Step-by-step explanation:
Lola's pet turtle walked 10 feet, and then half that length again. This means that Lola's pet turtle walked:
= 10 + (1/2 × 10) = 10 + 5 = 15 feet
Lola's baby brother walked 3 feet, and then half that length again. Total length walked will be:
= 3 + (1/2 × 3) = 3 + 1.5 = 4.5 feet
Lola's hamster walked 6.5 feet, and then half that length again. Total length walked will be:
= 6.5 + (1/2 × 6.5) = 6.5 + 3.25 = 9.75
Lola's mom walked x feet, and then half that length again. Total length walked will be:
= x + (1/2 × x) = x + 0.5x = 1.5x
Total feet walked by the whole member of the family will be:
= 15 + 4.5 + 9.75 + 1.5x
= 29.25 + 1.5x
Answer:
turtle: 10 + 5 = 15
brother: 3 + 1 1/2 = 4 1/2
hamster: 6 1/2 + 3 1/4 = 9 3/4
Mom: x + 1/2x = 1 [tex]\frac{1}{2}[/tex]x

Answer:
Area of circle - Area of square
radius of circle is 8m
side of squre os 12m
Step-by-step explanation:
Area of circle is pie r^2
22/7 × 8 × 8
22/ 7 × 64
= 201.14m^2
Area of square is side ^2
12 ×12
= 144m^2
hence 201.14 - 144
= 57.14m^2 is the area of shaded figure

Remember...
5 or more? raise the score, 4 and below let it rest
The number in the tenths place, in this case, is 5 and the number next to it is 4, and since 4 is less than 5, you do not round 5 up to 6, you simply leave it alone!

Express sin A, cos A, and tan A as ratios.
12
613
Answer:
see explanation
Step-by-step explanation:
sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{6\sqrt{3} }{12}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]
cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]
tanA = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{6\sqrt{3} }{6}[/tex] = [tex]\sqrt{3}[/tex]

Si un automóvil tiene 1.500 kg de masa y una velocidad de 5 m/s, ¿cuál es la energía cinética de un automóvil?
Answer:
E = 18750 J
Step-by-step explanation:
The question is "If a car has a mass of 1,500 kg and a speed of 5 m / s, what is the kinetic energy of a car?"
Mass, m = 1500 kg
Speed, v = 5 m/s
We need to find the kinetic energy of the car. The formula for kinetic energy is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 1500\times (5)^2\\\\K=18750\ J[/tex]
So, 18750 J is the kinetic energy of the car.
Adam and Katy both receive a bonus.
Adam receives 30% of £80
Katy receives £28
Work out the difference between the bonus Adam gets and the bonus Katy gets.
Step-by-step explanation:
Adam's bonus
30/100= 0.3
0.3 *80=24
therefore Adam's bonus is £24
since Katy bonus is £28
The difference between the bonus Adam gets and the bonus Katy gets
£28 -£24 =£4
Jackie runs and rides her bike. She runs 6 miles an hour. She bikes 18 miles an hour. Last week she ran and bikes a total of 216 miles. It took her 16 hours. How many hours did Jackie run and bike last week. Show your work
Answer: she bikes for 10 hours and runs for 6
Step-by-step explanation: suppose that x equals the amount of hours she runs and y equals the amount of hours she bikes.
6x+ 18y=216
x+y=16
(This is your system of equations)
(Starting with the second equation, x+y=16)
y=-x +16 (move x to the other side by transposition)
Now that you have something that equals Y you plug it in to the other equation:
6x+18(-x+16)=216
(Start solving)
6x-18x+288=216 (used distributive property)
-12x+288=216 (Combine like terms)
-12x=-72 (use transposition again)
x=6 (divide to get x by itself)
Now you plug in the value of x into your equation for the value of “y”, y=-x+16,
Y=-6+16 (plugged in the value of x)
Y=10 (solved the equation -6+16)
Question 20:- Fahein is interested in purchasing an AC too. He will give three times more points to energy efficiency and two points more to noise levels than sevices and installation. Whereas, design features don't matter to him. In this case he devises a way to compare the 5 models. Which one is the correct formula given his preferences?
Answer:
[tex]Total = 3E + 2N + S[/tex]
Step-by-step explanation:
Given
Represent
Efficiency with E; Noise Level with N
and Service and Installations with S
Required
Determine the correct formula
From the question
3 points goes to E: i.e. 3E
2 points goes to N: i.e. 2N
The above is the number of points more than service and installations.
So 1 point will be given to S i.e. S
The total or formula is:
[tex]Total = 3E + 2N + S[/tex]

Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile. What is the total distance Petrov ran in feet?
Answer:
9240 feet
Step-by-step explanation:
Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile.
Step 1
The total distance Petrov ran in miles is calculated as:
1 lap = 1/4 mile
7 laps = x mile
Cross Multiply
x = 7 × 1/4 mile
x = 1.75 miles
Step 2
What is the total distance Petrov ran in feet?
1 mile = 5280 feet
1.75 miles = x
Cross Multiply
x = 1.75 × 5280 feet
x = 9240 feet
Therefore, the total distance Petrov ran in feet is 9240 feet

Which function is equivalent to g(x) = 9 x2 - 24 x + 16?
Answer:
Step-by-step explanation:
discriminant = (-24)² - 4(9)(16) = 0, so there are two identical roots.
That eliminates choices 2 and 4.
Quadratic formula
x = [24 ± √(24² – 4·9·16)] / [2·9]
= 24 / 18
= 4/3
9x² - 24x + 16 = 9(x-4/3)² = (3x-4)²
