Jackson buys a new Shirt. The shirt is 25% off the original price. Jackson pays a total of $11.34 for the shirt, which includes a sales tax of 8%. What is the original price, in dollars, of the shirt?

1 yard = 3 feet.

Multiply the length of the truck by 3 to get total feet:

6 x 3 = 18 feet.

Subtract the length of the truck from the length of the parking space:

20 - 18 = 2 feet

1 foot = 12 inches.

Multiply 2 feet by 12:

2 x 12 = 24 inches longer.

Answer:

length of base is 10

Step-by-step explanation:

The area of the entire firgure is 1600 cm^2.  There are 4 equal sized pennants, so each pennant is 1600/4 = 400

the bottom pennant has area 400 and is triangular shaped.  the area of a triangle is 1/2 b h.  

A = 1/2 b h       given height is 80 and area is 400.  plug these values in

400 = 1/2 b (80)

400 = 40 b       divide both sides by 40

b = 10

Answer:

[tex]I=\frac{13xr}{1,200}[/tex]

Step-by-step explanation:

we know that

The simple interest formula is equal to

[tex]I=P(rt)[/tex]

where

I is the Simple interest Value

P is the Principal amount of money to be invested

r is the rate of interest  in decimal form

t is Number of Time Periods in years

in this problem we have

[tex]t=(13/12)\ years\\ P=\$x\\r=(r/100)[/tex]

substitute in the formula above

[tex]I=x(r/100)(13/12)[/tex]

[tex]I=\frac{13xr}{1,200}[/tex]

Final answer:

To calculate simple interest for x dollars at an rate of r percent over 13 months, convert r percent to a decimal and time to years, then use the formula I = x × (r/100) × (13/12). For example, $100 at 5% interest for 13 months would earn approximately $5.42 in simple interest.

Explanation:

The calculation of simple interest for a principal of x dollars at a rate of r percent over 13 months involves a few straight-forward steps. The formula for the simple interest is given by:

I = P × r × t

Where I represents interest, P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal form), and t is the time the money is invested or borrowed for, in years.

To convert the rate r percent to a decimal, divide by 100. Then, convert the time of 13 months to years by dividing by 12.

Thus, the simple interest formula for this question becomes:

I = x × (r/100) × (13/12)

For example, if you deposit $100 into a savings account with a simple interest rate of 5% for 13 months, the interest earned would be calculated as follows:

I = 100 × (5/100) × (13/12)

This results in:

I = 100 × 0.05 × 1.08333

I = $5.42 (approximately)

The simple interest earned, in this case, would be approximately $5.42.

Answer:

See below  

Step-by-step explanation:

14)

 14² =   8² + TV²

196 = 64  + TV²

TV² = 132

TV =√132 = √(4 × 33) = 2√33

sinA = TV/AT   = (2√33)/14 = √33/7

cosA = AV /AT = 8/14          = 2/7

tanA = TV/AV   = (2√33)/8  = √33)/4

sinT = AV/AT   = 8/14          = 4/7

cosT = TV/AT   = (2√33)/14 = √33/7

tanT = AV/TV   = 8/(2√33)   = (4√33)/33

16)

  6² = 3² + GT²

 36 = 9   + GT ²

GT² = 27

GT  = √27 = √(9 × 3) = 3√3

sinA = GT/AT  = (3√3)/6 = √3/2

cosA = AG/AT = 3/6        = ½

tanA = GT/AG = (3√3)/3 = √3

sinT = AG/AT = 3/6        = ½

cosT = GT/AT = (3√3)/6 = √3/2

tanT = AG/GT = 6/(3√3) = (2√3)/3

18)

 13² =   8² + TX²

169 = 64  + TX²

TX² = 105

TX  = √105

sinA = TX/AT  = (√105)/13

cosA = AX/AT = 8/13

tanA = TX/AX  = (√105)/8

sinT = AX/AT  = 8/13

cosT = TX/AT  = (√105)/13

tanT = AX/TX  = 8/(√105) = (8√105)/105

Step-by-step explanation:

QUESTION 1

The given logarithm is

[tex]\log_{243}(27)[/tex]

Let [tex]\log_{243}(27)=x[/tex].

