Answer:

1 3/4

Step-by-step explanation:

We can set the length of the rectangle to l. We can make an equation with the area because we know length*width = area.

l*(4/5) = 7/5

4l = 7

l = 7/4 = 1 3/4

Answer:

-1/10

Step-by-step explanation:

Let's solve your equation step-by-step.

5x=−1/2

Step 1: Simplify both sides of the equation.

5x= -1/2

Step 2: Divide both sides by 5.

5x/5 = -1/2/5

x=-1/10

Answer:

The correct answer is A.) 45 + 70x < 250.

y = mx + b

She started at 45 miles (+ 45).

She has to go at least 250 miles (< 250).

She is driving at a constant, unchanging speed of 70 mph (70x).

Answer is 8

Answer:

h = 24 cm

Step-by-step explanation:

By using the similar triangle property in the given triangles,

Since, ΔBCD ~ ΔBAE

Their corresponding sides will be in the same ratio,

[tex]\frac{BC}{BA}= \frac{CD}{AE}= \frac{BD}{BE}=\frac{a}{h}[/tex]

[tex]\frac{CD}{AE}=\frac{a}{h}[/tex]

[tex]\frac{10}{20}=\frac{(36-h)}{h}[/tex]

10h = 20(36 - h)

10h = 720 - 20h

30h = 720

h = 24 cm

Therefore, height h = 24 cm is the answer.

Answer:

b

Step-by-step explanation:

if you say 1<2 and multiply both by negative 3 you will have -3 > -6

Answer:

Step-by-step explanation:

When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number. You can also consider this with a number line.

Answer:

D: 7x + 5y ≥ 200

Step-by-step explanation:

If flowers sell for $7 and candles sell for $5, we can write those as 7x and 5y. Now, our inequality is 7x + 5y __. The words "at least" can translate to greater than or equal to. The symbol for that is ≥. Now, he wants to sell at least $200 worth of goods. That means we can write our inequality as 7x + 5y ≥ 200.

Answer:

5(3x - 9)

3(5x - 45)

Step-by-step explanation:

If you simplify the expression "Andre" wrote, you would get 15x - 45 and just need two other expressions that equal 15x - 45. In this problem it's simple since only 3 and 5 can multiply to make 15 besides 1 and 15, which is used in the expression "Andre" wrote, meaning it couldn't be used.

Answer:

not similar

Step-by-step explanation:

similar means proportional

1, 1, and 0.5 are not proportional to 3.5, 3, and 2.25

As the two side lengths of the smaller triangle is the same but the ratio of those side in a larger triangle and the smaller triangle is different they are, D. Not similar.

We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.

We know two triangles are similar if the ratios of their corresponding sides are equal.

The larger triangle has sides 3, 3.5, and 2.25.

And the smaller triangle has sides 1, 1, 0.5.

As the smaller triangle has side lengths 1, 1, and the ratio of the sides of the larger triangle and the smaller triangle is (2 + 1)/1 and (2.5 + 1)/1 which is equal to 3/1 and 3.5/1 3 and 3.5 but the smaller side has 1 and 1, therefore, they are not similar.

The inequality -2 [tex]\frac{3}{4}[/tex] < -1 [tex]\frac{2}{4}[/tex] is correct.

Step-by-step explanation:

-2 [tex]\frac{3}{4}[/tex] is greater than -1 [tex]\frac{2}{4}[/tex] because the more left the number is on the number line, the smaller.

Answer: 100 x 2^ t/9

Step-by-step explanation:

The initial population of 100 that doubles in 9 years, gives the

expression for population as; [tex]\underline{ P = 100 \cdot e^{0.077 \cdot t}}[/tex].

Given parameters are;

The time it takes the population to double = 9 years

The initial population count = 100

Required:

The expression that gives the population after t years.

Solution:

The population as a function of time can be expressed as an

exponential function as follows;

[tex]P = \mathbf{P_0 \cdot e^{c \cdot t}}[/tex]

At the start, t = 0, P = 100, we have;

[tex]100 = \mathbf{ P_0 \times e^{c \times 0} }= P_0[/tex]

Therefore;

P₀ = 100

After 9 years, we have;

P = 2·P₀

Therefore;

[tex]2 = \mathbf{ e^{c \times 9}}[/tex]

ln(2) = 9·c

[tex]c = \dfrac{ln(2)}{9} \approx 0.077[/tex]

The function that gives the population is therefore;
