HELP NEEDED PLEASE! Solve for x, rounding to the nearest tenth.

Mathematics
1 answer:
KonstantinChe [14]3 years ago
5 0

Answer:

C. x = 6.0

Step-by-step explanation:

If you use the Pythagorean Theorem, you'll see that x^2 + 5^2 = 8^2. That'll simplify down to

x^2 + 25 = 64. Then you subtract 25 from 64 and that'll give you 39. You then have to find what √39 is and that is 6.244, so that is 6.0 simplified to the nearest tenth.

One winter day, the outside temperature, y, was never below −1°. The inside of a car was always warmer than the temperature outs
sammy [17]

Answer:

The correct option is;

On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal to the y-axis at y = negative 1, Everything above the line is shaded. The second dashed line has a positive slope and goes through (0, negative 4) and (2, negative 2). Everything above and to the left of the line is shaded

Step-by-step explanation:

The inequality representing the first line is y ≥ -1

The inequality representing the second line is y > x + 4

Therefore, the first line is a solid horizontal line with the shaded region above the line

The second line is a line with a broken line with positive slope slope with the shaded region being above the line and to the left

For each trip, a taxi company charges a fixed fee of $2.00 plus $0.75 for each 1/2 mile or fraction of 1/2 miles. If, for every
nydimaria [60]

Answer:

E: 2.00 + 0.75 [ 2r]

Step-by-step explanation:

r represents the number of miles. For each 1/2 mile the taxi will charge and extra free of $0.75. Then, for each mile, the taxi will charge $0.75*2. For example:

For a trip of 1 mile the taxi will charge:

$2.00+$0.75*2

For a trip of 2 miles, the taxi will charge:

$2.00+0.75*4

For a trip of 10 miles, the taxi will charge:

$2.00+$0.75*20

Notice that the variable fee (the one that depends on the number of miles) is $0.75 times the double of miles. In each case the number of miles is multiplied by two. Then the correct answer is E: 2.00 + 0.75 [ 2r]

I F 49x ²b = (7x +1/2)(7x-1/2)<br>then Find the value b.​
Marina86 [1]

Answer:

0

Step-by-step explanation:

Apply Only the Outside and Inside Method of the Foil Method.

7 \times  -  \frac{1}{2}  =  - 3.5x

\frac{1}{2}  \times 7x = 3.5x

Add them together

- 3.5x + 3.5x = 0

So our b value is 0.
