Solve d = rt if r = 46 and t = 5

Answers

Answer 1

Hey!!

r=46

t=5

now,

D=RT

= 46*5

=230

the value of d is 230

hope it helps..

Answer 2

Answer:

230 is the answer

Step-by-step explanation:

Since r and t are given in the question as

r=46 and t=5

Substitute the value of r and t which is given in the polynomial

So it'll be,

d=rt

d = 46 x 5

= 230

Therefore d is 230 units

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?

Answers

Answer:

Let's start by using variables to represent the ages of the three people:

Let L be Liz's age.

Let D be Debbie's age.

Let F be Freya's age.

From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:

L = (2/3)D

We also know that Debbie's age is half of Freya's age, so we can write:

D = (1/2)F

To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:

F = 2D

Now we can substitute this expression for F into the equation for Liz's age:

L = (2/3)D = (2/3)(1/2)F = (1/3)F

So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

The ratio of Liz’s age to Freya’s is 1:3

PLS HELP ! Solve the addition equation by finding a common multiple. one half + two thirds + four sixths equals ___

Answers

Answer: 1/2 + 2/3 + 4 /6 = 11/6

Step-by-step explanation:

1/2 + 2/3 + 4 /6

We need to find a common multiple, for the denominator. Let us choose 6, so we do not have to deal with large numbers.

Note that we do not change 4/6, since it already has a denominator of 6.

==> 3/6 + 4/6 + 4/6

Add;

==> 11/6

3/6 + 4/6 + 4/6 equal to 11/6

To find the interest earned by Account A, we can use the formula:

Interest = Principal x Rate x Time

Plugging in the given values, we get:

Interest = $1,500 x 0.04 x 3 = $180

So Account A earns $180 in interest over three years.

Similarly, we can find the interest earned by Account B using the same formula:

Interest = Principal x Rate x Time

Plugging in the given values, we get:

Interest = $1,500 x 0.06 x (21/12) = $157.50

So Account B earns $157.50 in interest over 21 months.

To compare the interest earned by the two accounts, we can see that Account A earns more interest than Account B, even though the interest rate is lower. This is because the time period is longer for Account A, giving the interest more time to accrue.

Example 1: Two principal amounts and two simple interest rates that would earn equal amounts of interest in one year are:

Principal 1 = $1,000
Rate 1 = 5%
Interest 1 = $50

Principal 2 = $2,000
Rate 2 = 2.5%
Interest 2 = $50

Example 2: Two principal amounts and two periods of time for which the simple interest earned at 2.59% would be equal are:

Principal 1 = $500
Time 1 = 4 years
Interest 1 = $51.80

Principal 2 = $1,000
Time 2 = 2 years
Interest 2 = $51.80

Responses
A 3939
B 1616
C 3737
D 1313
E 17

Answers

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

16
2+3+5+9+17+22+31+39=128
128/8=16

A pole that is 3.2m tall casts a shadow that is 1.14m long. At the same time, a nearby tower casts a shadow that is 39.75m long. How tall is the tower? Round your answer to the nearest meter.

Answers

Answer:

112 meters

--------------------------------

The heights and shadows are proportional since they form similar triangles.

Set equal proportions and solve for the missing length:

H/h = S/s, where H and h represent heights, S and s - shadows.H/3.2 = 39.75/1.14H = 3.2*39.75/1.14H = 112 (rounded)

Answer:

112 meters

Step-by-step explanation:

3.2/1.14 = x/39.75

3.2/1.14 = 2.81

2.81 * 39.75 = 111.57 = 112

Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2

Answers

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages

Adam is purchasing a new television that costs $2,187.96 after tax. He borrowed the money from his parents and must pay back the full amount plus simple interest at the rate of 3.5%. What is the total amount he will pay if he takes 2 years to pay his parents back? (Include Decimal with the cents; No Commas)

Answers

He will pay 2264.54 with 3.5% interest

It is determined that he will pay an interest of $153.16 using simple interest and taking the exercise's specified criteria into account.
Basic Interest
When there is only one compounding every time period, simple interest is applied.
The formula for calculating interest after t years is 1 = Prt.
Where P is the initial sum and r is the interest rate in decimal form.
The following are the parameters for this problem:
P = 2187.96, r = 0.035, t = 2.
The interest will therefore be paid at the rate of 1=Prt = 2187.96 x 0.035 2 = $153.16.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Step-by-step explanation:

First we find the area of the rectangle, based on the diagram, this rectangle measures 10cm by 1cm, or 10cm².

After that we find the area of the half circles, In this case I'm going to assume the half circles have the same diameter. The diameter in 2cm, and the radius is half of the diameter. Sine you need the radius to find the area of the circle we will divide the diameter by 2. So 2 ÷ 2 is 1. Then with this radius we will use the formula for the area of a circle, πr².

3.14(1)²

3.14cm²

In most half circles you would divide by two cince this formula calculates the area of a full circle, but two identical half circles is the same as one full circle.

Add the area of the half circles to the area of the rectangle and you get your answer!

Answer:

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer: A

Step-by-step explanation:

$\frac{J}{H} = G + \frac{I}{H}$ >Since you are solving for H bring I/H to the other side

by subtracting I/H from both sides

$\frac{J}{H}- \frac{I}{H} = G$ >There is a common denominator so you can

combine the fractions

$\frac{J-I}{H} = G$ >Multiply both sides by H or cross multiply whichever

way your mind things about how to get H on top

$J-I = G(H)$ >Divide both sides by G

$\frac{J-I}{G} = H$ >Answer is A