We rewrite in exponential form to get;

[tex]27=243^x[/tex]

We rewrite both sides of the equation as an index number to base 3.

[tex]3^3=3^{5x}[/tex]

Since the bases are the same, we equate the exponents.

[tex]3=5x[/tex]

Divide both sides by 5.

[tex]x=\frac{3}{5}[/tex]

[tex]\therefore \log_{243}(27)=\frac{3}{5}[/tex]

QUESTION 2

The given logarithm is

[tex]\log_{25}(\frac{1}{5} )[/tex]

We rewrite both the base and the number as power to base 5.

[tex]\log_{5^2}(5^{-1})[/tex]

Recall that: [tex]\log_{a^q}(a^p)=\frac{p}{q} \log_a(a)=\frac{p}{q}[/tex]

We apply this property to obtain;

[tex]\log_{5^2}(5^{-1})=\frac{-1}{2}\log_5(5)=-\frac{1}{2}[/tex]

The correct answer would be A.

A.

Answer: option c

Step-by-step explanation:

By definition, you can calculate the slope of  line by applying the formula shown below:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Then:

You can see that in the option C the equation of the slope is applied correctly:

[tex]\frac{9-(-3)}{1-(-2)}[/tex]

Where:

[tex]y_2=9\\y_1=-3\\\\x_2=1\\x_1=-2[/tex]

Then, you obtain the following value of the slope of the line:

[tex]m=\frac{9-(-3)}{1-(-2)}=4[/tex]

Answer: Your correct answer should be C, [tex]\frac{(9 - (-3))}{(1 - (-2))}[/tex]

Step-by-step explanation:

Recall the slope equation is: (y2 - y1)/(x2 - x1) or [tex]\frac{(y2 - y1)}{(x2 - x1)}[/tex]. You need two points: point one (x1, y1) and point two (x2, y2).

* The first answer choice is flawed because not only is it in a different formula (xs are in the numerator instead of the denominator area), but it says 1 - 2 when it should be 1 - (-2) or 1 + 2.

* The second answer choice is flawed because it is in a different formula (this time, x1 - x2/y3 - y2) and 2 - 1 is suppose to be -2 - 1.

* The last answer is flawed because it should be -3 - (-) 11 and -2 - (-)4, or -3 + 11 and -2 + 4.

Note: If you had a negative operation and a negative number behind it, you can either formulate the equation like x - (-) y or drop the negative sign from said number and change the minus operation sign to the plus one (x + y).

The only answer choice that checks out and is not flawed is C.

Answer:

The correct answer option is P (both green) = 91 / 435

Step-by-step explanation:

We are given that in a jar containing 30 marbles, 10 are red, 6 are black and 14 are green.

Two marbles are drawn and the second one is drawn without returning the first marble and we are to find the probability of getting green marbles both time.

P (both green) = [tex] \frac { 1 4 } { 3 0 } \times \frac { 1 3 } { 2 9 } [/tex] = 91 / 435

in short, we simply split the total amount by the given ratio, so we'll split or divide 1020 by (15 + 2) and then distribute accordingly.

[tex]\bf \cfrac{petunias}{geraniums}\qquad 15:2\qquad \cfrac{15}{2}~\hspace{7em}\cfrac{15\cdot \frac{1020}{15+2}}{2\cdot \frac{1020}{15+2}}\implies \cfrac{15\cdot \frac{1020}{17}}{2\cdot \frac{1020}{17}} \\\\\\ \cfrac{15\cdot 60}{2\cdot 60}\implies \cfrac{900}{120}\implies \stackrel{petunias}{900}~~:~~\stackrel{geraniums}{120}[/tex]

The total number of geraniums in the greenhouse is 120. This was determined by calculating the value of each 'part' in the provided petunia to geranium ratio and then multiplying the number of geranium 'parts' by this value.

The question provides a ratio of petunias to geraniums in the greenhouse, which is 15:2. This is the same as saying for every 15 petunias, there are 2 geraniums. If you combine the parts of the ratio, you get a total of 17 parts (15 petunias + 2 geraniums). We know that the total number of flowers in the greenhouse is 1020.

