4. If the expression 25y^2- 70y+d is a perfect square, where d is a constant, find the
value of d.
Answer:
d = 49
Step-by-step explanation:
Given that the expression is a perfect square of the form
(ay - b)² = a²y² - 2aby + b²
Then comparing like terms
a²y² = 25y², that is
a² = 25 ⇒ a = 5
and -2aby = - 70y, thus
2ab = 70, that is
2(5)b = 70
10b = 70 ⇒ b = 7
b² = 7² = 49
Hence
25y² - 70y + d = (5y - 7)² = 25y² - 70y + 49
Thus d = 49

Car color is not red or blue.
options:
0.51
0.47
0.53
0.49
Answer:
P(The color of the car is red) is 0.32 .
P(The color of the car is white) is 0.34 .
P(The color of the car is silver) is 0.19 .
P(The color of the car is blue) is 0.15 .
P(car color is not red or blue) is 0.53 .
Step-by-step explanation:
We know that total angle subtended at the center by a complete circle is
360° .
According to the question,
P(The color of the car is red)
= [tex]\frac {115.2}{360}[/tex]
= 0.32
P(The color of the car is white)
= [tex]\frac {122.4}{360}[/tex]
= 0.34
P(The color of the car is silver)
= [tex]\frac {68.4}{360}[/tex]
= 0.19
P(The color of the car is blue)
= [tex]\frac {54}{360}[/tex]
= 0.15
So
P(car color is not red or blue)
= 1 - (0.15 + 0.32)
= 0.53

One number is 7 less than a second number. Twice the second number is 1 less than 5 times the first. Find the two numbers.
One number is 7 less than a second number. Twice the second number is 1 less than 5 times the first. Then the two numbers are 5 and 7
Solution:
Given that one number is 7 less than a second number.
Twice the second number is 1 less than 5 times the first.
Need to determine two numbers.
Let assume first number be represented by variable x and second number be represented by variable y.
As first number is 7 less than a second number, adding 7 to first number will give us second number
=> x + 7 = y ------ (1)
[tex]\begin{array}{l}{\text { Twice of second number }=2 \times \text { second number }=2 \times y=2 y} \\\\ {\text { 5 times the first number }=5 \times \text { first number }=5 \times x=5 x}\end{array}[/tex]
As given that Twice the second number is 1 less than 5 times the first , if we 1 to twice of second number we will get 5 times first number ,
=> 2y + 1 = 5x ------ (2)
On substituting value of y as x + 7 from equation 1 into equation 2 , we get
2(x + 7) + 1 = 5x
=> 2x + 14 + 1 = 5x
=> 2x – 5x = -15
=> -3x = -15
x = 5
Substituting x = 5 in equation (1) to get value of y
=> y = 5 + 7 = 12
Hence first number is 5 and second number is 12
If on a scale drawing 75 feet are represented by 45 inches, then a scale of 1/5 inch represents how many feet?
Answer:
1/3 or 0.33 feet
Step-by-step explanation:
This question can be easily answered by using simple proportions.
If 75 feet are represented by 45 inches on a scale, then the scaling factor from feet to inches is 45/75, or from inches to feet is 75/45
If we have 1/5 inch and want feet, just multiply by 75/45 to get
1/5*75/45=1/3=0.33 feet
Answer:
1/3 feet
Step-by-step explanation:
We are given that
On a scale drawing
45 inches represented =75 feet

Using unitary method
45 inches represents =75 feet
1 inch represents =[tex]\frac{75}{45}[/tex] feet
1/5 inch represents =[tex]\frac{75}{45}\times \frac{1}{5}[/tex] feet
1/5 inch represents=[tex]\frac{1}{3}[/tex] feet
Hence, a scale of 1/5 inch represents 1/3 feet

the answer is 9:10 hope it helps
Final answer:
Katie was a quarter of an hour, or 15 minutes, late to school which starts at 8:55 AM. So, she arrived at 9:10 AM.
Explanation:
If school starts at 8:55 AM and Katie was a quarter of an hour late, that means she was 15 minutes late because a quarter of an hour is 15 minutes (60 minutes divided by 4 equals 15 minutes).
To find out what time Katie arrived, we need to add 15 minutes to the starting time of school:
School starts: 8:55 AM
Time late: + 15 minutes
Time of arrival: 9:10 AM
So, Katie arrived at school at 9:10 AM.

There are 4, 000 books in the towns library. Of these, 2, 600 are fiction. Write a percent equation that you can use to find the percent of the books that are fiction. Then solve your equation.
The percent equation showing the fiction books is y = 0.65x showing that among the 4,000 books in the library, 2,600 are fiction.
An equation is a mathematical representation of the equality of two expressions.
The number of books in the town's library = 4,000
The number of fiction books = 2,600
The number of nonfiction books = 1,400 (4,000 - 2,600)
The percentage of fiction books to the total number of books = 65% (2,600/4,000 x 100)
Let the total number of books in the library = x
Let the number of fiction books = y
Equation:
y = 0.65x
y = 2,600 (0.65 x 4,000)

The perimeter of a basketball court is 90 meters and the length is 6 meters longer than twice the width. What are the length and width?
The length of basketball court is 32 meters and width is 13 meters.
Step-by-step explanation:
Perimeter = 90 meters
Let w be the width
Length = l = 2w + 6
As basketball court are in rectangular shapes, therefore,
Perimeter = 2(length+width)
[tex]90=2(2w+6+w)\\90=2(3w+6)\\90=6w+12\\90-12=6w\\6w=78[/tex]
Dividing both sides by 6;
[tex]\frac{6w}{6}=\frac{78}{6}\\w=13\ meters[/tex]
Length = 2w+6
[tex]l=2(13)+6\\l=26+6\\l=32\ meters[/tex]
The length of basketball court is 32 meters and width is 13 meters.
