Answer:
3x + 8.75 Or 3x + ³⁵⁄₄Explanation:
I'm going to convert all the fractions into decimals⁻¹⁄₂x + 9.5 + x - ¾ + 2.5x
= -0.5x + 9.5 + x - 0.75 + 2.5xGroup like terms-0.5x + x + 2.5x + 9.5 - 0.75
Add similar elements: -0.5x + x + 2.5x = 3x= 3x + 9.5 - 0.75
Add / subtract: 9.5 - 0.75 = 8.753x + 8.75 Or 3x +³⁵⁄₄- PNW
Describe how to transform (^6 sqrt x^5)^7 into an expression with a rational exponent. Make sure you respond with complete sentences.
Answer:
[tex]x^{\frac{36}{5} }[/tex]
Step-by-step explanation:
The transformation is as follows:
As we know that
[tex]a^{\frac{m}{n} } \rightarrow\sqrt[m]{a^{n}} \\\\\sqrt[m]{a^{n}} \rightarrow a^{\frac{m}{n} }\\\\(\sqrt[6]{x^5})^7 \rightarrow (x^{\frac{5}{6} })^7 \rightarrow x^{\frac{5^\times 7}{6} }\\\\x^{\frac{36}{5} }[/tex]
In this way it would be transformed with a rational exponent

PLEASE HURRY! 15 points
Answer:
The answer should be C
Step-by-step explanation:
Consider the following sequence:
7, 11, 15, 19, 23, . . .
The common difference is ______
What is the Explicit equation for the sequence?
t(n) = ____n + ______
What is the 20th term?
Answer:
Common difference= 4, Equation; t(n)=4n+3, 20th= 83
Step-by-step explanation:
d=11-7=4
Equation
Recall, t(n)=a_1+(n-1)d
Replacing a_1 =7 and d=4
t(n)=7+(n-1)4
t(n)=7+4n-4
t(n)=4n+3
20th item
t(20)=4(20)+3=83
I hope that is helpful
Answer:
Step-by-step explanation:
This is an arithmetic progression.
It starts at 7 and keeps on adding 4.
The common difference is 4
The explicit equation is
t_n = a + (n - 1)*d
a = 7
d = 4
t_n = 7 + (n - 1)*4
t_n = 7 + 4n - 4
t_n = 4n + 3
t_20
t_20 = 4*20 + 3
t_20 = 83
Building A is 883 feet tall and contains 70 stories. Building B contains 104 stories. If the two buildings have the same number of feet per floor , approximate the height of building B
Answer:
1311.88
Step-by-step explanation:
Feet:stories
883:70
x:104
To solve this we need to multiply 883 by 1.48 because this is what we multiplied 70 to get to 104
x=1311.88=1312

1. The perimeter of a sector of a circle of radius r is 8 metres.
(i) Express θ in terms of r, where is the angle of the sector
in radians, as shown.
Answer:
Step-by-step explanation:
s and r are the arc length and radius, respectively.
perimeter of sector = s+2r = 8
s = 8-2r
θ = s/r = (8-2r)/r

can I get some help with changing the decimal 1.5 to a fraction please
Answer:
I do believe that 1.5 as a fraction is 3/2 or 1 and 1/2
Step-by-step explanation:
Hope this helps you:)
Answer:
1 ½ or 3/2
Step-by-step explanation:
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction. - Khan Academy

1. A field in the form of a parallelogram has one
diagonal of 42 m long and the perpendicular
distance of this diagonal from either of the
outlying vertices is 10 m as shown in the figure.
Find the area of the field.
Answer:
420m²
Step-by-step explanation:
Given that:
Length of diagonal = 42m
Lenght of outlying vertice = 10 m
Area of paralellogram = 2 " (area of triangle)
Area of triangle = 1/2 * base * height
Hence,
Area of parallelogram :
Area = 2(0.5 * 42 * 10)
Area = 2 (210)
Area = 420m²
please help me on this
In the right triangle, if a = 3 and b = 6, what is the value of c?
a 3 times the square root of 5
b 9
c 9 times the square root of 5
d 45
Answer:
A
Step-by-step explanation:
Using the pythagorean theorem, [tex]a^{2} +b^{2} =c^{2}[/tex]
we plug the numbers in; [tex]3^{2} + 6^{2} =c^{2}[/tex]
9+36=c^2
45=c^2
sqr root of 45 is [tex]\sqrt{45}[/tex]
next find the positive perfect sqr root of 45 which will be 9.
9 goes into 45 5 times so it will be [tex]\sqrt{9x5}[/tex]
Sqr root of 9 is 3 so it will be [tex]3 \sqrt{5}[/tex]
Using the given diagram, solve for x.
x=
Step-by-step explanation:
since the whole biggest triangle is a right triangle so ,
[tex] {x}^{2} = {20}^{2} + {18}^{2} \\ {x}^{2} = 400 + 324 \\ {x}^{2} = 724 \\ x = \sqrt{724} = 26.907 = 26.91[/tex]

