Really, you could say that he has 9 twenties, and 4 fives, but that would be impractical.

Answer:

Step-by-step explanation:

(-4 - 5i)⋅(1 - i) = (-4)(1) + (-4)(-i) + (-5i)(1) + (-5i)(-i)

= -4 + 4i - 5i + 5i²

= -4 - i -5

= -9 - i

Answer:

300

Step-by-step explanation:

1100 = 900 [tex]e^{k*20}[/tex]

1.222222 =  [tex]e^{k*20}[/tex]

ln(1.222) = 20k ln(e)

k = ln(1.222)/20

k = .2004

900 = x [tex]e^{15* .20004}[/tex]

900/x =    [tex]e^{15* .20004}[/tex]

 [tex]e^{15*.2004} = 900/x[/tex]

x = 900/   [tex]e^{15*.2004}[/tex]

x = 300

Answer:

183.3 in^3

Step-by-step explanation:

Find the volume of the rectangular bottom

V = l*w*h

V = 5*5*6 =150 in^3

Find the volume of the triangular pyramid

V = 1/3 Bh where B is the area of the base and h is the height

V = 1/3 ( 5*5) * 4 = 100/3

Add the two volumes together

150 + 100/3

150 +33.3

183.3 in^3

Answer:

2. Not Divisible

3. Divisible

4. Divisible

5. Divisible

6. Not Divisible

7. Divisible

Step-by-step explanation:

Question 2. Is 629,257 divisible by 5?

- Numbers that are divisible by 5 should end with either 5 or 0.

- The ending term of [629,257] is 7, which is neither 5 nor 0. Therefore, it is not divisible.

Question 3. Is 3,791,916 divisible by 2?

- Numbers that are divisible by 2 should end with an even number or 0, which include 0, 2, 4, 6, 8.

- The ending term of [3,791,916] is 6, which is an even number. Therefore, it is divisible.

Question 4. Is 63,726,125 divisible by 5?

- Numbers that are divisible by 5 should end with either 5 or 0.

- The ending term of [63,726,125] is 5. Therefore, it is divisible.

Question 5. Is 486,342 divisible by 3?

- In numbers that are divisible by 3, the sum of all digits is a multiple of 3.

- The sum of all digits of [486,342] is [4 + 8 + 6 + 3 + 4 + 2 = 27].

- 27 / 3 = 9

- Since the sum of all digits is divisible by 3, then 486,342 is divisible by 3.

Question 6. Is 474,493 divisible by 10?

- Numbers that are divisible by 10 should end with 0.

- The ending term of [474,493] is 3, which is not 0. Therefore, it is not divisible.

Question 7. Is 53,017,587 divisible by 9?

- In numbers that are divisible by 9, the sum of all digits is a multiple of 9.

- The sum of all digits of [53,017,587] is [5 + 3 + 0 + 1 + 7 + 5 + 8 + 7 = 36].

- 36 / 9 = 4

- Since the sum of all digits is divisible by 9, then 53,017,587 is divisible by 9.

Step-by-step explanation:

Given,

the bigger triangle (∆GFH), <HGF = 90° and <GFH = 60° and GF = 4

In the 30-60-90 triangle, FH = 4×2 = 8

or you can find it like this,

cos60 = 4/FH

FH = 4/cos60 = 8

Now, I is the midpoint of FH, so, FI = 8/2 = 4

now for ∆FGI,

<GFI = 60°, GF = 4, FI = 4, it's a equilateral triangle, so we can say GI = 4

Now we need to find the height of ∆FGI, for that,

area of ∆FGI = (√3/4)×4² = 4√3 = 6.92820323..

So height (GJ) = 2×area/side = 2×4√3/4 = 2√3 = 3.46410162.. [height of ∆GFI (Because altitude is perpendicular distance from a point) = GJ, given]

now, in ∆GJI, GJ = 2√3, GI = 4 and <GJI = 90° (since itsy altitude, the angle will be a right angle, i.e. 90°)

So, JI = √{4²-(2√3)²} = 2

Area = 2×2√3/2 = 2√3 = 3.46410162.. = 3.46 (rounded to the nearest hundredth)

Answer:

B, C, and D........................

Answer:

6:9

Step-by-step explanation:

Answer:

6 and 9

Step-by-step explanation:

according to the question, the nos. are 2x and 3x.

then, (2x+3)/(3x+3)=3/4

therefore, 4(2x+3)=3(3x+3)

8x+12=9x+9

12-9=9x-8x

3=x

therefore the nos. are 2×3=6 & 3×3=9

Answer from Gauth math

Answer:

[tex]\sqrt[2]{3^7}[/tex]

Step-by-step explanation:

[tex]\sqrt[2]{3^7}[/tex]

The top number is the power and the bottom of the fraction is the root

Answer:

The decimal form of the equation is y = 2.5x + 10

The equivalent fraction form is y = (5/2)x + 10 because 5/2 = 2.5

===========================================================

Explanation:

We can pick any two columns from the table to form the two points needed.

I'll pick the first two columns

(1, 12.5)

(2, 15)

Then apply the slope formula to those points

m = (y2-y1)/(x2-x1)

m = (15-12.5)/(2-1)

m = (2.5)/(1)

m = 2.5

Now use that slope with either point mentioned to find the y intercept b.

y = mx+b

12.5 = 2.5*1 + b

12.5 = 2.5 + b

12.5 - 2.5 = b

10 = b

b = 10

Or

y = mx+b

15 = 2.5*2+b

15 = 5+b

15-5 = b

10 = b

b = 10

We end up with the same b value.

We found that m = 2.5 is the slope and b = 10 is the y intercept

Therefore we go from y = mx+b to y = 2.5x + 10

This is the same as saying y = (5/2)x + 10 since 2.5 = 5/2

Answer:

C

Step-by-step explanation:

this is a "translation" - a shift of the object without changing its shadow and size.

this shift is described by a "vector" - in 2D space by the x and y distances to move.

we have here (1, 0) - so, we move every point one unit to the right (positive x direction) and 0 units up/down.

therefore, C is the right answer (the x coordinates of the points are increased by 1, the y coordinate are unchanged).

[tex]\\ \sf\longmapsto \dfrac{-8-9}{24}[/tex]

[tex]\\ \sf\longmapsto \dfrac{-17}{24}[/tex]

-1/3 + -3/8

denominator: -1/3 * 8

             -3/8 * 3

<=>  -8/24 + - 9/24

<=> (-8 + -9)/24

= -17/24

Answer:

let length be x

b = x - 3

perimeter = 2( l + b)

54 = 2(x+x-3)

27 = 2x - 3

30 = 2x

x = 15

l = 15

b = 15 - 3

b = 12

4a+6b

Step-by-step explanation:

4a -2a +6b +2a

Combine like terms

4a-2a+2a+6b

4a+6b

Answer:

4a + 6b

Step-by-step explanation:

4a - 2a + 6b + 2a

= 4a + 6b

(because -2a and +2a get cancelled by each other)
