$140 was the original price.

discount : 45%

45% ⇒ $63

1% ⇒ $(63/45)

1% ⇒ $1.4

original price is always 100%

100% ⇒ $(1.4*100)

100% ⇒ $140

Since the two horizontal lines are parallel, 4x+7=75

4x=68

x=17 or 17º

Answer:

x = 17

Step-by-step explanation:

(4x + 7) must equal 75

75 - 7

= 68

4x = 68

4x/4 = 68 /4

x = 68/4

x = 17

The student council sold long sleeve shirts for $12.50 and short sleeve shirts for $10.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the cost of long sleeve and y represent the cost of short sleeve, hence:

24x + 18y = 480     (1)

Also:

34x + 25y = 675    (2)

From both equations:

x = 12.5, y = 10

The cost of long sleeve shirts was $12.50 while short sleeve was $10 each.

y=8x

Answer:

y = -x + 9

Step-by-step explanation:

the equation of a line is given by y = mx + b where m Is the slope and b is the y intercept.

as shown in the graph, the y intercept is 9.

how to find the slope:

the slope is rise over run and as we can see that the points move down once and to the right once at every exact point. hence, the slope is -1.

the equation: y = -x +9

Answer:

The last table.

Step-by-step explanation:

We can see that the last table is the only table that has y values that go up by the same value each time. If x goes up by 1, y goes up by 5. Therefore, the last table is the only table that represents a linear function.

Step-by-step explanation:

Formula

The formula for perimeter is

P = 2L + 2w

Givens

Let the width = w

Length = 3w + 4

P = 80 cm

Solution

P = 2L + 2w

80 = 2(3w + 4) + 2w          Remove the brackets

80 = 6w + 8 + 2w              Combine

80 = 8w + 8                        Subtract 8 from both sides

80-8 = 8w + 8-8                 Combine

72 = 8w                               Divide both sides by 8

72/8 = 8w'8

9 = w

Answer

w = 9

L = 3*w + 4

L = 3*9 + 4

L = 31

Long division helps in breaking the division problem into a sequence of easier steps. Just like all division problems, a large number, which is the dividend, is divided by another number, which is called the divisor, to give a result called the quotient and sometimes a remainder.

Answer:

C = 8π

Area = 32π

Step-by-step explanation:

Radius = 4 cm

Circle Circumference Formula: 2πr

C = 2π*4 = 8π cm

Area Circle Formula: 2πr^2
Area = 2π*4^2 = 2π*4*4 = 2π*16 = 32π cm

The correct statement is A that is The average size of an eighth-grade class is smaller and varies less than that of a seventh-grade class.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations.

The mean of the seventh grade is given as 33.

The mean of the eighth grade is given as 30.

The correct statement is A because the mean absolute deviation of an eighth-grade class is less than that of a seventh-grade class.

Also, the class size is larger on average for seventh-grade classes (33 > 30).

Answer:

Radius = 2.8

Step-by-step explanation:

V = 1⁄3 πr² × h

50 = 1⁄3 πr² × 6

50 = 1⁄3 × 22⁄7 × r² × 6

50 = 22⁄21 × r² × 6

50 = 22⁄21 × 6 × r²

50 = 6.286 × r²

50 = 6.286r²

50/6.286 = 6.286r²/6.286

r² = 7.954

r = √7.954

Answer:

They'll meet after 200 meters , if they simultaneously start running towards each other.

Step-by-step explanation:

Let x =distance travelled by dog and 200-x be the distance travelled by cat. Inorder to meet, the sum of their travelled distances shall be equal to 200 meters as they are far apart by 200 meters.

Dog: Distance =Speed x time: x=30t

Cat: Distance = 200-x

=24t

The sum of their distance travelled shall be 200 meters: 30t+ 24t= 200;54t=200;t=200/54=3.7secs

So they will meet after 3.7 seconds

To check:

Distance travelled by dog :x=30(3.7)

=111.11 meters

Distance travelled by cat: 24t=24(3.7)

=88.89 meters

Therefore since they are travelling towards each other and their distance apart is 200 meters, after 3.7 seconds they will meet because dog travelled 111.11 meters and cat travelled 88.89 meters and they covered already 200 meters as the sum of 111.11+ 88.89

=200 meters
