Answer:

An arrangement of objects, pictures, or numbers in columns and rows is called an array

Answer:

An array is a way to represent multiplication and division using rows and columns. Rows represent the number of groups. Columns represent the number in each group or the size of each group

No picture, nothing to rate here.

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:

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

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:

[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]

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:

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,
