Answer:
9:45 AM
Step-by-step explanation:
To get to work in the morning, Amanda cycles for 10 miles at the rate of 12 mph.
Time (hours) = Distance/speed
Hence, the time she spends cycling = 10mile/12 mph
= 0.8333333333 hour
Converting to minutes:
1 hour = 60 minutes
0.8333333333 hour =
0.8333333333 hours × 60 minutes/1 hour
= 50 minutes.
Hence, she spends 50 minutes cycling
She makes a 10 minutes stop for a cup of coffee, and then rides a bus for 15 minutes. The speed of the bus is 45 mph.
The total number of minutes she spends to get to work is calculated as:
(50 + 10 + 15)minutes
= 75 minutes.
It takes Amanda 75 minutes to get to work.
At what time will Amanda get to work if she leaves home at 8:30 AM?
= 8:30AM + 75 minutes
= 8:30 AM + 1 hour 15 minutes
= 9:45 AM
x+(x+4)=28 ?
What does x equal?
Answer:
x=12
Good Luck!!!
The correct answer is x=12
-x-y=11
convert from standard form to slope intercept form
Answer:
y = - x - 11
Step-by-step explanation:
-x-y=11
+x +x
-y=11+x
/- /-
y=-11-x
rearrange
y = - x - 11
Answer:
y =-x-11Step-by-step explanation:
Slope intercept form : y=mx+b
[tex]-x-y=11\\\\-y =x +11[/tex]
Multiply by -1(reverse the inequality)
[tex]-1(-y=x+11)\\\\y =-x-11[/tex]
8. The graph below represents the path of a golf ball.
The Path of a Golf Ball
Part A: The above graph is (circle one) linear/nonlinear.
Part B: Is the above graph a function? Explain.
Part C: What is the y-intercept and what does the y-intercept
representa
Part D: What is the solution to this graph and what does it represent in this
situation?
Answer:
Part A: Non linear
Part B: Yes
Part C: The y-intercept is (0, 0), represent the starting height level of the golf ball
Part C: The solution are the points (0, 0) and (100, 0) which are the points at which the golf ball touches the ground
Step-by-step explanation:
Part A: The shape of the path of the increase in the height of the the golf ball as it moves in increasing horizontal distance from the starting point is hat of a parabola
Part B: The graph is a function because each value of the independent variable, distance (ft.) maps to exactly one value of the dependent variable, elevation (ft.)
Part C: The y-intercept represents the starting or initial value of the function, where x = 0. It represents the height from which the golf ball motion path starts
Part D: The solution represents the values of the x-intercept at which the elevation is the y = 0.
If f(x) = 2x - 4, find f(3)
Answer:
f(3) = 2
Step-by-step explanation:
f(x) = 2x - 4 when f(3). In other words substitute x with 3 to solve.
f(3) = 2(3) - 4
f(3) = 6 - 4
f(3) = 2

Hugh made a recipe that yields 5 and 1 over 4 cups. If each serving is 1 over 2 cup, which expression will help Hugh determine the number of servings his recipe will yield?
Answer:
10 1/2 servings
Step-by-step explanation:
Hugh made a recipe that yields 5 and 1 over 4 cups.
Recipe = 5 1/4 cups = 21/4 cups
1 serving = 1/2 cup
The number of serving that Hugh's recipe would generate =
1/2 cup =>1 serving
21/4 cups => x
Cross Multiply
x = 21/4 / 1/2
= 21/4 ÷ 1/2
= 21/4 × 2/1
= 21/2
= 10 1/2 servings
The number of servings his recipe will yield is 10 1/2 servings

9. Large postcards come in packages of 20. Small postcards come in packages of 25. A store buys 24 packages of large postcards and 18 packages of small postcards. Which statement is true? * 10 points The store bought a total of 930 postcards The store bought 30 more small postcards than large postcards The store bought a total of 932 postcards. The store bought 68 more large postcards than small postcards.
Answer: 930 packages.
Step-by-step explanation:
Large postcards come in packages of 20.
Small postcards come in packages of 25.
A store buys 24 packages of large postcards. The total packages will then be:
= 20 × 24 = 480
The store buys 18 packages of small postcards. The total package here will be:
= 18 × 25 = 450
Therefore, total packages bought will be:
= 480 + 450
= 930 packages
Answer:
Step-by-step explanatill postcards than large postcards The store bought a total of 932 postcards. The store bought 68 more large postcards than small postcards
package A weighs 5 1/2 pounds and package B weights 1 1/4 pounds. find the average weight of the two packages
Answer:

