Answer:

0.75 - 0.25 + 1/2

convert the decimals to fractions

that's

0.75 = 3/4

0.25 = 1/4

We get

3/4 - 1/4 + 1/2

Find the common denominator which is 4

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

=4/4

= 1

The final answer is 1

Hope this helps

Answer:

The quotient is 48.

Step-by-step explanation:

Estimate the quotient using compatible numbers:

45 (or I guess any number close the answer above, not sure tbh)

Multiply the estimate by 21:

945

45*21

Is the estimate to high or too low?

too low

Adjust and continue until the product is 1008.

1008/21=48

Have a good day/evening! I hope my answer is correct!

What is the distance between (5, -1) and (5,-4)
jarptica [38.1K]

Answer:

Step-by-step explanation:

To evaluate for such, the following comprehension is required,

Equation Required: Distance Formula: d(P, Q) = √ (x2 − x1)^2 + (y2 − y1)^2

Denote the configurations as the following,

(5, -1). (5, -4)

X1 Y1. X2. Y2

D(P, Q) = √(5 - 5)^2 + (-4 +1)^2. <== Since the double negative is present, the operation is acknowledged as positive.

D(P, Q) = √(0)^2 + (-3)^2

D(P, Q) = √9 = 3

Thus, the agglomerate distance between the points situated in the Cartesian plane is disclosed, and is, henceforth, disseminated as 03 units.

Determine if the following equations are equal by evaluating both sides
padilas [110]

Answer:

Yes, the both sides of the given equation are equal.

Step-by-step explanation:

The given equation is

\log((1-i)^3)=3\log(1-i)

Taking LHS,

LHS=\log((1-i)^3)

Using the power property of logarithm, we get

LHS=3\log(1-i)                               [\because log_ax^n=nlog_ax]

LHS=RHS                                   [\because RHS=3\log(1-i)]

Both sides of the given equation are equal.

I need help with exercises 3,4, and 6 please show all work and don’t answer number 5 just tell me if it is correct

*If you need me to do #5, DM me!

3. 
The area of a triangle can be given by (just plug and chug as always):
A_t = \frac{1}{2} bh = \frac{1}{2}(3)(4) = 6ft^2
The area of the triangle is 6ft².

4. I will divide into a triangle and a rectangle (because the actual equation for the area of a pentagon requires it to be a perfect pentagon). Let's do the triangle first (height is 3 because you subtract 12 from 15):
A_t = \frac{1}{2} bh = \frac{1}{2}(8)(3) = 12m^2
A_r = bh = 12(8) = 96m^2
Now we just add them:
96+12 = 108m^2

So, the area of that pentagon is 108m².

5. You are actually wrong on this one because the area of a triangle is:
A_t = \frac{1}{2}bh
So, just halve your answer and it will be correct.

6. We can just split it into 4 triangles of equal area and then multiply the area of 1 triangle by 4 to get the total area. Let's do just that:
A_t = \frac{1}{2}bh = \frac{1}{2}(2.5)(5) = 6.25cm^2
Multiply by 4 to get total area:
6.25*4 = 25cm^2

So, the area of the given rhombus is 25cm².

The diagonal of a TV is 30 inches long. Assuming that this diagonal forms a pair of 30-60-90 right triangles, what are the exact
Nutka1998 [239]
The ratio of sides for a 30 : 60 : 90 =  1 : √3 :2.

Note the 90 degrees represent the hypotenuse, which in this case is 30 inches.

<span>1 : √3 :2 =  x : y : 30
</span>
To get 1, on the left side, we simply divide 2 by 2

Similarly x = 30/2 = 15.

To get √3, on the left side, we simply multiply 1 by √3

Similarly y = 15 * √3 = 15√3

<span>Therefore the length and width respectively are </span>15 and 15√3 inches<span> </span>
