-Find the area of Mr. Gonzalez's classroom garden
Answer:
Step-by-step explanation:
We can find the area by breaking this into two rectangles one 3 by 7 and the other 1 by 2. The area of any rectangle is xy where x and y are its dimensions
A=3(7)+1(2)
A=21+2
A=23 yd^2
The area of Mr. Gonzalez's classroom garden is 23 square yd.
What is area?"The space occupied by two dimensional object."
In the rectangle ABDC,
AB = 3yd and BD = 5yd
Formula to find the area of classroom garden
Area of rectangle = length x width
Area of rectangle ABDC = AB x BD
= [tex]3[/tex] ×[tex]5[/tex]
[tex]= 15[/tex]square yd.
In the rectangle EFGC,
EF = 4yd and FG = 2yd
Area of rectangle EFGC = EF x GC
= [tex]4[/tex] × [tex]2[/tex]
= [tex]8[/tex] square yd.
Area of Mr. Gonzalez's classroom garden
= Area of rectangle ABDC + Area of rectangle EFGC
= [tex]15[/tex] + [tex]8[/tex]
= 23 square yd.
Hence, the area of Mr. Gonzalez's classroom garden is 23 square yd.

Ben hires some buses to take 768 people to a football match. Each bus can take 56 people.
Ben hires the least number of buses needed to take all 768 people. Then 19 of the people decide not to go to the football match. Does Ben still need all the buses he has hired? You must show how you get your answer.
Answer:
yes, he still needs all the buses he hired
Step-by-step explanation:
768 people/56 people per bus = 13.71, so 14 buses
768 - 19 = 749 people going
749people/56 people per bus = 13.37, so still need 14 buses
How many moles are in 9.03 x 1023 Li atoms?
please help me
Answer:
1.5 moles
Step-by-step explanation:
number of moles = no. of particles / Avagadro number
therefore, number of moles. = 9.033 * 10^23 / 6.022 * 10^23
therefore, no. of moles = 1.5
There are 1.5 moles in 9.033 * 10^23 Lithium atoms.

Answer:
9600
Step-by-step explanation:
y varies inversely with the square of x
y=k/(x^2)
for some non-zero constant k
y=6 when x=4
6=k/(4^2)
k=96
y=96/(x^2)
x=0.1
y=96/(0.1^2)
y=9600
Find the measure of the indicated angle that makes lines u and v parallel.
Please i really need help
Answer:
1. 135°
2. 114°
3. 118°
4. 81°
Step-by-step explanation:
Let "x" represent the measure of the indicated angle in each problem.
1. x = 135° (corresponding angles theorem)
2. x = 180° - 66° (same-side interior angles theorem)
x = 114°
3. x = 118° (alternate interior angles theorem)
4. x = 81° (alternate exterior angles theorem)

Step-by-step explanation:
A person places $1150 in an investment account earning an annual rate of 5.3%, compounded continuously. Using the formula V = Pe^{rt}V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 10 years.
The amount of money that would be in the investment account with continous compounding would be $12,125.94.
What is the future value of the investment account?The formula for calculating future value when there is continuous compounding is :
A x e^r x N
Where:
A= amount e = 2.7182818 N = number of years r = interest rate1150 x (e^0.053) x 10 = $12,125.94
