Answer:
C x = 10 Q = 50
Step-by-step explanation:
supplemantary means adds to 180 deg.
so 130 + 5x = 180
5x = 50 = ang. Q
x = 50/5 = 10 deg.
a rectangular hall is 16 m tall and 12 metre wide. how many marble slabs of size 25 CM X 15cm needed to cover the floor of the hall?
Answer:
5120 tiles.
Step-by-step explanation:
Do one thing.
Find out the area of the rectangular hall.
Find out the area of the marble slab.
Remember, the units are to be made same.
Now, to know the number of marble tiles required to fill the hall, you just have to divide the area of the hall with the area of the marble tile.
Calculations-
Area of the rectangular hall = length x width = 1600 x 1200 (we converted 'm' to 'cm') = 1920000 sq. cm.
Area of one marble tile = 25 x 15 = 375 sq. cm.
Now you divide the numbers and get 5120 tiles.

What is the equation of this line?
A.y=-2x
B.y=1/2x
C.y=1/2x
D.y=2x
Answer:
D. y = 2x
Step-by-step explanation:
The slope of the line is 2, so you get 2x. Therefore, the equation is y = 2x.
Answer:
the equation is answer D
Step-by-step explanation:
the slope is 2 and the y-intercept (b) is zero so it isn't written.

Write the expression as a single logarithm.
log₄ 2x - log₄ 6y
Answer:
[tex]log_{4}(\frac{2x}{6y})[/tex]
Step-by-step explanation:
According to the Quotient Rule (Logarithmic Property):
[tex]log_{a}x - log_{a}y = log_{a}(\frac{x}{y})[/tex]
Therefore, you could combine the logarithmic expressions as:
[tex]log_{4}2x - log_{4}6y = log_{4}(\frac{2x}{6y})[/tex]
Optional:
If ever you're required to simplify it further, [tex]log_{4}(\frac{2x}{6y})[/tex] will be:
[tex]log_{4}(\frac{2x}{6y}) = log_{4}(\frac{x}{3y})[/tex]
The circumference of a circle is defined by the formula C = 2πr. What
formula should Harry use to find the radius if he knows the circumference?
Answer:
r = c/2π

r = C/2π
Billy read an average of 2.5 magazines each week during the year.
Write an equation that represents the amount of magazines that he read (y) per week (x).
Answer: y=2.5x+
Step-by-step explanation:
I dont know the rest because the question is worded wrong
The equation that represents the number of magazines that he read (y) per week (x) will be y = 2.5x.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Billy read an average of 2.5 magazines each week during the year.
The equation that represents the number of magazines that he read (y) per week (x) will be
y = 2.5x
The equation that represents the number of magazines that he read (y) per week (x) will be y = 2.5x.

Kamrynn is looking at her five quiz scores of 96 90 94 93 and 90. Determine the mean rounded to the nearest tenth median mode and range of the results
Answer:
Mean = 90, Median = 93, Mode = 90, Range = 6
Step-by-step explanation:
Mean:
96 + 90 + 94 + 93 + 90 = 463
463 ÷ 5 = 92.5
92.5 to nearest tenth = 90
Mean = 90
Median:
90, 90, 93, 94 ,96
Median = 93
Mode
96, 90, 94, 93, 90
Mode = 90
Range:
96 - 90 = 6
Range = 6

A garden is in the shape of a trapezium whose parallel sides are 40m and 22m and the perpendicular distance between them is 12m. Find the area of the garden
Answer:
A = 372 m²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₁ the parallel bases
Here h = 12, b₁ = 40 and b₂ = 22 , then
A = [tex]\frac{1}{2}[/tex] × 12 × (40 + 22) = 6 × 62 = 372 m²
