Square of any real number cannot be negative because - * - = + so this equation has no solutions

Answer:

-31/4

Step-by-step explanation:

[tex]\frac{1}{2} ^{2}[/tex] is actually just (1/2)(1/2) and that equals 1/4

2 - (2/3) you can simplify to (6/3) - (2/3). that equals 4/3

now put it together!

(1/4) - 6(4/3)

(1/4) - (24/3) --------> (which simplifies to 8)

1/4 - 8 ----> (now you have to simplify this to match 1/4 denominator)

(1/4) - (32/4)

-31/4

Answer:

the area of the circle is 3,523.86

Step-by-step explanation:

We want to find the moon's gravitational acceleration.

With the given information, we will see that the gravitational acceleration on the moon is: g = 1.625 m/s^2

We know that in a place with a gravitation acceleration g, if you drop something from a height H, the position equation of that object will be given by:

p(t) = (-g/2)*t^2 + H

In this case, we know that a feather falls 81.25cm in one second.

First, we can define H = 0 (because we can put the zero of the position where we want to)

Then if after one second the feather falls 81.25cm = 0.8125 meters, we need to solve:

p(1s) = -0.8125 m = (-g/2)*(1s)^2

Where the negative sign comes because the feather "falls" and we define the negative position as below.

Also notice that we did a change of units from centimeters to meters, by knowing that:

100cm = 1m

then:

81.25cm = 0.8125m

Now we just need to solve:

-0.8125 m = (-g/2)*(1s)^2

0.8125 m = (g/2)*(1s)^2

2*0.8125 m = (g)*1s^2

1.625 m = g*1s^2

(1.625 m)/(1 s^2) = g

We then can conclude that the moon's gravitational acceleration is:

g = 1.625 m/s^2

Answer:

y = 2/5x - 5

Step-by-step explanation:

(-10,-9) and (10,-1)

Slope: (-1 - - 9) / ( 10 - - 10)

Slope = 8/20 = 2/5

b = -9 - (2/5(10)

b = -5

The equation of the line that passes through the point (−10,−9) and (10,-1) is; y = 2/5x - 5

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Where x₁ - x coordinate, y₁ - y coordinate, m - slope

Slope: (-1 - - 9) / ( 10 - - 10)

m = Slope = 8/20 = 2/5

Now intercept;

b = -9 - (2/5(10)

b = -5

Now Write the equation as

y = 2/5x - 5

Hence, the equation of the line that passes through the point (−10,−9) and (10,-1) is; y = 2/5x - 5

Answer:

=15

Step-by-step explanation:

45-x% *45=38.25

(-45) x/100=38.5-45

(-45)x/100=(-6.75)

x=6.75 * 100/45

=15

The percent of the discount is 15.

It is required to find the percent of the discount.

A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.

Given:

Let the discount percent be x%

When the price of $45 is reduced by x%, we get $38.25.

So,

45 − x % ∗ 45 = 38.25

− 45 x /100 = 38.25 − 45

− 45 x /100 = − 6.75

x = 6.75 ∗ 100 /45

x= 15

Therefore, the percent of the discount is 15.

Using the subtraction operation, the number of purple bags is 3 more than the number of yellow bags.

Amount of each color available :

Number of Purple bags :

Amount of color required per bag × Amount of purple color

Number of purple bags = [tex]\frac{3}{16} \times 64 = 12[/tex]

Number of Yellow bags :

Amount of color required per bag × Amount of Yellow color

Number of yellow bags = [tex]\frac{3}{16} \times 48 = 9[/tex]

Now we find the difference between the number of Purple and Yellow bags :

Number of purple bags - Number of yellow bags

Difference = 12 - 9 = 3 bags

Therefore, there are 3 more purple bags than Yellow bags.

Step-by-step explanation:

Treat it like a two-step equation:

Add 4 on both sides: 1/3b - 4 (+4) ≤ 4​ (+4)

1/3b ≤ 8

Multiply 3 on both sides (3)1/3b ≤ 8(3)

Answer:

1/2

Step-by-step explanation:

Slope is the rise over the run.  This means the difference in the y values over the difference in the x values.

The two points on the graph are (2,-2) and ( -6, -6 ).

The difference in the y values is a total of 4 units.

The difference in the x values is a total of 8 units.

The slope would then be 4/8 which simplifies to 1/2.

The line slants upward from left to right so the slope is positive.

Answer is 352 metres

The cloud is moving at a constant velocity. This means that we can find the velocity of the cloud by dividing the distance it moved by time:-

[tex]v = \frac{d}{t} [/tex]

Where "v" is velocity, "d" is distance and "t" is time.

The cloud moved 7920 metres in 22.5 minutes, so :-

[tex]v = \frac{7920 \: m}{22.5 \: min} [/tex]

[tex]v = 352 \: m/min[/tex]

Therefore, the cloud's velocity was 352 m/min.

division property of equality

Step-by-step explanation:

First in order to solve we must learn the properties of equality:

Addition property of Inequality:

If a > b , then a + c > b + c

substraction property of inequality

If a > b , then a - c > b - c

Multiplication property of inequality

If a > b , then a * c > b * c (if c > 0)

Division property of inequality

If a > b , then a / c > b / c (if c > 0)

Step 3: 2x>10

Step 4: x>5

When we divide by 2x/2 and 10/2 we get x>5 so we must use the division property of equality

Answer: 7 miles

Step-by-step explanation:

To get the length of the route use the expression for speed,

Distance = Speed × Time

Length of the route is 7 miles.

It's given in the question,

Speed of Tomas and Tasha initially = 3.5 mph

Therefore, distance travelled by both with the speed of 2 mph one way will be,

Distance = 3.5t [Here, t = time ]

Speed of both while coming back = 2 mph

And the time taken = t + (1 hour 30 minutes)

= (t + 1.5) hours

Therefore, distance travelled while coming back = Speed × Time

= 2(t + 1.5)

Since, length of the route is same both ways,

3.5t = 2(t + 1.5)

3.5t = 2t + 3

3.5t - 2t = 3

1.5t = 3

t = 2 hours

Now substitute the value of t in the expression to get the distance of the route,

Distance = 3.5t

= 3.5 × 2

= 7 miles

Therefore, route was 7 miles long.

Step-by-step explanation:

To find the cost per every square inch, divide the total cost of the pizza by the inches of the pizza. The pizza is 20 square inches and costs $15.99. The cost for every inch of pizza would be $0.7995, but you can just round that to $0.80 ($15.99/20 = $0.7995).
