Answer:
its 155
Step-by-step explanation:
360/2
180-25
155
The 155° angle in the piece that is left if the piece of cake with a 25° angle is eaten option (A) is correct.
What is a circle?It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have half of a circular cake is left after a party.
A piece of cake with a 25° angle is eaten.
We know the circle is a complete revolution of lines that joins from a fixed point to point at a certain distance; makes an angle 0f 360°
half of a circular cake with an angle = 360°/2 ⇒ 180°
25° angle piece eaten, then the remaining left portion:
= 180° - 25°
= 155°
Thus, the 155° angle in the piece that is left if the piece of cake with a 25° angle is eaten.

Step-by-step explanation:
the length of a rectangle is five inches less than three times its width . if the perimeter of the rectangle is 150 inches , find the dimensions.
Step-by-step explanation:
let x be the width of the rectangle.
given
length =
[tex]3x - 5[/tex]
inches.
also given Length + Width = 150 inches,
[tex]3x - 5 + x = 150 \\ 4x - 5 = 150 \\ 4x = 150 + 5 \\ 4x = 155 \\ x = 155 \div 4 \\ = 38.75in[/tex]
Since
Length = 3x-5 in
Width = x in,
Length = 3(38.75) - 5 = 111.25 in
Width = 38.75 in

I got it right on Edge Test
The function that depicts town that is growing in size are P = 1000 (1.08)^t and 1200 (1.185)^t
Expoenential functions
The standard exponential function is expressed as:
y = ab^x
The value of b will determine whether the towns are growing in size or not, For instance;
If b > 1 then the town is growing, else it is declining
From the given exponential functions, the function that depicts town that are growing in size are P = 1000 (1.08)^t and 1200 (1.185)^t

The model represents the quotient of two fractions.
Which equation does this model represent?
A. 5/6 ÷ 1/2 = 1 2/3
В. 2 1/2 ÷ 1/2 = 5/6
C. 5/6 ÷ 2 1/2 = 1/3
D. 2 1/2 ÷ 1/2 = 5
9514 1404 393
Answer:
D.
Step-by-step explanation:
The shaded portion of the three large rectangles is 2 1/2 of them. The divisions indicated by the fractions at the bottom are 1/2. The figure shows that 2 1/2 can be divided by 1/2 with the result that 1/2 goes into 2 1/2 five times.
This description seems to match the equation of choice D.

Step-by-step explanation:
triangle PQR is similar to triangle XYZ if PQ = n + 2, QR = n - 2 and XY=n^2 - 4, what is the value of YZ, in terms of n?
Answer:
(n-2)²
Step-by-step explanation:
If triangle PQR is similar to triangle XYZ, then;
PQ/QR =XY/YZ
Given
PQ = n + 2,
QR = n - 2 and
XY=n^2 - 4,
Substitute
n+2/n-2 = n²-4/YZ
n+2/n-2 = (n+2)(n-2)/YZ
1/n-2 = n-2/YZ
Cross multiply
YZ = (n-2)(n-2)
YZ = (n-2)²
Hence the value of YZ in terms of n is (n-2)²

A plane descends 1000 ft while flying
2.7 mi. What is the angle of descent?
Answer:
4.02°
Step-by-step explanation:
The angle of descent can be obtained using trigonometry ;
Since we have a right angled triangle ;
Let's use the relation:
Sin θ = opposite / hypotenus
Hypotenus = 2.7 miles
1 mile = 5280 feets
2.7 miles = (2.7 * 5280) = 14256 feets
Sin θ = 1000 / 14256
Sin θ = 0.0701459
θ = sin^-1(0.0701459)
θ = 4.0223674

Each student in her 8th grade math class presented her with a cookie. One-third of the students each gave her an oatmeal cookie, one-sixth of the students each gave her a cinnamon cookie, one-fourth of the students each gave her a chocolate chip cookie, and the remaining 9 students each gave her a peanut butter cookie. How many students are in Mrs Vo's 8th grade math class?
Answer:
36. There are 36 students in the class.
Step-by-step explanation:
4/12 oatmeal
2/12 cinnamon
3/12 chocolate
9 peanut
The fractions added together = 9/12
This means the 9 students = 3/12 of the class
3 x 4 = 12
9 x 4 = 36
