Question:

James has 14,500g of sand in his sandbox. He brings home another 7,400g of sand from the beach to add to his sandbox. How many kilograms of sand does James have in his sandbox now?

Answer:

The quantity of sandbox James has is 21.9kg

Step-by-step explanation:

Given

Initial quantity of sandbox = 14,500 g

Additional quantity = 7,400 g

Required

Total quantity of sandbox in kg

Tp get the total quantity of sandbox, we simply add in the initial and additional quantity of sandbox together;

This is represented mathematically as follows;

Total = Initial Quantity + Additional Quantity

Total = 14,500 g + 7,400 g

Total = 21,900 g

But the question says the answer should be in kg

1000 g is equivalent to 1 kg

21,900 g will be equivalent to [tex]\frac{21,900}{1,000} kg[/tex]

[tex]21,900g = \frac{21,900}{1,000} kg[/tex]

[tex]21,900g = 21.9 kg[/tex]

Hence, the quantity of sandbox James has is 21.9kg

Answer:

d) 10 800

Step-by-step explanation:

Um ângulo é considerado raso quando sua medida é exatamente 180 graus, visto que cada grau equivale a 60 minutos, para obter a medida de um ângulo raso em minutos basta multiplicar 180 por 60:

[tex]180 *60=10800\ minutos[/tex]

A resposta correta é d) 10 800.

Answer:

infinite soulutions

Step-by-step explanation:

m+7=3+m+4

m+7=m+3+4 (Combine Like Terms)

m+7=m+7

Step 2: Subtract m from both sides

m+7−m=m+7−m

7=7

Answer: 0 (thus, infinite solutions is the correct option)

Step-by-step explanation:

m+7= m+3+4

m-m= 3+4-7 (transposing m and 7)

0=0

Answer:

Step-by-step explanation:

This is a parallelogram

base = 11 in

Height = 9 in

Area of parallelogram = base * height

                                    = 99 square inches

Answer:

3/7 (b)

Step-by-step explanation:

If a combination is picked at random with each possible locker combination  being equally likely, the conditional probability P(B|A) is 3/7.

Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome.

Probability of event A = P(the first digit is an odd number) = 4/8

Given that event A has already occurred, we need to calculate the probability of the occurrence of probability B.

The total possible outcomes are 7 (out of 8 one is used up in event A).

Favorable outcomes are 3 (out of 4 one is used up in event A).

P(B|A) = 3/7

Answer: i will help you, but the picture isnt clear for me

Step-by-step explanation:

Median: The middle number in the data set when the

data set is written from least to greatest.

Since our data set is already written from least to greatest,

we can just look for the number that appears in the middle.

In this case, it would be 3.

Mode: The number that appears

most frequently in a data set.

Notice that the number 3 appears twice in the data set and no other

number appears more than once. So the mode is 3.

Range: The difference between the greatest number in

the data set and the least number in the data set.

Since the greatest number is 8 and the least number is 1,

the range of the data set will be 8 - 1 or 7.

Answer: x + 3x = 11

Step-by-step explanation:

Two cities A and B

Both cities receive 11 inches of rainfall in total

Amount of Rainfall in inches received by city A = x

Amount of Rainfall in inches received by city B = 3x

Therefore given the details above, total rainfall is best expressed using the equation ;

Rainfall in city A + Rainfall in city B = 11 inches

x + 3x = 11

Answer:

[tex]\alpha' = 81^{\circ}[/tex]

Step-by-step explanation:

Angle is periodical function, so that following condition is satisfied:

[tex]\alpha = n \cdot 360^{\circ}[/tex]

[tex]n = \frac{801^{\circ}}{360^{\circ}}[/tex]

[tex]n = 2.225[/tex]

The position of the coterminal angle is:

[tex]n' = 2.225 - 2[/tex]

[tex]n' = 0.225[/tex]

[tex]\alpha' = n' \cdot 360^{\circ}[/tex]

