Answer:

311

lol

Step-by-step explanation:

Answer:

Easy! It’s 311!

Step-by-step explanation:

1. Write down 356 - 45.

2. What is 6 - 5? It’s 1.....

3. What is 5 - 4? It’s 1......

4. Put the 3 in the hundreds place so your answer should be 311.

Explanation:

The negative exponent means we apply the reciprocal to get the exponent to be positive.

The rule is (a/b)^(-c) = (b/a)^c

That means (1/4)^(-3) = (4/1)^3 = 64 which is a whole number.

Something like 2^(-3) = 1/(2^3) = 1/8 = 0.125 isn't a whole number, so we can cross that off the list. The same goes for choices A and C as well.

Answer:

B

Step-by-step explanation:

1/1 ÷ (1/4)³ = 1 x 4³ = 64

Answer:

mass=640/1000kg

=0.64kg

acceleration =10m/s^2

now,

force=mass*acceleration

=0.64*10

=6.4newton

Answer:

1 13/16 gallons

1.8125 gallons

Step-by-step explanation:

convert the measures that are not in gallons to gallon

1 pint = 1/8 gallon

4 x 1/8 = 1/2

1 cup =1/16 gallon

5 x 1/16 = 5/16

0.3125

1 quart = 1/4

1/4 x 2 = 1/2

Add these figures togehter

1/2 + 5/16 + 1/2 + 1/2 = 29 / 16 = 1 13/16 gallons

Answer:

8 1/3 meters

Step-by-step explanation:

set up a proportion of corresponding sides:

TE/AY = JT/DY

25/AY = 18/6

cross-multiply:

18AY = 150

AY = 150/18 which is 8 1/3

Answer:

[tex]y=-\frac{1}{2} x+4[/tex]

Step-by-step explanation:

The equation of a straight line in slope intercept form is given by:

y = mx + c;

where y, x are variables, m is the slope of the line and c is the y intercept (that is value of y when x is 0).

The equation of a line passing through point ([tex]x_1,y_1[/tex]) with a slope of -1/2 is given by:

[tex]y-y_1=m(x-x_1)[/tex]

Given that the line passes through the point (-10,9) and has a slope of -1/2. Hence the equation of the line is:

[tex]y-9=-\frac{1}{2}(x-(-10)) \\\\y-9=-\frac{1}{2} (x+10)\\\\y=-\frac{1}{2} x-5+9\\\\y=-\frac{1}{2} x+4[/tex]

Answer:

Equation: 180 = 127.50 + 3.5x

Angle 1: 135.45°

Angle 2: 44.55°

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

9/4x + 101.7 + 1 1/4x +25.8 = 180

Change the mixed number to an improper fraction

9/4x + 101.7 + 5/4x +25.8 = 180

Combine like terms

14/4x +127.5 = 180

Subtract 127.5 from each side

14/4x = 180-127.5

14/4x = 52.5

Multiply each side by 4/14 to isolate x

x =52.5 * 4/14

x = 15

Angle 1 = 9/4x +101.7 = 9/4*15 + 101.7 = 33.75+101.7=135.45

Angle 2 = 1 1/4x +25.8 = 5/4 (15) +25.8 =18.75+25.8=44.55

Answer:

Step-by-step explanation:

6x-10=20

6x=20+10

x=30/6

x=5

to prove 6x-10=30

substitute the value of x

6x-10

6*5-10

30-10

20

20=20  hence proved.

Answer: B. 1

Step-by-step explanation: A common factor is something that two or more numbers have in common. It is 1 because you multiply 1 by 1 to get 1, and 1 by 2 to get 2.

(1 by 1) = 1

(2 by 1) = 2

These two numbers have the number 1 in common because both 1 and 2 can only be multiplied by 1 and itself to get the number. (That is also what you call prime numbers.)

Answer:

n = 12

Step-by-step explanation:

Given

[tex]\frac{n}{6}[/tex] = [tex]\frac{4}{2}[/tex] = 2 ( multiply both sides by 6 )

n = 12

=>10³

5 × 10³ × 10³ = 5 × 10⁶

The 10³ or 1000 is multiplied by the expression 5x 10^3 is equivalent to the expression 5 x 10^6 option third is correct.

The distributive property is the property that expresses the distributive law of algebraic multiplication for example we can write a(c+b)  in the form of (ac+bc).

We have an expression:

= 5×10³

We have to make the above expression equivalent to the [tex]5\times 10^6[/tex]

Let's suppose the number is x.

Now according to the question:

[tex]\rm (5\times10^3)\times x = 5\times 10^6[/tex]

[tex]\rm x = \frac{5\times 10^6}{(5\times10^3)}[/tex]    (divide by 5×10³ on both sides)

x = 10³           (after simplification)

x = 1000

Thus, the 10³ or 1000 is multiplied by the expression 5x 10^3 is equivalent to the expression 5 x 10^6 option third is correct.

Answer:

[tex]{ \boxed{a = 3.75}}[/tex]

[tex]{ \boxed{b = 16}}[/tex]

Step-by-step explanation:

[tex](4.46 \times {10}^{9} ) \times (8.4 \times {10}^{6} ) \\ = 3.7464 \times {10}^{16} \: breaths[/tex]

Answer:

Step-by-step explanation:

y = ax + b

The trick is to solve for a.

y = 505

x = 8

b = 25

505 = a*8 + 25                Subtract 25 from both sides

-25             -25

480 = 8a

a = 60

What this means is that for each one of the 8 months, he added 60 dollars into his account

The equation is y = 60*x + 25
