Caroline bakes cookies in batches of 24. If she bakes 3 batches of cookies per week, how many weeks would it take her to bake 2,088 cookies?
Answers
Answer: 29 weeks
Step-by-step explanation:
From the question, we are informed that Caroline bakes cookies in batches of 24 and that she bakes 3 batches of cookies per week. The amount of cookies baked per week will then be:
= 24 × 3
= 72 cookies
The number of weeks that would take her to bake 2,088 cookies will be:
= 2088 / 72
= 29 weeks

A flat rectangular piece of aluminum has a perimeter of 62 inches. The length is 15
inches longer than the width. Find the width.
Answers
Answer:
Width of rectangular piece = x = 8 inches
Step-by-step explanation:
Perimeter of rectangular piece = 62 inches
Let width of rectangular piece= x
and length of rectangular piece = x+15
We need to find width i.e value of x
The formula used for perimeter of rectangle is: [tex]Perimeter=2(Length+Width)\\[/tex]
Putting values in formula and finding Width:
[tex]Perimeter=2(Length+Width)\\\\62=2(x+x+15)\\62=2(2x+15)\\62=4x+30\\62-30=4x\\4x=32\\x=\frac{32}{4}\\x=8[/tex]
After solving we get value of x = 8
So, Width of rectangular piece = x = 8 inches

how do you determine the quadratic equation having roots that are real numbers and equal
Answers
Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
ANSWER:
when the value of (b^2-4ac) is positive, then the roots are real and distinct.
when it is 0 the roots are equal and if it is negative than its root is not real.
Jamie ran a total distance of 6 and 1 over 2 miles during the months of March and April. If Jamie only ran 1 over 6 mile every day, how many days did she go running?
Answers
Given:
Total distance covered by Jamie = [tex]6\dfrac{1}{2}[/tex] miles
She ran every day = [tex]\dfrac{1}{6}[/tex] miles
To find:
The number of days in which she go for running.
Solution:
Total distance covered by Jamie [tex]=6\dfrac{1}{2}[/tex] miles
[tex]=\dfrac{6\times 2+1}{2}[/tex] miles
[tex]=\dfrac{12+1}{2}[/tex] miles
[tex]=\dfrac{13}{2}[/tex] miles
She ran every day = [tex]\dfrac{1}{6}[/tex] miles
Now,
[tex]\text{Required number of days}=\dfrac{\text{Total distance covered}}{\text{Distance covered each day}}[/tex]
[tex]\text{Required number of days}=\dfrac{\dfrac{13}{2}}{\dfrac{1}{6}}[/tex]
[tex]\text{Required number of days}=\dfrac{13}{2}\times \dfrac{6}{1}[/tex]
[tex]\text{Required number of days}=39[/tex]
Therefore, the required number of days is 39.

Clive and Erica both have part-time jobs where they get paid by the hour. Erica makes more than Clive. The number of dollars, dd, Clive makes in hh hours can be modeled by the equation d=9.5hd=9.5h.
Erica created a graph, with the number of hours she works along the xx-axis and the number of dollars she makes along the yy-axis. Her graph is a line with a slope of 99 and a yy-intercept is 00. Which is a true statement?
Answers
Missing Options:
A. Erica's graph is incorrect, because the slope should be greater than 9.5.
B. Erica's graph is incorrect, because the y-intercept should be greater than 9.5.
C. Erica's graph is correct, because the slope should be less than 9.5.
D. Erica's graph is correct, because the y–intercept should be less than 9.5.
Answer:
A. Erica's graph is incorrect, because the slope should be greater than 9.5.
Step-by-step explanation:
Given
Clive:
[tex]d = 9.5h[/tex]
Erica:
[tex]m = 9[/tex] --- slope
[tex]b =0[/tex] --- y intercept
First, we need to determine the equation of Erica's earnings using
[tex]d = mh + b[/tex]
Where
m = slope = 9
b = y intercept = 0
So, the equation becomes
[tex]d = 9 * h + 0[/tex]
[tex]d = 9h + 0[/tex]
[tex]d = 9h[/tex]
This implies that Erica earns 9 dollars per hour
For Clive:
[tex]d = 9.5h[/tex]
This means that Clive earns 9.5 dollars per hour
From the question, we understand that Erica earns more than Clive.
So, we can conclude that Erica's graph is incorrect because the slope must be greater than 9.5.
When the slope is greater than 9.5, then she earns more than Clive.

