Answer:
≈ 36.9
Step-by-step explanation:
You are given the opposite and adjacent side, leading you to use tan. However, since you're trying to find the angle measurement, you use the inverse of tan: [tex]tan^-1[/tex]
Set it up like this:
[tex]tan^-1 ( \frac{24}{32})=?[/tex]
When you solve, you get:
36.86
Round to the nearest tenth:
36.9

What is the area of this shape?
Answer:
272 ft^2
Step-by-step explanation:
The lower rectangle is 10 ft by (12+8) or 20 ft
The area is
A = l*w = 10 *20 = 200 ft^2
The upper rectangle is 8 ft by (19 -10) or 9 ft
A = l*w = 8* 9 = 72 ft^2
The total area is 200 + 72 = 272

Step-by-step explanation:
-2m - 5n = 7m - 3n
-9m - 5n = -3n
-9m = -2n
m = 2n/9
g(m)= 2n/9
-9/2m is the answer.
-2m-5n=7m-3n
-2n=9m
n=9m/-2
so -9/2m

Step-by-step explanation:
Answer:
Step-by-step explanation:
x^2 - 2x - 1 = x + 3
x^2 - 3x - 4 = 0
(x - 4)(x + 1)= 0
x - 4 = 0
x = 4
y= 4^2 - 2(4) - 1 = 16-8-1= 8-1= 7
(4, 7)
x + 1 = 0
x = -1

5. A race course is 99 meters long. There are trees
along 38 meters of the course. How long is the part
of the course without trees?
unit
Answer:
61
Step-by-step explanation:
99 minus 38
Answer:
61 meters
Step-by-step explanation:
To find this answer, you need to subtract the length with trees from the total length of the course. With this information, you get an equation that looks something like x + 38 = 99, with x being the length of the course without trees.
Subtract 38 from both sides:
x + 38 = 99
- 38 - 38
x = 99 - 38
Simplify:
x = 61

Answer:
B
Step-by-step explanation:
Let's start by converting each of these into decimal form.
[tex]\pi\approx 3.1416\\\sqrt{10}\approx 3.1623\\\dfrac{22}{7}\approx 3.1428[/tex]
Therefore, the correct order is:
[tex]3.14, \pi, \dfrac{22}{7}, \sqrt{10}[/tex]
or answer choice B. Hope this helps!
Answer: B. 3.14, π, 22/7, square root of 10
Step-by-step explanation:
To order the numbers in increasing order, first solve for each to get the numbers into their simplest forms.
Pi can be estimated to 3.1415, which is already bigger than 3.14.
Knowing this, you can eliminate choice A, which lists pi as less than 3.14.
Dividing 22 by 7 gets you ~3.142, which is greater than both pi and 3.14.
Knowing this, you can eliminate choices C and D, which list 22/7 as less than 3.14 and pi.
The correct answer choice is B.

In a school, the ratio of the number of boys to the number of girls in a school is 7 : 5 - if there are 600 students in the school, how many girls are there?
How many students does each unit represent?
Answer:
350 girls.
5 unit represents 250 girls and the 7 unit represents 350 boys
Step-by-step explanation:
Add 5+7 =12
600÷12=50
RATIO OF BOYS TO GIRLS IS 7:5 SO
50x5=250 GIRLS.
7*50=350
so 5 unit represents 250 girls and the 7 unit represents 350 boys.

What is the value of y?
Answer:
65 degrees
Step-by-step explanation:
First, solve for the unknown angle( not the y's).
the angle 130 is supplementary to that angle so we will use an equation to solve it. (supplementary means it adds up to 180 degrees)
x+130=180
-130 -130
x = 50 so, 50 is the measure of the interior angle
Now we have to use another equation to solve for y:
50+2y=180
-50 -50
2y = 130
/2 /2
y = 65
Thus, y is 65
So the right answer is 65 degree

Math problem: You are enlarging a photo on your computer screen. The photo starts at 3 centimeters wide. Each time you enlarge the photo, its width is doubled. You enlarge the photo four times. What is the final width of the photo on your screen?
Answer:
48 centimetres wide
Step-by-step explanation:
you are at 3
you enlarge it and you get 6
second enlargement you get 12
third enlargement you get 24
fourth enlargement you get 48
if you times 3 by 4 you are not doubling the width each time you enlarge the photo
so it is easier to double it each time you enlarge it

what is the distance between the y intercept of the function f(x)=3(2)^x and the y intercept of the function g(x) represented by the table below
A: 2 units
B: 3 units
C: 8 units
D: 9 units
The distance between the y-intercept of the function f(x)=3(2)ˣ and the y-intercept of the function g(x) for this case is given by: Option C: 8 units
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
What is the equation of a line passing through two given points in 2 dimensional plane?Suppose the given points are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex], then the equation of the straight line joining both two points is given by
[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]
We're given that:
[tex]f(x) = 3(2)^x[/tex]
Its y-intercept is:
[tex]y = f(0) = 3(2)^0 = 3\times 1 = 3[/tex]
Assuming y = g(x) is a linear function, from the first two points [tex](x_1, y_1) = (-5,15)[/tex] and [tex](x_2, y_2) = (-2, 3)[/tex], we get:
[tex](y - 15) = \dfrac{3 - 15}{-2 - (-5)} (x -(-5))\\\\y -15 = -\dfrac{12}{3} (x+5)\\\\y-15 = -4x - 20\\y = -4x - 5[/tex]
Checking if really y = g(x) is linear or not by evaluating it on its rest of the points:
[tex]y = g(2) = -4(2) -5 =-8-5 = -13\\\\y = g(5) = -4(5) -5 = -25[/tex]
These outputs matches with the table output, so we can take:
[tex]g(x) = -4x -5[/tex]
Its y-intercept is:
[tex]y = g(0) = -4(0) -5 = -5[/tex]
The distance between 3 and -5 on the y-axis is the absolute difference between these values of y, evaluated as:
[tex]d = |3 - (-5)| = |8| = 8[/tex] units.
Thus, the distance between the y-intercept of the function f(x)=3(2)ˣ and the y-intercept of the function g(x) for this case is given by: Option C: 8 units.

Answer:

Step-by-step explanation:
Solve the equation square root of 3x+4=4
The solution of equation for x is,
⇒ x = 4
We have to given that;
The equation is,
⇒√ (3x + 4) = 4
Now, We can simplify as;
⇒ √3x + 4 = 4
Take square both side,
⇒ 3x + 4 = 4²
⇒ 3x + 4 = 16
Subtract 4 both side,
⇒ 3x = 16 - 4
⇒ 3x = 12
Divide by 3;
⇒ x = 12/3
⇒ x = 4
Thus, The solution of equation for x is,
⇒ x = 4

Answer:
g(q) = [tex]\frac{5q}{8}[/tex]
Step-by-step explanation:
Given
- 7q + 12r = 3q - 4r
Rearrange making r the subject
Add 7q to both sides
12r = 10q - 4r ( add 4r to both sides )
16r = 10q ( divide both sides by 16 )
r = [tex]\frac{10q}{16}[/tex] = [tex]\frac{5q}{8}[/tex] , thus
g(q) = [tex]\frac{5q}{8}[/tex]
