Adele rides her bike 28 miles in 3.5 hours. How far has Adele traveled on her bike if she rides for 8 hours?
Answer:
64 miles
Step-by-step explanation:
if you divide 28 by 3.5, this gives you the number of miles per hour, I got 8. Multiply that by 8 because that is the number of hours we are looking for and you get 64. That is the answer.
What is the slope of the line that passes through the points (−6,−4) and (-12, -4) ?
Answer:

Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
-4-(-4)/-12-(-6)
0/-6
Since the numerator is 0, the slope is 0.

Por un tubo de 2.5 cm de diámetro fluye agua con una repidez de 20 cm/s ¿Cuál es el valor del flujo y el gasto del agua?
Answer:
El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.
Step-by-step explanation:
El gasto del agua ([tex]Q[/tex]), medido en centímetros cúbicos por segundo, es el flujo que pasa a través del tubo. La ecuación para determinar el gasto es:
[tex]Q = \frac{\pi}{4}\cdot D^{2}\cdot v[/tex] (1)
Donde:
[tex]D[/tex] - Diámetro del tubo, medido en centímetros.
[tex]v[/tex] - Velocidad del flujo, medida en centímetros por segundo.
Si sabemos que [tex]D = 2.5\,cm[/tex] y [tex]v = 20\,\frac{cm}{s}[/tex], entonces el flujo y gasto del agua es:
[tex]Q = \frac{\pi}{4}\cdot (2.5\,cm)^{2}\cdot \left(20\,\frac{cm}{s} \right)[/tex]
[tex]Q \approx 98.175\,\frac{cm^{3}}{s}[/tex]
El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.
Find x and y
(45-45-90 formula)
(It’s not 5.6 for x and y I got that wrong)
I’ll mark as brainliest!!
Answer:
x = y = 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] ( multiply both sides by 8 )
8 × cos45° = x , then
x = 8 × [tex]\frac{\sqrt{2} }{2}[/tex] = 4[tex]\sqrt{2}[/tex]
The third angle in the triangle = 45° ( sum of angles in triangle )
Then the triangle is isosceles with congruent legs, thus
x = y = 4[tex]\sqrt{2}[/tex]

3 |X-4| +1 = 19
it says what to do in the problem :)
Answer:
Step-by-step explanation:
1). (10x - 27)° = (2x + 29)°
10x - 27 = 2x + 29
8x = 56
x = 7
m∠W = (2(7) + 29)° = 43°
2). (14x + 4)° + 51° + 55° = 180°
14x + 110 = 180
x = 14

Find the area of this figure.
Round your answer to the

5 ft
5 ft
A = [ ? ] ft2
Notice that only half of the circle is included in the figure!
9514 1404 393
Answer:
26.13 ft²
Step-by-step explanation:
The total area is twice the area of the right triangles plus half the area of a circle of radius 3 ft.
Semicircle area = (1/2)(πr²)
semicircle area = (1/2)(3.14)(3 ft)² = 14.13 ft²
The area of the two right triangles is ...
total triangular area = (3 ft)(4 ft) = 12 ft²
Then the area of the figure is ...
figure area = semicircle area + total triangular area
= 14.13 ft² + 12 ft² = 26.13 ft²
Answer: 26.13

y=5x+1
Answer:
X= [tex]\frac{1}{5\\}[/tex] y+ 1[tex]\frac{-1}{5}[/tex]
Step-by-step explanation:
y=5x+1
Step 1: Flip the equation.
5x + 1
Step 2: Add -1 to both sides.
5x + 1 + −1 = y+ −1
Step 3:
Divide both sides by 5.
[tex]\frac{5x}{5\\}[/tex]= [tex]\frac{y-1}{5}[/tex]
The net of a square pyramid is shown in the diagram.
What is the total surface area of the square pyramid in square inches?
Answer:
208
............
The total surface area of the square pyramid is 208 square inches.
What is Area?
Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is to find the total surface area of the square pyramid in square inches.
We can write the total surface area of the square pyramid as -
A{total} = A{square} + 4 x A{Δ}
A{total} = (8 x 8) + (4 x 1/2 x 8 x 9)
A{total} = 64 + (16 x 9)
A{total} = 208 square inches
Therefore, the total surface area of the square pyramid is 208 square inches.
