Answer:

t = 3

Step-by-step explanation:

Given

- 3 (t - 2) + 7t = 9t - 9 ← distribute left side and simplify

- 3t + 6 + 7t = 9t - 9

4t + 6 = 9t - 9 ( subtract 9t from both sides )

- 5t + 6 = - 9 ( subtract 6 from both sides )

- 5t = - 15 ( divide both sides by - 5 )

t = 3

Answer:

t = 3.

Step-by-step explanation:

-3(t - 2) + 7t = 9t - 9   Distribute the -3 over the parentheses:

-3t + 6 + 7t = 9t - 9     Subtract  9t from both sides:

-3t - 9t + 7t + 6 = -9    Subtract 6 from both sides:

-3t - 9t + 7t = -9 - 6  

-5t = -15

t = -15/-5

t = 3 (answer).

You go to the store and pick out 3 apples for $0.60 each, 2 bananas for $0.50 each, and 1 quart of yogurt for $4.50. At checkout
Stella [2.4K]

Answer:

$6.21

Step-by-step explanation:

1 apple = $0.60

3 apples = $1.80 (Multiply 0.60 by 3)

2 bananas = $1.00 (Multiply 0.50 by 2)

1 quart of yoghurt = $4.50

Add the prices up first:

1.80 + 1.00 + 4.50 = $7.30

7.30 off 15% = $6.21

Please help its only A B C D which should equal 105degree to prove that f // g?
ELEN [110]

Answer:

Option (4)

Step-by-step explanation:

From the figure attached,

∠b = 75° [Vertical angles]

If the lines f and g are parallel then,

∠b = ∠c [Corresponding angles]

Therefore, ∠c = 75°

Since m∠c + m∠d = 180° [Supplementary angles]

75° + m∠d = 180°

m∠d = 180° - 75°

m∠d = 105°

Therefore, measure of angle d should be equal to 105° to prove f and g are parallel.

Option (4) will be the answer.

Help me with this problem please a and b

(a) Compare your quadratic for h to the general quadratic ax² +bx +c. Perhaps you can see that ...
  a = -16
  b = 128
You use these numbers in the given formula to find the time when the ball is highest.
  t = -b/(2a) = -128/(2(-16)) = 4 . . . . . . the time at which the ball is highest


(b) Evaluate the quadratic to find the height at t=4.
  h = -16(4)² +128(4) +21
  h = -256 +512 +21
  h = 277
The maximum height of the ball is 277 ft.
