Answer:
1/6
Step-by-step explanation:
1/2 + 1/3 + x =1
5/6 + x = 1
x = 1 - 5/6
x = 1/6

[AB] is a diameter of center C(O, 3cm). M is a point on (C) such that MA=MB. D is the symmetric of A with respect to M.
What is the nature of triangle AMB? Justify.
Answer:
Isosceles right triangle.
Step-by-step explanation:
From the given triangle ABM,
AM ≅ MB [Given]
∠AMB is an angle subtended by the diameter AB.
By theorem, angle subtended by a diameter is always 90°.
m∠AMB = 90°
So the given triangle is a right triangle with two equal sides AM and MB.
Therefore, ΔAMB is an isosceles right triangle.
Rafael is cutting pieces of wood to make a triangular pyramid like the one shown below. The base of the pyramid is an equilateral triangle, and the faces are isosceles triangles.
Answer:
[tex]Total = 32.4in^2[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
The surface area of the pyramid
To do this, we calculate the surface area of each of the pyramid faces.
For the equilateral triangle.
[tex]Base = 4.5in[/tex]
[tex]Height = 3.9in[/tex]
The area is:
[tex]A_1 = 0.5 * Base * Height[/tex]
[tex]A_1 = 0.5 * 4.5in * 3.9in[/tex]
[tex]A_1 = 8.775in^2[/tex]
There are 3 isosceles triangles of equal dimension.
[tex]Base = 4.5in[/tex]
[tex]Height = 3.5in[/tex]
The area of one of them is:
[tex]A_2 = 0.5 * 4.5in * 3.5in[/tex]
[tex]A_2 = 7.875in^2[/tex]
For the 3, the surface area is:
[tex]3A_2 = 7.875in^2 * 3[/tex]
[tex]3A_2 = 23.625in^2\\[/tex]
The total surface area is:
[tex]Total = 8.775in^2 + 23.625in^2[/tex]
[tex]Total = 32.4in^2[/tex]

Explain (in words) what you would do to find the missing value in the equation. You do not find the missing number! Equation: ? + 59 5/8= 82 2/3 I will give Brainly whoever has the correct answer.
Answer:
The missing value = [tex]23\frac{1}{24}[/tex]
Step-by-step explanation:
Given - Equation: ? + 59 5/8= 82 2/3
To find - Explain (in words) what you would do to find the missing value in
the equation. You do not find the missing number.
Proof -
Let the missing number = x
So, the equation becomes x + [tex]59\frac{5}{8}[/tex] = [tex]82\frac{2}{3}[/tex]
⇒x = [tex]82\frac{2}{3}[/tex] - [tex]59\frac{5}{8}[/tex]
= [tex]\frac{248}{3} - \frac{477}{8}[/tex]
= [tex]\frac{1984 - 1431}{24}[/tex]
= [tex]\frac{553}{24}[/tex]
= [tex]23\frac{1}{24}[/tex]
⇒x = [tex]23\frac{1}{24}[/tex]
∴ we get
The missing value = [tex]23\frac{1}{24}[/tex]
Explanation -
Here we have given the ? with addition of number that is equation to some number.
We just have to subtract the two numbers to find the missing value , as we do above.

(-3 + 4) x 66 + -19 x 8 - 2
Answer:
-88
Step-by-step explanation:
(-3 + 4) x 66 + -19 x 8 - 2
According to PEMDAS (or GEMDAS), you start with the parenthesis. So you do the equation in the parenthesis.
-3+4= 1
Now you replace it with your answer.
1 x 66 + -19 x 8 - 2
You next do multiplication.
1*66=66
66+ -19 x 8 -2
Multiplication again
-19*8=-152
66 + -152 - 2
Now there is only addition and subtraction left so you solve left to right.
66 + -152= -86
-86-2=-88
The answer is -88

Suppose y varies directly with x and y = 25 when x = 140. What is the value of x
when y = 36?
Answer:
201.6
Step-by-step explanation:
y varies directly as x
y = kx... "k" is the constant
y = 25, x = 140
25÷140 =k × 140÷140
k = 0.17857
y = 0.17857 × x
when y = 36 what is x
36 = 0.17857 × x
x =36÷0.17857 =201.6
Select the statement that describes this expression: 32 ÷ 4 + (fraction 1 over 2 x 16) − 2. 32 times 4 plus fraction 1 over 2 times 16, then subtract 2 32 divided by 16 added to fraction 1 over 2 plus 4, then subtract 2 Half of 16 divided by 4 plus 32, then subtract 2 The quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2
Answer:
The quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2
Step-by-step explanation:
Given:
32 ÷ 4 + (fraction 1 over 2 x 16) − 2.
32/4 + (1/2 * 16) - 2
32 times 4 plus fraction 1 over 2 times 16, then subtract 2
32 divided by 16 added to fraction 1 over 2 plus 4, then subtract 2 Half of 16 divided by 4 plus 32, then subtract 2
The quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2
The statement which describes the situation is:
The quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2
Answer:
32 times 4 plus fraction 1 over 2 times 16, then subtract 2

Cost of television:
Cost of DVD player:
Answer:
TV Price: 776.25
DVD Player Price: 258.75
Step-by-step explanation:
Television:

DVD Player:
1,035/2 = 517.5
517.5/2 = 258.75
which pair of these points defines a line with a slope 2/3? A. (2, 6) and (3, 0) B. (6, 2) and 3, 0) C. (6, 2) and (0, 0) D. (2, 6) and (0, 0)
Answer:
B. (6,2) and (3,0)
Step-by-step explanation:
To find the slope the equation is [tex]\frac{y_{2-y_{1} } }{x_{2} -x_{1} }[/tex] so for (6,2) and (3,0) the equation would look like this [tex]\frac{0-2}{3-6}[/tex] which simplies down to [tex]\frac{-2}{-3}[/tex] and a negative divided by a negative is a positive so you're slope is [tex]\frac{2}{3}[/tex] and it matches the question.

Find the value of x in the isosceles triangle shown below.
Answer:
12
Step-by-step explanation:
x is the height, and we notice that this isosceles triangle is two 5-12-13 triangles put together. Therefore, x = 12
Another method. Use pythagorean theorem. x^2 + (10/2)^2 = 13^2
x^2 + 25 = 169
x^2 = 144
x = 12

Answer:
21 pieces
Step-by-step explanation:
Given that,
Length of wood needed = 233 feet
The wood comes in lengths of 11 feet.
We need to find the number of pieces samuel need to buy. It can be done as follows :
Let he needed x peices. So
[tex]x=\dfrac{233}{11}\\\\x=21.18\\\\or\\\\x=21[/tex]
