Answer:

D

Step-by-step explanation:

What we have to do is to find the arc tan

x/2 = arc tan (-1)

tan is negative on the 4th and second quadrant

arc tan (-1) = 135 or 315

pi is 180 degrees

so we have;

135 is 3 pi/4

multiplied by the 2

= 6 pi/4 which is 3 pi/2

315 is 7 pi/4 which is same as 7 pi/2 when we multiply by 2

Answer:

the answer is d

Answer:

24 degree Celsius

Step-by-step explanation:

Temperature may be defined as the intensity or the degree of heat that is present in any substance or present in the environment. It is the measure of hotness or coldness of any item or surroundings. Temperature is measured with the help of a comparative scale which shows the how hot or cold the place is or item is.

In the context, Riya uses a comparative scale like the thermometer to measure the temperature of the kitchen. The mercury level on the scale rises and stops at a point indicating the temperature of the kitchen.

Thus the temperature of the kitchen according to the scale is [tex]$24 ^ \circ C$[/tex].

Answer:

391.5

Step-by-step explanation:

Find the area of all the sides.

Triangles area: 9 X 10=90 because there are 2 so you don't need to divide by 2

Rectangles area: (9X10)X2= 180 because there is 2

Another rectangle area 13.5 X 9= 121.5

Add all:   90+180+121.5

Answer 391.5

Answer:

I think its 15^-7

Step-by-step explanation:

you can forget about the one and just look at the 15 and 7 which you get 15^-7

The fraction (1/15)⁷ can be written as 15⁻⁷ after using the properties of the integer exponent.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The number expression is:

= (1/15)⁷

As we know, from the definition of the integer exponent;  integer exponents are exponents that should be integers. It may be a positive or negative number.

After using the properties of the integer exponent:

= (15⁻¹)⁷

= 15⁻⁷

Thus, the fraction (1/15)⁷ can be written as 15⁻⁷ after using the properties of the integer exponent.

#SPJ2

Answer: The length of the fence will be 150 feet

Step-by-step explanation:

The question is asking you to find the hypotenuse of a rectangle with a length of 120 feet and a width of 90 feet. To find the hypotenuse we will need to use the formula   a^2 + b^2 = c^2

120 feet will be a

90 feet will be for b  

this is because a and b are the two legs of the rectangle.

120^2 + 90^2 = c^2

14400 + 8100 = c^2

22500 = c^2

   c =√22500

 c= 150

Step-by-step explanation:

First expression = 3y

second expression = 3 * 2 x

LCM = 3 * 2x * y = 6xy

i don't understand what your asking, but i hope this helps

Step-by-step explanation:

the process of ascertaining the variable value that makes the equation true is called 'solving' the equation. An equation is a verbalization that two quantities are equipollent. For exp/example:. x + 1 = 4 betoken that when we integrate 1 to the unknown value, 'x', the answer is equipollent to 4

Answer:

5,240 literate

1310 illiterate

Step-by-step explanation:

-ratio of literate : illiterate is 1:4

-add the numbers in the ratio (4+1=5)

-divide total population by 5 (6,550/5= 1,310)

-multiply the outcome by 4 to find the number of literate people (1,310*4=5,240 people)

-subtract the number of literate people from total population to find number of illiterate people (6,550-5,240= 1,310 people).

Answer:

10

Step-by-step explanation:

Answer:

Step-by-step explanation:

Length (L)= 2x - 3 cm

Breadth (b) = x + 7 cm

Area of the rectangle

= L * b

= ( 2x - 3)(x+ 7)

= 2x(x + 7) - 3(x + 7)

= 2x² + 14x  - 3x - 21

=( 2x² + 11x - 21) cm²

Answer:

[tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]

Step-by-step explanation:

Area of a rectangle = Length × Width

= (2x-3)(x+7)

Multiply 2x with x, 2x with +7, -3 with x and -3 with +7

= [tex]2x^{2}[/tex] + 14x - 3x - 21

= [tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]

Answer:

£208

Step-by-step explanation:

Given:

Height of solid box (h) = 20 cm

Width (w) = 80 cm

Length (l) = 10 cm

Cost of paint = £0.04 per cm²

Required:

Cost of painting the box

Solution:

✔️First, find the surface area of the box

Surface area = 2(l*w + l*h + w*h)

S.A = 2(10*80 + 10*20 + 80*20)

S.A = 2(800 + 200 + 1,600)

S.A = 2(2,600)

S.A = 5,200 cm²

✔️Find the cost of painting 5,200 cm² surface area of the box.

Cost of pianting 1 cm² = £0.04

Cost of painting 5,200 cm² = 5,200 × 0.04

Cost of painting the box = £208

Step-by-step explanation:

Given data

Total cupcakes sold= 300

we are told that 29% are mocha

Required

The amount of cupcakes that is vanilla

Let us find the amount that is mocha

Answer:

Step-by-step explanation:

3 x 2 = 6

Matt can make 6 different outfits with these clothes.

Combinations are the procedures used in mathematics to pick k things from n different items without replacement.

The following formula computes the combinations of k items from n:

(n, k) = n! / k!×(n-k)!

Given that Matt has 3 different colored T-shirts and 2 different colored shorts.

Matt can make 3 x 2 = 6 different outfits with these clothes.

This is because for each T-shirt color, he has 2 options for shorts, and he has 3 different T-shirt colors.

So for each T-shirt color, the number of outfit combinations is 2. And since he has 3 T-shirt colors, the total number of outfits is 3 x 2 = 6.

#SPJ5

Answer:

$24 and $16

Step-by-step explanation:

well let’s go through this step by step.

we have $40 which is the regular price, but not only do you want to find what 60% of 40 is, but you want to find out how big the difference is between the 2, in dollars. But i believe we can do that.

So let’s just think. Do you know how to get a percent of something? If so, ignore this next part.  If not, all you want to do is take 40 x 0.60. or whatever number you need. if it’s out of 100, that’s what you would do.

So now that we know how to get a percent of something, let’s find 60% of 40.

40 x 0.60 gives us 24, or in this case it’d be $24.

Great! we found the discount! now all we need to do is find out the difference.

All we need to do from here is take 40 - 24. what is 40 - 24?

16!

Now you’re done! the discount brings it down to $24 and the difference between the starting price and the discount price is 16 dollars.

i hope this was able to help you!

Answer: You'll have a quadrilateral with the following points

A diagram is posted below.

===================================================

Explanation:

The given quadrilateral has four unmarked points. I'll add the point labels A,B,C,D such that

I started at the lower right corner and worked my way clockwise.

----------------

Let's shift the line y = x-2 up two units so that it moves to y = x

We'll need to shift every point of the quadrilateral up two units as well.

So we have these new point locations after the shifting has occurred.

----------------

Now we need to reflect over the diagonal line. The rule to reflect over the line y = x is as simple as swapping the x and y coordinates.

So we can say [tex](x,y) \to (y,x)[/tex]

A point like (-3, 5) moves to (5, -3)

We have these new locations

----------------

The last thing to do is to shift everything down 2 units. This is to undo the first step we did when we shifted everything up by 2 units.

Doing this leads to these locations

Check out the diagram below.

Answer:

7g-2h

Step-by-step explanation:

5g+2g+h-34 = 7g-2h

original price is $240

Answer:

$240

Step-by-step explanation:

.75*x=180

This equation is setup so we can find the value of the original price, since 25% is deducted, you can multiply x by 75% and set it equal to 180 since that is the resulting discounted price.
