person 6-9 MathXL 8th grade question 2​

Step-by-step explanation:

I'm going with the 41....I'm not sure if it's right..

Answer:

C

Step-by-step explanation:

Using the sine ratio in the right triangle

sin x° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{13}{20}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{13}{20}[/tex] ) ≈ 41° ( to the nearest degree )

Step-by-step explanation:

Answer:

coupon A

Step-by-step explanation:

coupon A 45%÷100=0.45 so 0.45×47= gives 21.15. coupon B 25÷2=23.50 so that the solution the lower price is coupon A $21.15

Answer:

[tex] \large \boxed{ \boxed{ \tt{g(4) = - \frac{16}{3} \longrightarrow \: \: Improper \: \: Fraction \: \: }}} \\ \large \boxed{ \boxed{ \tt{g(4) = - 5 \frac{1}{3} \longrightarrow \: \: Mixed \: \: Fraction \: \: }}}[/tex]

Step-by-step explanation:

We are given the function below:

[tex] \large{g(x) = \frac{4x}{3x - 15} }[/tex]

To find g(4), we simply substitute x = 4 in the equation.

[tex] \large{g(4) = \frac{4(4)}{3(4) - 15} }[/tex]

Then evaluate the value and simplify in the simplest form.

[tex] \large{g(4) = \frac{16}{12 - 15} } \\ \large{g(4) = \frac{16}{ - 3} } \\ \large{g(4) = - \frac{16}{3} }[/tex]

Therefore, the value of g(4) is - 16/3

Mixed Fraction Form

[tex] \large{g(4) = - 5 \frac{1}{3} }[/tex]

Answer:

The answer should be 18.

Answer:

plot x in -3 1/2 from the origin(to left, so put it in middle of -3 and -4)

plot y in 2 1/4 from the origin(to up, so put it in 2 1/4)

Hope this helped, if you have questions; feel free to ask in comments!

Step-by-step explanation:

Given:

The factors of the quadratic function g(x) are (5x-1) and (x+4).

To find:

The solutions to the equation g(x)=0.

Solution:

If the factors of the quadratic function g(x) are (5x-1) and (x+4), then the function is defined as:

[tex]g(x)=(5x-1)(x+4)[/tex]

We need to find the solutions to the equation g(x)=0. So,

[tex]g(x)=0[/tex]

[tex](5x-1)(x+4)=0[/tex]

Using zero product property, we get

[tex]5x-1=0[/tex] and [tex]x+4=0[/tex]

[tex]x=\dfrac{1}{5}[/tex] and [tex]x=-4[/tex]

Therefore, the solutions to the equation g(x)=0 are [tex]x=\dfrac{1}{5}[/tex] and [tex]x=-4[/tex].

Answer:

SO first we need to get our numbers.

WE see 20.9 and 10.We learned in school that when

you multiply decimals itll show the placr its in.

So it basically shows you the answer.

Now lets divide, 20.9 divided by 10=2.09

Answer:

Step-by-step explanation:

3(x-4)=5         use distributive property

3x-12=5         add 12 to both sides

3x=17             isolate x by dividing both sides by 3

x=5.66 repeating or 5 2/3

[tex]\huge\text{Hey there!}[/tex]

[tex]\mathsf{3(x- 4) = 5}[/tex]

[tex]\large\textsf{DISTRIBUTE 3 within your parentheses}[/tex]

[tex]\mathsf{3(x) + 3(-4) = 5}[/tex]

[tex]\mathsf{3(x) = \bf 3x}[/tex]

[tex]\mathsf{3(-4)=\bf -12}[/tex]

[tex]\large\text{NEW EQUATION: \textsf{3x - 12 = 5}}[/tex]

[tex]\mathsf{3x - 12 = 5}[/tex]

[tex]\large\textsf{ADD 12 to BOTH SIDES}[/tex]

[tex]\mathsf{3x - 12 + 12 = 5+12}[/tex]

[tex]\large\text{CANCEL out: \textsf{-12 + 12} because that gives you \textsf{0}}[/tex]

[tex]\large\text{KEEP: \textsf{5 + 12} because it helps solve for the \textsf{x value}}[/tex]

[tex]\mathsf{5+12=\bf 17}[/tex]

[tex]\large\text{NEW EQUATION: \textsf{3x = 17}}[/tex]

[tex]\mathsf{3x = 17}[/tex]

[tex]\large\textsf{DIVIDE 3 to BOTH SIDES}[/tex]

[tex]\mathsf{\dfrac{3x}{3}=\dfrac{17}{3}}[/tex]

[tex]\large\text{CANCEL out: }\mathsf{\dfrac{3}{3}}\large\text{ because that gives you the value of \textsf{1}}[/tex]

Answer:

The probability that Tara will select a blue marble from each bag is [tex]\frac{2}{27}[/tex].

Step-by-step explanation:

Since there are 15 marbles in the first bag and 9 marbles in the second bag, that means there are a total of 135 different combinations of one marble from each bag. Since there are 5 blue marbles in the first bag and 2 blue marbles in the second bag, there are 10 different possible combinations of one blue marble from each bag. The probability that Tara will select a blue marble from each bag can be represented as [tex]\frac{10}{135}[/tex] or [tex]\frac{2}{27}[/tex].

Answer:

14*6=18 or add them

its either multiply or add them together

Answer:

missing angle = 120 degrees

Step-by-step explanation:

180 -50 -70 =60. 180-60 =120. sorry for brief work but i assume you need it fast

Answer:

20°

Step-by-step explanation:

180-(70+50)=60

180-60=120

dude...it's a straight angle just work it out...laws of exterior and interior angles...

Answer:

-4 and 1, which is (-4,0) and (1,0) in coordinate form

Step-by-step explanation:

the zeros are x-intercepts, and because its a quadratic, there are two x-intercepts, or zeros, so answer is -4 and 1

Answer:

the probability of getting doubles is 1 / 6

I hope this may be helpful

Answer:

it is 1/36

Step-by-step explanation:

if you want to get doubles, you have a chance of 1 out of 6 on each die. All you have to do from here is multiply them

1/6*1/6=1/36

Answer:

[tex]y = - \frac{7}{3} x + 4[/tex]

Step-by-step explanation:

I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.

Answer:

Rs 1400

Step-by-step explanation:

Let us take the required number be x. According to question ,

=> 25% of x = Rs 350

=> 25/100 × x = Rs 350

=> x = Rs 350 × 100 / 25

=> x = Rs 1400

Answer:

it should be d. 315

Step-by-step explanation:

to find the volume, we need to multiply length x width x height. the base is both width and height together, so if we just multiply the base and the height we should get the volume which would be 315 cubic centimeters.

i have not done the test, so please tell me if im incorrect.

Answer:

280/4 = 70 miles per hour. Next, take the unit rate and multiply it by the number of hours you are trying to find. In this case, you are trying to find 6 hours and 30 minutes, but this can also be rewritten as 6.5, since 30 minutes is half an hour. So, in 6.5 hours, the car can go 455 miles