[tex]\alpha' = (0.225)\cdot (360^{\circ})[/tex]

[tex]\alpha' = 81^{\circ}[/tex]

Answer:

Step-by-step explanation:

[tex]y-\frac{4x^5}{x^{2}-xy }[/tex] find common denominator and rewrite 1st  part as a fraction

[tex]\frac{y(x^{2}-xy) }{x^{2}-xy }[/tex] [tex]-\frac{4x^5}{x^{2} -xy}[/tex]

[tex]\frac{x^{2}y - xy^2 -4x^5 }{x^{2} -xy}[/tex]

[tex]\frac{x(xy-y^2-4x^4}{x(x-y)}[/tex]

[tex]\frac{xy-y^{2}-4x^4 }{x-y}[/tex]

The expression [tex]y -\frac{4x^5}{x^2 - xy}[/tex] can be simplified as   [tex]\frac{yx - y^2-4x^4}{x-y}[/tex]or  [tex]y -\frac{4x^4}{x - y}[/tex].

Fractions are numbers which has two parts, numerator and the denominator and is of the form p/q. Here, the number on the top p is called the numerator and the one on the bottom q is called the denominator.

Fractions can also be expressed and decimals and the reverse can also be applied.

Given expression is a mixed expression. We have to first change it into fractions and then have to simplify the complex fractions.

Given expression is [tex]y -\frac{4x^5}{x^2 - xy}[/tex].

First do the cross multiplication.

[tex]y -\frac{4x^5}{x^2 - xy}[/tex] = [tex]\frac{[y(x^2 - xy)]-4x^5}{x^2-xy}[/tex]

               =  [tex]\frac{(yx^2 - xy^2)-4x^5}{x^2-xy}[/tex]

               =  [tex]\frac{x(yx - y^2-4x^4)}{x(x-y)}[/tex]

               =  [tex]\frac{yx - y^2-4x^4}{x-y}[/tex]

               =  [tex]\frac{y(x - y)-4x^4}{x-y}[/tex]

               =  [tex]y -\frac{4x^4}{x - y}[/tex]

Hence the mixed expression given as  [tex]y -\frac{4x^5}{x^2 - xy}[/tex] can be simplified as  [tex]\frac{yx - y^2-4x^4}{x-y}[/tex] or  [tex]y -\frac{4x^4}{x - y}[/tex].

Answer:

Each pound of walnuts cost $3.50 and each pound of chocolate chips cost $1.50

Step-by-step explanation:

Let the cost of one pound of walnuts = $w

and the cost of one pound of chocolate chips = $c

Cost of 12 pounds of walnuts and 2 pounds of chocolate chips = $45

12w + 2c = 45 ------(1)

Cost of 3 pounds of walnuts and 5 pounds of chocolate chips = $18

3w + 5c = 18 --------(2)

Multiply equation (2) by 4 then subtract it from equation (1)

(12w + 2c) - (12w + 20c) = 45 - 72

-18c = -27

c = [tex]\frac{27}{18}[/tex]

c = $1.5

Substitute c = 1.5 in equation (1),

12w + 2(1.5) = 45

12w = 45 - 3

w = [tex]\frac{42}{12}[/tex]

w = $3.5

Therefore, each pound of walnuts cost $3.5 and each pound of chocolate chips cost $1.5

Step-by-step explanation:

Answer: Clare earned $6806.53.

Step-by-step explanation:

The formula given to us is the formula for compounded interest.

You can substitute the values given in the first part of the problem into the equation to find B, the final amount:

[tex]B = p*(1+r)^t\\\\B = 5003 * (1 + 0.08)^4[/tex]

Note that 8% interest is expressed as 0.08 because it is a percentage of a whole number.

Now, use a calculator to raise 1.08 to the fourth degree to get this:

[tex]B = 5003 * 1.360488\\B = 6806.526[/tex]

As such, Clare earned $6806.53 in interest after 4 years.
