Joshua after all his spending has $7.75 at the end of the month

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let, The savings and his work be denoted by a positive amount and his spending be donated by a negative amount.

So, From the information given his savings of $20.50 and his work of mowing the lawn for $7.50 and washing a car for $3.75 should be added which is,

= $(20.50 + 7.50 + 3.75).

= $31.75

Now, we'll subtract all his spending,

= $(31.75 - 5.25 18.75).

= $7.75.

The range of possible value for x is  3/2< x <24 , using properties of angle and sides.

How sides and angles are related ?

Side opposite to larger angle is always larger than other.

Here,

In  ΔBCE and ΔCED

BE=DE

CE=EC

AND BC>CD

So, from above statement, ∠BEC > ∠CED

then,

45 > 2x - 3

48 > 2x

24 > x  or  x < 24

And, angle is always greater than 0

So, 2x - 3 > 0

      2x > 3

      x > 3/2.

So, option 3rd is correct.

to round to the nearest hundredths look at thousandths 7 becasuse is greater then 5 then you round up

106.327 is rounded to 106.33

Answer:

your answer is 106.3

Step-by-step explanation: so first you do this

Answer:

x = 20

y = 19

Step-by-step explanation:

(2x - 3)° + (3x - 7)° = 90° (complementary angles)

(2x - 3 + 3x - 7)° = 90°

(5x - 10)° = 90°

5x - 10 = 90

5x = 90 + 10

5x = 100

x = 100/5

x = 20

2y - 1 = 2x - 3 ( vertical angles)

2y = 2x - 3 + 1

2y = 2x - 2

2y = 2*20 - 2 (plug x = 20)

2y = 40 - 2

2y = 38

y = 38/2

y = 19

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

Given the equation;

3. 5 (1.25x + 0.5) = 10.5

Open the parenthesis

3.5(1.25x) + 3.5(0.5) =10.5

4.375x + 1.75 = 10.5

4.375x + 1.75 -1.75= 10.5-1.75

4.375x = 8.75

Divide both sides by 4.375

4.375x/4.375 = 8.75/4.375

x = 2

Hence the solution to the equation is 2

Answer:

-7.5 ft^3/sec

OR

Volume is decreasing at the rate of 7.5 ft^3/sec

Step-by-step explanation:

Side of cube = 10 feet

Rate of decreasing of side of cube = [tex]\frac{1}{10}\ feet/sec[/tex]

OR

Rate of change of side of cube = [tex]-\frac{1}{10}\ feet/sec[/tex]

To find:

Rate of change in volume when the edge is 5 feet long = ?

Solution:

Volume of a cone is given by:

[tex]V =Side^3[/tex]

If side is [tex]a[/tex] units, then Volume can be written as:

[tex]V =a^3[/tex]

Differentiating w.r.to time:

[tex]\dfrac{dV}{dt} = 3a^2\dfrac{da}{dt}\\\Rightarrow \dfrac{dV}{dt} = 3\times 5^2(-\frac{1}{10})\\\Rightarrow \dfrac{dV}{dt} = -7.5 ft^3/sec[/tex]

Negative sign indicates that the volume is decreasing at the rate of 7.5 ft^3/sec

Answer:

n = 5,000 - 12t ​

Step-by-step explanation:

Sam is handing out advertisements for an upcoming event.

No of advertisements = 5000

No of advertisements per minute is 12.

We need to find the equation that best models the relationship between the amount of time t, Sam spends handing out advertisements and the number of advertisements, n, remaining.

5000 is fixed and there are 12 advertisements per minute. Let the equation is given by :

n = 5,000 - 12t ​

Hence, the correct option is (d).

Answer:

the gas mileage would be 21.12 mi/gal

Step-by-step explanation:

The computation of the gas mileage is shown below:

Given that

Driving into a 20-mph

Gas mileage by approx 12%

No wind at 24mi/gal

based on the above information

The deduction would be

= 12% × 24

= 2.88 mi/gal

Now the actual mileage in 20-mph would be

= 24 - 2.88

= 21.12 mi/gal

hence, the gas mileage would be 21.12 mi/gal