In triangle ABC, the measure of angle A is 90°. The length of AB is 1 unit. The length of AC is 8 units. Find the length of BC.
Answers
Given:
In triangle ABC, [tex]\angle A=90^\circ, AB=1\text{ units}, AC=8\text{ units}[/tex].
To find:
The length of BC.
Solution:
Pythagoras Theorem : In a right angled triangle,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
In triangle ABC, angle A is right angle, so BC is hypotenuse.
Using Pythagoras theorem, we get
[tex]BC^2=AC^2+AB^2[/tex]
[tex]BC^2=(8)^2+(1)^2[/tex]
[tex]BC^2=64+1[/tex]
[tex]BC^2=65[/tex]
Taking square root on both sides.
[tex]BC=\pm\sqrt{65}[/tex]
But side cannot be negative, so [tex]BC=\sqrt{65}[/tex].
Therefore, the length of BC is [tex]\sqrt{65}\text{ units}.[/tex]
Using the Pythagorean Theorem, the length of BC is: 8.1 units.
Recall:
Pythagorean Theorem holds true when solving a right triangle that has side c as hypotenuse and side a and b as the other legs, thus: c² = a² + b².
Triangle ABC is shown in the diagram below, where:
m∠A = 90°AB = 1 unit = aAC = 8 units = bBC = ? = c (hypotenuse)Applying the Pythagorean Theorem, the length of BC is solved as follows:
BC = √(1² + 8²)
BC = 8.1 units

========================================================
Explanations:
------------------------------
Part (a)
Applying a rotation will not change the length of XY. This means segment X'Y is the same length as segment XY.
Put another way: (distance from X to Y) = (distance from X' to Y)
So if we have Y as the center of the circle, and XY as the radius, then X and X' are both on the same circle.
------------------------------
Part (b)
As explained in part (a), the segments XY and X'Y are both radii of the same circle, so they are equal to one another.
------------------------------
Part (c)
Draw a right triangle with side lengths XY, X'Y and hypotenuse XX'
Note how a 45-45-90 triangle forms. We can use the pythagorean theorem to show that XX' is larger than XY. Therefore, XX' and XY aren't equal.
------------------------------
Part (d)
This angle forms because we rotated point X 90 degrees with the center point as Y. It might help to think of point Y at the origin. So that's why this statement is true.
------------------------------
Part (e)
This is false because segment X'Y or YX' is a radius and not a diameter. We would need to multiply by 2 to get a diameter.

Sum of the measures is equal to 180° .
So :

Thus :
[tex](5x - 5) + (3 x + 3) + (5x) = 180 \\ [/tex]
Collect like terms
[tex]13x - 2 = 180[/tex]
Add sides 2
[tex]13x - 2 + 2 = 180 + 2[/tex]
[tex]13x = 182[/tex]
Divide sides by 13
[tex] \frac{13x}{13} = \frac{182}{13} \\ [/tex]

Answers
Answer: y= -3x + 2
Step-by-step explanation:
y=mx+b
m= y2-y1 / x2-x1 = -1 - 5 / 1 - (-1)= -6/2 = -3
y=-3x+b
pick a point and solve for b by plugging in the x and y values of that point.
y=-3x+2
explanation: slope intercept form is y = mx + b. the letter m stands for the slope and the letter b stands for the y intercept. the slope is 6/2 and that simplifies to 3. the y intercept is 2 because that’s where the line connects with the y axis
