Ratios

Caleb's Jumbo box has 30 cars, 12 of which are convertibles.

This gives a ratio of 12:30. The equivalent fraction of this ratio is:

[tex]\frac{12}{30}[/tex]

This fraction can be simplified by dividing both parts by 6:

[tex]\frac{2}{5}[/tex]

Thus Caleb's ratio of convertibles is 2:5.

Gabe's Mini box has 4 convertibles out of 10 cars. This gives a ratio of 4:10.

Simplifying by 2, the ratio is 2:5.

It's clear that both boxes have the same ratio of convertibles to total cars.

Answer: Yes

Answer:

x = -2i and x = 2i

x = 3 and x = - 3

Step-by-step explanation:

x^4 - 5x^2 - 36 = 0

let u = x^2 and substitute

we have:

u^2 - 5u - 36 = 0

(u - 9)(u + 4) = 0

u = 9 and u = - 4

substitute back for u

x^2 = 9

x = 3 and x = - 3

x^2 = -4 -- i am going to assume you've learned imaginary numbers; otherwise, you cannot take the square root of a negative number.

x = -2i and x = 2i

Step-by-step explanation:

Answer:

Just subtract, 400 - 50 = 350, 350 - 50 = 300....etc until you reach (8,0) point on the graph. Graph a straight line down from starting point (0,400) on graph to (8,0). This is your answer subtract 50 from 400 until you reach 0. Starting point (0,400) and ending point (8,0), it's a straight line down ward..

Answer:

2.47g

Step-by-step explanation:

Given that Ao=14

A(t)= Aoe^kt

k =2yrs

Considering the function where Ao is the initial substance, k is the rate of decay and t is the time.

At the 2nd year A(t) is 7

That is,

7 = 14e^2k

Solve for k

7/14 = e^2k

In(7/14) = 2k

k = In(7/14)÷2

k = In(0.5)/2

k = -0.34657

Hence, A(t)= 14e^-0.34657

So, when t is 5

A(5) = 14e^-0.34657×5

= 2.4749

Approx = 2.47g

Step-by-step explanation:

Answer:  D) 32.8

=======================================================

Work Shown:

We'll apply the tangent ratio

tan(angle) = opposite/adjacent

tan(64) = x/16

16*tan(64) = x

x = 16*tan(64)

x = 32.8048614652688

x = 32.8

Make sure your calculator is in degree mode. One way to check is to compute tan(45) and you should get 1 as a result.

Jan will have 12 marbles

Kim will have 14 marbles

Jan and Kim own 40 and 48 marbles respectively.

Important information:

We need to find the initial number of marbles each own.

Let the initial number of marbles be [tex]5x[/tex] and [tex]6x[/tex].

Jan gains 2 more marbles and the ratio is 7:8. So,

[tex]\dfrac{5x+2}{6x}=\dfrac{7}{8}[/tex]

[tex]8(5x+2)=7(6x)[/tex]

[tex]40x+16=42x[/tex]

Isolate the variable.

[tex]16=42x-40x[/tex]

[tex]16=2x[/tex]

[tex]\dfrac{16}{2}=x[/tex]

[tex]8=x[/tex]

Now, find the initial number of marbles.

[tex]5(8)=40[/tex]

[tex]6(8)=48[/tex]

Therefore, Jan and Kim own 40 and 48 marbles respectively.

The linear function is given by y = -2000x + 30000

A linear function is a function in the form:

y = mx + b

where y,x are variables, m is the rate of change and b is the y intercept.

Let y represent the value of the car after x years.

From the graph, the line passes through point (0, 30000) and (3, 24000), hence:

[tex]y-30000=\frac{24000-30000}{3-0} (x-0)\\\\y=-2000x+30000[/tex]

Answer:

Step-by-step explanation:

If y y varies directly with x, this is expressed as;

y ∝ x

y = kx

k is the constant of proportionality;

Given

x = 4 and y = 8

Substitute;

8 = 4k

4k = 8

k = 8/4

k = 2

Hence the constant of proportionality k is 2
