Answer:

OPTION 1

Step-by-step explanation:

all the marked values are less than six, just as in the inequality. We did not choose option 4 because we're not dealing with '≥'

The answer is option 1!!!!!!!!?!

Answer:

x =4

Step-by-step explanation:

so pretty much you're give the values for theta and phi, so all you have to do is insert the values in their corresponding position and simplify it. After the simplification process, the answer should be no less or more than 4.

Answer:

the answer is 4

Step-by-step explanation:

by simplification;

Step-by-step explanation:

x + 62 = 90

because they are complementary angles

I don't see any r

but I guess since they're complementary it would be 90 - 62

Answer:

Complementary angles

x = 28°

Step-by-step explanation:

Angle relationship = Complementary angles

x = 90° - 62° = 28°

Answer:

x=5

y=-17

Step-by-step explanation:

basically what I did was:

1) I multiplied the first equation by 4 , solved for x

2) I used the value of x that i found and substituted in one of the equations to find y

Answer: x=0 y=2

Answer:

$511.575

Step-by-step explanation:

Given data

P=$475

R=3.8%

T= 2 years

Compound interest

A=P(1+r)^t

substitute

A=475(1+0.038)^2

A=475(1.038)^2

A=475*1.077

A=511.575

Hence the final amount is $511.575

Answer:

volume of sphere=4/3 π4³=256/3π ft²

Answer:

y=1

x=-7

Step-by-step explanation:

x+y=-6    x=-6-y

x+5y=-2

substitute

(-6-y)+5y=-2

reduce

-6+4y=-2

4y=4

y=1

x=-6-y=-6-1=-7

Answer:

1. x+y=−6

Find the x-intercepts.

x-intercept(s):

(−6,0)

Find the y-intercepts.

Tap for more steps...

y-intercept(s):

(0,−6)

List the intersections.

x-intercept(s):

(−6,0)

y-intercept(s):

(0,−6)

2. To find the x-intercept, substitute in

0 for y and solve for x. To find the y-intercept, substitute in

0 for x and solve for y.

x-intercept(s):

(−2,0)

y-intercept(s):

(0,−2/5)

x+5y=−2

Subtract x from both sides of the equation.

5y=−2−x

Divide each term by 5 and simplify.

y=−2/5−x5

Subtract 5y from both sides of the equation.

x=−2−5y

Answer:

5/12

Step-by-step explanation:

Total distance travelled = 30% + 1/4

To add these numbers, convert 30% to fraction

30% = 1/3

1/3 + 1/4 = 7/12

Remaining distance = 1 - 7/12 = 5/12

Answer:

The answer is

[tex]x = 12 \\ y = 20 \\ z = 15[/tex]

Step-by-step explanation:

By using Pythagoras low

Then we can find that

[tex] {y}^{2} = {x}^{2} + {16}^{2} \\ {z}^{2} = {x}^{2} + {9}^{2} \\ {y}^{2} + {z}^{2} = {25}^{2} \\ then \\ {x}^{2} + {9}^{2} + {x}^{2} + {16}^{2} = {25}^{2} \\ 2 {x}^{2} = 288 \\ x = 12 \\ By \: substituting \: x \: into \: the \: previous \: equations \\ then \: \\ y = 20 \\ z = 15[/tex]

Answer:

m∡QPR = 25°

Step-by-step explanation:

solve for 'x':

8x + 7 + 9x + 16 = 40

17x + 23 = 40

17x = 17

x = 1

m∡QPR = 9(1) + 16

m∡QPR = 25°

Answer:

first question: decrease - second question: 34

Step-by-step explanation:

first question: to find the mean, you need to add all of the numbers together and divide the sum of those by the amount of numbers you added together. in this question, it would be

73+79+96+84=332 -> 332/4=83 is the mean for the 1st set of numbers

(1)   (2)  (3)   (4)

the question asks what happens after the next test score is added in, for this, you will do the same steps as before except you add in the 80 for her fifth test and then divide by 5 instead of 4, because you have another number being added.

73+79+96+84+80=412 -> 412/5=82.4 is the mean for the 2nd set of numbers

the second set of numbers, after the fifth test score is added in, is lower than the first set of numbers. therefore, the mean decreases

second question: same concept, except on a dot plot. a dot above a number means that there is one of those numbers that should be counted. this means since there are 2 dots above the 30, there are 2 30s being added to the rest of the numbers. in this dot plot, the numbers being added are

30+30+32+32+34+38+38+38=272 -> 272/8=34 is the mean

hope this helps!

Answer:

10 3/4, 4 3/4, and 9 1/2

Step-by-step explanation:

We're going to let x represent the length of the longest side. The perimeter is

x +(x-6) +2(x-6) = 25

4x -18 = 25

4x = 43

x = 43/4 = 10 3/4

Then x-6 = 4 3/4.

Multiply that two to get 8 3/2 = 9 1/2

I hope this helped! :)

Step-by-step explanation:

Given:

The midpoint of overline AB is M(0, - 7) .

The coordinates of A are (- 2, - 6).

To find:

The coordinates of point B.

Solution:

Let the coordinates of point B are (a,b).

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

The midpoint of overline AB is M(0, - 7). Using the midpoint formula, we get

[tex]M=\left(\dfrac{-2+a}{2},\dfrac{-6+b}{2}\right)[/tex]

[tex](0,-7)=\left(\dfrac{-2+a}{2},\dfrac{-6+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{-2+a}{2}=0[/tex]

[tex]-2+a=0[/tex]

[tex]a=2[/tex]

And,

[tex]\dfrac{-6+b}{2}=-7[/tex]

[tex]-6+b=-14[/tex]

[tex]b=-14+6[/tex]

[tex]b=-8[/tex]

Therefore, the coordinates of point B are (2,-8).

Answer:

yep

Step-by-step explanation:

when you divide a fraction u can use the KCF method which is basically:

(keep) the first fraction the same

(change) the division sign in the middle to a multiplication sign

(flip) the second fraction

basically because you have to flip the 1/4 when you divide it, it'll be the same as a 4/1 anyways

As there are multiple answers going with trial and error seems good in this case.

A

5.00 + 5.00 + 5.00 + 5.00 = 20.00

3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 31.5

20.00 + 31.5 = 51.5

B

5.00 + 5.00 + 5.00 + 5.00 = 20.00

3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 35.00

20.00 + 35.00 = 55.00

C

5.00 + 5.00 + 5.00 = 15.00

3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 31.5

15.00 + 31.5 =46.5

Knowing that for the first one all A,B, and C were wrong we can determine that D is the answer. But wait if I made one mistake and didn't understand if $156.5 is equivalent to $156.50 that would mean A is correct.

Always recheck your answers and good luck,

Jon
