What is 70 + 4 rounded to the nearest ten?
Answer:
Step-by-step explanation:
We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4. If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
Answer:
70
Step-by-step explanation:
70+4= 74

4 is four or less so you let it rest by replacing it with a zero.
Answer= 70
Find the solution(s) to the system of equations. Select all that apply.
y=x²-4
y=-x-2
The solution will be the intersection points thus options A (1,-3) and B (-2,0) will be correct.
What is a graph?The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.
For example plot of y = x³ ,y = sinx.
The solution will be the intersection points of both functions.
At the intersection point,
x² - 4 = -x - 2
x² + x - 2 = 0
x² + 2x - x - 2 = 0
x(x + 2) - (x + 2) = 0
(x - 1)(x + 2) = 0
x = 1,-2
At x = 1
y = -1 - 2 = -3 so first intersection is (1,-3)
At x = -2
y = -(-2) - 2 = 0 so second intersection is (-2,0)
Hence "The solution of the given system of equations is (1,-3) and (-2,0)".

April, x, slept 9 hours; Evelyn slept 2/3
less than that.
Evelyn slept _______________ hours. Write the equation as both a decimal and fraction.
Answer:
she slept for 3 hours
Step-by-step explanation:
its actually simple so we know that April slept for 9 hours bug Evelyn only slept 2/3 of 9 hours and if you add 1/3 and 2/3 you get 3/3 which equals a whole so all you have to do is devide 9 into 3 and you get 3 parts with 3 now you add 3 and 3 together and that equals 6 and that was two parts you added which is equaled to 2/3 so all you have to do now is subtract 9-6 and you leave with three which is 1/3 so we come to the final answer she slept for three hours

Find the value of x. If necessary, write your answer in simplest radical form. 30 x 25 x nothing (Simplify your answer. Type an exact answer, using radicals as needed.)
Answer:
x = 38.05
Step-by-step explanation:
Using the Pythagoras theorem to find x
x is the hypotenuse
The other sides are opposite and adjacent
x² = 30²+25²
x² = 900+625
x² = 1525
x = √1525
x = 39.05
What is the area of a semicircle that has a radius of 20 feet?
Answer:
[tex]200\pi[/tex] or 628.3185
Step-by-step explanation:
Area of a semicircle is equal to [tex]\frac{\pi r^{2}}{2}[/tex]. So, when the radius is 20, the area of the semicircle will be [tex]\frac{\pi (20)^{2} }{2} =\frac{400\pi }{2} =200\pi =628.3185[/tex].
What is the absolute value of 17.5?
Answer:
18
Step-by-step explanation:
Rounding it off to nearest 10th place . Since the decimal value is 5 it will round off to +1 , That becomes , 17 + 1 = 18
The absolute value of 17.5 is 17.5
If the radius of Brenda's bicycle wheel is 13 inches, approximately how many inches are there in the circumference of the wheel?
Answer:
There are approximately 82 inches
Step-by-step explanation:
Here, we want to calculate the circumference of the wheel
To do this, we are going to use the formula for the circumference of a circle
C = 2 * pi * r
C = 2 * pi * 13
= 26 * pi
C = 81.7 inches which is approximately 82 inches

The length of two sides of a right triangle are leg: 9 m and hypotenuse: 15 m. Find the length of the third side.
Answer:
Length of Third Side = 12 m
Step-by-step explanation:
You can use the Pythagorean Theorem to solve this: a² + b² = c² or c² - b² = a² in which a and b are legs, and c is the hypotenuse. We use the second equation to solve this: 15² - 9² = a² or 225 - 81 = a². This simplifies to 144 = a². To find a specifically, find the square root of 144, 12.
Hope it helps!

Answer:
g has an average rate of change of zero at the intervals [-5,4] and [-2,2]
Step-by-step explanation:
When we talk of the average rate of change, we mean the change in y values divided by the change in x values
Once the change in y-values is zero, then over that interval, the average rate of change is zero
at the point t =- 5, g(t) = 6; at the point t = 4, g(t) = 6
As we can see here, within the interval [-5,4]; the average rate of change is 0
This same pattern is repetitive at points or ranges where we have same values for g(t)
such as;
[-2,2]

JKLM is a rectangle. if JL = 4x - 12 and MK = x, what is the value of x? what is the length of each diagonal?
Answer:
x = 4
The diagonals are both 4
Step-by-step explanation:
The fact that the two sides have no letter in common indicates that they are opposite each other or a diagonal. In this case the length is a diagonal. Diagonals in a rectangle are equal.
4x - 12 = x Add 12 to both sides
4x - 12 + 12 = x + 12 Subtract x from each side
4x - x = 12
3x = 12 Divide by 3
3x/3 = 12/3
x = 4
One of the diagonals = 4 because it is x.

The inequality is
[tex]-2x+2>3x-8[/tex]
To find:
The solution of the given inequality.
Solution:
We have,
[tex]-2x+2>3x-8[/tex]
Isolate the variables terms on the left side.
[tex]-2x-3x>-2-8[/tex]
[tex]-5x>-10[/tex]
Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.
[tex]\dfrac{-5x}{-5}<\dfrac{-10}{-5}[/tex]
[tex]x<2[/tex]
Therefore, the correct option is D.

Find the mean of the data set shown below. Round to the nearest tenth, if necessary.
This Week's High Temperatures (°F)
29, 38, 45, 31, 50, 58, 62
Answer:
44.7
Step-by-step explanation:
Find the mean of the data set shown below. Round to the nearest tenth, if necessary.
This Week's High Temperatures (°F)
29, 38, 45, 31, 50, 58, 62
The formula for the Mean of a given set of data is
= Sum of terms/ Number of terms
Number of terms = 7
Hence,
Mean = 29+ 38+ 45+ 31+ 50+ 58+ 62/7
Mean = 44.714285714286
Approximately to the nearest tenth= 44.7
