The percentage of the annual budget withheld for taxes is 36%.

A compulsory contribution to state revenue, levied by the government on workers' income and business profits or added to the cost of some goods, services, and transactions.

The total budget of Ralph

The total budget of Ralph is calculated as follows;

T = 1,750 + 3,260 + 3,500 + 4,332 + 6,652 + 4,880 + 15,000 + 3,448 + 18,380

T = $61,202

Total tax on Ralph's annual budget

Tax = 3,448 + 18,380

Tax = $21,828

The percentage of the annual budget withheld for taxes is calculated as follows;

[tex]=\dfrac{Tax}{Total\ Budget}\times 100[/tex]

[tex]=\dfrac{21.82}{61.20}\times 100[/tex]

Answer:

144

Step-by-step explanation:

-12 * -12 = 144

12² =144

but the question was not 12², but -12²

so the answer is -144

if the exercise was between (), so writen like this (-12)²

then you would need to do the - to the power of 2 as well

Answer:

11

Step-by-step explanation:

y^2 - x^2

y = 6, x = 5

6^2 - 5^2

When using exponets we multiply a number by itself as many times as the exponet says, so in this case we multiply 6 x 6 and 5 x 5

6 x 6 = 36  5 x 5 = 25

36 - 25 = 11

Answer:

The range of the data is the difference between the largest data value and the smallest data value.

Therefore, the ranges are:

Boys:  10 - 3 = 7

Girls:  9 - 5 = 4

So the boys have a larger range than the girls.

To calculate the mean, add up all the data values then divide by the number of values.

[tex]\textsf{Mean of Boys}=\dfrac{3+6+7+7+8+8+8+8+9+10}{10}=\dfrac{74}{10}=7.4[/tex]

[tex]\textsf{Mean of Girls}=\dfrac{5+6+6+6+7+7+7+8+8+9}{10}=\dfrac{69}{10}=6.9[/tex]

So the boys have a higher mean than the girls.

1. 60% can be written as 60/100, simplified as 3/5
2. 2/5 is 40/100, can be written as 40%
3. 1/3 is 33.33333...% -> 0.(3) [ infinite recurring decimals if i remember  correctly]
4. 250 here is the base (original number)
5. 48/100 can be written as 48% -> 0.48
6. base
7. percentage
8. 300
9. 24%
10. portion
11. (i dont know what this mean, next time write it more carefully)
12. percentage

Answer:

a) 8/11 x 5/3

b) It will be positive. When we have an even number of negatives, the result will be positive ( (-) + (-) = +).

Step-by-step explanation:

a) -8/11 / -3/5

1) -8/11 ÷ (-3/5)

Write the complex fraction as a division expression. Use parentheses because our second fraction is a negative.

2) 8/11 ÷ 3/5

When we have an even number of negatives, the result will be positive ( (-) + (-) = +).

3) 8/11 x 5/3

Dividing is the same as multiplying the second part of the fraction flipped.

4) 40/33

Multiply them: 8 x 5 / 11 x 3

Since the question wants you to write as a multiplication expression, this is the answer:

8/11 x 5/3.

= 4 × 10^2

= 6 × 10^3

= 2 × 10^6

= 4 × 10^-1

( to find the standard form just count the zeros. )

a)= 4×10^2

b)= 6×10^3

c)= 2×10^6

d)= 4×10^-1

Continuation

Isolate the absolute-value term:

2 |3x - 5| - 4 = 12

2 |3x - 5| = 8

|3x - 5| = 4

Recall the definition of absolute value:

[tex]|x| = \begin{cases}x & \text{if }x \ge0\\-x&\text{if }x<0\end{cases}[/tex]

We consider two cases:

• If 3x - 5 ≥ 0, then |3x - 5| = 3x - 5, and the equation resolves to

3x - 5 = 4

3x = 9

x = 3

• Otherwise, if 3x - 5 < 0, then |3x - 5| = -(3x - 5) = -3x + 5, hence

-3x + 5 = 4

-3x = -1

x = 1/3

Answer:

the surface are is 34.64

Step-by-step explanation:

Point x is located at ( 2,5)

When reflecting across the y axis the x value remains the same.

The reflection is at y -2, from -2 to the location of z (-5) is a difference of 3 units.

Add 3 to the reflection line -2 + 3 = 1 , the new y value would be 1.

the new location would be (2,1)

Hey there!

2x + 3x = 20 + x

5x = 20 + x

20 + x = 5x

SUBTRACT x to BOTH SIDES

5x - x = 20x + x - x

5x - 1x = 20x + 1x - 1x

SIMPLIFY IT!
4x = 20

DIVIDE 4 to BOTH SIDES

4x/4 = 20/4

SIMPLIFY IT!
x = 20/4

x = 5

Therefore, your answer is: x = 5

Good luck on your assignment & enjoy your day!

It is plus five, minus two (repeated)

The pattern is +5 then -2 alternatively .

A pattern is a repeated arrangement of numbers, shapes, colors and so on. The Pattern can be related to any type of event or object. If the set of numbers are related to each other in a specific rule, then the rule or manner is called a pattern. Sometimes, patterns are also known as a sequence.

According to question

7 12 10 15 13 .........

The pattern in the series is  

7+5 = 12

12-2 = 10

10+5=15

15-2= 13 .....................

Hence, the pattern is +5 then -2 alternatively .

Answer:

x = 4

Step-by-step explanation:

When you have a coefficent in front of a logarithm function, you can take the argument to the power of that coefficient. For example, the 3 in front of the logarithm can be brought into the argument, and you can take 'x' to the third power. You get:

[tex] log_{4}( {x}^{3} ) = log_{4}(32) + log_{4}(2) [/tex]

When you add logarithms, it is equivalent to multiplying their arguments:

[tex]log_{4}( {x}^{3} ) = log_{4}(32 \times 2) = log_{4}(64) [/tex]

Since both sides are log base 4, the arguments must equal each other:

[tex] {x}^{3} = 64[/tex]

[tex]x = \sqrt[3]{64} = 4[/tex]

here it is, this is ur answer x=4
