This equation shows how the time required to complete an online shopping transaction is related to the number of products being purchased. t = 24p + 27 The variable p represents the number of products, and the variable t represents the time required to complete the transaction. If it takes 51 seconds to complete a transaction, how many products are being purchased?
Answer:
1 product
Step-by-step explanation:
Given the equation that shows how the time required to complete an online shopping transaction is related to the number of products being purchased as;
t = 24p + 27
t represents the time required to complete the transaction
p is the product purchased
If it takes 51 seconds to complete a transaction, to get the amount of product purchased, we will substitute t = 51 into the expression and find p as shown;
51 = 24p + 27
Substract 27 from both sides
51-27 = 24p + 27 - 27
24 = 24p
24p= 24
p = 24/24
p = 1
Hence only 1 product is being purchased

1. The diagonal of a quadrilateral
is of length 8.5 m and the lengths
of the perpendiculars dropped on
it from the remaining opposite
vertices are 3.5 cm and 4.5 cm.
Find the area of the quadrilateral.
Consider the length of diagonal is 8.5 cm instead of 8.5 m because length of perpendiculars are in cm.
Given:
Length of the diagonal of a quadrilateral = 8.5 cm
Lengths of the perpendiculars dropped on it from the remaining opposite vertices are 3.5 cm and 4.5 cm.
To find:
The area of the quadrilateral.
Solution:
Diagonal divides the quadrilateral in 2 triangles. If diagonal is the base of both triangles then the lengths of the perpendiculars dropped on it from the remaining opposite vertices are heights of those triangles.
According to the question,
Triangle 1 : Base = 8.5 cm and Height = 3.5 cm
Triangle 2 : Base = 8.5 cm and Height = 4.5 cm
Area of a triangle is
[tex]Area=\dfrac{1}{2}\times base \times height[/tex]
Using this formula, we get
[tex]Area(\Delta 1)=\dfrac{1}{2}\times 8.5\times 3.5[/tex]
[tex]Area(\Delta 1)=14.875[/tex]
and
[tex]Area(\Delta 2)=\dfrac{1}{2}\times 8.5\times 4.5[/tex]
[tex]Area(\Delta 2)=19.125[/tex]
Now, area of the quadrilateral is
[tex]Area=Area(\Delta 1)+Area(\Delta 2)[/tex]
[tex]Area=14.875+19.125[/tex]
[tex]Area=34[/tex]
Therefore, the area of the quadrilateral is 34 cm².

Mr. Swanson needs new strings for his 19 violin students. Each violin has 4 strings. Strings are $2 each and come in sets of 4. Mr. Swanson decides to buy 2 sets of strings for each student.
a school year has 4 quarters.what percent of the school year is 7 quarters?
Answer:
175%
Step-by-step explanation:
You "have" 7/4 quarters, which, when you divide 7 by 4, gives you 1.75.
This is only a ratio (1.75 out of 1 whole), so to get it into percentage you need to multiply 1.75 by 100, giving you 175 percent.
Which expression is equivalent to 20y2+5y? A) 5y(4y+1) B) −5y(4y−1) C) −5y(4y+1) D) 5y(4y−1)
Answer:
A
Step-by-step explanation:
I want to believe the question is
20y² + 5y
If so, then the answer is A. If we apply factorisation method to the question. We first start by finding the greatest common factor, and in this expression, the greatest common factor is 5y. So we write that down outside the bracket. Next, we divide 20y² by 5y and also 5y by 5y to give us 4y and 1. Thus, the answer is
5y(4y + 1).
This can be crops checked by opening the brackets once again.

Answer:
Q1.
x = 83°
y = 79°
Q2.
x = 36°
y = 108°
Step-by-step explanation:
Q1.
Since, measure of exterior angle is equal to the measure of interior opposite angle.
Therefore,
x = 83°
y = 79°
Q2.
Since, y is the measure of exterior angle of the isosceles triangle, hence, by exterior theorem:
y = 54° + 54°
y = 108°
Since, x is the measure of the interior angle of the isosceles triangle.
Thus, by interior angle sum postulate of a triangle:
x + x + y = 180°
2x + 108° = 180°
2x = 180° - 108°
2x = 72°
x = 72°/2
x = 36°

How does the distributive property relate to factoring expressions?
Answer:
i'm truly sorry for answering very late. here's your answer-
a factor is a number that can be divided into another number evenly. for example, the factors of 6 are 1, 2, 3, and 6.. it means that a number outside the parentheses of an addition problem can be multiplied by each number inside the parentheses. hope this helps<3
i wish you the best of luck :)
Answer:
2021... oop.
you can use factoring to create equivalent expressions
Step-by-step explanation:
To factor an expression, we use the distributive property to rewrite a sum as a product. The new expression is equivalent to the original expression. For example, we can factor the expression 20x+35 to get the equivalent expression 5(4x+7).

9-8w + 7w = 3(w+1) how to solve
Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Hey there
Steps to solve this problem :
9-8w + 7w = 3(w+1)
Add simlar elements : -8+7=-w
9-w=3w+3
Subract 9 from both sides:
9-w-9 = 3w + 3 - 9
simplfy :
-w = 3w - 6
subract 3w from both sides :
-w - 3w = 3w - 6 - 3w
simplfy :
- 4w = -6
divide both sides by -4:
[tex]\frac{-4w}{-4} = \frac{-6}{-4}[/tex]
simplify :
w = [tex]\frac{3}{2}[/tex]
Have a wonderful day
Answer:
w= 3/2 = 1.5
Step-by-step explanation:
9-8w + 7w = 3(w+1)
First do the distribution 3(w+1) = 3w +3
9-8w + 7w = 3w+3
9-w= 3w+3
9 = 4w +3
6= 4w
divide both sides by 4
w= 6/4 (simplify to 3/2)= (1.5)
8w =12
7w= 10.5
3w=4.5
Work out the percentage change to 2 decimal places when a price of £125.99 is increased to £150.
Answer:
Percent change is 19.06%
Step-by-step explanation:
It is given that:
Price before change = £125.99
Price after increase = £150
Change = 150 - 125.99 = £24.01
Percent of change = [tex]\frac{Change}{Price\ before\ change}*100[/tex]
Percent of change = [tex]\frac{24.01}{125.99} * 100[/tex]
Percent of change = 0.1906 * 100
Percent of change = 19.06%
Therefore,
Percent change is 19.06%
Answer:
19.06
