20 hundreds equals how many thousands?

Answers

Answer 1

Answer:

we know that

$1\ hundred=100$

$1\ thousand=1,000$

$1\ thousand=10\ hundred$

By proportion

Find how many thousands are $20\ hundreds$

$(1)/(10) (thousand)/(hundreds) =(x)/(20) (thousands)/(hundreds) \n\nx=20/10 \n\nx=2\ thousands$

therefore

the answer is

$2\ thousands$

Answer 2

Answer:

The number of 20 hundreds in 2 thousands is 2.

We are given that;

The number = 20 hundreds

Now,

20 hundreds equals 2 thousands.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

It is a method that we use for most of the calculations in math.

We can divide 20 by 10 to get the answer.

$(20)/(10) = 2$

Therefore, by the unitary method answer will be 2.

David drove 135 miles in 3 hours. What is the unit rate?

Answers

The answer is 45 miles per hour. The unit rate (r) is the number of miles (d) divided by the number of hours (t): r = d/t. We know that d = 135 miles and t = 3 hours. So, the unit rate is r = 135 miles/3 hours. r = 135/3 miles per hour. r = 45 miles per hour. The unit rate is 45 miles per hour.Hope this helps. Let me know if you need additional help!

Answer:

45 mph

Karen is seven years older than suzanne.Four years ago,karen was twice as old as suzanne was.How are they now?

Answers

$K-Karen\ age\nS-Suzanne\ age\nK-4-Karen\ age\ 4\ years\ ago\nS-4-Suzanne\ age\ 4\ years\ ago\n\n \left\{\begin{array}{ccc}K=S+7\nK-4=2(S-4)\end{array}\right\n\left\{\begin{array}{ccc}K=S+7&(1)\nK-4=2S-8&(2)\end{array}\right\n\nsubtitute\ (1)\ to\ (2):\n\n(S+7)-4=2S-8\nS+7-4=2S-8\nS+3=2S-8\ \ \ \ |subtract\ 3\ from\ both\ sides\nS=2S-11\ \ \ |subtract\ 2S\ from\ both\ sides\n-S=-11\n\boxed{S=11}$

karen age=k
suzanne age=s

karen (k) is (=) 7 years older (+7) than suzanne(s)
k=7+s

four year ago means
s-4 and k-4

four years ago (-4 to all) karen (k) was (=) twice (2 times) suzzane (s)
k-4=2(s-4)
distribute
k-4=2s-8
add 4 to both sides
k=2s-4
we know that k=7+s so subsitute 7+s for k
7+s=2s-4
add 4 to both sides
11+s=2s
subtract s from both sides
11=s

suzanne=11
subsitute 11 for s in k=s+7

k=7+11
k=18

karen=18
suzanne=11

Felipe put a bowl of candies on his desk. He grabbed the relationship between how many days had passed and how many candies remained. What does the X intercept represent in this context

Answers

Answer:

see the explanation

Step-by-step explanation:

Let

x -----> the number of days

y ----> the number of candies remained

we know that

The x-intercept is the value of x when the value of y is equal to zero

In this context, the x-intercept is the number of days that have passed when the amount of candy remaining is equal to zero.

Final answer:

The X intercept represents the number of days it takes for all the candies to be gone. When the line goes through the X-axis (X intercept), it means that there are no candies remaining in the bowl.

Explanation:

In the context of Felipe's bowl of candies, the X intercept on a graph represents the number of days it takes for all the candies to be gone. Essentially, the X intercept is when the Y value (in this case, the number of candies remaining) hits zero.

This is because the X-axis often represents time in such scenarios, and when the graphed line crosses, or 'intercepts' the X-axis, it means the count of what is being measured (candies here) has become zero. So, if the graph showed that the X intercept was 5, it would mean all of the candies were eaten within 5 days.
