Answer:
Yes he's correct
Step-by-step explanation:
5 goes into both 10 & 25
10 divided by 5 is 2
25 divided by 5 is 5
So 2/5 is the lowest it'll go
Yes, Tony is correct.
Here,
Lila rewrote 10/25 as 40/100 and represented it with the given picture.
And, Tony thinks this fraction is also equal to 2/5.
We have to find that, Tony is correct or not.
What is Fraction?
Fractions represent the parts of a whole or collection of objects.
Now,
In this picture there are total 25 square and shaded squares are 10.
So, it can be written in form of fraction as;
[tex]Fraction = \frac{Number of shaded squares}{total number of squares} =\frac{10}{25}[/tex]
Since, Lila rewrote 10/25 as 40/100 and represented it with the given picture.
And, Tony thinks this fraction is also equal to 2/5.
Then, we have to get the fraction = 10/25
After simplifying the fraction we get;
[tex]\frac{10}{25} = \frac{2}{5}[/tex]
Hence, Tony is correct.

Answer:
5√5
Step-by-step explanation:
Hypotenuse (h) = 15
perpendicular (p) = 10
base (b) = ?
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
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
The angles shown are supplementary. What is the value of x ?
Answer:
D
Step-by-step explanation:
This is because if u subsitute x with 17, 17x5 is 85 and 85+95= 180
[tex]\color{plum}\tt\bold{(D) \: 17}[/tex]
○=> Steps to derive correct answer :Given :
▪︎Angle (5x)° and angle 95° are supplementary angles.
Which means :
[tex] = \tt5x + 95 = 180[/tex]
[tex] = \tt5x = 180 - 95[/tex]
[tex] = \tt5x = 85[/tex]
[tex] \hookrightarrow\tt \color{plum}x = 17[/tex]
Thus, the value of x = 17
Let us check whether or not we have found out the correct value of x by placing 17 in the place of x:
[tex] =\tt5 \times 17 + 95 = 180[/tex]
[tex] =\tt 85 + 95 = 180[/tex]
[tex] =\tt 180 = 180[/tex]
Since the sum of both angles is equivalent to 180[85+95=180], we can conclude that we have found out the correct value of x.
Therefore, the correct option is (D) 17

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.

Step-by-step explanation:

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°.

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.
