Evaluate the expression 10 + ( 8 - 4) 2 divided by 2
A.10
B. 9
C.1
D.18

Answer:

356.05 cm³

Step-by-step explanation:

We are looking for the volume. The formula is density = mass / volume.

If we plug in our numbers, our formula would be 2.76 = 982.7 / V.

Multiply both sides by V and your formula would be (V) 2.76 = 982.7.

Divide both sides by 2.76 and you would get V = 356.05.

The volume of the given large emerald is required.

The volume of the given large emerald that was discovered in the mine was 356.05 cm³. The calculations to find this value is shown below.

m = Mass of object = 982.7 grams

[tex]\rho[/tex] = Density of the material the object is made of = 2.76 grams over centimeters cubed

The relation between mass, volume and density is given by

[tex]V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{982.7}{2.76}\\\Rightarrow V=356.05072\approx 356.05\ \text{cm}^3[/tex]

Step-by-step explanation:

X=5 and 3

Answer: a. x=3 or 5

Step-by-step explanation:

x^2-8x+15=0

When factoring this equation we need to find 2 numbers that multiply to get positive (15) and add to get negative (-8)

So -3 and -5 fit this description because -3+-5=-8 and -3*-5=15

(x-3)(x-5)=0

Solve for values of x to get x=3 and x=5

so X=3 or 5

Answer:

936

Step-by-step explanation:

Because 12%of 2600= 312

or 0.12×2600=312 for the first year

so multiply by 3 to get interest for 3 years

312 × 3 =936

Step-by-step explanation:

use pythagorean theorum (oof my spelling)

16^2 + 12^2 = 400

square root of 400 is 20

lol :))

Answer:

c=20

Step-by-step explanation:

the answer above me said it was 20 and i got it right

1^6 = 1

11^2 = 11 x 11

11 x 11 = 121

121 + 1 = 122

Answer:

If the numbers were the same, they'd both be 61

So, try 60 and 62.

x + x+2 = 122

2x = 120

x = 60

Hope that helps!

Answer:

60 and 62

Step-by-step explanation:

To find the answer we need to set up our problem.

For the two consecutive even integers we can call them x and x+2, as adding 2 to x will give us the next even number.

Then we form our equation:

x+x+2=122

Since we have two x we can combine them into a single term

2x+2=122

We then subtract 2 from both sides

2x=120

Divide by 2

x=60

Find the second number by inserting it into

x+2

60+2=62

Answer:

It is C.

Step-by-step explanation:

So,A triangle is equal to 180 and you would add up the numbers you already have which equal 145.180-145= 35° and thats why the last letter would be 35° in your answer and be correct which would be that m<F=35° is the same as ABC in the last letter. Since,<B is the second letter in ABC and so is <E in DEF and have the same degree that would be the same as well so I hope that helps:)

Answer:

c

Step-by-step explanation:

the angles in a triangle have to add up to 180°

65 + 80 = 145

180-145 = 35

the missing angle is 35°

choice c matches because it has 2 of the same angle measures, which means they all have to be the same

Answer:

Part A) About 3 it represents the amount of matches won with 0 months of practic3

Part B) points used = (2,8) (5,12)

equation in slope intercept form: y=[tex]\frac{4}{3}x +3[/tex]

games won after 13 months = about 20

Step-by-step explanation:

Part B work:

points used = (2,8) (5,12)

[tex]\frac{ y_{1} -y_{2} }{x_{1}- x_{2} }[/tex] = slope equation

[tex]\frac{12-8}{5-2}[/tex]= slope equation filled in

[tex]\frac{4}{3}[/tex]=slope

So the equation in slope intercept form:

y=mx+b

mx = slope

b = y intercept

So the equation is:

y=[tex]\frac{4}{3}x +3[/tex]

Games won after 13 months:

months = x

y=[tex]\frac{4}{3}[/tex](13) + 3

4/3 x 13 = 17.3

y=17.3+3=20.3

Answer:

$31.80

Step-by-step explanation:

The ball will cost 100% of its price plus 6% of its price for a total of 106%.

To use percentages as a factor and multiply, they must be divide by 100, making the multiplication factor version of 106% 1.06.

Multiply the cost of the ball by your multiplication factor:

30 x 1.06 = 31.8

Money is written to two decimal places, making your answer $31.80

Answer:

$31.80

Step-by-step explanation:

First, find how much the sales tax is

$30 × 6%

Convert the percentage into a decimal

30 × 0.06

1.8

$1.80

Add the sales tax to the original cost

$30 + $1.80

$31.80
