Item 4
Aisha has a piece of string that she cuts into smaller pieces. This line plot shows the length of each piece. Juan has a piece of string that is 12 as long as Aisha's seventh-longest piece. (Note: The problem states the seventh-longest piece, not the seventh-longest length.)

How long is Juan's piece of string?

Answer:

-1/2

Step-by-step explanation:

2x-y=7

y=2x-7

This line has a slope of 2, a line perpendicular to this line will have a reciprocal number to the slope of this line.

Which means another line is perpendicular to this line will have a slope of -1/2

0.65 represent the percent of battery life remaining decreases by 65% each hour. Option D is correct.

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

The fact that the exponential growth function's equation is provided by;

y=a(1+r)ˣ

Given expression;

y = 100(0.65)ˣ

Y represents the percent of battery life

The number of hours x

The battery life percentage declines by 65 percent per hour, or 0.65.

Hence option D is correct.

Answer:

5 years

Step-by-step explanation:

Given that

The current population is 45,000

The rate of interest in declining would be 4.5% per year

The expected population is 35,746

We need to find out the no of years

Since the rate of interest decrease by 4.5% per year so after decreasing it the percentage would be 0.955

Now

Year 1 = 45,000 × 0.955 = 42,975

Year 2 = 42,975 × 0.955 =  41,041.125

Year 3 = 41,041.125 × 0.955 = 39,194.27

Year 4 = 39,194.27 × 0.955 = 37,430.53

Year 5 = 37,430.53 × 0.955 = 35,746.16

Hence, the no of years would be 5

Answer:

$100.80

Step-by-step explanation:

Total money = 28.80 (Jasmine) + 2.5 x 28.80 (Sister)

Total money = 28.80 + 72 = $100.80

Answer:

Answer:

The right solution is:

(1) 138

(2) 22

Step-by-step explanation:

The given values are:

t = 6

c = 3

b = 5

(1)

The given expression is:

=  [tex]120+3t[/tex]

On putting the value of "t", we get

=  [tex]120+3(6)[/tex]

=  [tex]120+18[/tex]

=  [tex]138[/tex]

(2)

The given expression is:

=  [tex]4c+2b[/tex]

On putting the values, we get

=  [tex]4(3)+2(5)[/tex]

=  [tex]12+10[/tex]

=  [tex]22[/tex]

Answer: 5..6 in.

Step-by-step explanation:

Given

Hypotenuse of isosceles triangle is 8 inches

In isosceles triangle two sides are equal

Suppose the other side is x

Using Pythagoras we can write

[tex]\Rightarrow x^2+x^2=8^2\\\Rightarrow 2x^2=64\\\Rightarrow x^2=32\\\Rightarrow x=4\sqrt{2}\approx 5.6\ in.[/tex]

Therefore, the lengths of the legs is 5.6 inches

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

Explanation:

Add up the parallel sides, and divide by 2

x = (15+35)/2

x = (50)/2

x = 25

The midsegment is the average of the two parallel sides.

Answer:270

$2.80

4(.50 + 1(.80

2 + .80 = 2.80

Sylvia bought 4 bananas and an apple for 2.80 dollars.

1 dollars is equal to 100 cents.

To converts dollars to cents we multiply by 100 and to convert cents to dollars we divide by 100.

In the given question

Sylvia bought 4 bananas for 50 cents and 1 apple for 80 cents

So, the numerical expression will be 4 times the cost of 1 banana and 1 times the cost of an apple.

∴ 4(50) + 1(800) cents

= (200 + 80) cents

= 280 cents or (280/100) dollars = 2.80 dollars.

You can tell straight off the bat, it does have a solution, and it isn't infinite solutions. If it had no solution, it would have the same slope but different y-intercepts. If it had infinite solutions, the 2 equations would have to be the exact same. So there is only one solution.

Step-by-step explanation:

Use Desmos graphing calculator

Answer:

x = -2y^2

Explanation Part 1:

It's not vertical, and thus it's not a standard (y = ax^2 + b) parabola.

This must mean it's either x = 2y^2 or x = -2y^2

Explanation Part 2:

You can test values into either one to check if it works

Take (-2, 1) for example, doesn't have to be a precise coordinate pair:

First Equation

x = 2y^2

-2 = 2(1)^2

-2 = 2(1)

-2 = 2

DOESN'T WORK!

Second Equation

x = -2y^2

-2 = -2(-1)^2

-2 = -2(1)

-2 = -2

IT WORKS!

Step-by-step explanation:

Podemos interpretar a questão acima matematicamente como:

3 pacotes = 870 gramas

1 pacote = x

Multiplicação cruzada

3x = 1 × 870 gramas

Divida os dois lados por 3

3x / 3 = 1 × 870 gramas / 3

x = 290 gramas

Portanto, cada pacote conteria 290 gramas de carne moída
