Answer:
A, E
Step-by-step explanation:
The mean of the pizza truck:
(400 + 800 + 1000 + 1000)/4 = 800
The mean of the burger truck:
(800 + 700 + 900 + 800)/4 = 800
A is correct, which voids answer C
The median of the pizza truck:
400, 800, 1000, 1000
\ /
900
The median of the burger truck
700, 800, 800, 900
800
900>800 so E is correct, voiding all other answers

Find the area of a circle with radius,
r
= 5.99m.
Give your answer rounded to 2 DP.
Answer: 112.72
Step-by-step explanation: We know that the formula for area of a circle is pi*r^2. Now we plug in the values. pi*5.99^2. Next we get rid of the exponent. 5.99*5.99 = 35.8801. Now we have pi*35.8801. Now if you are gonna use actual pi for this your answer would be 112.72065857. Round it to 2 decimal points and you have 112.72 . If you do 35.8801*3.14=112.663514 -> Round this and you have 112.66. So any of them would actually work but I would stick with 112.72.

Find the area of each triangle. Round to the nearest tenth.
5
40°
3
Answer:
D
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] ab sinC ( a, b are the sides and C the angle between them ) , then
A = [tex]\frac{1}{2}[/tex] × 5 × 3 × sin40° = 7.5 × sin40° ≈ 4.8 units² ( to nearest tenth )

If tan = 4/11 then what will tan(90 - ) be? Please show work.
Answer:
Tan.
Step-by-step explanation:
First way;
Tan (90-θ )=Cot θ Tan (90+θ )= -Cot θ
1st explanation, QUOTATIONS!
"tan90∘ is undefined because you can't divide 1 by nothing. Nothing multiplied by 0 will give an answer of 1 , so the answer is undefined."
2nd explanation, QUOTATIONS!
"That's undefined because as you approach 90° from either direction, tan approaches positive or negative infinity. cot(90°) hence approaches 1/infinity (either positive or negative) which is just 0."

Are 4(a - 3) and 4a - 7 equivalent expressions?
Answer:
Yes
Step-by-step explanation:
Given expression: 3x+9
Take 3 outside from the expression, we get,
= 3(x+3), which is called the equivalent expression
Answer:
No
Step-by-step
We have to multiply the 4 by both the a and the 3 since there a parenthesis around them. This would of course be distributive property. Since you don't know what a is, it would just be 4a and since we can multiply 4 and 3 that would be 12. So, 4(a - 3) is equivalent to 4a - 12.
8/15(-2/3) whats the answer?
Answer:
-0.8 is the correct answer of this question
Answer:
-16/45
Step-by-step explanation:
When you mulitply these two fractions together it's best to muliteply them by the number across so therefore 8x-2= -16 and 15x3= 45 which you end up with -16/45
Refer to the figure to complete the following item.
Given: PB tangent PV, PU secants
angle1=30 and mSTarc= 20, then mVUarc=___
Answer:
Answer: 80°
Step-by-step explanation:
Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference of the measures of the intercepted arcs.
In the given diagram,
Chord VS and chord UT are intersecting externally,
Also, ∠SPT is the angle formed by the intersection of these chords.
Thus, by the above property,
⇒ Measurement of the arc VU= 80°.
Answer:
80 is the correct answer

A line passes through the points (3, 9) and (0, 3). What is its equation in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
[tex] y = 2x + 3 [/tex]
Step-by-step explanation:
Given :-
Two points are given to us .The points are (3,9) and (0,3) .And we need to find the equation in slope intercept form. So here we can find the equation of the line using two point form , as ,
[tex]\implies y - y_1 = \dfrac{ y_2-y_1}{x_2-x_1}( x - x_1) [/tex]
Now plug in the respective values ,[tex]\implies y - 9 = \dfrac{ 3-9}{0-3}( x - 3) \\\\\implies y - 9 =\dfrac{-6}{-3}( x - 3 ) \\\\\implies y - 9 = 2( x - 3 ) \\\\\implies y - 9 = 2x - 6 \\\\\implies y = 2x - 6 +9 \\\\\implies \boxed{ y = 2x + 3 }[/tex]
Hence the equation in slope intercept form is y = 2x + 3.
find the surface area of the prism
Answer:
740 m²Step-by-step explanation:
The surface area of a prism is a sum of areas of all of its faces
2×(¹/₂×16×15) + 2×(17×10) + 16×10 = 240 + 340 + 160 = 740 m²
(please explain clearly, I am very tired) Find the surface area of the composite figure.
Answer:
644
Step-by-step explanation:
SA=[2×(5×20 + 5×6 + 20×6)] +
[2×(4×12 + 4×6 + 12×6)] -
[ 2× 12×6]
= [2×(250)]+[2×(144)] - [144]
= 500+288-144
= 644 cm²

ΔABC has been flipped over, so we have a reflexion using line BC
So, the answer to 1. is line BC
The result is ΔE'F'D'
Now ΔE'F'D' is moved 4 units to the right. That is the answer to 2.
The result is ΔE"F"D"
Finally ΔE"F"D" is moved 1 unit down. That is the answer to 3.
The final result is ΔEFD
Ok. Did that help you?
