Answer:
The third time = 11.64 seconds
Step-by-step explanation:
Let the average time be x
The average of a set of numbers is the sum of the numbers divided by the number of terms. In this case:
Average = (10.84 + 13.52 + x) ÷ 3 = 12.0
[tex]\frac{10.84\ + 13.52\ + x}{3}= 12.0\\\frac{24.36\ +\ x}{3} = 12.0\\cross-multiplying\\24.36\ +\ x = 3 \times 12.0\\24.36\ +\ x = 36\\x = 36 - 24.36\\x = 11.64\ seconds[/tex]

Simplify the ratio 18:24:42
Answer:
for simplifying these ratio
we have to first
find out GCF of all
which is 6
now divide each of them with 6
then we will get. 3:4:7
hope it will help
Answer:
3:4:7
Step-by-step explanation:
First find HCF
HCF:6
18/6=3
24/6=4
42/6=7
Therefore the simplified ratio of 18:24:42 is:
3:4:7

pls solve #4. very important
Answer:
Q2ΔABC~ΔDECRatios of corresponding sides are equal:
DE/AB = DC/ACDE/40 = 15/(15 +9)DE = 40*15/24DE = 25Q3ΔABD~ΔBCDRatios:
AD/BD = BD/DCAD*DC = BD²16*(20 - 16) = BD²64 = BD²8 = BDQ4If ΔABC ~ ΔXYZ, the ratios below should be equal:
AC/XZ = BC/YZ10/15 = 18/242/3 = 3/4Ratios are different so the triangles are not similar

Find the area of a sector with a central angle of 7.2 radians and a radius of 14 units
Please include steps
Answer:
[tex]\boxed {\boxed {\sf a= 705.6 \ units^2 }}[/tex]
Step-by-step explanation:
Since we are given the central angle in radians, we should use this formula for the sector area:
[tex]a=\frac{1}{2}r^2 \theta[/tex]
where r is the radius and θ is the angle in radians.
The radius is 14 units and the angle is 7.2 radians.
[tex]r= 14 \ units \\\theta= 7.2[/tex]
Substitute the values into the formula.
[tex]a= \frac{1}{2} (14 \ units)^2 (7.2)[/tex]
Solve the exponent.
(14 units)²= 14 units* 14 units =196 units²[tex]a=\frac{ 1}{2} (196 \ units^2)(7.2)[/tex]
[tex]a=\frac{ 1}{2}(1411.2 \ units^2)[/tex]
Multiply by 1/2 or divide by 2.
[tex]a= 705.6 \ units^2[/tex]
The area of the sector is 705.6 square units.
What is the greatest common factor of 48, 24, and 32?
Answer:
8
Step-by-step explanation:
Answer:
It is 2
Step-by-step explanation:
The greatest common factor is 2 because 2×16=32
also works for 24 because 2×24=48
then yes it works again for 2×12=24
division is also very helpful
A pie chart uses 360 degrees to represent 45 people. How many people are represented by an angle of 152 degrees
Answer: 19 people will be represented by an angle 152 degrees.
Step-by-step explanation:
Set up a proportional relationship to solve for this
[tex]\frac{360}{152} = \frac{45}{y}[/tex] Cross multiply
360y = 6840 Divide both sides by 360
y = 19

Answer:
D. r ≤ − 1
good luck, i hope this helps :)
Answer:
Step-by-step explanation:
Hello,
1. Follow PEMDAS, for instance, which is Parentheses, Exponents, Mult., Div., and so on.
This will help you simplify on each side of the inequality sign.
2. Signs of inequalities will switch (> becomes <, and < becomes >) when dividing by a negative number on both sides of an inequality.
Try to work with this first. If you need more help, let me know.

Hannah & Sal share 24 sweets.
5
1
Hannah gets - of them. Sal gets - of them.
NO
How many sweets do they each get?
24
Answer:
Hannah = 20, Sal = 4
Step-by-step explanation:
Total number of sweets = 24
Ratio in which the sweets was shared;
Hannah : Sal = 5 : 1
Hannah gets:
Hannah = 5 / ( 5+1) * 24 = 5/6 * 24 = 5 * 4 = 20
Sal gets:
Sal = 1 / ( 5+1) * 24 = 1/6 * 24 = 1 * 4 = 4

Step-by-step explanation:
how many yards
carpeting is needed to cover a 60 feet length room and 40 feet width
Answer:
[tex]266[/tex] [tex]\frac{2}{3}[/tex] [tex]yards[/tex]
Step-by-step explanation:
1. Approach
First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, [tex]3feet=1yard[/tex]. Next, find the area of the room by multiplying the length by the width.
2. Convert the unit of measurement
The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, [tex]3feet=1yard[/tex].
[tex]60feet=20yards\\\\40feet=13\frac{1}{3}yards[/tex]
3. Find the area of the room
Now multiply the length by the width to find the area of the room.
[tex]20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}[/tex]
