Sixteen added to a number is equal to forty. Find the number.

Answer:

83.5%

Step-by-step explanation:

Answer:

B, 83.5%

Step-by-step explanation:

I got you dude, I math this out all the time. You divide how many points you have by how many points total to get the answer. You’ll need 3758 to get a A- (total points x 0.9)

Answer:

A) 1x 9^6

B) 1 x (2/3)^4

C) 1 x 4.5^6

hope that helps!

add me as a friend if you can:)

Answer:

A.  [tex]9^{6}[/tex]

B. [tex](\frac{2}{3} )^{4}[/tex]

C. [tex]4.5^{6}[/tex]

Step-by-step explanation:

- the 1 in the front dosn't matter since 1 times "number" is going to be that number

A. There are six 9's multiplying by each eachother

B. There are four (2/3)'s multiplying by each eachother

C. There are six 4.5's multiplying by each eachother

Answer:  [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex]

The sin(A) goes with 'a'

sin(B) goes with b

sin(C) goes with c

Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)}[/tex] and [tex]\frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex] and [tex]\frac{a}{\sin(A)} = \frac{c}{\sin(C)}[/tex]

Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.

Answer:

157

Step-by-step explanation:

8.00 +(0.06x) = 18.27

0.08x = 18.27 - 6.00

0.08x = 12.56

12.56/0.08=

157

Answer: X

Step-by-step explanation: The Square root of 68 is 8.246, meaning the closest point to that number is X.

Answer:

y = 3x - 1

Step-by-step explanation:

→ Substitute x = 1 into all the equations to get y = 2

y = 3x - 1 ⇔ ( 3 × 1 ) - 1 = 2

Answer:

D

Step-by-step explanation:

You can answer this question without even worrying about slope if you know how the y-intercept should be. The y-intercept is where the line crosses the y-axis(the vertical line with the y label in case that needs to be explained.) With that alone, you can determine that the y-intercept is -1 and thus the answer is D. For the slope, try to find a point on the line that is on the grid (A good one is (0,-1) ). Then move from that point to the next point where two of the lines meet like (1,2). Slope is rise/run so you go 3 up and 1 to the right for 3/1 which equals 3.

Answer:

Y= (4, -5)

Step-by-step explanation:

________________

Z corresponds to D

W corresponds to A and

X correspondents to B

rotate it in your mind

from D to C gives you a good clue where to place Y.

4,-5 is correct

Edited:

(-1,3)

read the text wrong. but the method below holds :D

Step-by-step explanation:

The intersection of the AC line with the BD line is at (1,3)

method: hold an old receipt on my phone screen. would describe it as a graphically approach to the solution

on paper a ruler would be enough to draw the two mentioned lines.

do you need an algebraic way to do it?

Answer:

x<5

Step-by-step explanation:

since the CD is a one time purchase, his total amount of money after would be 25.

40-15>6x

25>6x (still have to solve for x)

4.166>x

x<5 (since it has to be a whole number)

Step-by-step explanation:

the answer is in the above image

Answer:

$281.88

Step-by-step explanation:

Solve for 50% of $522:

522 × 0.50

261

Solve for sales tax:

261 × 0.08

20.88

Solve for total:

261 + 20.88

281.88

Answer:

statement 1 and 2 are true

Answer:

1) 5, 7, 8

2) 10, 24, 26

Step-by-step explanation:

1) For an acute triangle, the square of the longest side is less than the sum of the square of the two smaller sides.

a) 4² + 5² = 16 + 25 = 41

7² = 49 > 4² + 5².  Therefore the triangle is not acute

b) 5² + 7² = 25 + 49 = 74

8² = 64 < 5² + 7².  Therefore the triangle is acute

c) 6² + 7² = 36 + 49 = 85

10² = 100 > 6² + 7².  Therefore the triangle is not acute

d) 7² + 9² = 49 + 81 = 130

12² = 144 > 7² + 9².  Therefore the triangle is not acute

2) For a right angled triangle, the square of the longest side is equal to the sum of the square of the two smaller sides.

a) 8² + 12² = 64 + 144 = 208

15² = 225 > 8² + 12².  Therefore the triangle is not a right triangle.

b) 10² + 24² = 100 + 576 = 676

26² = 676 = 10² + 24².  Therefore the triangle is a right triangle.

c) 20² + 12² = 400 + 144 = 544

25² = 625 > 20² + 12².  Therefore the triangle is not a right triangle.

d) 15² + 18² = 225 + 324 = 549

20² = 400 < 15² + 18².  Therefore the triangle is not a right triangle.

Answer:

Answer:

1. 6.96500 kilogramos

2. 3.95 kilogramos

Answer:

option B

Step-by-step explanation:

According to Euclidean Geometry , opposite side and opposite angles of parallelogram are equal.

That is,

( 6x + 12 )° = (7x - 8 )°

Answer:

1/6

Step-by-step explanation:

6^-2  / 6^-1

We know that a^b / a^c = a^(b-c)

6^(-2 - -1) = 6^(-2+1) = 6^-1

We know that a^-b = 1/a^b

1 /6^1 = 1/6

Answer:

1/6

Step-by-step explanation:

When dividing by exponents, you need to subtract the exponent from top to bottom. Ex: 5^3/5^2=5^1 which is just one, because you subtract 3 and two. In this case, 6^-2 / 6^-1 gets us 6^-1 which is the same thing as 1/6^1. Because remember, a^-x = 1/a^x.

Hope this helps!
