Answer:

speed of James is: 3.75 miles/hour.

Step-by-step explanation:

We need to find the speed of James in miles per hour(mi/hr)

we know that 1 mile=5280 feet

James takes 120 steps in 1 minute so he will cover 120×60 steps in 1 hour.

i.e. he takes 7200 steps in 1 hour.

also each step of James=2.75 feet

total distance covered by James in 1 hour=2.75×7200 feet=19800 feet

$19800feet=\frac{19800}{5280} miles=3.65miles$

hence speed of James= (distance covered by james in 1 hour)/1 hour

speed of James=3.75 miles/hour.

Which expression can be used to find the value of expression below -(7/10) + 2/8 + 1/10 - (4/8)

maks197457 [2]

Answer:

(-17)/20

Step-by-step explanation:

Simplify the following:

-7/10 + 2/8 + 1/10 - 4/8

The gcd of 2 and 8 is 2, so 2/8 = (2×1)/(2×4) = 2/2×1/4 = 1/4:

-7/10 + 1/4 + 1/10 - 4/8

The gcd of -4 and 8 is 4, so (-4)/8 = (4 (-1))/(4×2) = 4/4×(-1)/2 = (-1)/2:

-7/10 + 1/4 + 1/10 + -1/2

Put -7/10 + 1/4 + 1/10 - 1/2 over the common denominator 20. -7/10 + 1/4 + 1/10 - 1/2 = (2 (-7))/20 + 5/20 + 2/20 - 10/20:

(2 (-7))/20 + 5/20 + 2/20 - 10/20

2 (-7) = -14:

(-14)/20 + 5/20 + 2/20 - 10/20

-14/20 + 5/20 + 2/20 - 10/20 = (-14 + 5 + 2 - 10)/20:

(-14 + 5 + 2 - 10)/20

-14 + 5 + 2 - 10 = (5 + 2) - (14 + 10):

((5 + 2) - (14 + 10))/20

5 + 2 = 7:

(7 - (14 + 10))/20

Roopesh has $24 dollars to spend on a birthday gift. The store where he is shopping has a sale offering $5 off the regular price

Vinil7 [7]

For this case we have the following data:

Available quantity: $ 24

Regular price: r

Sale price: $r-5$

If we have that Roopesh can not pay more than $ 24, we can write the following inequality, taking into account that the item is sold in $r-5$ :

$r-5 \leq24$

Clearing r:

$r \leq24+5\\r \leq29$

Answer:

What is the unknown?

$r \leq29$

Which expression can represent the sale price?

$r-5$

Which comparison could be used?

The sale price decreases $ 5 and so the regular price is obtained.

The inequality is: $r-5 \leq24$

Laura Bernett is 5 ft-4 inches tall. She stands 12 feet from a streetlight and casts a 5-foot-long shadow. How tall is the stree

Sidana [21]

Answer: the height of the streetlight is 19.47 feet

Step-by-step explanation:

The height of Laura Bernett is 5 ft-4 inches.

12 inches = 1 foot

4 inches = 4/12 = 1/3 foot

Therefore, her height is

5 + 1/3 = 16/3 foot

The diagram of the scenario is shown in the attached photo

The right angle triangle ABC and EBD formed are similar.

h represents the height of the streetlight

Total length of AB = 12 + 5 = 17 feet

Considering triangle BDE,

To determine the angle formed, θ, we would apply trigonometric ratio

Tan θ = opposite side/adjacent side

Tan θ = (16/3)/5 = 1.067

θ = 46.86 degrees

Considering triangle ABC,

Tan θ = h/AB

Tan 48.86 = h/17

h = 17tan48.86 = 17 × 1.145

h = 19.465

To the nearest hundredth,

h = 19.47 feet
