Answer:

40

Step-by-step explanation:

divide 100 by 5 which equals 20 times that by 2

Answer:

40

Step-by-step explanation:

First we divide 100 by 5

100/5 = 20

Since there are 2/5, we multiply 20 by 2 to get our answer

[tex](3;-2)[/tex]

Step-by-step explanation:

Let's add together the two equations

[tex]I + II : x-8y +9x +8y = 19+11 \rightarrow 10x=30 \rightarrow x =3[/tex]

At this point I would recommend simply using the value of x in the firs equation to find y. [tex]3-8y=19 \rightarrow -8y=16 \rightarrow y=-2[/tex]

Or just multiply the first by 9 and subtract the second.

[tex]9\times I-II: 9x-72y-9x-8y=171-11 \rightarrow -80y=160 y=-2[/tex]

4,7

Step-by-step explanation:

17x+6=19x-2(being vertically opposite)

6+2=19x-17x

8=2x

x=8/2

x=4

10x-5=9+8x(being corresponding angle)

10x-8x=9+5

2x=14

x=14/2

Answer:

well first we need to see the total percent of sugar solution there is.

So first we need to add 50%+68%=118%/200%

so now 62%/100% needs translated to /200%.

We get 124%/200% Now 50%/100%=100%/200% 68%/100%=136%/200%

62% would be in a total of needed of like 7 ml of the 50% sugar solution i think let me know if i am wrong

Step-by-step explanation:

The 21603 base seven and 77 base ten are number bases

1. What base ten number does 21603 seven represent?

This is represented as:

[tex]21603_7[/tex]

To convert to base 10, we have:

[tex]21603_7 = 2 * 7^4 + 1 * 7^3 + 6 * 7^2 + 0 * 7^1 + 3 * 7^0[/tex]

Evaluate the sum and the exponents

[tex]21603_7 = 5442[/tex]

Hence, 21603 base seven represents 5442 in base ten

2. Express the number 77 ten in base number

This is represented as:

[tex]77_{10}[/tex]

To convert to a base number (say base 7), we have:

77/ 7 = 10 R 0

10/7 = 1 R 3

1/7 = 0 R 1

Hence, 77 base ten represents 130 in base seven

Answer: 15%

Step-by-step explanation:

have an wonderful Day!

The tax rate Tasha will pay on her investment income is 15%.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

Ordinary taxable income= $90,000

Capital gains= $12,000

Now,

The tax rate Tasha will pay on her investment income depends on her ordinary taxable income and the tax brackets for qualified dividends and long-term capital gains. Since Tasha’s ordinary taxable income is $90,000, she falls in the 15% tax bracket for her investment income.

Therefore, by the percentage the answer will be 15%.

Answer:

5 and 3 pints

Step-by-step explanation:

there are 4 pints in 1 cup.

23 pints is equal to 46 cups using the conversion factor 2 cups = 1 pint.

As, 2 cups = 1 pint.

Using the conversion factor 2 cups = 1 pint, convert 23 pints to cups.

So, to convert pints to cups, multiply the number of pints by 2 as

= 23 pints x 2 cups/pint

= 46 cups

Therefore, 23 pints is equal to 46 cups.

Answer: Axis of Symmetry at x=1

Step-by-step explanation:

Internet Definition: The axis of symmetry is the vertical line that goes through the vertex of a parabola so the left and right sides of the parabola are symmetric. To simplify, this line splits the graph of a quadratic equation into two mirror images.

So pretty much you see the "hill shape" on the graph... the highest part of the hill is the axis of symmetry so the axis of symmetry is at x=1

Here is the formula for compound interest:

CI = P(1 + r/n)^rt, where n is the number of times the interest is compounded in a year. In our case, since there is semi annual compounding, n = 2.

The rest of the formula can be filled out:

CI = 5000(1 + 0.018/2)^(5x2)

CI = 5000(1.009)^10

Please post the full question/picture ^-^

Step-by-step explanation:

I believe some part of the question is missing.

Answer:

The correct option is A....

Step-by-step explanation:

We have a table of x,y pairs. To compute the slope we can use any two pairs, say the first two, and plug them into our formula:

m = y2-y1 / x2-x1

m = 5-13/ 0-(-2)

m = -8/0+2

m = -8/2

m = -4

We can check this answer by using a different pair: Take the last two pairs.

m = -27-(-15)/ 8-5

m = -27+15/3

m = -12/3

m = -4

Thus the slope is -4

[tex]\frac{14}{15}[/tex]

Step-by-step explanation:

We require to create 2 equations with the repeating 3 after the decimal point.

let x = 0.93333333333 ( multiply both sides by 10 and 100 )

10x = 9.3333333333 → (1)

100x = 93.333333333 → (2)

Subtract (1) from (2) , eliminating the repeating decimal

90x = 84 ( divide both sides by 90 )

x = [tex]\frac{84}{90}[/tex] = [tex]\frac{14}{15}[/tex]

Thus

0.933333333333 = [tex]\frac{14}{15}[/tex]
