A handyman is tiling a bathroom l. He needs 34 rows of 18 tiles to cover the floor. How many total tiles does he need to cover the floor

Answer:

Step-by-step explanation:

Let's write a system.

Let's say that the variables are x and y.

xy=48

x+y=14

Solve for one of the variables, let's say, x.

x=14-y.

Now substitute x into the 1st equation.

(14-y)y=48

Simplify.

-y²+14y=48

Make it into a quadratic equation.

-y²+14y-48=0

Make sure y²'s coefficient is one. Divide everything by -1

y²-14y+48=0

Now factor!

What factors add up to 14 and multiply to 48.

6 and 8!

Since the 2nd term is negative, and the 3rd term is positive, the factors have to be negative.

y²-6y-8y+48=0

Group.

(y²-6y)+(-8y+48)=0

y(y-6)-8(y-6)=0

(y-8)(y-6)=0

y-8=0

y-6=0

y=8 y=6

now let's substitute each y value into y²-14y+48=0

8²-14(8)+48=0

64-112+48=0

0=0. so y=8 checks out!

6²-14(6)+48=0

36-84+48=0

0=0 so y=6 also checks out!

Choose one y value and solve for x, in each equation :

xy=48

x+y=14

8x=48

x+8=14

x=6

x=6

It checks out!

so the factors are

x=6 y=8.

Answer:

[tex]E(n)=75000 \times 2^n[/tex]

Complete question:

write a function that gives mapiyas cumulative earnings E(n), in dollars when she has written n sequel's

Step-by-step explanation:

According to the question, she earned $75000 for the first book.

Also,We are  given that her cumulative earnings double with each sequel that she writes.

Assuming she has written n sequel's

Now since we are given that her cumulative earnings double with each sequel

So, her initial earning will be [tex]2^n[/tex] times

So, her earning will be : [tex]75000 \times 2^n[/tex]

Now we are given that cumulative earnings is denoted by E(n)

So, the function becomes :[tex]E(n)=75000 \times 2^n[/tex]

Hence a function that gives Mapiya's cumulative earnings E(n), in dollars when she has written n sequel's  is  [tex]E(n)=75000 \times 2^n[/tex]

Answer:

11.

Step-by-step explanation:

Because you wanted to find the second term, just substutite n=2 into the formula.

Thus, 3(2)^2 - 1 = 3(4) - 1 = 11

Answer:

Step-by-step explanation:

We get the second term by just plug in 2 (instead of n) in the sequence formula:

second term = 3×(2)² - 1 = 11

Answer:

m<5 = 95 degrees

Step-by-step explanation:

Let's first find m<1

=> m<1 = 180-85

=> m<1 = 95 degrees

Since,

m<1 = m<5 (Corresponding angles)

So,

m<5 = 95 degrees

Answer:

y = 5/6x +1

Step-by-step explanation:

5x - 6y = -6

We want the equation in the form

y = mx+b where m is the slope and b is the y intercept

Subtract 5x from each side

5x -5x - 6y =-5x -6

-6y = -5x -6

Divide each side -6

-6y/-6 = -5x/-6  -6/-6

y = 5/6x +1

Answer & Step-by-step explanation:

The problem tells us that ΔABC ≅ ΔDEF. Since we know that this is true, then we also know that ∠A ≅ ∠D, ∠B ≅ ∠E, and ∠C ≅ ∠F.

So, since we are looking for the measurement of ∠F, then all we have to do is know the measurements of ∠C because they are congruent angles.

So, the measurement of ∠F is 63°

Answer:

The overall change in temperature over the time period ∆T = -12.6°F

Step-by-step explanation:

Rate of change of temperature r = -2.8°F per hour

Time t = 4.5 hours

The overall change in temperature ∆T = Rate of change of temperature × time period

∆T = r × t

∆T = -2.8°F per hour × 4.5 hours

∆T = -12.6°F

The overall change in temperature over the time period is -12.6°F

Answer: -12.6

Correct option: Second one -> 141.3 cm3

Step-by-step explanation:

The volume of "snow" is the sum of the half sphere volume and the cone volume.

The volume of the half-sphere is given by the formula:

V = (2/3) * pi * radius^3

If the half sphere has a radius of 3 cm, we have that:

V1 = (2/3) * pi * 3^3 = 56.5 cm3

The volume of the cone is given by:

V = (1/3) * pi * radius^2 * height

If the radius is 3 cm and the height is 9 cm, we have:

V2 = (1/3) * pi * 3^2 * 9 = 84.8 cm3

So the final volume is:

V = V1 + V2 = 56.5 + 84.8 = 141.3 cm3

Correct option: Second one

Answer: D

Step-by-step explanation:

Distributive Property is when you want to apply to FOIL method when you are multiplying out the expression. You would have multiple number/terms to multiply out to. The only answer choice that shows this is D.

In D, you are distributing the 5 to 8 and -2. So, you are multiplying 5×8=40 and 5×-2=-10. Then you have 40-10.

A is just multiplying, 5 and 1/5.

B is just multiplying 5 and 1.

C is just Associative Property, changing the parenthesis.

D  shows Distributive Property.

Answer:

Explanation:

C is the not the answer because when there is a minus sign with a number in front of the parenthesis, the numbers in the parenthesis will bave to be solved instead of distributed.

B is not the answer because there are not even parenthesis to empasise the distibution.

A is not the asnwer because the numbers are simply being canceled out into the number 1 with a fraction and a whole number.

Answer:

y = 9/4x.

Step-by-step explanation:

According to slope-intercept form, y = mx + b where m is the slope and b is the y-intercept.

So, y = 9/4x + 0

y = 9/4x.

Hope this helps!

The required equation of the line is given as 9/4x with a slope of 9/4 and a y-intercept of 0.

Given that,
The linear equation represents a line with a slope of 9/4 and a y-intercept of 0 is to be determined.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

here,
Standard equation of the line,
y = mx + c
Put , = 9/4 and c = 0
y = 9/4x + 0
y = 9/4x

Thus, the required equation of the line is given as 9/4x.

Step-by-step explanation:

586 divide by 4 is 146.5 so then i rounded to make it 147 then subtracted the points she already had (58) which led me to 89

Answer:

132 questions

Step-by-step explanation:

First, let’s find how many more points she needs.

To find this, find the difference between the points she needs and the points she has.

points needed- points gained

She needs 586 points and already has 58 points.

586 points-58 points

528 points

Now, we need to find how many questions she needs to answer correctly.

She needs 528 points and every correct question is worth 4 points.

Therefore, we can divide 528 by 4 to find how many questions she must answer correctly.

528/4=132

132 questions

She must answer 132 questions correctly to pass the test.
