Answer:

0.20 hour

Step-by-step explanation:

According to the problem, computation of the given data are as follows,

Speed of police = 90 mph

Speed of chased car = 85 mph

Distance to be chased = 1 mile

So, we can calculate the time to catch by using following formula:

Time required = Distance between two cars ÷ (Speed of Car A - Speed of Car B)

= 1 ÷ ( 90 - 85)

= 1 ÷ 5

= 0.20 hour

Sorry I am stupid but I need help
nikklg [1K]

I believe the answer to your question is the first choice.

Since we have two sides that are 24 mm that means that the equation needs to have 2(24 mm).

And since we have 4 sides that are 18 mm, it means that the equation needs to have 4(18 mm).

so we get: P= 4(18 mm) + 2(24 mm)


Hope this helped and plz mark as brainliest!

Determine if y varies directly with x. Give the constant of variation, when appropriate. (picture below)
maxonik [38]

Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.

<h3>Variation</h3>

y = k × x

where,

k = constant of proportionality

y = -40

x = -5

y = k × x

-40 = k × -5

-40 = -5k

k = -40/-5

k = 8

when,

y = 8 and x = 2.5

y = k × x

8 = k × 2.5

8 = 2.5k

k = 8/2.5

k = 3.2

when,

y = 5 and x = 4

y = k × x

5 = k × 4

5 = 4k

k = 5/4

k = 1.25

Jacinta scores 23, 19, and 27 on three of her four tests. She wants to get an
pochemuha

Answer:

23+19+27+x = 96

x > 27

not sure if the answer can be left that way or do you assume that test results are whole numbers, if so then the answer  would b=have to be 28.. but I think that >27 is the answer expected

Which point below is a solution to the equation y = 2x + 3?
Anastasy [175]

Answer:

C (37, 77)

Step-by-step explanation:

<h3>Option A:</h3>

291=2(145)+3\\\\291=290+3\\\\\boxed{291\neq 293}

Option A is not a solution.

<h3>Option B:</h3>

163=2(78)+3\\\\163=156+3\\\\\boxed{163\neq 159}

Option B is not a solution.

<h3>Option C:</h3>

77=2(37)+3\\\\77=74+3\\\\\boxed{77=77}

Option C is a solution.

Hope this helps.
