Answer:
$12 is the sale price of shirt.
Explanation:
Calculate the percentage of sale
[tex]\sf \rightarrow \sf \dfrac{15}{20} *100[/tex]
[tex]\sf \rightarrow \sf 75 \%[/tex]
Then find the sale price of shirt
original price * percentage of sale
$16 * 75%
$12
Answer:
$12
Step-by-step explanation:
Method 1First, calculate the sale discount as a percentage using the given information about the pants.
$20 = Original price of pants$15 = Sale price of pants[tex]\sf percent\:change=\dfrac{|final\:value-initial\:value|}{initial\:value} \times 100[/tex]
[tex]\implies \sf percent\:change=\dfrac{|15-20|}{20} \times 100=25\%[/tex]
Therefore, the clothes are on sale with a 25% discount.
This means they are 75% of the original sale price, as 100% - 25% = 75%
To find the sale price of the shirt, we simply need to find 75% of the original selling price of the shirt:
75% of $16
= 0.75 × $16
= $12
Method 2Using ratios of original price : sale price, where x is the sale price of the shirt:
pants → 20 : 15
shirt → 16 : x
Therefore, as the ratios are the same:
20 : 15 = 16 : x
⇒ 20/15 = 16/x
⇒ 20x = 16 · 15
⇒ 20x = 240
⇒ x = 240 ÷ 20
⇒ x = 12

tan2x=___
A. tan x/1+tan^2 x
B. tan x/1-tan^2 x
C. 2tan x/1-tan^2 x
D. 2tan x/1+tan^2 x
Step-by-step explanation:
tan2x = sin2x/cos2x
we know that ,
sin2x = 2sinxcosx sin2x = 2sinxcosx cos2x = cos²x - sin²xSince, tan2x = 2sinx*cosx/cos²x- sin²x
Dividing by cos²x in numerator and denominator.
We get ,
tan2x = 2sinx/cosx / 1- sin²x/cos²x Since, we get tan2x= 2tanx/1-tan²x Option (c) is correct option. Hope it will be helpfulThe length of a Ping Pong table is 3 ft less that four times the width. The area of the

what’s the answer to this problem , figure out the area and perimeter of this triangle
Answer:
Area: 16.65m^2 (^2 means to the power of 2 exponent, or squared)
Perimeter: 26.3 m
Step-by-step explanation:
Triangle Area formula: bh/2
Plug it in: (7.4)(4.5)/2=16.65
Perimeter: Add the sides
12.6+7.4+6.3=26.3
Answer:
Step-by-step explanation:
Remark
Here are the formulas for what you are asking for.
P = s1 + s2 + s3
Area = height * base / 2
Givens
s1 = 12.6
s2 = 6.3
s3 = 7.4
height = 4.5
base = 7.4
The area is just slightly different than it normally is. The reason is the height. It is not directly connected to the base. The construction is called the base extended. See the givens for what that is.
Solution
Perimeter
P = s1 + s2 + s3 Substitute givens into the formula
P = 12.6+6.3 + 7.4
p = 26.3
Area
Area = (B * H)/ 2
Area = 7.4 *4.5 / 2
Area = 16.65
Answer my practice question. Today, the sum of Cameron's age and Christian's age is 102. 6 years ago Christian was 2 times older than Cameron.
Part A: Enter Cameron's age today.
Part B: Enter Christian's age today
Answer:
Cameron's age=48 Christain's age=54
Step-by-step explanation:
The current total age is 102.
You can do 102-6 as this will give you an idea of Christain's age as it is twice the age of Cameron.
102-6=96
96/2=48
Cameron's age=48
102-48=54
54=Christain's age
Given the value of the hypotenuse c for a 45°-45°-90° triangle, write the
equations to represent sides a and b in terms of c.
a= c/√2
b= c/√2
Since side a and b are equivalent to each other and c is the length of side a or b × √2. Dividing c by √2 gives the value of a and b.
a×√2= c
b×√2= c

Pauline’s Pie’s baked 150 pies before they opened the store on Sunday. Once the store opened, they sold 30% of the pies before noon. How many pies were sold before noon?
Answer:
105
Step-by-step explanation:
First, in problems like these, you have to find 30% of 150. 30% of 150 is 45. Now, since you want to see how many pies have been sold, you do 150-45, which will give you 105.

a customer is more likely to have 1 pet and no children than they are to have
A customer is more likely to have 1 pet and no children than they are to have 2 pets and no children.
How to find probability?
We are given a table with 3 columns titled "have children", "do not have children" and "total".
Under the row titled "1 pet", the respective probabilities are;
P(having 1 pet and children) = 38/91 = 0.4176
P(having 1 pet and no children) = 53/91 = 0.5824
Under the row titled "2 pets", the respective probabilities are;
P(having 2 pets and children) = 85/126 = 0.6746
P(having 2 pets and no children) = 41/126 = 0.3254
Under the row titled "3 or more pets", the respective probabilities are;
P(having 3 or more pets and children) = 46/118 = 0.3898
P(having 3 or more pets and no children) = 72/118 = 0.6102
The only probability that is lower than P(having 1 pet and no children) in the same way is P(having 2 pets and no children).

Answer:
Part A: f(4) = 2
Part B: k = -7
Step-by-step explanation:
f(4) simply means what the y-value of the graph is when x = 4.
The parabola crosses the coordinate (4,2). In other words, when x = 4, the graph equals 2.
Part B asks to solve the equation: f(4) + k = -5
We already know from Part A that f(4) = 2. So simply substitute 2 for f(4):
2 + k = - 5
Substract 2 from both sides:
k = -7
Stacy recorded the number of minutes she used her

How to find the value of z-statistic for population mean? (z test statistic)Suppose we're specified that:
The sample mean = [tex]\overline{x}[/tex]
The population mean =[tex]\mu[/tex]
The population standard deviation = [tex]\sigma[/tex]
The sample size = n
Then the z-statistic for this data is found as:
[tex]Z = \dfrac{\overline{x} - \mu}{\sigma/\sqrt{n}}[/tex]
In this problem, the values of those parameters are as follows:
The sample mean [tex]\overline{x}[/tex] = -0.2
The population mean =[tex]\mu[/tex] = 0
The population standard deviation = [tex]\sigma[/tex] = 9.1
The sample size = n = 200
Hence, the test statistic is given by:
[tex]Z = \dfrac{\overline{x} - \mu}{\sigma/\sqrt{n}}\\\\\\Z = \dfrac{-0.2- 0}{9.1/\sqrt{200}}\\\\z = 0.31[/tex]
Thus,
t = 0.31.
Since the absolute value of the test statistic is less than the critical value, we do not reject the null hypothesis and the conclusion is:
Phone use did not change.

what’s the answer to this problem , figure out the area and perimeter of this triangle
Answer:
Area=16.65
Perimeter=26.3
Step-by-step explanation:
To find the area of a triangle, you must multply the length and height and divide by two. An equation like this could help find the area of a triangle: A=2÷(L×W) In your case, 7.4 is the length and 4.5 is the base. Multiply 7.4 and 4.5 together and divide the result by 2.
To find the perimeter, just add 7.4, 6.3, and 12.6 together. 4.5 doesn't get added, only the 3 sides of the triangle do. Don't forget to label the measurements.
