Hello the required image is missing attached below is the missing box

answer : FHGE

Step-by-step explanation:

The plane representing the top surface of the box is FHGE. there are still other planes there but do not represent the entire top surface of the Box and they are : FGE, HGE, FHG and FHE. This is because a plane can be represented by three to four Noncollinear points on a solid like a box.

Supplementary angles are angles that add up to 180 degrees.

m<3 + m<4 = 180 degrees

116 + m<4 = 180 degrees.

Subtract 116 from both sides.

m<4 = 64 degrees

The value of ∠4 will be 64°.

It is given that ∠3 and ∠4 are two supplementary angles.

We have to find out the value of ∠4 , if ∠3 = 116 °.

What are the supplementary angles ?

Supplementary angles are angles that add up to 180 degrees.

As per the question ;

∠3 and ∠4 are supplementary angles.

We know that sum of supplementary angles is 180° .

⇒ ∠3 + ∠4 = 180°

given ; ∠3 = 116°

⇒ 116° + ∠4 = 180°

⇒ ∠4 = 180° - 116°

⇒ ∠4 = 64°

Thus , the value of ∠4 will be 64°.

Answer: 9 miles

Step-by-step explanation:

The distance would be 9 because if the speed walker walked 4.5 miles in 3/4  of an hour, he would be going 6 mph (miles per hour).

If he walks twice as fast, he would be going 12 mph.

If he walks for 3/4 of an hour (45 minutes) at 12 mph, he would walk 9 miles.

9 miles he walks in 3/4 hours if he walks twice as fast.

Speed is characterized as the pace of progress of the position of an item toward any path. Speed is estimated as the balance of length to the time in which the distance was covered. Speed is a scalar amount as it has just course and no size.

4 1/2 miles will be covered by him in  3/4 hour

if the speed walker covered 4.5 miles in just over an hour 

The duration would indeed be 9 since the speed walker might be moving at a rate of six miles per hour.

He would be moving at 12 miles per hour if he walked twice as quickly.

He would cover 9 miles in 3/4 of an hour (45 minutes) of walking at a speed of 12 miles per hour.

Answer:

x=4

Step-by-step explanation:

Add 4 to both sides.

12x=5x+24+4

Simplify  5x+24+4 to  5x+28

Subtract 5x from both sides

12x-5x=28

Simplify  12x-5x1 to 7x

7x=28

Divide both sides by 7

28/7

simplify 28/7

x=4

Answer:

4

Step-by-step explanation:

12x - 4 = 5x + 24 convert like terms to the same side of equation

12x - 5x = 24 + 4 as you can see, when we send a terms to the other side of equation its sign changes

7x = 28 multiply both sides by 7

x = 4

Answer:

His actual score is 15

Step-by-step explanation:

Here, we are interested in calculating Wayne’s actual score on the ACT

when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.

Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.

The formula for the z-score or standard score is given below;

z-score = (x - mean)/SD

where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6

So, substituting these values into the z-score equation, we have;

-0.5 = (x-18)/6

x-18 = 6(-0.5)

x -18 = -3

x = -3 + 18

x = 15

Answer:

Step-by-step explanation:

n+(n+2)+(n+4)+(n+6)+(n+8)+(n+10)+(n+12)=217

7n+42=217

7n=175

n=25

25+27+29+31+33+35+37=217

Answer:

25

Step-by-step explanation:

Let the smallest odd integer be n.

The integers are: n, n + 2, n + 4, n + 6, n + 8, n + 10, n + 12

Their sum is 217.

n + n + 2 + n + 4 + n + 6 + n + 8 + n + 10 + n + 12 = 217

7n + 42 = 217

7n = 175

n = 25

x = 10

Step-by-step explanation:

[tex]3 - \frac{3}{4}x = \frac{1}{4}x - 7[/tex]

Start by subtracting 3 to both sides

[tex]-\frac{3}{4}x = \frac{1}{4}x-10[/tex]

Subtract 1/4x from both sides ( -3/4 - 1/4 ) = - 1

[tex]-x = -10[/tex]

Divide both sides by a negativ 1 to get rid of the negative

∴  [tex]x = 10[/tex]

Answer:

[tex]\huge\boxed{-6}[/tex]

Step-by-step explanation:

Since we know the values of a, b, and c, we can substitute them into our expression and get the value.

[tex]-2b + | -3c + a |\\\\-2(6) + |-3(-3) + -3 |[/tex]

A negative multiplied by a negative gets us a positive.

[tex]-2(6) + |9 + -3 |[/tex]

Adding a negative is the same as subtracting a positive.

[tex]-2(6) + |9 -3 |\\-2(6) + 6[/tex]

[tex]-2 \cdot 6 = -12\\\\-12+6\\\\-6[/tex]

Hope this helps.

The simplified form of the expression will be 7-9.8g.

A mathematical expression is a sentence that has at least two variables or integers and one mathematical action. In mathematics, it is possible to multiply, divide, add, or subtract. The construction of an expression is as follows: Expression, number, and mathematical operator.

It is given that the expression is,-1.4(-5+7g

We have to simplify the expression​.

Suppose the simplified value of the expression is x,

x= -1.4(-5+7g)

x= -1.4(-5)-1.4(7g)

x=7-9.8g

Thus the simplification of the expression will be 7-9.8g.

[tex]Explanation:[/tex]

[tex]\frac{1}{2}x+\frac{1}{3}x=10[/tex]

1/2x + 1/3x = 10 Simplify both sides

(1/2x + 1/3x) = 10 Combine like terms

5/6 x = 10

(6/5) * (5/6x) = (6/5) * (10) Multiply both sides by 6/5.

x = 12
