

-22 + 22 + 7d = -8 + 22

Combine like terms: -22 + 22 = 0

0 + 7d = -8 + 22

7d = -8 + 22

Combine like terms: -8 + 22 = 14

7d = 14

Divide each side by '7'.

d = 2

Simplifying

d = 2

Answer:

24 is the answer

Step-by-step explanation:

* 29-5=24

* 24+5=29

Answer:

23/5

is the 4.6 fraction

The decimal 4.6 is equivalent to the fraction 23/5.

The whole number part of the decimal, which is 4, will be the numerator of the fraction.

The decimal part, which is 0.6, will be the numerator of the fraction divided by the appropriate power of 10.

In this case, the decimal has one digit after the decimal point, so we divide it by 10¹.

0.6 / (10¹)

= 0.6 / 10 = 6/10

Simplify the fraction if possible.

Both the numerator and denominator can be divided by their greatest common divisor, which is 2 in this case.

6/10 = (6/2) / (10/2) = 3/5

Therefore, the decimal 4.6 is equivalent to the fraction 4 3/5 or simply 23/5 after simplification.
