Answer:
x + 37 = 90
Step-by-step explanation:
Since complementary angles add up to 90 degrees, we would need to add 37 and x to equal 90 degrees. Therefore, x + 37 equals 90 degrees. As for solving, subtract 37 from both sides and you are left with x = 53.

Wanda has three times more shirts than her brother, Will. The equation a = 3b, where a represents the number of shirts Wanda has, and b represents the number of shirts Will has, shows this relationship. If Wanda has 24 shirts, how many shirts does Will have?
Answer:
8 shirts
Step-by-step explanation:
Given the equation a = 3b, where
a = the number of shirts Wanda has
b = the number of shirts Wanda's brother (Will) has
Hence if Wanda has 24 shirts then
24 = 3b
Divide both sides by 3
24/3 = b
b = 8 shirts
Will has 8 shirts.
Answer:
8 shirts

A student used the proportion n/100 = 5/26 to find 5% of 26. What did the student do wrong?
Given:
A student used the proportion [tex]\dfrac{n}{100}=\dfrac{5}{26}[/tex] to find 5% of 26.
To find:
The student's mistake.
Solution:
Let 5% of 26 be n. Then,
[tex]n=\dfrac{5}{100}\times 26[/tex]
On dividing both sides by 26, we get
[tex]\dfrac{n}{26}=\dfrac{5}{100}[/tex]
So, the proportion used by the student was incorrect. The denominators of the proportion are interchanged.

A right triangle with vertices labeled as A, B, and C. Side C B is the base, and the top vertex is A. Side A B contains a midpoint D. A line segment drawn from C to D bisects angle A C B into two parts labeled as A C D and B C D. Angles A C D and B C D are marked with single arc. Side A C is labeled as 3. Base C B is labeled as 4. Segment A D is labeled as 2.25. Segment B D is labeled x.
Use triangle bisect or theorem.
Set up proportion:
X/ 2.25 = 4/3
Cross multiply:
3x = (4 x 2.25)
3x = 9
Divide both sides by 3:

Which equation represents this situation? y = 1.25x ) Which graph represents the situation?
The second graph represents the situation y=1.25x which has slope 1.25.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is y= 1.25x
Slope is 1.25
Now let us plug in (1, 1.25) in the equation
1.25=1.25(1)
Hence, the second graph represents the situation y=1.25x which has slope 1.25.

The function c ( x ) = 63 ⋅ ( 1.03 ) x models the cost in dollars, c , of 1 ounce of a certain chemical used in a laboratory. x represents the number of years since 1990.
Does the cost of the chemical increase or decrease with time?
Group of answer choices
Increase
Decrease
9514 1404 393
Answer:
increase
Step-by-step explanation:
Your cost function appears to be an exponential function of the form ...
c(x) = (initial cost)·(growth factor)^x
When the growth factor (1.03) is greater than 1, it means the exponential function is increasing with x (time).
The cost function increases with time.

Attorney B charges $150 for the initial meeting and
$175 per hour.
Write an equation in slope-intercept form.
Answer:
y = 175x + 150
Step-by-step explanation:
If it costs 175 per hour, that would be 175x (where x is the number of hours) and there is an initial fee of 150, so you add 150.
This means the equation is y = 175x + 150

You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases by about 35% each hour. What level of aspirin (mg) will be in your bloodstream in 4 hours. NEED ANSWER URGENT!!!
Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.
Step-by-step explanation:
If the amount is decreasing by r%, then the final amount is given by :-
[tex]A=P(1-r)^t[/tex]
, where P = initial value , t= time
Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours
The level of aspirin (mg) will be in your bloodstream in 4 hours = [tex]200(1-0.35)^4[/tex]
[tex]=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg[/tex]
Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.
The pyramid pictured below has a total surface area of 156 feet squared find the missing measurement
10 points is all i have
Answer:
maybe 36
Step-by-step explanation:
but can u help me What is the surface area of a square-based pyramid with a base length of 5 m and a slant height of 3 m?
Enter your answer in the box.
The missing measurement is 10 feet.
What is pyramid?A three-dimensional shape is a pyramid. A pyramid's flat triangular faces unite at a common point known as the apex and have a polygonal base. The bases are joined to the peak to create a pyramid. The lateral face is a triangle face formed by the connection of each edge of the base to the apex.
To find the surface area of the pyramid, we can use the following formula,
A = (½)Pl + B.
Where P is the base perimeter, l is the slant height and B is the base area.
Here, the base is square-shaped.
Now, let the slant height be x.
A = (1/2)(4 × 6) (x) + (6)²
156 = 12x + 36
12x = 156 - 36
12x = 120
x = 10 feet.
Therefore, the required height is 10 feet.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
[tex]6^5[/tex] x [tex]5^{-3}[/tex] = 6²
Now,
Simplifying the expression.
= [tex]6^5 \times 5^{-3}[/tex]
= [tex]\frac{6^5}{5^3}[/tex]
We see that,
6² is when we add the exponents even if the base is not the same.
We can not add the exponent if the base is not the same.
Thus,
Eli is incorrect because he added the exponents even though the bases are not the same.

What is the rule that describes a reflection across the line y = x?
rx = y(x, y) →
Answer:

Step-by-step explanation:
GH=5 5; <H = 90
1. The mapping of the vertices of ΔDEF will be;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)
2. The rule of the reflection across the line y = x is;
[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]
What is Refection?
Reflection is a type of transformation that flip a shape in mirror line, so that each point is the same distance from the mirror line as its reflected point.
Given that;
The coordinates are,
D = (2, –4)
E = (1, –1)
F = (5, 1)
Now,
By the given image,
The mapping of the vertices of ΔDEF is;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)
And, The rule of the reflection across the line y = x is;
[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]
Because in the image its shows the line of reflection.
Therefore,
1. The mapping of the vertices of ΔDEF will be;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)

Answer: The answer is C) J' (3,-1), K' (1,-4)
Step-by-step explanation: First, you need to find the location of J, which is located in Quadrant III. You go left 3, and go down 1, making the coordinates of J (-3,-1). Next, you need to find the location of K, which is also located in (-1, -4).
So, the question asks, "What are the coordinates of J' and K' after JK is reflected across the y-axis?"-- Well, first, which line is the x-axis, and which line is the y-axis?
The x-axis is the line that is horizontal(Across) while the y-axis is the line that is vertical( Up and Down).
So you bring J and Ks coordinated over the y-axis to Quadrant IV(4). You already know their original coordinates, so you place the as you would in the picture above, except that the line would be reflected.
