(a) A box has length 50 cm, breadth 20 cm and height 10 cm, then find
(i) its surface area of base;
(ii) its volume
(1000 cm², 100000 cm3)
Answer:
i = 1000cm2
ii = 100000cm3
Step-by-step explanation:
for q i
surface area of base = l* b
= 50* 20
1000cm^2
for q 2
volume l*b*h
= 50*20*10
= 100000cm^3

Carson was shopping online for bow ties to wear with his school uniform he bought a certain number of ties that each cost $12.50 and paid a flat rate of 19 for shipping and handling he has 220 in his bank account before buying the tie write the expression to represent how much money Carson spell on low tide be sure to Define your variable
Given :
Carson was shopping online for bow ties to wear with his school uniform he bought a certain number of ties that each cost $12.50 and paid a flat rate of 19 for shipping and handling.
He has $220 in his bank account before buying the tie.
To Find :
Maximum number of ties he can buy.
Solution :
Let, price of buying x ties is y.
y = 19 + (12.50)x
It is given that he has $200 in his bank account.
So, price of buying tie ≤ $200
y ≤ 200
19 + (12.50)x ≤ 200
(12.50)x ≤ 200 - 19
x ≤ 14.48
Since, number of tie cannot be in decimal.
x ≤ 14
Therefore, maximum tie he can buy is 14.
Hence, this is the required solution.

Use the Distributive Property to simplify 17(2b + 3)
Answer:
34b+51
Step-by-step explanation:
When you distribute, you multiply the number on the outside of the parentheses by everything inside of the parentheses. So...
17(2b+3)
34b+51
Because you can't tell what x is, this is the most simplifying you can do.
Hopefully this helped you out...have an amazing day :3

x3y2-1/4x please solve it fast
Answer:
(x,y) = (0, 1/3)
Step-by-step explanation:
[1] 2x + 3y = 1
[2] 4x - 6y = -2
Graphic Representation of the Equations :
3y + 2x = 1 -6y + 4x = -2
Solve by Substitution :
Solve equation [2] for the variable x
[2] 4x = 6y - 2
[2] x = 3y/2 - 1/2
Plug this in for variable x in equation [1]
[1] 2•(3y/2-1/2) + 3y = 1
[1] 6y = 2
Solve equation [1] for the variable y
[1] 6y = 2
[1] y = 1/3
By now we know this much :
x = 3y/2-1/2
y = 1/3
Use the y value to solve for x
x = (3/2)(1/3)-1/2 = 0

Step-by-step explanation:
A local band is being paid $250 for performing, they receive $2 for each ticket sold.
The chart shows the bands total pay for the first 5 tickets sold.
Tickets sold: Bands pay
1 $250+$2(1)
2 $250+$2(2)
3 $250+$2(3). 4 $250+$2(4)
5 $250+$2(5)
Write an expression for the bands total pay for x number of tickets sold.
Answer:
$250+$2(x) = Total amount paid
Step-by-step explanation:
$250 is the initial amount. They earn $2 per person. The $250 is a flat amount that doesn't change. $2 is paid per person, so you multiply $2 by the amount of tickets sold.
$250 + $2(x) = Total amount paid

Determine the measure of ∠Y. images attached
Answer:
The answer is option CStep-by-step explanation:
Since it's a right angled triangle we can use trigonometric ratios to find the value of ∠Y
To find the value of ∠Y we use tan
We have
[tex] \tan(∠Y) = \frac{25}{20} \\ \tan(∠Y) = \frac{5}{4} \\ ∠Y = { \tan^{ - 1} } \frac{5}{4} \\ ∠Y = 51.34019...[/tex]
We have the final answer as
51.34°Hope this helps you
Answer:
C
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanY = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{XZ}{XY}[/tex] = [tex]\frac{25}{20}[/tex] , thus
∠ Y = [tex]tan^{-1}[/tex] ( [tex]\frac{25}{20}[/tex] ) ≈ 51.34° → C

On their last history test, Eric scored five more than twice the points that his friend Josh did. If they scored 134 points altogether, find Eric’s score
plz i need help ASAP
Answer: Eric got a 91
Step-by-step explanation:
Make two equations:
We know Eric scored 5 points more than 2 times Josh’s score. E=Eric J=josh
Equation: E = 5 + 2(J)
E + J = 134
Solve for E:
J= 134 - E
Plug it into first equation: E= 5+ 2(134-E)
E= 5+(268-2E) add 2E from each side
E+ 2E = 268 + 5 reduce
3E = 273 divide by 3 to find Eric score
E= 91
You can plug it back in to find what josh received 134-91 = 43
To fact check if you multiple josh score of 43 by 2 you receive 86 which is indeed 5 points lower that 91 so it’s correct.

Doug is a zookeeper in charge of monitoring the "aquatic" section at the North End Zoo. A baby dolphin was born on Wednesday and weighed 31 pounds. The dolphin is growing at an average rate of 2.3lbs per day. Write a function that can be used to find the weight, w(x), of the dolphin after x, days.
Answer:
w(x)=2.3x+31
Step-by-step explanation:
From the information given, the function would indicate that the weight of the dolphin after x days would be equal to the 31 pounds the baby weighed when it was born plus 2.3 lbs that is the average rate it is growing for the number of days:
w(x)= 2.3x+31, where:
w(x)= weight of the dolphin
x=number of days
You earn $9.20 per hour at your summer job. Identify an inequality that represents the number p of hours you need to work in order to buy a smart phone that costs $299. Item 6 Question 1 You earn $9.20 per hour at your summer job. Identify an inequality that represents the number p of hours you need to work in order to buy a smart phone that costs $299.
Answer:
32 hours 30 minStep-by-step explanation:
Given that your hourly pay is $9.20
say that you work for p hours, then your pay will be 9.20p
we know that p is the number of hours worked.
therefore, to earn $299 you will need to work
299=9.20p-------1
Solving for p we have to divide both sides by 9.20
299/9.20=p
p=32.5
So you have to work 32 hours 30 min to earn $ 299
The work is doing 32 hours and 30 minutes to earn $ 299.
Given that:
Your hourly pay is equal to $9.20
Assume that you work for p hours, then your pay will be 9.20p
Also know that p is the number of hours worked.
Therefore, to earn $299 you will need to work
299=9.20p (1)
Solving for p we have to divide both sides by 9.20
299/9.20=p
p=32.5
So, to work 32 hours 30 min to earn $ 299.

Which of the following statements demonstrates the identity property of multiplication?
A.-5(18) = -5(20 - 2)
B. (-4)(1) = 4
C.7.-8=.8.7
D.9.(2.7) = (92) - 7
Answer:
B i think
Step-by-step explanation:
The product of 1 and any number is the number (hence why it is most likely b). But instead of it being 4, it would be -4 because multiplying a negative by a positive results in a negative.
