Answer: 718.38

Step-by-step explanation:

Answer:

-⅖

Step-by-step explanation:

We need to simplify the given equation and find out the value of a , as ,

=> 3(a-1)+31-11a = 4(2a+3)

=> 3a -3+31-11a = 8a + 12

=> -8a -28 = 8a + 12

=> 16a = -28-12

=> 16a = -40

=> a = -2/5

3 ( a - 1 ) + 31 - 11a = 4 ( 2a + 3 )

⇒ 3 ( a - 1 ) + 31 - 11a = 4 ( 2a + 3 )

Opening the brackets and multiplying the terms, We get,

⇒ 3a - 3 + 31 - 11a = 8a + 12

⇒ -8a + 28 = 8a + 12

⇒ 8a + 8a = - 28 - 12

⇒ 16a = 40

Transposing 16 to Right Hand Side, We get,

⇒ a = [tex] \sf \frac{40}{16} [/tex]

⇒ a = [tex] \sf \frac{-2}{5} [/tex]

Answer:

4w^2 +4w+1

this is the product.

Step-by-step explanation:

Answer:

4w^2+4w+1 is very correct

Step-by-step explanation:

so I just wanted to explain more

so you expand the question like this

(2w+1)(2w+1) then

further expand by 2w(2w+1)+1(2w+1) so you use what was in the first bracket to multiply the second bracket

then it will be 2w×2w= 4w^2 that how I got that part so you multiply what's in the bracket by what is outside of it = 4w^2 +2w+2w+1 = 4w^2 +4w not 4w^2 because it's not multiplication +1

Answer:

28 and 30

Step-by-step explanation:

'x' = 1st consecutive #

'x+2' = 2nd consecutive #

x + x+2 = 58

2x + 2 = 58

2x = 56

x = 28

x+2 = 30

Answer:

0.108

Step-by-step explanation:

Using the poisson probability process :

Where :

P(x =x) = (e^-λ * λ^x) ÷ x!

Given that :

Each batch of bread = 3 loaves

Each loaf = 15 slices

Total slice per batch = 15 * 3 = 45 slices

Number of raising added = 100

Average number of raisin per slice, λ = 100/45 = 20/9

Hence,

Probability that a randomly chosen slice has no raising :

P(x = 0) = (e^-λ * λ^x) ÷ x!

P(x = 0) = (e^-(100/45) * (100/45)^0) ÷ 0!

P(x = 0) = (0.1083680 * 1) / 1

P(x = 0) = 0.108

Answer:

[tex]x = 73.74[/tex]°.

Step-by-step explanation:

In order to find the angle measure of [tex]x[/tex], you can use the trigonometric function sine to calculate the value of it. Sine is a trigonometric function used in right triangles to solve for the sides and angles, it states that the sine of an angle is equal to the side opposite to it divided by the hypotenuse. In this case, [tex]sin(x)=\frac{48}{50}[/tex]. If you want to isolate the variable [tex]x[/tex] on one side to calculate its value, take the [tex]sin^{-1}[/tex] or arcsine of both sides. [tex]arcsin(sin(x))=arcsin(\frac{48}{50})[/tex] ⇒ [tex]x = arcsin(\frac{48}{50})[/tex] ⇒ [tex]x[/tex] ≈ 73.74°, so that would be the correct answer.

Answer:

[tex]9.35 \le M \le 9.45[/tex]

Step-by-step explanation:

Given

[tex]M = 9.4[/tex] to 1 d p

Required

The error interval

The error interval is represented as:

[tex]Lower \le M \le Upper[/tex]

Where

[tex]Lower = M - 0.05[/tex]

[tex]Upper = M + 0.05[/tex]

So, we have:

[tex]Lower = M - 0.05[/tex]

[tex]Lower = 9.4 - 0.05[/tex]

[tex]Lower = 9.35[/tex]

[tex]Upper = M + 0.05[/tex]

[tex]Upper = 9.4 + 0.05[/tex]

[tex]Upper = 9.45[/tex]

Hence, the error interval: [tex]Lower \le M \le Upper[/tex] is:

[tex]9.35 \le M \le 9.45[/tex]

[tex]Area = 3[/tex]

Step-by-step explanation:

Given

[tex]D = (-4,-4)[/tex]

[tex]E = (-2,-4)[/tex]

[tex]F = (-3,-1)[/tex]

Solving (a) and (b):

See attachment for plot and labelled vertices

Solving (c): The area

This is calculated using:

[tex]Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2+x_3y_1 - x_1y_3|[/tex]

Where:

[tex]D = (-4,-4)[/tex] -- [tex](x_1,y_1)[/tex]

[tex]E = (-2,-4)[/tex]  -- [tex](x_2,y_2)[/tex]

[tex]F = (-3,-1)[/tex] -- [tex](x_3,y_3)[/tex]

This gives:

[tex]Area = \frac{1}{2}|(-4*-4) - (-4*-2) + (-2 *-1) - (-3*-4)+(-3*-4) - (-4*-1)|[/tex]

[tex]Area = \frac{1}{2}|16 - 8 +2- 12+12 - 4|[/tex]

[tex]Area = \frac{1}{2}|6|[/tex]

This gives

[tex]Area = \frac{1}{2} * 6[/tex]

[tex]Area = 3[/tex]

Step-by-step explanation:

Answer:

7.5 - 3.8 = m

Step-by-step explanation:

The equation can be used to determine the number of miles (m) Lexi has left to hike will be m + 3.8 = 7.5.

It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.

Lexi is hiking a trail that is 7.5 miles long. She stops to take a break after hiking 3.8 miles of the trail.

Then the equation can be used to determine the number of miles (m) Lexi has left to hike will be

Let m be the number of miles left. Then we have

m + 3.8 = 7.5

Subtract 3.8 on both sides, then we have

m = 3.7

I think it is 34,560

Step-by-step explanation:

3 x 12 x 2 x 6 x 10 x 8 = 34,560

The surface area of the given figure is 394 square cm.

Surface area refers to the total area that the surface of a three-dimensional object occupies. It is the sum of the areas of all the faces or surfaces of the object. Surface area is usually measured in square units, such as square meters (m²) or square feet (ft²).

The surface area will be calculated by calculating the area of each face and then adding all the areas,

SA = 2 ( 2 x 12 ) + 2 ( 2 x 10 ) + ( 8 x 6 ) + 2 ( 3 x 8 ) + ( 3 x 6 ) + ( 12 x 16 )

SA = 48 + 40 + 48 + 48 + 18 + 192

SA = 394 square cm.

Therefore, the surface area of the figure will be 394 square cm.