Now, we'll figure out what each 'part' is equal to in the real world. To do that, we divide the total number of flowers by the total number of parts, so 1020 ÷ 17 = 60. This tells us each 'part' in our ratio is equal to 60 flowers.

From there, since we need to find the number of geraniums, we multiply the number of geranium 'parts' by the value of each 'part'. So, the number of geraniums in the greenhouse is 2 (The geranium 'parts') x 60 = 120 geraniums.

I hope I helped you.

By substituting a = π/2 and b = x into the trigonometric subtraction formula and considering that sin(π / 2) equals 1 and cos(π / 2) equals 0, we can verify the identity sin((π / 2) – x) = cos x

The question asks us to use the trigonometric subtraction formula for sine to verify the identity: sin((π / 2) – x) = cos x. From the trigonometric subtraction formulas, we know that sin(a - b) = sin a cos b - cos a sin b.

In this case, a = π/2 and b = x. Substituting these values into the formula, we ge: sin((π / 2) - x) = sin(π / 2) cos x - cos(π / 2) sin x.

Since sin(π / 2) equals 1 and cos(π / 2) equals 0 (from the Unit Circle in trigonometry), our equation simplifies to:  sin((π / 2) - x) = 1 * cos x - 0 * sin x, which further simplifies to sin((π / 2) - x) = cos x.

The x and y coordinates on the circle will be such that they satisfy the equation of the unit circle.

If a circle O has radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane, then, its equation is given as:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

A unit circle refers to a circle with unit radius (r = 1 unit) and positioned at center ( coordinates of origin = (h,k) = (0,0))

Thus, the equation of unit circle would be:

[tex]x^2 + y^2 =1[/tex]

Getting expression for y in terms of x,

[tex]x^2 + y^2 =1\\\\y = \pm \sqrt{1 - x^2}[/tex]

Using this equation to evaluate x for all given y:

[tex]\pm \dfrac{\sqrt{5}}{3} = \pm \sqrt{1-x^2}\\\\\text{Squaring both the sides}\\\\\dfrac{5}{9} = 1 - x^2\\\\x^2 = \dfrac{4}{9}\\\\x = \pm \dfrac{2}{3}[/tex]

From the options available, the fourth block seems valid.

Thus, we get:

[tex]y = \pm \dfrac{\sqrt{5}}{{3}} \rightarrow \left(\dfrac{2}{3}, y\right)[/tex]

[tex]\pm \dfrac{\sqrt{7}}{3} = \pm \sqrt{1-x^2}\\\\\text{Squaring both the sides}\\\\\dfrac{7}{9} = 1 - x^2\\\\x^2 = \dfrac{2}{9}\\\\x = \pm \dfrac{\sqrt{2}}{3}[/tex]

From the options available, the fourth block seems valid.

Thus, we get: [tex]y = \pm \dfrac{\sqrt{7}}{{3}} \rightarrow \left(\dfrac{\sqrt{2}}{3}, y\right)[/tex]

[tex]\pm \dfrac{3}{5} = \pm \sqrt{1-x^2}\\\\\text{Squaring both the sides}\\\\\dfrac{9}{25} = 1 - x^2\\\\x^2 = \dfrac{16}{25}\\\\x = \pm \dfrac{4}{5}[/tex]

From the options available, the fourth block seems valid.

Thus, we get: [tex]y = \pm \dfrac{3}{5} \rightarrow \left(\dfrac{4}{5}, y\right)[/tex]

[tex]\pm \dfrac{2\sqrt{2}}{3} = \pm \sqrt{1-x^2}\\\\\text{Squaring both the sides}\\\\\dfrac{8}{9} = 1 - x^2\\\\x^2 = \dfrac{1}{9}\\\\x = \pm \dfrac{1}{3}[/tex]

From the options available, the fourth block seems valid.

Thus, we get: [tex]y = \pm \dfrac{2\sqrt{2}}{{3}} \rightarrow \left(\dfrac{1}{3}, y\right)[/tex]
