Answer:
Step-by-step explanation:
Ok so for question one we use the Pythagorean theorem, which is a^2+b^2=c^2
a is the shortest leg, b is the leg that is not the hypotenuse. and c is the hypotenuse which is the opposite leg to the right angle.
Question 1: a=9,b=12,c=x
(9)^2+(12)^2=(x)^2
81+144=(x)^2
225=(x)^2
x=15
Question 2: a=10,b=24,c=x
(10)^2+(24)^2=(x)^2
100+576=(x)^2
676=(x)^2
x=26
Question 3: a=3,b=7,c=x
(3)^2+(7)^2=(x)^2
9+49=(x)^2
58=(x)^2
x=root58, or 7.615773
Question 4: a=6,b=x, c=10
(6)^2+(x)^2=(10)^2
36+(x)^2=100
Subtract 36 from both sides
(x)^2=64
x=8
Question 5: a=6,b=x, c=24
(6)^2+(x)^2=(24)^2
36+(x)^2=576
Subtract 36 from both sides
(x)^2=540
x=6root15, or 23.2379
Question 6: a=1, b=1, c=x
(1)^2+(1)^2=(x)^2
1+1=(x)^2
2=(x)^2
x=root2, or 1.414213562
Question 7: a=8, b=x, c=21
(8)^2+(x)^2=(21)^2
64+(x)^2=441
Subtract 64 from both sides
(x)^2=377
x=root377, or 19.41648784
Question 8: a=24, b=x, c=30
(24)^2+(x)^2=(30)^2
576+(x)^2=900
Subtract 576 from both sides
(x)^2=324
x=18
Question 9: a=5,b=9, c=x
(5)^2+(9)^2=(x)^2
25+81=(x)^2
106=(x)^2
x=root106, or 10.29563014
Question 9 Part B: a=3, b=5, c=y
(3)^2+(5)^2=(y)^2
9+25=(y)^2
34=(y)^2
root34, or 5.830951895=y

what is the median of this data set?
16,21,28,30,34,45,58,60
Answers
Answer:
32
Step-by-step explanation:
the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.
this is what it would look like.
16, 21, 28, 30, 34, 45, 58, 60
(basically how it is in the problem lol)
since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30 and 34.
you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)
(30+34)/2
we divide by two because there are two numbers.
(30+34)/2
(64)/2

Special right triangles how do you solve them
Answers
The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.
In a 45°-45°-90° triangle, the legs and hypotenuse occur in a ratio of 1 : √2. This means
(1) x = 48 √2
(2) 88 = √2 x → x = 88 / √2 = 44 √2
You could also set up trigonometric equations to solve for x in each case:
(1) cos(45°) = 48 / x → x = 48 / cos(45°) = 48 / (1 / √2) = 48 √2
(2) cos(45°) = x / 88 → x = 88 cos(45°) = 88 (1 / √2) = 44 √2

O número -3 é a raíz da equação x² - 7x - 2c = 0. Nessas condições, determine o valor do coeficiente c: A) 7 B) -2 C) -3 D) 15 E) NDA
Answers
Responder:
c = 15
Explicação passo a passo:
se -3 é a solução para a expressão x² - 7x - 2c = 0, para obter c, vamos substituir x = -3 na equação (uma vez que é uma raiz)
x² - 7x - 2c = 0
(-3) ² - 7 (-3) - 2c = 0
9 + 21 - 2c = 0
30 - 2c = 0
30 = 2c
Trocar
2c = 30
c = 30/2
c = 15
Portanto, o valor de c é 15
If y varies jointly as x and z and y = 4 when x = 2 and z = 3, what is y when x = -6 and z = 2?
Answers
Answer:
Step-by-step explanation:
Y = kxz
Putting values of y x and z in the equation
4 = k(2)(3)
4 = k6
2/3 = k
Now finding y when x = - 6 and z = 2
Y = kxz
= 2/3(-6)(2)
= - 8

christen has to run around the rectangle soccer field during practice. The soccer field measures 60 meters long by 45 meters wide. How far did christen run?
Answers
Answer:
210 m
Step-by-step explanation:
Perimeter is the distance around the outside of a two-dimensional shape.
Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
Christen ran around the soccer field, so she ran around the perimeter.
We can find the perimeter by adding all of the side lengths.
Perimeter=60 m+45 m+60 m+45 m
Christen ran 210m.

tell whether a triangle can have the given angle measures:
47°, 109°, 23°
Answers
Explanation: All the angles of a triangle has to add up to 180. The angles you provided adds up to 179, which does not equal 180. That means it can’t be a triangle.

47 + 109 + 23 = 179
But the angle sum of a triangle is 180.
Pepe compró una caja de chocolates en $5.950, incluido el 19% de IVA. ¿Cuál es el precio de la caja de chocolates sin el IVA?
Answers
Answer:
$4819.5
Step-by-step explanation:
Pepe bought a box of chocolates for $ 5,950, including 19% VAT. What is the price of the box of chocolates without VAT?
The price of chocolates = $5,950
VAT = 19%
We need to find the price of the box of chocolates without VAT.
VAT is applied on the Cost price of the object.
Price = $5,950 - 19% of $5,950
[tex]=5950- 5950\times \dfrac{19}{100}\\\\=\$4819.5[/tex]
So, the price of the box without VAT is equal to $4819.5.

Answers
Answer:
Step-by-step explanation:
Let d be the diameter of the wheel.

πd = 1.413
d = 1.413/π = 0.45 m

Which transformations can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4)? a 180degree rotation about the origin a 90degree counterclockwise rotation about the origin and a translation down 4 units a 90degree clockwise rotation about the origin and a reflection over the y-axis a reflection over the y-axis and then a 90degree clockwise rotation about the origin
Answers
The transformations that can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4) is C. a 90 clockwise rotation about the origin and a reflection over the y-axis
What is a Transformation?This refers to the mathematical process where one figure or expression is changed from one form to another that has or contains a similar value.
Given the pair of points (x, y) in the original image, it has been transformed to (-y, -x).
If we allow ABC to be first transformed onto A"B"C" by a 90° clockwise rotation, this would result in:
B(4, 1) being mapped onto B''(1, -4).
Therefore, the rule mapping ABC to A"B"C" is (x, y)→(y, -x)
With this, we can conclude that the transformation that maps (y, -x) to (-y, -x) is a reflection with respect to the y-axis
Option C is the correct transformation.

What is the total area of each garden bed has a length of 4 feet Amelia
Answers
Answer:
48 ft^2.
Step-by-step explanation:
In this case, our formula is known as 3s^2 which can be written out as 3 x s x s or 3(s x s). S is the variable to represent our length and width because the formula for finding the area is l x w which can be written out as length x width. If the total area of each garden bed has a length of 4 feet, our equation would be 3(4 x 4) or 3 x 4 x 4 or 3(4)^2. 4 x 4 or 4^2 is 16. If we multiply 16 by 3, the answer would be 48. That is why the total area of each garden bed would be 48 ft^2.
