Answers

Answer:

The area is 5 cm

Answer:

5 cm²

Step-by-step explanation:

The diagonal divides the rectangle into 2 right triangles with legs 5 and 2

The area (A ) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Madison and Tanisha went out to lunch. The bill came to $18.94. Madison knows that her lunch cost 9.72. How much did Tanisha's lunch cost?

Answers

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.

This year, there are 220 farmers raising chickens in the county. This is a 30% increase over last year. How many farmers raised chickens last year?

Answers

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.

what is the percent rate of change in function y = (0.98) ^ x? determine whether the function represents exponential growth or exponential decay​

Answers

C. 2%; exponential decay

You can use the fact that increasing power of values lying between 0 and 1 results in less and less values.

The percent rate of change in given function is -2%

The function represents exponential decay.

Given that:The function: [tex] y = (0.98) ^ x[/tex]To find:Percent rate of change in given function.Is it representing exponential growth or exponential decay?

Finding percent rate of change in given function:


For finding this, first find how much the output y changes if we change x from x to x + 1.

Output when x = x:   [tex]y = (0.98)^x[/tex]

Output when x = x+1:  [tex]y = (0.98)^{x+1}[/tex]

Difference in output if x goes from x to x+1: [tex](0.98)^{x+1} - (0.98)^x = (0.98)^x(0.98 - 1) = -0.02 \times (0.98)^x[/tex] (this change occurs if we increase input x by 1 unit, thus this also represents the rate)

Rate of change of function per unit increment = [tex]-0.02 \times (0.98)^x[/tex]

The percentage of rate of change is found as:

[tex]\text{Percent rate of change\:} = \dfrac{\text{Rate of change} \times 100}{\text{previous value}} = \dfrac{-0.02 \times (0.98)^x \times 100}{(0.98)^x} \\\\ \text{Percent rate of change\:} = -2\%[/tex]

Thus, the percent rate of change is -2%

The negative sign shows that the value is decreasing, thus showing that function shows exponential decay.

What is the rate of change of the table shown?​

Answers

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.

Please i don’t understand this i don’t understand the least common denominator and how can i write an equivalent fraction.please help me my exam is tomorrow

Answers

Basically you find the least possible denominator you can use to make both fractions have the same denominator. The LCD for 5 and 2 is ten because they’re multiplied together, so 1/5 would be 2/10 and 1/2 would be 5/10, if that makes sense. You multiply the numerator by whatever you multiply the denominator by. 2/3 could also be 4/6 or 8/12 or 200/300. The Lcd of 5/8 and 2/4 would be 8, since 5/8 can’t be simplified but 2/4 can be multiplied by 2 to get 4/8 to make the fractions easier to understand. Some fractions aren’t as easy to simplify like 5/19 and 3/26 would be 130/494, and 57/494 respectively. The LCD is just the two denominators multiplied together, as they don’t have any common factors except the numbers multiplied which is 494.

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.

Answers

Step 1: Simplify both sides of the equation.

(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
