Answer:

You need to do 7 time 8 times 2 times 3

Answer:

8

Step-by-step explanation:

Lines have angles that are equal to 180. Therefore, because we already have 140 of the 180 necessary, we can subtract 140 from 180 to get 40. 40 divided by 5 is 8.

Hope that this helps!

Answer:

I. x=8

Step-by-step explanation:

lines form 180° angles so

140 +5x= 180 ; subtract 140 from both sides

5x= 180-140; divide both sides by 5

x= 40/5 = 8

Answer:

x = 5, and/or x= - 7/3

Step-by-step explanation:

|x+1|=|2x+6|

We know eitherx+1=2x+6orx+1=−(2x+6)

x+1=2x+6(Possibility 1)

x+1−2x=2x+6−2x(Subtract 2x from both sides)

−x+1=6

−x+1−1=6−1 (Subtract 1 from both sides)

−x=5

(Divide both sides by -1)

x=−5

x+1=−(2x+6)(Possibility 2)

x+1=−2x−6(Simplify both sides of the equation)

x+1+2x=−2x−6+2x(Add 2x to both sides)

3x+1=−6

3x+1−1=−6−1(Subtract 1 from both sides)

3x=−7

Divide both sides by 3

x= −7 / 3

Check answers. (Plug them in to make sure they work.)

x=−5(Works in original equation)

x= −7/3

(Works in original equation)

Answer:

x=−5 or x= −7 / 3

Answer: 3.5 - 4.4 pounds

Step-by-step explanation:

You included no options so I answered with the range of the answer.

When rounding a number up to the nearest whole number, the number needs to have the first decimal being 0.5 and above all the way to 0.9.

When rounding a number down to the nearest whole number, the number needs to have its first decimal being 0.1 to 0.4 to be rounded down.

For instance, 3.5 to 3.9 would get rounded up to 4 pounds.

4.1 to 4.4 would be rounded down to 4 pounds.

To solve this problem, we simply need to plot the cosine graph.

The graph of cosine can easily be plotted and we can compare both together.

⇻Option B. x - 2 is the correct answer.

Answer:

C

Step-by-step explanation:

Using Pythagoras' identity in right triangle BPO

with PB = 4 ( half of AB ) and OB = 5 ( radius of circle )

OP² + 4² = 5²

OP² + 16 = 25 ( subtract 16 from both sides )

OP² = 9 ( take the square root of both sides )

OP = [tex]\sqrt{9}[/tex] = 3

8mm×10mm

450mm-80mm =370mm

Using exponential function concepts, it is found that the change of the growth factor of the population each half hour is given by:

b. [tex]\sqrt{\frac{1}{6}}[/tex]

e. [tex]\left(\frac{1}{6}\right)^{0.5}[/tex]

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

In this problem, the growth factor of 1/6 each hour, hence, [tex]r = \frac{1}{6}[/tex], and:

[tex]A(t) = A(0)(1 + \frac{1}{6})^t[/tex]

For each half-hour, t = 0.5, hence the growth factor is of:

[tex]\left(\frac{1}{6}\right)^{0.5} = \sqrt{\frac{1}{6}}[/tex]

Hence, options b and e are correct.

Answer:

(E) 72 w^2 is the answer

Step-by-step explanation:

outer square area is 81 w^2

inner square area is 9 w^2

subtracting outer - inner we can get the shaded area

so 81 -9= 72w^2

Answer:

E. 72w²

Step-by-step explain:

= 9w × 9w

= 81w²

= 3w × 3w

= 9w²

= 81w² - 9w²

= 72w²

Answer:

Step-by-step explanation:

M1 for ( ) 42/7 [x(7+3+5)] soi by 6

=90

Assuming there are only 42 yellow balls in the bag. The total number of balls in the bag is 90 balls.

Formulate

42×(3+5+7)÷7

Reduce the fraction

42÷7×(3+5+7)

6×(3+5+7)

Hence:

Total number of balls=6×15

Total number of balls=90 balls

Inconclusion the total number of balls in the bag is 90 balls.

Answer:

The answer is Zero

Step-by-step explanation:

So you always do what is in the parentheses first no matter what so in this case you would do 8 - 2 which is 6 then you would do the rest of the equation in order so that means if there were multiplication and division and multiplication came second do division first don't just do the multiplication so any way you got the answer 6 and the next step is to subtract 6 from the answer you just got so now your equation is 6 - 6 which is zero hope this helps plz mark me as brainliest

Answer:

2 is the answer

Step-by-step explanation:

Answer:

AB = 21

Step-by-step explanation:

Since B is the midpoint of AC , then

BC = AB

2x - 11 = x + 5 ( subtract x from both sides )

x - 11 = 5 ( add 11 to both sides )

x = 16

Then

AB = x + 5 = 16 + 5 = 21

Step-by-step explanation:

The general vertex form is given by

[tex]y = a {(x - h)}^{2} + k[/tex]

where (h, k) is the vertex and a is a constant. So we can write the y as

[tex]y = a {(x - 2)}^{2} + 1[/tex]

To find the value of a, substitute the point (1, -4)

-4 = a(1 - 2)^2 + 1

or a = -5

Therefore, the vertex form of the parabola is

[tex]y = - 5 {(x - 2)}^{2} + 1[/tex]

Answer:

B. 27 square units

Step-by-step explanation:

Area of ∆LMN = ½(base*height)

base = MN = 6 units

height = distance from L to MN = 9 units

Plug in the values into the formula

Area of ∆LMN = ½(6*9)

Area = ½(54)

Area = 27 square units
