Answer:
B = 58.9
Step-by-step explanation:
We are given that a triangle ABC has two side lengths of 28 ft. and 24 ft. with angle C measuring 91°. We are to find the measure of angle B.
AB = 28 ft
AC = 24 ft
For this, we will use the sine formula:
[tex]\frac{sin B}{24} = \frac{sin91}{28}[/tex]
[tex]sin B = \frac{sin91 \times 24}{28}[/tex]
[tex] sin B = 0 . 8 5 7 [/tex]
[tex] B = sin' 0 . 8 5 7 [/tex]
B = 58.9

why are units of measure important when solving real-word problems?
In physics, we always measure quantities and compare them with a standard. That standard defines a unit of the quantity. Suppose you want to measure the length of a car, so you use a meter stick, which is the standard for measuring distances. Then, why are units of measure important when solving real-world problems? Well, because when solving problems that involve equations, they need to be dimensionally consistent, but what does it mean? it means that you can't add two terms having different units. For instance, you can't add apples with tables!
Identify the vertex and the y-intercept of the graph of the function,

[tex]\bf \stackrel{\textit{the y-intercept occurs when x =0}~\hfill }{y=0.25(0+5)^2\implies y=0.25(5)^2}\implies y=6.25~\hfill \stackrel{\textit{y-intercept}}{(0, 6.25)}[/tex]
To identify the vertex and the y-intercept for the function \( y = 0.25(x + 5)^2 \), we will use our knowledge of quadratic functions and their properties.
Vertex:
The given function is in the form of \( y = a(x - h)^2 + k \), where (h, k) is the vertex of the parabola. This form is commonly referred to as the vertex form.
For the given function, \( y = 0.25(x + 5)^2 \), we can see that it is equivalent to \( y = 0.25(x - (-5))^2 + 0 \), indicating that the vertex (h, k) is at (-5, 0). This means the parabola opens upwards (because the coefficient of \( (x + 5)^2 \) is positive) and has its vertex point at x = -5 and y = 0.
Y-intercept:
The y-intercept of a function is found by evaluating the function when x = 0.
So we'll substitute x = 0 into the function to find the y-coordinate of the y-intercept:
\( y = 0.25(0 + 5)^2 \)
Now, we'll calculate the value inside the parentheses:
\( 0 + 5 = 5 \)
Then, we raise it to the power of 2:
\( 5^2 = 25 \)
Finally, we multiply by 0.25:
\( y = 0.25 \times 25 = 6.25 \)
Therefore, the y-intercept where the graph crosses the y-axis is at the point (0, 6.25), where the x-coordinate is 0 and the y-coordinate is the value we just calculated, 6.25.
In summary, the vertex of the function \( y = 0.25(x + 5)^2 \) is (-5, 0), and the y-intercept is at (0, 6.25).
Owen has enough materials to build up to 10 birdhouses in shop class. Each birdhouse needs 12 square feet of wood. The function W(b) = 12b represents the total amount of wood that Owen would need to build b birdhouses. What domain and range are reasonable for the function?
A: D: 10 ≤ b ≤ 12
R: 0 ≤ W(b) ≤ 120
B: D: 0 ≤ b ≤ 10
R: 12 ≤ W(b) ≤ 120
C: D: 0 ≤ b ≤ 120
R: 0 ≤ W(b) ≤ 10
D: D: 0 ≤ b ≤ 10
R: 0 ≤ W(b) ≤ 120
Answer:
120
Step-by-step explanation:
A: D: 10 ≤ b ≤ 12
R: 0 ≤ W(b) ≤ 120
B: D: 0 ≤ b ≤ 10
R: 12 ≤ W(b) ≤ 120
C: D: 0 ≤ b ≤ 120
R: 0 ≤ W(b) ≤ 10
D: D: 0 ≤ b ≤ 10
R: 0 ≤ W(b) ≤ 120
W(b) = 12b.
he has enough to build 10 birdhouses, he doesn't have for more than that, he can either build no birdhouses or build 10 birdhouses, since "b" is the independent variable and thus the domain will come from it, what values can "b" safely take? "b" can be either 0 or more than 0 but nor more than 10, because Owen doesn't have enough for more than that, 0 ≤ b ≤ 10.
let's say owen chooses to build 0 birdhouses, then W(0) = 12(0) => W(0) = 0.
let's say owen chooses to build 10 birdhouses, then W(10) = 12(10) => W(10) = 120.
so the amount of wood needed for those birdhouses, namely the range, can be either 0, if he chooses to build none, or 120 if he chooses to build 10, 0 ≤ W(b) ≤ 120.
At the beginning of year 1, Josie invests $400 at an annual compound interest
rate of 5%. She makes no deposits to or withdrawals from the account.
Which explicit formula can be used to find the account's balance at the
beginning of year 3?
The balance in Josie's account at the beginning of year 3, with a $400 investment at 5% annual compound interest, can be calculated using the compound interest formula A = P(1 + r)^n, which results in $441.
Explanation:The explicit formula to find the account's balance at the beginning of year 3 for Josie's investment with an annual compound interest rate can be determined using the compound interest formula:
A = P(1 + r)^n
Where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of years the money is invested.In Josie's case, she invested $400 at a 5% annual interest rate for 2 years. The formula will look like this:
A = 400(1 + 0.05)^2
Now, calculate the amount:
A = 400(1 + 0.05)^2
A = 400(1.05)^2
A = 400(1.1025)
A = $441
Hence, the balance in Josie's account at the beginning of year 3 would be $441.
Yumi wants to make 12 cups of party mix using candies and nuts. Her budget requires the party mix to cost her $1.29 per cup. The candies are $2.49 per cup, and the nuts are $0.69 per cup. How many cups of candies and how many cups of nuts should she use?
Answer:
4 cups of candies and 8 cups of nuts
Step-by-step explanation:
Cost per cup = $1.29
Total number of cups = 12
Total cost of cups = 12 x $1.29
= $15.48
Cost of candies = $2.49 per cup
Total number of candies = x
Cost of nuts = $0.69 per cup
Total number of nuts = y
Equations :
x + y = 12 (because total cups of nuts and candies will be equal to 12)
2.49x + 0.69y = 15.48 (Total cost of the 12 cups should be 15.48)
Step 1 : Find x in terms of y
x = 12 - y
Step 2 : substitute x in terms of y from step 1 in the second equation
2.49x + 0.69y = 15.48
2.49 ( 12 - y) + 0.69y = 15.48
29.88 - 2.49y + 0.69y = 15.48
-1.8y = -14.4
y = 14.4/1.8
y = 8
Step 3 : Find x
x + y = 12
x = 12 - y
x = 12- 8
x = 4
Yumi should use 4 cups of candies and 8 cups of nuts.
!!
The number of cups of candies and nuts, Yumi should use is 4 and 8 cups respectively.
Let the candies be C.Let the nuts be N.Given the following data:
Cost of candies per cup = $2.49Cost of nuts per cup = $0.69Translating the word problem into an algebraic expression, we have;
For total number of cups:
[tex]C + N = 12[/tex] .....equation 1
For cost of candies and nuts:
[tex]2.49C + 0.69N = 1.29(12)\\\\2.49C + 0.69N = 15.48[/tex].....equation 2
From equation1:
[tex]C = 12 - N[/tex] ....equation 3
Substituting eqn 3 into eqn 1, we have:
[tex]2.49(12 - N) + 0.69N = 15.48\\\\29.88 - 2.49N + 0.69N = 15.48\\\\1.8N = 29.88 - 15.48\\\\1.8N = 14.4\\\\N = \frac{14.4}{1.8}[/tex]
Number of nuts, N = 8 cups
For candies:
[tex]C = 12 - N\\\\C = 12 - 8[/tex]
Number of candies, N = 4 cups

