Answer:
A = 9.2 cm²
Step-by-step explanation:
A = 1/2 bh, you know the base = 4.6 and you need to find the height of the triangle.
Drawn the attitude of the equilateral triangle to the base and use a² + b² = c²
c = side of the triangle = 4.6 , b = 1/2 0f 4.6 = 2.3 . the attitude to the base ÷ the base in half.
a² + (2.3)² = (4.6)²
a² + 5.29 = 21.16
a² = 21.16 - 5.29
a² = 15.87
[tex]a = \sqrt{15.87}[/tex]
Now we know the height of the triangle = [tex]\sqrt{15.87}[/tex] , the base = 4.6
A = 1/2bh
A = 1/2 (4.6)([tex]\sqrt{15.87}[/tex] )
A = 9.1625
A = 9.2 cm² or the A of any equilateral triangle = [tex]\frac{\sqrt{3} }{4} s^2[/tex]
A = [tex]\frac{\sqrt{3} }{4} (4.6)^2[/tex]
A = 9.1625
A = 9.2

Answer:
sqrt( 74)
8.602
Step-by-step explanation:
To find the distance between the two points we use the formula
d = sqrt( ( x2-x1)^2 +(y2-y1)^2)
= sqrt( ( 3- -2)^2 + ( -2 -5)^2)
= sqrt( (3+2)^2 + ( -7)^2)
= sqrt( 5^2 (-7)^2)
= sqrt( 25+49)
= sqrt( 74)

A file that is 261 megabytes is being downloaded. If the download is 17.1% complete, how many megabytes have been downloaded? Round your answer to the nearest tenth.
Answer:
44.6 megabytes
Step-by-step explanation:
If 261 megabytes = 100% and we are looking for 17.1% then we can make a cross product.
261= 100
? = 17.1
It means that (17.1x261)/100 = 44.631
If we round our answer it equals 44.6
A quadrilateral has two angles that measure 200 and 30°. The other two angles are in a
ratio of 6:7. What are the measures of those two angles?
Answer:
60 and 70°
Step-by-step explanation:
the angle sum of a quadrilateral is 360
200°+30°+6x+7x=360°
13x=130°
x=10°
1st angle: 10°×6=60°
2nd angle: 10°×7=70°
a joker cap is in the form of a right circular cone of base radius 10.5cm and height 36cm. find the area of sheet to make 20 such caps....?
plz answer this
We know that
l² = r² + h²
l² = (10.5)² + (36)²
l² = 110.25 + 1296
l² = 1406.5
l = √(1406.5)
l = 37.5 cm
Now,
CSA of cone = πrl
=> 22/7 × 10.5 × 37.5
=> 22 × 1.5 × 37.5
=> 1237.5 cm²
Area of 20 caps = 20 × 1237.5
=> 24750 cm²
Answer:
24740 cm²
Step-by-step explanation:
First let us find the slant height (l) of the corn
l² = r² + h²
l² = (10.5)² + (36)²
l² = 110.25 + 1296
l² = 1406.25
l = √1406.25
l = 37.5 cm
Now let us use this formula to find the area of a corn
π r l
π × 10.5 × 37.5
1237.00 cm²
And now let's find the area of 20 caps or corns
1237.00 × 20
24740 cm²

Graph the point (−1, 5/2) on the coordinate plane.
PLEASE HELP ASAP
Answer:
The answer is 2 1/2
Step-by-step explanation:
The graph of point (-1,5/2) will be 1 unit left and 2.5 units up from the origin and has been plotted below.
What are coordinates?A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinate is the denotation of horizontal and vertical distinctions in a coordinate plane with actual distance as per a given scale factor.
The general form of coordinate (x,y) shows x distance far from the origin in the horizontal direction and y distance far from the origin in the vertical direction.
(-1,5/2) → -1 units refer to 1 unit left due to the minus sign.
5/2 = 2.5 its positive so 2.5 units up.
Hence "The graph of point (-1,5/2) will be 1 unit left and 2.5 units up from the origin".

estimate the area of the following irregular shapes
Answer and Explanation: We will find the area of the given shape:
To find the area, we will count the number of squares of the shaded area.
While calculating the area for a more accurate estimate, we count the square as “1” if the shaded region covers more than half of each square. By counting the squares, the area is approximately 50 square units.

Mathematic 19 don’t understand
Answer:
1.75 x 10^3
Step-by-step explanation:
This is quite a simple question really, we just have to remember one thing, the exponent laws. When both exponents have the same base and are getting divided by each other, you subtract the exponents.
So in this case we have 10^8 on top divided by the 10^5 on the bottom, so now you just subtract the 5 from 8 and you get 3 as your final exponent. So your power would just be 10^3.
The final step is just dividing 7 by 4 which is 1.75
Combine the power and 1.75 together to get the correct notation

Find the EXACT distance between the two points.
(9, 31) and (12, 25)
Step-by-step explanation:
the distance between 2 points is the Hypotenuse of a right-angled triangle. its legs are the x and y coordinate differences.
and so, we can use Pythagoras
c² = a² + b²
with c being the Hypotenuse, and a, b being the legs.
so,
the x difference is 9-12 = -3
the y difference is 31-25 = 6
therefore,
distance² = (-3)² + 6² = 9 + 36 = 45
distance = sqrt(45) = 6.708203932...
in a class of 40 students, only 20% of the students are participating in an art competition. how many students are not taking part in the competition?
======================================================
Explanation:
There are two approaches.
Method 1)
20% of 40 = 0.20*40 = 8
Since 8 students are participating, this means 40-8 = 32 are not participating.
-----------
Method 2)
20% are participating, so 100% - 20% = 80% are not participating
80% of 40 = 0.80*40 = 32

Which equation represents a line that is perpendicular to y = 3x - ?
Answer: y=-1/3x+4
Step-by-step explanation:
When a line is perpendicular to another, their slopes will be opposite reciprocals. For example, 1 would be -1, -3 would be [tex]\frac{1}{3}[/tex], and [tex]\frac{5}{1}[/tex] would be -5. The equation is written in slope-intercept form:
y=mx+b
y=3x-4
m is the slope, so next find the equation with the opposite reciprocal of 3, [tex]-\frac{1}{3}[/tex]:
Therefore, y=-1/3x+4 is the correct answer.
