[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.

Samuel needs 233 feet of wood to build a fence.The wood comes in lengths of 11 feet. How many prices will samuel need to buy?
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]
So, he will need approx 21 peices.
Parallelogram Q T S R is shown. Sides Q T and R S are parallel, and sides Q R and T S are parallel. Angle Q is (9 x minus 6) degrees and angle R is (8 x minus 1) degrees. Devin started the work shown to solve for the unknown angle measures. 8x – 1 + 9x – 6 = 180 17x – 7 = 180 17x = 187 What are the measures of angles Q and R? m∠Q = ° m∠R = °
Answer:
m<Q = 93 degrees
m<R = 87 degrees
Step-by-step explanation:
Given the following angles;
m<Q = 9x-6
m<R = 8x-1
Looking at Devin's work, we will see that he the sum of both angles is 180 degrees
Hence m<Q + m<R = 180
9x - 6 + 8x - 1 = 180
9x+8x-6-1 = 180
17x - 7 = 180
17x = 180 + 7
17x = 187
x = 187/17
x = 11
Get m<Q
m<Q = 9x - 6
m<Q = 9(11) - 6
m<Q = 99 - 6
m<Q = 93 degrees
Get m<R
m<R = 180 - m<Q
m<R = 180 - 93
m<R = 87degrees
Answer:
93 and 87

A ladder is 51 inches tall. How tall is it in feet and inches?
Answer:
4 feet and 3 inches
Step-by-step explanation:
The measure of ladder in feet is 4.15.
Given that, a ladder is 51 inches tall.
Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
We know that, 1 feet = 12 inches
So, in inches = 51/12
= 4.25 feet
Therefore, the measure of ladder in feet is 4.15.

(-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

Answer:
900<x<1100
Step-by-step explanation:
The third side must be greater than the difference of the other two sides
10000- 1000 < 10x
9000< 10x
Divide by 10
9000/10 < x
900 < x
The third side must be smaller than the sum of the other two sides
10000+1000 > 10x
11000>10x
Divide by 10
11000/10>10x/10
1100>x
900<x<1100

Scientists are studying a bacteria sample. The function f of x equals 256. 1.15 to the x. gives the number of bacteria in the sample at the end of x days. Which statement is the best interpretation of one of the values in this function?
Answer:
the number of bacteria increases at a rate of 15% each day
Step-by-step explanation:
Given the function :
f(x) = 256(1.15)^x
The function represents an exponential growth function ; comparing the equation with the general form of an exponential growth function :
f(x) = A(1 + r)^t
A = the initial value of the population, = 256
(1 + r),; r = growth rate
Therefore, to solve for r ;
1 + r = 1.15
r = 1.15 - 1 ; r = 0.15
Hence, growth rate = 0.15 = 0.15 * 100% = 15%
Hence, the number of bacteria increases at a rate of 15% each day

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

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]
Circle the smaller number: 0.123 0.13. Explain how to use the grids below to support your answer.
Answer: The smallest number is 0.123
Step-by-step explanation:
We want to find the smallest number between:
0.123 and 0.13
To do it, we first need to look at the largest digit of each number and see which one is larger.
In both cases we can see that the largest digit for both numbers is the first digit after the decimal point.
For both numbers this digit is 1, so we can't conclude nothing yet.
Now we need to look at the next digit.
For 0.123, the second digit is 2.
For 0.13 the second digit is 3.
Then the second digit is larger for 0.13, this means that 0.123 is the smallest number.
I can not explain you how to use the grids below because i can not see them in the question.

What is the distance between points S and U if S is 2, 1 and U is 6, 8
Round to the nearest tenth of a unit.
A. 3.3 units
B. 6.4 units
C. 8.1 units
D. 12.0 units
The distance formula is:
D = sqrt((x2-x1)^2 + (y2-y1)^2)
D= sqrt ((6-2)^2 + (8-1)^2)
D = sqrt(4^2 + 7^2)
D = sqrt( 16 + 49)
D = sqrt(65)
D = 8.06
Rounded to the beat tenth = 8.1 units.
The answer is C. 8.1 units
Answer:
C
Step-by-step explanation:
S has coordinates (2 , 1) and U has coordinates (6, 8) . Computing the SU vector gives us (4 , 7)
taking the distance formula : sqrt(4^2 +7^2)
= sqrt(65) = 8.1 which is answer C
