William buys two bags of peaches and three bags of apricots for $17. Sylvla buys four bags of peaches and two bags of apricots for $22 from the
same store. What is the cost of one bag of peaches?
Answer:
4
Step-by-step explanation:
elimination method2p+3a=174p+2a=22multiply equation [1] by 4 and equation [2] by 2
8p+12a=688p+4a=44 0+8a=24divide both sides by 8
a=3
substitute 3 for a in equation 2 above
4p+[2*3]=224p+6=22take 6 to the other side of the equation
NBthe symbol changes
4p=22-64p=18divide both sides by 4
p=4

A cylinder has a cross-section circumference of 56cm. The height of the cylinder is 3.2cm. Calculate the volume and surface area of the cylinder.
Answer:
volume = 798.58 cm³ (nearest hundredth)
surface area = 678.31 cm³ (nearest hundredth)
Step-by-step explanation:
Volume of a cylinder: [tex]V=\pi r^2h[/tex]
Surface area of a cylinder: [tex]SA=2\pi r^2+2\pi rh[/tex]
Circumference: [tex]C=2\pi r[/tex]
(where r is the radius and h is the height)
Given circumference = 56
⇒ [tex]56 = 2\pi r[/tex]
⇒ [tex]r=\dfrac{56}{2\pi }=\dfrac{28}{\pi }[/tex]
[tex]V=\pi \left(\dfrac{28}{\pi}\right)^2 \times3.2=\dfrac{2508.8}{\pi}=798.58 \textsf{ cm}^3 \textsf{ (nearest hundredth)}[/tex]
[tex]SA=2\pi \left(\dfrac{28}{\pi}\right)^2+56 \times3.2=\dfrac{1568}{\pi}+179.2=678.31 \textsf{ cm}^3 \textsf{ (nearest hundredth)}[/tex]

Answer:
450 - 120 - 80
=250
2/5 × 250 = 100. A
3/5 × 250 = 120 B
Answer:
Grade A 2:9
Grade B 1:3
Grade C 4:15
Step-by-step explanation:
Students in grade A:
[tex]450-(120+80)=450-200=250[/tex]
if the ratio is 2:3 then
[tex]A=(250/5)(2)=(50)(2)=100[/tex] students
The ratio of students with grade A:
[tex]\frac{100}{450}=\frac{10}{45} =\frac{2}{9}[/tex]
= [tex]2:9[/tex]
Students with grade B.
[tex]B=250-100=150[/tex]
The ratio of B:
[tex]\frac{150}{450} =\frac{15}{45} =\frac{1}{3}[/tex]
[tex]= 1:3[/tex]
Ratio of students with grade C:
[tex]=\frac{120}{450} =\frac{12}{45} =\frac{4}{15}[/tex]

36 cm/sec to mph in dimensional analysis
Answer:
There are 2.54 centimeters in an inch. There are 63,360 inches in a mile. So, there are 160,934 centimeters in a mile. There are 3600 seconds in an hour.
36 cm/sec is 36 times 3600 cm/hour = 129,600 cm/hour. Therefore, there are 129,600/160,934 miles per hour = 0.80529 mph
Step-by-step explanation:

The speed from centimeters per second to miles per hour will be 0.805 miles per hour.
What is conversion?Unit modification is the process of converting the size of a given amount between different units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.
The speed is given below.
Speed = 36 cm per second
We know that in 1 centimeter, there are 1 / 160934 miles. And in one second, there are 1/3600 hours.
Then convert the speed from centimeters per second to miles per hour. Then we have
Speed = 36 x (1/160934) ÷ (1/3600)
Speed = 36 x 3600 / 160934
Speed = 129600 / 160934
Speed = 0.805 miles per hour
The speed from centimeters per second to miles per hour will be 0.805 miles per hour.

Based on the different backgrounds and experiences of the leaders, the various leader-client assignments differ in terms of projected completion times. The possible assignments and the estimated completion times in days are as follows.

Develop a network representation of this problem.
The most appropriate client-leader relationship would be leader 1 - Jackson, leader 2 - Ellis, and leader 3 - Smith.
How to represent this problem?To represent this problem we must take into account the data they provide us. Once we see this data, we can infer that the best way to represent it is a bar graph that allows us to compare the data of each project leader with respect to each client.
This graph allows us to draw conclusions about what would be the most efficient way to assign the leaders with the clients. Therefore, the best distribution would be:

True or false: (a) If A2 is defined then A is necessarily square. (b) If AB and BA are defined then A and Bare square. (c) If AB and BA are defined then AB and BA are square. (d) If AB
(a) True. Suppose A is a not a square matrix, with m rows and n columns. Then A² is not defined, because you can't multiply an m×n matrix by another m×n matrix.
(b) False. As an example, consider the matrices
[tex]A_{3\times2} = \begin{bmatrix}1&0\\0&1\\0&0\end{bmatrix}[/tex]
[tex]B_{2\times3} = \begin{bmatrix}-1&0&1\\0&0&1\end{bmatrix}[/tex]
Then both AB and BA are defined, with
[tex]AB_{3\times3} = \begin{bmatrix}-1&0&1\\0&0&1\\0&0&0\end{bmatrix}[/tex]
[tex]BA_{2\times2} = \begin{bmatrix}-1&0\\0&0\end{bmatrix}[/tex]
In general, you can multiply any m×n by any n×m matrix.
(c) True. Multiplying a m×n matrix by a n×m matrix always yields a m×m matrix, and multiplying a n×m matrix by a m×n matrix always yields a n×n matrix.