Answer:
Step-by-step explanation:
1. 24+9/2pi, 2. 51 3. 86. 4. 90 5. 56, all of these are done with the addition or subtraction of simple geometric formulas such as those for a rectangle,circle or triangle.
Answer:
Step-by-step explanation:
1. Rectangle + Semi-Circle
[tex]A = a*b + \frac{\pi r^{2}}{2}\\a=6, b=4, r=\frac{a}{2} = 3\\A = 24 + 4.5 \pi = 38.14 in^{2}\\[/tex]
2. Large Rectangle - Small Rectangle
[tex]A = 15 * 5 - 6*3 = 75 - 18 = 57 in^{2}\\[/tex]
3. Rectangle - Trapezoid
[tex]A = a * b - \frac{c+d}{2}h = 20*17 - 6 * \frac{6+12}{2} = 340 - 54 = 286 cm^{2}\\[/tex]
4. The composite figure is a rectangle if the triangle is moved to left and fills the missing part
[tex]A = a * b = 10 * 9 = 90 m^{2}\\[/tex]
5. Square - Triangle
A = [tex]A = a^{2} - \frac{b^{2}}{2} = 8 * 8 - \frac{4 * 4}{2} = 64 - 8 = 56 cm^{2}\\[/tex]
6. Circle - Square
[tex]A = \pi r^{2} - a^{2} = 64 \pi - 12 * 12 = 64 \pi - 144 = 57.06 m^{2}[/tex]
7. Square - Triangle
[tex]A = a^{2} - \frac{b*h}{2} = 15 * 15 - \frac{10 * 8}{2} = 225 - 40 = 185 sq.ft.[/tex]
8. Rectangle + Triangle
[tex]A = a *b + \frac{a*h}{2} = 9.5 * 9 + \frac{9.5*12}{2} = 85.5 + 57 = 142.5 in^{2}\\[/tex]
9. Triangle + Rectangle
[tex]A = \frac{a*b}{2} + c * d = \frac{12*10}{2} + 12 * 6 = 60 + 72 = 132 sq.ft.[/tex]
10. Rectangle + Quarter Circle
[tex]A = r * b + \frac{\pi r^{2}}{4} = 6 * 8 + \frac{36 \pi}{4} = 48 + 9 \pi = 76.27 in^{2}\\[/tex]
11. Square + Rectangle
[tex]A = a^{2} + b * c = 7 * 7 + 9 * 14 = 49 + 126 = 175 m^{2}[/tex]
12. Rectangle - 2 * Square
[tex]A = a * b - 2 * c^{2} = 25 * 18 - 2 * 8 * 8 = 450 - 128 = 322 sq.ft.[/tex]
13. Trapezoid
[tex]A = \frac{a+b}{2} * h = \frac{10+15}{2} * 15 = 12.5 * 15 = 187.5 sq.ft.[/tex]
14. Trapezoid - Rectangle
[tex]A = a * h - c * d = 12 * 7 - 9 * 5 = 84 - 45 = 39 in^{2}[/tex]
15. Rectangle - Triangle
[tex]A = a * b - \frac{a * b}{2} = \frac{a*b}{2} = \frac{10 * 20}{2} = 100 in^{2}[/tex]
16. Square + Trapezoid
[tex]A = a^{2} + \frac{a + b}{2} * h = 25 + \frac{5 + 9.5}{2} * 6 = 25 + 43.5 = 68.5 in^{2}[/tex]

Prove: The difference of the cubes of two
successive integers is odd.
(n + 1)3-n3 = [ ? ]n2 + [ ]n + 1
= [ ](n + 1) + 1
= 6m + 1 (since n or n+1 is even)
= odd
(n + 1)³ - n³ = (n³ + 3n² + 3n + 1) - n³
… = 3n² + 3n + 1
… = 3n (n + 1) + 1
… = 6m + 1
where m is another integer. We can say this because, as the second-to-last step says, either n or n + 1 is even, which makes their product also even, so we can write it as a multiple of 2:
n (n + 1) = 2m
Then 6m is even, and adding 1 to it makes it odd.
Write an equation of the line that passes through the points (0,4) and (2,10).
Answer:
y = 3x+4
Step-by-step explanation:
Use the coordinates of the points to find the slope of the line passing through them.
slope = Δy/Δx = (10-4)/(2-0) = 6/2 = 3
Point-slope equation for line of slope 3 that passes through (0,4):
y-4 = 3(x-0)
Slope-intercept form of the equation:
y = 3x+4
