Answer:

a<-4

Step-by-step explanation:

To solve this, you have to isolate a. This means you will have to add 5 to both sides. This will make the equation -2a>8. Divide both sides by 2 to get -a>4. Divide each side by -1 to get a>-4. Because you have to flip the sign when you divide by a negative number, you have to change it into a<-4.

Firs property used : Quotient Property

           [tex]log_b(\frac{X}{Y} ) = log_bX -log_bY[/tex]

   [tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = log_b(\sqrt[3]{x}) - log_b(36y^2)[/tex]

Second property used : Product Property

          [tex]log_b(XY) = log_bX + log_b Y[/tex]

    [tex]log_b(\sqrt[3]{x}) - log_b(36y^2) = (log_b(\sqrt[3]{x}) - [log_b36 + log_by^2)[/tex]

Third property used : Power Property

Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

10n+0.3=0.1n+0.3

Step 1: Subtract 0.1n from both sides.

10n+0.3−0.1n=0.1n+0.3−0.1n

9.9n+0.3=0.3

Step 2: Subtract 0.3 from both sides.

9.9n+0.3−0.3=0.3−0.3

9.9n=0

Step 3: Divide both sides by 9.9.

9.9n/ 9.9 = 0/ 9.9

n=0

Answer:

n=0

Answer:

0

Step-by-step explanation:

10n - .1n = 9.9n

9.9n + .3 = .3

subtract .3 from the other one and get 0

9.9n = 0 then divide and it comes out to 0

Answer:

b*h/2   120*90/2 10800/2=5400

Step-by-step explanation:

The area of the red triangle with sides A= 90 B=120 and C=150 would be equal to 5400.

The area of the triangle is defined as the product of half the base and the height of the triangle.

The area of the triangle = 1/2 x b x h

It is given that the length of the sides are as A= 90 B=120 C=150.

So, The area of the triangle = 1/2 x b x h

= b x h/2  

= 120 x 90/2

= 10800/2

= 5400

Answer:

Probability = 37.5%

Step-by-step explanation:

Prob (Race fast) = 10%, Prob (Slight Fast) = 40%, Prob (Normal Car) = 50%

Prob (Red Car) = 70% of race fast cars, & 45% of slight fast cars, & 30% of Normal cars, & = (70% x 10%) + (45% x 40%) + (30% x 50%) = 7% + 18% + 15% = 40%

Prob (Normal & Red Car) = 30% of 50%  = 15%

Prob (Red car I Normal car) = Prob (Red & Normal Car I Normal Car) =  15% / 40% = 37.5%

x=6

Step-by-step explanation:

3x+4=22

3x=18

x=6

If the total is 22, and you have a number 4 and 3 X's. Then 3x equals 22-4. 3x=18, 18 divided by 3 equals 6. Therefore, x equals 6.

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

The height of the right prism of the surface area given as 2112 square feet is thrice the inverse of the perimeter (h=3/p ft).

The surface area of the right prism is 2112 sq feet.

The length of two parallel sides of the trapezoid is 31 feet and 13 feet and the height is 16 feet.

If the side edges of a prism are perpendicular to its ends or the base, it is called a right prism.

The surface area of the right prism is 2×base area+ perimeter×height

area of base or trapezoid = [tex]\rm \frac{1}{2} \times (sum \: of \: parallel \: sides) \times h[/tex]

[tex]\rm \frac{1}{2} \times (13+31) \times 16\\=352\: ft^{2}[/tex]

The surface area of the right prism = 2B ×Ph

[tex]\rm 2112 = 2\times 352+Ph\\\rm 2112 \div 704 = Ph\\[/tex]

h= 3/p ft

The height of the right prism of the surface area given as 2112 square feet is thrice the inverse of the perimeter.

Answer:

$320

Step-by-step explanation:

First, we can find how many cars they washed.

At 8 hours, they washed 32 cars, and since you still have two hours worth of cars to find, you can divide 16 by 2, and you get 8.

So in total, they washed 40 cars.

Now, you can multiply 40 by $8.00, and you get $320.

Answer:

119meters

Step-by-step explanation:

We should use the Pythagorean Theorem to solve this problem.

a^2+ b^2=c^2

64^2+100^2=c^2

4096+10000=14096

c^2=14096

c=\sqrt{14096}

14096

And the root of 14096 is 118.726577.

So the Answer is About 119 meters, or 118.726577

Answer:

Solution given:

length[l]/base[b]=100m

wide [w]/perpendicular [p]=64m

distance of diagonal =hypotenuse [h]=?

By using Pythagoras law

h²=p²+b²

h²=64²+100²

h=√14096

h=118.72

=119m approx

So

the player run 119m.
