10. Julio is driving to the store. The average distance d, in miles, he travels over t minutes is given by the
function d(t) = 0.5t. What is the value of the function when t = 15?
Answer:
7.5 miles
Step-by-step explanation:
Given the equation d(t) = 0.5t, all you need to do is plug in the value of t.
They're asking what the Function equals, and they're giving you the value of the variable t.
To solve, write the equation d(15) = 0.5(15)
And if you simplify the right side of the equation, you'll find that
d(15) = 7.5
If t represents time, then you can conclude that Julio travels 7.5 miles in the time t, of 15 minutes.
SOMEONE PLS HELP !! In a randomly generated list of numbers from 0 to 4, the chance that each number can occur is 1/4. True or False?
Answer:
False
Step-by-step explanation:
This is false because there are 5 numbers from 0 - 4 (0, 1, 2, 3, 4) so the probability will be 1/5 not 1/4.

Molly spent 1 hour and 30 minutes swimming 5 laps in the river. If it took her the same time to swim each lap, how long would it take her to swim 7 laps?
Answer:
126 minutes or 2 hours and 6 minutes
Step-by-step explanation:
Find how long it took her to swim one lap
1 hour and 30 minutes = 90 minutes
90/5 = 18
This means it took her 18 mins to swim each lap
18 · 7 = 126
It took her 126 minutes/2 hours and 6 minutes to swim 7 laps
126 hours (aka 2 hours and 6 minutes)
That is the Answer.
ABC is a straight line.
+
H
B
C
The length AB is five times the length BC.
AC = 90 cm.
Work out the length AB.
AB = cm
Answer:
AB = 75 cm
Step-by-step explanation:
Since ABC is a straight line, then
AB + BC = AC
let BC be x then AB = 5x and summing gives
5x + x = 90
6x = 90 ( divide both sides by 6 )
x = 15
Thus
AB = 5x = 5 × 15 = 75 cm

The volume of right circular cylinder A is 22 cubic
centimeters. What is the volume, in cubic
centimeters, of a right circular cylinder with twice the
radius and half the height of cylinder A?
A) 11
B) 22
C) 44
D) 66
Answer:
44
Step-by-step explanation:
we know that
[volume of right circular cylinder]=pi*r²*h
Vo=pi*r²*h--------------> original volume
Vo= 22 cm³
if twice the radius and half the height
r1=2*r
h1=h/2
then
V1=pi*ri²*h1
substituting
V1=pi*(2*r)² *(h/2)----------->V1= pi*4*r² *h/2-----------> V1=2*pi*r² *h
V1=2*[pi*r² *h]------------> V1=2Vo
V1=2*22=44 cm³
Which statements are true about the parabola represented by the equation y=−3x^2+18x+23 Select all that apply. 1. The leading coefficient is positive, so the parabola opens up. 2. The leading coefficient is negative, so the parabola opens down. 3. The parabola has a maximum. 4. The parabola has a minimum.
Answer:
2, 3
Step-by-step explanation:
2. The leading coefficient is -3. When the leading coefficient is negative, the parabola opens down.
3. When the parabola opens down, it has a maximum point, but no minimum point. (when the parabola opens up, it has a minimum, but no maximum)
I hope this helps :)
The right statements about equation y=−3x^2+18x+23 is 2) The leading coefficient is negative and 3) The parabola has a maximum.
What is a parabola?A parabola is a plane curve which is mirror-symmetrical and can be downward, upward, leftward and rightward shaped.
What are the statements?Second is true because when the coefficient is negative the parabola opens down because their values starts decreasing.
Third is true because when the parabola opens down it has a maximum point and no minimum point. On the other hand when the coefficient is positive it opens up.

Answer:
well 6/20 has more absolute value than 7/30
Step-by-step explanation:
also 7/30 is closer to zero
Comparison of 30% has more absolute value than 23.3%
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
Let x = 6 broken bulbs out of 20
y = 7 broken bulbs out of 30
x = 6/20
x = 0.3
There are 30% bulbs broken out of 20
y = 7/30
y = 0.233
There are 23.3% bulbs broken out of 20

A model rocket is launched from ground level. Its height, h meters above the ground, is a function of time t seconds after launch and is given by the equation h=-4.9t^2+68.6t What would be the
maximum height, to the nearest meter, attained by the model?
Answer:
240 m to nearest meter.
Step-by-step explanation:
h = -4.9t^2 + 68.6t
We need to convert this to vertex form to find the maximum value of h:
h = -4.9(t^2 - 14t)
h = -4.9[(t - 7)^2 - 49]
h = -4.9(t - 7)^2 + 240.1
So maximum height is when t = 7 and it's 240.1 meters.
Which symbol would make the statement TRUE?
4.589 4.958
A. <
B. >
C. =
D. none of the above
Answer:
A. <
Step-by-step explanation:
The symbol "<" means less than.
Comparing 4.589 with 4.958, 4.958 is greater than 4.589 by 0.369 (4.958 - 4.589).
So therefore, if we are to write 1 statement for both, we would say "4.589 is less than 4.958".
This can be written by using just symbols without words, thus, we have:
4.589 < 4.958.
The correct option is A. <

Which is D.)
The picture is to show how it looks in Plato.
Answer: D.
Step-by-step explanation:
If they already have 565 cans and 87 will bring cans then we could represent it by the inequality
87x + 565[tex]\geq[/tex] 1000 where x is the number of cans each guest much bring to meet the goal. so solve for x.
87x + 565[tex]\geq[/tex] 1000
-565 -565
87x [tex]\geq[/tex] 435
x [tex]\geq[/tex] 5
since we now that x is 5 then A and C can't be answers.
B can't be an answer in this case because 5 is excluded but they actually need at least 1000 bottles so 5 needs to be excluded.

SOLVE APPLICATION USING ALGEBRA. TYPE THE EQUATION OR INEQUALITY AND PLEASE SHOW WORK. a) A rectangle with perimeter 18 cm has length that is 3 cm more than twice its width. Find the dimensions of the rectangle.
Answer:

Step-by-step explanation:
[tex]l+l+w+w=18\\\\2w+3=l\\\\2w+3+2w+3+w+w=18\\6w+6=18\\6w=12\\w=2\\\\2w+3=l\\2*2+3=l\\4+3=l\\l=7[/tex]
Answer:
3 cm by 6 cm
Step-by-step explanation:
Represent the length and width by L and W.
The perimeter is P = 2L + 2W, and here the perimeter is 18 cm.
Finally, L = W + 3 cm. substituting W + 3 cm for L in the above equation, we get:
18 cm = 2(W + 3) + 2W, or (after reduction)
9 cm = W + 3 cm + W
Then 2W = 6 cm, or W = 3 cm.
Then the length is L = W + 3, or 3 cm + 3cm = 6 cm
The dimensions of the rectangle are 3 cm by 6 cm.
Check: Does 2(3 cm) + 2(6 cm) = 18 cm? Yes
