Multiply 6 by both factors in the parentheses, in this case, a and 10.
6*a = 6a
6*10 = 60

Fraction of a whole: When we divide a whole into equal parts, each part is a fraction of the whole.
a fraction has 2 parts
The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken. The number below the line is called the denominator.

Step-by-step explanation:
Given
[tex]x: \dfrac7{10}m, \dfrac12m,38cm[/tex]
See comment
Required
The total height
This is calculated as:
[tex]Total = \sum x[/tex]
So, we have:
[tex]Total = \dfrac7{10}m+ \dfrac12m+38cm[/tex]
Express m as cm
[tex]Total = \dfrac7{10}cm * 100+ \dfrac12cm * 100+38cm[/tex]
[tex]Total = 70cm + 50cm + 38cm[/tex]
Take LCM

what is sqrt 2x-3 = sqrt 3x-9
Answers
Answer:
x=6
Step-by-step explanation:
sqrt (2x-3) = sqrt (3x-9)
Square each side
(sqrt (2x-3))^2 = (sqrt (3x-9))^2
2x-3 = 3x-9
Subtract 2x from each side
2x-3-2x = 3x-2x-9
-3 = x-9
Add 9 to each side
-3+9 = x-9+9
6 =x
Check solution
sqrt (2*6-3) = sqrt (3*6-9)
sqrt (9) = sqrt (9)
3=3
Solution is valid
sqrt (2x-3) = sqrt (3x-9)
Square each side
(sqrt (2x-3))^2 = (sqrt (3x-9))^2
2x-3 = 3x-9
Subtract 2x from each side
2x-3-2x = 3x-2x-9
-3 = x-9
Add 9 to each side
-3+9 = x-9+9
6 =x
sqrt (2*6-3) = sqrt (3*6-9)
sqrt (9) = sqrt (9)
3=3
Therefore ans x = 6

Step-by-step explanation:
Given the sample data :
The estimate of the population mean from the sample data is given as :
Mean = ΣX / n
Mean = (12+67+25+62+33+38+34+47+53+16+11+97+46+32+62+27) / 16
Mean = 662 / 16

Answer:
15/17Step-by-step explanation:
sine = opposite / hypotenusesin A = BC/ACsin A = 15/17Verify that the indicated function y = ϕ(x) is an explicit solution of the given first-order differential equation. (y − x)y' = y − x + 18; y = x + 6 √(x + 4)
When y = x + 6√(x + 4) y'=_________
Thus in terms of x, (y-x)y'=________
y-x+18=________
Answers
If y = x + 6√(x + 4), then
y' = 1 + 3/√(x + 4)
Substituting y and y' into the DE gives
(y - x) y' = (x + 6√(x + 4) - x) (1 + 3/√(x + 4))
… = 6√(x + 4) (1 + 3/√(x + 4))
… = 6√(x + 4) + 18
on the left side, while on the right you get
y - x + 18 = x + 6√(x + 4) - x + 18
… = 6√(x + 4) + 18
so both sides match and the given function is indeed a solution to the DE.
A survey showed that out of 600 surgery patients at ABC Medical Center, 8% of them had eye surgery. Find the number of patients that had eye surgery.
Answers
Answer:
48
Step-by-step explanation:
.08x600=48
Answer:
Step-by-step explanation:
total patients = 600
% of patients had eye surgery = 8%
Number of patients that had eye surgery ?= x
% of pt that had eye surgery = no. of pt that had surgery/ total number of pt
8/100= x/600
x=(8x600) /100
x= 4800/100
x= 48
Number of patients that had eye surgery were 48

The radius of the sector is 15 cm.
Calculate the total surface area of the prism.
Answers
Answer:

Step-by-step explanation:
cross section = 2*15*5+2*(25/360)*15*15*pi+5*(25/360)*2*pi*15
= 280.8997
Total surface area of prism is 280.890cm²
What is surface area?A solid object's surface area is a measurement of the overall space that the object's surface takes up, and it is always expressed in square units.
The term "surface area" is sometimes used to refer to "total surface area".
Find the sector angle in radians
α = 25× (π/180)
α = (25π)/(180) rad
Find the area of the prism:
A = 2×15×5 + 15×15×α + 5×15×α
A = 150 + 15×15×(25π)/(180) + 5×15×(25π)/(180)
A = 280.890cm²

A group of 6 children and 6 adults are going to the zoo. Child tickets cost $10, and adult tickets cost $14. How much will the zoo tickets cost in all?
Answers
Answer:
i believe it'll cost 200 dollars
This is because you have 6 children’s tickets each for $10, so you take the 6x10 which gives you $60. Then you have 6 adult tickets which cost $14, so you take 6x14 which equals $84. When added together that is $144!

During a 1966 Tabiona High School track meet, Levere ran the 100 yard dash in
10.63 seconds. Ross took second with a time of 10.98 seconds.
a. Levere’s time was _______% shorter than Ross’.
b. Ross’ time was _______% longer than Levere’s.
c. Levere’s time was _______% of Ross’.
Answers
Answer:
a) 3.19
b) 3.29
c) 96.81
Step-by-step explanation:
Question a:
Levere's: 10.63s
Ross: 10.98s
10.98 - 10.63 = 0.35s shorter than 10.98s, so:
0.35*100%/10.98 = 3.19% shorter.
Question b:
35s longer than 10.63s, so:
0.35*100%/10.63 = 3.29% longer.
Question c:
3.19% shorter, so 100 - 3.19 = 96.81% of Ross.

Explanation:
Let's say the triangle has sides a,b,c such that a < b < c
a = 5 = short legb = unknown long legc = b+1 = hypotenuseUse the pythagorean theorem to solve for b
[tex]a^2 + b^2 = c^2\\\\5^2 + b^2 = (b+1)^2\\\\25 + b^2 = b^2+2b+1\\\\25 + b^2-b^2-2b-1 = 0\\\\-2b+24 = 0\\\\-2b = -24\\\\b = -24/(-2)\\\\b = 12[/tex]
The longer leg is 12 meters in length.
c = b+1 = 12+1 = 13
The hypotenuse is 13 meters long.
We have a 5-12-13 right triangle.
