Answer:

81

Step-by-step explanation:

my friend theres nothing on the world that will say that 96 - 15 = 9x

because 96-15= 81 and 81 + 15 equals 96

Answer:

4

Step-by-step explanation:

Let the number = X

You have X^8 / X^5

When dividing two numbers with powers, Simplify the expression by subtracting the powers.

8-5=3

so X^8 / X^5 becomes x^3

Now you have x^3 = 64

To find x take the cubic root of 64:

X = ∛64

X = 4

The number is 4

Answer:

E.

Step-by-step explanation:

Translation: slide of the shape or figure, it does NOT change its shape, size, and form, count how many units the shape moves.

Reflection: flip of the shape, does NOT change its shape, size, and form, either can be flipped or reflected over the x or y axis.

Rotation: turn of the shape, does NOT change its shape, size, and form, either can be rotated counter clock wise left, (opposite of a clock direction), or clockwise, the direction a clock moves right. It can also be rotated 90° (1 turn), 180° (2 turns), 270° (3 turns) or 360° (4 turns). In highschool, you will get introduced to more degrees of rotation, this is just middle school level.

Step-by-step explanation:

You can solve this with kinematics or with energy.

Using kinematics, given:

v₀ = 600 m/s

v = 200 m/s

Δx = 0.05 m

Find: a

v² = v₀² + 2aΔx

(200 m/s)² = (600 m/s)² + 2a (0.05 m)

a = -3,200,000 m/s²

Given:

v₀ = 600 m/s

v = 0 m/s

a = -3,200,000 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (600 m/s)² + 2(-3,200,000 m/s²) Δx

Δx = 0.05625 m

So the bullet needs to travel an additional 0.00625 m, or 0.625 cm.

Using energy, the work done on the bullet equals the change in kinetic energy.

ΔKE = W

½ mv² − ½ mv₀² = Fd

½ m (200 m/s)² − ½ m (600 m/s)² = F (0.05 m)

(-160,000 m²/s²) m = F (0.05 m)

F/m = -3,200,000 m/s²

½ mv² − ½ mv₀² = Fd

½ v² − ½ v₀² = (F/m) d

½ (0 m/s)² − ½ (600 m/s)² = (-3,200,000 m/s²) d

d = 0.05625 m

Answer:

60 millimeters

Step-by-step explanation:

15(4)= 60

Answer:

15+15+15+15=60

Step-by-step explanation:

another way and it's quicker is 15*4

well, 26+6 is 32, so divide that by 3 and you'd get 10.67, making daniel 32 by that time and his son being 10 years old

its simple math really, also, i hope this helps you ^-^

Answer:

3t2 and -2t2. and 6 and 12

Answer:

B

Step-by-step explanation:

Solution,

here,

slope(m)=-5

passing point;(-1 , -8)=(x1 , y1)

Using the formula:y-y1=m(x-x1)

or,y-(-8)= -5[x-(-1)]

or,y+8=-5x-5

.°.y= -5x-13

Answer:

D

Step-by-step explanation:

The number expression 5⁻¹⁵ rewritten using a positive exponent as -5¹⁵ option (A) -5¹⁵ is correct.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The number expression is:

= 5⁻¹⁵

By the property of the integer exponent we can write the above number exponent as follows:

= (5¹⁵)(-1)¹⁵

(-1)¹⁵ = -1   (because 15 is the odd number)

= -5¹⁵

Thus, the number expression 5⁻¹⁵ rewritten using a positive exponent as -5¹⁵ option (A) -5¹⁵ is correct.

Answer:

8 more men are needed to complete the job

Step-by-step explanation:

Proportions

This problem can be solved by step-by-step reasoning applying proportions:

The above statement stands because the fewer hours of work, the more time the job needs to be completed. Let's continue.

The same reasoning applies here, fewer men=more days.

Now for the second condition. Increase the hours/day:

More hours/day=less days to complete the job

We know this last time is 12 days, thus:

[tex]\displaystyle 12=\frac{14*9*16}{7*x}[/tex]

Solving for x:

[tex]\displaystyle x=\frac{14*9*16}{7*12}=\frac{2016}{84}=24[/tex]

24 men are needed now, this is an increase of 24-16=8 more men

8 more men are needed to complete the job

Apex

Step-by-step explanation:

1.

Radius of of the table cloth = diameter/2 = 30/2 = 15 inches

Area of the table cloth

[tex] A = \pi r^2 \\\\

= \pi (30)^2 \\\\

= \pi\times 900\\\\

= 900\pi [/tex]

Area of the table cloth [tex] = 900\pi\: inches^2 [/tex]

2.

Radius of circular garden = 3 m

Area of circular garden

[tex] A = \pi r^2 \\\\

= \pi (3)^2 \\\\

=\pi\times 9\\\\

=9\pi [/tex]

Area of circular garden [tex] =9\pi\: m^2 [/tex]
