A rectangular tank with length 50 cm and width 30 cm contains 36 litres of water. Find the depth of the water.

Answers

Answer:

24cm

Step-by-step explanation:

Given data

Length=50cm

Width= 30cm

Volume = 36liters

=36000cm^3

We know that the expression for volume is

V= L*W*H

substitute

36000=50*30*H

36000= 1500*H

H= 36000/1500

H= 24cm

Hence the height is 24cm

Linda is 3 1/years younger than Rose. Joahn is 8 1/3years older than Linda. To the nearest year, what is the difference in Rose's age and Joahn's age?

Answers

Answer: 5 years

Step-by-step explanation:

Given

Linda is [tex]3\ \frac{1}{3}\ yr[/tex] younger than Rose

Johan is [tex]8\ \frac{1}{3}\ yr[/tex] older than Linda

Suppose the age of Rose is [tex]x[/tex]

So, Linda's age

[tex]x-\dfrac{3\times3+1}{3}=x-\dfrac{10}{3}[/tex]

Johan's age

[tex]x-\dfrac{10}{3}+\dfrac{8\times3+1}{3}=x+\dfrac{-10+25}{3}\\\\x+\dfrac{15}{3}=x+5[/tex]

Difference between the Rose's and Johan's age is

[tex]\Rightarrow x+5-x=5\ yr[/tex]

Nic sells advertising packages for a radio station. The company pays him $150 per week and they also pay him $75 for every package he sells. His friend Asia works for the same radio station but she receives a salary only, which is $1,275 per week. How many packages does Nic need to sell in a week to earn as much as Asia?

Answers are:
A) 14
B) 15
C)16
D)20

Answers

I believe the answer would be 15, because Nic makes a base of $150 per week, so you would do the base $150+75=225 and keep going until you get 1275. The # of packages Nic would need to sell to reach Asia’s weekly pay is 15.

Answer:

60.22in^2.

Step-by-step explanation:

First, find the area of the rectangle. 14.1x7=98.7.

Then, we need to find the area of the circle and subtract it from the area of the rectangle.

The area of the circle is pi*r^2. so, pi*3.5^2 is about 38.48. (The radius is half of the diameter, so the radius would be 3.5).

Since there are two halves of the circle, we can just subtract 38.48 from 98.7 so get the area of the shaded region. So, the area of the yellow area is 60.22in^2.

Find rectangle area: 14.1 x 7 = 98.7

Find areas of semicircles: a = 3.14(3.5)^2 = 76.96

Subtract area of semicircles: 98.7 - 76.96 = 21.74

1-point free throw 2-point field goal he made 35 shots he scored 62 points how many of each shot does he make in 1 minute write the two equations for the problem

Answers

Answer:

x + y = 35  equation 1

x + 2y = 62  equation 2

He made 8 1 point free throw

He made 27 2 point field goal

Step-by-step explanation:

let x = 1 point free throw

y = 2 point field goal

two equations can be derived from the question

x + y = 35  equation 1

x + 2y = 62  equation 2

Subtract equation 1 from 2

y = 27

Substitute for x in equation 1

x = 35 - 27 = 8

He made 8 1 point free throw

He made 27 2 point field goal

ii. If the line intersects the curve in two distinct points, find the set of values of b, given m=-5

Answers

Answer:

Below in bold.

Step-by-step explanation:

i, This is a rectangular hyperbola with symmetry about the line y = -x

   If it touches the graph at one point only then

y = 25/x

y = mx + b so

25/x = mx + b

mx^2 + bx + 25 = 0

Using the quadratic formula:

x = (-b + sqrt(b^2 - 25*4*m)) / 2m

Now there's only one value of x so

b^2 - 25*4*m = 0

b^2 = 100m

m = b^2/100.

m = +/-b/10.

ii  In this case b^2 > 100m

If m = |-5|

b^2 > 500

b > +/-√500

So b > √500 or b < -√500.

F(x)=400-4/5x find the function and intercepts

Answers

Answer:

The x-intercept is (500, 0);  the y-intercept is (0, 400).

Step-by-step explanation:

F(x)=400-4/5x is already a function:  a function of x.

To find the y-intercept, set x = 0 and calculate F(0):

    F(0) = 400 - 0 = 400; the y-intercept is (0, 400).

To find the x-intercept, set F(x) = y = 0 and solve for x:

     0 = F(x) = 400 - (4/5)x, or (4/5)x = 400.  To isolate x, multiply both

     sides by (5/4):  x = (5/4)(400) = 500.  The x-intercept is (500, 0).
