A rectangular block has square base of area 64 cm². If the thickness of the block is 5 cm, find its total surface area.
Answer:
total surface area of cube is 6 * area of one side
therefore area of one side is given 64cm^2
thickness is also given 5cm .
TSA is 64*5 = 320cm^2
hope it is helpful
Answer:
288 cm²
Step-by-step explanation:
The square base has an area of 64 cm².
That means the sides of the square base measure 8 cm.
The perimeter of the base is P = 4 * 8 cm = 32 cm.
The lateral area is Ph = 32 cm * 5 cm = 160 cm².
The two bases are congruent, and their combined area is 2 * 64 cm² = 128 cm².
The total surface area equals the sum of the lateral area and the area of the bases.
SA = 160 cm² + 128 cm²
SA = 288 cm²
Solve. x-6=-18
A x=-24
B x=-12
C x= 12
D x= 6
x - 6 = -18
x = -18 + 6
x = -12 ← the end
Answer: B)
[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]
[tex] \sf \: x - 6 = - 18 [/tex]
Add 6 to both sides.
[tex] \sf \: x=-18+6 [/tex]
Add -18 and 6 to get -12.
[tex] \boxed{\underline{ \bf \: x=-12 }}[/tex]
=> The correct answer will be Option B - x = - 12

What is the sum of all the positive integers from √24 to √102
Answer:
[tex] \sqrt{24} = 4.9[/tex]
[tex] \sqrt{102} = 10.1[/tex]
positive integers = x
4.9 < x < 10.1
x = 5, 6, 7, 8, 9, 10
sum = 5 + 6 + 7 + 8 + 9 + 10

f(x) = x2. What is g(x)?
Answer:
B
Step-by-step explanation:
Looking at the graph, we can see that g(x) is a compressed version of f(x) in the x direction but stretched in the y direction. We know that it is compressed because the values of g(x) are inside of f(x) in the x direction, and that it is streched because the values of g(x) are higher than the values of f(x) in the y direction.
Next, we want to figure out how much g(x) is a compression/stretch of x.
In the y direction, at x=1, y=1. At x=3, y=9. The ratio between the y values is 9/1 = 9, so in the y direction, the graph is streched by 9.
A stretch in the y direction can be represented by kf(x), with k representing how much the graph is stretched. In our example, k=9, so we have
kf(x) = 9f(x) = 9(x²) = 9x². This is equal to (3x)² = 9x², or B
In the x direction, at x=1, y=1. At x=3, y=9. The ratio between the x values is 3/1 = 3, so in the x direction, the graph is compressed by 3.
f(kx) represents a compression by a factor of k in the x direction, and k =3 here, so we have
f(kx) = f(3x) = (3x)² = 9x² = B

If f(x)=3^x, prove that f(x) + f(x+1)= 4f(x)
Answer:
[tex]f(x) = {3}^{x} \\ f(x +1) = {3}^{(x + 1)} \\ f(x) + f(x + 1) \\ = {3}^{x} + {3}^{(x + 1)} \\ = {(1 \times 3}^{x} ) +( 3 \times {3}^{x} ) \\ By \: taking \: {3}^{x} \: common, \: we \: get \\ (1 + 3) \times {3}^{x} \\ = 4 \times {3}^{x} \\ = 4f(x)[/tex]

