Answer:

Step-by-step explanation:

So, first we can do 14/4 which is 3.5

Each class uses 3.5 gallons

For (B), we can do 3.5 * 3 which equals 10.5 gallons

For (C), we can do 30÷4 which is 7.5 square feet

For (D) they each paint 1/4 of the wall

Answer:

D.

Answer:

y= 4/3x -1/3

Step-by-step explanation:

Find slope: y2-y1/x2-x1 = 5-(-3)/4-(-2) = 8/6 = 4/3

Use point slope to find the equation:

y - y1 = m ( x - x1 )

y - (-3) = 4/3 ( x - (-2))

y = 4/3x + 8/3 + (-3)

y = 4/3x + 8/3 - 9/3

y= 4/3x -1/3

Answer:

SAS(Side.Angle.Side

Step-by-step explanation:

since x is mid point of pr and qs so px=xr and x is midpoint of qs so qx=sx,

and two lines intercept so angles made on point x are equal.....hence 2 sides and one angle proved so triangles are equal

The postulate that can be used to prove that triangle QXP and triangle SXR are congruent to each other is: SAS Congruence Theorem,

Recall:

Since X is a midpoint of QS and RP, therefore:

[tex]PX \cong RX\\\\QX \cong SX\\[/tex]

<PXQ = <SXR (vertical angles are congruent)

Therefore, the postulate that can be used to prove that triangle QXP and triangle SXR are congruent to each other is: SAS Congruence Theorem,

Here's something to help you

Step-by-step explanation:

I'm using the second question as an example.

To find the Unit Rate, you have to divide the amount of money by the amount of whatever the product is

5.99/8= 0.74875

Since the question says to round it to the nearest hundredth, that means the price per unit (unit rate, or the price for one battery here) would be about $0.75. Simple, right?

Answer:

360 degrees

Step-by-step explanation:

The sum of exterior angles of a heptagon is 360 degrees. For regular heptagon, the measure of the interior angle is about 128.57 degrees. The measure of the central angle of a regular heptagon is approximately 51.43 degrees. The number of diagonals in a heptagon is 14.

Step-by-step explanation:

heptagon = 7

(interior angle)

(7-2)×180 = 900

all 7 vertices angle - interior angle

(7×360) - 900 = 1620

Step-by-step explanation:

The angle of rotation to map A into C is 180°.

The rotation is around the center of the square. Let's assume that the center coincides with the origin of a coordinate axis.

Then we would have A on the second quadrant and C on the fourth quadrant.

Then we need to apply a rotation of two quadrants, remember that each quadrant has an angle of 90°, then a rotation of two quadrants has an angle of 2*90° = 180°.

The correct option is 180°.

Answer:

The ans would be 291 (however we can round this off to 290 as no can partially vote as 0.1)

Step-by-step explanation:

We can easily find the loser's vote by-

70% of 969= 678.9

now, all we need to do is find the winners vote

we know that the total no. of votes= 969 & we know the no. of votes loser got

so, subtracting the losers vote from 969 would give us the remaining no. of votes (the winner's votes)....so,

969-678.9=290.1

we can round this off to 290

Answer:

1/21

Step-by-step explanation:

Changing operations to eliminate negative numerators the equation becomes

=1/3−2/7

With unlike denominators find the Least Common Denominator (LCD)

LCD = 21

Multiplying numerators and denominators to get the LCD in all fraction denominators

=1×7/3×7  −2×3 /7×3

Then rewriting the equation with the equivalent fractions

=7/21−6/21

With like denominators we can operate on just the numerators

=7−6/21

=1/21

[tex] 1\frac{1}{6} [/tex]

Step-by-step explanation:

Given:

[tex] \frac{2}{3}*1\frac{3}{4} [/tex]

Required:

Evaluate

SOLUTION:

To evaluate, we need to convert the mixed fraction to improper fraction, then multiply both fractions together.

Thus:

[tex] \frac{2}{3}*\frac{7}{4} [/tex]

Multiply the numerators together, and multiply the denominators together

[tex] = \frac{2 \times 7}{3 \times 4} [/tex]

[tex] = \frac{14}{12} [/tex]

Simply the fraction by dividing the numerator and denominator by 2

[tex] = \frac{7}{6} [/tex]

[tex] = 1\frac{1}{6} [/tex]

Step-by-step explanation:

Subtract the unwanted terms on the left from both sides.

  (-7x² +6x -16) + M = 6x +5

  M = 6x +5 -(-7x² +6x -16)

  M = 7x² +21 . . . . simplify
