Answer:
b = 8.89, c = 11.96 and m∠B = 48°
Step-by-step explanation:
From the given triangle ABC,
We will apply sine ratio for angle A,
sin(A) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(42)° = [tex]\frac{BC}{AB}[/tex]
sin(42)° = [tex]\frac{8}{AB}[/tex]
AB = [tex]\frac{8}{\text{sin}(42)}[/tex]
AB = 11.96
c = 11.96
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
42° + m∠B + 90° = 180°
m∠B = 180 - 132
m∠B = 48°
By cosine ratio of angle A,
cos(A) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(42)° = [tex]\frac{AC}{AB}[/tex]
AC = AB.cos(42)°
AC = (11.96)cos(42)°
AC = 8.89
b = 8.89

Tom earned a total of $88 last month. He earned $45 walking his neighbors dog and b dollars for babysitting his younger brother. Which equation and solution represents the total amount Tom earned babysitting?
Best gets Brainlest
Answer:
A. 45 + b = 88, so b = $43
Step-by-step explanation:
We know that he's earned $45 dollars, plus b dollars for babysitting. This gives us the first part of the equation (45 + b). The total amount he earned was $88, so 45 + b = 88.
Then, you can solve it.
45 + b = 88
-45 -45
0 + b = 43
b = 43
This means he earned $43 babysitting his younger brother.
Hope this helps :)

Answer/Step-by-step explanation:
Decompose each shape, find the volume of each cuboid, and add both volumes you get together.
Recall: volume of cuboid = L*W*H
4. Volume of cuboid 1: L*W*H = 12*10*4 = 480 ft³
Volume of cuboid 2: L*W*H = 12*3*5 = 180 ft³
Volume of the shape = 480 + 180 = 660 in.³
5. Volume of cuboid 1: L*W*H = 11*2*5 = 110 yd³
Volume of cuboid 2: L*W*H = 10*4*2 = 80 yd³
Volume of the shape = 110 + 80 = 190 yd³
6. Volume of cuboid 1: L*W*H = 8*3*2 = 48 in.³
Volume of cuboid 2: L*W*H = 14*2*3 = 84 in.³
Volume of the shape = 48 + 84 = 132 in.³
7. Volume of cuboid 1: L*W*H = 5*3*2 = 30 yd³
Volume of cuboid 2: L*W*H = 6*2*5 = 60 yd³
Volume of the shape = 30 + 60 = 90 yd³
8. Volume of cuboid 1: L*W*H = 12*2*18 = 432 in.³
Volume of cuboid 2: L*W*H = 18*5*6 = 540 in.³
Volume of the shape = 432 + 540 = 972 in.³
9. Volume of cuboid 1: L*W*H = 13*11*4 = 572 ft³
Volume of cuboid 2: L*W*H = 13*6*7 = 546 ft³
Volume of the shape = 572 + 546 = 1,118 ft³

A company that sold fish for an aquarium had a special one weekend on tetras and angel fish. The store sold a total of 110 of those types of fish over the weekend. The tetras each sold for $0.40 and the angel fish each sold for $1.20. If they made a total of $80 in selling those fish, how many tetras did they sell?
Answer: They sold 65 tetras.
Step-by-step explanation:
Let x= Number of tetras
y= Number of angel fish.
As per given,
x+y= 110 (i)
0.40x+1.20y=80 (ii)
Multiply 2.5 on both sides of (ii), we get
x+3y=200 (iii)
Eliminate (i) from (iii)
[tex]2y=90\\\\\Rightarrow y=45[/tex]
Put value of y in (i)
[tex]x+45=110\Rightarrow x=65[/tex]
Hence, they sold 65 tetras.

Answer:
Width = x
Length = 3x+4
Step-by-step explanation:
Equations
Let's call x = width of the rectangle.
We know the length is 4 feet longer than 3 times the width, thus:
length = 3x + 4
Dimensions of the rectangle:
Width = x
Length = 3x+4

A circle has a radius of 48 millimeters.
What is the length of the arc intercepted by a central angle that measures 3π/4 radians?
Express the answer in terms of π .
Enter your answer in mm in the box.
Answer:
Arc length, S...is given by
S = r (theta in radians)
So
S = 28 (3π/4) = 28 (3/4)*π = [ 21 π ] inches
Step-by-step explanation:
The length of the arc intercepted by a central angle that measures 3π/4 radians will be 113.04 millimeters.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The central angle = 3π/4
And, A circle has a radius of 48 millimeters.
Now,
We know that in circle;
Arc = Radius × Angle
Substitute all the values, we get;
⇒ Arc = 48 × 3π/4
⇒ Arc = 3 × 12 × 3.14
⇒ Arc = 113.04 millimeters
Thus, The length of the arc will be;
Arc = 113.04 millimeters
