Answer:

30 cm

Step-by-step explanation:

So what we are given here is a case of similar figures.

When we are given similar figures, the ratio of the width of both figures should be similar to the ratio of the length of both figures.

I'll demonstrate it in the following problem.

We know one rectangle has a length of 18 cm and a width of 6cm.

The other rectangle has a width of 10 cm.

Let's take a ratio of the width of both rectangles.

We take the width of 6 cm for the first rectangle to the width of 10 cm for the second rectangle.

w1 = 6 cm

w2 = 10 cm

6 cm : 10 cm = 3 : 5

The ratio given is 3 : 5. Let's use these ratios to find lengths.

l1 = 18 cm

l2 = x cm

3 : 5 = 18 : x

To find x, we just solve this like an equation, where we let ratios be division signs.

3/5 = 18/x

Multiply both sides by 5x

3x = 90

Divide both sides by 3

x = 30 cm

The length of the missing side is 30 cm. We found the answer to the length by using the ratios obtained from the widths.

When you calculate it -4/3 times is 4 so add 4 to that and you get 4. Hope this helps

Answer:

Step-by-step explanation:

To solve for t, you have to isolate it on one side of the equation.

First, you have to switch sides.

→ -9+4t=-17

Add by 9 from both sides.

[tex]\Longrightarrow: \sf{-9+4t+9=-17+9}[/tex]

Then, you solve it.

-17+9=-8

4t=-8

Divide by 4 from both sides.

[tex]\sf{\dfrac{4t}{4}=\dfrac{-8}{4}}[/tex]

Solve.

Divide the numbers from left to right.

-8/4=-2

[tex]\Longrightarrow: \boxed{\sf{t=-2}}[/tex]

I hope this helps. Let me know if you have any questions.

Answer:

[tex]t = -2[/tex]

Step-by-step explanation:

Step 1:  Add 9 to both sides

[tex]-17 = -9 + 4t[/tex]

[tex]-17 + 9 = 4t - 9 + 9[/tex]

[tex]-8 = 4t[/tex]

Step 2:  Divide both sides by 4

[tex]\frac{-8}{4} = \frac{4t}{4}[/tex]

[tex]-2 = t[/tex]

Answer:  [tex]t = -2[/tex]

angle 4+ angle 5 = 180

40+ angle 5 = 180

angle 5 = 140

Answer:

A. 140

Step-by-step explanation:

well, one way to look at it is that ∠4 + ∠5 = 180

we are GIVEN the info that ∠4 = 40

therefore 180 - 40 - ∠5

180 - 40 = 140

Equation: y = x - 1

Step-by-step explanation:

Given: y = x - 6

Slope-Intercept Form: y = mx + b -

where:

Note: parallel lines have the same slope

1. Determine the slope and y-intercept of the given equation:

⇒ y = x - 6 has a slope of 1, and a y-intercept of -6

2. Find the equation of the line parallel line that passes through the point (-5,-6):

⇒ y = x + b [substitute -5 for x and -6 for y]

⇒ -6 = -5 + b [add 5 to both sides]

⇒ -6 + 5 = -5 + 5 + b

⇒ -1 = b

Equation: y = x - 1

3. Check your answer using point (-5, -6):

⇒ y = x - 1

⇒ -6 = -5 - 1

⇒ -6 = -6 ✔

This statement is correct

Therefore, the equation of the line is y = x - 1

Answer: 5,998,000

Step-by-step explanation:

2x10^3= 2,000

6x10^6= 6,000,000

In translation, Use 1 x The Initial SIG FIGS, or first numbers. 10x10 is 100, and notice how 10 and 10 have 2 zeros, so 1x1 = 1 +00 is a way to construct the number.

In this case, the 10^x, the x can represent the number of zeros after our first value.

So, 6 + six zeros, or 6,000,000

and, 2 + 3 zeros, or 2,000

To find the difference, subtract the numbers from eachother and extract the absolute value, (meaning the final answer won't be negative).

So, 6,000,000 - 2,000 = 5,998,000, which is the answer to the prompt!

The average change in distance for each increase of 1 in the iron number is -10, and the y-intercept of the graphs are not the same

From the graph, we have the following points:

(x,y) = (4, 145) and (3,155)

The average change in distance is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{155 - 145}{3 - 4}[/tex]

Evaluate

m = -10

Hence, the average change in distance for each increase of 1 in the iron number is -10

The rate, -10 in (a) means that:

The distance decreases by 10 yards for each number of iron

The y-intercept is the point where the graph crosses the y-axis

From the attached graphs, we have:

Hence, the y-intercept of the graphs are not the same
