Step-by-step explanation:

Answer:

Its B

Step-by-step explanation:

60+60+60=180

Triangle=180

Answer:

11

Step-by-step explanation:

area = (side a + side b)/2 times height

side a = (2 times (area ÷ height)) - side b

side a = (2 times (54+6)) - 7

side a = (2 times (9)) - 7

side a = 18 - 7

side a = 11

to get the hypotenuse of the triangle

11 - 7 = 4

base of the triangle is 2 (2 on either side)

pythagorean theorem

a squared + b squared = c squared

4 + 36 = 40

to get c or the hypotenuse

take the square root of 40

Answer:

it's A

Answer:

x= 1.5

y=5

Step-by-step explanation:

do equation 1 and 2 then,

subtract the equation

find the value of y by subtracting

and put the value of y in any equation and get the value of x

Step-by-step explanation:

4x+3y=21

4x+2y=16

If we add both the equation:

4x + 3y = 21

4x + 2y = 16

(-) (-) (-)

4x + 3y = 21

-4x - 2y= -16

=> 0+1y= 5

y=5

substituting Y in eq 1

4x+3y=21

4x+3(5)=21

4x+15=21

4x=21-15

4x=6

x=1.5

Answer:

x=4

Step-by-step explanation:

In triangle MLK

it is a equilateral triangle

Hence

ML=LK=MK=5

Now come to triangle MKJ

It is a isosceles triangle

Hence

MJ=Mk

MK=5

Hence

Answer:

∠ ACB = 21°

Step-by-step explanation:

the inscribed angle ACB is half the central angle AOB , subtended by the same arc AB , then

∠ ACB = [tex]\frac{1}{2}[/tex] ∠ AOB = [tex]\frac{1}{2}[/tex] × 42° = 21°

Answer:

0.9219

Step-by-step explanation:

Starting at the deccimal point and going right, the places are: tenths (one decimal place), hundredths, thousandths, ten-thousandths. So that the number is ten-thousandths means it has four decimal places. Those digits are given in the problem "nine thousand two hundred nineteen"

Answer:

B. [tex]36\frac{3}{4}\ mph[/tex]

Step-by-step explanation:

The formula for average speed:

[tex]S_{average} = \frac{distance}{time}\\\\S = \frac{49\ miles}{1\frac{1}{3}\ hours}\\\\S = 36.75 = 36\frac{3}{4}\ mph[/tex]

Step-by-step explanation:

If r is 1/6 then we'll have 1/4*1/6+7/24.

Firstly we will multiply 1/4 and 1/6 which will give us 1/24.

Then we will add 1/24 and 7/24 which will give us 8/24.

Then we reduce it to it's lowest term that is 1/3.TRY THIS.

Answer:

x = 1, y = 6

or

x = 5, y = 2.

Step-by-step explanation:

y=x2−7x+12

y=−x+7

Substitute for y in the first equation:

- x + 7 = x^2 - 7x + 12

x^2 - 7x + x + 12 - 7 = 0

x^2 - 6x + 5 = 0

(x - 1)(x - 5) = 0

x = 1, 5.

When x = 1, y = -1 + 7 = 6.

when x = 5, y = -5+7 = 2.

100-40 = 60

Answer:

[tex]\frac{10x^2+3}{y^2+4}[/tex]

Step-by-step explanation:

When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )

So we have [tex]\frac{6x^2+5}{y^2+4} +\frac{4x^2-2}{y^2+4} =\frac{(6x^2+5)+(4x^2-2)}{y^2+4}[/tex]

==> remove parenthesis and apply signs

[tex]\frac{x^2+5+4x^2-2}{y^2+4}[/tex]

==> simplify numerator by combining like terms

[tex]\frac{10x^2+3}{y^2+4}[/tex]

and we are done!

Note:

like terms are terms with the same variable and exponent

An example of like terms are 6x^7 and 3x^7 as they have x as a variable and a power of 7

The like terms being combined here were (6x² and 4x²) and (5 and -2)

Answer:

[tex]\frac{10x^{2} +3}{y^{2}+4 }[/tex]

Step-by-step explanation:

[tex]\frac{6x^{2} +5}{y^{2}+4 } +\frac{4x^{2} -2}{y^{2}+4 }[/tex]

make the common denominator

[tex]\frac{6x^{2} +5+4x-2}{y^{2}+4 }[/tex]

combone the like terms

[tex]\frac{10x^{2} +5-2}{y^{2}+4 }[/tex]

subtract numbers

[tex]\frac{10x^{2} +3}{y^{2}+4 }[/tex]

E 0.52

Step-by-step explanation:

okay so total students who do chores in silence is 104 out of 200 students so u put that in a fraction, 104/200. divide top and bottom by 2 and u have 52/100 which is 0.52

Answer:

Step-by-step explanation:

so to go forward we input x and get out y,   to go backwards ( the inverse) we plug in y and get out x   ,  so just solve the equation for x

f(x) = 8x - 5

remember that f(x) = y

so,

y = 8x - 5

now solve for x

y+5 = 8x

(y+5) / 8 = x

then remember that we want to swap x and y ,

(x+5) / 8 = y

now y = [tex]f^{-1}[/tex](x),  it's kinda confusing.

 [tex]f^{-1}[/tex](x)= [tex]\frac{x+5}{8}[/tex]

How do we write 8x-2y=10 in slope intercept form?

[tex]\blue\textsf{\textbf{\underline{\underline{Answer and Solution:-}}}}[/tex]

First subtract 8x on both sides:-

-2y=10-8x

or

-2y=-8x+10

Now divide by -2 on both sides:-

y=2x-5

This is our equation in slope intercept form.

As m is a constant that is applied to x, it has to have something to do with minutes, eliminating A and B. As the constant is 2, it has to have something to with 2, eliminating D, meaning your answer is C. This is because a slope is the rate of change of y in relation to x, so it would be rate of change of y is a (a being your constant, in this case 2) per x. With your case, y is cost and x is minutes, leading to answer choice C.
