susan ate 3/8 of a pan of brownies. Which decimal represents the amount of brownies left?
A 0.375
B 0.625
C 0.325
D 0.675
Answer:
B 0.625
Step-by-step explanation:
8/8-3/8=5/8
5/8=0.625
Answer:
B
Step-by-step explanation:
First you have to find how much 1/8 is as a decimal, which is 0.125. Multiply 0.125 by 3 to get 3/8 or add it 3 times which gives you 0.375. That knocks out 2 answers already A and C because it's asking how many brownies are left. You can either subtract 0.375 from 1 or you can do an easier way. .075 + 0.25 = 0.1, so it can't be D because it would be over 1 pan of brownies which leaves you with B. B is your answer.

Answer:
y=x-4
Step-by-step explanation:
Writing this in slope-intercept form or y=mx+b.
y = y coordinate
m = slope
x = x coordinate
b = y intercept (where the line intercepts on the y axis)
The slope is 1 because it's moving up and if you move over 1 unit to the right, then 1 unit up, you would cross another point. The y-intercept is -4 because that's where the line intercepts the y-axis.
Hence, the equation would be y=x-4
Note: I did not have y=1x-4 because 1x is the same as x.

What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Since in the given circle EB is the diameter, therefore, the measure of ∠EOB will be 180°.
Given the measure of ∠BOD is 90°, while the measure of arc DC is 50°. Therefore, the measure of ∠COD is 40°.
Thus, the measure of Arc EBC is the sum of ∠EOD and ∠COD, therefore, the measure of the Arc EBC is 220°

The length of line segment bc is 3 cm. Thus, the correct option is B.
What is a perimeter?Perimeter is the sum of the length of the sides used to make the given figure.
Since ACEG is a square and the perimeter of the square is 24 cm, therefore, the length of the side of the square is 6 cm.
Now, since the circle is inscribed in the square, therefore, each side of the circle will be divided into two equal parts by the circle. Thus, the value of BC is half the length of the side of the square.
BC = AC /2 = 6cm /2 = 3 cm
Hence, the length of line segment bc is 3 cm. Thus, the correct option is B.

People from two houses 9,000 feet apart are looking up at a plane that is BETWEEN them. House 1 is west of the plane has an angle of elevation of 17.5 degrees and house 2 is east of the plane and has an angle of elevation that is 18.8 degrees. How far is the plane from House 1?
The distance between the plane and house 1 is 4899.2 feet
How to determine the distance between the plane and house 1?See attachment for illustration of the question, where x represents the distance between the plane and house 1
Start by calculating the angle A using:
A = 180 - 17.5 - 18.8 ----- (angles in a triangle theorem)
This gives
A = 143.7
The distance x is then calculated using the following sine theorem
a/sin(A) = b/sin(B) = c/sin(C)
Using the parameters in the diagram, we have:
x/sin(18.8) = 9000/sin(143.7)
Multiply both sides by sin(18.8)
x= sin(18.8) * 9000/sin(143.7)
Evaluate
x = 4899.2
Hence, the distance between the plane and house 1 is 4899.2 feet
