Answer:
The cup will be filled 6 times.
Step-by-step explanation:
If her measuring cup only holds 1/4 cups then we need to find how many 1/4 cups are in 3/4 cups:
(1/4) + (1/4) + (1/4) = 3/4
3/4 = 3/4
The measuring cup will have to be filled 3 times for 1 loaf.
If she has 2 loaves that means that she has to fill her 1/4 measuring cup 6 times (because 2 * 3 = 6)
Hope this helps!!

J.B. earns $16.60 an hour with time-and-a-half for hours worked over 8 a day. His
hours for a week are 8.25, 8.25, 9.5, 11.5, and 7.25. Determine his gross earnings
for that week.
Answer:
The gross pay for the week is $701.32
Step-by-step explanation:
J.B. earns $16.60 per hour, and half of it ($16.60/2) for each hour worked over the 8th-hour range.
On the first day, he works 8.25 hours.
We have 8 hours, plus 0.25 hours past the limit, then for the first day he wins:
8*$16.60 + 0.25*($16.60/2) = $134.86
On the second day, he works again 8.25 hours, so he wins the same amount $134.86
On the third day, he works 9.5 hours, then:
We have 8 hours plus 1.5 hours past the limit, then for this day he wins:
8*$16.60 + 1.5*$16.60/2 = $145.25
On the fourth day, he works 11.5 hours, then:
We have 8 hours plus 3.5 hours pást the limit, then for this day he wins:
8*$16.60 + 3.5*$16.60/2 = $161.85
For the last day, he works 7.25 hours, (in this case, we do not have hours worked over the 8-hour limit) then this day he wins:
7.25*$16.60 = $124.50
The gross pay for this week will be equal to:
G = $134.86 + $134.86 + $145.25 + $161.85 + $124.50 = $701.32

The area of a circle is 100π ft². What is the circumference, in feet? Express your answer in terms of π.
Answer:
Answer: 20pi is the circumference
Step-by-step explanation:
The circumference of the circle is 20π ft when the area of the circle is 100π ft².
What is circle?A circle is a locus of the points drawn at an equidistant from a fixed point. The fixed point is called Centre of the circle and the distance from the fixed point to the circle is called radius.
Given, area of a circle is 100π.
Therefore, πr² =100π, where r is the radius of the circle.
So, r²=100
Thus, r= 10 ft.
now, circumference = 2πr
=2π×10
=20π ft.

Can someone help me find the distance between the points (-5,3) and (-4,2)
Answer: 1.4142
Step-by-step explanation:
Input Data :Point 1 (xA,yA) = (-5, 3) Point 2(xb,yB) = (-4, 2)
Objective : Find the distance between two given points on a line?
Formula :Distance between two points = √(xB-xA)^2+(yB−yA)^2
Solution :
Distance between two points = √(−4−−5)2+(2−3)2= √12+(−1)2= √1+1= √2 = 1.4142

Exercise 2.4.2: Proving statements about rational numbers with direct proofs. About Prove each of the following statements using a direct proof. (a) The product of two rational numbers is a rational number. Solution (b) The quotient of a rational number and a non-zero rational number is a rational number. Solution (c) If x and y are rational numbers then is also a rational number.
Answer:
See Explanation
Step-by-step explanation:
(a) Proof: Product of two rational numbers
Using direct proofs.
Let the two rational numbers be A and B.
Such that:
[tex]A = \frac{1}{2}[/tex]
[tex]B = \frac{2}{3}[/tex]
The product:
[tex]A * B = \frac{1}{2} * \frac{2}{3}[/tex]
[tex]A * B = \frac{1}{1} * \frac{1}{3}[/tex]
[tex]A * B = 1 * \frac{1}{3}[/tex]
[tex]A * B = \frac{1}{3}[/tex]
Proved, because 1/3 is rational
(b) Proof: Quotient of a rational number and a non-zero rational number
Using direct proofs.
Let the two rational numbers be A and B.
Such that:
[tex]A = \frac{1}{2}[/tex]
[tex]B = \frac{2}{3}[/tex]
The quotient:
[tex]A / B = \frac{1}{2} / \frac{2}{3}[/tex]
Express as product
[tex]A / B = \frac{1}{2} / \frac{3}{2}[/tex]
[tex]A / B = \frac{1*3}{2*2}[/tex]
[tex]A / B = \frac{3}{4}[/tex]
Proved, because 3/4 is rational
(c) x + y is rational (missing from the question)
Using direct proofs.
Let x and y be
Such that:
[tex]x = \frac{1}{2}[/tex]
[tex]y = \frac{2}{3}[/tex]
The sum:
[tex]x + y = \frac{1}{2} + \frac{2}{3}[/tex]
Take LCM
[tex]x + y = \frac{3+4}{6}[/tex]
[tex]x + y = \frac{7}{6}[/tex]
Proved, because 7/6 is rational
The above proof works for all values of A, B, x and y; as long as they are rational values
In one building, an elevator takes 15 seconds to go up 5 floors.
In another building, an elevator goes up for 60 seconds at the
same rate. How many floors did the elevator in the second
building travel?
Answer:
20 floors
Step-by-step explanation:
15 sec to go up 5 floors is climbing one floor every 3 seconds
3 sec x 20 = 60 seconds
1 fl x 20 = 20 floors

