Answers
Answer:
1. a. 544%
b. 84%
2. 175
3. $867.18
Step-by-step explanation:
1. a.2.32-0.36=1.96
1.96/0.36=5.44
5.44*100=544
b. 1.96/2.32=0.84
0.84*100=84
2. let x = # of 7th graders
let y = # of 8th graders
y is 125% of x
y=1.25x
x=140
y=1.25*140
y=175
3. A=P(1+r)^t
A=700(1+0.055)^4
A=867.18

Helpp!! Is about angles!!! Please help!
Answers
Answer:
Triangle WRD's angles are all 60 degrees, angle W and angle R and angle D.
Triangle WRD is an equiangular, equilateral triangle. It is also an acute triangle, as all angles are less than 90 degrees.
Step-by-step explanation:
You are told that WRD has all equal sides, each 3 inches long.
In a triangle, if sides are equal, then the opposite angles are also equal. So if ALL the sides are equal, then ALL the angles are equal.
The sum of the interior angles in a triangle is always 180 degrees. Since the trhee angles are all equal and they must add up to 180 degrees, 180/3 =60, so the angles must all be 60 degrees.
Triangle are classified by sides as
*** scalene = no equal sides
*** isosceles = two equal sides
*** equilateral = all equal sides
Triangles are classified by angles as
*** right triangle = one 90 degree angle
*** obtuse triangle = one angle larger than 90 degrees
*** acute triangle = all angles less than 90 degrees
*** equiangular = all angles equal
There can be overlap in the categories, like an acute triangle also being equiangular.
Adjust the number into correct standard form.

The equation h=60-4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain
Answers
Answer:
40m
Step-by-step explanation:
Complete question
The equations h = 60 - 4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain. How high is the water after 5 minutes.
To get the height of the water after 5minutes, we will find h at when m = 5
h = 60 -4 (5)
h = 60 - 20
h = 40m
Hence the water is 40m high after 5minutes

(2)
Total marks: 5
Answers
Answer:
Please check explanations for answer
Step-by-step explanation:
Firstly, we need all the probability in the same decimal form
P(A) = 0.66
P(B) = 0.067
P(C) = 2/3 = 0.67
P(D) = 60/100 = 0.6
a) The least likely is the smallest value of decimal
This is 0.067 which is for coin B
most likely is the highest probability; this is C which is 2/3
b. Probability that D will land on tail is 1 - probability that it lands on head
= 1 - 0.6 = 0.4
c. Mathematically that is the product of the probability and the number of times it was thrown
That will be;
0.066 * 4000
= 264 times

Answers
Answer:
option d.
let the two angle of mnp be x and y
in the trapezoid NO and MP are parallel.
so the 28° = y and 42°=x(by alternate interior angle)
so the angle mnp= x+y
angle mnp=28°+42°=70°
