Answer:
157.08m²
Step-by-step explanation:
Since the area of a circle is A=πr²
The radius is 10, so
A=π10²
A=314.16 (rounded to nearest hundredth)
Half of that is 157.08.

Through (4,-4) parallel to y=3
Answers
y = -4
Explanation:
The graph of y = 3 is horizontal.
The slope must be 0 for a line to be horizontal, and thus parallel to y=3.
In slope-intercept form (y = mx + b), “m” is the slope, “b” is the y-intercept.
When the slope, m = 0, the equation becomes y = b.
Point (4,-4) is written (x, y).
y = -4
Since y = b, b = -4.
Therefore, the equation is y = -4.
Answer:
y = -4
Step-by-step explanation:
Because y = b, b = -4, the equation would be written as y = -4.

A fair dice has six sides, numbered 1 to 6
After it is rolled, five of the numbers can be seen.
a) Write down the probability that one of these five numbers is 3
b) Work out the least possible sum of the five numbers
Answers
(a). The probability that one of these five numbers is 3 is [tex]\frac{5}{6}[/tex].
(b). The least possible sum of the five numbers is 15
Probability:Probability is the ratio of number of favourable outcomes to the total number of outcomes.
When a fair dice has six sides, numbered 1 to 6 ,After it is rolled, five of the numbers can be seen.
The probability that one of these five numbers is 3 is computed as,
[tex]P(E)=\frac{5}{6}[/tex]
The least possible sum of the five numbers, when the number 6 is hidden.
Least sum = 1 + 2 + 3 + 4 + 5 = 15

a) (-317) < 603
b) (-333) < (-777)
c) 630 > 234
d) 1250 > (-750)
Answers
Answer:
the false statement would be option b) (-333) < (-777).
Step-by-step explanation:
in negative numbers, the smallest negative number would be considered larger when compared to a large negative number. additionally, when you plot these numbers on a number line, it is evident that -333 would be closest to 0, and -777 would be the farthest. thus, -333 is larger than -777.

Calculate the distance between the points J=(4, -2) and E = (7. – 7) in the coordinate plane.
Give an exact answer (not a decimal approximation).
Answers
Answer:
Step-by-step explanation:
√[(7-4)^2+{-7-(-2))^2] = √36 = 6
The distance between the points J=(4, -2) and E = (7. – 7) in the coordinate plane is 6.
What is coordinate plane ?"A coordinate plane is a two-dimensional plane formed by the intersection of two number lines. One of these number lines is a horizontal number line called the x-axis and the other number line is a vertical number line called the y-axis. These two number lines intersect each other perpendicularly and form the coordinate plane.
The plane is called two-dimensional because anywhere on this plane where you can put your finger, the location of that point will need two things– its distance on the x-axis and its distance on the y-axis."
Using the distance formula between the points
Given, J = (4,-2) and E = (7,-7)
Distance formula = [tex]\sqrt((x1 - x2)^2 -(y1 - y2)^2)[/tex]
[tex]= \sqrt((4-7)^2 + (-2 - (-7))^2)\\\\= \sqrt(9 + 25) = 6[/tex]
Hence, distance between the points J and E = 6

the triangle Loom is made from wood strips shaped into a 45 45 90 triangle. pegs are placed every half inch along the hypotenuse and every quarter inch along each leg. suppose you make a loom with an 18 inch hypotenuse. approximately how many pegs will you need
Answers
Answer:
36 pegs (for the hypotenuse)
About 51 pegs (for the legs)
138 pegs (total)
Step-by-step explanation:
Along the hypotenuse, the pegs are placed every half-inch. That would make 2 pegs per inch. Multiply 2 x 18 to get 36.
The legs are each 9 sqrt 2. This is 12.7279220614. The pegs are placed at each quarter inch for the legs. This is 4 per inch. So multiply 12.7279220614 x 4 to get 50.9116882454. Round this to 51.
Add 51 + 51 for the legs total pegs. You get 102. Add 102 + 36 to get 138 pegs total.

A wire is attached to the top of a tower and to a point on the ground that is 35 m from the base of the tower. If the wire makes a 65 degree angle with the ground, how long is the wire? Round your answer to the nearest tenth
Answers
Answer:
83 m
Step-by-step explanation:
The computation of the length of the wire is shown below:
Let us assume the length of the wire be x
Given that
There is 35m from the base of the tower
And, the angle with the ground is 65 degree
So, the length of the wire is
cos 65 = 35 ÷ x
x = 35 ÷ cos 65
= 83 m
