Find the value of X and Y
Answers
Answer:
x = 2
y = 152°
Step-by-step explanation:
✔️9x + 10 = 15x - 2 (corresponding angles theorem)
Collect like terms
9x - 15x = -10 - 2
-6x = -12
Divide both sides by -6
x = -12/-6
x = 2
✔️y + (15x - 2) = 180° (same-side interior angle theorem)
Plug in the value of x
y + (15*2 - 2) = 180
y + 28 = 180
y = 180 - 28
y = 152

if y varies inversely with the square of x, and y=6 when x=4, find y when x=0.1
Answers
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 area of Mr. Gonzalez's classroom garden
Answers
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.
Answers
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

The estimated regression equation obtained is :
y = b0 + b1x
b0 = 82.82967
b1 = 3.46061
ŷ = 3.46061X + 82.82967
The change in annual sales for every year of experience is given by the slope value, b1 = 3.46061 = 3.5 (1 decimal place)
The Coefficient of determination R² = 0.8477 = 0.848 ( 3 decimal place).
The Coefficient of determination gives the proportion of explained variance.
About 84.8% percent variation in annual sales can be explained by years of experience of the sales person.
Using the regression equation :
ŷ = 3.46061X + 82.82967
Years of experience, x = 8
ŷ = 3.46061(8) + 82.82967 = 110.514
111 = (to the nearest whole number)

so to average 45mph for 4 hours, he had to drive 4x45 miles total
4x45= 180miles
now we know he drove 120 miles (3x40) in the first 3 hours.
so he drove 180-120= 60 miles in the last hour.
