Answer:
7.25
Step-by-step explanation:
In the question, the term at least means less than or equal to is represented by ≥
Let the cost of each gift = c
He is buying gifts for 8 friends = 8 gifts
Hence, our Inequality equation is written as:
(c + $1.50)× 8 ≥ $70
8c + 12 ≥ 70
8c ≥70 - 12
c ≥ 58/8
c≥ 7.25
Therefore, the amount Claudio needs to spend on each gift in order to receive free shipping is 7.25
Which expression is equivalent to 25 times 1/5?
A: 1/25 times 5
B: 1/25 times 1/5
C: 1/25 divided by 1/5
D: 5 divided by 25
E: 25 divided by 5
Answer:
E
Step-by-step explanation:
25 times 1/5 is saying divide 25 by 5 because 25 times 1/5 in 25/5 which is equal to 5 where 25 divided by 5 is 5.

Write an expression for the sequence of operations described below add 3 to b, then triple the result
Answer:
9 + 3b
Step-by-step explanation:
This is a rather very simple question to solve. And the first step is to look at the variables given.
From the question, we're told to add 3 to b
This means that
3 + b
Then, we are told to triple the result. This means that we multiply it by 3.
3 (3 + b)
And when we open the brackets, we have something like this
9 + 3b
3x (20 - 2), when x = 7
Answer: 378
Step-by-step explanation:
You would get this answer because if x = 7 then you multiply and get 21 because 3 x 7 = 21 then you do what’s in the parentheses and get 18 then multiply 21 x 18 then you get 378

Answer:
1/10 = 0.1 = (0.1×100) %= 10%
1/5 = 0.2 = (0.2×100)% = 20%
3/4 = 0.75 = (0.75×100)% = 75%
3/10 = 0.3 = (0.3×100)% = 30%
1/4 = 0.25 = (0.25×100)% = 25%
Hope it helps
Answer:
1/2 = 0.5 50%
1/10 = 0.1 10%
1/5 = 0.2 20%
3/4 = 0.75 75%
3/10 = 0.3 30%
1/4 = 0.25 25%
Given () = −^3 + 2^2 +(3/2) be the position of a particle moving along the x-axis at time t. At what time will the instantaneous velocity equal the average velocity over the time interval [0, 4]
Answer:
5.266 secs
Step-by-step explanation:
Lets assume ; p(t) = t^-3 + 2^2 + ( 3/2 ) is the particle position along x-axis
time interval [ 0, 4 ]
Average velocity = Displacement / time
= p( b ) - p( a ) / b - a -------- ( 1 )
where a = 0 , b = 4 ( time intervals )
Back to equation 1
Average velocity = [ ( 4^-3 + 4 + (3/2) ) - ( 0 + 4 + (3/2) ) ] / 4
= 3.9 * 10^-3 ----- ( 2 )
Instantaneous velocity = d/dx p(t)
= - 3/t^4 ------ ( 3 )
To determine the time that the instanteous velocity = average velocity
equate equations (2) and (3)
3.9*10^-3 = - 3 / t^4
t^4 = - 3 / ( 3.9 * 10^-3 ) = - 769.231
hence t = [tex]\sqrt[4]{- 769.231 }[/tex] = 5.266 secs
we ignore the negative sign because time can not be in the negative
I need help with geometry
Answer:
146
Step-by-step explanation:
angle AB is an inscribed angle and arc AB is it's intercepted arc
An inscribed angle is equal to half the measure of its intercepted arc
Which means that an intercepted arc is equal to two times the measure of its corresponding inscribed angle
Thus, arc ab = 2(73)
2 * 73 = 146
hence, arc AB = 146
Answer:
mAB = 146°
Step-by-step explanation:
We can notice that the angle given is an inscribed angle and an inscribed angle is 1/2 the arc it intercepts. We can set up an equation to model the situation:
73° = 1/2(mAB)
mAB = 146°

Four streets feed into a roundabout circle as shown below. If the diameter of the
roundabout is 130 feet, find the approximate distance a car will travel between Cole Street
and Maple Street along the roundabout.
Answer:
The answer is C. 119.1
Step-by-step explanation:
The arch measure between Cole St. and Maple St. is 105 degrees which is equal to 7/24 of the circumference. since the diameter is given simply multiply the circumference by 7/24 which equals 285,887/2400. Divide these and you get your answer.

The sum of two numbers is 65. The larger number is five more than three times the smaller number. What are the numbers? (Systems of Equations)
Answer:
x=44 and y=21
Step-by-step explanation:
The large one is x
The small one is y
According to given conditions,
x+y=65[Sum of two number is 65]—Equation(1)
x-23=y [Smaller number is less than 23 than larger]——Equation (2)
From equation (2) we can write,
x-y=23——-Equation(3)
Now adding equation (1) and (3) we get,
x+y+x-y=65+23
=>2x=88
=>2x/2=88/2 [Both sides are divided by 2]
=>x=44
Now putting the values in equation (2) we get,
44–23=y
=>y=21
Large, x=44 and Small, y=21

Aquarium has a height of 25 inches and a radius of 21 inches what is the volume of the aquarium in cubic inches
Answer:[tex]34,650\ in^3[/tex]
Step-by-step explanation:
Given
The height of the aquarium is [tex]h=25\ inches[/tex]
The radius of the aquarium is [tex]r=21\ inches[/tex]
Assuming aquarium to be in the shape of a cylinder
So, its volume is [tex]V=\pi r^2h[/tex]
Insert the values
[tex]\Rightarrow V=\pi \times 21^2\times 25\\\Rightarrow V=34,650\ in^3[/tex]
Thus the volume of the aquarium is [tex]34,650\ in^3[/tex].
A train is moving at an average speed of 180 m/s. how long will it take to reach the station. Both stations are 80 km apart?
1 km = 1000 meters.
Find total meters: 80 km x 1000 meters per km = 80,000 meters.
Divide total meters by the given speed:
80,000 meters / 180 m/s = 444.44 seconds.
1 minute = 60 seconds
444.44. Seconds / 60 seconds per minute = 7.41 minutes = 7 minutes 24.42 seconds
Total time = 7 minutes 24.42 seconds
Round as needed.

The lifespan of a hamster is 4 years less than that of a rabbit. The lifespan of a raccoon is 2 times that of the hamster. If the total lifespan of the animals is 24 years, calculate the longevity for the rabbit.
Answer:
9 years
Step-by-step explanation:
Let
Lifespan of rabbits = x
Lifespan of hamster = x - 4
Lifespan of raccoon = 2(x - 4)
Total lifespan of animals = 24
Total = rabbits + hamster + raccoon
24 = x + (x - 4) + 2(x - 4)
24 = x + x - 4 + 2x - 8
24 = 4x - 12
24 + 12 = 4x
36 = 4x
x = 36/4
x = 9 years
longevity for the rabbit = 9 years
Lifespan of rabbits = x = 9
Lifespan of hamster = x - 4
= 9 - 4
= 5
Lifespan of raccoon = 2(x - 4)
= 2(9 - 4)
= 2(5)
= 10
Total lifespan of animals = 24

You receive $45 profit from a car wash after $300 in sales.
What percent was your profit?
Answer:
15%
Step-by-step explanation:
Find the percent of profit by dividing 45 by 300:
45/300
= 0.15
So, the percent profit was 15%
You receive 45\$ profit from a car wash after 300\$ in sales.
