Answer:
4:10 p.m.
Step-by-step explanation:
4:50 p.m.
60 minutes in an hour
4:50 - 40 = 4:10
Answer:
4:10pm
Step-by-step explanation:
If he left 40 minutes ago and arrived at 4:50pm, then we must subtract the 40 minutes from the time, 4:50pm.
Remember we are subtracting minutes, not hours so we will only subtract from the minutes on the time, which displays 50.
50 - 40 = 10
4:10pm
Sofia and Diego drive to work. Sofia drives 72 miles in 1.5 hours. Diego drives 126 km in 2 hour 30 min. Work out the difference between their average speeds in km/h. 1 mile = 1.6 km
Answer:
26.4 km/hr
Step-by-step explanation:
Sofia and Diego drive to work.
For Sofia
We convert miles to km
Sofia drives 72 miles in 1.5 hours.
1 mile = 1.6 km
72 miles = x
x = 72 × 1.6 km
x = 115.2 km
We find the speed in km/hr
Speed = Distance /Time
= 115.2km/1.5 hours
= 76.8 km/hr
For Diego
Diego drives 126 km in 2 hour 30 min.
Speed = Distance/Time
Time = 2 hour 30 min = 2.5 hours
Speed = 126km/2.5 hours
= 50.4 km/hr
The difference between their average speeds in km/h is calculated as:
76.8 km/hr - 50.4 km/hr
= 26.4 km/hr

2x + 2= -3
What is the answer
Answer:-1/2
Step-by-step explanation:2x + 2 = -3 Subtract 2 on both sides so the equation would then be 2x + -1. Then you put 2x over 1 as a fraction then u flip the fraction which would be called reciprocal then multiply -1 times 1/2x which equals -1/2 and as a decimal it would be - 0.5
Name two points on the line y = 6x. Does it describe a
proportional relationship?
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.

Your family plans to start a small business in your neighborhood. Your father borrows $10,000 from the bank at an annual interest rate of 8% rate for 36 months. What is the amount of interest he will pay on this loan? (use Interest = Principal × Rate × Time)
Answer:
$2400
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year,
putting time into years for simplicity,
36 months ÷ 12 months/year = 3 years,
then, solving our equation
I = 10000 × 0.08 × 3 = 2400
I = $ 2,400.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 8% per year
for 3 years (36 months) is $ 2,400.00.
When multiplying a binomial by a trinomial, is the degree of the product
always 5? Explain.
Given that a binomial is multiplied by a trinomial.
A binomial means containing two terms normally
x+a
Trinomial is containing 3 terms may be
ax^2+bx+c
When we multiply we can get degree 3 also as shown above.
Hence the statement is false.
When a binomial is multiplied by a trinomial getting a product of degree 5 is only occasional and not always.

We know by using Pythagoras theorem
b = √h² - p²
= √ 15² - 10²
= √ 125
= 5√5
Hope it will help :)
Answer:
≈11.2
Step-by-step explanation:
a²+b²=c²
10²+b²=15²
100+b=225
-100 on both sides
b= √125= 11.2

Enter the measure of ZCAB to the nearest hundredth degree.
Step-by-step explanation:
sinA=p/h
sinA=12/15
A=sin-¹(4/5)=53.13=53°
<CAB=53°
The measure of ∠CAB is 53°.
What is Trigonometry?The trigonometric function, which comprises the sine, cosine, tangent, cotangent, secant, and cosecant, is one of the six mathematical operations used to describe the side ratios of right triangles (csc).
As per the given data:
From the given diagram, we can clearly understand that the triangle is a right-angled triangle which is right-angled at C.
We have to find out the measure of ∠CAB.
The lengths of the sides BC and AB is also given in the diagram.
For finding out the measure of ∠CAB we can consider BC as the perpendicular and AB as the hypotenuse, and then we have to use the appropriate trigonometric ratio.
The length of the perpendicular BC = 12 units
The length of the hypotenuse AB = 15 units
For relating perpendicular and hypotenuse, we can use the sin trigonometric ratio.
sinθ = Perpendicular / Hypotenuse
sinθ = BC / AB
sinθ = 12 / 15
sinθ = 4 / 5
θ = 53°
The measure of ∠CAB is 53°.
Hence, The measure of ∠CAB is 53°.

The volume of the cone will be 2120 cm³, i.e. option B.
What is volume ?Volume is the amount of space that something contains or fills.
volume of the cone [tex]=\frac{1}{3} \pi r^{2} h[/tex]
We have,
Height = 9 cm,
Radius = 15 cm
So,
volume of the cone [tex]=\frac{1}{3} \pi r^{2} h[/tex]
i.e.
volume of the cone [tex]=\frac{1}{3} * 3.14 * 15^{2} * 9[/tex]
On solving we get,
Volume of the cone = 2119.5 = 2120 cm³
Hence, we can say that the volume of the cone will be 2120 cm³, i.e. option B.

There are 12 players on a softball team. The coach has $605 to buy bat bags for all of the players. Each bat bag costs $55. Use the drop-down menus to explain whether the coach has enough money to buy a bat bag for each player... NEED ANSWERS ASAP
Answer:
Yes, he does.
Step-by-step explanation:
55 x 12 = 600
No, The coach does not have enough money to buy a bat bag for each player.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
There are 12 players on a softball team.
The coach has $605 to buy bat bags for all of the players.
Each bat bag costs = $55
Now,
Since, There are 12 players on a softball team.
And, Each bat bag costs = $55
So, The total cost of bag for 12 players = $55 x 12
= $660
Since, The coach has $605 to buy bat bags for all of the players.
And, $605 < $660
Thus, The coach does not have enough money to buy a bat bag for each player.
