Answer:
M=2/3
m=1/2
Step-by-step explanation:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.[1] Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844)[2] who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (1888)[3] who wrote it as "y = mx + c".[4]
Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line. A line that is decreasing has a negative "rise". The line may be practical - as set by a road surveyor, or in a diagram that models a road or a roof either as a description or as a plan.
The steepness, incline, or grade of a line is measured by the absolute value of the slope. A slope with a greater absolute value indicates a steeper line. The direction of a line is either increasing, decreasing, horizontal or vertical.
Jessie's school has 570 students. Thirty percent of the students are eighth-graders. One-third of eighth-graders walk to school. How many eighth-graders walk to school?
Answer:
57
Step-by-step explanation:
10% of 570 = 57 (dividing by 10). Times that by 3, which is 171. Now divide 171 by 3, equals 57 (the answer).

Step-by-step explanation:
Both triangles are shown are similar. Therefore, the ratio of their sides will be maintained. We can then set up the following proportion:
[tex]\frac{2}{11}=\frac{3}{3+x},\\2(3+x)=33,\\(3+x)=16.5,\\x=\boxed{13.5\text{ or }\frac{27}{2}}[/tex]
The lateral area of a regular pentagonal pyramid is 75 square inches and the slant height is 10 inches. Find the length of each side of the base.
A) 15 in.
B) 14 in.
C) 7.5 in.
D) 3 in
The length of each side of the base is 3 inches. Thus, the correct option is D.
What is the pyramid?In terms of geometry, a pyramid is a polygon that is created by joining an apex and a polygonal base. A triangle known as a lateral face is formed by each base edge and apex. If the base of the pyramid is a rectangle then the pyramid is known as a rectangular pyramid.
The lateral area of a regular pentagonal pyramid is 75 square inches and the slant height is 10 inches.
The length of each side of the base is calculated as,
75 = 5 x 1/2 x a x 10
75 = 25a
a = 3 inches
Thus, the correct option is D.

A school has an equal amount of boys and girls. You use a coin to simulate the first three students to arrive at school each day, where "heads" represents a boy and "tails" represents a girl. The table below shows a sample of 20 coin tosses
Find the the experimental probability that the first three students that arrive at school are boys.
No links please! I will reward brainliest for the correct answer. Thanks.
Answer:3/20
Step-by-step explanation:
Heads=Boy
Tails=Girl
If the first 3 students are boys, all 3 coins must be heads.
Because in 3 of these experiments, the coins all land on heads, and there are 20 experiments completed, 3 out of the 20 experiments are 3 boys; 3/20.

Answer:
a is the answer
Step-by-step explanation:
y = ( x^2 +2x+ 5 )^6,
let u be equal to x^2 + 2x + 5
y = u^6 '
dy|du = 6u^5, du|dx = 2x + 2
dy|dx = dy|du × du|dx = 6u^5 ×( 2x + 2 )
= 2( x + 1) × 6u^5 = 12 ( x + 1 )( x^2 + 2x +5)^5
the attendance at an athletics meeting is 14000. If 68% are men and boys and 22% are women, how many are girls
Answer:
1400 girls
Step-by-step explanation:

22% of 14,000= 3,080
9,520 + 3,080 =12600
14,000 - 12,600 = 1400 girls

find the measure of the angle indicated for each trapezoid
Answer:
The trapezoid is a quadrilateral. The 4 angles of a quadrilateral all equal to 360 degrees. Now you know that this is an isosceles trapezoid since the two sides are congruent. [360-(110*2)] / 2= [360-220] / 2= 140/2=70. So the answer is 70 degrees.

The population of Florida in 2000 was 15,982,378 and the land area was 54,252 square miles. The population increased 26.8% by 2015. To the nearest whole number, how much did the population density, in people per square mile, increase from 2000 to 2015?
Answer: See explanation
Step-by-step explanation:
Population in 2000 = 15,982,378
Land area = 54,252 square miles
The population density in 2000 will be:
= Population / Land area
= 15982378 / 54,252
= 294.60people per square miles
Since the population increased by 26.8% in 2015, the population in 2015 will be:
= 15,982,378 × (100% + 26.8%)
= 15,982,378 × 126.8%
= 15,982,378 × 1.268
= 20,265655
The population density in 2015 will be:
= Population / Land area
= 20,265655 / 54,252
= 373.55 people per square miles
The increase in population density from 2000 to 2015 will be:
= 373.55 - 294.60
= 78.95
