Answer:

7/20

Step-by-step explanation:

first we want to write 35% like [tex]\frac{35}{100}[/tex] and divide both the numerator and the denominator by 5 and when we do that we get [tex]\frac{7}{20}[/tex]

Answer:

y= 3/4x +3

Step-by-step explanation:

Use point-slope form: y+3= 3/4(x+8)

Simplify: y+3= 3/4x+6

Simplify more: y= 3/4x+3

Hope this helped!

Answer:

y = - x - 11

Step-by-step explanation:

General slope intercept formula is y = mx + c

Hence you just need to rearrange this equation (put x on the other side)

Answer:

[3+ 1- (2 )]³

Step-by-step explanation:

[3+ 1- (2 )]³= 8

[ 4-2]³=8

[2]³= 8

The smaller brackets around 2 indicate that minus is being multiplied by 2 making it -2. As the signs of 1and 3 are the same i.e + they both are added and the answer is 4. Now 4 has the +ve  sign and 2 has the -ve sign so 2 is subtracted from 4 and we get a +ve 2 . Now 2 raise to power 3 gives 8 which is the required number.

Only 2 raised to power 3 gives a 8. any other number like 3 or 1 raise to power does not give an eight.

Answer: The person bike 20 miles in an hour.

Step-by-step explanation:

Given: At a constant speed, a person travels [tex]2\dfrac12[/tex] miles in [tex]\dfrac18[/tex] hour.

As [tex]2\dfrac12=\dfrac{2\times2+1}{2}=\dfrac{5}{2}[/tex]

So, in [tex]\dfrac18[/tex] hour, distance traveled = [tex]\dfrac52[/tex] miles

As time and distance are proportional, Multiply 8 om both sides , we get  

In 1 hour, distance traveled = [tex]\dfrac52\times8[/tex] miles

[tex]=5\times4[/tex] miles= 20 miles

Hence, the person bike 20 miles in an hour.

Answer: 20.1

Step-by-step explanation: Based on triangle sum theorem all angles add up to 180. 3x-11+6x-10+x=180

Combine like terms. 10x-21=180

Add 21 to both sides. 10x=201

Divide by 10 on both sides. X=20.1

Answer:

y = 1/7x + 23/7 or y = 1/7x + 3 and 2/7

Step-by-step explanation:

If you are learning about this, I suppose you know the formula or how to get the slope. You want to divide the rise over run or take the two y values divided the two x values:

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

The two points we have are (-2, 3) and (5, 4)

So:

4 - 3 / 5 - (-2)

1 / 5 + 2

Slope: 1 / 7

Now we want to find b in y = mx + b,

We can write it as y = 1/6x + b, then plug in a y and x value:

3 = 1/7(-2) + b

3 + 2/7 = b

b = 23/7

We can check by using the other point we have:

4 = 1/7(5) + b

4 - 5/7 = b

b = 23/7 or 3 and 2/7

Then the equation is: y = 1/7x + 23/7

Answer:

The number of years is  15 years

Step-by-step explanation:

From the question we are told that

     The present value is  [tex]PV = - \$ 12,241.93[/tex]

     The year payment required to reach future goal is [tex]PMT = - \$5,000[/tex]

      The future goal is  [tex]FV = \$210,000[/tex]

      The interest per year is [tex]r = 10\% = 0.10[/tex]

The negative sign shows that the fund are not gain made but they are being deducted

Follows are the solution to this question:

Step-by-step explanation:

The general term for temperature variations from 8 am to 10 am:  

[tex]\to \delta_{S - 10}=\delta_{S -9}+\delta_{S-10}[/tex] Where [tex]\delta[/tex] represents a transition throughout the time interval subscribed to.  

In this, the city of A:  

[tex]\to \delta_{S-10}=4-7= -3^{\circ}\ F[/tex]

In this, the city of B:  

[tex]\to \delta_{S-10}=-6-2= -8^{\circ}\ F[/tex]

It decrease of 3°  (non-value) overall in city A.  

Temporarily, in city B, is 8° C. City B has a greater temperature change (8 vs. 3) between A and B.

D. 10x^2+4x+3

Step-by-step explanation:

You get this by adding all the terms!

Answer: D. 10x^2 + 4x + 3

To find the combined area, add both of the areas together.

A = (3x^2 - x + 7) + (7x^2 + 5x - 4) (Remove the parentheses)

A = 3x^2 - x + 7 + 7x^2 + 5x - 4 (Combine the like terms)

A = 10x^2 + 4x + 3

∴ the combined area of Tiffany's fence and lawn is 10x^2 + 4x + 3.

Answer:

Length = 25cm

Width = 12.5 cm

Perimeter = 75cm

Step-by-step explanation:

Given that:

Actual measurement of rectangular swimming pool:

Length = 60 m

Width = 30 m

Scale = 5cm : 12 m

dimension of scale drawing

Length = 5/12 * 60 = 25cm

Width = 5/12 * 30 = 12.5cm

Perimeter of Scale drawing :

2(length + Width)

2(25cm + 12.5cm)

2(37.5cm)

= 75cm

Answer:

y=4x-10

Step-by-step explanation:

Answer:

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Step-by-step explanation:

Answer:

First convert numbers into prime numbers. find which number(s) is/are repeating. Multiply all numbers execpt for the number that repeat. Multiply those once.

Step-by-step explanation:

12 = 3*2*2

14 = 2*7

One 2 repeats

3*2*2*7 = 21*4 = 84

Lcm(12, 14) = 84

Answer:

(-2, 4)

Step-by-step explanation:

If you look at the quadrants on the graph, you could see that quadrant I holds only positive values (+, +). For quadrant II, it would hold (-, +) values. For quadrant III, it would hold (+, -) values. Lastly quadrant IV would hold (-, -) values.

So to answer the question, only (-2, 4) would be correct.

I also attached a graph of all the quadrants for you, just to understand the where all the positive and negative values are on the graph when it comes to quadrants.
