Answer:

Step-by-step explanation:

Increase

Increase = [tex]\dfrac{4}{5}-\dfrac{2}{5}=\dfrac{2}{5}[/tex]

Increase percentage = 2/5 out of 2/5 * 100

                                    [tex]=\dfrac{2}{5}*\dfrac{5}{2}*100[/tex]

                                     = 100 %

Answer:

1. has solution x=-2 and goes in the left circle

2. has solutions x=-2 and x=5 and goes in the intersection between the two circles

3. has solution x=-2 and goes in the left circle

4. has solution x=5 and goes in the right circle

Step-by-step explanation:

Solve each equation by factoring

2x^2-12x-32=0

2(x^2-6x-16)=0

2(x+2)(x-8)

x=-2,x=8

Therefore, 1. has solution x=-2 and goes in the left circle

2x^2-6x-20=0

2 (x^2-3x-10) = 0

2(x-5)(x+2)=0

x=-2,x=5

Therefore, 2. has solutions x=-2 and x=5 and goes in the intersection between the two circles

3x^2+2x-8=0

(x+2)(3x-4)=0

x=-2, x=4/3

Therefore, 3. has solution x=-2 and goes in the left circle

3x^2-18x+15=0

3(x^2-6x+5)=0

3(x-1)(x-5)=0

x=1,x=5

Therefore 4. has solution x=5 and goes in the right circle

Hey there :)

An exact answer cannot be given as it requires to reseach about banks and co-operatives in your locality. However, I can give you a hint.

Research banks or cooperatives in your location that has the greatest percentage in terms of investment or savings.

Let's say, for example, Bank ABC has 5% annual simple interest in their Savings Account.

If you invest your entire money 100,000 pesos at Bank ABC with 5% annual interest for 20 years, you will earn an interest of:

[tex]Interest = Principal \times Rate \times Time[/tex]

[tex] = > Interest =100000 \times 0.05 \times 20yrs[/tex]

[tex] = > Interest = 100000[/tex]

Hence, after investing at Bank ABC for 20 years, you will earn 100,000 pesos on top of your principal/invested amount that is 100,000 pesos. Your money will become 200,000 pesos now.

So, with this, find a bank/cooperative that has the highest return rate in your location. Once you have decided bank/cooperative, research further with regards to the background of the company, other services offered, application requirements, etc.

Answer:

V = 3322.6 ft³

Step-by-step explanation:

V(rt cone) = [tex]\frac{\pi r^2h}{3}[/tex]

V = [π(17.2/2)²(14.3)] ÷ 3

V = π(8.6)²(14.3)

V = 73.96(14.3)π

V = 3322.6

Answer:

a=28; b=20.

Step-by-step explanation:

1) 2*(-4)=(a+b)+(-2a) and .

2) using the two equations it is possible to make up (then solve) the next system:

[tex]\left \{ {{2*(-4)=(a+b)+(-2a)} \atop {2*8=3b+(2b-3a)}} \right. \ => \ \left \{ {{-a+b=-8} \atop {-3a+5b=16}} \right. \ => \ \left \{ {{a=28} \atop {b=20}} \right.[/tex]

Answer:

12 - x

Step-by-step explanation:

y = -x + 12

Replace x with y.

x = -y + 12

Solve for y, x = -y + 12

Answer:

x=5

Step-by-step explanation:

Answer:

x = 68

Step-by-step explanation:

The formula for calculating the sum of interior angles of a polygon is: (n - 2) x 180° (where n is the number of sides)

This polygon has 5 sides, so the sum of the interior angles:

(5 - 2) x 180° = 540°

To find x, add together all the angle expressions, equate to 540 and solve for x:

                                                       U + V + W + Y + Z = 540

                       (x - 8) + (3x - 11) + (x + 8) + x + (2x + 7) = 540

Gather like terms:  x + 3x + x + x + 2x - 8 - 11 + 8 + 7 = 540

Combine like terms:                                           8x -4 = 540

Add 4 to both sides:                                               8x = 544

Divide both sides by 8:                                             x = 68

Step-by-step explanation:

First, you rewrite the problem as shown in the image.

After this, you may reduce the fraction and simplify.

Once you do this, the answer will be -7ss/rr.

(I used rr and ss but it would have the numbers).

The expression represents the probability of getting exactly 3 heads is [tex]\rm= ^9C_3 \times (0.5)^3\times (0.5)^{6}[/tex].

Aron flips a penny 9 times.

We have to determine

Which expression represents the probability of getting exactly 3 heads?

The binomial distribution is determined as the probability of mass or discrete random variable which yields exactly some values.

The binomial probability formula shown has variables which represent:

[tex]\rm= ^nCr \times p^r\times (1-p)^{n-r}[/tex]

Where n is the total number of trials (here, we flip penny 9 times, hence n = 9).

r is the number we want to find (here, we want the probability of 3 heads, so r = 3).

p is the probability of success (here, success means getting heads.

So, in a coin flip the probability of heads is always 1/2, so p = 1/2).

Therefore,

The expression represents the probability of getting exactly 3 heads is;

[tex]\rm= ^nCr \times p^r\times (1-p)^{n-r}\\\\\rm= ^9C3 \times (0.5)^3\times (1-0.5)^{9-3}\\\\= ^9C3 \times (0.5)^3\times (0.5)^{6}[/tex]

Hence, the expression represents the probability of getting exactly 3 heads is [tex]\rm= ^9C_3 \times (0.5)^3\times (0.5)^{6}[/tex].

Answer:

245% Increase

Step-by-step explanation:

1) Divide the price of the following day by the previous one.

441/180 = 2.45

2) Multiply by 100 to convert from decimal to percentage.

2.45 * 100 = 245%

3) There was a 245% increase in the price of an item from yesterday to today.

Answer:

shaded area = total area - the two triangles areas

total area = 5*9 = 45 cm²

first tri area = 1/2 * h *b

= 0.5 * 5 * 2 = 5 cm²

second tri area = 0.5 * 6 * 5 = 15 cm²

shaded area = 45 - 15 - 5 = 25 cm²

Answer:

Slope

A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\display style m>0} .

A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\display style m<0} .

If a line is horizontal the slope is zero. This is a constant function.

If a line is vertical the slope is undefined (see below).
