frazers scores 75% in a spelling test with 40 questions, how many did he get right?

Answer:

D. 30.96 in²

Step-by-step explanation:

The area of the shaded region = area of the the square - area of the circle

= (s²) - (πr²)

s = 12 in

r = radius of circle = ½ of 12 in = 6 in

π = 3.14

Plug in the values into the equation

Area of the shaded region = (12²) - (3.14*6²)

= 144 - 113.04

= 30.96 in²

Answer:

E = mc^2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

Step-by-step explanation:

E = energy

m = mass

c = the speed of light

Answer:

E represents units of energy, m represents units of mass, and c2 is the speed of light squared,

Step-by-step explanation:

So energy = mass times speed squared

Answer:

66 is it

Step-by-step explanation:

easy just say 66

Answer:

yes

Step-by-step explanation:

Yes, △ ABC appears to be the same size and shape as △ XYZ by SAS similarity, and △ ABC can be mapped by translation and rotation, so option A is correct.

Simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes, it is represented by the symbol and consists of three connected vertices.

Given:

Right triangles ABC and XYZ. ABC has a shorter leg equal to 5 and a hypotenuse equal to 13,

The triangles ABC and XYZ are similar by SAS similarity, as,

AC = XZ = 5,

AB = YZ = 13

∠ ACB = ∠ XZY

When you translate and then rotate triangle ABC, you will get triangle XYZ.

Step-by-step explanation:

Step 1: Define Points

A (-6, 10)

B (-2, 7)

Step 2: Find slope m

And we have our final answer!

Answer:

[tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

To find the slope of the line, we use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when we are given the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].

When we plug the points A(-6,10) and B(-2,7) into the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], we get the equation [tex]\frac{7-10}{-2-(-6)}[/tex].

[tex]\frac{7-10}{-2-(-6)}\\= \frac{-3}{4}[/tex]

Therefore, the slope of the line is [tex]-\frac{3}{4}[/tex].

Answer:

4/3, or 1 1/3

Step-by-step explanation:

For a whole number, 1 is always the denominator. It would look like 4/1 x 3/8. Then you would multiply both the numerators and denominators. That would get you 12/8. Simplify it, to get 4/3. If you want to simplify it even more, you would get 1 1/3.

Answer:

21 cups of coffee

Step-by-step explanation:

So the coffee:tea is 3:2. We can put it as 3x+2x=35 as we know there are 35 drinks, do not know the exact number of coffee and tea, but know the ratio.

Now, x=7. So coffee is 3(7)=21 and tea is 2(7)=14.

Answer:

[tex](3,0)[/tex]

Step-by-step explanation:

The integer points which fall in the common region bounded by the lines are

[tex](0,2),(2,3),(3,0)[/tex]

Since, one of the points is [tex](2.22...,3.11....)[/tex] we round it to [tex](2,3)[/tex]

If we round up then the point will be [tex](3,4)[/tex] which does not fall in the bounded region.

Also [tex]x_1\geq 0[/tex] and [tex]x_2\geq 0[/tex] no negative values are considered.

Applying in the values in the LP problem [tex]Z=5x_1+x_2[/tex]

[tex]Z=5\times 0+2\\\Rightarrow Z=2[/tex]

[tex]Z=5\times 2+3\\\Rightarrow Z=13[/tex]

[tex]Z=5\times 3+0\\\Rightarrow Z=15[/tex]

So, the LP problem is maximum at point [tex](3,0)[/tex].

To find 5/12 divided by 2, we do keep change and flip

Therefore we keep 5/12 change the division sign and flip the 2

We will get

5/12 * 1/2, this would give us 5/24

Answer:

P(t) = 17.5 feet

Step-by-step explanation:

The position above the ground at a given  point in time can be represented by the quadratic function as follows:

[tex]P(t)=gt^2 + vot + Po[/tex]

Where,

Po is the initial position above the ground

If the ball was thrown  straight up at 40 ft/sec when it was 5 ft above the ground.

We need to find the height reached by the ball.

The equation will become :

[tex]P(t)=-32t^2 + 40t+ 5[/tex]

Firstly we find the time taken to reach its maximum height

Put, dP(t)/dt = 0

[tex]\dfrac{d(-32t^2+40t+5)}{dt}=0\\\\-64t+40=0\\\\t=0.625\ s[/tex]

Now put t = 0.625 in equation (1) as follows :

[tex]P(0.625)=-32(0.625)^2 + 40(0.625)+ 5\\\\=17.5\ \text{feet}[/tex]

So, it will go at a height of 17.5 feet.

Answer:

There are 60 green paper clips.

Step-by-step explanation:

if 2/3 of the box = 120 clips, then you can determine that 1/3 is 60, since 1/3 is half of 2/3. If 1/3 is 60, Since you already know that 2/3 is 120 clips, you add 60 to get 180 total clips, and 60 of them are green.

Answer:

60 Green Paper Clips

Step-by-step explanation:

120/2 = 60 (which would be 1/3)

Answer:

204.2 units

Step-by-step explanation:

Area of semicircle: 1/2(πr^2)

r = 5

1/2(π(5)^2)

94.2477796

Area of Rectangle: w * l

l = 11

w = 5(2)

11 * 5(2) = 11 * 10 = 110

Total:

110 + 94.2 = 204.2 units

Answer:

Step-by-step explanation:

total area = rectangle + semicircle

                = (11 x 10) + (1/2 x π 5²)

                = 110 + 39.27

                = 149.3

Answer:

[tex]\boxed {\boxed {\sf 2 \ significant \ figures}}[/tex]

Step-by-step explanation:

According to the "rules" of significant figures, all the zeroes to the right of the final non-zero number are not significant, unless there is a decimal point.

We are given the measurement:

84,000 kg

If there was a decimal point (84,000.0 kg), then there would be 5 significant figures.

Since there isn't a decimal point, all 3 zeroes to the right of the number 4 aren't significant. The 8 and 4 are significant, so there are 2 significant figures.
