Answer:
8 cubes
Step-by-step explanation:
Given
Prism
Dimension: 6 ft by 3 ft by 1 ft
Cube
Dimension: 1.5 ft by 1.5 ft by 1 ft
Required
The number of cubes in the prism
First, calculate the volume of the prism
[tex]V_1 = 6 * 3 * 1ft^3[/tex]
[tex]V_1 = 18ft^3[/tex]
Next, the volume of the cube
[tex]V_2 =1.5 * 1.5 * 1ft^3[/tex]
[tex]V_2 =2.25ft^3[/tex]
The number of cubes is calculated by dividing V1 by V2
[tex]Cubes = \frac{V_1}{V_2}[/tex]
[tex]Cubes = \frac{18}{2.25}[/tex]
[tex]Cubes = 8[/tex]

The time is 6o'clock. What are the next two times at which the hour and minute hands will be perpendicular?
Answer:
The two times are 6:15 and 6:45
Step-by-step explanation:
Given
[tex]Time = 6\ O'\ clock[/tex]
Required
Next two times which the hour and minute hands are perpendicular
For a time to have perpendicular hands, the difference between the hour and minute hands must be 15 minutes.
Having said that:
15 minutes after 6 O' clock is: 6 : 15 (This is perpendicular)
15 minutes after then is 6 : 30 -- This is not perpendicular
15 minutes after then is 6 : 45 -- This is perpendicular
Hence, the two times are: 6:15 and 6:45
What are the steps to solving the equation: -3w+9= -12
Answer:
Simplify each side of the equation by removing parentheses and combining like terms.
Use addition or subtraction to isolate the variable term on one side of the equation.
Use multiplication or division to solve for the variable.
Step-by-step explanation:
Answer:
Solution
= −7
Step-by-step explanation:
3 + 9 = − 12
3 + 9 − 9 = − 12 − 9
Subtract the numbers
Subtract the numbers
3 = − 21
Divide both sides of the equation by the same term
3 = − 21
3/3 = −21/3
Solution
= −7

a. Solve 2x + 6 < 10.
b. Solve - 2x + 22 < 18.
Answer:
2
Step-by-step explanation:
1 Subtract 66 from both sides.
2x=10-6
2x=10−6
2 Simplify 10-610−6 to 44.
2x=4
2x=4
3 Divide both sides by 22.
x=\frac{4}{2}
x=

to 22.
x=2
x=2
Done
2x+22=18
We move all terms to the left:
2x+22-(18)=0
We add all the numbers together, and all the variables
2x+4=0
We move all terms containing x to the left, all other terms to the right
2x=-4
x=-4/2
x=-2

We have given that,
The function, f(x) = sec(x), is plotted below.
On a coordinate plane, parabolas repeat.
What is the limit?
The limit is a value that a function (or sequence) approaches as the input (or index) approaches some value.
A parabola opens up approaches StartFraction pi Over 2 EndFraction, has vertex (0, 1), and approaches StartFraction pi over 2 EndFraction. The parabola flips over the x-axis at every measure of pi.
We have to determine the value for which values of x is the limit positive infinity when x approaches the values from the left.

Solve the system of equations:
2x + 3y = 10
x - 2y = -2
(2,1)
(0,1)
(0,2)
(2,2)
No solution
Answer:
(2,2)
Step-by-step explanation:
2x+3y=10
x−2y=−2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
2x+3y=10,x−2y=−2
To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.
2x+3y=10,2x+2(−2)y=2(−2)
Simplify.
2x+3y=10,2x−4y=−4
Subtract 2x−4y=−4 from 2x+3y=10 by subtracting like terms on each side of the equal sign.
2x−2x+3y+4y=10+4
Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.
3y+4y=10+4
Add 3y to 4y.
7y=10+4
Add 10 to 4.
7y=14
Divide both sides by 7.
y=2
Substitute 2 for y in x−2y=−2. Because the resulting equation contains only one variable, you can solve for x directly.
x−2×2=−2
Multiply −2 times 2.
x−4=−2
Add 4 to both sides of the equation.
x=2
The system is now solved.

50 pts if you help don't be a brainly will take it down if you do and you wont get the points
Answer:
21
Step-by-step explanation:
It landed on 4 and 5 about 37% of the time with 240 rolls. So since 60 is 1/4 of 240, we just divided the number of times it landed on 4 and 5 by 4. So since it landed on 4 or 5 84 times, we divide 84 by 4
84 ÷ 4 = 21
So the number of times the cube will land on 4 or 5 is 21

Based only on the information given in the diagram, which congruence
theorems or postulates could be given as reasons why ADEF= AKLM?
Check all that apply.
AA
O A. LA
ОВ. НА
O C. AAS
D. SAS
E HL
F.LL
=================================================
Explanation:
LA stands for Leg Angle. More specifically, the angle is an acute angle. This theorem only works for right triangles. We see that ED = LK which is one pair of congruent leg segments. So that takes care of the L part of LA. However, we don't know anything about the acute angles. We don't know if angle E = angle L, or if angle F = angle M, or something along those lines. We need angle markers to tell us or not.
In short, we only have half the info needed for LA, so we must cross choice A off the list.
----------------
HA stands for hypotenuse angle, or hypotenuse acute angle, and this rule only applies for right triangles. We don't know anything about the hypotenuse lengths if they are the same or not.
Similar to choice A, we don't know anything about the acute angles either.
Those two facts mean we must cross off choice B.
----------------
AAS stands for Angle Angle Side. The order is important because the side is not between the angles. The diagram only shows one pair of angles that are congruent to one another. That pair being the 90 degree angles indicated with the square marker. We don't have another pair of angles, so we cannot use AAS.
Cross choice C off the list.
-----------------
We can use SAS because we have two pairs of congruent sides and one pair of congruent angles.
The congruent sides are
ED = LK (double tickmarks)DF = KM (single tickmarks)That takes care of the two "S"s of "SAS". The "A" would be those two right angles which are congruent to one another. The angles are between the congruent sides which is important. Recall that SSA is not a valid congruence theorem.
So that's why choice D is the only answer.
-----------------
Side note: We could use the LL theorem, where L stands for leg, since we are given two pairs of congruent legs for each triangle. Like LA and HA, this only applies to right triangles. LL is a special case of SAS. However, LL isn't listed so we'll just be sticking with SAS as the only answer.

I need help with the equation.
Answer:
(x - 3)² + (y + 9)² = 25
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Given area = 25π , that is
πr² = 25π ( divide both sides by π )
r² = 25 ( take the square root of both sides )
r = [tex]\sqrt{25}[/tex] = 5
With centre (h, k) = (3, - 9 ) and r = 5 , then
(x - 3)² + (y - (- 9) )² = 5² , that is
(x - 3)² + (y + 9)² = 25
