4 to the power of -1

Answers

Answer 1

Answer:

0.25

I hope this helps!

Answer 2

Answer:

1/4

Step-by-step explanation:

Negative exponents basically flip the number upside down,

so 4 ^ -2 would be 1/4^2

where the four has a power of 2.

The answer would therefore be 1/16

Numbers to the power of 1, is just the same number, so if you have negative exponents, it would be the same 4, except flipped over.

Solve for missing angle

Answers

Answer:

so the exterior angle 152 is made from the interior angle being subtracted from 180. we can also subtract 152 from 180 to find the interior angle. 180-152=28  the inside of a triangle is a total of 180 degrees so 110+28=138 180-138=42 degrees. 42 degrees is the final interior angle and the missing and the missing exterior angle is congruent to the 42 degree angle. So the missing exterior angle is 42 degrees

The local furniture store pays $300 for a dining room table and sells it with a 40% markup.
What is the selling price of the dining room table?

Answers

Answer:

$420

Step-by-step explanation:

The wholesale price is $300 and the markup is 40% of that, or

0.40($300) = $120

and so the selling price is $300 + $120 = $420

An easier way to calculate this is to multiply $300 by (1.00 + 0.40), or (1.40), which again comes out to $420.

The cost C , in £, of a monthly phone contract is made up of the fixed line rental L , in £, and the price P , in £ ,of the calls made. Enter a formula for the cost and, enter the cost if the line rental is £10 and the price of calls made is £28.

Answers

Answer:

C = L + P

C = £38

Step-by-step explanation:

Given that :

Cost (C) is given by :

Sum of fixed line rental (L) ; price (P) of calls made.

Hence,

Cost formula;

C = L + P

Cost if the line rental is £10 and the price of calls made is £28.

C = L + P

If L = £10 ; P = £28

C = £10 + £28

C = £38

Naoko is building a small art shed in the backyard. She created a blueprint of the floor plan with a scale of 1⁄4 in. To 1 ft. According to the blueprint, the art space has dimensions of 2 1/2 in. By 1 in. What are the dimensions of her art shed in feet?

Answers

Answer: 10 feet by 4feet

Step-by-step explanation:

From the question, we are informed that Naoko is building a small art shed in the backyard and that she created a blueprint of the floor plan with a scale of 1⁄4 in. to 1 ft. This means that 1 inch will be to 4 feet.

Since the art space has dimensions of 2 1/2 in. by 1 in. This will be:

= (2 1/2 × 4) by (1 × 4)

= 10 feet by 4 feet

The dimensions of her art shed in feet are 10 feet by 4 feet.

not congruent

Step-by-step explanation:

These two triangles are not congruent because for two shapes to be congruent to each other, both needs to have same shape and size and clearly, we can see in this figure that both triangles although are the same shape, are different sizes so therefore these two triangles are not congruent. For example, the height of triangle ADE is 4 whereas the height of triangle CBA is 2.

Fitness For cardiovascular exercise, you do a combination of walking and running
for 60 minutes. During the 60 minutes, you end up running twice as much as
walking. Let x represent the number of minutes you ran and y represent the
number of minutes you walked. How many minutes did you run and how many
did you walk?

Answers

Answer:

You walked for 20 minutes and ran for 40 minutes

Step-by-step explanation:

System of Equations

Let x = the number of minutes you ran

y = the  number of minutes you walked

Walking and running takes a total of 60 minutes, thus:

[tex]x+y=60\qquad\qquad [1][/tex]

Running time is twice as much as walking time, thus:

[tex]x=2y\qquad\qquad [2][/tex]

Solve the system by substitution. Taking x from [2] and substitute in [1]:

2y+y=60

Simplifying:

3y=60

Solving:

y=60/3=20

Calculate x from [2]:

x=2*20=40

You walked for 20 minutes and ran for 40 minutes

thank you

Answers

Answer:

f(-2) = 4

f(0) = 6

f(5) = 11

Step-by-step explanation:

You just need to plug in the different values of x into the equation

f(x)=x+6

When x = -2, then f(-2) = -2 + 6 = 4

When x = 0, then f(0) = 0 + 6 = 6

When x = 5, then f(5) = 5 + 6 = 11

f(5) = 11 , f(0) = 6 , f(-2) = 4

Given expression:

f(x) = x + 6

Find:

f(−2), f(0), f(5)

Computation:

f(x) = x + 6

When x = -2

f(-2) = -2 + 6

f(-2) = 4

When x = 0

f(0) = 0 + 6

f(0) = 6

When x = 5

f(5) = 5 + 6

f(5) = 11

TV Cabinet TV screens are measured on the diagonal. If we have a TV-cabinet that is 72 inches long and 64 inches high, how large a TV could we put in the space (leave 2-inches on all sides for the edging of the TV)? Round your answer to the nearest tenth.

Answers

Answer:

94in

Step-by-step explanation:

We are expected to solve for the diagonal of a rectangular shape.

given that the length, l=72in

width, w=64in

we can apply the Pythagoras theorem to solve for the diagonal since it corresponds to the hypotenuse of the rectangle

note: we are to leave 2-inches on all sides for the edging of the TV

l=72-2= 70 in

w=64-2=62

diag=√l^2+w^2

diag=√70^2+62^2

diag=√4900+3844

diag=√8744

diag=93.50 in

to the nearest tenth, it is 94in
