A rectangular room has a width 1.6 times its length, and its perimeter is 26 meters. Find the dimension of the room, round to the hundredth place.
Answer:
The dimension of the room is Length of 5m and Width of 8m
Step-by-step explanation:
Formula for perimeter of a rectangle is;
P = 2(L + W)
Where;
L is length
W is width
We are given;
Width; W = 1.6L
Perimeter; P = 26 m
Thus;
2(1.6L + L) = 26
2(2.6L) = 26
5.2L = 26
L = 26/5.2
L = 5 m
W = 1.6 * 5
W = 8 m

What number belongs in the green box?
By taking the product of the two fractions we will see that the number that goes in the green box is a 6.
How to add two fractions?
We only can add two fractions if we have the same denominator in both of them, here we want to transform -2/3 in an equivalent fraction, such that the denominator is 9, so we multiply both the numerator and denominator by 3.
So we need to solve:
[tex]\frac{-2}{3}*\frac{3}{3} = \frac{-2*3}{3*3} = \frac{-6}{9}[/tex]
From that, we can conclude that the number that goes in the green box is 6.

When the light turns green, John accelerates straight down the road at 1.8 m/s for 8 seconds. What is his final velocity at the end of those 8 seconds
Acceleration is the rate of change of velocity over time
His final velocity is 14.4 meters per second
How to determine the final velocityFrom the question, we have:
Initial velocity: u = 0 m/sTime = 8 secondsAcceleration = 1.8 m/s^2Using the first equation of motion, we have:
[tex]v = u + at[/tex]
So, the equation becomes
[tex]v = 0 + 1.8 * 8[/tex]
[tex]v =14.4[/tex]

Alex has been studying for the certified management exam. Results from the last exam indicate that the mean was 62 with a standard deviation of 6. He needs to be in the top 20% (80th percentile) to pass. Use z value with two decimal places, 1.28, in your calculations. What score will place Alex in the top 20% of the distribution
Alex needs a score of about 70 to be in the top 20% of the distribution
Z scoreThe z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ)/σ
Where x is raw score, μ is mean and σ is standard deviation.
Given that μ = 62, σ = 6, z = 1.28, hence:
1.28 = (x - 62) / 6
x = 69.68

A student bought a sandwich for 80 cents, milk for 20 cents, and a pie for 30 cents. How much did the meal cost?
[tex]\huge \text{Hello there! :)}[/tex]
Answer:
130 cents, or $1.30.
Step-by-step explanation:
To find the total cost of the meal, add the costs of each product.
Since the cost of the sandwich was 80 cents, the cost of the milk was 20 cents and the cost of the pie was 30 cents, then the total cost of the meal (in cents) is:
[tex]80+20+30[/tex]
Add the numbers from left to right. Since 80+20 is equal to 100, then:
[tex]80+20+30=100+30[/tex]
Finally, notice that 100+30 is equal to 130:
[tex]100+30=130[/tex]
So, the total cost of the meal was 130 cents. Each 100 cents is equal to 1 dollar. Then, 130 cents is the same as $1.30.
Therefore, the cost of the meal was 130 cents, or $1.30.

Answer: w = 9
Isolate the variable by dividing each side by factors that don't contain the variable. First, we rearrange the terms.
18 + 4w = 6w
4w + 18 = 6w
Now we subtract 18 from both sides.
When we simplify, we get that w = 9.
Step-by-step explanation:
Hope this helps =)
Answer:
w = 9
Step-by-step explanation:
Rearrange terms
4w + 18 = 6w
Subtract 18 from both sides of the equation
4w+18-18 = 6w -18
Simplify
4w=6w-18
Subtract 6w from both sides of the equation
4w-6w=6w-18-6w
Simplify
-2w=-18
Divide both sides of the equation by the same term
-2w = -18/-2
Simplify
w = 9
