Answer 2

Answer:

Step-by-step explanation:

h(t)=30000-2000t

A) h(5)=30000-2000(5)=20000ft

B) h(8)=30000-2000(8)=14000ft

C) h(12)=30000-2000(12)=6000ft

Which number will be closest to 14? A. 13.4 B. 13 1\2 C. 13.08 D. 13 2\5​

Answers

Answer:

13.08

Step-by-step explanation:

Its the closest

Answer:

13.5

Step-by-step explanation:

Convert fractions to decimals.

13 and 8/100 is 13.08

13 1/2= 13.5

13 2/5= 13.4 (13.4 and 13 2/5 are the same)

So your options are 13.5, 13.4, 13.08.

Round decimals up or down.  When rounding to the nearest hundredth (50 and above rounds up, below fifty rounds down. Ex. 13.5 (13.50) rounds to 14 whereas 13.4 (13.40) and 13.08 round back down to 13)

Amanda and Carly have the same percentage of green marbles in their bags of marbles. Amanda has 4 green marbles and 16 total marbles. Carly has 10 green marbles. How many of Carly's marbles are NOT green?​

Answers

Answer:

30

Step-by-step explanation:

They both have the same percentage of green marbles, Amanda has 16 total marbles, 4 of them are green. So 25 percent of her marbles are green. If 25 percent of Amandas marbles are green, 25 % of Carlys marbles are green too. Carly has 10 green marbles, if 10 is 25 percent of the total amount then the total amount if 40, minus 10 from 40 because we only want the non green ones and the answer is 30. :)

If a quadratic function has an axis of symmetry of x = 2 and a zero of-1. Which of the
following is the other zero?

Answers

The line of symmetry is the center/ middle of the parabola where the curve shifts. Since the line of symmetry is at x=2 and the zero is at x= -1, you have the find the difference between the values which is 3. So the other zero is three the right of the line of symmetry at x= 5.

Triangle RST and its image, triangle R’S’T’, are graphed on the coordinate grid below.

Which rotation, using the origin as the center of rotation, transformed RST to R’S’T’?
A. a 90° clockwise rotation
B. a 90° counterclockwise rotation
C. a 45° clockwise rotation
D. a 45° counterclockwise rotation

Answers

Answer:

B. a 90º counterclockwise rotation

Step-by-step explanation:

You can tell that it moves 90º and it moves in a counterclockwise direction because from RST to R’S’T’ it moves left to right. That is counterclockwise when you look it up.

Find the distance between the two points rounding to the nearest tenth (if necessary).

(−1,−2) and (5,2)

Answers

Answer:

7.2 units

Step-by-step explanation:

To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Plug in the given values of (-1, -2) & (5, 2)

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(5 - (-1))² + (2 - (-2))²]

Simplify the parentheses.

d = √[(5 + 1)² + (2 + 2)²]

d = √[(6)² + (4)²]

Simplify the exponents.

d = √[36 + 16]

Add.

d = √[52]

Evaluate the radical.

Find the diameter of a circle with a circumference of 27 centimeters. Use 3.14. Round to the nearest tenth.

Answers

Answer:

The diameter of the circle is 5.6 cm

Step-by-step explanation:

To solve this problem we need to use the circumferenc formula of a circle and clear d:

c = circumference  = 27cm

d = diameter

π = 3.14

c = π * d

d = c / π

we replace with the known values

d = 27cm / 3.14

d = 5.599

The diameter of the circle is 5.599 cm

round to the nearest tenth

d = 5.599 cm = 5.6 cm

The diameter of the circle is 5.6 cm

Find the height of a cone with a diamater of 12m whose value is 151 meters cubed, then round it to the nearest meter

Answers

Answer:

Height= 4m (nearest meter)

Step-by-step explanation:

[tex]\boxed{volume \: of \: cone = \frac{1}{3} \pi {r}^{2}h }[/tex]

Diameter= 2(radius)

Given that the diameter is 12m,

radius of cone

= 12 ÷2

= 6m

Let the height of the cone be h meters.

[tex]151 = \frac{1}{3} \pi(6^{2} )(h)[/tex]

[tex]151 = 12\pi h[/tex]

[tex]h = \frac{151}{12\pi} [/tex]

h= 4.0054 (5 s.f.)

Thus, the height of the cone is 4m. (nearest meter)

I'll just do red for now, but if you're very desperate I guess I'll help with a few more lol. It's just a lot of typing and my computer is at 6% :)

RATIO:

Ratios are another way of comparing things. It's almost like a fraction, except that it can look like x:y.

I'm guessing you're comparing all of the reds to the total amount, which should be 39. Put 5 in for x and 39 for y to make it look like 5:39.

DECIMAL:

Oh decimals are so fun...

Just divide 39 by 5. The answer to red's decimal is 7.8.

PERCENTAGE:

Percentage can come a little bit confusing to some people, so I'll explain this the best I can.

Basically, all you have to do to find it is divide the number you're making into a percentage by the total amount, then multiply it.

5/39 x 100

0.1282051282 x 100

12.8205128205

I'm going to the nearest hundredth which is 12.82.

Your percentage is %12.82

(If you're rounding to the nearest whole number, it'll be %13)

THEORETICAL:

For this simplify your ratio. 5/39 cannot simplify, so just leave it as 3/39.

Sorry, sometimes I come out a little confusing, so just try not to think too hard about what I'm trying to say if you're confused more lol. Anyway my computer is going to die so I'll go now :)
