Answer:
Ratio of number of boys to girls= 2:3
Ratio of number of boys to girls to total number of children= 2:3:5
Step-by-step explanation:
42 boys and 63 girls took part in an art competition
The ratio of the number of boys to the number of girls can be calculated as follows
= 42/63
= 2:3
The ratio of the number of boys to girls to total number of children can be calculated as follows
= 42/63/105
= 2:3:5

When measuring the sides, triangles can be classified as acute, scalene and isoceles
Answer:
Yes, When measuring the sides, triangles can be classified as acute, scalene, and isosceles
Step-by-step explanation:
In any triangle, there are at least two acute angles
The types of triangles according to their angles are:
Acute-angled triangle ⇒ 3 angles are acuteRight-angled triangle ⇒ 2 acute angles and 1 right angleObtuse-angled triangle ⇒ 2 acute angles and 1 obtuse angleThe types of triangles according to their sides are:
Equilateral triangle ⇒ 3 equal sidesIsosceles triangle ⇒ 2 equal sidesScalene triangle ⇒ 3 different sideYou can classify the type of the triangle according to its angle using the measuring of its sides.
If a triangle has sides length a, b, c where c is the longest side
∵ a² + b² > c²
∴ The triangle is an acute-angled triangle
∵ a² + b² = c²
∴ The triangle is a right-angled triangle
∵ a² + b² < c²
∴ The triangle is an obtuse-angled triangle
You can classify the type of the triangle according to its sides using the measuring of its sides.
If a triangle has sides lengths a, b, c
∵ a, b, c have unequal lengths
∴ The triangle is scalene
∵ a and b or a and c or b and c have equal lengths
∴ The triangle is Isosceles
∵ a, b, c have equal lengths
∴ The triangle is equilateral
Yes, When measuring the sides, triangles can be classified as acute, scalene, and isosceles

A baseball player swings at the ball 56 times over a season and hits 16 times.
What is the ratio of hits to misses?
Answer:
2:5.
Step-by-step explanation:
Number of misses = 56 - 16 = 40.
Ratio = 16:40
- which simplifies to (16/8) : (40 / 8)
= 2:5.

Frank and Jasmine use the same trail for their Saturday walk. Frank walks at an average pace of 2 miles per hour. Jasmine starts when Frank is at the 3 mile marker and walks at an average pace of 4 miles per hour. Write an algebraic equation that could be used to determine how many hours Jasmine will walk before she catches up to Frank.
Answer:
Jasmine will walk 1hr:30min before she catches up to FrankStep-by-step explanation:
let the distance of the trail be x
and let the time be t
given that franks average speed is 2 miles per hour
the distance covered by Frank is x-3
the time taken by Frank to cover the distance is
we know that speed=distance/time
2=x-3/t
2t=x-3
x=2t+3---------1
Jasmine speed= 4 miles per hour
speed=distance/time
4=x/t
x=4t--------2
equating 1 and 2 above we have
2t+3=4t
solving for t we have
4t-2t=3
2t=3
t=3/2
t=1.5
That is 1hr 30 min

Clare is paid $90 for 5 hours of work. At this rate, how long will it take her to save $360?
Answer:
20 hours
Step-by-step explanation:
We can use a ratio to solve
90dollars 360 dollars
--------------- = -----------
5 hours x hours
Using cross products
90x = 5* 360
Divide each side by 90
90x/90 = 5 * 360/90
x = 20
20 hours

A hockey player strikes a hockey puck. The height of the puck increases until it reaches and maximum height of 3 feet, 55 feet away from the player. The height y (in feet) of a second hockey puck is modeled by y=x(0.15-0.001x), where x is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.
Answer:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.
Step-by-step explanation:
Maximum height of 3 feet is attained by the hockey puck of first player is when the puck is 55 feet away from the player.
It is at the mid point of the total horizontal distance to be traveled by the hockey puck.
So, the horizontal distance traveled by hockey puck of first player = 55 + 55 = 110 feet
Second player:
[tex]y=x(0.15-0.001x)[/tex]
where [tex]y[/tex] is the height of a second hockey puck
[tex]x[/tex] is the horizontal distance.
When the puck hits the ground, [tex]y=0[/tex]
Now, let us find the value of [tex]x[/tex].
[tex]\Rightarrow 0=x(0.15-0.001x)[/tex]
At [tex]x=0[/tex] feet or [tex]x=150[/tex] feet, [tex]y=0[/tex]
Therefore, the distance traveled by second hockey puck is 150 feet.
So, the answer is:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.

The graph represents how kyren spent her allowance this week. If her allowance was $20, how much did she spend on the spirit shirt
Answer:8 Dollars
Step-by-step explanation: The whole is 100 so you add 50 and 10 together which is the lunch and candy which equals 60 then you subtract the whole number 100 by 60 giving you 40 which is the percentage of 20 that was spent on the spirit shirt.And the way I do it is 10 percent of 20 is 2 so times 2 by 4 which gives you 8 dollars.

This is another way of saying "no solutions"
============================================
Explanation:
Your teacher made a typo. The given inequalities will have boundary lines that both have positive slopes, not negative slopes. So the boundary lines should go uphill as you move from left to right.
See the diagram below to see what the graph should look like.
The upper dashed line is y = (1/2)x+3. The lower dashed line is y = (1/2)x-2
The upper dashed line represents the boundary for y > (1/2)x+3. Region 1 is the set of solution points for y > (1/2)x+3
While the solution set for y < (1/2)x-2 is represented with region 3
There is no overlap between regions 1 and 3 due to the parallel boundary lines.
Put another way: there are no (x,y) points that are in both region 1 and region 3 at the same time.
So that's why there are no solutions to this system of inequalities.
---------------------
Alternative method:
Convert the first inequality into Ax+By > C form
y > (1/2)x+3
2y > x + 6 .... multiply both sides by 2
-x+2y > 6 ... subtract x from both sides
z > 6 .... let z = -x+2y
Convert the second inequality into Ax+By < C form
y < (1/2)x-2
2y < x - 4
-x+2y < -4
z < -4 .... let z = -x+2y
We have some number z that is both z > 6 and z < -4 at the same time, but no such number exists. So this is another way to see we have an inconsistent system with no solutions.
