Answer:
B
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{?}{6}[/tex] = [tex]\frac{18}{12}[/tex] ( cross- multiply )
12 ? = 108 ( divide both sides by 12 )
? = 9 → B
Steak cost $3.85 per pound if you buy a 3 pound steak and pay for it with a $20 bill how much change will you get ?
Answer:
$ 8.45
Step-by-step explanation:
3.85 * 3 = 11.55
20 - 11.55 = 8.45
The angles in a triangle are in the ratio 5 : 3 : 1.
a) What type of triangle is it?
b) Calculate the biggest angle of this triangle.
Answer:
Step-by-step explanation:
It is an obtuse triangle because one angle (5) takes up more than the sum of the other two (3+1=4).
The angles are:
5+3+1 = 9
Each angles is
5/9 * 180 = 100°
3/9 * 180 = 60°
1/9 * 180 = 20°
Total = 100+60+20 = 180 degrees.

Find the measure of WX
Answer:
WX = 66°
Step-by-step explanation:
The inscribed angle WXY is half the measure of its intercepted arc, then
arc WY = 2 × 57° = 114°
XY is a diameter of the circle, so
arc XY = 180°
Thus
arc WX = 360° - (180 + 114)° = 360° - 294° = 66°

You roll a die 42 times. The table shows the results. Find the experimental probability of rolling each number. Write each probability as a fraction in simplest form. For which number is the experimental probability of rolling the number the same as the theoretical probability?
p(one)=
p(two)=
p(three)=
p(four)=
p(five)=
p(six)=
no links, please
There are 6 numbers in a die.
So, theoretical probability of each no. = 1/6
P(1) = 7/42 = 1/6
P(2)= 6/42 =1/7
P(3) = 14/42= 1/3
P(4)= 4/42=2/21
P(5)= 6/42= 1/7
P(6)= 5/42
For no. 1 experimental probability of rolling the number the same as the theoretical probability

Answer:
148cm²
Step-by-step explanation:
With the first frontal face of the cuboid, you have length 6 cm whilst the height remains 5 cm.
Find the area of this face and multiply the result by 2, as there are two of these faces (front and back)
6 x 5 = 30 cm²
30 x 2 = 60cm²
Do the same with the top face and bottom face, adding this with the side faces
4 x 6 = 24cm²
24 x 2 = 48cm²
4 x 5 = 20cm² x 2 = 40 cm²
40 + 48 + 60 = 148 cm²
T.S.A = 148cm²

Answer:
D. The trench has become shallower because -32 is farther from 0 on a number line than -27
Answer: D
Step-by-step explanation: -27 is closer to zero than -32. Since these numbers were negative and the depth of the trench went from -32 to -27, we can assume that the trench had gotten more shallow.

Suppose a male and a female of a certain species of animal were taken to a deserted island. The population of this species quadruples (multiplies by 4) every year. Assume that the animals have an abundant food supply and that there are no predators on the island.
What is an equation that can be used to model the population of the species?
Complete the equation below
f(n) = _______________
Use n as your variable.
Use the ^ symbol to represent an exponent.
For example: 52 should be typed as 5^2
Answer:
f(n) = 2 * 4^n
Step-by-step explanation:
The initial population = a male and a female = 2
The population quadruple every year, this means, a multiplication by 4 every year.
Hence, we have :
f(n) = (Initial population * multiple^years)
f(n) = 2 * 4^n
What is the range of the function pictured below?

. Determine f(4.5) for the function f(x) = 3x - 5 *
Algebra
f(4.5)=8.5
Plug in x as 4.5 and multiply it with 3. Then subtract 5 from the remaining result.
Answer:
f(4.5) = 8.5
Step-by-step explanation:
f(4.5) = 3x - 5
f(4.5) = 3(4.5) - 5
f(4.5) = 13.5 - 5
f(4.5) = 8.5
Hope that helped! You have to substitute x with 4.5 and then solve.

Find the diameter of the circle. Assume the leg of the triangle is tangent to the circle. Round any decimals to the nearest tenth.
Answer:
8.7 units
Step-by-step explanation:
Given is a right angled triangle (because the segment with 5 units length is tangent to circle. Tangent is perpendicular to RADIUS or diameter)
Let the length of the diameter be d units
By Pythagoras Theorem:
[tex]d = \sqrt{ {10}^{2} - {5}^{2} } \\ = \sqrt{100 - 25} \\ = \sqrt{75} \\ = 8.66025404 \\ = 8.7 \: units[/tex]

Answer:
[tex]9600 \: {ft}^{2} \\ [/tex]
Step-by-step explanation:
Area of front rectangle -
= 2 ( length × breadth )
= 2 ( 40 × 30 )
= 2 ( 1200)
[tex] = {2400 \: ft}^{2} \\ [/tex]
Area of other rectangles -
= 4 ( length × breadth )
= 4 ( 60 × 30 )
= 4 ( 1800)
[tex] = 7200 \: {ft}^{2} \\ [/tex]
Surface area of the rectangular prism
[tex] = {2400 \: ft}^{2} + {7200 \: ft}^{2} \\ = {9600 \: ft}^{2} \\ [/tex]
