Answer:
(C)On a coordinate plane, 2 rays form an angle. One ray sits on the x-axis.
Step-by-step explanation:
In the coordinate plane, an angle is said to be in standard position when its value is stated with respect to the x-axis.
Therefore, for an angle to be in a standard position, one of its rays must be on the x-axis.
From the given options, only Option C has a ray that sits on the x-axis. Therefore, it is the only angle in standard position.

The metal strip is sold in lengths of one meter.
Each one meter length of metal strip costs £5.68
Work out the total amount Naher paid.
Answer: £323.76
Step-by-step explanation:
Circumference = 2πr
= 2 x π x 30^2

What is the solution to log2 (9x)- log2^3=3?
x=3/8. x=8/3
x=3
X=9
Answer:
x = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
Using the rule of logarithms
log x - log y = log ([tex]\frac{x}{y}[/tex] )
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
Given
[tex]log_{2}[/tex] (9x) - [tex]log_{2}[/tex] 3 = 3
[tex]log_{2}[/tex] ([tex]\frac{9x}{3}[/tex] ) = 3
[tex]log_{2}[/tex] 3x = 3
3x = 2³ = 8 ( divide both sides by 3 )
x = [tex]\frac{8}{3}[/tex]

The cost of each white tile was £2 the cost of each blue tile was 4 pounds work out the ratio of the total cost of the white tiles to the total of the blue tiles
Answer:
2x/4y = x/2y = x : 2y
Step-by-step explanation:
The question only gave us the cost of each white tiles and blue tiles respectively . The cost of each white tiles is £2 while the cost of each blue tiles is £4. The total cost of the blue tiles and the white tiles can only be calculated if we know the number of blue and white tiles available.
Let us assume
the number of white tiles = x
the number of blue tiles = y
total cost of white tiles = 2 × x = 2x
total cost of blue tiles = 4 × y = 4y
Therefore, the ratio of the total cost of white tiles to the total cost of the blue tiles can be expressed as follows
2x/4y = x/2y = x : 2y
If the number of white and blue tiles is known it can be replaced in the ratio to find the ratio of the total cost of the white tiles to the total cost of the blue cost.

292 and 2092
Step-by-step explanation:
Surface area:
Wall 1: 40 x 3 = 120m^2
Wall2: 40 x 3 = 120m^2
Wall 3: 15 x 3 = 45m^2
Wall 4: 15 x 3 = 45m^2
Ceiling: 15 x 40 = 600m^2
Total : 240 + 600 + 90 = 730
So, cost of painting = 730/25 x 10 = 29.2 x 10 = 292
Total: 292 + 1800 = 2092
The total cost of paint would be 2092 dollars.

A square has a side that measures 5.5 units. What is the area of a circle with a circumference that equals the perimeter of the square? Use 3.14 for π, and round your answer to the nearest hundredth. 38.47 units2 94.99 units2 153.86 units2 379.94 units2
Answer:
Answer choice A) About 38.47 square units
Step-by-step explanation:
Since all four sides of a square have the same length, the perimeter of a square is just 4 times one of the side lengths. The perimeter of the square and therefore the circumference of the circle is 5.5*4=22. The circumference of a circle is 2 times the radius multiplied by pi. The radius of this circle is therefore:
[tex]\dfrac{22}{2\pi}\approx 3.503[/tex]
Since the area of a circle is [tex]\pi r^2[/tex], the area of this circle is:
[tex]\pi \cdot 3.503^2= 3.14\cdot 12.271\approx 38.47[/tex]
Hope this helps!

A semicircle is inscribed in an isosceles triangle with base 16 and height 15 so that the
diameter of the semicircle is contained in the base of the triangle as shown. What is the
radius of the semicircle?
Answer:
7 1/17
Step-by-step explanation:
A figure can be helpful.
The inscribed semicircle has its center at the midpoint of th base. It is tangent to the side of the isosceles triangle, so a radius makes a 90° angle there.
The long side of the isosceles triangle can be found from the Pythagorean theorem to be ...
BC² = BD² +CD²
BC² = 8² +15² = 289
BC = √289 = 17
The radius mentioned (DE) creates right triangles that are similar to ∆BCD. In particular, we have ...
(long side)/(hypotenuse) = DE/BD = CD/BC
DE = BD·CD/BC = 8·15/17
DE = 7 1/17 ≈ 7.059

Answer:
100 sq. m
Step-by-step explanation:
So, first, we need to know the formula for the area of a triangle.
A=BH/2
In this case, we know the base and the height (B and H respectively), and we just fill it out.

Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of 16x2 – 40x + 25 square inches. A square labeled 16 x squared minus 40 x + 25 What is the side length, in inches, of the pet shop sign?
Answer:
length of side of square = (4x - 5) inches
Step-by-step explanation:
We are given;
Area of square = 16x² – 40x + 25
Let's find the roots of this quadratic equation [-b ± √(b² - 4ac)]/2a
Thus;
x = [-(-40) ± √((-40)² - 4(16 × 25)]/(2×16)
x = [40 ± √(1600 - 1600)]/32
x = (40 ± 0)/32
x = 40/32
x = 5/4
Thus, the factors of the polynomial are;
(4x - 5)²
So,
Area = 16x² – 40x + 25 = (4x - 5)²
Since, the right hand side is (4x - 5)² and area of square is (length of side)², thus we can say that length of side of square is (4x - 5) inches
In the picture above, parallel lines p and q are cut by transversal line t. If the measure of angle 4 is 43 degrees, then the measure of angle 6 is 43 degrees and the measure of angle 5 is ______ degrees. The measure of angle 8 is 43 degrees and the measure of angle 1 is _____ degrees.
Answer:
angle 5 is 137 degrees
angle 1 is 137 degrees
Step-by-step explanation:
angle 5 and 6 are supplementary angles meaning together they add up to 180 degrees. to find angle 5 you must find the difference:
[tex]180-43=137[/tex]
so angle 5 is 137 degrees.
likewise, angle 1 and angle 4 are supplementary angles. find the difference:

Compute the probability that exactly 8 of the 20 internet browser users use chrome as their internet browser (to 4 decimals). for this question, if you compute the probability manually, make sure to carry at least six decimal digits in your calculations.
Answer:
2.4%
Step-by-step explanation:
We make use of the binomial probability equation, which is as follows:
P = [n! / (n - r)! r!] p ^ r * q ^ (n - r)
where,
n total number samples = 20
r is the selected number = 8
p, sin este valor no se puede realizar el ejercicio y no lo mencionas, pero encontré una pregunta igual y era de 20.37%, es decir 0.2037
q = 1 - 0.2037 = 0.7963
reemplazando:
P = [20! / ((20 - 8)! * 8!)] * [0.2037 ^ 8 * 0.7963 ^ (20 - 8)]
P = 125970 * 1.92685405*10^-7
P = 0.024 = 2.4%
