Lena drive 696 miles in 12 hours. At the the same rate, how long would it take her to drive 522 miles?

Answers

Answer:

It would take Lena 9 hours.

Step-by-step explanation:

Looking at the problem I can do 696/12 to get the number of miles per hour she is traveling which is 58. With this number, I can take 522/58 to get 9 hours.

Answer:

Step-by-step explanation:

Remark

The best way to do this is to set up a proportion. It can be done by using d = r * t twice, but a more direct way is to use the proportion.

Formula

distance1 / time1 = distance2 / time2

Givens

distance1 = 696 miles

time1 = 12 hours

distance2 = 522 miles

time2 = x

Solution

696/12 = 522/x       Cross multiply

696 * x = 522* 12    Combine the right

696 * x = 6264        Divide by 696

x = 6264/696

x = 9 miles

Option C. Side a 1.5 inches long, side b is 2 inches long and side c is 2.5 inches long

Step-by-step explanation:

The scale factor=4:1=4/1

Scale factor=(Scale drawing)/object

4/1=6/a

4a=6

a=6/4

A=1.5 inches

4/1=8/b

4b=8

b=8/4

B= 2 inches

4/1=10/c

4c=10

c=10/4

C=2.5 inches

Therefore, side a is 1.5 inches long and side b is 2 inchea long and side c is 2.5 inches long

Answer:

C

Step-by-step explanation:

with the scale factor being 4:1 (meaning shape A is bigger then shape B by 4 times) we can divide the larger shapes dimensions by 4 to get ur answer

the diagram shows a right angle triangle..

Answers

Area of triangle = base x height x 1/2

18 = (x - 1) • (x + 4) • 1/2

18 • 2 = (x - 1) • (x + 4)

36 = (x - 1)(x + 4)

36 = (x² + 4x - 1x - 4)

36 = x² + 3x - 4

0 = x² + 3x - 4 - 36

x² + 3x - 40 = 0

(x + 8)(x - 5) = 0

x + 8 = 0 or x - 5 = 0

x = -8 or x = 5

“-8” is rejected, as length/width/height can’t be negative.


The length of the shortest side the triangle:

Short side = x - 1

Answers

Answer:

f(x)=-2x^2+32x-114

Step-by-step explanation:

Answer:

f(x) = -2x^2 + 142

Step-by-step explanation:

f(x) = -2(x - 8)^2 + 14

f(x) = -2(x)^2 - (-2)(-8)^2 + 14

f(x) = -2x^2 - (-2)(64) + 14

f(x) = -2x^2 - (-128) + 14

f(x) = -2x^2 + 128 + 14

f(x) = -2x^2 + 142

solve the following equation​

Answers

Answer: I think it is x= 3/74

Step-by-step explanation:

Answer:

x=3/74

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

20/3x=1/2x+1/4

Step 2: Subtract 1/2x from both sides.

20/3x-1/2x=1/2x+1/4-1/2x

37/6x=1/4

Step 3: Multiply both sides by 6/37.

(6/37)*(37/6x)=(6/37)*(1/4)

x=3/74

Thus, your answer will be x=3/74.

A sine curve with a period of 8, an amplitude of 2, a left phase shift of /3, and a vertical translation down 5 units.

Answers

Answer:

[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]

Step-by-step explanation:

The standard form for a sinusoidal function is given by:

y = Asin[B(x - C)] + D

Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation

Given:

A = 2, D = -5 (down), C = -3 (left).

8 = 2π/B; B = π/4

Therefore:

[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]
