A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression
(0.85).32 represents the final price of the cake in dollars.
Answer:
$27.2
Step-by-step explanation:
A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression (0.85).32 represents the final price of the cake in dollars.
This is explained in the calculation below
= A cake that costs $32 is on sale for 15% off
The amount off the cake is calculated as
= 15% of $32
= 15/100 × 32
= $4.8
The amount he is paying for the cake =>$32 - $4.8
= $27.2
The above expression is obtained as
(0.85).32
= (100% - 15%) × 32
=( 1 - 0.15) × 32
= 0.85 × 32
= $27.2
The final price of the cake = $27.2

Ms. Hardy walks 12 meters in 24.7 seconds.
If she walks at this same rate, which of the
following is closest to the distance she will
walk in 5 minutes?
Answer:
she walks about 145.7 meters in 5 minutes
Step-by-step explanation:
Hey There!
so first we want to find the meters per second rate
to do this we do
[tex]\frac{12}{24.7} = 0.48582995951[/tex]
so the meters per second is 0.4858299591
Then we want to find how many seconds are in a 5 minutes
to do this we multiply 5 and 60
5x60=300
then we want to multiply that by the meters per second
300x 0.4858299591=145.748987854
so she walks about 145.7 meters in 5 minutes

Length=2(x-1)
Width=5
Area=length*width = (2(x-1))(5) = (2x-2)(5) = 10x-10

His reasoning is illogical because whether or not an expression has a term that is being subtracted isn't relevant; technically there are an infinite amount of ways to represent a value. Plus you can just compute the expressions and see that they're equal:
6x-2x+4 = 4x+4
4(x-1) = 4x+4
30
The two expressions are equal because when you compute the expression 4(n+3)-(3+n) , you get 3n+9:
4(n+3)-(3+n) = 4n+12-3-n = 3n+9
31
The two expressions are equal because when you compute the expression 2(2n-1), you get 4n-2.
2(2n-1) = (2)(2n)+(2)(-1)=4n-2

5(g+14)=(5)(g)+(5)(14)=5g+70
The expressions aren't equal as 5(g+14) equates to 5g+70 and 5g+70≠5g+14.

The school bus has 18 rows of seats. There are 4 students in each row. Each student has 3 books to bring home. How many students are on the bus?
Answer:
Step-by-step explanation:
*The part about how many books per student is irrelevant to the question*
All you need to do is multiply 18 rows by 4 students per row.
18 * 4 = 72 total students on bus
Answer:
72
Step-by-step explanation:
18 times 4 equals 72. If there are 4 students in EACH row out of all the 18, then there is 72 kids on the bus.

