Answer:

£720

Step-by-step explanation:

100+5 = 105

105% = 756

divide both sides by 105 to find 1%

1% = 7.2

multiply both sides by 100 to find 100%

100% = 720

756/105 X 100 = 720

1 is a right triangle I know this because a right triangle is a triangle which one of the angles is a 90 degree angle

Answer:

Triangles 1,2,3, and 4 are all right triangles

Answer:

The two angles are 10 degrees and 170 degrees.

Step-by-step explanation:

Supplementary angles add up to 180 degrees.

Let the angle be called "x", and the supplementary angle be called "180-x"

Converting words to math: x-160=180-x

Add x to both sides: 2x-160=180

Simplify: 2x=20

Divide by 2: x=10

Let me know if this helps!

Answer:

0.16

Step-by-step explanation:

4*5*1=20

9*7*2=126

20/126=10/63

Answer:

10/63

Step-by-step explanation:

First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.

Answer:

No

Step-by-step explanation:

I think you meant to put 5/12 ad 9/16 but in any case, even if it were 51/2 and 91/6 or anything else, the answer would be no

Answer:

[tex]x < - 21[/tex]

Step-by-step explanation:

1. Multiply both sides by 3.

[tex]x < - 7 \times 3[/tex]

2. Simplify 3 × 7 to 21.

[tex]x < - 21[/tex]

therefor, the answer is x < -21

Step-by-step explanation:

f(3)=3^2-3/2=3*3-3/2=9-3/2=18/2-3/2=15/2

Answer:

n = 1

Step-by-step explanation:

So the first step is to simplify the top equation:

(3v + 7) - (8v + 6)

distribute the negative sign to get rid of the second parentheses:

3v + 7 - 8v - 6

now, combine like terms

-5v + 1

Since it says it needs to be equivalent to (-5v + n), n is 1

Answer:

x = -11

m<B = -43

m<C = -22

Step-by-step explanation:

To solve for x, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.

I hope this is correct and helps!

Answer:

1. slope m = 1; y-intercept b = 3

2. slope m = ; y-intercept b = 4

3. slope m = 3; y-intercept b = 1

4. slope m = [tex]\frac{1}{2}[/tex]; y-intercept b = 1

5. the slope demonstrates the cost of toppings PER topping and how the price increases per topping. the y-intercept is the starting cost WITHOUT toppings (when toppings = 0) and the slope increases the price starting with the y-intercept because it is the initial cost. the graph is attached

Finding the volume of these composite figures involves finding the volume of each shape, calculate the volume of each shape,

Step-by-step explanation:

then adding the volume of these different shapes together.  the volume of two different figures is calculated with step by step directions.

Answer:

b

Step-by-step explanation:

[tex] \begin{cases} x - y = - 2 \\ 4x - y = 4 \end{cases}[/tex]

Simply multiply the negative one in one of the equations.

[tex] \begin{cases} - x + y = 2 \\ 4x - y = 4 \end{cases}[/tex]

We can finally eliminate the y-term by adding both equations.

[tex]( - x + 4x) + (y - y) = 2 + 4 \\ 3x + 0 = 6 \\ 3x = 6 \\ x = \frac{ 6 }{3} \longrightarrow \frac{ \cancel{6}}{ \cancel{3}} = 2 \\ x = 2[/tex]

[tex]x - y = - 2 \\ 2 - y = - 2 \\ 2 + 2 = y \\ 4 = y[/tex]

First Equation

[tex]x - y = - 2 \\ 2 - 4 = - 2 \\ - 2 = - 2 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]

Second Equation

[tex]4x - y = 4 \\ 4(2) - 4 = 4 \\ 8 - 4 = 4 \\ 4 = 4 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]

Hence, the solution is (2,4).

[tex] \begin{cases} x = 2 \\ y = 4 \end{cases}[/tex]

Coordinate Form

Answer:55

Step-by-step explanation:

Answer:

Option (2)

Step-by-step explanation:

Explicit formula of an arithmetic sequence is always in the linear form.

A(n) = a + (n - 1)d

Here A(n) = nth term of the sequence

a = first term

n = number of term

d = common difference

Formula doesn't have the terms with the exponent.

Therefore, from the given options, expression that represents an arithmetic sequence will be,

f(n) = 3n - 4

Option (2) will be the correct option.

− 108 x 5 y 7

Step-by-step explanation:

My computer wont allow it but the 5 and the 7 are exponents

Answer:

[tex]-108x^{5}y^{7}[/tex]

Step-by-step explanation:

Simplify using the laws of exponents (there are more rules than listed, these given rules are just the ones that come into play here);

- when there is a term in parenthesis with an exponent outside, the term's exponent gets multiplied by the exponent outside

- when multiplying two exponents, one can only combine terms with the same base, and one must add the exponents

[tex](3xy^{2})^{3}*(-4x^{3}y)\\\\=(3^{3}*x^{3}*y^{2{^{3}}}) *(-4x^{2}y)\\\\=(27x^{3}y^{6})(-4x^{2}y)\\\\=-108x^{5}y^{7}[/tex]
