Step-by-step explanation:
x x6=18
x=3
Answer:
(18=6 times x) you would divide both sides by 6 since inverse operations and to leave the x by itself. 18/6 is 3 so 3=x
What is a speed of 55 mph equivalent to in units of m/s? ( 1 mile = 1609 m, 1 hour = 3600 s)
9514 1404 393
Answer:
about 24.58 m/s
Step-by-step explanation:
Multiply by conversion factors that change the units, but not the value.
(55 mi/h) × (1609 m/mi) × (1 h)/(3600 s) = (55×1609/3600) m/s
= 88495/3600 m/s ≈ 24.58 m/s
_____
Additional comment
The exact conversion uses 1609.344 meters per mile, so gives exactly 24.5872 m/s.

Calculate the unit price per square foot for each of the flooring types listed above. Which flooring type costs the least per square foot?
a. carpet: $375 for 100 square feet
b. laminate: $340 for 80 square feet
c. vinyl: $402 for 120 square feet
Answer:
Vinyl
Step-by-step explanation:
The cost per square foot are is obtained by :
Total cost / total number of square feet
a. carpet: $375 for 100 square feet
Cost per square foot = $375 / 100
= $3.75 per sq ft
b. laminate: $340 for 80 square feet
Cost per sq ft = $340 / 80
= $4.25
c. vinyl: $402 for 120 square feet
Cost per sq ft = $402 / 120
= $3.35
Arranging from least to highest
Vinyl < carpet < laminate

What is the equation of a line with a slope of 3 and contains
point (4.1)
Answer:
y = 3x - 11
Step-by-step explanation:
y=mx+b
1=3(4)+b
1=12+b
b=-11
Answer:
y = 3x –11
or 3x – y = 11 Standard form
Explanation:
using slope-intercept form, calculate b
1 = 3(4) + b
1= 12 + b
1 –12 = b
–11 = b rewrite the equation using this value.
y = 3x –11

A store receives a shipment of 320 skateboard wheels. After 3 days, 272 of the skateboard wheels are left. After 7 days, 208 skateboard wheels are left.
a. Write an equation that represents the number y of skateboard wheels remaining after x days.
b. Use the linear equation to predict how many skateboard wheels will be left after 11 days.
c. After how many days should the store plan to receive a new shipment of skateboard wheels so they do not run out?
d. What does the slope of the equation represent? What does the y-intercept represent?
Answer:
[tex]y=-16x+320[/tex]
144
20 days
Change of the number of skateboards with respect to the change of days.
y intercept represents the total stock of the skateboard wheels.
Step-by-step explanation:
The points on the plane are [tex](3,272)[/tex] and [tex](7,208)[/tex].
Slope is given by
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{208-272}{7-3}\\\Rightarrow m=-16[/tex]
The equation of the line will be
[tex]y-y_1=m(x-x_1)\\\Rightarrow y-272=-16(x-3)\\\Rightarrow y-272=-16x+48\\\Rightarrow y=-16x+320[/tex]
The equation that represents the situation is [tex]y=-16x+320[/tex]
When the number of days is 11 we have [tex]x=11[/tex]
[tex]y=-16\times 11+320\\\Rightarrow y=144[/tex]
The number of wheels left after 11 day is 144.
When the shipment will run out [tex]y=0[/tex]
[tex]0=-16x+320\\\Rightarrow x=\dfrac{320}{16}\\\Rightarrow x=20[/tex]
So, after 20 days the shipment will run out.
The slope represents the change of the number of skateboards with respect to the change of days.
The y intercept represents the total stock of the skateboard wheels.

Find the function value f(3) if
f (h) = 4h – 3
Answer:
f(3) would be 9 in this case.
Step-by-step explanation:
To find the value f(3) if f(h) = 4h - 3, substitute h for 3.
f(3) = 4(3) - 3
Multiply 4 by 3 to get 12.
f(3) = 12 - 3
Subtract 3 from 12 to get 9.
f(3) = 9
f(3) would be 9 in this case.
Erin is 3 years younger than twice Alex's age. Their ages combined are 33 years. How old are Alex and Erin? Write a systems of equations first, let x=Erin's age and y=Alex's age
Answer:
X = 15 = Erin's age
Y = 18 = Alex's age
Step-by-step explanation:
X = Erin's age
Y = Alex's age
33 (combined ages) - 3 (how many years Erin is younger than Alex) = 30
30 ÷ 2 = 15
15 + 0 = 15 (Erin's age)
15 + 3 = (Alex's age)
X = 15 = Erin's age
Y = 18 = Alex's age
Check if I'm correct:
15 + 18 = 33
Sorry if wrong! Plz mark brainiest if correct :D Have a great day luv <3

Field 0.45 kilo long and 0.4 kilo wide. What is the area in square meters
Answer:
180000
Step-by-step explanation:
Answer:
180.000 m^2.
Step-by-step explanation:
Area in square kilometers
= 0.45 * 0.4
= 0.18
There 1000* 1000 = 1,000,000 square meters in a square kilometer so
Area in sq meters = 0.18 * 1000000
= 180,000 m^2.

Earning an A in algebra this semester is an example of (A) a long term goal.
One of the many branches of mathematics is algebra, which means "reunion of shattered pieces, setting of bones" in Arabic. Algebra, which is a common thread throughout practically all of mathematics, is essentially the study of mathematical symbols and the rules for using them in formulas.
Since all mathematical applications involve manipulating variables as though they were numbers, elementary algebra is a prerequisite. The study of algebraic structures like groups, rings, and fields is referred to as abstract algebra, primarily in educational contexts (the term is no more in common use outside educational context). Modern presentations of geometry include linear algebra, which deals with linear equations and linear translations, and has numerous real-world applications (in weather forecasting, for example).Since there are a wide variety of application for Algebra in our day-to-day lives and in the modern sciences, so a good score in Algebra will not only get a good score for the results but also help learn valuable information for the future. Hence it is a long-term goal.

D.75% of the stickers are stars.
E.The number of heart stickers is the same as the number of star stickers
The correct statement are;
B. Katarina has 375 star stickers.
D. 75% of the stickers are stars.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Katarina bought a package of 500 stickers. 25% of the stickers are hearts. The remaining stickers are stars.
Now,
Since, Katarina bought a package of 500 stickers. 25% of the stickers are hearts. The remaining stickers are stars.
Hence, The number of hearts = 25% of 500
= 25/100 × 500
= 25 × 5
= 125
And, Number of stars = 500 - 125
= 375
= 75% of 500
Thus, The correct statement are;
B. Katarina has 375 star stickers.
D. 75% of the stickers are stars.
