15x+3y=27 into slope-intercept form, simplifying all fractions.
Answers
Answer:
y = -5x + 9
Step-by-step explanation:
Slope-intercept form is the form
y = mx + b
So you need to rearrange the terms to get the y all by itself on the left. On the right, the x term goes first and last the constant (a plain number) see image.

Bob rented a truck for one day. There was a base fee of $14.99, and there was an additional charge of 80 cents for each mile driven. Bob had to pay $114.19 when he returned the truck. For how many miles did he drive the truck?
Answers
Answer:
124 miles
Step-by-step explanation:
$14.99 + ($0.80 x m) = $114.19 (where m is miles driven)
$0.80m = $99.20
m = 124
Q25. The floor of a hall is completely covered by 26 carpets, each
measuring 4m in length and 3m in breadth. What is the area of the
of the hall?
Answers
Answer:
[tex]276m^{2}[/tex] total area. 78m breadth.
Step-by-step explanation:
First, do 4 multiplied by 3 to find the area of one carpet. The answer is 12m. Then, do 12m multiplied by 23 to get the total area. The answer will be 276m squared. If you want to find width then do 3m multipled by 26 which is 78m.

find the area and perimeter of sector OAB given that angle AOB is 60 degrees and the radius of a circle is 21cm
Answers
Answer:
Step-by-step explanation:
Perimeter of a sector
The circumference of a circle is 2 pi r.
pi = 3.14
r = 21 cm
The angle of this particular sector is 60 degrees.
So the formula for this sector is P = 2*r + 60/360 * 2* pi * r
Now all you need do is plug the numbers in.
P = 2 * 21 + 1/6 * 2 * 3.14 * 21
P = 42 + 21.98
P = 63.98
Area of the sector
Area of a circle = pi * r^2
Area of a sector = theta / 360 * pi * r^2
theta = 60 degrees
area of this sector = (60/360) * 3.14 * 21^2
Area of this sector = (1/6) * 3.14 * 441
Area of this sector = 230.79
[tex]\bold{\huge{\pink{\underline{ Solution }}}}[/tex]
Given :-We have given that, Angle AOB is 60° The radius of the circle is 21cmTo Find :-We have to find the area and perimeter of the sector OABLet's Begin :-We have ,
Two radii of the circle OA and OB = 21 cm each [tex]\bold{\angle{ AOB = 60° }}[/tex]AB is the segment of the circleWe know that,
[ Perimeter of sector = Arc length + radius + radius ]
[tex]\bold{\blue{ Perimeter \: of \: Sector = }}{\bold{\blue{\dfrac{\theta}{360°}}}}{\bold{\blue{× 2πr + r + r }}}[/tex]
Subsitute the required values in the above formula :-
Length of the arc of OAB
[tex]\sf{=}{\sf{\dfrac{ 60°}{360°}}}{\sf{×2πr + 2r }}[/tex]
[tex]\sf{=}{\sf{\dfrac{ 6}{36}}}{\sf{×2×21π + 2 × 21 }}[/tex]
[tex]\sf{= }{\sf{\dfrac{1}{6}}}{\sf{ × }}{\sf{\dfrac{22}{7}}}{\sf{× 42 + 42 }}[/tex]
[tex]\sf{= }{\sf{\dfrac{1}{3}}}{\sf{ × }}{\sf{\dfrac{11}{7}}}{\sf{ × 42 + 42 }}[/tex]
[tex]\sf{= }{\sf{\dfrac{1}{3}}}{\sf{× 11×6 + 42 }}[/tex]
[tex]\sf{ = 11 × 2 + 42 }[/tex]
[tex]\sf{= 22 + 42 }[/tex]
[tex]\bold{\red{= 64 \: cm}}[/tex]
Thus, The perimeter of the sector OAB is 64 cm
Now,We have to find the area of sector OAB
We know that,
[tex]\bold{\blue{ Area \: of \: sector = }}{\bold{\blue{\dfrac{\theta}{360°}}}}{\bold{\blue{× πr² }}}[/tex]
Subsitute the required values in the above formula :-
Area of sector OAB
[tex]\sf{=}{\sf{\dfrac{60°}{360°}}}{\sf{× πr² }}[/tex]
[tex]\sf{=}{\sf{\dfrac{6}{36}}}{\sf{× π × 21 × 21 }}[/tex]
[tex]\sf{=}{\sf{\dfrac{1}{6}}}{\sf{× π × 21 × 21 }}[/tex]
[tex]\sf{=}{\sf{\dfrac{1 }{6}}}{\sf{× 441π}}[/tex]
[tex]\sf{=}{\sf{\dfrac{1}{6}}}{\sf{× 441 × }}{\sf{\dfrac{22}{7}}}[/tex]
[tex]\sf{=}{\sf{\dfrac{1}{6}}}{\sf{ × 63 × 22}}[/tex]
[tex]\sf{=}{\sf{\dfrac{1}{6}}}{\sf{× 1386 }}[/tex]
[tex]\bold{\red{= 231 \: cm²}}[/tex]
Hence, The area and perimeter of the sector OAB is 64 cm and 231cm²

2 people share 3 chocolate bars equally. Each chocolate bar is the same size.
About how much chocolate does each person get?
Answers
Answer:
1.5 Pieces
Step-by-step explanation:
If you divide 3 chocolate bars by 2 people it will evenly be distributed by 1.5
Answer:
Just divide it.
Step-by-step explanation:
Take each bar height as 10. There are 3 bars. So the total height is 30. But there is 2 persons, so dividing it will result 15. So according to this assumed answer, I will say you will have to do this :
Give one bar to each of them and the bar should be divided in half, provided that two parts should be there as well as both parts of it should be 5 in height.
So, the upper part was an assume. This time, you mentioned no heights, so I will do it with equation process.
(meaning of each variable)
people = x
chocolate bar = 3
2x ( since 2 people) = 3 ( three chocolate bars )
2x=3
x=3/2
x=1.5 ( one and half )

i) How do you find the sum of the angle measures of any convex polygon?
ii) If the polygon is regular, how do you find the measure of each interior angle in the polygon?
iii) How do you find the sum of the exterior angle measures of any convex polygon?
iv) If the polygon is regular, how do you find the measure of each exterior angle in the polygon?
Answers
Answer:
1) The sum of interior angles of a convex polygon is equal to (n-2) × 180°, where 'n' is the number of sides of the polygon.
2) A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.
4) Irrespective of the number of sides of a regular polygon, the measure of each exterior angle is equal and the sum of the measure of all the exterior angles of the regular polygon is equal to 360°.
