PLS HELP!!! The snowy tree cricket is sometimes called the temperature cricket because the frequency of its chirps varies based

trasher [3.6K]

Answer:

Step-by-step explanation:

62 degrees Fahrenheit

Step-by-step explanation:

The number of snowy tree cricket chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit.

Let x = number of chirps

f = temp in Fahrenheit

x = 4f -148

Now let x = 100

100 = 4f-148

Add 148 to each side

100+148 = 4f-148+148

248 = 4f

Divide each side by 4

248/4 = 4f/4

62=f

Late work 4 physics

Oliga [24]

Answer:

Step-by-step explanation:

problem 4

Velocity is +2.0m/s and constant acceleration is -0.5m/s^2

For every second the velocity drop by 0.5 m/s, so after 2 seconds the velocity is 1 m/s.

problem 5

Accelerate from rest to 28m/s means go from 0 to 28m/s so with

a constant acceleration of 5.5 m/s^2 it will take 5.09 second

Which rules of exponents will be used to evaluate the expression. Check all that apply

julia-pushkina [17]

Hello!

The answer are:

- Product of powers.

- Power of a power.

- Negative exponents.

Let's solve it!

It's a math rule that we must solve first what's into a brake or parenthesis, so,

First: Product of powers $[(7)^{5}*(7)^{3}]$

According to the exponent's law, we have a product of powers case, so, we need to sum the exponents and keep the base

Exponents: 5 and 3

Base: 7

Applying it we have:

$(7)^{5+3}$

$(7)^{8}$

Then,

We have a power of a power case, which involves multiplying the exponents:

$[(7)^{5}*(7)^{3}]^{-4}$

Exponents: 3 and -4

Then,

$(7)^{8*-4}$

Finally, we can apply the negative exponents, the negative exponent's rules state that negative exponents are the reciprocal of the positive exponents,

So, we will have that:

$(7)^{-32}=\frac{1}{7^{32} }$

Have a nice day!

The number of pumps in use at both a six-pump station and a four-pump station will be determined. Give the possible values for e

notsponge [240]

Answer:

a. T = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

b. X = { -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}

c. U = {0, 1, 2, 3, 4, 5, 6}

d. Z = {0, 1, 2}

Step-by-step explanation:

n1 = 6 pumps

n2 = 4 pumps

a. The total number of pumps in use:

The number of pumps in use can range from 0 (no pumps used in both stations) to 10 (all pumps used in both stations), assuming all integers in between. Thus, the set T is:

T = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

b. The difference between the numbers in use at stations 1 and 2 can range from -4 (no pumps in station 1 and all pumps in station 2 being used) to 6 (all pumps in station 1 and no pumps in station 2 being used), assuming all integers in between. Thus, the set X is:

X = { -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}

c. The maximum number of pumps in use at either station is given by the possible numbers of pumps at use in station 1 (From 0 to 6). The set U is:

U = {0, 1, 2, 3, 4, 5, 6}

d. The number of stations having exactly two pumps in use can be neither, one or both. The set Z is:

Z = {0, 1, 2}

Ariane borrows $200 on a 5 year loan she is charged 5% simple interest how much interest is she charged for 5 years what is the

ycow [4]

Answer:

Interest: $50 | Total: $250

Step-by-step explanation:

You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.

$I = Prt$

<em>I = interest amount </em>

<em>P = principal amount </em>

<em>r = interest rate (decimal form) </em>

<em />

Now we can plug in the values into the equation:

$I = 200(.05)(5)$

$I = 50$

This means that Ariane is charged $50 worth of interest. She has to pay back $250 total dollars.
