Answer:

Step-by-step explanation:

From your knowledge of multiplication tables, you know ...

  48 = 6·8 = 3·2·2·2·2 = 3·2^4 . . . . a = 4

  56 = 7·8 = 7·2·2·2 = 7·2^3 . . . . . . b = 3

Answer:

x = 15.9

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + x^2 = 17^2

36+ x^2 = 289

x^2 = 289-36

x^2 =253

Take the square root of each side

sqrt(x^2) = sqrt( 253)

x = 15.90597

Rounding to the nearest tenth

x = 15.9

Answer:

[tex]y = \frac{4}{5} x - \frac{22}{5} [/tex]

Step-by-step explanation:

[tex]y = mx + b[/tex]

[tex] - 2 = \frac{4}{5} (3) + b \\ - 2 = \frac{12}{5} + b \\ - 2 - \frac{12}{5} = b \\ - \frac{10}{5} - \frac{12}{5} = b \\ - \frac{22}{5} = b[/tex]

Therefore, the equation of the line that goes through point (3, -2)and has slope ⅘ is

[tex]y = \frac{4}{5} x - \frac{22}{5} [/tex]

Answer:

$8

Step-by-step explanation:

If the first 3 students spend $24 on food total, and they split the bill equally, each of the 3 paid $8. We know this because 24 ÷ 3 = 8.

Answer:

4 bags, or 4 1/4 bags

Step-by-step explanation:

change 3 1/2 into a improper fraction, then change it to have a common denominator as 3/4. the expression would then be (14/4 + 3/4) divided by 1/2. 17/4 divided by 1/2 is 4 1/4. it would depend if they meant to fill the whole bag.

Answer:

[tex] \sqrt{54} = \sqrt{9 \times 6} = 3 \sqrt{6} [/tex]

Step-by-step explanation:

The angles of rectangle add up to 360°

So the missing angle + 65 + 110 + 87 = 360

The missing angle + 262 = 360

The missing angle = 98°

please give me a brainliest answer

Step-by-step explanation:

? + 65°+ 110°+87° = 360°

? + 262° = 360°

? + 262 -262° = 360° - 262°

? = 98°

Answer:

f(-2) =  -5

Step-by-step explanation:

Actually, the function g(x) is irrelevant here.  We need only evaluate the function f(x) = 3x + 1 at x = -2:

f(-2) = 3(-2) + 1 = -6 + 1 = -5

f(-2) =  -5

Answer:

x=55*

y=125*

Step-by-step explanation:

In parallel lines, opposite angles are equal to each other so x=55.

In lines, adjacent (side by side) angles always add up to 180 so,

x+y=180

55+y=180

y=180-55

y=125

Answer:

6,500

Step-by-step explanation:

Discount = 20%

Therefore the cost price is 100 - 20 = 80%

so,

£5,200 = 80%

To find the 100% ( the cost of the car before the discount), invert the fraction.

100/80 x 5200/1 = 6,500

Answer:

The slope of (6, 5) and (3, 7.5) is 5/-6.

As a decimal: (-0.83333333333...)

Step-by-step explanation:

Formula for slope:

[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]

('m' means slope.)

[tex](x^1,y^1) =[/tex] coordinates of the first coordinate point

[tex](x^2,y^2)=[/tex] coordinates of the second coordinate point.

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

Coordinates:

[tex](6,5)(3,7.5)[/tex]

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

Now, I will simply plug the numbers into the formula.

[tex]m=\frac{7.5-5}{3-6} =\frac{2.5}{-3} =5/-6[/tex]

As a decimal: (-0.83333333333...)

The slope of the given points is 0.833

Slope, m, is given by the formula

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

From the question

[tex]x_{1} = 6[/tex]

[tex]y_{1} = 5[/tex]

[tex]x_{2}=3[/tex]

[tex]y_{2}=7.5[/tex]

Putting the above parameters into the formula

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

We get

[tex]m =\frac{7.5-5}{3-6}[/tex]

∴ [tex]m= \frac{2.5}{-3}[/tex]

[tex]m = 0.833[/tex]

Hence, the slope of the given points is 0.833

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

let the number be n , then

4 - 4n = 2n ( add 4n to both sides )

4 = 6n ( divide both sides by 6 )

[tex]\frac{4}{6}[/tex] = n

The number is [tex]\frac{2}{3}[/tex]

Answer:

Let the number = x
