Answer:

Check the explanation

Step-by-step explanation:

Part (A)

Kindly check the First attached image below to get the explanation the part A question.

Part (B)

As calculated in part (A), if we have 40 numbers of buns and hot dogs, there are no leftovers.

So every multiple of 40, will ensure no leftovers.

40, 80, 120, 160, 200, 240, 280, 320...

since 300 people are attending, 320 such buns and hot dogs are required.

packages of Bun = 320/8 = 40

packages of hot dogs = 320/10 = 32

(bun package,hot dog package) = (40,32)

Part (D)

In part (C), it came out the ratio

(buns packages : patties packages : jar of pickles) = (3:2:4)

Kindly check the Second attached image below

so to feed 420 people,

24*k > 420 such that minimum value of k

k = 18

so total 432 hamburgers will be formed.

Bun packages = 432/8 = 54

Patties packages = 432/12 = 36

Pickle jar = 432/6 = 72

so answer is (bun package, patties package, pickle jar) = (54,36,72)

Help please !!!!!!!!

Answer:

y = -4

x = 3

Step-by-step explanation:

Let's first explain when x = 0

Find where x = 0 on the graph. We are finding what the y-value would be. Trace down the y-axis along the vertical line x = 0. Where does the line intersect the y-axis when x = 0? The answer would be -4

The y-intercept is -4, and the x-value for this is 0, of course. So the correct answer for when x = 0 would be y = -4.

Next, we are told to find x when y = -2. Find where y = -2. Now, staying at y = -2, go horizontally along the x-axis at y = -2 until you reach the line. Boom! You should have connected up with the line at around x = 3. Therefore, when y = -2, x = 3

Answer:

D. $-\frac{3}{4}$

Step-by-step explanation:

The given equation is

$4y=8x-3$

When we divide through by 4 we get;

$y=2x-\frac{3}{4}$

Comparing to

y=mx+c,

The y-intercept is $-\frac{3}{4}$

The corrrect choice is D.

A scientist has 100 milligrams of a radioactive element. The amount of radioactive element remaining after t days can be determi

grandymaker [24]

The mass of the first shipment at time t is
$m_{1}=100( \frac{1}{2} )^{ \frac{t}{10}}$

The mass of the second shipment at time t is
$m_{2}=100( \frac{1}{2} )^{ \frac{t-3}{10} }$

At time t, the ratio of m₁ to m₂ is
$\frac{m_{1}}{m_{2}} = \frac{100}{100}. \frac{(1/2)^{t/10}}{(1/2)^{(t-3)/10}} \\ = \frac{(1/2)^{t/10}}{(1/2)^{t/10}}. \frac{1}{(1/2)^{-3/10}} \\ = (1/2)^{3/10} \\ = 0.8123$

Therefore as a percentage,
$\frac{m_{1}}{m_{2}} =100*0.8123 = 81.23 \%$

Answer: B. 81.2%
