Given h(x)
-2x + 5, solve for x when h(x) = 3.
Answers
Answer:
x = 1
Step-by-step explanation:
h(x) = -2x + 5 and h(x) = 3
which means -2x + 5 = 3
solve for x
-2x + 5 = 3
-5 -5
-2x = -2
-2 -2
x = 1
-2x=3-5
-2x=-2
x= -2/-2
x= 2/2

A family spends 1/10 of it's annual income for housing 1/4 for food and clothing 1/5 for general expenses and 2/15 for entertainment what fractional part of their income is spent on these items altogether.
Answers
Answer:
The family spends 41/60 of its income on these items altogether.
Step-by-step explanation:
Given that a family spends 1/10 of it's annual income for housing, 1/4 for food and clothing, 1/5 for general expenses and 2/15 for entertainment, to determine what fractional part of their income is spent on these items altogether the following calculation must be performed:
10, 4, 5, and 15 have a common least multiple at 60.
1/10 = 6/60
1/4 = 15/60
1/5 = 12/60
2/15 = 8/60
6 + 15 + 12 + 8 = 41
Therefore, the family spends 41/60 of its income on these items altogether.
Find the area of each figure. Round to the nearest tenth if necessary
Answers
Answer:
b. 869.6 ft²
Step-by-step explanation:
The figure is composed of an equilateral triangle and a trapezoid
Therefore,
Area of the figure = area of the triangle + area of the trapezoid
✔️Area of triangle = ½*a*b*Sin C
Where
a = 22 ft
b = 22 ft
C = 60° (mall angles of an equilateral triangle measures 60°)
Area = ½*22*22*Sin 60°
Area = 209.58 ft²
✔️Area of trapezoid = ½(a + b)h
a = 22 ft
b = 38 ft
h = 22 ft
Area = ½(22 + 38)22
Area = ½(60)22
Area = 960 ft²
✔️Area of the figure = 209.58 + 660 = 869.58 ≈ 869.6 ft²

Step-by-step explanation:
So he spends 25% of his 30 hours on games so 30x0.25=7.5 since 25% is equal to 0.25. He also spends 5% of the 30 hours on research. 30x0.05=1.5. 7.5-1.5=6
If 18 is 45% what is 100%
need help ASAP any random answers just for points will be reported
Answers
Answer: 45
Step-by-step explanation:
Solution for What is 45 percent of 100:
45 percent * 100 =
(45:100)* 100 =
(45* 100):100 =
4500:100 = 45
Now we have: 45 percent of 100 = 45
Question: What is 45 percent of 100?
Percentage solution with steps:
Step 1: Our output value is 100.
Step 2: We represent the unknown value with $x$x.
Step 3: From step 1 above,$100=100\%$100=100%.
Step 4: Similarly, $x=45\%$x=45%.
Step 5: This results in a pair of simple equations:
$100=100\%(1)$100=100%(1).
$x=45\%(2)$x=45%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{100}{x}=\frac{100\%}{45\%}$
100
x=
100%
45%
Step 7: Again, the reciprocal of both sides gives 45
$\frac{x}{100}=\frac{45}{100}$
x
100=
45
100
$\Rightarrow x=45$⇒x=45
Therefore, $45\%$45% of $100$100 is $45$
Answer:
40
Step-by-step explanation:
I like to find common factors.
45% and 18 are both divisible by 9.
so
45% ÷ 9 = 5%
18 ÷ 9 = 2
2 is equal to 5%
100% ÷ 5% = 20
so
20 × 2 = 40
100% = 40.

Explanation:
The geometric mean can be represented by [tex] \sqrt[n]{x_{1} • x_{2} • x_{3} • .. x_{n}} [/tex].
Which is the mean of the product of n numbers, used to find the average of a geometric progression.
Don't get confused by geometric mean, it is only asking you about the next numbers in the geometric sequence given the first and sixth term.
The explicit rule for a geometric sequence can be modeled by:
[tex] a_{n} = a_{1} • r^{n-1} [/tex]
Where [tex] a_{n} [/tex] is the nth term, [tex] a_{1} [/tex] is the first term in the sequence, n is the term number, and r is the common ratio.
Since we already know the first term, [tex] a_{1} [/tex] will simply be 32.
Since we know it's geometric, there will be an exponential relationship, which means that we will use the geometric mean to find the common ratio.
There are 6 total terms, r is raised to the n – 1 so 6 – 1 = 5, and that will be the degree of this root.
[tex] \sqrt[5]{\frac{a_{6}}{a_{1}}} [/tex] =
[tex] \sqrt[5]{\frac{1}{32}} [/tex] =
[tex] \frac{1}{2} [/tex].
Therefore: [tex] r = \frac{1}{2} [/tex].
Using all the information we have, we can find the explicit rule:
[tex] a_{n} = a_{1} • r^{n-1} [/tex]
[tex] a_{1} [/tex] = 32[tex] r = \frac{1}{2} [/tex][tex] a_{n} = a_{1} • r^{n-1} [/tex] →
[tex] \boxed{a_{n} = 32 • (\frac{1}{2})^{n-1}}[/tex]
________________________________
We can test that this works by substituting the number location of the term you want to find.
For instance:
[tex] a_{1} = 32 • (\frac{1}{2})^{1-1} [/tex]
[tex] a_{1} = 32 • (\frac{1}{2})^{0} [/tex]
[tex] a_{1} = 32 • 1[/tex]
[tex] a_{1} = 32 [/tex]
[tex] a_{6} = 32 • (\frac{1}{2})^{6-1} [/tex]
[tex] a_{6} = 32 • (\frac{1}{2})^{5} [/tex]
[tex] a_{6} = 32 • \frac{1}{32} [/tex]
[tex] a_{6} = 1 [/tex]
