Regular quadrilateral pyramid with base edge b=55mm and lateral edge l=7 cm. Find the sum of all edges

Answers

Answer 1

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?​

Answers

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 ?​

Answers

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

Answers

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:

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

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?

Answers

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

Answers

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.

x = ___ units

Answers

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

Answers

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.
