what is 3^9 x 3^5?

Well formatted version of question :

Olga tried to solve an equation step by step

1/4(1/3k+9)=6

step 1- 1/3k+9=24

step 2- 1/3k=15

step 3- k=5

find olgas mistake

step 1

step 2

step 3

olga did not make a mistake

Answer:

Step 3

Step-by-step explanation:

Given the equation :

1/4(1/3k+9)=6

Step 1 : Olga multiplied both sides by 4

1/4(1/3k + 9) * 4 = 6* 4

1/3k + 9 = 24

Step 2 : Olga subtracted 9 from sides

1/3k + 9 - 9 = 24 - 9

1/3k = 15

Step 3 : Both sides should be multiplied by 3

1/3k * 3 = 15 * 3

k = 45

This is the step Olga made a mistake. Olga attempted to divide 15/3 = 5 instead of Multiplying 15 * 3 to obtain 45

Answer:

the answer 4

Step-by-step explanation:

4 of each because (1.25x4) + (1.50x4) = 11.50

Answer:

Sally bought 6 sodas and 2 cups of coffee.

Step-by-step explanation:

Variable x = number of sodas

Variable y = number of coffees

$1.50x + $1.25y = $11.50

x + y = 8 drinks

$1.50(6) + $1.25(2) = $11.50

$9.00 + $2.50 = $11.50

I simply plugged in numbers that totalled to 8 drinks until I reached $11.50 as the total.

For example:

$1.50(5) + $1.25(3) = $11.50

$7.50 + $3.75 = $11.50

$11.25 = $11.50

This is not correct as they do not equal so this cannot be the answer.

Answer: 121°

Step-by-step explanation:

The measure of angle B will be [tex]121^0[/tex] .

Angle is formed by two rays lie in the plane that contains the rays.

We have,

[tex]m \angle A =(6x-19)^0[/tex]

Now,

Linear pair angles are those angles whose sum is [tex]180^0[/tex] .

i.e.

[tex]m \angle A + m \angle B=180^0[/tex]

So,

[tex](6x-19)^0 +(11x-22)^0 =180^0[/tex]

Now,

[tex]17x-41=180[/tex]

[tex]17x=221[/tex]

[tex]x=13[/tex]

So,

[tex]m\angle B=(11x-22)^0[/tex]

Putting value of x;

[tex]m\angle B=(11*13-22)^0[/tex]

[tex]m\angle B=(121)^0[/tex]

So, measure of angle B is [tex]121^0[/tex].

Hence, we can say that the measure of angle B will be [tex]121^0[/tex] .

Answer:

I think C

so it's kind of a process of elimination you have to see the order of the numbers and what order each number is in so for A you can see that it's 345 is greater than 354 which is inspect cuz 354 is greater than 345 for B that's an obvious answer is is 400 is less than 40 which is obviously wrong because 400 is greater has two zeros and 40 only has one 0 for C it has 4008 is less than 4080which is actually correct if you look at the way that the numbers are written you could see that 80 is greater than 8 D it's obviously not correct because it says 20090 is equal to 23009 which is incorrect because 90 is greater than 9

Answer:

x = -4 3/16.

Step-by-step explanation:

First, convert -27/8 to a mixed number. -3 3/8.

So we can take 5 + 2x = -3 3/8 and subtract 5 from both sides (to get rid of the 5 on the left)

The equation turns into this: 2x = -8 3/8.

Now we can divide by 2 on both sides.

The equation becomes x = -4 3/16.

Answer:

-5/2 or -2.5

Step-by-step explanation:

Find the slope using rise over run (y2 - y1) / (x2 - x1)

(y2 - y1) / (x2 - x1)

(33 - 8) / (-16 + 6)

25 / -10

= -5/2

So, the slope is -5/2 or -2.5

Answer:

We know that

Slope

Answer:

tan ∅ = 16/12

Step-by-step explanation:

Once again here are the trigonometric ratios

Sin = Opposite over Hypotenuse

Cos = Adjacent over Hypotenuse

Tan = Opposite over Tangent

We are asked to find tan ∅

Looking at the trigonometric ratios we see that tan = opposite over adjacent

So we find the side length opposite of the indicated angle (∅) which would be 16 then we find the angle adjacent angle ( the side that is not the hypotenuse nor the opposite ) so the adjacent of angle ∅ is 12

so tan ∅ = opposite (16) over adjacent (12)

tan ∅ = 16/12

Answer:

it may be V ≈ 4191.6 cm3 so sorry if i'm wrong!!!

Step-by-step explanation:

Answer: V ≈ 2514.9 cm3

Step-by-step explanation:

To find the volume of the prism, first calculate the area of the base.

To find the apothem of the hexagonal base, recognize that the sum of the measures of the interior angles in a hexagon is (6−2)⋅180°=720°. So, the interior angle has measure 720°6/=120°.

The base angle of the triangles with the hexagon's sides as their base is one-half of 120°, or 60°. The apothem bisects these triangles to form two right triangles with the short leg length of 5.5 cm.

By the definition of tangent, tan 60°=?/5.5.

Solve for ?.

?=5.5 ⋅ tan 60°

Therefore, the apothem length equals 5.5 ⋅ tan 60°.

The area of a hexagonal base.

B=6⋅(12⋅11⋅?)

Substitute 5.5⋅tan60° for ?.

B=6⋅(12⋅11⋅5.5 ⋅ tan60°)

Simplify.

B=181.5 ⋅ tan60° cm2

The volume of a prism.

V=Bh

Substitute 181.5 ⋅ tan60° for B and 8 for h.

V=(181.5 ⋅ tan60°)⋅8

Multiply 181.5 by 8.

V=1452 ⋅ tan60°

Use a calculator to approximate.

V≈2514.9 cm3

Therefore, the volume of the hexagonal prism is approximately 2514.9 cm3.

Answer:

B, C, D

Step-by-step explanation:

7x + 1 + 105 = 180

7x = 74

x = 74/7

4y + 14 + 7y + 1 = 180

11y = 165

y = 15

m<A = 4y + 14 = 4(15) + 14 = 74°

m<B = 7x + 1 = 7(74/7) + 1 = 75°

m<C = 7y + 1 = 7(15) + 1 = 106°

Answer:

The average movie ticket prices in 2020 was $ 10.25.

Step-by-step explanation:

If (0 , 4) and ( 8, 6) are two points on a line, the slope of the line is:

m= y2 - y1/ x2 - x1

m= (6 - 4) / (8 - 0)

m= 1 / 4

The y-intercept is $ 4, meaning it is the average movie ticket price in 1995.

Therefore,

Y = mx + b

Y = 1/4 x + b

It is m= 1/4, interpreting the slope we have that for every additional 4 years the average movie ticket price will increase by $ 1.

The year 2020 is 25 years after 1995, then

Y= 1/4 (25) + 4

Y = $ 10.25

The average movie ticket price was $10.25 in 2020.
