Answer:

$192

Hope this helped!

(Also pls make me brainliest im trying to level up)

Answer:

192$ (sale price)

Step-by-step explanation:

First we have to find 20% of 240

240×20/100         We multiply 240 by 20/100 because a percent is always  over 100 (as a fraction)

(240×20/100=48)     Now that we know 20% of 240 we have to subtract

240-48=192

192$ is the sale price

Answer:

Answer:

Step-by-step explanation:

3. (1, 2)  (2, 4)

 (4 - 2)/(2 - 1)= 2/1 = 2

4. (5, 2) (10, 4)

    (4 - 2)/(10 - 5) = 2/5

5. (4, 1) (8, 2)

   (2 - 1)/(8 - 4) = 1/4

6. (0, 0)  (1, 20)

   (20 - 1)/(1 - 0)

   20/1= 20

Answer:

90

Step-by-step explanation:

Quarters , q = 25 cent

Nickel, n = 5 cent

3 times as many nickels as quarters;

n = 3q

Total value of coins = $12

n + q = $12

0.05n + 0.25q = 12

0.05(3q) + 0.25q = 12

0.15q + 0.25q = 12

0.40q = 12

q = 12 / 0.40

q = 30

n = 3q

n = 3(30)

n = 90

90 nickels

Answer:155

Step-by-step explanation:

because they are parallel lines. If the angles differed even by 1°, eventually the lines would meet, therefore they would not be parallel.

Answer:

Firstly angle 6 and 2 are equal because of corresponding angles

so 6 = 2

Now angle 1 + 2 = 180 ( linear pair)

angle 1 = 180 - 55

1 = 125

Answer:

9/20

Step-by-step explanation:

I hope this helps :)

Answer:

9/20

Step-by-step explanation:

In order to subtract fractions you need to find the least common denominator.  Since the LCD is 20 (4 times 5 or 10 times 2) you need to multiply each fraction by 1 to get the denominators the same.

3/4 times 5/5 = 15/20

3/10 times 2/2 = 6/20

now you can subtract!

15/20 - 6/20 = 9/20

you can not simplify this, so your final answer is 9/20

Answer:

The answer is 1

Step-by-step explanation:

to calculate the slope m use the

gradient formula

m = y2 - y1/x2 - x1

let (x1, y1) = (4, 9) and (x2, y2) = (1, 6)

⇒ m = 6 - 9/1 - 4 = -3/-3 = 1.

(31.217,31.563) is the answer

Answer:

= 1 6  u need to simplyfy the question

X/2 = 8

▶ ️2 = 8 × X. (transposing X to RHS )

▶️ 2 = 8X

▶ ️X = 8/2. (transposing 2 to RHS )

▶️ X = 4

hence the value of X is 4.

Answer ad Step-by-step explanation:

C is the answer.

In which x is greater than or equal to 1.

That is where it is increasing.

#teamtrees #PAW (Plant And Water)

Answer:

C

Step-by-step explanation:

The answer is C because it increases at the 1 on the X-Intercept but then the arrow continues but it never ends so X is greater than 1 or its equal to it

Answer:

I don't know but maybe 3 in a half

Answer:

3 1/6

Step-by-step explanation:

Since it says HOW MANY MORE, you need to subtract.

Answer:

m<EDC=110

Step-by-step explanation:

angle c is 35 degrees too, because this is isoceles

using the sum of the triangle's angles which are always 180

70+x=180

x=110

Answer:

x+2y-10=0

x=10-2y

x=10

Given:

A chess club with 45 members is electing a new president.

Bob received 18 votes.

To find:

The percentage of the club members who voted for Bob.

Solution:

We have,

Total number of members = 45

Votes received by bob = 18

Now, the percentage of the club members who voted for Bob is

[tex]\%=\dfrac{\text{Number of members voted for bob}}{\text{Total members}}\times 100[/tex]

[tex]\%=\dfrac{18}{45}\times 100[/tex]

[tex]\%=\dfrac{2}{5}\times 100[/tex]

[tex]\%=\dfrac{200}{5}[/tex]

[tex]\%=40[/tex]

Therefore, 40% of the club members voted for Bob.

Answer:

y = 13

Step-by-step explanation:

If x = -7, plug the number in the equation

y = -(-7) + 6

-(-7) is equal to -1 x -7 which equals 7

y = 7 + 6

y = 13

Answer:

Step-by-step explanation:

L and W are the length and width of the flag.

"The perimeter of the flag is 500 feet"

2L + 2W = 500

L+W = 250

"The length is 30 feet greater than the width"

L = W+30

You have a system of two equations:

L+W = 250

L  = W+30

Substitute W+30 for L:

(W+30) + W = 250

2W + 30 = 250

2W = 220

W = 110 ft

L = W+30 = 140 ft

:::::

"C is 400 miles longer than D"

C = D+400

"The sum of their lengths is 5,580 miles"

C + D = 5,580

You have a system of two equations:

C = D+400

C + D = 5,580

Substitute D+400 for C:

(D+400) + D = 5,580

2D + 400 = 5,580

D = 2,590 miles

C = D+400 = 2,990

Answer:

[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]

Step-by-step explanation:

The missing details are:

[tex]T= (0,4)[/tex]

[tex]M = (\frac{9}{4}, \frac{5}{4})[/tex] --- Midpoint of ST

Required

Determine the coordinates of S

To do this, we apply the mid-point formula:

[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

Where

[tex]M(x,y) = (\frac{9}{4}, \frac{5}{4})[/tex]

[tex]T(x_1,y_1) - (0,4)[/tex]

The equation becomes:

[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(0+x_2,4+y_2)[/tex]

[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(x_2,4+y_2)[/tex]

Multiply through by 2

[tex]2*(\frac{9}{4},\frac{5}{4}) = 2*\frac{1}{2}(x_2,4+y_2)[/tex]

[tex](\frac{9}{2},\frac{5}{2}) = (x_2,4+y_2)[/tex]

By comparison:

[tex]x_2 = \frac{9}{2}[/tex]

[tex]4 + y_2 =\frac{5}{2}[/tex]

[tex]y_2 =\frac{5}{2}-4[/tex]

[tex]y_2 =\frac{5-8}{2}[/tex]

[tex]y_2 =-\frac{3}{2}[/tex]

Hence, the coordinates of S is:

[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]
