What is the surface area of this square pyramid?
Answer:
336 m squared
Step-by-step explanation:
To do this we can first find the area of one face of the prism and multiply it by all the other triangular faces
(4*12)*4=192
then can find the area of the square underneath
12*12=144
then add them together
192+144=226

Airplane A is flying directly toward the airport which is 30 miles away. The pilot notices Airplane B 40 degrees to her right. Airplane B is also flying directly toward the airport. The pilot of Airplane B calculates that Airplane A is 30 degrees to his left. Based in that information, how far is Airplane B from the airport?
9514 1404 393
Answer:
38.6 mi
Step-by-step explanation:
The law of sines applies.
b/sin(B) = a/sin(A)
a = b(sin(A)/sin(B)) = (30 mi)sin(40°)/sin(30°)
a ≈ 38.6 mi
Airplane b is about 38.6 miles from the airport.

kathy walked 3/4 mile to piano lessons every day.How many miles does she walk in 4 days
Answer:
3 miles.
Step-by-step explanation:
Given that Kathy walks 3/4 mile every day.
[tex]\frac{3}{4}mile = 1 day[/tex]
Let's multiple it by 4.
[tex]\frac{3}{4} (4)[/tex]
Find common factor of both 4 to simplify, so of course 4.
[tex]\frac{3}{1} (1)[/tex]
Multiply across and the number should be 3! Hope that helped

Answer:
3) y = √10
4) x = 5√2
Step-by-step explanation:
The side ratios of an isosceles right triangle (one of the "special" right triangles) are ...
1 : 1 : √2
So, for some multiplier k, they can be made to match the sides in your triangles.
__
3) 1·k : 1·k : k√2 = √5 : √5 : y
Clearly, k = √5, so ...
y = (√5)(√2)
y = √10
__
4) k : k : k√2 = x : x : 10
k = 10/√2 = (5√2)/2
k = x = (5√2)/2

What is the area of this whole triangle?
Answer:
[tex] area = 380~cm^2 [/tex]
Step-by-step explanation:
[tex] \dfrac{a}{\sin A} = \dfrac{c}{\sin C} [/tex]
[tex] \dfrac{a}{\sin 30^\circ} = \dfrac{28}{\sin 25^\circ} [/tex]
[tex] a = \dfrac{28 \sin 30^\circ}{\sin 25^\circ} [/tex]
[tex] a = 33.13 [/tex]
A + B + C = 180
30 + B + 25 = 180
B = 125
[tex] area = \dfrac{ac \sin B}{2} [/tex]
[tex] area = \dfrac{33.12 \times 28 \sin 125^\circ}{2} [/tex]
[tex] area = 380~cm^2 [/tex]

Answer:
x = 27, y = 74
Step-by-step explanation:
Hi again :)
Since the angles of 5x + 4 and the one adjacent to x = 14 are corresponding angles, they are equal. That means that (5x + 4) + (x + 14) = 180 degrees.
5x + 4 + x + 14 = 180
6x + 18 = 180
6x = 162
x = 27
Also, the angle (5x + 4) and (2y - 9) are vertical angles, they are equal in value. We know the value of x now, so we'll substitute that in and solve for y.
5(27) + 4 = 2y - 9
135 + 4 = 2y - 9
139 = 2y - 9
148 = 2y
y = 74
As always, lmk if you have questions.
Angela bought two pairs of shoes for a total of $138$ The difference in the price of shoes was $42. How much was the more expensive pair of shoes? Use systems of equations to solve. You must use substitution to solve
Answer:
$90
Step-by-step explanation:
Variable x = Less Expensive Shoe
Variable y = More Expensive Shoe
Set up equations:
x + y = 138
x + 42 = y
The problem says to use substitution to solve, meaning we must substitute one variable for a different value. I will substitute variable y in the first equation for x + 42 as this equals y in the second equation.
x + x + 42 = 138
Combine like terms
2x + 42 = 138
Subtract both sides by 42 to isolate variable x
2x = 96
Divide both sides by 2 to isolate variable x
x = 48
Substitute variable x for 48 and solve for y. I will use the second equation for this.
48 + 42 = y
Combine like terms
90 = y
I defined y as the more expensive pair of shoes. Since the problem only asks for the price of the more expensive shoes, the answer is $90.

FIND X. PLEASE HELP............. ..........!
Answer:
x=23
Step-by-step explanation:
The steps below show the incomplete solution to find the value of x for the equation
5x − 2x − 3 = −2 + 15:
Step 1: 5x − 2x − 3 = −2 + 15
Step 2: 5x − 2x − 3 = 13
Step 3: 3x − 3 = 13
Which of these is most likely the next step?
3x = 16
3x = 10
3x = 39
3x = 3
The most likely step would be choice 1: 3x = 16 because in step 3, you should add 3 on both sides. So, 3's would cancel out on the left side and you solve for 13 + 3 = 16. Thus, the answer would be 3x - 16. Hope this helps :)
