Answer:

Each boy will get <u>25</u> marbles.

Step-by-step explanation:

Given:

William has 3 jars of marbles to share equally with his brother the first jar holds 12 marbles the second jar holds 21 marbles the last jar holds 17 marbles.

Now, to write an expression using parentheses to find number of marbles each boy get.

Let the number of marbles each boy get be $x.$

Total number of boys = 2.

Number of marbles first jar holds = 12.

Second jar holds = 21.

And third jar holds = 17.

As given, William shares marbles equally with his brother.

Now, we write the expression to find the number of marbles each boy get:

$x=\frac{(12+21+17)}{2}$

$x=\frac{12}{2} +\frac{21}{2} +\frac{17}{2}$

$x=6+10.5+8.5$

$x=25.$

Therefore, each boy will get 25 marbles.

The graph of a square root function has a domain of (0, infinity) and range of [1, infinty). In two or more complete sentences,

KIM [24]

We know that Range of a function is the values that a function can take in its domain The range interval of a function is between the minimum value and the maximum value that the function can take so in this problem The range of the function is the interval-------> [1, ∞)

That means The minimum value of the function in the domain is The maximum value of the function in the domain is infinite

Can someone do this for me I was busy helping around for my mom and myself please it's due today!!!!!!

Answer:

first discount for Q7 is $54.3915

the next discount is $48.95235

for Q8 is

Step-by-step explanation:

you are a very nice person for helping your mom. good luck for this!

ok let's work on question 7 first.

$63.99 is the cost of a skateboard.

15% of 63.99 = 10% + 5%

10% of 63.99 = 6.399 (move the decimal one place to the left)

5% of 63.99 = 1/2 of 6.399

1/2 x 6.399 = 3.1995

6.399 + 3.1995 = 9.5985

ok, so that's 15% of 63.99

now we need to take away 9.5985 from 63.99

63.99 - 9.5985 = 54.3915

the discount price of the skateboard is $54.3915

a further 10% is $5.43915

so take off that from the discount,

54.3915 - 5.43915 = 48.95235

the final price is $48.95235

QUESTION 8

shop A = 6.95 x 40

6.95 x 40 = $278

shop B = 20% of 325

20/100 * 325 = 65

325 - 65 = 260

therefore, shop B is cheaper.

hope this helped, good luck!

An isosceles triangle whose equal sides measure 8 and whose altitude drawn to the base measures 8

viva [34]

The question is incomplete, the complete question is here

Find the measures of the angles of an isosceles triangle whose equal sides measure 8 and whose altitude drawn to the base measures 4

Answer:

The measures of the angles of the isosceles triangle are 30°, 30° and 120°

Step-by-step explanation:

In a triangle whose sides a, b, c and angles A, B and C, where a is opposite to ∠A, b is opposite to ∠B, and c is opposite to ∠C, the given is

a = c
m∠A = m∠C

The height from ∠B to side b is 4 units

That means the length of the height is half the length of each equal sides, then there is a right triangle its hypotenuse is 8 and the side opposite to the base angle is 4, so we can find the measure of the base angle by using the rule sin(base angle) = $\frac{altitude}{a}$

∵ The base angles are ∠A and ∠C

∵ a = c = 8

∵ The altitude to b is 4

∵ $sin(A)=\frac{4}{8}=\frac{1}{2}$

- By using $sin^{-1}$

∴ m∠A = $sin^{-1}(\frac{1}{2})$

∴ m∠A = 30°

∵ m∠A = m∠C

∴ m∠C = 30°

Use the rule of the sum of the measures of the interior angle of a Δ is 180° to find m∠B

∵ m∠A + m∠C + m∠B = 180

∵ m∠A = m∠C = 30°

∴ 30° + 30° + m∠B = 180°

∴ 60 + m∠B = 180

- Subtract 60 from both sides

∴ m∠B = 120°

The measures of the angles of the isosceles triangle are 30°, 30° and 120°
