Answer:

4.5

Step-by-step explanation:

Answer:

1 / 180 + 1 / t = 1/84

t = 157.5 minutes

Step-by-step explanation:

3hrs = 180 minutes

1.4 hours = 84 minutes

your rate + friend's rate = rate together

1 lap in 180 min + 1 lap in t min = 1 lap in 84 min

The equation is

1 / 180 + 1 / t = 1/84

subtract 1/180 from both sides

1/t = 1/84 - 1/180

1/t = 0.006349206349

multiply both sides by t

1 = 0.006349206349t

Divide both sides by 0.006349206349

1 / 0.006349206349 = t

157.5 = t

t = 157.5 minutes

Answer: (5,1)

Step-by-step explanation:

Divide both sides of the equation by 3, Eliminate the x's and you should have 6y=6. After solving y to be 1 plug it into one of the equations to find x

Answer:

K12 Answer

Step-by-step explanation:

The solution of the linear equation 2.25 + n / 2 = −4 will be −12.5.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The sum of 2.25 and half a number is −4.

Let 'n' be the number. Then the equation is given as,

2.25 + n / 2 = −4

Simplify the equation, then we have

2.25 + n / 2 = −4

n / 2 = − 4 − 2.25

n / 2 = −6.25

n = −12.5

The solution of the linear equation 2.25 + n / 2 = −4 will be −12.5.

Answer:

2

Step-by-step explanation:

We know 10 1/2 is basically 10.5 or 21/2

To find the max amount of scarves she can make, simply divide the number of yards she has by 4. This will get you the number of scarves she can create.

[tex]\frac{21/2}{4} = \frac{21}{2} * \frac{1}{4} = 21/8 = 2.625[/tex]

Well.. we don't want to make .625 of a scarf since that would be ridiculous, so we will round it down to 2 since we can't make 3 either.

The max amount of scarves she can make is 2.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 4x (7x - 11)

Now,

Solve the expression as;

⇒ 4x (7x - 11)

⇒ 4x × 7x - 4x × 11

⇒ 28x² - 44x

Thus, The expand form will be;

Answer:

approximately 1.13

Step-by-step explanation:

[tex](f \circ f) = f(f(3))[/tex]

Working from the inside...

[tex]f(3) = 3^{-3} =\frac{1}{3^3} = \frac{1}{27}[/tex]

Now put this result back into  f  again.

[tex]f(\frac{1}{27})=\left(\frac{1}{27}\right)^\frac{1}{27}[/tex]

Use a calculator to approximate this; the result is 1.13.

Note:  an "exact" answer is [tex]\frac{1}{\sqrt[27]{\frac{1}{27}}}[/tex].

Correct choice is A

When raising one power to another power multiply the two powers together:

(3y^3)^2 = 3y^(3 * 2) = 3y^6

Answer: 3y^6

The expression [tex](3y^3)^2[/tex] is simplified by applying the exponent rules and the value is [tex]9y^6[/tex]

Given data:

The expression [tex](3y^3)^2[/tex]  can be simplified by applying the exponent rules. To remove the exponents, we multiply the base and raise it to the power of the product of the outer and inner exponents. In this case, the base is [tex]3y^3[/tex], and the exponent is 2.

First, square the numerical coefficient, which is 3, to get [tex]3^2 = 9[/tex]. Next, apply the exponent to the variable term [tex]y^3[/tex] by multiplying the outer exponent (2) with the inner exponent (3), resulting in  [tex]y^(3 * 2) = y^6[/tex].

Hence, [tex](3y^3)^2[/tex]  simplifies to [tex]9y^6[/tex] . This means that the expression represents the result of squaring the quantity [tex]3y^3[/tex], resulting in 9 times the sixth power of y. It's essential to understand and apply exponent rules to efficiently simplify expressions and evaluate mathematical operations without using exponents directly.

Answer:

im going to be honest i havent done this since las year and so i dont remember the value of that line outside but i think its 70*

Step-by-step explanation:

reason is because the c is originally 180* but it has more of and angle so the angles obv increases and you can get the angle by multiplying 70*times 7x and divide by 3

i say 3 because of the amount of angles in a triangle and the line outside if i remember correctly is the "angles" of a triangle  and that would be your answer

Answer:

x=36

Step-by-step explanation:

These angles added together equal 180 degrees

2x + 3x =180

5x = 180

x = 36

Answer:

x  = 36    

Step-by-step explanation:

2x and 3x are supplementary angles they both add up to 180 degree Therefore 2x + 3x = 180   5x = 180   180/5 = x      x  = 36

Step-by-step explanation:

The distance from where Olivia started to the finish line is 600 foot

A model function is a way of describing a real-life system or situation using mathematical concepts and language

If Olivia rode at a speed of 20 feet per second, while William rode at a speed of 15 feet per second. Olivia gave William a 150-foot head start.

We can write write a linear model function for both Olivia and William as follows:

Olivia: y = 20x

William: y = 15x + 150

where y is the distance and x is the time taken to reach finish line

Since the race ended in a tie (i.e. draw), we can equate the two functions:

20x = 15x + 150

20x -15x = 150

5x = 150

x = 150/5

x = 30 seconds

Thus, the distance from the finish line to where Olivia started can be determined by substituting x = 30 into y = 20x. That is:

y = 20(30) = 600 foot

B) 5.555 inches

Step-by-step explanation:

Each tile has its own constant width of 2 3/4 in. and length of 5 1/2 in.

The width of the sidewalk is 9 tiles wide; therefore, the width in inches can be found by calculating 9 x 2 3/4

The length of the sidewalk is 25 tiles long; therefore, the width in inches can be found by calculating 25 x 5 1/2

Sidewalk:  W = 24 3/4 in.  L = 137 1/2 in.

A) L-W

B) L/W

Answer: 8

Step-by-step explanation:

A really simple way to solve these problems is to think of g(whatever number) as the y coordinate on your graph. Therefore the question is basically asking you if x is 10, what is y. If we find 10 on the x axis, we can count up the y axis until we reach the line. So, the answer is 8

Yes you found it correct as per slope intercect form y=mx+b

Here

Slope=m=1/2

Y intercect=5

Now.

for g(10)

The coordinate is (10,8)

So

g(10)=8
