what is 4x8? i really need help with this one.
Answers
Answer:
32
Step-by-step explanation:
The value of 4 x 8 is 32.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
4 x 8
We need to remember the multiplication table of 4 or 8.
Or we can simply add 4 eight times.
We can also add 8 four times.
Now,
4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 32
8 + 8 + 8 + 8 = 32
It's the same value.
Thus,
The value of 4 x 8 is 32.

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
Answers
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

The answer is 5 in a close dot going --->
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.

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?
Answers
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
Answers
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. <

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?
Answers
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.

Step-by-step explanation:
probability of the dice being 5 = 1/6
probability of the dice being a factor of 6 = 4/6
probability of the dice being more than 1 = 5/6
1/6 * 4/6 = 4/36