Step-by-step explanation:
add both weights together, then divide by two since there are two factors. (5.5 + 1.25)/2 is 3.375 pounds
what is the slope of the line that passes through the points (-7,-7) and (-7.1)
Answer:
Undefined
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the two points:
(y2 - y1) / (x2 - x1)
(1 + 7) / (-7 + 7)
8/0
= undefined
So, the slope is undefined, since you cannot divide by zero.
The slope of the lines that passes through the points (-7,-7) and (-7.1) is an infinite slope.
Slope equation:The slope formula is described as follows:
m = y₂ - y₁ / x₂ - x₁Therefore,
x₁ = -7
x₂ = -7
y₁ = -7
y₂ = 1
m = 1 - (-7) / -7 - (-7)
m = 1 + 7 / -7 + 7
m = 8 / 0
m = infinity
The slope is an infinite slope. Therefore, it is a vertical line.

Find the zeroes of the quadratic polynomial given below. find the sum and products of the zeroes and verify relationship of terms in the polynomial.
2. P of x = x square _4x+3
• P(x) = x² - 4x +3
To find :• The zeroes of the quadratic polynomial .
• To verify the relationship .
Solution :•x² - 4x + 3 = 0
Split the middle term :
=> x² - 3x - x + 3 = 0
=> x ( x - 3) - 1 ( x - 3 ) = 0
=> (x - 1)( x - 3 ) = 0
• x - 1 = 0
=> x = 1 .
• x - 3 = 0
=> x = 3 .
Hence , the zeroes are 1 and 3 .
Now , verification :• x² - 4x +3 .
compare with ax² + bx + c we get ,
• a = 1 , b = -4 and c = 3 .
As we know that :
• Sum of Zeroes = -b/a
=> 1 + 3 = -(-4)/1
=> 4 = 4
LHS = RHS .
NOW ,
• Product of Zeroes = c/a
=> 1(3)= 3/1
=> 3 = 3
LHS = RHS .
Hence, Verified .

Ben exercises every 12 days and Isabel every 8 days. Ben and Isabel both exercised today. How many days will it be until they exercise on the same day again?
Answer:
24 days
Step-by-step explanation:
First, we need to determine the Lowest common multiplier(LCM) of both days.
Given that;
Ben exercise for 12 days ,
Isabel exercise for 8 days
Hence, the LCM of both days is
12 = 2 × 2 × 3
8 = 2 × 2 × 2
Therefore,
LCM = 2 × 2 × 2 × 3 = 24.
It will take both Ben and Isabel 24 days to exercise on the same day again

what is 0.98989898 with bar notation
Answer:
the answer would be .735
Step-by-step explanation:
Answer:
[tex]\frac{98}{99}[/tex]
Step-by-step explanation:
We require to create 2 equations with the repeating value (0.989898... )
placed after the decimal point.
let x = 0.989898.... → (1) ( multiply both sides by 100 )
100x = 98.9898..... → (2)
Subtract (1) from (2) thus eliminating the repeating decimal
99x = 98 ( divide both sides by 99 )
x = [tex]\frac{98}{99}[/tex]
Thus
0.989898... = [tex]\frac{98}{99}[/tex] as an exact fraction
Terry is paid $6.05 for evrey box of fruit picked and a bonus of $26.89 if more than 18 boxes are packed in one day. How much does Terry earn if he picks 49 boxes of fruit in one day
Answer:
The total amount earned by Terry is $323.34
Step-by-step explanation:
amount paid to Terry for every box of fruit picked, A = $6.05
bonus of $26.89 when more than 18 boxes are picked.
Amount earned by Terry for picking 49 boxes is given by;
A = $6.05 x 49 = $296.45
bonus earned by Terry since he picked more than 18 boxes in a day = $26.89
The total amount earned by Terry is given by;
Total amount = $296.45 + $26.89
Total amount = $323.34
Therefore, the total amount earned by Terry is $323.34
