Answer:
x = 30.5
Step-by-step explanation:
cos(18º) = 29/x
Multiply both sides by x and divide both sides by cos(18º) to get
x = 29/cos(18º)
x = 30.5
What is the exact circumference of the circle?
Answer:
circumference = 22.2144 or 5π√2
Step-by-step explanation:
the diameter of the circle would be equal to the diagonal of the square.
Using the Pythagorean theorem:
D² = 5² + 5²
D² = 50
D = 7.0711 or 5√2
circumference = πD = 5π√2 = 22.2144
Answer:
diagonal or diameter =√(5²+5²)=5√2unit
therefore radius =5/2√2unit
circumference of circle =2πr=2×π×5/2×√2=5π√2unit
This is a similar triangle please find the missing length. (?)
Answer:
33
Step-by-step explanation:
In ΔPQR,
length of side=
77= 7×11
84= 12
Similarly, In ΔFGH
length=
36=3×12
so, the other side= 3×11= 33
Answer:
33
Step-by-step explanation:
[tex]\frac{HG}{FG} =\frac{RQ}{PQ}[/tex], insert given values
[tex]\frac{?}{36}=\frac{77}{84}[/tex], cross multiply
84*?=36*77
84*?=2772, divide both sides by 84 to get ? by itself
?=33

Triangle ABC has vertices A(0, 4), B(2, 1), and C(4, 3). Find the
coordinates of the vertices of ABC after a reflection over the
x-axis. Then graph the figure and its reflected image.
Answer:
A'= (0,-4)
B'= (2,-1)
C'= (4,-3)
Step-by-step explanation:
After you flip it over the x-axis, it would be
A'= (0,-4)
B'= (2,-1)
C'= (4,-3)

Answer:
We have to find the value of x.
We need to substitute with 3 because they measure the same.
Step-by-step explanation:
(x - 1)
x - 1 = 3
x - 1 + 1 = 3 + 1
x = 4
(x + 1)
x + 1 = 5
x + 1 - 1 = 5 - 1
x = 4
Both answers are the same which means that they are correct.

Jack bought 4 hot dogs and 3 sodas for $15.50. Mack bought 3 hot dogs and 2 sodas for $11.25. Find the cost of each.
Answer:
Hot dogs: $2.75
Sodas: $1.5
Step-by-step explanation:
Hot dogs = x
Sodas = y
4x + 3y = 15.5
3x + 2y = 11.25
First find the value of the hot dogs by canceling out y:
2(4x + 3y) = 2(15.5)
3(3x + 2y) = 3(11.25)
= 8x + 6y = 31
9x + 6y = 33.75
x = $2.75 (Minus bottom equation from the top to isolate x)
Plug in for x to get y:
3(2.75) + 2y = 11.25
2y = 11.25 - 8.25 (Isolate the y)
2y = 3
y = 3/2, or $1.5

If 12% of the air leaks out of Brian's bicycle tire every day, what percent of the air will be left after 2 days? After a week? Round your percents to 2 decimal places.
Answer:
77.44%
49.87%
Step-by-step explanation:
If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air
on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056
Air left on the second day = 88% - 10.56% = 77.44%
After a week = (100 - 12%)^7 = 49.87%

Answer:
c. infinitely many solution
Answer: C
Step-by-step explanation:
5 + -2x = 4 + -2x + 4 + x
Reorder the terms:
5 + -2x = 4 + 4 + -2x + x
Combine like terms: 4 + 4 = 8
5 + -2x = 8 + -2x + x
Combine like terms: -2x + x = -1x
5 + -2x = 8 + -1x
Solving
5 + -2x = 8 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
5 + -2x + x = 8 + -1x + x
Combine like terms: -2x + x = -1x
5 + -1x = 8 + -1x + x
Combine like terms: -1x + x = 0
5 + -1x = 8 + 0
5 + -1x = 8
Add '-5' to each side of the equation.
5 + -5 + -1x = 8 + -5
Combine like terms: 5 + -5 = 0
0 + -1x = 8 + -5
-1x = 8 + -5
Combine like terms: 8 + -5 = 3
-1x = 3
Divide each side by '-1'.
x = -3
Simplifying
x = -3
b) Here are the first four terms of another sequence.
7
11 15 19
Write an expression for the nth term of this sequence.
Answer:
[tex]a_{n}[/tex] = 4n + 3
Step-by-step explanation:
There is a common difference between consecutive terms, that is
11 - 7 = 15 - 11 = 19 - 15 = 4
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 4 , then
[tex]a_{n}[/tex] = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3
Leo has a lock box with a volume of 312 cubic inches. The box is 4 inches high and 13 inches long. What is the width of the box?
Answer:
6in
Step-by-step explanation:
Given data
Volume of the lockbox= 312 cubic inches
Height= 4in
Length= 13in
Width= ???
The expression for the volume of box is
V= L*W*H
substitute
312=13*W*4
312=52W
W= 312/52
W=6 in
Hence the width is 6in

[tex]-\frac{1}{2} *(-\frac{5}{6} )+(-\frac{1}{2} )*\frac{1}{3} \\=\frac{5}{12} -\frac{1}{6} \\=\frac{5}{12} -\frac{2}{12} \\=\frac{3}{12} \\\frac{1}{4}[/tex]
Answer:
it's 5/12 + 1/3
Step-by-step explanation:
you would multiply the -5/6 by -1/2 to get 5/12 since the negative would cancel out
so 5/12 + 1/3 would be the answer.
Also this question doesn't make any sense since you are supposed to simplify the parentheses first.
What is an equation of a circle whose center is (1,4) and diameter is 10?
Question options:
x2 − 2x + y2 − 8y = 83
x2 − 2x + y2 − 8y = 8
x2 + 2x + y2 + 8y = 8
x2 + 2x + y2 + 8y = 83
Answer:
[tex]x^{2} - 2x + y^{2} - 8y = 8[/tex]
Step-by-step explanation:
Standard form for a circle is:
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] (h, k) is the center r is the radius
[tex](x - 1)^{2} + (y - 4)^{2} = 5^{2} \\x^{2} - 2x + 1 +y^{2} - 8y + 16 = 25\\x^{2} - 2x + y^{2} - 8y = 8[/tex][tex]x^{2} - 2x + y^{2} - 8y = 8[/tex]
