Tran drove his car at a constant speed of 55 mph.

Which is an equation for the distance Tran drove?

A. 55d=t

B. d=55t

C. t/d=55

D. 55/d=t

Plz help I think the answer is D am not sure.

Answers

The correct equation for the distance Tran drove at a constant speed of 55 mph is B. d = 55t.

In this equation:

"d" represents the distance in miles that Tran drove.

"t" represents the time in hours.

So, the distance "d" is equal to Tran's constant speed of 55 mph multiplied by the time "t" in hours, which is why the equation is written as d = 55t.

Option D is not the correct equation because it has the variables and constants in the wrong order.

The correct order is distance (d) on the left side of the equation, followed by the constant speed (55) and then the time (t) on the right side of the equation.

The correct option is d. 8 oz. can of juice is most convenient to meet this requirement.

First, let's convert 240 milliliters to ounces because the answer choices are in ounces.

1 milliliter is approximately equal to 0.0338 ounces.

So, 240 milliliters is approximately $ 240 \times 0.0338 $ ounces, which is about 8.112 ounces.

Now, let's examine the options:

a. 5 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.

b. 4 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.

c. 12 oz. can of juice: More than enough juice. It's more than the required 8.112 ounces.

d. 8 oz. can of juice: Exactly the amount needed. It matches the required 8.112 ounces, which is the closest to the calculated amount of 8.112 ounces.

Therefore, the 8 oz. can of juice is the most convenient option to meet the requirement of having 240 milliliters of juice every 2 hours.

what is rounding and estimate 253,495 - 48,617=

Answers

Rounding up or down to the nearest whole number, 253,000-49,000=204,000

Answer:

205000

Step-by-step explanation:

Given : 253,495 - 48,617

To Find : What is rounding and estimate

Solution:

To Estimate a difference by rounding.

1 ) Round each term that will be subtracted

2 )Subtract the rounded numbers

Round off of 253,495 = 253000

Round off of 48,617 = 48000

So, 253000 - 48000 = 205000

Hence The rounding and estimate 253,495 - 48,617= 205000

4 girls and 4 boys run. Then 2 more children run. The same number of girls and boys run. How many of each run

Answers

Hey there!

If we start out with the same amount of boys and girls at the beginning, then we must add the same number to both groups to maintain that same amount. In this case, since there's already 4 in both groups, you would need to split 2 in half and add the remainder to both groups.

2 ÷ 2 = 1
boys: 4 + 1 = 5
girls: 4 + 1 = 5

So, 5 girls and 5 boys are running.

When sales representatives for a pharmaceutical company drive out of town meetings that require an overnight stay, they receive $175 for lodging plus $0.70 per mile driven. How many miles did Joe drive if his company reimbursed him $329 for an overnight trip?
Set up an equation that can be used to solve the problem. Solve the equation and determine the desired value.

Answers

x=number of miles

$329=$175+$0.70x
329-175=.70x
154=.70x
154/.70=x
220miles =x

Joe was given $329 for an overnight trip because he drove a distance of 220 miles

Word Problem

Given Data

Amount rep receive = $175Added amount per mile driven = $0.70Reimbursed/Total = $329

The Mathematical relation for this scenario is

Total amount = Amount Receive+ 0.7*Distance driven

let the distance driven be x

Substituting our given data into the relation we have

329= 175+ 0.7*x

329-175 = 0.7x

154 = 0.7x

divide both sides by 0.7

x = 154/0.7

x = 220miles

A 25-foot streetlight casts a showdown 20feet long.If Melanie is standing at the end of the shadow casted by a 60. -foot tall building,how far is she from the building.

Answers

Melanie is 48 feet away from the building.
Heres my working

20% of 25=20 so 20% of 60=48.
Hope this helped ☺️

By setting up a proportion based on the similar triangles created by the streetlight and the building, we can find that Melanie is standing 48 feet away from the building.

To solve the problem of determining how far Melanie is standing from the building using the shadows, we can use similar triangles. We are given a 25-foot streetlight that casts a 20-foot shadow and a 60-foot tall building. The goal is to find the length of the shadow cast by the building, which will tell us how far Melanie is from the building.

