John Travolta flew his plane last weekend. What would be the angle measure of∠x when his plane reached an altitude of 2500m?
Answer:
67°
Step-by-step explanation:
Ignore the 2500m for now.
To find angle x, we know that the sum of the degrees in a triangle is 180. We see that under the 2500m there is a square, indicating that the angle is 90 degrees.
So we can do 180-23-90 = 67.
Therefore, the angle measure of ∠x is 67°
Find the surface of the figure.
Answer:
64 square in.

A number sentence with a missing digit is shown.
12._8 > 12.5
Which two numbers could be the missing digit?
2
6
9
4
0
Answer:
6 and 9
Step-by-step explanation:
Because if 6 is substituted,
12.68 > 12.5 (correct!)And if 9 is substituted,
12.98 > 12.5 (correct!)For each pair of points, find the slope of the line that passes through the points.
(5, 4) and (0:1)
(3,7) and (-2,2)
Use the slope formula:-
[tex]\displaystyle\frac{y2-y1}{x2-x1}[/tex]
[tex]\displaystyle\frac{1-4}{0-5}=\frac{-3}{-5} =\frac{3}{5}[/tex]
Second pair:-
[tex]\displaystyle\frac{2-7}{-2-3} =\frac{-5}{-5} =1[/tex]
notes:-If we multiply/divide a negative by a negative, we get a positive. :)

Step-by-step explanation:
Which of the following equations is CORRECT?
A. (a + b) (a – b) = a 2 + b 2
C. (a + b) (a – b) = a 2 + ab + ab + b 2
B. (a + b) (a – b) = a 2 − b 2
D. (a + b) (a – b) = a 2 − ab − ab − b 2
Answer:
Option C, the second one. (B and C are switched)
Step-by-step explanation:
a * a = a2
a * b = +ab
⬇️
2ab
⬆️
b * a = +ba or +ab
Two b's make b2 and don't worry, even with the negative sign it is a b2.
Solve for Y. Will mark branliest please help!
Answer:
y = 2 v2, 2 square root 2
Step-by-step explanation:
since it's a right triangle with a 45°, that means the other angle is also 45°
which makes both sides the same
Pythagoras
4^2 = y^2 + y^2
16 = 2 y^2
16/2 = y^2
8 = y ^2
v8 = y
2 v2 = y
note: (v = square root)
Answer:
[tex]2\sqrt{2[/tex]
Step-by-step explanation:
The ratios of a 45 - 45 - 90 triangle is [tex]1:1:\sqrt{2}[/tex]
To get 4 for the hypotenuse, you need to mulitpy [tex]\sqrt{2}[/tex] by [tex]\sqrt{8}[/tex].
[tex]\sqrt{2}[/tex] x [tex]\sqrt{8}[/tex] = [tex]\sqrt{16}[/tex]
Simplify.
[tex]\sqrt{16} = 4[/tex]
If you simplify the [tex]\sqrt{8}[/tex], it equals [tex]2\sqrt{2}[/tex].
Since the ratio is [tex]1:1:\sqrt{2}[/tex]
The sides will be [tex]2\sqrt{2}:2\sqrt{2}:4[/tex]

Al vender una computadora, un vendedor descuenta el 15%, y aun así gana el 35%, del costo. ¿qué %del costo es el precio de venta?
Veremos que el precio de venta es el 158% del costo.
¿Que porcentaje del costo es el precio de venta?
Sabemos que con el descuento del 15%, el vendedor gana 35% del costo.
Es decir, si el costo es C, entonces el precio al que se vende la computadora es:
P' = (1 + 0.35)*C = 1.35*C
Pero, esto es con un 15% de descuento. Entonces si el precio de venta es P, tendremos:
P' = (1 - 0.15)*P = (0.85)*P
Reemplazando esto arriba tenemos:
(0.85)*P = 1.35*C
Resolviendo para P:
P = 1.35*C/0.85 = 1.58*C
Para obtener el porcentaje, multiplicamos el coeficiente por 100%.
1.58*100% = 158%.
Es decir, el precio de venta es el 158% del costo.

Which expression is equivalent to i 233?
1
–1
i
–i
Step-by-step explanation:
i¹ = i
i² = i×i = -1
i³ = -1 × i = -i
i⁴ = -i×i = - -1 = 1
i⁵ = 1×i = i
...
so, when the exponent of i modulo 4 (the remainder when dividing by 4) = 0, then the result is 1.
= 1, then the result is i
= 2, then the result is -1
= 3, then the result is -i
233 modulo 4 = 1 (233/4 = 58, remainder 1).
so, the result is i (the third answer option).

At his schools book fair, Henry brings $10.00. He purchases a book for $8.50, plus a 6% sales tax. How much money in change will Henry receive?
Answer:
$0.99 in change
Explanation:
To apply the sales tax, you have to multiply:
8.50*1.06=9.01
This means that, with tax, the book will cost $9.01. If he gave them $10, he would get 99 cents back because 10-9.01 is 0.99.
