Answer:
3. x = 53
4. x = 60
Step-by-step explanation:
Answer:
1. 53
2. 60
Step-by-step explanation:
70+ (4+2x) = 180
74+2x=180
180-74=106/2=53
x=53
2x+x=180
3x=180/3
x=60
4. Which of these points does not lie on the graph of y=-2x+7?
(A) (-1,9
(B) (4,-1)
(C) (-3,1)
(D) (-2.11)
The point (-3,1) is not passing through the graph y = -2x + 7 so option (C) will be correct.
How to plot a graph?
A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given that a line y=-2x+7
Now in order to satisfy any point of this function then the value or
coordinate should satisfy the function or line.
So by checking option (A) 9 = -2(-1) + 7 = 9 so its satisfy.
So all options except (C) are satisfying.
Option (C) ⇒
-2(-3) + 7 ≠ 1
Hence "The point (-3,1) is not passing through the graph y = -2x + 7".

The radius of a circle is 3 m. Find its circumference in terms of pi
Gotcha, bro.
(I don't know what pi is, so I'm gonna assume that it is 3.14)
C=pi x diameter
First, multiply the radius by 2 so you have the diameter.
3x2=6
Second, multiply 3.14 (pi) by 6 (diameter)
3.14x6=18.84
Therefore, the circumference is 18.84.
(19 if you round it to the whole number)
Hope this helps!
(btw if pi is something else, use these steps to help you out)
The circumference of the circle is 6π meters.
What is a circle?A circle is a two dimensional figure with a radius and circumference of 2πr.
We have,
The circumference of a circle is given by the formula:
C = 2πr
where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.
In this case, the radius of the circle is 3 meters.
Substituting this value in the formula, we get:
C = 2πr
C = 2π(3)
C = 6π
Therefore,
The circumference of the circle is 6π meters.

A 9-foot ladder leans against a building six feet above the ground. At what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground?
Answer:
10
Step-by-step explanation:
You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9
The height the 15 ft building touches the building is approximately 10 ft.
The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.
The situation forms a right angle triangle.
Properties of a right angle triangle:One of it angle is equals to 90 degrees.The sides and angles can be found using trigonometric ratios.Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.
Using trigonometric ratios,
let
∅ = angle
tan ∅ = opposite / adjacent
tan ∅ = 6 / 9 = 2 / 3
∅ = tan⁻¹ 0.6666666
∅ = 33.6900672615
Therefore, the height the 15 ft ladder touch building can be calculated as follows:
tan 33.69 = h / 15
h = 15 × 0.66666496431
h = 9.99997446476
h ≈ 10 ft.

Answer:
(a)Yellow=10
Green=38
Relative Frequency of Blue =0.32
Relative Frequency of Red =0.2
Relative Frequency of Green =0.38
(b)50 Red balls
Step-by-step explanation:
In 100 trials, the following were recorded.
Frequency of Blue Balls = 32
Frequency of Red Balls = 20
Relative Frequency of Yellow Balls =0.1
Now, Relative Frequency =Number of Outcome of an Event ÷ Total Number of Trials in the Experiment
Total Number of Trials =100
Therefore:
Therefore, Number of Outcomes of Green balls=100-(32+20+10)
=100-62
Number of Outcomes of Green balls=38
(b)If the Number of Trials is Increased to 250
Expected Outcome of Red Balls =Relative Frequency of Red Balls X 250
She should expect 50 red balls.

Answer:
log(35)/log(7)
Step-by-step explanation:
The change of base formula is ...
[tex]\log_b(a)=\dfrac{\log(a)}{\log(b)}[/tex]
You have b=7, a=35, so the rewrite is ...

If 420 = 120%, what would 100% equal?
Answer:
350
Step-by-step explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
120% = 120/100 = 120 ÷ 100 = 1.2
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 120% of what number = 420?
120% × ? = 420
? =
420 ÷ 120% =
420 ÷ (120 ÷ 100) =
(100 × 420) ÷ 120 =
42,000 ÷ 120 =
350
ProofHow do we check the result?If 120% × 350 = 420 =>
Divide 420 by 350...
... And see if we get as a result: 120%
Note:Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.

A building has 4 stories that are each 15 feet high. A scale drawing has the height of the building at 5 inches.
Which of the following is the correct scale?
1:72
1:12
1:144
5:60
Answer:
1:144
Step-by-step explanation:
if each floor is 15 feet, the whole building is 60 feet tall. so it does have a scale of 5 inches:60 feet but if you simplify that, its 1 inch: 12 feet, so you convert feet into inches by multiplying by twelve, which gives you a scale of 1:144 inches