By setting up a proportion based on the similar triangles, we have:

Height of the streetlight / Length of streetlight's shadow = Height of the building / Length of the building's shadow.25 feet / 20 feet = 60 feet / x feet.To find the value of x, we cross multiply:25x = 60 * 20.x = (60 * 20) / 25.x = 1200 / 25.x = 48 feet.

Therefore, Melanie is standing 48 feet away from the building.

Write the equation of a line whose slope is -2 and passes through (-1,6). Write the answer in slope-intercept form.

Answers

y = mx + b
slope(m) = -2
(-1,6)....x = -1 and y = 6
now we sub and find b, the y int
6 = -2(-1) + b
6 = 2 + b
6 - 2 = b
4 = b

so ur equation is : y = -2x + 4 <==

We are given an (X, Y) in (-1, 6). We are also given a slope of -2.

Start by plugging all those values into the slope intercept equation.

6 = -2*-1 + B

Solve for B.

B = 4

Now, all you have to do is put it back into the equation again, this time not using the (X,Y) we had initially, but just the slope (-2) and our new "B" value (5).

The resulting equation looks like this:

y= -2x + 4

And that's the answer.

What are 5/6 and 7/9 written with their least common denominator (LCD)?

Answers

Final answer:

The least common denominator of 5/6 and 7/9 is 18. This results in equivalent fractions of 15/18 for 5/6 and 14/18 for 7/9.

Explanation:

To find the least common denominator (LCD) of the fractions 5/6 and 7/9, we first find the least common multiple (LCM) of the two denominators, 6 and 9. The LCM of 6 and 9 is 18.

Next, we convert each fraction to an equivalent fraction with the LCD as the new denominator. We multiply the numerator and denominator of 5/6 by 3 to get 15/18. Similarly, we multiply numerator and denominator of 7/9 by 2 to obtain 14/18.

So the fractions 5/6 and 7/9, when written with their LCD, are 15/18 and 14/18, respectively.

divide 9x^2 square root by square root 18y^2

Answers

No answer for this problem

To start, first write out the expression, which would be √9x^2/√18y^2. Then, you simplify the radicals in the numerator and the denominator. Since 9 has a square root of 3 and x^2 has a square root of x, √9x^2 would simplify to 3x. Then, since 18 cannot be square rooted, you look for any ways to simplify it. Since √18 can be divided into √9 and √2, you find that it can be simplified into 3√2 since √9 simplifies to 3, so you leave the 3 outside while you keep the 2 inside. Now, you look at √y^2. This easily simplifies to y. Now your expression looks like this: 3x/3y√2. Then, since they both have a common factor of 3, you divide 3 from both sides. Now your expression looks like this: x/y√2. Since you have to rationalize the denominator (meaning no radicals in the denominator), you have to multiply your expression by √2/√2 in order to keep the expression equivalent and rationalized. Your final answer should be x√2/2y

solve the equation by completing the square 5x(x+6)=-50

Answers

First lets distribute the 5x
5x^2 + 30x = -50

Lets divide every term by 5
x^2 + 6x = -10

To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9

Add that to both sides of the equation
x^2 + 6x + 9 = -1

Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)

(x+3)^2 = -1

Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i

Final answer:

To solve the equation 5x(x+6) = -50 by completing the square, we first isolate the quadratic term and then add the square of half the coefficient of x to both sides of the equation. Taking the square root gives us the solution x = -3 + i and x = -3 - i.

Explanation:

To solve the equation by completing the square, we first need to isolate the quadratic term on one side of the equation. So, let's distribute the 5x to get 5x^2 + 30x = -50. Next, we move the constant term to the other side and divide the equation throughout by the leading coefficient to get x^2 + 6x + 10 = 0.

Now, we can complete the square by adding the square of half the coefficient of x (which is 3) to both sides of the equation. This gives us (x + 3)^2 + 10 - 9 = 0, which simplifies to (x + 3)^2 + 1 = 0.

Taking the square root of both sides, we get x + 3 = ±√(-1), which means x = -3 ± i. Hence, the solution to the equation is x = -3 + i and x = -3 - i.