8b. What is the distance from third base to first base?
Home
8c. If the pitcher's mound is 60 ft 6 in from home plate, is it the midpoint of the diagonal from home
plate to second base?
Answer:
Step-by-step explanation:
Distance from home plate to second base = 90√2 feet
Distance from third base to first base = 90√2 feet
60 ft 6 in = 60.5 ft
90√2 /2 = 45√2 ≅ 63.6 ft ≠ 60.5 ft
The pitcher's mound is not at the midpoint.

Zack has an old car. He wants to sell it for 60% off the current price. The market price is $500. How much money would he receive in exchange for the car if he were able to sell it at that rate? What if he wanted to sell it for 25% more than the market price?
60% of 500 is 300
So if Zack wanted to sell the car 60% of the markets price, it would be 300.
125% of 500 is 625
If Zack wanted to sell the car for 25 more than the price at market, it would be 125%, and 125% of 500 is 625.

Given f(x)=x^3-2, find the equation of the secant line passing through (-4,f(-4)) and (2,f(2))
Given:
The function is
[tex]f(x)=x^3-2[/tex]
The secant line passing through (-4,f(-4)) and (2,f(2)).
To find:
The equation of the secant line.
Solution:
We have,
[tex]f(x)=x^3-2[/tex]
At x=-4,
[tex]f(-4)=(-4)^3-2[/tex]
[tex]f(-4)=-64-2[/tex]
[tex]f(-4)=-66[/tex]
At x=2,
[tex]f(2)=(2)^3-2[/tex]
[tex]f(2)=8-2[/tex]
[tex]f(2)=6[/tex]
The secant line passes through the points (-4,-66) and (2,6). So, the equation of the secant line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-66)=\dfrac{6-(-66)}{2-(-4)}(x-(-4))[/tex]
[tex]y+66=\dfrac{6+66}{2+4}(x+4)[/tex]
[tex]y+66=\dfrac{72}{6}(x+4)[/tex]
On further simplification, we get
[tex]y+66=12(x+4)[/tex]
[tex]y+66=12x+48[/tex]
[tex]y=12x+48-66[/tex]
[tex]y=12x-18[/tex]
Therefor, the equation of the secant line is [tex]y=12x-18[/tex].

Answer:
a = 9, c = -4?
Step-by-step explanation:
i think these are the two equations, let me know if i'm wrong
2a + 3c = 5; a + 2c = 1
rearrange second equation : a = -2c +1
plug in:
2(-2c +1) +3c = 5
-4c +1 +3c = 5
-c +1 = 5
-c = 4
c = -4
a + 2(-4) = 1

Find the measure of CD.
mCD= [?] degrees
Given:
A circle with radius 7 units and chord CD = 7 units.
To find:
The measure of arc CD.
Solution:
Let O be the center of the circle.
In triangle OCD,
[tex]OC=7[/tex] (Given)
[tex]OC=OD=7[/tex] (Radii of same circle)
[tex]CD=7[/tex] (Given)
Since [tex]OC=CD=OD[/tex] all sides are equal, therefore, the triangle OCD is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60 degrees. So,
[tex]m\angle COD=60^\circ[/tex]
The measure of central angle is equal to the measure of corresponding arc.
[tex]m(arcCD)=m\angle COD[/tex]
[tex]m(arcCD)=60^\circ[/tex]
Therefore, the measure of arc CD is 60 degrees.
