The amount that Sam get (the share of Sam) is £120
What is ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
Suppose that we've got a = 6, and b= 4, then:
[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Same thing happens for 3 quantities and more such quantities.
So if its given that Oli, Sam, and Tim's share (total £360) are in the ratio 3:2:1, that means some common factor (lets call it 'x') must be cancelled off as 3+2+1 don't equate to 360.
So, we have:
Oli's share = 3xSam's share = 2xTim's share = 1x = xTheir total evaluates to 360 (in euros).
(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)
Thus, we get:
[tex]3x + 2x + x = 360\\(3+2+1)x = 360\\6x = 360\\\\\text{Dividing both the sides by 6}\\\\\dfrac{6x}{6} = \dfrac{360}{6}\\\\x = 60[/tex]
Thus, we get:
Oli's share = 3x = 3×(60) = £180Sam's share = 2x = 2×(60) = £120Tim's share = 1x = x = £60Thus, the amount that Sam get (the share of Sam) is £120

7853.98mm
Step-by-step explanation:
Circumference is pi times diameter so the diameter is 100 millimeters
Diameter is 2 times the radius so the radius is 50 millimeters
Area is pi times the radius squared so the area is about 7853.98 millimeters squared
Answer:
A = 795.77
Step-by-step explanation:
Using the formulas
A=πr2
C=2πr
Solving forA
A=C2
4π=1002
4·π≈795.77472

please answer problem 24 THANK YOU
Answer:
PART A. look belowPART B. slope=-15, y-intercept=375Step-by-step explanation:
PART A. Graph the linear equation
- Look at the Graph below as an attachment
PART B. Interpret the slope and the y-intercept
- The slope-intercept form in the linear equation is: y=mx+b
m=slopeb=y-interceptSolve
y=mx+b
y=-15x+375
slope=-15
y-intercept=375

f(x)=
Answer:
f
f(x) =-3/4x +2
Step-by-step explanation:
You have points (0,2) and (-4,5) Soo the slope is 5-2/-4-0 = 3/-4
Then f(x) = mx+b. So f(x) = -3/4x + 2 because the y intercept is (0,2).
Answer:
f(x)= -x+2
Step-by-step explanation:
Looking at the graph gives us this information:
SLOPE
you can see that for every 1 unit over, it goes one unit down.
slope = rise / run which would be -1/1 which is also just -1
INTERCEPT
the y intercept is 2
equations are typically written in y=mx+b form (where m is the slope and b is the intercept)
so we have y = -1x +2
you don't need to write the 1 because -1x is the same as -x
sof(x)= -x+2
5x - 7
3x + 1
11x – 4

In AMNO, m = 150 inches, n = 550 inches and o=630 inches. Find the measure of ZO
to the nearest 10th of a degree.
The measure of ∠O is, 115.8°.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
In ΔMNO, m = 150 inches, n = 550 inches and o=630 inches.
Now, We know that;
⇒ cos O = m² + n² - o² / 2mn
Substitute all the values, we get;
⇒ cos O = 150² + 550² - 630² / (2 × 150 × 550)
⇒ cos O = - 0.4357
⇒ ∠ O = 115.8°
Thus, The measure of ∠O = 115.8°

Paula runs a day care center. Of the last 16 children to enroll at
the day care center, 8 of them have been babies. What is the
experimental probability that the next child to enroll will be a
baby?
Write your answer as a decimal rounded to the nearest tenth.
Answer:
0.5
Step-by-step explanation:
P(event) = number of times event occurs/ total number of trials
Hi, You are the person I answered last time!
P(event) = 8/16
8/16 simplified is equaled to 1/2.
1/2 is equaled to 0.5
Again, I'm pretty sure this is right because it says experimental probability... I hope this helps!
Show work for brainly
Answer:
There are 6 cakes.
Each person can eat 1/2 of a cake.
You need to find how many times you can split 6 cakes into 1/2 of a cake.
Obviously, division is the way to go.
6 ÷ 1/2
When dividing by a fraction, you need to turn both parts into fractions.
6/1 ÷ 1/2
Now you skip the first part.
Focus on 1/2
Flip the fraction: 2/1
Now multiply the two fractions together
6/1 *2/1 = 12/1
Therefore 12 people can be at the party.
PLEASE BRAINLIEST
I love the killua profile pic
Answer: 12 people
Step-by-step explanation:
6 total cakes ; everyone eats [tex]\frac{1}{2}[/tex]
6 people would eat 3 cakes because [tex]\frac{1}{2}[/tex] × 6 people = 3 cakes.
However, 12 people would eat 6 cakes because [tex]\frac{1}{2}[/tex] × 12 people = 6 cakes.

Two supplementary angles that are 4x and 5x what is the value of x
Answer:
x = 20
Step-by-step explanation:
4x + 5x = 9x
9x = 180 (supplementary angles add up to 180 degrees)
Divide 180/9 = 20
Answer:
x = 20.
Step-by-step explanation:
Supplementary angles sum to 180, so:
4x + 5x = 180
9x = 180
x = 20.
What is the measure of 1?
A. 15
B. 35
С. 37
D. 79
Answer:
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
I am not sure about it, but maybe 15.
<1 = (2x + 5) and <2 = (3x - 10)
<1 = (2 × 15 + 5 ) and <2 = (3 × 15 - 10)
<1 = (30 + 5) and <2 = (45 - 10)
<1 = 35 and <2 = 35
