find the equation of the line that passes through points A and B

Answer:

a = 11

b = 33

Step-by-step explanation:

Given :

Total fossil found = 33

Let :

Number of plant fossil = b

Number of animal fossil = a

a + b = 33

Plant fossil = 2 times number of animal fossil

b = 2a

Put b = 2a

a + 2a = 33

3a = 33

Divide both sides by 3

3a/ 3 = 33/3

a = 11

a + b = 33

11 + b = 33

b = 33 - 11

b = 22

Options are given

Answer:

4(1.5 * 16.50) + (1.5 * 9.60)

$113.40

Step-by-step explanation:

Last year:

Cost of full page ad = $16.50

Cost of half page ad = $9.60

50% increase in ad price this year :

Price, this year :

Full page = 1.50 * 16. 50 = $24.75

Half page = 1.50 * $9.60 = $14.4

Expression :

4(1.5 * 16.50) + (1.5 * 9.60)

Cost of a 4 and 1/2 page ad :

Full page = 4 * $24.75 = $99

Half page = 1 * $14.4 = $14.40

Total cost = $(99 + 14.40) = $113.40

Answer:

D) 11,13,22

Step-by-step explanation:

If 3y>27, then y>9. Therefore, D is the correct answer (C is not correct BTW because 9 isn't included in the inequality).

Solution :

It is given that the Precision Scientific Instrument company Manufactures thermometers that provide readings at 0 degree Celsius for the freezing point of water.

A quality control analyst examines the thermometers which provide readings in the bottom of 4%.

Using the standard normal table, we get

P(z < z) = 4%

P(z < z) = 0.04

See the probability of 0.04 in the standard normal corresponding to the z-value is = -1.75

Therefore,

P(z < -1.75) = 0.04

z = -1.75

So the temperature reading that separates the bottom of 4% from the other thermometers is - 1.75°C

Therefore correct option is (D). -1.75

Answer:

C=2πr

C=2π(1.9) cm

C=11.94 cm

Step-by-step explanation:

radius of a circle (r)=1.9 cm

Circumference of a circle (C)=?

We know that,

C=2πr

C=2π(1.9) cm

C=11.94 cm

So, the circumference of the circle is 11.94 cm.

Answer: 121

11^2 = 11 x 11 = 121

Answer:

121

Step-by-step explanation:

To square a number, we have to multiply the number by itself. This means we'll multiply 11 by 11.

11 · 11 = 121

So, 11² = 121.

I hope this helps :)

Answer: There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.

AB = 13200 miles

AO = 4000 miles

OB = 4000 miles

Let us assume CB = x

Then

(x + 4000)^2 = (13200)^2 + (4000)^2

x = sqrt(13200^2 + 4000^2) - 4000

= 13793 - 4000

= 9793 miles.

From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.

Answer:

13 quarts

Step-by-step explanation:

Remember this:

1 mug = 16 oz

1 quart = 32 oz

Find total quarts of coffee.

Setup proportion and solve for x ounces:

[tex]\frac{1 mug}{16 oz} =\frac{26 mugs}{xoz}\\\\x oz=16(26)=416 oz[/tex]

Setup another proportion to solve for x quarts and also use the 416 oz.

[tex]\frac{32oz}{1 qt} =\frac{416oz}{xqt} \\x=\frac{416}{32} = 13 qt[/tex]

Answer:

A

$10

Step-by-step explanation:

15% of $65 is 9.75

so $10 would cover the given amount

We want to see which card can cover completely the cost of a bat after a discount is applied. We will see that the correct options are:

D and E.

The baseball bat is originally sold for $65.

It has a discount of a 15%, then the new price is given by:

P = $65*(1 - 15%/100%) = $65*(1 - 0.15) = $65*0.85 = $55.25

So the gift cards that cover the whole cost of the discounted bat are these ones with a value equal or larger than $55.25

The correct options are:

D: $60

E: $80

With these two you could pay the complete cost of the discounted bat.

Answer: 197.82mm³

Step-by-step explanation:

Volume of a cylinder = πr²h

where,

π = 3.14

r = Diameter/2 = 6mm/2 = 3mm

h = 7mm

Volume = πr²h

= 3.14 × 3² × 7

= 3.14 × 9 × 7

= 197.82mm³

The volume of the cylinder is 197.82mm³

Answer:

4026

Step-by-step explanation:

Remember PEMDAS:

P - parenthesis

E - exponents

MD - Multiplication and Division (Left to Right)

AS - Addition and Subtraction (Left to Right)

------------------------

Start off by doing the parenthesis (7.1 x 10-5)

We must perform multiplication first so 7.1 x 10 is 71. From there you subtract 5 so 71 - 5 is 66!

So far we have: 66(6.7 x 10-6)

But we aren't done yet!

You must solve (6.7 x 10-6)

Same goes here, multiplication is done first so we would do 6.7 x 10 which is 67. Next, 67-6 which is 61.

We now have (66)(61)

When there is no sign of multiplication or division and the numbers are next to each other like this, you perform multiplication. So, 66x61 is 4026.

Thus, the answer is 4026!

Answer:

-2 1/4

converting the fraction to decimals

-2 2/5 = -2.4

-2.1 = -2 1/10

-2 1/4 = -2.25

this is between -2.1 and -2.4 on the number line

Step-by-step explanation:

to determine which number is between the numbers specified, convert to fractions

-2 2/5 = -2.4

-2.1 = -2 1/10

-2 1/4 = -2.25

3/10 = -0.3

this is less than -2.1

-21/2 = -2.5

this is greater than -21/4

-15/6 = -1.83

this is less than -2.1

it is only, -21/4 that is between the numbers