How long will it take to earn $1800 in interest if $6000 is invested at a 6% annual interest rate?
Answer:
It will take 5 years.
Step-by-step explanation:
Let's find how long it will take, but first let's understand the equation.
For simple interest, we use the equation:
T=(1/R)*(((A+B)/B)-1) where,
A= interest amount
B=invested money
R=interest rate (in decimal form)
T=time
Because we want to earn $1800 in interest, then A=1800.
Because we invested $6000, then B=6000.
Because we are investing under an interest rate of 6%, then R=0.06.
'How long will it take' means that T= not given, but its value is in 'years', since an annual rate was given.
Using the equation for simple interest we write:
T=(1/0.06)*(((1800+6000)/6000)-1), the solution is then:
T=5; remember, because is an annual rate, T solution means 5 years.

Second equation:
[tex]-2x+3y=4[/tex]
Third equation:
[tex]4x+5y+4z=-2[/tex]

If f(9)=7, then the point ___________ is on the graph of f.
Answer:
(9,7)
Step-by-step explanation:
F(a)=b means the point (a,b) is on the graph of F
The point that is on the graph of the function f, given f(9)=7, is (9, 7). This results because 9 is the input (x-coordinate) and 7 is the output (y-coordinate) of the function.
Explanation:In mathematics, particularly in graphing functions, each point on the graph of a function f is represented by an ordered pair: the input (x-coordinate) and the output (y-coordinate). When you are given that f(9)=7, this essentially means that when the input is 9, the output is 7. Therefore, the point that is on the graph of the function f is (9, 7).

