Answer:

4 : 3 > 7 : 9

Step-by-step explanation:

In order to compare two ratios or fractions, we make their denominators equal and then equate their numerators.

4 : 3 =  \frac{4}{3}  =  \frac{4 \times 3}{3 \times 3}  =  \frac{12}{9}  \\  \\ 7 : 9 =  \frac{7}{9} \\  \\  \because \: 12 > 7 \\  \\  \therefore \:  \frac{4}{3} > \frac{7}{9} \\  \\  \implies \: 4 : 3  > 7 : 9

C is the point (-301, 601)<br> Does C lie on the straight line passing through A and B?
Marat540 [252]

Answer:

There is no picture or graph to go with the question so I am afraid I will not be able to give you a specific answer.

To find out if a point (x, y) is on the graph of a line, we plug in the values into that equation and see if we get a true statement, such as 10 = 10. If we get something different, like 6 = 4, we know that the point is not on the line because it does not satisfy the equation. Plug in (-301, 601) into the equation of the line to see whether that point lies on it or not.

Step-by-step explanation:

Suppose the equation of the straight line that passes through E and F is this:

y = 7x + 2

We are to figure out whether or not the point (1, 10) lies on that line. In order to do this we would plug in (1, 10) into the equation, with 1 being x and 10 being y.

10 = 7(1) + 2 = 7 + 2 = 9

10 = 9 is a false statement. Therefore, the point (1, 10) does NOT lie on the line y = 7x + 2.

If you were to provide an image or graph that shows the equation of line AB then perhaps I would be able to answer your question with a specific answer.

If y varies directly as x and y = 24 when<br> x= 16, what is y when x = 50?
mars1129 [50]

Answer:

y = 75

Step-by-step explanation:

Given

y\ \alpha\ \ x

y=24; x =16

Required

Find y when x = 50

We have:

y\ \alpha\ \ x

Express as equation

y = kx

Solve for k

k = \frac{y}{x}

When y=24; x =16

k = \frac{24}{16}

k = \frac{3}{2}

When x = 50, we have:

y = kx

y = \frac{3}{2} * 50

y = 75

A crane lifts a pallet of concrete blocks 7ft from the back of a truck. The truck drives away and the crane lowers the pallet 11
Dmitrij [34]

Answer:

The position of the concrete relative to its initial position is 4ft behind its initial position

Step-by-step explanation:

Let us analyze the problem following the sequence of events.

First of all, the crane is initially 7 ft from the back of the truck.

Once the truck drives away, the crane lowers the concrete at 11 ft away from the back of the truck.

To get this distance relative to the initial position, we have to subtract the initial position from the final position of the concrete.

This will  be

11ft - 7ft = 4 ft

The position of the concrete relative to its initial position is 4ft behind its initial position

11111nata11111 [884]

Answer:

A, C, and then B

Step-by-step explanation:

well 2 because it's the formulas and 4 because a triangular prism is like three triangles standing up hugging each other, so if you cut their heads off, it would be a triangle, because three sides.
