Step-by-step explanation:

You have to divide 2/5 by 6 to find the answer. 6/1 divided by 2/5 equals 6/1 x 5/2, which equals 30/2. 30/2 equals 15. Hope this helps!

Answer: 4

Step-by-step explanation:

Think of this ratio like a scale that needs to be kept in balance. Whatever changes you make to one side, you need to make to the other.

33 ➗ 11 = 3

44 ➗ 11 = ? = 4

Step-by-step explanation:

Jeff spends $2.52 per gallon and buys 14 gallons, so his total expenditure is:

Total spent by Jeff = $2.52/gallon * 14 gallons = $35.28

Anna spends $2.16 per gallon and buys 15 gallons, so her total expenditure is:

Total spent by Anna = $2.16/gallon * 15 gallons = $32.40

To find the difference in their expenditures, we subtract Anna's total from Jeff's total:

Difference = Total spent by Jeff - Total spent by Anna

Difference = $35.28 - $32.40 = $2.88

Therefore, Jeff spends $2.88 more than Anna on gas.

healthy heart with a normal cardiac output pumps about 5 to 6 liters of blood every minute

Answer:

\(2<\sqrt{8}<3<\dfrac{\sqrt{90}}{3}<4<\sqrt{20}<5<4\sqrt{2}\)

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

Step-by-step explanation:

im assuming you solve for r.

-8r<-12

divided by -8 on both sides so you change signs

r>12/8

r> $ 3/2

Answer:

$r > 1.5$ or \(\frac{3}{2}\)$

Hope this helps!

Step-by-step explanation:

Hiding the dollar signs real quick:

-8r < -12

Divide both sides by -8: ( remember that when multiplying or dividing both sides by a negative number reverses the inequality )

-8 ÷ -8 × r < -12 ÷ -8  =  r > 1.5 or \(\frac{3}{2}\)

Answer:

56,250 cubic centimeters

Step-by-step explanation:

A cuboidal wooden box is nothing but a rectangular prism

The volume of a rectangular prism = L x B x H where L = length,, b = breadth and H = height

Should be easy enough, but wait....the dimensions are not all in the same units

L is in meters whereas B and H are in cm

So convert L to cm.
1 meter = 100 cm

1.5 m = 1.5 x 100 = 150 cm

Using the values given

Volume =  150 x 25 x 15 = 56,250 cubic centimeters

Answer:2764800

Step-by-step explanation:First step is to convert feet into inches:

1 foot = 12 inches

20feet = 20*12=240 inches

8feet = 8*12=96 inches

Now we can calculate total area:

A = height * width

A= 240 * 96

A=23040 inches²

We know the amount per one inch² and we need to find out total number of blades:

1 inch²                          120 blades

23040 inches²               x blades

Now we cross-multiply numbers:

1*x = 23040 * 120

x= 2764800

There are total of 2764800 blades in the entire law

Step-by-step explanation:

3÷3=9

3÷2=6

3÷5=15

Answer:

Step-by-step explanation:

Answer:

it is 6

Step-by-step explanation:

because if you subtract 12.6 - 6.6 = 6 so 6 + 6.6 is 12.6

Answer:

A = 6

Step-by-step explanation:

To solve the equation A + 6.6 = 12.6, you need to isolate the variable "A," which represents an unknown value.

Subtract 6.6 from both sides of the equation:

=> A + 6.6 - 6.6 = 12.6 - 6.6

Simplifying this equation gives:

=> A = 6

Therefore, the solution to the equation A + 6.6 = 12.6 is A = 6.

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer:

Step-by-step explanation:

The discriminant of this equation, i.e, D=\(b^{2}-4ac\) is less than 0:

D= 0-(4*2*18)   --> which is clearly negative

When D is less than 0, the equation has no real number solutions.

Therefore, \(2x^{2}+18=0\) has no real roots

The opinion of Aiden about equivalent expressions always having the same number of terms is; Not correct

Aiden is not correct with his assertion as we will see for four major operations.

We can see that in both cases the expressions have equivalent answers but the number of terms are not the same.

Same scenario also applies for division and subtraction. Thus, we can say that Aiden is not correct.