Below zero temperature = -12C
Difference= 17 - (-12C)
= 17 + 12 C
=29C
6) find HJ
8)find IK
Answer:
HJ = 17
IK = 30
Step-by-step explanation:
to find HI :
GH : 2
HI : ?
IJ : 12
GI : 7
HI = GI - GH
HI = 7- 2
HI = 5
HI + IJ = HJ
5 + 12 = HJ
17 = HJ
To find IK
IJ = ?
JK = 12
KL = ?
IL = 49
JL = 31
To find IK we need to find KL and IJ
KL = JL - JK
KL = 31 - 12
KL = 19
IJ = IL - (JK + KL)
IJ = 49 - 31
IJ = 18
IK = IJ + JK
IK = 18 + 12
IK = 30
Q. An Umbrella is made by stitching 10 triangular peices of cloth to two different colours, each piece measuring 20cm, 50cm & 50cm. Show much cloth of each colour is required for the umbrella?
Plz answer fast for thanks and brainliest.
Answer:
1000
[tex]1000 \sqrt{6} [/tex]
Step-by-step explanation:
Given: Dimensions of each triangular piece used in umbrella.
Reasoning: By using Heron’s formula, we can calculate the area of a triangle.
Heron's formula for the area of a triangle, Area = √s(s - a)(s - b)(s - c)
Where a, b, and c are the sides of the triangle, and
s = Semi-perimeter = Half the Perimeter of the triangle = (a + b + c)/2
We know that umbrella is made of 10 triangular pieces of cloth of two different colours.
Let us calculate the area of one triangle.
For each triangle, a = b = 50 cm, c = 20 cm
Semi Perimeter
s = (a + b + c)/2
= (50 + 50 + 20)/2
= 120/2
= 60 cm
By using Heron’s formula,
Area of triangle = √s(s - a)(s - b)(s - c)
= √s(s - a)(s - b)(s - c)
= √60(60 - 50)(60 - 50)(60 - 20)
= √60 × 10 × 10 × 40
= 200√6 cm2
Therefore,
Area of 10 triangular pieces = 10 × 200√6 cm2 = 2000√6 cm2
Hence, cloth required for each colour = (Total area of the cloth)/2
= (2000√6)/2
= 1000√6 cm2
Thus, 1000√6 cm2 cloth of each colour is required for the umbrella
please explain if you can
Answer:
Hello again! The answer to this one is C
Step-by-step explanation:
As I said before, a fraction is out of 100, like a percent. Divide 100 by the denominator (in this case, 4). This gives you 75%. However, to convert this into a decimal, we need to multiply it by 0.01. This gives you 0.75.
Answer:
.75
Step-by-step explanation:
there are more that one way to represent numbers..
Roman numerals are quite obsolete, but fractions, decimals and percent's
are the ones that you mainly learn about in a math class...
numbers of one type can be converted to any other...
in this case you want to convert a FRACTION 3/4 to change to a DECIMAL version.... NOTE: at the end I will also show the PERCENT VERSION...
the fraction to decimal conversion is done by "LONG DIVISION"

the temperature for the first 4 days in january was -2 degrees
the mean temperature for the first 5 days in january was 0 degrees
what was temperature on the 5th day ?
URGENT
let's assume the temperature on 5th day be x
We know that :
[tex] \boxed{mean = \frac{sum \: \: of \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]
So,
[tex] \hookrightarrow \: 0 = \dfrac{ - 2 + ( - 2) + ( - 2) + ( - 2) + x}{5} [/tex]
[tex] \hookrightarrow \: 0 \times 5= - 2 - 2 - 2 - 2 + x[/tex]
[tex] \hookrightarrow \: 0 = - 8 + x[/tex]
[tex] \hookrightarrow \: x = 8[/tex]
Therefore, temperature on the fifth day was x = 8
-2(-6n-3)-8=82 solve for n
Answer:
n = 7
Step-by-step explanation:
-2(-6n-3)-8=82,
12n + 6 - 8 = 82,
12n -2 = 82,
12n = 84,
n = 7
Answer:
n=7
Step-by-step explanation:
-2(-6n-3)-8=82
Add 8 to both sides
-2(-6n-3)-8+8=82+8
Simplify
-2(-6n-3)=90
Divided both sides by -2
-2(-6 -3) = 90
2 -2
Simply
-6n-3=-45
Add 3 to both sides
-6n-3+3=-45+3
Divided both side by -6
-6n = -42
-6. -6
Simply
n=7
Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle C?
Enter your answer in the box.
Answer:
C = 80
Step-by-step explanation:
A cyclic quadrilateral is one where all 4 vertices touch the circumference of a circle.
It has 1 interesting property that should concern you: <B + <D = 180 degrees.
3x - 59 + 2x - 1 = 180 Combine like terms
5x - 60 = 180 Add 60 to both sides.
5x = 180 + 60
5x = 240
x = 240/5
x = 48
Now go to 2x + 4.
x = 48
A = 2*48 + 4
A = 96 + 4
A = 100
So C = 180 - 100
C = 80
