Answer:

3.5 miles per hour of speed

Step-by-step explanation:

Given:

To find:

0.875                      15

             x                           60

Answer: Lien walked 3.5 miles per hour of speed.

Step-by-step explanation:

Distance Lien walked = 7/8 of a mile = 0.875 miles

Time of walking = 1/4 of an hour = 15 minutes

Distance in miles     Time in minutes

          0.875                      15

             x                           60

Calculations:

15x = 0.875 * 60

15x = 52.5

x = 52.5/15

x = 3.5

The  expression without absolute value |120+x| if x<-120 is -120 - x

Given the absolute value expression |120 + x|

If x < -120, the resulting expression will be;

|120 + x| = -(120 + x)
|120 + x| = -120 - x

Hence the  expression without absolute value |120+x| if x<-120 is -120 - x

I don't really understand your question as in how many solutions.

Well if its to combine like terms the solution is below.

Answer:

D. y=x+5

Step-by-step explanation:

Find the slope of the line. Remember to use equation: m=y2−y1/x2−x1

m= 5-(2)/0-(-3)

Simplify both numerator and denominator, then divide. You'll get m=1

Use the slope 1 and a given point (−3,2) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1).

y−(2)=1⋅(x−(−3))

Simplify the equation.

y−2=1⋅(x+3)

Solve for y by multiplying x+3 by 1.

y−2=x+3

Move everything that doesnt contain y to the right by adding 2 to both sides of the equation

y=x+3+2

and then added 3 and 2.

y=x+5

Step-by-step explanation:

the line is

20x - 17y = 15

I am not sure what your teacher uses as "standard form".

the works is split between "point-slope" and "slope-intercept" form as "standard".

I usually pick "slope-intercept" :

y = ax + b

with a being the slope and b being the y-intercept.

in any case, we can find the x-intercept without bringing the line equation to one of these forms.

because x-intercept simply means that y = 0.

and for y=0 the original equation is then

20x - 17×0 = 15

20x = 15

x = 15/20 = 3/4

Answer:

you multiply 300 by 5 % and that gives you 15

Answer:

[tex]x=7, x=-3[/tex]

Step-by-step explanation:

Bring the 21 on the LHS:

[tex]x^2-4x-21=0[/tex]

At this point we need to find two numbers whose product is -21, and whose sum is -4.

From the product we can tell that one has to be positive, and one is negative.

From the sum, we can tell that the greater of the two is negative.

At this point we look at the factors of 21: 1,3,7,21.

In particular, 3 and -7 added togheter do -4, which is what we need. At this point we can factor the trinomial as

[tex](x-7)(x+3)=0[/tex]

Considering that a product is zero if any of the factors is zero, it's:[tex]x-7=0 \rightarrow x=7\\x+3=0 \rightarrow x=-3[/tex]

Answer:

555.7 in²

Step-by-step explanation:

Lateral surface area of a cylinder is the "side" surface area only.  Lateral SA does not include the surface area of the 2 circular ends.

[tex]\textsf{lateral SA}=2\pi rh[/tex]

(where r is the radius and h is the height)

Given:

Substituting these values into the formula:

[tex]\implies \textsf{lateral SA}=2\pi \cdot 4.4 \cdot 20.1[/tex]

[tex]\implies \textsf{lateral SA}=555.7 \textsf{ in}^2 \textsf{ (nearest tenth)}[/tex]

Answer:

1$

Step-by-step explanation:

Her total amount is 40$

She then buys the tires(tires = 21$) so she bought that subtract 21$ from 40$ 40$ - 21$=19$

She next wanted to buy a bell so she did the bell was 5$ so subtract 5$ from 19$ 19$-5$=14$ left

So remember she has 14$ left and she is buying a basket which is 13$ so her buying the basket is remaining her with 1$ because basket is 13$ and she has 14$ so what is 14$-13$ it is 1$  and there's your answer.

