The Baking Club is selling pies during lunch to raise money to go to baking competition. Each pie is cut into 8 slices. The club made a certain amount of pies, and the cafeteria staff donated 2 pies. If there were a total of 80 pie pieces to sell, how many pies did the Baking Club make?
Answer:
the baking club made 8 pies
Step-by-step explanation:
80 (the total amount of peices) devided by 8 (the amount each is sliced into) is equal to 10
10 - 2(the two pies donated) = 8
the baking club baked 8 pies

Nikki has $1100 and spends $35 per week. Mich has $520 and saves $55 per week. In about how many weeks, will Nikki and Micah have the
same amount of money?
(round to the nearest whole number)
Answer:
6 weeks
Step-by-step explanation:
Given that :
Nikki :
Initial amount = $1100 ;
Amount spent per week = $35
Mich:
Initial amount = $520
Amount saved per week = $55
Number of weeks they'll both have the same amount :
Let number of weeks = w
For Nikki who is spending :
1100 - 35w - - - (1)
For Mich who is saving :
520 + 55w - - - (2)
Equate (1) and (2)
1100 - 35w = 520 + 55w
1100 - 520 = 55w + 35w
580 = 90w
w = 580 / 90
w = 6.444

At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual.
Answer
The tool set costs $68 during the sale this week.
Explanation
We know that...
Normally the tool set costs $80.
During the sale, the tool set costs $12 less than usual.
So you should subtract to find the cost of the tool set during the sale.
80-12=68
So the tool set would cost $68 during the sale.
Equation Editor The coordinates of points A and B are (−7, 5) and (4, −3), respectively. What is the distance, in units, between the points?
Answer:
√185 = 13.6
Step-by-step explanation:
Distance² = (x' - x)² + (y' - y)²
Distance² = (-7 - 4)² + (5 - -3)² = (-11)² + (8)² = 121 + 64 = 185
Distance = √185

question is attached
Answer:
Please check explanations
Step-by-step explanation:
Mathematically;
csc 2 theta = 1 / sin 2 theta
Sin 2 theta = sin (theta + theta)
= 2sin theta cos theta
So therefore;
csc 2 theta = 1/2(sin theta cos theta)
= 1/2 * 1/sin theta * 1/ cos theta
1/sin theta = csc theta
1/cos theta = sec theta
Thus;
csc 2 theta = 1/2 * csc theta * sec theta
csc 2 theta = 1/2 sec theta csc theta

Find the length of side BC.
Give your answer to 3 significant figures.
С
A
71°
6.3 cm
B
Answer:
19.3 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle B = 71°
Adjacent = 6.3 cm
Hypothenus = BC =?
The length BC can be obtained by using cosine ratio. This is illustrated below:
Cos B = Adjacent / Hypothenus
Cos 71 = 6.3 / BC
0.3256 = 6.3 / BC
Cross multiply
0.3256 × BC = 6.3
Divide both side by 0.3256
BC = 6.3 / 0.3256
BC = 19.3 cm
Thus, Lenght of side BC is 19.3 cm

The average honey bee can travel 10.5 feet per second. How many feet can the honeybee travel in 3.7 seconds?
Answer:
The honey bee would go 38.85 feet if it was traveling at 10.5 feet per second for 3.7 seconds
Step-by-step explanation:
Take the speed the bee is flying (10.5) and times it by the time (3.7) and you get 38.85 which is the answer. 38.85 feet

=================================================
Explanation:
Let y be the unmarked angle to the right of (x+85). Since angle (x+85) and angle y form a straight angle, we know that (x+85)+y = 180.
We also know that y = 60 since line a is parallel to line b, and corresponding angles are congruent when we have parallel lines.
So (x+85)+y = 180 updates to (x+85)+60 = 180
-------
Let's solve for x
(x+85)+60 = 180
x+85+60 = 180
x+145 = 180
x = 180-145
x = 35
Jenny drives from Paris to Rochefort, a distance of 483 km. her average speed on the journey is 84 km/h, she leaves at 9:50. What time does she arrive in Rochefort
The correct answer is 3: 35
Explanation:
To calculate at what time Jenny will arrive in Rochefort, the first step is to calculate the approximate time of the trip. Now, to calculate this consider the time of a movement (t) equals to the distance (d) divided by the speed (s), the process is shown below:
t = 483 km / 84 km/h
t = 5.75 hours
In this number 5 refers to the hours and 0.75 represents 45 minutes considering 0.75 x 60 minutes in one hour = 45 minutes. Therefore, the total time from Paris to Rochefort is 5 hours and 45 minutes. Now, to calculate the time of arrival add this result to the time of departure.
Add the hours: 5 hours + 9 hours: 14 hours
Add the minutes: 50 minutes + 45 minutes =95 minutes
95 minutes are equivalent to 1 hour (60) minutes and 35 minutes
Calculate the total
Hours: 14 hours + 1 hour = 15 hours or 3 in the 12 hour system (15 hours - 12 hours = 3 p.m.)
Minutes: 35 minutes
