Answer:
15 students suggested a rainbow-themed party.
25 students did not suggest a rainbow-themed party.
Step-by-step explanation:
40 students
3 out of every 8 students suggested rainbow them
40/8 = 5
5 groups = 40 students
1 group = 8 students
3 × 5 (amount of groups) = 15
15 students suggested a rainbow-themed party.
40 - 15 = 25
25 students did not suggest a rainbow-themed party.

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 4) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 4 = 20. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen fifths plus twenty-one quarters is one hundred seventy-three twentieths.
Answer:
Decimal: 5.4
Fraction: 5 2/5 or 27/5
Step-by-step explanation:
Decimal:
5 1/4 = 5.25
-3 2/5 = -3.4
5.25 + 3.55 - 3.4 (Simplified)
= 5.4
Fraction:
-3.55 = -71/20 or -3 11/20
5 1/4 + 3 11/20 - 3 2/5 (Simplified)
= 5 2/5
If it took 8 hours to mow 10 lawns, then at that rate, how many lawns could be mowed in 16 hours?
Answer:
You could mow 20 yards in 16 hours.
Step-by-step explanation:
You can mow 20 yards in 16 hours because half of 16 is 8 and in the question it says that it took 8 hours to mow 10 yards and 8x2=16 so if you multiply 10 by 2 then you would get your answer, 20 yards.
Answer:
20
Step-by-step explanation:
we can find it by using proportions which is the harder way
16/8=x/10
16(10)=8x
160=8x
/8. /8
20=x
20 lawns
The easiest way is that was know 10 lawns is from 8 hours and if we divide 16 by 8 we get 2 so we just have to multiply the 10 lawns by 2 to get 20

A. The perimeter is 4.1 times the perimeter of Triangle 1, and the area is 4.1 times the area of Triangle 1.
B. The perimeter is 8.2 times the perimeter of Triangle 1, and the area is 8.2 times the area of Triangle 1.
C. The perimeter is 4.1 times the perimeter of Triangle 1, and the area is 16.81 times the area of Triangle 1.
D. The perimeter is 16.4 times the perimeter of Triangle 1, and the area is 16.81 times the area of Triangle 1,
Answer:
it's A
mark me as brainiest please
The correct statement about the area and perimeter of Triangle 2 is true are,
⇒ The perimeter is 4.1 times the perimeter of Triangle 1, and the area is 16.81 times the area of Triangle 1.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
Triangle 1 is dilated by a scale factor of 4.1 using the origin as the center of dilation to create Triangle 2.
Now, We get;
The Triangle 1 is dilated by a scale factor of 4.1 using the origin as the center of dilation to create Triangle 2.
Hence, The perimeter of triangle 2 is 4.1 times the perimeter of Triangle 1.
And, We know that;
Area of triangle = 1/2 x Base x Height
So, The area of triangle 2 is 16.81 times the area of Triangle 1.

Convert 150 pounds to kilograms. (1 pound = 0.454 kilogram)
68.1 kilograms
6.81 kilograms
681 kilograms
0.00681 kilogram
At the conversion rate, 1 pound = 0.454 kilograms, 150 pound is 68.1 kilograms.
What is multiplication?The mathematical operation of multiplication is arithmetic. Additionally, it involves repeating the same forms of statements.
Given, conversion rate
1 pound = 0.454 kilograms
To covert the n pounds:
n x 1 pound = n x 0.454 kilograms
Here, we have n = 150
150 x 1 pound = 150 x 0.454 kilograms
150 pounds = 150 x 0.454 kilograms
150 pounds = 68.1 kilograms
Therefore, 150 pounds = 68.1 kilograms.

Hi! I need help with transversals of parallel lines solve the x if someone can help it would be great! Thank you!
Step-1: Find a property that shows the relation between the two angles
Given Information:
Line IJ and Line KL are parallel lines.∠KNH = 30x - 15∠GMJ = 25xIf Line IJ and Line KL are parallel lines (cannot intersect), both angles are outside the parallel lines, but each angle is on the opposite side of the transversal, the angles verify a property called the external angle property. The external angle property is called "external" because both angles are outside the transversal (a line that intersects the parallel line).
Step-2: Write an equation that describes the two angles
Since ∠KNH and ∠GMJ support the external angle property, we can assume that the two angles are equivalent. Therefore, we can write the following equation that can describe the relation between the angles:
⇒ ∠KNH = ∠GMJ ⇒ 30x - 15 = 25x
Step-3: Solve for x (common variable between two angles)
To find the measure of ∠KNH, we must find the value of x. This can be done by solving for the x-variable in the equation created from above knowledge. Simplify isolate all the variables on one side of the equation, simplify if needed, and isolate the coefficient if needed. We can isolate the variables on one side by adding or subtracting both sides of the equation. Then, we can cancel out the coefficient (a number being multiplied by the variable). from the variable by multiplying/dividing both sides of the equation.
⇒ 30x - 15 = 25x⇒ 30x - 15 - 30x = 25x - 30x (Isolating the variables on one side)⇒ -15 = 25x - 30x = -5x⇒ -15 = -5x ⇒ x = -15/-5 = 3Step-4: Substitute the value of x and determine the measure of ∠KNH
Now, we can substitute the value of x into the angle measure. We have the following angle measure of ∠KNH ⇒ (30x - 15)°. So, we have:
⇒ 30x - 15 = 30(3) - 15 = 75°Therefore, the measure of ∠KNH is 75°.