Answer:

6(y - 3)(2y + 5)

Step-by-step explanation:

12y^2 - 6y - 90

Factorize

6(2y^2 - y - 15)

Split the term

6(2y^2 - 6y + 5y - 15)

Regroup terms

6((2y^2 - 6y) + (5y - 15))

Factorize

6((2y(y - 3) + 5( y - 3))

Factorize

6(y - 3)(2y + 5)

Answer:

[tex]6(y-3)(2y+5)[/tex]

Step-by-step explanation:

[tex]12y^2-6y-90[/tex]

First, factor out the common term of 6:

[tex]\implies 6(2y^2-y-15)[/tex]

To factor [tex](2y^2-y-15)[/tex]:

Multiply the coefficient of [tex]y^2[/tex] by the constant:

[tex]\implies 2 \times -15 = -30[/tex]

Now find factors of -30 that sum to the coefficient of [tex]-y[/tex], i.e. -1

Factors of 30:  1, 2, 3, 5, 6, 10, 15, 30

So factors of -30 that sum of -1 are:  -6 and 5

Rewrite the middle term of [tex](2y^2-y-15)[/tex] as [tex]-6y + 5y[/tex]:

[tex]\implies 2y^2-6y+5y-15[/tex]

Factor each pair of terms:

[tex]\implies 2y(y-3)+5(y-3)[/tex]

Factor out the constant term:

[tex]\implies (y-3)(2y+5)[/tex]

Therefore, the final factorization is:

[tex]\implies 6(y-3)(2y+5)[/tex]

Answer:

15g

Step-by-step explanation:

Method A: Calculate the percent first

If you decrease an amount by 25%, you end up with 75% of the amount.

75% of 20g = 0.75 × 20g = 15g

Method B: Calculate the decrease first

We start with 20g. To decrease 20g by 25%, we calculate 25% of 20g.

25% of 20g = 0.25 × 20g = 5g

The decrease amount is 5g.

Now we subtract 5g from 20g.

20g - 5g = 15g

The larger of the triangle’s two acute angles is 65 degrees

Given the expression

sin(x+4) = cos(3x + 2)

Since sin theta = cos(90 - theta), hence;

cos(90 - (x+4)) = cos(3x +2)

cos(86 - x) = cos (3x+2)

Cancel out the cosine functions to have:

86 - x = 3x + 2

-4x = -84

x = 21

Substitute x = 21 into the expression

sin(x+4) = Sin25 =

Hence the larger of the triangle’s two acute angles is 65 degrees

Answer: 11 gems

Step-by-step explanation:

After Aaron gives 12 gems to his sister, he is left with 100-12 gems = 88 gems.

If he divides the gems evenly among the crowns, each one will have 88/8 gems = 11 gems.

Answer:You would wind up with (3, 2). When we move the point to the left, we subtract the amount that we move. 5 - 2 = 3And when we move down, we also subtract by that number in the y portion. 4 - 2 = 2(3, 2)

Step-by-step explanation:

Suppose adult tickets are x ticket

Student tickets are 1216 - x ticket

x(5) + (1216 - x)(1) = 2596

5x + 1216 - x = 2596

4x = 2596 - 1216

4x = 1380

x = 345

Adult tickets have 345 tickets

and student tickets have 1216 - 345 = 871 tickets.

Remaining payment left     = 5390-2300 = $3090

APR = 16.5% or 0.165

Time (t) = 14 months = 14/12 years

Using credit card payment calculator,

Monthly payment = $244.15

Hence, minimum monthly payment to be made to pay off the whole debt in 14 months = $244.15

Answer:

Step-by-step explanation:

We are told to model the number of students in the club. That is the dependent variable, so we will assign 'y' to that quantity. The number of students in the club is a function of the number of weeks since it was formed, so we can assign 'x' to that independent variable.

The initial value of y is 6, and it increases by 3x (that is, 3 students each week). The model of the number of homework club students can be ...

  y = 3x +6
