Find The Value Of X, Then Find EF.3x + 57x - 39X=EF=

Answers

Answer 1

Answer:

x = 8.8

EF = 22.6

Step-by-step explanation:

The given figure is of a rectangle.

We know that the opposite sides of a rectangle are parallel and equal.

So,

3x+5 = 7x-393x-7x = -39-5-5x = -44x = -44/-5x = 8.8

Now, finding EF

7x-397×8.8-3961.6-3922.6

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

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

Triangle abc is equiangular. If angle b is named as: -5x +5. What would be the value of x?

Answers

An equiangular triangle is simply a triangle with all interior angles equal to one another.

Therefore, b + b + b = 180 (angle sum of a triangle)

3b = 180

b = 60

But b = -5x + 5

Therefore,

60 = -5x + 5

-5x = 55

x = -11

Find (f•f)(3)

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.

Hi! Can anyone help please, I have been trying this problem for the past hour and I got slope-intercept equation like this but I don't know what to do y=1/2x+5

The graph of a function g is shown below. Find the following:

g(10)

Answers

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

y=1/2x+5

Slope=m=1/2

Y intercect=5

Now.

for g(10)

The coordinate is (10,8)

So

g(10)=8

You can kayak around Hamilton island in 3 hours. Kayaking together, you and your friend can kayak around the island in 1.4 hours. Let t be the time (in minutes) your friend would take to kayak around the island alone. Write and solve an equation to find t.

Answers

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

Sarah is making scarves. She has 10 1/2 yards of fabric to make the scarves. If each scarf requires 4 yards of fabric, how many scarves can Sarah make? PLEASE HELP ​

Answers

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.
