Answer:
90.6
Step-by-step explanation:
If you mean "what is the average of 94.2 and 87," that is found as follows:
94.2 + 87
------------------ = 90.6

plzz help me with the correct ans find x
Answer:
15
Step-by-step explanation:
Since, triangle ABC is the enlargement of triangle XYZ.
[tex] \therefore \triangle ABC \sim \triangle XYZ[/tex]
So, corresponding sides of both the triangles would be in proportion.
[tex] \therefore \frac{x}{6}=\frac{25}{10}[/tex]
[tex] \therefore x= \frac{6\times 25}{10}[/tex]
[tex] \therefore x =\frac{150}{10}[/tex]
[tex] \therefore x = 15[/tex]

Find measure of angles B, E, D and C and the length of BC.
Triangle ABC ~ Triangle DEF. Measure of angle A = 30 degrees and measure of angle F = 65 degrees. AB=20, DE = 35, EF= 28.
Answer:
< B = 180-30-65=85°
< E = 85°
< D = 30°
< C = 65°
BC = 20/35 × 28 = 16
Answer:
<D = 30
< C = 65
<B = <E = 85
16 = BC
Step-by-step explanation:
ABC ~ Triangle DEF
<A = <D = 30
< C = <F = 65
Since they are similar triangles
A+ C + B = 180 since the angles of a triangle = 180
30+65+B =180
95+ B = 180
<B = 180 -95 = 85
<B = <E = 85
The triangles are similar so the sides are proportional
AB BC
---- = ---------
DE EF
20 BC
---- = ---------
35 28
Using cross products
20*28 = 35 BC
Divide each side by 35
20*28/35 = 35/35 BC
16 = BC
the mean of three number is 15. if 2 of the numbers are 18 and 16 what is the third number
Answer:
The third number is 11
Step-by-step explanation:
First, you multiply 15 by 3 to get the sum(45) and then you add 18 and 16 to get 34. Lastly, you will minus 45 and 34 and your answer will be 11.
the ratio of the ages of Charlie and Kelvin is 2:3 if Charlie is 8 year old ,how old is Kelvin
Answer:
Charlie would be 11
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
Create proportional relationship to solve for Kevin's age
Let k = Kevin's age
2/3 = 8/k
Now solve for k
Cross multiply
24 = 2k
Divide both sides by 2
12 = k
If charlie is 8 then Kevin is 12

Answer:
(9, 13, 22)
Step-by-step explanation:
We can use the triangle inequality theorem to help us solve this problem. We know that the two shortest sides of a traingle added up (their sum) needs to always be greater than the longest side of the triangle. Taking that information, we can figure out that 9+13=22. 22=22, not 22>22. This means that is the right answer, hopefully that helps!

The perpendicular of a right angled triangle measures 3m, the area of the triangle 6 sq. m. What are the lengths of the other two sides of the triangle?
Answer:
the length of the other sides are
4 m and 5 m
Step-by-step explanation:
the area of right triangle = ½× b x h = 6
let b = 3m => h= 2×6/ 3 = 4m
and the hypotenuse = √3²+4²=√25= 5m
Answer:
5m and 4m
Step-by-step explanation:
(area of a right angle triangle)=1/2×b×h
let b = 3m
1/2×6×2=6×2=12/3=4m
and it's hypotenuse= 3
[tex]3 { }^{2} + 4 {}^{2} = \sqrt{25 {}^{2} } [/tex]
= 5m
A market sells cucumber for 1.20 the cost of each cucumber is the same
Answer:
Step-by-step explanation:
Let the number of cucumber = x
And the cost of the cucumber = y
Cost of the cucumber will be directly proportional to the number of cucumbers.
y ∝ x
y = kx [Here, k = proportionality constant]
Since, market sells 3 cucumbers for $1.2
1.2 = k(3)
k = 0.4
Therefore, equation for this situation will be,
y = 0.4x
Part A
If x = 1,
y = 0.4(1)
= 0.4
For x = 2,
y = 0.4(2)
= 0.8
For x = 3,
y = 0.4(3)
= 1.2
Number of cucumbers Cost($)
1 0.4
2 0.8
3 1.2
Part B
Equation representing relation between number of cucumbers and the cost will be,
y = 0.40x [Option A]
A large bag contains 16 red, 48 blue, and 16 green marbles. Each student in Mrs. Wynn's class randomly selects a marble, records the color, and then puts the marble back into the bag. Mrs. Wynn then reports the total number of red, blue, and green marbles selected by the entire class.
Which of these statements are true? Choose all that are correct.
A.
Theoretically, the probability of selecting one red marble from this bag is 0.20.
B.
If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student.
C.
If there are 30 students in the class, the total number of blue marbles selected should be about 18 but may be more or less.
D.
It is possible that every student selects a green marble.
E.
If the total number of red marbles selected is not equal to the total number of green marbles selected, then there was a mistake in selecting the marbles or recording the data.
Answer:
Find the volume of this prism.
Theoretically, the probability of selecting one red marble from this bag is 0.20.
If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student.
What are the probabilities?Probability determines how likely it is an event would happen. The chances of the event happening lie between 0 and 1.
The probability of selecting one red marble from this bag = number of red marbles / total number of marbles
16 / 80 = 0.20

Why would the answer be 3.?
Answer: Cause why not?
Step-by-step explanation:
[tex]3(4x-1)=-2x+19+8x-4[/tex]
First combine like terms:
[tex]3(4x-1)=(-2x+8x)+(19-4)\\\\3(4x-1)=6x+15[/tex]
Now distributive property
[tex](3)(4x)-(3)(1)=6x+15\\12x-3=15+6x[/tex]
Additive Property of Equality
[tex]12x-3+3=15+6x+3\\12x=18+6x[/tex]
Subtractive Property of Equality
[tex]12x-6x=18+6x-6x\\6x=18[/tex]
And finally Division Property of Equality
[tex]\frac{6x}{6} =\frac{18}{6} \\x=3[/tex]
(5x-3)=(3x+27) I dont understand
Answer:
x = 15
Step-by-step explanation:
(5x-3)=(3x+27)
Subtract 3x from each side
(5x-3x-3)=(3x-3x+27)
2x-3 = 27
Add 3 to each side
2x-3+3 = 27+3
2x= 30
Divide by 2
2x/2 = 30/2
x = 15
If f(1) = 1 and f(n + 1) = 5f(n) + 3 then find the value of f(4).
Answer:
218
Step-by-step explanation:
Because we need f(n) to calculate f(n+1), we have to calculate our values one step at a time. Starting with f(1) = 1,
f(2) = 5(f(1)) + 3 = 5(1) + 3 = 5+3 = 8
f(3) = 5(8) + 3 = 40 + 3 = 43
f(4) = 5(43) + 3 = 215 + 3 = 218
