Answer:
5 + 9 = 2(4 - 7.5) = No
Step-by-step explanation:
Add: 5 + 9 = 14
Conversion a decimal number to a fraction: 7.5 = 75/
10
= 15/
2
a) Write down the decimal 7.5 divided by 1: 7.5 = 7.5/
1
b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
7.5/
1
= 75/
10
Note: 75/
10
is called a decimal fraction.
c) Simplify and reduce the fraction
75/
10
= 15 * 5/
2 * 5
= 15 * 5/
2 * 5
= 15/
2
Subtract: 4 - 7.5 = 4/
1
- 15/
2
= 4 · 2/
1 · 2
- 15/
2
= 8/
2
- 15/
2
= 8 - 15/
2
= -7/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(1, 2) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 2 = 2. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - four minus fifteen halfs = minus seven halfs.
Multiple: 2 * the result of step No. 3 = 2 * (-7/
2
) = 2 · (-7)/
1 · 2
= -14/
2
= -7 · 2/
1 · 2
= -7
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-14, 2) = 2.
In words - two multiplied by minus seven halfs = minus seven.
Compare: the result of step No. 1 vs the result of step No. 4 = 14 vs (-7) = No

The radius of a circle is 9 centimeters. What is the length of a 96° arc?
Wrong answer but unique technique to consider: i think i inversed the ratio but i think its right
Pi = circumference/diameter
X/18 centimeters =pi
X is whole circumference 18pi cm you need to convert radians to degrees and get partial arc1 pi is 180 degrees so ratio of
Was the error inverse ratio 96/180?
180/96*18
Error here factor of 72 not 96
18*2*3*3*10/2*3*12 [edit factor should be 2 4 12 ]cancel out factors to reduce
180/4 =45cm
Correction
180*3/4*4
So answers i got are 45 cm corrected as 33.75 cm still way more than total circumference of 18pi 56cmapprox and 9.6cm both are wrong according to calculator online
Please note I canceled out pi by using is degree ratio
Double check i may be wrong
Step-by-step explanation:
Answer:
Solution, we have,
Degree measure ([tex]\theeta[/tex][tex]\alpha[/tex]) = 96° = 96[tex]\pi[/tex]/180
Radius (r) = 9cm
Length of arc (l) = ?
Now,
∝ = l /r
or, [tex]\frac{96\pi }{180}[/tex] =[tex]\frac{l}{9}[/tex]
or, l =[tex]\frac{(96\pi )(9)}{180}[/tex] =4.8[tex]\pi[/tex]cm

What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
On a scale drawing of an office space floor plan, 1 inch represents 3 feet. Then the scale factor is given as,
Scale factor = 3 / 1
Scale factor = 3 feet per inches
The length of the copier room measures 7 inches. Then the number of feet that represents 7 inches is given as,
⇒ 7 x 3
⇒ 21 feet
The number of feet that represents the length of the copier room measures 7 inches on the floor plan will be 21 feet.

Answer
y=5x−10.
Explanation:
The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=3, y1=5, x2=2, y2=0.
Plug the given values into the formula for slope: m=(0)−(5)(2)−(3)=−5−1=5.
Now, the y-intercept is b=y1−m⋅x1 (or b=y2−m⋅x2, the result is the same).
b=5−(5)⋅(3)=−10.
Finally, the equation of the line can be written in the form y=mx+b.
y=5x−10.
Answer:
The slope of the line is m=5.
The equation of the line in the slope-intercept form is y=5x−10.
The equation of the line in the point-slope form is y−5=5(x−3).
The equation of the line in the point-slope form is y=5(x−2).
The general equation of the line is 5x−y−10=0.

Consider the complementary angles shown below. Find the value of x. X + 4 3x + 2
Answer:
x = 21
Step-by-step explanation:
For the complementary angles, the sum of two angles is equal to 90 degrees.
ATQ,
3x+2+x+4 = 90
Taking like terms together,
3x+x+6=90
4x+6=90
4x = 84
x = 21
So, the value of x is equal to 21.

The base of a right prism is a regular hexagon with side 4. The height of the prism is 6. Find the lateral area and volume.
Answer:
(i) The lateral area of the right prism is 144 square units
(ii) The volume of the right prism is 249.42 cubic units.
Step-by-step explanation:
The lateral area of the right prism is calculated as;
Lateral area = perimeter of the base x height
Given;
a side of the hexagon base, s = 4
height of the prism = 6
perimeter of the hexagon = 6s
Lateral area = (6 x 4) x 6
Lateral area = 144 square units
Volume of the right prism is calculated as;
V = base area x height
base area of a hexagon = [tex]\frac{3\sqrt{3} \ \times \ s^2}{2}[/tex]
Volume of the right prism = [tex]\frac{3\sqrt{3} \ \times \ s^2}{2} \ \ \times \ \ h\\\\[/tex]
[tex]V = \frac{3\sqrt{3} \ \times \ (4)^2}{2} \ \ \times \ \ 6\\\\V = 249.42 \ cubic \ units[/tex]
