Answer:
25.4
Step-by-step explanation:
If double of the number 'x' is 50.8, (2x=50.8)
Then the original number must be half of that value, (x=50.8/2)
50.8/2 = 25.4
2. At the grocery store checkout, you watch at the register as it rings up your purchases and coupons. The prices are as follows: $2.35 $1.17 $6.31 $1.75 $3.15 $8.79 $1.59 − $0.50 (coupon) − $1.00 (coupon) The register gives your total bill as $23.61 (a) Round each price and coupon to the nearest dollar and then estimate the total amount of the bill. (b) Using your estimate, determine whether the total on the register is reasonable. Justify your answer. Answer:
Answer:
Rounding goes up to the next number when a number is 5-9.
-$3
-$1
-$5
-$2
-$3
-$9
-$1
- $1 off (coupon)
- $1 off (coupon)
Rounded Total: $22
Exact Total: $21.77
B) The total on the register is reasonable because even with the rounded price at the end, it is only 23 cents off, which is good.

Given the circle below with tangent \overline{NO} NO and secant \overline{QPO} QPO . If QP=9QP=9 and QO=14QO=14, find the length of \overline{NO} NO . Round to the nearest tenth if necessary. Q
Given that that the lengths of the parts of the secant are, QO = 14 and QP = 9, we have that the tangent, NO = 17.9
How can the length of the tangent be found?
The given parameters are;
Length of side, QP = 9
Length of QO = 14
Required;
The length of;
[tex] \overline{no}[/tex]
From the tangent and secant formula, we have;
[tex] { \overline{no}}^{2} = { \overline{qo}} \times ( { \overline{qp} \: + { \overline{qo}}})[/tex]
Which gives;
NO^2 = 14 × (9 + 14) = 322
NO = √(322) = 17.9

show that the area of a square A inscribed in a circle with radius r is A=2r square
Answer:
see below and see image.
Step-by-step explanation:
"inscribed" means the four corners (vertices) of the square are on the circle.
The diagonal of the square is the diameter of the circle. Use special right triangles or pythagorean thm to find the side length of the square in terms of r. Use Area formula for a square:
A = s^2 OR s×s

What is the y intercept of the line -9 + 3y= 18
Answer:
0,9
Step-by-step explanation:
Answer:
y=9
Step-by-step explanation:
In this equation you would add 9 to get the y on a side by itself that would get you 3y=27, then you would divide both sides by 3 and end up with your y-intercept to be 9.

Which number is an irrational number?
Answer:
D. [tex]\sqrt[3]{16}[/tex]
Step-by-step explanation:
What is an irrational number?
❖ An irrational number is a number that cannot be written in fraction
form. They're also non-terminating and non-repeating decimals.
Determing Irrational or Rational
A.
The square root of 100 is 10 because 10 × 10 = 100. 10 can be written as a fraction of 10/1, so it's rational.B.
1/8 is already in fraction form, so it's rational.C.
-2.2675 is a terminating decimal, so it's rational.D.
The cube root of 16 is irrational because there is no exact number that multiplies itself 3x to get 16. Additionally, when you put the cube root of 16 in a calculator, you will get a mess of decimal digits, thus forming a non-repeating and non-terminating decimal.Janice is cutting ribbon to decorate a present.

Zoe says an equilateral triangle is always an acute triangle, but an acute triangle is never an equilateral triangle. Which statement explains whether Zoe is correct or not
Answer:
Zoe is correct!
Step-by-step explanation:
The definition of an acute triangle is that all three angles are less than 90 degrees. An equilateral triangle has the angles 60, 60, and 60. All three are less than 90 degrees, so this means that an equilateral triangle is always an acute triangle.
However, that doesn't necessarily mean that an acute triangle is always an equilateral triangle.

Find the speed of a dog running 135 meters (m) to the right in 16s.
Based on the calculations, the speed of the dog is equal to 8.44 m/s.
Given the following data:
Distance = 135 meters.Time = 16 seconds.To calculate the speed of the dog:
What is speed?Speed can be defined as the distance covered by an object or living organism per unit of time. Thus, speed can be measured as meter per seconds.
Mathematically, speed is given by this formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Speed = \frac{135}{16}[/tex]
Speed = 8.44 m/s.

The diameter of a circle is 2 centimeters. What is the circle's area?
Answer:
3.14 cm²
Step-by-step explanation:
Given :-
Diameter = 2 cm
To Find :-
Area
Formula Required :-
Area (circle) = πr²
Solving :-
Area = 3.14 x 1 x 1
= 3.14 x 1
= 3.14 cm²
Solution :-
3.14 cm²
Solution:
We know that:
Diameter of circle = 2 cmRadius = Diameter/2Area of circle = πr²Finding the radius.
Radius = Diameter/2=> Radius = 2/2=> Radius = 1 cmFinding the area.
Area of circle = πr²=> Area of circle = 3.14 x 1²=> Area of circle = 3.14 x 1 = 3.14 cm²Students of Jesus and Mary were divided into 6 teams for a football game. if the school comprises of 3,900 students,how many students can be found on each team?

I need the answer for this equation
Answer:
10 is the answer
Step-by-step explanation:
Let squares be x, triangles be y and circle be z
Now,
x³ = 27
so, x = 3
Now,
x * y * y * y = 24
or, 3 * y³ = 24
or, y³ = 24/3
so, y³ = 8
so, y = 2
Again,
x * y * z² = 96
or, 3 * 2 * z² = 96
or, 6z² = 96
or, z² = 96/6
so, z² = 16
so, z = 4
Now,
z + x*y = 4 + 3*2 = 4 + 6 = 10

1.2 3 4 5 X
-5 4 3 2 -1,
-2-
IN TY
Answer:
the first : all real numbers
Step-by-step explanation:
the domain is the interval or set of all valid values for x.
reflecting the graph over the x-axis simply means to multiply the original function by -1.
that does not change the domain in any case. it only changes the range (the interval or set of possible y values).
so, the domain is the same as for the original function : all real numbers.
Find the monthly interest payments in the situation described. Assume that monthly interest rates are 1/12 of annual interest rates

The monthly interest payment is: B. $12.50.
Monthly interest paymentFirst step is to find the average monthly interest rate
Average monthly interest rate=1/12× 15%
Average monthly interest rate= 1.25%
Second step is to calculate the monthly interest payments
Monthly interest payments=1.25%× $1,000
Monthly interest payments=$12.50
