Answer:
solution:-
diameter of a cylinder (d) = 12 cm
length(h) = 30 cm
curved surface area of cylinder (csa) = ?
we know that ,
therefore , csa of cylinder = 2πrh
r = d/2
or, r = 12/2= 6 cm
Then, csa if cylinder = 2 ×22/7×30
= 2×22×30/7
= 1320/7
= 188.57 Square cm Ans,......

Which statement can be represented by the equation Two-fifths x + 9 = 9?
Two-fifths of nine is a number.
Two-fifths of a number is nine.
Nine more than two-fifths of a number is nine.
A number plus nine is the same as two-fifths of nine.
Given:
The equation is
[tex]\dfrac{2}{5}x+9=9[/tex]
To find:
The statement for the given equation.
Solution:
For "more" or "plus" we use "+" sign.
For "of" we use "×" sign.
Let x be the unknown number.
Two-fifths of nine is a number.
[tex]\dfrac{2}{5}(9)=x[/tex]
Two-fifths of a number is nine.
[tex]\dfrac{2}{5}x=9[/tex]
A number plus nine is the same as two-fifths of nine.
[tex]x+9=\dfrac{2}{5}(9)[/tex]
These equation are different from the given equation. So, the options A, B and D are incorrect.
Nine more than two-fifths of a number is nine.
[tex]\dfrac{2}{5}x+9=9[/tex]
It is same as the given equation. Therefore, the correct option is C.

Step-by-step explanation:
The perimeter of a triangle is the sum of the measures of the three sides.
For this triangle,
perimeter = PQ + QR + PR
We know PQ = 6, and QR = 4.
perimeter = 6 + 4 + PR
perimeter = PR + 10 Equation 1
We can find the perimeter using the given information.
perimeter = 3 * PQ
perimeter = 3 * 6
perimeter = 18
Now we replace perimeter with 18 in equation 1 and solve for PR.
18 = PR + 10
Subtract 10 from both sides.
8 = PR
Answer: PR = 8

Write an equation of the line passing though the point (4,3) that is parallel to the line y= 6x-3
Answer:
y=6x-21
Step-by-step explanation:
Parallel lines have equal slope i.e,6 for this equation.
Introduce points x,y aside 4,3 and equate
y-3/x-4=6
y-3=6(x-4)

Blake and two of his friends are going to an amusement park. The cost of admission to the park is $39.95 per person. Once they are in the park, Blake and his friends ride the race cars, which require an additional fee. If the total amount spent by all three boys is $143.70, then what is the additional fee to ride the race cars?
Answer:
$23.85
Step-by-step explanation:
39.95 x 3 which can also be 39.95 + 39.95 + 39.95=119.85
So then do 143.70-119.85 to find the answer which is 23.85.
Answer:
$23.85
Step-by-step explanation:
Take $39.35 and multiply x3
(39.35 x 3) OR (39.35 + 39.35 + 39.35)
Then take $143.70 and subtract.
($143.70 - $119.85)
= $23.85

If a 20-foot tree casts a shadow of 15 ft how long is the shadow of a student who is 5 ft 4 in tall?
Answer:
4 feets
Step-by-step explanation:
Given that :
Height of tree = 20 feets
Shadow of tree = 15 ft
Height of student = 5ft 4 in ; 4 in = 0.3333 foot = 5.3333 feet
Shadow of student = s
Height of tree / shadow of tree = height of student / shadow of student
20 / 15 = 5.33333 / s
Cross multiply :
20 * s = 15 * 5.33333
s = 79.99995 / 20
s = 3.9999975
Shadow of student =, 4 feets

Answer:
y=6/7x+11/7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-5)/(-3-4)
m=-6/-7
m=6/7
y-y1=m(x-x1)
y-5=6/7(x-4)
y=6/7x-24/7+5
y=6/7x-24/7+35/7
y=6/7x+11/7

Which shape has 5 faces, 8 edges and 5 vertices? A. triangular pyramid B. rectangular pyramid C. rectangular prism D. triangular prism
Answer:
Rectangular Pyramid
Step-by-step explanation:
Rectangular Pyramid-It has 5 faces, 8 edges and 5 vertices.
Answer:
C. Rectangular Pyramid
Step-by-step explanation:
Faces:
A rectangular pyramid has a rectangle as its base. So from it's pinnacle to each of the rectangle's edges, there is a triangular face. As the base has 4 sides, it should have 4 such faces. And the base rectangle is also a face. So it has a total of 5 faces.
So, the number of faces [tex]$F$[/tex] = 5
Edges:
And from its pinnacle to 4 base vertice there are 4 edges. And the base rectangle has four edges. So there are a total of 8 edges
So, the number of edges [tex]$E$[/tex] = 5
Vertice:
The number of vertices [tex]$V$[/tex] must be 5. Becaue we know by Euler's formula [tex]$V + F - E = 2$[/tex] which holds for any shape that doesn't have any hole within it. And 5 is the only value for [tex]$V$[/tex] that satisfies the equation.
So we can conclude that, the shape must have to be rectangular pyramid.
