Answer:

0.88 (I think this is how Mrs. Futch wants it to be written)

Step-by-step explanation:

h=-16t^2+14t

(Substitute h with 0)

0=-16t^2+14t

(Factor)

0=2t(-8t+7)

2t=0               -8t+7=0

t=0                  t=0.88

{0, 0.88}

Answer:

A

Step-by-step explanation:

use both points to find the slope using the equation

y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3

then the y int can be any y point, so either -2 or 4. in this case they used 4.

Answer

C because 2 quarts make's one gallon

Step-by-step explanation:

Answer:

Child = $ 10.00

Adult = $ 14.00

Step-by-step explanation:

The short answer is that algebra doesn't work that way. You wouldn't divide *everything* by 2, but every term that contains a factor of 2.

In the expression

2 (6x - 1) + 2 (2x + 5)

both terms have a factor of 2 (the 2 out in front of them). They're the ones that get canceled when dividing by 2:

(2 (6x - 1) + 2 (2x + 5)) / 2 = 2/2 (6x - 1) + 2/2 (2x - 5)

… = 1 (6x - 1) + 1 (2x - 5)

… = (6x - 1) + (2x - 5)

and so on.

Looking ahead, it turns out that the equation is solved by x = 7. This makes 6x - 1 = 41 and 2x + 5 = 19. So the equation is saying that, if you make these replacements,

2×41 + 2×19 = 120

If you divide *everything* on the left by 2, you end up with fractions:

(2/2)×(41/2) + (2/2)×(19/2) = 41/2 + 19/2

but 41 + 19 = 60, so the end result would be 30, but that's not the same as 120/2 = 60.

Answer:

a.  90 degrees (given)

b. 270 degrees (360-90)

c. 16π  (Circumference= diameter * π, diameter= 2r= 2(8)=16, so c= 16*π)

d. 4π (That section is a semicircle, so length should be 1/4 the circumference)

e. 12π (This section is 3/4 the circumference)

f. 64π (Area= πr^2, and r^2= 8^2= 64, so 64π)

g. 16π (That section is 1/4 the area)

Answer:

28 Grams

Step-by-step explanation:

each half cup is 4 Grams and you have 3 and a half cups so you take 3x2 which is 6 and then you do 6x4 which is 24 and you add another 4 cause of the extra half. hope this helps. :)

Answer:

21°

Step-by-step explanation:

Since these are both equivalent right triangles, ∡RQY and ∡PQY are the same. So set them equal to each other.

x=3

Next plug x into ∡RQY

16(3)-27=21°

Answer:

24y - 32

Step-by-step explanation:

You take the 8 and multiply each term by in the parentheses by 8, so

8(3y - 4) becomes 8 * 3y - 8 * 4 = 24y - 32

Answer:

well, you can multiply them, to simplify the equation, but to expand, try adding or multiplying 2 multiples of 8, in the middle the 4 can change by adding 2+2 or 3+1. For 3y, you can do 3*y.

Step-by-step explanation:

Answer:

slope = 0  

Step-by-step explanation:

1) Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to solve for the slope. Use the x and y values of the given points, substitute them into the formula, and solve like so:

[tex]m = \frac{(4)-(4)}{(8)-(-9)} \\m = \frac{4-4}{8+9} \\m = \frac{0}{17} \\m = 0[/tex]

Thus, the slope is 0.

The unit rate of the silver chain is $0.44 per inch.

Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.

Given here: 16 inches of silver chain costs $36 and 18 inches cost $40.50

Thus we have the unit rate( dollar/inch) =36/16=40.50/18=4/9

Therefore the unit rate is given by 4/9 or 0.444 dollar per inch.

Hence, The unit rate of the silver chain is $0.44 per inch.
