In triangle ABC, m∠A=(6x+9)∘, m∠B=(x−8)∘, and the exterior angle at C is 141∘.
What is the measure of angle B?
12∘
20∘
141∘
129∘
Answers
Answer:
12°
Step-by-step explanation:
Let's start with the easy first.
We know that m∠C is 39° because together ∠C and the exterior angle equal 180°. And 180 - 141 = 39.
Now, we can use this to find the remaining two angles.
180° - 39° = 141°
So, this means that we can set up m∠A + m∠B = 141°.
6x + 9 + x - 8 = 141
7x + 1 = 141
7x = 140
x = 20
Finally, we can plug in for our x value and find m∠B.
m∠B = x - 8
m∠B = 20 - 8
m∠B = 12°

Answers
Answer:
a_{n} = a_{1} + (n-1)d
a_n = the nᵗʰ term in the sequence
a_1 = the first term in the sequence
d = the common difference between terms
The general term of an arithmetic sequence can be written in terms of its first term a1, common difference d, and index n as follows: an=a1+(n−1)d. ... The nth partial sum of an arithmetic sequence can be calculated using the first and last terms as follows: Sn=n(a1+an)2.

Use the net to find the surface area of the prism.
96 in2
12 in2
24 in2
84 in2
Answers
Answer:
a. 96 in²
Step-by-step explanation:
The surface area of the prism = the sum of the area of each part of the net shown
✔️Area of the 2 equal triangles = 2(½*b*h)
b = 4 in
h = 3 in
Area of the two triangles = 2(½*4*3) = 12 in²
✔️Area of the rectangle 1 with the following dimensions:
L = 7 in
W = 3 in
Area = L*W = 7*3 = 21 in²
✔️Area of the rectangle 2 with the following dimensions:
L = 7 in
W = 4 in
Area = L*W = 7*4 = 28 in²
✔️Area of the rectangle 3 with the following dimensions:
L = 7 in
W = 5 in
Area = L*W = 7*5 = 35 in²
✅Surface area of the prism = 12 + 21 + 28 + 35 = 96 in²

Answers
Answer:
(a)2 1/4
(b)1 1/2
(c)1 1/18
(d)5 7/12
Step-by-step explanation:
(a) 11/3 - 17/12 = 44/12 - 17/12 = 27/12 = 9/4 = 2 1/4
(b) 33/10 - 18/10 = 15/10 = 3/2 = 1 1/2
(c) 41/9 - 7/2 = 82/18 - 63/18 = 19/18 = 1 1/18
(d) 47/6 - 9/4 = 94/12 - 27/12 = 67/12 = 5 7/12

3 8/12 - 1 5/12 = 2 3/12 = 2 1/4
b) 3 3/10 - 1 4/5 we’ll convert to 10ths by multiplying the numerator and denominator of the second mixed number by two.
3 3/10 - 1 8/10
Now we need to borrow from the three wholes to create more tenths
2 13/10 - 1 8/10 = 1 5/10 = 1 1/2
Or you can convert the first one to 33/10, and the second one to 9/5, which becomes 18/10.
33/10 - 18/10 = 15/10 = 1 1/2
Do whichever one makes more sense to your brain.
c) 4 5/9 - 3 1/2 we will convert both to 18ths.
4 10/18 - 3 9/18 = 1 1/18
d) 7 5/6 - 2 1/4 we will convert both to 12ths.
7 10/12 - 2 3/12 = 5 7/12

Write the equation of the circle with the given information.
Center: (2,8)
Radius: 3
Answers
Answer:
(x - 2)² + (y - 8)² = 9
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
Here (h, k ) = (2, 8 ) and r = 3 , then
(x - 2)² + (y - 8)² = 3² , that is
(x - 2)² + (y - 8)² = 9

b Find its capacity in kilolitres.
Answers
Answer:
77 cm^3
22 m^3
22 kl^3
Step-by-step explanation:
volume of a cylinder = nr^2h
n = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
1. Radius = 3.5 / 2 = 1.75
Volume = (22/7) x (8) x 1.75^2 = 77 cm^3
2. radius = 2/2 = 1m
Volume = (22/7) x (7) x 1^2 = 22 cm^3
1 meter = 1 kilolitre
capacity = volume
capacity = 22 kl^3
Daniel is constructing boxes in the shape of triangular prism. How much cardboard is needed to make each box
Answers
Answer:
Area of cardboard required = 468 cm²
Step-by-step explanation:
Area of the cardboard required = Surface area of the triangular prism
Surface area of the triangular prism = Area of the lateral sides + Area of the triangular sides
Area of the one triangular side = [tex]\frac{1}{2}(\text{Base)}(\text{Height})[/tex]
= [tex]\frac{1}{2}(12)(9)[/tex]
= 54 cm²
Area of lateral sides = Perimeter of the triangular base × Height
Perimeter of the triangular base = 9 + 12 + 15
= 36 cm
Now area of the lateral sides = (36) × 10
= 360 cm²
Surface area of the prism = 360 + 2(54)
= 360 + 108
= 468 cm²
Therefore, area of cardboard required for each box = 468 cm²

The sum of two numbers is 70. One number is ten more than twice the other number. Find the numbers.
Answers
9514 1404 393
Answer:
20, 50
Step-by-step explanation:
Let x and y represent the two numbers.
x + y = 70 . . . . . . their sum is 70
2x +10 = y . . . . . . one is 10 more than twice the other
Using the second equation to substitute for y in the first equation, we have ...
x + (2x +10) = 70
3x = 60 . . . . . . . . . subtract 10
x = 20 . . . . . . . . . divide by 3
y = 70 -20 = 50 . . . find the other number
The two numbers are 20 and 50.
