The answer is 3.16
Answer:
8
Step-by-step explanation:
Use Pythagorean theorem a^2 + b^2= c^2.
6^2 + x^2 = 10^2 or 36 + x^2 = 100. Solve for x by subtracting 36 from both sides. X^2 = 64, then take the square root of both sides. X =8

Step-by-step explanation:
A rectangle has an area of 274.5m
One of the sides is 4.5m in length.
Work out the perimeter of the rectangle.
131m
Step-by-step explanation:
274.5÷4.5=61
4.5m×2=9m
61m×2=122
122m+9m=131m
Answer:
Perimeter = 131 m
Step-by-step explanation:
Area=Length x Width so:
274.5 = 4.5 x Width
Width = 274.5/4.5 = 61 m
Perimeter = 2 Widths + 2 Lengths so:
Perimeter = 2(4.5)+2(61 )= 131 m
What are these as equalivalent equations
Answer:
6x - 2(x - 3) and x + 3(x - 2) - 6
The two expresaions that are quivalent are 6x - 2(x - 3) and x + 3(x - 2) - 6.
Step-by-step explanation:
First expression which is 4(x - 3) is an example of a binomial that when multiplied together, the product would be 4x - 12. Therefore, second and third expressions are the answer.

Answer:

Step-by-step explanation:
Round 608,897 to the nearest ten
Answer:
608,900
Step-by-step explanation:
it is hard to explain, but here is the answer
The number 608,897 to the nearest tens is 608,900.
What is Rounding Off?Rounding off is the method of simplifying a number to the next closest number by maintaining it's value.
Rounding can be done for decimals as well as whole numbers. Rounding can be done to different place values like tens, hundreds, and in decimals, tenths, hundredths, etc. can be done.
The given number is 608,897.
We have to round this to the nearest ten.
For that, we have to consider the digits in the place values ones and tens.
The digit in the ones is 7. Replace it with 0.
Since the digit in the ones is greater than 5, the digit in the tens column get increased by 1. So 9 in the tens column become 10. By keeping 0 at the tens column 1 is given to the next place value, hundreds. So the digit on the hundreds value which is 8 get increased by 1 and become 9.
Thus the number 608,897 is rounded to 608,900.
Hence the number 608,897 can be rounded off to the nearest tens as 608,900.

A ball is shot from a cannon into the air. The equation that's gives the height (h) of the ball of any time (t) is: h(t)= -16t^2 + 40t + 1.5
Answer:
26.5 units
Step-by-step explanation:
The height of the ball at any time t is given by :
[tex]h(t)= -16t^2 + 40t + 1.5[/tex] ...(1)
We need to find the maximum height of the ball.
For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]
i.e.
[tex]\dfrac{d( -16t^2 + 40t + 1.5)}{dt}=0\\\\-32t+40=0\\\\t=\dfrac{40}{32}\\\\t=1.25\ s[/tex]
Put t = 1.25 in equation (1) to find the maximum height.
So,
[tex]h(t)= -16(1.25)^2 + 40(1.25) + 1.5\\\\=26.5\ units[/tex]
So, the maximum height reached by the ball is 26.5 units.

A motarcar is running at the rate of 66 km per hour. Each other its wheels makes 500 revolutios per minute. find the radius of the wheel.
Answer:
simple
Step-by-step explanation:
The radius of the wheel can be solved from its given speed and RPM.
Converting km/h to m/min
speed = 66 km / h = 66000 m / 60 min
speed = 1100 m / min
Converting one revolution to meters
1100 m / min = 500 revolution / min ... (given)
500 revolutions = 1100 m
1 revolution = 2.2 m
Solving for the radius of the wheels in meters
1 revolution = 2.2 m
2 * pi * radius = 2.2 m
radius = 2.2 m / 2 * pi
radius = 1.1 m / pi
radius = 0.3501 m

Find the equation of the linear function represented by the table below in
slope-intercept form.
V
5
-10
8
A linear function in slope intercept form is
y = mx + c
To find the equation, you need m and c. This can be found by substituting the points you have.
For example, 5 = -1(m) + c and -7 = 2(m) + c
From here, do simultaneous equations
c = m + 5
-7 = 2(m) + m + 5
3m = -7 -5
m = -4
c = m + 5
c = 1
Rewrite the equation: (This is your answer)
y = -4x + 1

