-0.85 - (-¼) + 0.4 + (-⅖) ?
what is the value of this expression?

Answer:

17.5

Step-by-step explanation:

[tex]15^{2}+9^{2}= 306\\[/tex]

[tex]\sqrt{306} = 17.5[/tex]

Answer:

x ≈ 17.5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² = 9² + 15² = 81 + 225 = 306 ( take the square root of both sides )

x = [tex]\sqrt{306}[/tex] ≈ 17.5 ( to the nearest tenth )

Answer:

24

Step-by-step explanation:

I guessed and checked but 24 -18 is 6 and 6 times 4 is 24

M + 18 = 4M

18 = 4M - M

18 = 3M

M = 18/3 = 6

4M = 4(6) = 24 sold by Luke

Answer:

196 square meters

Step-by-step explanation:

If the floor mat is square and one side is 14m then all sides are 14m. Given this you would find area by multiplying length by width.

L=14 W=14

14x14=196

There are 196 square meters

bIt was like any other day. I woke up to the sound of Fletchling in the trees. Wait is that the sound of Fletchling!? Am I still dreaming or have all my dreams just come true?............

​I did everything in my power to see if I was dreaming and I wasn’t. This was the start of a new beginning. I knew what had to happen next. Just then, Professor Oak walked in and my mom came into the room and said,”Charles I think you should stay here.”

But like any kid would do I didn’t listen.

​Then it all came back like a flood.

​I peeked out of a crack in my door and saw my mom and the Professor talking. I couldn’t tell what they were saying but there was a box on the table and it had my name on it. The addresser: Anonymous.

Answer: A is 88

Step-by-step explanation:

Sum of all angles is 180 degree.

Let the third interior angle be x.

38+50+x=180

88+x=180

x= 92

A and X are in linear pair.

A+X=180

A+92=180

A=88

Answer:

R 29

Step-by-step explanation:

tan x = 7.7/14 = 2.8.8

AC opposite

BC adjacent

AB hypotenuse

Answer:

R

Step-by-step explanation:

S and P would be too high

ABR makes the most sense

because x = 7.7/14 = 2.8.8

Step-by-step explanation:

Given

North Carolina has 12 fewer electoral votes than Florida

The total number of votes is 64

Suppose Florida receives [tex]x[/tex] votes

thus, votes received by North Carolina is [tex]y[/tex]

So, we can write

[tex]\Rightarrow x-y=12\quad \ldots(i)[/tex]

[tex]\Rightarrow x+y=64\quad \ldots(ii)[/tex]

Solving the above equations we get

[tex]x=38,y=26[/tex]

  32 feet

Step-by-step explanation:

0 seconds after launch, the rocket is still sitting on the tower. Its height is...

  y = -16(0^2) +57(0) +32

  y = 0 + 0 + 32 = 32

The rocket was launched from a tower 32 feet high.

Answer:

n= 11.65 years

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $33,000

Future Value (FV)= $15,000

Decrease rate (d)= 7%

To calculate the number of years it will take to reach $15,000; we need to use the following formula:

n= ln(FV/PV) / ln(1+d)  

n= ln(15,000/33,000) / ln(1.07)

n= 11.65 years

Answer:

5/9  

Step-by-step explanation:  

You have 10 movies in total. You take 1 out of 6 action movies. Now you have 5 action movies left, so that means the probability is 5/9. It's 5/9 because you chose 1 action movie out of 10 movies in total, so that means there are 9 movies in total left.

Step-by-step explanation:

A = 2πrh + 2π[tex]r^{2}[/tex]

d = 4

r = 4/2 = 2 cm

h = 9.5cm

A = 2π(2)(9.5) + 2π[tex](2)^{2}[/tex]  = 144.51326 [tex]cm^{2}[/tex]

Answer:

A is correct answer

Step-by-step explanation:

Here, we want to write an equation for a depreciation

The general form is;

V = I( 1 - r)^t

V is the present value in 2015

I is the initial value in 1990 which is 34,400

r is the decrease rate which is 1.7/100 = 0.017

t is the difference in years which is 2015-1990 = 25

Substituting these values, we have

V = 34,400(1-0.017)^25

V = 22,407.65 km^2

answer 2.5 i have solved the problem three times in my geometry class and got the same answer all three times

Considering the diagram below the value which represent the missing side, round to the nearest below, tenth, is 2 units.

Pythagoras theorem says that in a right angle triangle, the square of the hypotenuse side is equal to the sum of the square of the other two legs of right angle triangle.

The image of the given problem is attached below. In this diagram, the radius of the circle is 1.5 meter long.

The triangle ABC shown in the graph is right angle triangle as, the tangent of the circle is perpendicular with the radius of it at the point of contact.

Thus, by the Pythagoras theorem,

[tex](AB)^2+(BC)^2=(AC)^2\\(1.5)^2+(x)^2=(1.5+1)^2\\(x)^2=(2.5)^2-(1.5)^2\\x=\sqrt{6.25-2.25}\\x=\sqrt{4}\\x=2\rm\; units[/tex]

Thus, considering the diagram below the value which represent the missing side, round to the nearest below, tenth, is 2 units.

Every natural numbers represent subset of the integers because integers consists of positive and negative numbers and natural numbers are positive numbers 1 to infinity.

Answer:

Step-by-step explanation:

Since this is a rectangular prism, we need to do length × width × height to find the volume. Now despite the shape being tilted at an angle, nothing is different.

So we can see that the length is 25, the width is 18 and the height is 7

Rewrite the formula for volume replacing variables

25 × 18 × 7

Now solve.

25 × 18 = 450

450 × 7 = 3150

Now before we finalize our answer, there are two more things we need to do.

We need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

Add both of these to the end

3150 ft³ is your final answer
