:(

Answer:

4x^2-21x-18

Step-by-step explanation:

Hi there!

[tex]\large\boxed{-18a^{3}c^{3}}[/tex]

To solve, keep in mind the following property:

xᵃ · xᵇ = xᵃ⁺ᵇ

We are given:

-3a⁷ (6)c⁷a⁻⁴c⁻⁴

Combine like exponent bases using the property above:

-3(6)a⁷⁻⁴c⁷⁻⁴

Simplify:

-18a³c³

His profit was 15% of Rs 225, which comes to 0.15(Rs 225), or Rs 33.75

Answer:

A= 314.16m^{2}

Step-by-step explanation:

if its a half a circle then we use the formula to find area of a circle and get half of it.

[tex]A=\pi r^{2}[/tex]

[tex]A=\pi 10^{2}[/tex]

[tex]A= 314.16m^{2}[/tex]  

Answer:

49(pi)

Step-by-step explanation:

Area of a circle = (pi)r squared

= 7 squared (pi)

= 49(pi)

= 49 x pi

Answer:

49(pi)

Step-by-step explanation:

Answer:

We know that

V = πr²h

400 = 22/7 × r² × 8

400 × 7 = 22 × 7r²

2800 = 154r²

2800/154 = r²

18 ≈ r²

4.2 = r

Answer:

tan ∅ = 16/12

Step-by-step explanation:

Once again here are the trigonometric ratios

Sin = Opposite over Hypotenuse

Cos = Adjacent over Hypotenuse

Tan = Opposite over Tangent

We are asked to find tan ∅

Looking at the trigonometric ratios we see that tan = opposite over adjacent

So we find the side length opposite of the indicated angle (∅) which would be 16 then we find the angle adjacent angle ( the side that is not the hypotenuse nor the opposite ) so the adjacent of angle ∅ is 12

so tan ∅ = opposite (16) over adjacent (12)

tan ∅ = 16/12

Answer:

The answer is "(4, -5)".

Step-by-step explanation:

Please find the complete question in the attached file.

In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is [tex](x, y) \longrightarrow (y, -x)[/tex]

Putting the value in x = 5 and y = 4 then:

[tex](5, 4) \longrightarrow (4, -5)[/tex]

Answer: c

Step-by-step explanation

Answer:

As 252 has more than two factors, this makes it a composite number. As the sum of digits of 252 is 9, it is divisible by 3 as well as 9. Hence, 3 and 9 are factors of 252.

Answer:

the answer 4

Step-by-step explanation:

4 of each because (1.25x4) + (1.50x4) = 11.50

Answer:

Sally bought 6 sodas and 2 cups of coffee.

Step-by-step explanation:

Variable x = number of sodas

Variable y = number of coffees

$1.50x + $1.25y = $11.50

x + y = 8 drinks

$1.50(6) + $1.25(2) = $11.50

$9.00 + $2.50 = $11.50

I simply plugged in numbers that totalled to 8 drinks until I reached $11.50 as the total.

For example:

$1.50(5) + $1.25(3) = $11.50

$7.50 + $3.75 = $11.50

$11.25 = $11.50

This is not correct as they do not equal so this cannot be the answer.

Answer:

95.0

Step-by-step explanation:

Area of a circle

A = πr2

Radius is half the diameter = 11/2 = 5.5

A = π x 5.5 x 2

= 95.033177...

= 95.0

Answer:

The first person to arrive is not random. The person that mostly arrives first every time is the person who lives closest to the school, or is a teacher's pet.

The odds of the person who lives 20km away from the school being first are way lower than anyone else.

A better method, would be everyone writes their name on a paper, and the teacher picks one at random from a hat.

Answer:

B, C, D

Step-by-step explanation:

7x + 1 + 105 = 180

7x = 74

x = 74/7

4y + 14 + 7y + 1 = 180

11y = 165

y = 15

m<A = 4y + 14 = 4(15) + 14 = 74°

m<B = 7x + 1 = 7(74/7) + 1 = 75°

m<C = 7y + 1 = 7(15) + 1 = 106°

Answer:Michelle

And 50

Step-by-step explanation:

Answer:

I think C

so it's kind of a process of elimination you have to see the order of the numbers and what order each number is in so for A you can see that it's 345 is greater than 354 which is inspect cuz 354 is greater than 345 for B that's an obvious answer is is 400 is less than 40 which is obviously wrong because 400 is greater has two zeros and 40 only has one 0 for C it has 4008 is less than 4080which is actually correct if you look at the way that the numbers are written you could see that 80 is greater than 8 D it's obviously not correct because it says 20090 is equal to 23009 which is incorrect because 90 is greater than 9

Answer: 121°

Step-by-step explanation:

The measure of angle B will be [tex]121^0[/tex] .

Angle is formed by two rays lie in the plane that contains the rays.

We have,

[tex]m \angle A =(6x-19)^0[/tex]

Now,

Linear pair angles are those angles whose sum is [tex]180^0[/tex] .

i.e.

[tex]m \angle A + m \angle B=180^0[/tex]

So,

[tex](6x-19)^0 +(11x-22)^0 =180^0[/tex]

Now,

[tex]17x-41=180[/tex]

[tex]17x=221[/tex]

[tex]x=13[/tex]

So,

[tex]m\angle B=(11x-22)^0[/tex]

Putting value of x;

[tex]m\angle B=(11*13-22)^0[/tex]

[tex]m\angle B=(121)^0[/tex]

So, measure of angle B is [tex]121^0[/tex].

Hence, we can say that the measure of angle B will be [tex]121^0[/tex] .

Answer:

x = -4 3/16.

Step-by-step explanation:

First, convert -27/8 to a mixed number. -3 3/8.

So we can take 5 + 2x = -3 3/8 and subtract 5 from both sides (to get rid of the 5 on the left)

The equation turns into this: 2x = -8 3/8.

Now we can divide by 2 on both sides.

The equation becomes x = -4 3/16.

Hope this helps!

Answer: No

Step-by-step explanation:

The problem says x is bigger than 5, and smaller than or equal to 9.

Possible values of x can only be 6,7,8, and 9.

So, 12 cannot be the answer.
