Time that will be taken at speed of 45 miles/hr is 1.8 hrs
Step-by-step explanation:
Step 1: Given the speed of the journey = 54 miles/hr and time = 1.5 hours. Find the distance of the journey using the speed formula.Distance = Speed × Time
= 54 × 1.5 = 81 miles
Step 2: Calculate the time taken for this journey given speed = 45 miles/hrTIme = Distance/Speed
= 81/45 = 1.8 hrs

Ivanna is a software saleswoman. Let y represent her total pay (in dollars). Let x represent the number of copies of History is Fun she sells. Suppose that x and
y are related by the equation 2400+120x = y.
Answer the questions below.
Note that a change can be an increase or a decrease.
For an increase, use a positive number. For a decrease, use a negative number.
What is the change in Ivanna's total pay for each copy of History is Fun she sells?
$
What is Ivanna's total pay if she doesn't sell any copies of History is Fun?
1. For every extra copy, Ivanna sells she gets an additional 120 dollars (+$120) and for every less copy she loses $120 dollars (-$120).
2. Ivanna's total pay is $2,400 if she doesn't sell any copies of History is Fun.
Step-by-step explanation:
Step 1:
y = 2,400 + 120x, where y is Ivanna's total pay and x is the number of copies of history is fun she sells.
To calculate the change is Ivanna's pay we find the difference in pay for two consecutive values of y.
We must calculate y when x is of consecutive values i.e. 1, 2, 3, 4 ...
Step 2:
We calculate the value of y when x = 1, 2 and 3.
When x = 1, y = 2,400 + 120 (1) = 2,400 + 120 = $2,520.
When x = 2, y = 2,400 + 120 (2) = 2,400 + 240 = $2,640.
When x = 3, y = 2,400 + 120 (3) = 2,400 + 360 = $2,760.
Step 3:
To calculate the increase in her pay for a copy, we subtract y when x = 2 from y when x = 3.
(y when x = 3) - (y when x = 2) = $2,760 - $2,640 = $120.
So for every extra copy, Ivanna gets an extra $120.
To calculate the decrease in her pay for a copy, we subtract y when x = 3 from y when x = 2.
(y when x = 2) - (y when x = 3) = $2,640 - $2,760 = -$120.
So for every less copy, Ivanna loses $120.
Step 4:
To calculate her pay when she doesn't sell any copies of history is fun, we substitute the value of x as 0 in y.
When x = 0, y = 2,400 + 120 (0) = $2,400.
So Ivanna earns $2,400 if she doesn't sell any copies of history is fun.
9.0758 to 2 significant figures.
Answer w/ explanation:
The answer is 9.1
To round to 2 significant figures, we have to find the first significant figure. We find the first sig fig by looking for the first nonzero digit in the number (it can be before or after the decimal point), which is "9"
The next digit is "0". This will also be a significant figure in our answer.
It may seem we are done now since we found the two significant figures. However, let's look at the digit after "0" to see if we need to round up or down.
The digit after "0" is "7". Since 7 is greater than 5, we round up the "0" to a "1" in our final answer, making the answer 9.1
Side note:
The definition and concept of significant figures can be very confusing overall, so please continue to ask questions if you are still struggling with them.

between the time Iko woke up and lunchtime, the temperature rose by 11°. Then by the time he went to bed, the temperature dropped by 14 °. Write an addition expression for the temperature relative to when Iko woke up.
Answer:
x + (11) + (-14) [x being temperature when Iko woke up]
Step-by-step explanation:
Let the temperature be "x" when Iko woke up
Then,
Temperature ROSE 11° in lunch
The temp in lunch was: x + 11
Then the temperature DROPPED 14° when he went to bed, relative to lunch temperature, so we can say:
(x + 11) - 14
So, the final temperature that end of day was:
x + 11 - 14
As addition expression, it will be:
x + (11) + (-14)

There are 27 girls and 36 boys who want to participate in a math competition. If each team must have the same ratio of girls and boys what’s the greatest number of teams that can enter?
Since the ratio of girls and boys must be the same in each team, and all the competitors must be involved, it means that each team's ratio of boys : girls must be equal to the total ratio of Boys : Girls = 36 :27= 4 / 3.
Now 4 / 3, the most simplified version of 36 / 27, happens by dividing the numerator & demoninator by 9 (the greatest number it can divide by). So the greatest number will be 9 teams, each of 4 Boys & 3 Girls

1. Find the x-intercept of the line: 5x - y = 10
2. Find the y-intercept of the line: 9x + 3y = -18
3. What are the x- and y- intercepts of the graph of 6x - 4y = -12
Final answer:
The x-intercept of the line 5x - y = 10 is (2, 0), the y-intercept of the line 9x + 3y = -18 is (0, -6), and the equation 6x - 4y = -12 has an x-intercept at (-2, 0) and a y-intercept at (0, 3).
Explanation:
To find the x-intercept of a line, we set the value of y to zero and solve for x. For the equation 5x - y = 10, we set y to 0:
5x - (0) = 10
5x = 10
x = 2
The x-intercept is therefore the point (2, 0).
To find the y-intercept of a line, we set the value of x to zero and solve for y. For the equation 9x + 3y = -18, we set x to 0:
(0) + 3y = -18
3y = -18
y = -6
The y-intercept is therefore the point (0, -6).
For the equation 6x - 4y = -12, the x-intercept and y-intercept can be found similarly. Let's start with the x-intercept. Set y to 0:
6x - (0) = -12
6x = -12
x = -2
The x-intercept is the point (-2, 0). Now, for the y-intercept, we set x to 0:
(0) - 4y = -12
-4y = -12
y = 3
The y-intercept is the point (0, 3). Thus, for 6x - 4y = -12, the intercepts are x = -2 and y = 3.

What is the angle of a triangle if one angle is 68 and the other is 52
Answer:
The last angle is 60 degrees
Step-by-step explanation:
All triangles add up to 180 degrees
Step 1: Make an equation
What is the angle of a triangle if one angle is 68 and the other is 52.
68 + 52 + x = 180
Step 2: Combine like terms
68 + 52 + x = 180
120 + x = 180
Step 3: Subtract 120 from both sides
120 + x - 120 = 180 - 120
x = 60
Answer: The last angle is 60 degrees
The sum of the angles in a triangle will be equal to 180°.
68 + 52 = 120°
180 - 120 = 60° (This is the 3rd angle)

The circumference of a circular frisbee is 20 centimeters. If
we multiply the radius of the frisbee by 5, what will be the
circumference of the new frisbee?
OA) 981 cm
OB) 100 cm
OC) 1451 cm
OD 2007 cm
Answer:
100cm
Step-by-step explanation:
since the circumference is 20cm and formula for finding a circumference of a circle is c=2(pi)r, where r is radius and pi is constant value which is equivalent to 22/7. so the radius of 20cm circumference is 3.1847 by using this eqn c/2(pi)=r. now the calculated radius will b multiply by 5 to get 15.92cm which is put in cirumference formula i.e. c=2(pi)r we get 100cm circumference.
