Answer:
50cm or 500 mm
Step-by-step explanation:
A quadrilateral is a four sided figure. So, the base of the quadrilateral pyramid has four sides. It also has 4 edges and 4 bases
sum of edges = sum of base edges + sum of lateral edges
1cm = 10mm
55mm = 5.5cm
sum of base edges : 5.5 x 4 = 22cm
sum of lateral edges : 7 x 4 = 28 cm
22 + 28 = 50 cm or 500mm
At Happy Pizza, an 8-inch pizza costs $6.00 and a 16-inch pizza costs $14.00. Which pizza is a better deal?
Answer:
8-inch pizza
Step-by-step explanation:
Answer:
A 16-inch pizza is the better deal, because its twice the size of the 8-inch and you would have to buy two to equal a 16-inch, but it would cost more. So a 16-inch would be a better deal.

Five boys each have 8 marbles. If all
their marbles are collected and placed
into
8heaps, how many marbles will there be in each jeap ?
5 marbles.
We first need to find how many marbles we have in total.
8 marbles * 5 boys = 40 marbles.
These 40 marbles will now be divided by 8, since we are taking the total amount of marbles we have and separating them into 8 different piles.
40/8 = 5
There will be 5 marbles in each heap.
Use words to explain how to solve this equation: (x-10)(x-4)=0
Answer: x = 10 OR x = 4.
Step-by-step explanation: If x = 10 or 4 then the last step of the equation will always be multiplying by 0 which equates to 0 as well.
if x = 10
(10-10)(10-4) -> (0)(6) -> 0 x 6 = 0
if x = 4
(4-10)(4-4) -> (-6)(0) -> -6 x 0 = 0
Answer:
[tex]x = 10 \: and \: 4[/tex]

12- Dana raised the high score on a video game from 300 points to 390 points. By what percentage did Dana raise the score ?
F-20%
G.23%
H.30%
J.90%
Answer:
G
Step-by-step explanation:
it is the correct answer
Answer:
Look at the image and
H. 30%
Step-by-step explanation:
[tex]\frac{100}{y}: \frac{300}{390}[/tex]
y · 300 = 100 · 390
300y = 39000
300y ÷ 300 = 39000 ÷ 300
y = 130
130% - 100% = 30%

Answer:
M R T V B K
Step-by-step explanation:
From left to right the solutions are ...
__
B: equating expressions for y
-2x = x -3 ⇒ 3 = 3x ⇒ x = 1
R: given
x = -2
V: filling in for y
4x +5(2) = 10 ⇒ x = 0
T: subtracting the first from twice the second
2(3x +y) -(-3x +2y) = 2(0) -9 ⇒ 9x = -9 ⇒ x = -1
K: adding the two equations
(2x +y) +(3x -y) = (7) +(3) ⇒ 5x = 10 ⇒ x = 2
M: equating expressions for y
x -2 = 1/3x -6 ⇒ 2/3x = -4 ⇒ x = -6
__
The solutions in order least to greatest are ...
-6 (M), -2 (R), -1 (T), 0 (V), 1 (B), 2(K)
The passcode is MRTVBK.

Additional comment
In several cases, there are variables and constants on both sides of the equal sign. The solution method is to identify the smallest variable coefficient, and add the opposite of that term. Also added at the same time is the opposite of the constant term on the other side of the equal sign. The net effect is to put the variable on one side and the constant on the other side. Then the equation is divided by the coefficient of the variable.
For example, in the first equation, -2x is the variable term with the smallest coefficient. -3 is the constant on the other side of the equation. To get from the initial expression to the next, we add 2x+3 to both sides of the equation.

You roll a standard number cube. What is the probability that you will roll an even number?
Answer:
The probability of rolling an even number would be [tex]\frac{1}{2}[/tex] or 50%.
Step-by-step explanation:
A standard number cube has 6 sides that features numbers 1 to 6 on each side. Since there are three even numbers (2, 4, 6) total on the sides of the number cube, that means the theoretical probability of rolling an even number would be [tex]\frac{3}{6}[/tex], which simplifies to [tex]\frac{1}{2}[/tex] or 50%.
Find the missing angle
A) 61.1
49.40
B) 56.10
D) 59.7
Answer:
D
Step-by-step explanation:
You have the opposite side given and the adjacent side. That means you will use the tangent.
Tan(theta) = opposite / adjacent
opposite = 6
adjacent = 3.5
Tan(theta) = 6 / 3.5
Tan(theta) = 1.714
Tan-1(1.714) = 59.74
when you get an answer over 1 from the division, you know that the angle is over 45 degrees.

Renee tossed 12 heads when tossing a coin in 10 times what is the experimental property of tossing heads
Answer:
[tex]Pr(Head) = \frac{2}{3}[/tex]
Step-by-step explanation:
The right parameters are:
[tex]Head = 12[/tex]
[tex]Toss = 18[/tex] (not 10)
Required
[tex]Pr(Head)[/tex]
The experimental probability of Head is:
[tex]Pr(Head) = \frac{Head}{Toss}[/tex]
This gives
[tex]Pr(Head) = \frac{12}{18}[/tex]
Simplify
[tex]Pr(Head) = \frac{2}{3}[/tex]

x = ___ units
Answer:
x = 20 units
Step-by-step explanation:
∆KJL is a 30° - 60° - 90° triangle which means that side opposite of 30° is x, side opposite of 60° is x√3, and side opposite of 90° is 2x.
Since side opposite of 90° is 40√2 which is 2x and x is the side opposite of 30° (JL).
2x = 40√2 → 2x ÷ 2 = 40√2 ÷ 2 → x = 20√2.
∆JML is a 45° - 45° - 90° triangle which means that sides opposite of 45° are x and 90° is x√2.
Since side JL is also the side opposite of 90° and the sides opposite of 45° are the value x,
20√2 = x√2 → 20√2 ÷ √2 = x√2 ÷ √2 → 20 = x →
x = 20.

PLEASE HELP FAST! It’s due soon
Answer:
Step-by-step explanation:
Remark
The two angles with x in them are = 90 degrees. That's because this is a right angle triangle.
Equation
x^2 + 10x + 115 = 90 Subtract 90 from both sides
Solution for x
x^2 + 10x + 115 - 90 = 0
x^2 + 10x + 25 = 0
Factor
(x + 5)(x + 5) = 0
x = - 5
Angle C
C = 10x + 115
C = 10*-5 + 115
C = -50 + 115
C = 65
Angle A (which you don't need)
x^2 = (-5)^2
x^2 = A = 25
Find BC
Cos(C) = adjacent / hypotenuse
Cos(65) =0.4226
AC = hypotenuse = 65
0.4226 = adjacent / 44 Multiply both sides by 44
44 * 0.4226 = adjacent
adjacent = 18.6 to three places.