Find the measure of angle 3=
Answer: 50°
Step-by-step explanation:
Since angle 3 is in a right triangle we can assume one angle is 90° and then the other missing angle will be 40°
Because you take 180°-140°(the angle next to it) which will equal 40°
Now every triangle must add up to 180°
so lets take the angles we have now
90° +40°=130°
now take that 130°
180°-130°=50°
Now check your work
90°+40°+50°=180°
Angle 3 is 50°
The Westbrook Pharmaceutical Company manufactures atorvastatin pills, designed to lower cholesterol levels. Listed below are the amounts (in mg) of atorvastatin in a random sample of the pills. Use a 0.05 significance level to test the claim that the pills come from a population in which the amount of atorvastatin is equal to 25mg.
24.1, 24.4, 24.3, 24.9, 24.1, 26.2, 25.1, 24.7, 24.4, 25.0, 24.7, 25.1, 25.3, 25.5, 25.5
Solution :
Given :
[tex]$\mu = 24$[/tex]
n = 15
[tex]$\overline x = 24.89$[/tex]
s = 0.5902
The hypothesis :
[tex]$H_0 : \mu = 25$[/tex]
[tex]$H_a : \mu \neq 25$[/tex]
This is a 2 tailed test.
The significance level is [tex]$95 \% \ ( \alpha =0.05)$[/tex]
The test statistic :
[tex]$Z=\frac{\overline x - \mu}{\frac{\sigma}{\sqrt n}}$[/tex]
[tex]$Z=\frac{24.89-25}{\frac{0.5902}{\sqrt 15}}$[/tex]
= -0.72
The p value : The p value for Z = -0.72 is 0.4716
The critical value : the critical value at α = 0.05 is +1.96 to -1.96
The decision rule :
If [tex]$Z_{observed} > Z_{critical}$[/tex] or if [tex]$Z_{observed} < -Z_{critical}$[/tex], then reject [tex]$H_0$[/tex].
Also if p value is less than α, then reject [tex]$H_0$[/tex].
The decision :
Since the Z falls in between +1.96 and -1.96, we fail to reject the [tex]$H_0$[/tex]. Also since p value is greater than α, we fail to reject [tex]$H_0$[/tex].
The conclusion :
There is not sufficient evidence at the 95% significance level to warrant rejection of the claim that the pills come from a population in which the amount of the atorvastatin is equal to 25 mg.
Now calculating the mean and the standard deviation :
[tex]$\text{Mean} = \frac{\text{sum of observation}}{\text{total observations}}$[/tex]
Standard deviation = [tex]$\sqrt{\text{variance}}$[/tex]
Variance = [tex]$\frac{\text{sum of squares(SS)}}{n-1}$[/tex]
Where, SS = [tex]$\sum (X - \text{mean})^2$[/tex]
X Mean [tex]$(X-\text{mean})^2$[/tex]

Step-by-step explanation:
find the measure of angle A
Answer:
30
Step-by-step explanation:
Right angle = 90 degrees
180-90 = 90, hence the right side of the equation.
x+37+x+67 = 90
2x + 104 = 90
2x = -14
x = -7
Plug in x.
-7+37 = 30 (angle a)
Angle a = 30
Answer:
angle A = 30 degrees
Step-by-step explanation:
*All triangles have an interior angle that adds up to 180 degrees
The triangle is the picture is a right triangle so one of the angles is 90 degrees.
First, we must figure out what "x" is:
⇒ 180 = 90 + x + 37 + x + 67
Combine like terms:
⇒ 180 = 2x + 194
Subtract 231 from both sides:
⇒ 180 - 194 = 2x + 149- 194
⇒ -14 = 2x
The divide both sides by 2:
⇒ [tex]\frac{-14}{2} + \frac{2x}{2}[/tex]
⇒ -7 = x
Now, we can figure out what angle A is by taking the equation "x + 37" and subtituting x by -7:
⇒ x + 37
⇒ -7 + 37
⇒ 30
To check out answers, take all of the eqautions in the picture and subtitute x by -7, (remember that it must add up to 180):
⇒ 90 + x + 37 + x + 67 = 180
⇒ 90 + (-7) + 37 + (-7) + 67 = 180
⇒ 180 = 180
I need help on both, I don’t understand. It’s dealing with similar triangles
Answer:
11. MN = 4 m
12. LK = 8 m
Step-by-step explanation:
11. Apply pythagorean theorem to find MN:
MN = √(5² - 3²) = √(25 - 9) = √16
MN = 4 m
12. Recall: The ratio of the corresponding side lengths of any two given similar triangles are equal.
MN corresponds to LK
MO corresponds to KO
Therefore:
LK/MN = KO/MO
LK/4 = 10/5
LK/4 = 2
Multiply both sides by 4
LK = 2*4
LK = 8 m

a. 40
b. 46.3
c. 20.5
d. 23.7
Answer:
23.7°
Step-by-step explanation:
To obtain the value of AB ; Use the cosine rule ;
Recall:
c² = a² + b² - 2ab Cos C
c² = 24² + 11² - 2*24*11 Cos75
c² = 576 + 121 - 528 * 0.2588190
c² = 697 - 136.656432
c² = 560.343568
c = sqrt(560.343568)
c = 23.6715
Hence, c = AB = 23.7°
