temperature of the day. What was the temperature what was the temperature when Emily went
to the bed?
Answer:

Step-by-step explanation:
When she got up, the temperature was 58°F.
It rose 21°F, rose another 8°F, then drop 23°F
=> + 21 + 8 - 23
So, the temeperature when Emily went to bed was : 58 + 21 + 8 - 23 = 64°F

Explanation:
r = radius of the circle = 3
This is because segment IJ is 3 units.
Let's find the area of a full circle based on this radius.
A = pi*r^2
A = pi*3^2
A = 9pi
That's the area of a full circle with radius 3.
However, we only have a small pizza slice shaded. This slice has area of (1/2)pi or pi/2
If we divided the area of the slice over the full area, then we can figure out how many equal such slices make up the full circle.
(9pi)/(pi/2) = 9pi*(2/pi) = 18
This pizza has 18 slices total. Each slice has area pi/2 and it gives a total area of 18*(pi/2) = 9pi
The jump from pi/2 to 9pi is exactly "times 18" to represent the 18 slices.
--------------------
Since we now know that this pizza has 18 equal slices, we'll cut a full 360 degree rotation into 18 equal pieces
360/18 = 20
Therefore, the central angle KIJ is 20 degrees.
Plug this central angle, along with the radius, into the arc length formula
L = arc length
L = (circumference)*(angle in degrees)/360
L = (2*pi*r)*(20/360)
L = 2pi*9*(1/18)
L = pi
Arc KJ is exactly pi units long.
--------------------
Paraphrased another way:
The full distance around the circle is 2*pi*r = 2*pi*9 = 18pi units
However, we only want a slice of this perimeter. We divide by 18 because we found earlier that there are 18 equal slices.
So each slice has its curved portion, aka arc length, being (18pi)/18 = pi units

Factor the denominator
Answer:
B. (x+4)(x-4)
Step-by-step explanation:
We are given:
[tex]y=\frac{2x}{x^2-16}[/tex]
And asked to factor the denominator.
When factoring, you have a^2 + bx + c, and when wanting to turn it into a binomial, you have to find two numbers that multiply to c and add up to b.
In this case, we see that c is equal to -16. List out the factor of -16:
±1 , ±16
±2 , ±8
-4 , 4
Now we see that b is not present, therefore being 0. Our goal is to find two factors of -16 that will equal to 0 when added.
1 and 16 will never make 0
2 and 8 cannot make 0 either
4 and 4 can make 0, and since 16 is a negative number, one 4 needs to be negative while the other is a positive.
Basically stating, our factor of the denominator is:
[(x + 4)(x - 4)]
The class scores of a history test have a normal distribution with a mean Mu = 79 and a standard deviation Sigma = 7. If Opal’s test score was 72, which expression would she write to find the z-score of her test score? z = StartFraction 72 minus 79 Over 7 EndFraction z = StartFraction 72 minus 7 Over 7 EndFraction z = StartFraction 79 minus 72 Over 7 EndFraction z = StartFraction 7 minus 79 Over 7 EndFraction.
The value of z score for the history class test of Opal’s test score is negative one (-1).
What is normally distributed data?Normally distributed data is the distribution of probability which is symmetric about the mean.
The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
The z score for the normal distributed data can be given as,
[tex]Z=\dfrac{X-\mu}{\sigma}[/tex]
The mean value of the scores of history class is,
[tex]\mu=79[/tex]
The standard deviation value of the scores of history class is,
[tex]\sigma=7[/tex]
Here, the test score of the Opal’s is 72. Thus the z score for her test score can be given as,
[tex]z=\dfrac{72-79}{7}\\z=-1[/tex]
Hence, the value of z score for the history class test of Opal’s test score is negative one (-1).

The recipe says he needs 450 grams of rice for 6 people
how many kilograms of rice will he need for 18
Answer:
1.35kg
Step-by-step explanation:
450g : 6 people
x : 18 people
To get from 6 to 18, multiply by 3 so do the same to the other side
450 × 3 = 1350g
To convert from g to kg divide by 1000

45. A square has the same perimeter as a 5 x 11 rectangle. What is the area of the
square?
Answer:
The area of the square is = 64
Step-by-step explanation:
The perimeter of rectangle = Perimeter of the square
The rectangle has a length (l) of 11 and a width (w) of 5.
The perimeter of a rectangle = 2·l×2·w = 2×11+2×5 = 32
The perimeter of a square = 4·s => Since the perimeter of the rectangle = the perimeter of the square we can find out the side of the square by using the formula in bold.
The perimeter of the square = 4·s = 32
s = [tex]\frac{32}{4}[/tex] = 8
The area of a square is = s×s = s²
The area of the square is = s² = 8² = 64

Two angles of a triangle are 47 and 32 degrees. Select all angles that could represent exterior angles of a triangle.
Answer options:
101 degrees
79 degrees
152 degrees
133 degrees
Answer:
133, 79, 148 are ALL possible, so select 133 and 79
Step-by-step explanation:
Subtract 47 and 32 from 180 to find the third angle of the triangle (it is 101).
Then do 180-101 = 79
180-32=148
180-47=133
That tells you the exterior angle of each. Only two possible choices on your list.

PLEASE HELP ME. ONLY GOT 10 MINS.
Answer:
Step-by-step explanation:
The ratio of the angle is how the angle relates to each other. Let's say that we try to relate Angle A, B, C and get 1 : 3 : 5. That means Angle B is three times Angle A and Angle C is 5 times Angle A
Thus we get the equation:
A
B = 3A
C = 5A
A + B + C = 180, since all the angles of the triangle is equal to 180 degrees
A + 3A + 5A = 180
9A = 180
A = 20 --> B = 3A = 60 --> C = 5A = 100
So Angle A is 20 degrees, Angle B is 60 degrees, and Angle C is 100 degrees.

Answer:

Step-by-step explanation:
The two sides of the rectangle are 8 and 2, and the same can be said for the other two sides. This means to get the perimeter of the rectangle, we add:
8, 8, 2, and 2, which gets us 20.
This means that the perimeter of the square is also 20. Now we have to find the value of the sides.
To do this we can say that every side of the square is equal in length, and there are 4 sides.
All we need to do is take the perimeter, 20, and divide it by 4, which will give us our answer of 5 cm.
