None of the above.

Answer: x = 8/4 = 2

12(2) + 4(6) = 24 + 24 = 48 = 6*8

Step-by-step explanation:

$12X + $6(4) = (X+4)*$8

12X + 24 = 8(x+4)

12x + 24 = 8x + 32

12x + 24 - 8x - 32 = 0

4x - 8 = 0

4x = 8

x = 8/4 = 2

Answer:

1) C=80°

2) A=C= 54°

Step-by-step explanation:

1) 180-60-40=80

2)180-72=108

108/2=54

Hope this helps! :)

Answer:

1. 80º

2. Both are 54º

Step-by-step explanation:

1. If you add 60º + 40º in problem 1, you get 100º. We need to get it to equal 180º, so this means the missing angle would be 80º

2. Just like in the first one, we need this to equal 180º. So, let's go backwards.

180 - 72 = 108

Now, since the remaining angles are equal, let's divide 108º by 2

108 / 2 = 54º

Hope this helps :)

Answer:

80%

Step-by-step explanation:

24 devided by 30 = 0.8

0.8 times 100 = 80%

Answer:

80%

Step-by-step explanation:

take the number you got  and divide it by how many it was out of and then move the decimal two points to the right. 24/30= 0.8     then move the decimal and get 80 and add the percent sign.

Answer:

The function describes the motorboat's distance from the shore  

Step-by-step explanation:

A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore

After 9 minutes, it is 14 km from the shore.

So, rate of change =  

Negative sign shows that there is decrease in distance per minute

The rate of change of distance is 4 km / minutes

General equation : y = mx+c

Where m is the slope and c is the constant

Substitute the values in the equation :

y=-4x+50

Where y is the final distance and x is the minutes

So, Option C is true

Hence The function describes the motorboat's distance from the shore

Answer:

I would need to know the number of radios she made each day.

Step-by-step explanation:

lets say she assembled 2 radios a day, which means we would do 0.54 x 2 (that would be 1.08) and then times it by 6 ***not incuding sunday***

you would get $6.48

then for sunday we would do 0.62 x 2 (that would be 1.24) .

now we add 6.48 and 1.24 to get $7.72 a week.

Answer:70/100 or 7/10

Step-by-step explanation:

one hour is 60 mins

1/5 of an hour is 12 mins

1/2 of an hour is 30

30 + 12 = 42

42/60 simplified is 7/10

Answer:

8

Step-by-step explanation:

Given:

Total money Jervane can spend = $20.

Cost of a coffee = $3.

Cost of a donut = $2.

To find: Maximum number of donuts Jervane can buy.

Solution:

Let the number of donuts she can buy be [tex]x[/tex].

She wants to spend no more than $20 in total.

So,

[tex]3+2x\leq 20[/tex]

[tex]\Rightarrow 2x\leqslant 20-3[/tex]

[tex]\Rightarrow 2x\leqslant 17[/tex]

[tex]\Rightarrow x\leqslant \frac{17}{2}[/tex]

[tex]\Rightarrow x\leqslant 8 \frac{1}{2}[/tex]

As the number of donuts can only be a natural number.

Hence, the maximum number of donuts that Jervane can buy are 8.

Step-by-step explanation:

16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)

C (2,-3) D (6,3)

CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)

CD = sqaureroot of ( 16 + 36)

CD = sqaureroot of 52 = 2 root 13 = length

17. E (5, - 1) because the point is under the x axis.

Midpoint = ((x1+ x0)/2 , (y1 +y0) /2)

B (8,1) C (2, - 3)

Midpoint of BC = ((2+8)/2 , (-3+1)/2)

= (10/2 , - 2/2)

= (5, - 1)

18. Length of AE

A (4,5) E(5,-1)

Answer:

Step-by-step explanation:

What is the value of 1 − 2sin^2(105°)?

Given the expression

1 − 2sin²(105°)

= 1 - 2(sin105)²

= 1 - 2(0.9659)²

= 1 - 2(0.9330)

= 1 - 1.8660

= 0.8660

0.8660 can also be expressed as √3/2

Hence  1 − 2sin²(105°) is  √3/2

Answer:

3.25 degrees/hour

Step-by-step explanation:

Last night, the temperature fell from 0°F to -13°F in 4 hour.

We need to find the average temperature change per hour. It can be calculated by dividing the change in temperature per unit time.

Change in temperature = -13°F -0°F = -13°F

So,

[tex]C=\dfrac{-13}{4}\\\\=-3.25\ \text{degrees/hour}[/tex]

So, the change in temperature is 3.25 degrees/hour.

Answer:

-3.25 degrees an hour

Step-by-step explanation:

-13 ÷ 4 = -3.25

The answer is 7 or 7.07. Hope this helps

z = 106

y = 74

Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.
