This year, there was 40% more snow than last year. The amount of snow this year is 140% of the amount of snow last year.
1. This year, there were 25% fewer sunny days than last year. The number of sunny days this year is (BLANK)% of the number of sunny days last year.
2. Compared to last month, there was a 50% increase in the number of houses sold this month. The number of houses sold this month is (BLANK)% of the number of houses sold last month.
3. The runner’s time to complete the marathon was 10% less than the time to complete the last marathon. The runner's time to complete the marathon was (BLANK)% of the time to complete the last marathon.
PLEASE FILL IN THE BLANKS. This is in fact the full question
Answer:
75%150%90%Step-by-step explanation:
You want the percentage multiplier associated with the following changes:
25% decrease50% increase10% decreaseMultiplierTo find the multiplier, add 1 to the change. When you want the multiplier in percent, then add 100% to the change expressed as a percent. (1 = 100%)
1. 25% fewer100% -25% = 75% . . . . of last year
2. 50% increase100% +50% = 150% . . . . of sales last month
3. 10% less100% -10% = 90% . . . . of last marathon's time

Answer:
90
Step-by-step explanation:
each dot = 45 bc 540 / how many dots there are which is 12 = 45 then there are 2 dots worth of 45 making it 90
math
540/12=45
45 x 2 = 90
Answer: 135 students
Step-by-step explanation:
1. Divide 540 (total number of students) by the number of dots (12)
2. So then 540/12= 45
3. Then see how many dots are more then 5 miles away so that is 3 dots (2dots on 6 miles, and 1 dot on 7 miles)
4. After 45*3= 135
If sin A = 28 53 sinA= 53 28 and cos B = 3 5 cosB= 5 3 and angles A and B are in Quadrant I, find the value of tan ( A + B ) tan(A+B).
Answer:
[tex]Tan(A+B)=\frac{264}{23}[/tex]
Step-by-step explanation:
From the question we are told that:
[tex]SinA=\frac{28}{53}[/tex]
[tex]CosB=\frac{3}{5}[/tex]
Let X be the adjective side to A
Let Y be the opposite side to B
Generally the equation for X is mathematically given by
[tex]X^2=\sqrt{53^2-28^2}[/tex]
[tex]X=45[/tex]
Therefore [tex]TanA[/tex]
[tex]TanA=\frac{28}{45}[/tex]
Generally the equation for Y is mathematically given by
[tex]Y^2=\sqrt{5^2-3^2}[/tex]
[tex]Y=4[/tex]
Therefore [tex]TanB[/tex]
[tex]TanB=\frac{4}{3}[/tex]
Generally the equation for [tex]Tan(A+B)[/tex] is mathematically given by
[tex]Tan(A+B)=\frac{TanA+TanB}{1-TanA*TanB}[/tex]
[tex]Tan(A+B)=\frac{\frac{28}{45}+(\frac{4}{3})}{1-(\frac{28}{45})*(\frac{4}{3})}[/tex]
[tex]Tan(A+B)=\frac{264}{23}[/tex]

Which best describes the relationship between the two triangles below?
Triangle M N L. Angle M is 51 degrees and angle L is 36 degrees. Triangle F H G. Angle F is 51 degrees and angle G is 36 degrees.
Triangle M L N is similar to Triangle F G H because of the third angle theorem, Angle M is congruent to angle F, Angle L is congruent to angle G, and Angle N is congruent to angle H.
Triangle M L N may or may not be similar to Triangle F G H because the third angle is unknown.
Triangle M L N is similar to Triangle F G H because of the angle-angle criterion, Angle M is similar to angle F, Angle L is similar to angle G, and Angle N is similar to angle H.
Triangle M L N may or may not be similar to Triangle F G H because the side lengths are unknown.
Answer:
Triangle M L N is similar to Triangle F G H because of the third angle theorem, Angle M is congruent to angle F, Angle L is congruent to angle G, and Angle N is congruent to angle H.
Step-by-step explanation:
Triangles are similar if all of the angles are congruent and corresponding to the other triangle and the sides are proportionate. It is important to note that if the angles are congruent then the sides must be proportionate; so, the side lengths are not necessary. Additionally, the third angle theorem states that if two known angles are congruent then the third angles must also be congruent. So, the two triangles must be similar because all of the angles are congruent to their corresponding angles.
Does 9 12 15 make a right triangle?
The side lengths measuring 9 units , 12 units and 15 units make a Right Triangle because the sides satisfy the condition of the Pythagoras Theorem .
According to the Pythagoras Theorem , which states that square of the lonest side (hypotnuse) is equal to the sum of the square of the other two sides ( perpendicular and Base) ,
The side lengths of right triangle are = 9 units , 12 units and 15 units ,
According to the condition of Pythagoras theorem , [tex]15^{2} = 12^{2} + 9^{2}[/tex]
On simplifying ;
we get ;

put this equation in Slope-Intercept form
Y + 2 = -5 ( X + 3 )
Answer: y=-5x-17
Step-by-step explanation:
Slope-intercept form follows the formula y-mx+b, where m is slope and b is y-intercept. All we have to do is to manipulate the equation to look like y=mx+b.
[tex]y+2=-5(x+3)[/tex] [distribute right side]
[tex]y+2=-5x-15[/tex] [subtract both sides by 2]
[tex]y=-5x-17[/tex]
Now, our equation matches y=mx+b with m=-5 and b=-17.

A cleaning company charges a fixed amount for a house call and a second amount for each room it cleans the total cost to clean six rooms is $250 and the total cost to clean eight rooms is $320 how much would this company charge to clean two rooms
The cleaning company would charge $150 for cleaning two rooms according to the fixed charges.
What is fixed amount?A fixed amount is a fixed amount or amount established by agreement or contract. This amount is usually a specified amount, does not change over time, and is usually paid on demand or by a certain date. Fixed amounts are commonly used in loans, insurance, and other financial contracts.
This cost is calculated by dividing the difference between the total cost of 6 and 8 rooms by the number of rooms cleaned (6 - 2 or 4).
= ($250 - $320)/4
= $40
This will give you a price of for each additional room.
To calculate the cost of two rooms, simply add the fixed amount of the home visit and double the cost ($40) for each additional room. That's a total of $150 for two rooms.

Therefore , the solution of the given problem of area comes out to be the land acquired by university is of 3 miles square area.
Define area.The term "area" describes the amount of space occupied by a 2D form or surface. We use cm2 or m2 as our units for measuring area. A shape's area is determined by dividing its length by its breadth.
Area = length x breadth.
Here,
Given : A triangle land which has
height = 2miles
and base = 1.5+ 1.5 = 3 miles
Thus,
To find the area of triangle :
=> Area = 1/2*b*h
=>Area = 3*2/2
=> Area = 3 miles square
Therefore , the solution of the given problem of area comes out to be the land acquired by university is of 3 miles square area.
