Answer:
45000 m
Step-by-step explanation:
Speed = distance / time
10 km/h = distance / 4.5 hours
distance = 10 x 4.5 = 45 km
Kilometre needs to be converted to metres
Ikm = 1000m
45 x 1000 = 45,000m
Anthony has 400 marbles. He sells 1/4 of the marbles to Jayveon, he gives 10% to Abdul and donates 10 marbles to his little brother's collection. Explain in writing (typing) how to find the number of marbles each person received then explain how to find the number of marbles Anthony has left. (Remember to write 5 or more complete sentences.)
help me please
Answer: See explanation
Step-by-step explanation:
Number of marbles = 400
Anthony sells 1/4 of the marbles to Jayveon. This will be:
= 1/4 × 400
= 100 marbles
Anthony gives 10% to Abdul. Abdul will have:
= 10% × 400
= 0.1 × 400
= 40 marbles
He gave 10 marbles to his little brother.
The number of marbles that Anthony has left will be:
= 400 - (100 + 40 + 10)
= 400 - 150
= 250 marbles

A company buys a digital scanner for $12,000.
The value of the scanner is $12,000 (1 - n/5 ) after years.
The
company has budgeted to replace the scanner when the trade-in value is $,400.
After how many years should the
company plan to replace the machine in order to receive this trade-in value?
Answer:
it will be n=4
Step-by-step explanation:
12,000 1-n/5 =2,400n
12000-12000=2,400
2,400-12000=-9600

Select all equivalent
equations for the translation of "four times the sum of
a variable and nine equals eighteen".
4+ (x + 9) = 18
4(x)(9) = 18
4(x + 9) = 18
4x + 4(9) = 18
4x + 9 = 18
Answer:
No - 4+ (x + 9) = 18
No - 4(x)(9) = 18
Yes - 4(x + 9) = 18

Una persona ahorra todos los meses el mismo monto de dinero durante 1 año. Si luego de este tiempo reunió $243.000 ¿Cuánto dinero guardo cada mes?
Answer:
Ahorro por mes= $20.250
Step-by-step explanation:
Dada la siguiente información:
Ahorro total= $243.000
Número de meses= 12
Voy a suponer que empeza a ahorrar desde los cero $.
Debemos usar la siguiente formula:
Ahorro por mes= ahorro total / número de meses
Ahorro por mes= 243.000 / 12
Ahorro por mes= $20.250
What is the slope of the line?
Answer:
2/1
Step-by-step explanation:
Slope can be found by using rise/run
in other words count the number of spots rising up then move to either left or right (up and to the right in this case)
yes the slope could be -2/1 from a reflective point. Rise/Run pov or positive pov it's 2/1
Answer:
the slope is 2
Step-by-step explanation:
it crosses the point (-2, -4), which from there to the next crossing coordinate (-1, -2), it goes up +2 units on the y-axis and goes to the right on the x-axis +1 units

A rectangular tank measures 14 cm by 9 cm by 10 cm. What is the volume of the tank in cubic centimeters?
What us the measure of the missing angle?
Answer:
None of them
Step-by-step explanation:
Because 30+135+45 add up to 210 then if you add 30, or 45 degrees it will be more than 180 degrees. If you subtract -15 from 210 you will get 195 which is still not right. So the best answer is none of the above
Hope this helps
answer anybody ? i can’t do math to save my life lol
Answer:
[tex]x = 10[/tex]
Step-by-step explanation:
To make A and B parallel, the two angle measures will have to be congruent, or equal. To show this, we can write an equation. Then, we can solve for x.
[tex]4x = 3x + 10[/tex]
Subtract 3x.
[tex]4x - 3x = 3x + 10 - 3x[/tex]
Simplify.
[tex]x = 10[/tex]

what is the equation of a line with a slope of -1/3 passes through the point (6,5)
Answer:
y - 5 = -¹/₃(x - 6)Step-by-step explanation:
Slope intercept form: y - y₁ = m(x - x₁)
m = -¹/₃
(6, 5) ⇒ x₁ = 6, y₁ = 5
The equation:
y - 5 = -¹/₃(x - 6)

In triangle ABC, where triangle B is the right angle, side AB has a length of 6 cm and side BC has a length of 10 cm. What is the length of side AC? A. 4 cm B. 6 cm c. 11.66 cm D. 8 cm
Answer:
11.66cm (c)
Step-by-step explanation:
Apply the phuthagorean theorem
Side opposite to the right angle in triangle is AC
AC²=ab²+bc²=10²+6²=100+36=136
We need AC so take the square root of 136 which is 11.66 as the answer

You have to write a equation
Answer:
y = 3 sin 4x
Step-by-step explanation:
For y = a sin bx,
a is the amplitude which is the crest of the graph. In this case a = 3 from the given graph.
Now, b is associated with the period where; b = 2π/period
From the graph the period which is the time between where the graph crosses the x-axis = π/2
Thus; b = 2π/(π/2)
b = 4
Thus,equation is; y = 3 sin 4x