Solve to find the value for x in the linear equation: 3(−4x + 5) = 12.
Final answer:
The linear equation is solved by distributing the number outside the parentheses, combining like terms, and then isolating the variable x. The final answer is x = 1/4.
Explanation:
To solve the linear equation 3(−4x + 5) = 12, let's follow the standard steps for solving a linear equation.
Distribute the 3 to both terms inside the parentheses: 3 × (−4x) + 3 × 5 = 12, which simplifies to −12x + 15 = 12.
Subtract 15 from both sides of the equation to get the x term by itself: −12x + 15 − 15 = 12 − 15, which simplifies to −12x = −3.
Finally, divide both sides of the equation by −12 to solve for x: −12x / −12 = −3 / −12, which simplifies to x = 1/4.
By following these steps, we've found that the value that satisfies the equation is x = 1/4.
Final answer:
To solve the equation 3(−4x + 5) = 12, distribute the 3, subtract 15 from both sides, and then divide by −12, yielding the solution x = 1/4 or 0.25.
Explanation:
To solve the linear equation 3(−4x + 5) = 12, we'll start by expanding the equation and then isolating x.
First, distribute the 3 into the parentheses: 3 × (−4x) + 3 × 5 = 12, which simplifies to −12x + 15 = 12.Next, subtract 15 from both sides of the equation to get −12x = 12 − 15, which simplifies to −12x = −3.Now, divide both sides by −12 to solve for x: x = −3 / −12, which simplifies to x = 1/4 or 0.25.Therefore, the solution to the equation 3(−4x + 5) = 12 is x = 0.25.

Answer:
k = 29
Step-by-step explanation:
(5k -3) + (9+k) = 180
5k-3+9+k = 180
6k + 6 = 180
6k = 180 - 6 = 174
k = 29
The value of k is:
k = 29
Step-by-step explanation:We know that when two angles lie on a straight line then the sum of the two angles is equal to 180 degree.
Here we have two angles on a straight line as:
first angle = (5k-3)°
and second angle= (9+k)°
Hence, we have:
(5k-3)°+(9+k)°=180°
i.e.
5k-3+9+k=180
on combining the like terms on the left hand side of the equation we have:
5k+k+9-3=180
6k+6=180
6k=180-6
6k=174
i.e.
k=174/6
i.e.

[tex]\displaystyle 1- \frac{1}{5} - x = \frac{2}{3}[/tex].
Add [tex]x[/tex] to both sides of this equation:
[tex]\displaystyle 1 - \frac{1}{5} = \frac{2}{3} +x[/tex]
Substract [tex]\displaystyle \frac{2}{3}[/tex] from both sides:
[tex]\displaystyle 1 - \frac{1}{5} - \frac{2}{3} = x[/tex].
Convert the denominator of all three numbers on the left-hand side to [tex]3 \times 5 = 15[/tex]
[tex]\displaystyle \frac{15}{15} - \frac{3}{15} - \frac{10}{15} = x[/tex].
[tex]\displaystyle x = \frac{2}{15}[/tex].
In other words, Catherine's sister ate [tex]\displaystyle \frac{2}{15}[/tex] gallons of the ice cream.
To solve this, we need to add the 1/5 of the ice cream to the 2/3 left of ice cream to find out how much her sister ate.
First, we need a common denominator. We can multiply 3 by 5 to get a common denominator easiest, since they are both multiples of it.
3*5=15
Now multiply the numerators by the amount the denominators were multiplied by.
1*3=3 so 3/15
2*5=10 so 10/15
Now, add them together.
10/15+3/15= 13/15.
Finally, subtract that amount from the original full amount of ice cream (15/15) to get the amount her sister ate, since that is the only unknown value left.
15/15-13/15=2/15.
Because 15 isn’t divisible by 2, we can’t simplify this fraction anymore.
Her sister ate 2/15 of a gallon of ice cream.
Hope this helps!
Which module represents that equation?
Answer:
the one on the bottom left
Step-by-step explanation:
Note that the cube on the bottom left is composed of
4 × 4 × 4 = 64 ← unit cubes
Thus the volume of the cube = 64 units³
The volume of a cube = s³ ← where s is the side length
Thus s³ = 64
To find s given the volume take the cube root of both sides, that is
s = [tex]\sqrt[3]{64}[/tex] = 4
