Answer:

A

Step-by-step explanation:

We assume the opposite and then get to a point where we get a false statement. That proves that the the opposite of the opposite (What we originally wanted to prove) is true.

Answer:

470 cm³

Step-by-step explanation:

Decompose the prism into two rectangular prism.

Prism 1 will have the following dimensions and volume:

Length = 10 cm

Height = 8 cm

Width = 9 - 5 = 4 cm

Volume = L × W × H

Volume = 10 × 8 × 4 = 320 cm³

Prism 2:

Length = 10 cm

Height = 3 cm

Width = 5 cm

Volume = 10 × 3 × 5 = 150 cm³

✔️Volume of the entire prism = 320 + 150 = 470 cm³

Answer:

169 farmers raised chickens last year.

Step-by-step explanation:

Given that:

Number of farmers raising chickens this year = 220

This is 30% more than previous year.

Let,

100% be the percent of previous year and x be the number of farmers who raised chicken previous year.

Percent of farmers who raised chickens this year = (100+30)% = 130%

130% of x = 220

[tex]\frac{130}{100}x = 220[/tex]

1.3x = 220

Dividing both sides by 1.3

[tex]\frac{1.3x}{1.3}=\frac{220}{1.3}\\x=169.23[/tex]

Rounding to nearest whole number

x = 169

Hence,

169 farmers raised chickens last year.

Step-by-step explanation:

We need to input the values of "a" into the equation.

1) 3 x 2 + 1

So 3 x 2 = 6 and plus one is 7.

Answer:

Quadrant IV

Step-by-step explanation:

For an angle in the fourth quadrant the point P has positive x coordinate and negative y coordinate. Therefore: In Quadrant IV, cos(θ) > 0, sin(θ) < 0 and tan(θ) < 0 (Cosine positive). The quadrants in which cosine, sine and tangent are positive are often remembered using a favorite mnemonic.

Answer:

.12

Step-by-step explanation:

The cost of each pencil is 0.12.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given that

Miranda wants to buy pencils printed with the school mascot. The graph below represents the cost for different numbers of pencils.

Number of pencils on x axis and cost on y axis.

We have to take any point from graph.

Let the point be (100,12)

Let x be the cost of each pencil be x.

100x=12

Divide both sides by 100

x=12/100

x=0.12

Therefore cost of each pencil be 0.12

Answer:

Tanisha's lunch cost $9.22.

Step-by-step explanation:

Given that,

Total bill = $18.94

Cost for Madison cost = $9.72

Total cost = Tanisha's lunch + Madison's lunch

18.94 = Tanisha's lunch + 9.72

Tanisha's lunch = 18.94 - 9.72

Tanisha's lunch = 9.22

So, Tanisha's lunch cost $9.22.

Answer:

Least common denominator is the lowest number in similarity that a fraction can share and be divided into

Step-by-step explanation:

For example, in this example 1/5, and 1/2 the least common denominator would be 10 because when putting these fractions together you might want to find the total of what they equal. For example, think of this example as a pizza, to make one whole pizza in the first one would be 5 pieces but instead of all five pieces, all you have left is 1 piece of the five. so you only have 1/5. now just imagine you had another pizza the same size of the first one but instead of five pieces you it's only two pieces however, from this two piece pizza all you have left is 1/2. You want to find the in terms of what fraction would make them both equal each other in which you would eventually be able to find out how much pizza you would have left.  The denominator is the lower number under the fraction where that is the one most needed for a fraction to change. The least common denominator is a number that goes into both fractions that in reverse can be divided by against each other. our denominators are 5 and 2. Numbers that are divisible are 10, 20, 40 and so on since 5x2=10, 2x5=10; 5x4=20, 2x10=20; 5x8=40, 2x20=40. The least common denominator would be the lowest number which in this case would be 10.

Step 1: Simplify both sides of the equation.

0.4(12−3x)=0.3(12x−16)

(0.4)(12)+(0.4)(−3x)=(0.3)(12x)+(0.3)(−16)(Distribute)

4.8+−1.2x=3.6x+−4.8

−1.2x+4.8=3.6x−4.8

Step 2: Subtract 3.6x from both sides.

−1.2x+4.8−3.6x=3.6x−4.8−3.6x

−4.8x+4.8=−4.8

Step 3: Subtract 4.8 from both sides.

−4.8x+4.8−4.8=−4.8−4.8

−4.8x=−9.6

Step 4: Divide both sides by -4.8.

−4.8x /−4.8  =  −9.6 /−4.8

x = 2

Answer:

5 times x minus 8 minus 7

Step-by-step explanation:

whenever you see an x right next to a number, it means that it's being multiplied for that number. For example: 2x mean 2 times x

This symbol - is a minus symbol. So when it's in front of a number, you say "minus" and then the number. For example: 4 - 3 means, Four minus three.

Answer:  rate of change = 2

===============================

Explanation:

Apply the slope formula. I'll use the first two columns as the two points, but you can use any two columns you want.

m = (y2-y1)/(x2-x1)

m = (9-5)/(3-1)

m = 4/2

m = 2

The slope is 2, so the rate of change is 2. Slope and rate of change describe the same thing. Each time x goes up by 1, y goes up by 2.

Answer: t=0.7+1.5

Step-by-step explanation:

The equation that represents the distance from A = (a, b) and B = (c, d) is

√(c - a)² + (d - b)² = 1.5

The distance between two points of a line is given as:

Distance = √(c - a)² + (d - b)²

We have,

Let points A and B have the coordinates.

A = (a, b)

B = (c, d)

Now,

Distance = √(c - a)² + (d - b)²

√(c - a)² + (d - b)² = 1.5

Thus,

The equation is

√(c - a)² + (d - b)² = 1.5
