Answer:

6 feet

Step-by-step explanation:

240 feet : 10 inches

24 feet    : 1 inch

? feet       : 1/4 inch

to get from 1 to a 1/4 you divide by 4, so you do 24 ÷ 4

24 ÷ 4 = 6

Answer:

6 ft

Step-by-step explanation:

First, make this visually understandable using a ratio:

<u>240 ft</u> = <u>x ft</u>

10 in     \frac{1}{4} in

To find the change between the inches,

1/4 ÷ 10 = 0.025

Use this same amount to find x ft:

240 (0.025) = 6

x = 6 ft

To double-check:

240/10 = 24

6/0.25 = 24

The equation of a line is y=3. Write an equation in slope intercept form of a line parallel to y=3 that passes through (0,6).
Dimas [21]

Answer:

y = 6

Step-by-step explanation:

We have to consider the equation of a line ( in slope - intercept form ) that is parallel to y = 3, and passes through the point ( 0, 6 ). Now y = 3 can be plotted as a horizontal line that passes through the point ( 0, 3 ). If we want a line that is parallel to this, it must be horizontal as well;

Let us consider the second point now. This line must pass through the point ( 0, 6 ). We can conclude that the line must be 1. Horizontal, and 2. Pass through point ( 0, 6 );

Equation - y = 6

Find the equation of the line parallel to y=1/3x-12 and passing through (0,-9)
vladimir1956 [14]
If the line is parallel, the slope must also be 1/3.
Plug in the coordinates of (0,-9) into y=1/3x+b:
1) -9=(1/3)(0)+b
2) -9=0+b
3) b=-9

Two angles of a triangle have the same measure and the third one is 33 degrees greater than the measure of each other two. Fine
gavmur [86]

ill try my best

Add the two angles you already know (for example, 50 and 45), then, with the sum of the two angles (95), subtract it from 180 (180-95) and there's your answer. How do I find the third angle of a triangle if the two known angles are 35 and 40?

The measure of any exterior angle of a triangle is equal to the sum of the measures of its two interior opposite angles. The sum of the three angles of a triangle is 180°. ... The sum of the lengths of any two sides of a triangle is always greater than the length of the third side.

all i got (:

5) What does QRST → Q'R'S'T' mean?
Dima020 [189]

Answer:

QRST becomes Q prime, R prime, S prime, T prime.

Step-by-step explanation:

Any figure that is rotated, translated or reflected on the corrdinate plane is considered a prime (as long as it is congruent (the same as, or equal to) with the original). The apostrophe stands for prime.

Ex. If you reflect triangle ABC across one of the axes, the original triangle will continue being ABC, while the reflection would be A' B' C' (or A prime, B prime, C prime). I hope this helps :)

Lol helppppppppppppp
Dima020 [189]

Answer:

\boxed {x = \frac{10}{c}}

Step-by-step explanation:

Solve for the value of x:

3(cx - 7) = 9

-Divide 9 by 3:

cx - 7 = \frac{9}{3}

cx - 7 = 3

-Add 7 to both sides:

cx - 7 + 7 = 3 + 7

cx = 10

-Take c and divide it on both sides:

\frac{cx}{c} = \frac{10}{c}

\boxed {x = \frac{10}{c}}

Therefore, the value of x is \frac{10}{c}.