Answer:
7/12
Step-by-step explanation:
the least common denominator is 12
4 goes into 12 three times so you multiply both numbers in 3/4 by three
3/4 = 9/12
6 goes into 12 twice so multiply both the 1 and 6 by two
1/6 = 2/12
so the equation becomes 9/12 - 2/12
subtract the numerators
9-2= 7
7/12 can't be simplified any farther so that's the final answer
Consider U = {x|x is a negative real number}. Which is an empty set? {x|x ∈ U and x has a negative cube root} {x|x ∈ U and x has a negative square root} {x|x ∈ U and x is equal to the product of a positive number and –1} {x|x ∈ U and x is equal to the sum of one negative and one positive number}
Answer:
{x\ x e U and x has a negative square root} is an empty set.
Step-by-step explanation:
If x e U, x is a negative real number, and they don't have a square root (they don't have even roots). Their square roots are complex numbers, not real ones.
The set that will give an empty set will be {x|x ∈ U and x has a negative square root}
What is a set?A set is a collection of numbers or objects. They are not necessarily arranged in pattern.
Given the following sets
r U = {x|x is a negative real number}
We are to determine the set that is empty. This means we need the set of numbers that are not real numbers.
The square root of a negative number will give a complex number. Hence the set that will give an empty set will be {x|x ∈ U and x has a negative square root}

Answer:
C
Step-by-step explanation:
The 3 triangles are all similar.
Using the 2 inside then the ratios of corresponding sides are equal, that is
[tex]\frac{x}{3}[/tex] = [tex]\frac{12}{x}[/tex] ( cross- multiply )
x² = 36 ( take the square root of both sides )
x = [tex]\sqrt{36}[/tex] = 6 → C
Answer:
C) x = 6
because this is a right triangle
=> we have:
(12² + x²)(3² + x²) = (15x)²
<=> 1296 + 153x² + x⁴ = 225x²
<=> x⁴ - 72x² + 1296 = 0
<=> (x² - 36)² = 0
<=> x² = 36

Its extremely simple. You need to start from the lower point, and count up until you get to the same lime as the other point. Starting from the lower point, you count up 4 to get on the same line. Then, since its on the right, you count to the right 5, till you get to the dot, and you get 4/5. All you have to do is just count
Choose the graph that represents the following system of inequalities: y ≤ −3x + 1 y ≤ 1 over 2x + 3 In each graph, the area for f(x) is shaded and labeled A, the area for g(x) is shaded and labeled B, and the area where they have shading in common is labeled AB. Graph of two intersecting lines. Both lines are solid. One line f of x passes through points negative 2, 2 and 0, 3 and is shaded above the line.

One line f of x passes through points negative 2, 2 and 0, 3 and is shaded above the line. The other line f of x passes through points 0, 1 and 1, negative 2 and is shaded below the line.
We want to find the graph of a system of inequalities. We want to select the correct option, but sadly is really hard to interpret the given text, so I will add a graph of the system at the end.
The system is:
y ≤ -3x + 1y ≤ (1/2)*x+ 3To graph these we first need to graph the two lines:
y =-3x + 1
Is a line with a negative slope that passes through the y-axis at y = 1.
Because here we have y ≤ -3x + 1 we know that y must be equal or smaller than the line, thus we need to shade below the line, and because y can be equal to any value in the line we need to use a solid line.
For the other equation:
y = (1/2)*x+ 3
We have a positive slope and this line intercepts the y-axis at y = 3.
Similar as before, here we have y ≤ (1/2)*x+ 3 so the shaded area will be below the line and the line must be solid.
With this in mind, we can graph the system, and you can see it below:

The measures of the three angles whose sum is 160 are in the extended ratio 2:5:9. Find the exact angle measures.
Answer: 20°, 50° and 90°
Step-by-step explanation:
From the question, we are informed that the measures of the three angles whose sum is 160 are in the extended ratio 2:5:9.
The exact angle measures will then be:
= 2/(2+5+9) × 160°
= 2/16 × 160°
= 20°
= 5/(2+5+9) × 160°
= 5/16 × 160°
= 50°
= 9/(2+5+9) × 160°
= 9/16 × 160°
= 90°
