At the start of the week, an account had a balance of –$12.67. So far during the week, $20 has been deposited into the account and $13.47 has been spent from the account. At the end of the week, the balance needs to be at least $25 in the account. What is the minimum amount of money, in dollars, that still needs to be deposited into the account before the end of the week?

Answer:

r = 0.05 or 5%

Step-by-step explanation:

3450 = 3000 + (3000 · r · 3)

450 = 9000 · r

450/9000 = r

r = 0.05 or 5%

Answer:

191 Feet.

Step-by-step explanation:

Answer: Your answer should be 191!

Answer:

We have to first see that the given lengths makes a triangle or not by using a+b > c in which a,b and c are

length of sides of a triangle lets check out

16 + 21 = 37 > 28

21 + 28 = 49 > 16

16+ 28 = 44 > 21

As because the statement fits correct in the lengths given so its a triangle

So we can say that the triangle is scalene by means of measurements

but cant be a right angle as by taking the pythagorean triplet

= a^2 + b ^ 2 = c^2

lets see if a=16, b = 21 and c = 28

So a^2 + b^2

= 256 + 441

= 697

but c^2

= 28^2 = 784

As 441 =/= 784

So The triangle lengths cant be a right angled triangle

So 1/2 of possibility is the traingle acute and 1/2 of the possibilty that the triangle is obtuse

Now you can find the correct triangle on the basis of acute or obtuse angle by drawing with given length of sides of triangle

Answer:

13

Step-by-step explanation:

Once again we are looking at inscribed angles and intercepted arcs. Like stated previously an inscribed angle is equal to half its intercepted arc

That being said we want to create an equation to solve for x

The equation would be 7x + 5 = 192/2

We now solve for x

step 1 simplify

192/2=96

now we have 7x + 5 = 96

step 2 subtract 5 from each side

5 - 5 cancels out

96 - 5 = 91

7x = 91

step 3 divide each side by 7

7x/7 = x

91 / 7 = 13

we're left with x = 13

Answer:

D.0

Step-by-step explanation:

If you graph the equation you can see that it doesn't cross the x-axis. It doesn't go lower than y=1. If you don't have a graphing calculator use Desmos. Also the +1 at the end of the equation tells you that it won't go lower than y=1.

Answer:

Never your answer is 0

Step-by-step explanation:

The equation creates what's called a parabola the line curves up the 1 represents the y axis so the line curves up from the y axis point 1 never touching the x axis

Answer:

Step-by-step explanation:

Sum of angles of a triangle = 180

x + (180 - 105) + (180 -140) = 180

x + 75 + 40 = 180

x = 180 -75 - 40

x = 65

Answer:

4ft

Step-by-step explanation:

to get the area of a square you multiply the sides together so you just find the square root of the area

Answer:

4 feet would be the legth of the squares side

Step-by-step explanation:

t16 is the squares area and the area of a square is length X width, since all the sides of a square are equal, we can just take the square root of  16 which is 4 feet.

Answer:

Step-by-step explanation:

(10-10) (10+2)

0 X 12=0

Answer:

0

Step-by-step explanation:

In order to solve this, we just substitute 10 instead of r, and get...

(r - 10)(r + 2) = (10 - 10)(10 + 2) = (0)(12) = 0

Answer:

∠A = 126°

Step-by-step explanation:

Supplementary angles are angles that add up to equal 180°

Given that ∠B = 54°, we can subtract 54° from 180°.

180° - 54° = 126°

∠A = 126°

Answer:

The HCF is 75

Step-by-step explanation:

Here, we want to get the highest common factors of the two numbers

To do this, we have to write the numbers as the product of their prime factors

We have;

3,000 = 2 * 2 * 2 * 3 * 5 * 5 * 5

525 = 3 * 5 * 5 * 7

now looking at this, we can see that in both numbers, we can have 3 * 5 * 5 taken out as it is common to both numbers

This represents the highest common factor of the two numbers

and that is 75

Answer:

mean = 2

median = 2.5

Step-by-step explanation:

There are a total of 20 goals  (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)

There are 10 games, so 20/10 = 2 = mean

Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5.  So the median is 2.5
