Answer:

The price was $391.30.

Step-by-step explanation:

We can answer this using algebra:-

Let the original price be $x, then:

x + 15% of x = 450

x + 0.15x = 450

1.15x = 450

x = 450/1.15

x = 391.304

Answer:5

Step-by-step explanation:

Answer: 63 children and 88 adults swam at the public pool that​ day.

Step-by-step explanation:

Let x = Number of children

y= Number of adults

As per given , we have

x+y=151            (i)

1.50x+2y=270.50          (ii)

Multiply 2 on both sides of (i)

2x+2y = 302          (iii)

Eliminate (ii) from (iii)

0.5x=31.5

⇒ x = 63   [Divide both sides by 0.5]

Put value of x in (i) , we get

63+y= 151

⇒ y= 151-63 =88

Hence, 63 children and 88 adults swam at the public pool that​ day.

C. tan(30°)

Step-by-step explanation:

edge yuh yuhhhhh

The equivalent fraction is [tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex].

The given expression is tan 40°-tan 10°/1+tan 40°.tan 10°.

When simplifying trigonometric expressions, one approach is to change everything into sine or cosine.

Now, [tex]\frac{\frac{sin40\textdegree}{cos40\textdegree} -\frac{sin10\textdegree}{cos10\textdegree}}{1+\frac{sin40\textdegree}{cos40\textdegree} .\frac{sin10\textdegree}{cos10\textdegree} }[/tex]

=[tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex]

Therefore, the equivalent fraction is [tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex].

Answer:

2.5

Step-by-step explanation:

she has buys 3 shirts for 8.50 which = 25.5

then she buys 2 pair of pants for $22 because 2 x 11=22

so then 22 + 25.5 = 47.50

50.00- 47.50= 2.50

Answer:

AB = 15

m∠A = 53.1°

m∠B = 36.9°

Step-by-step explanation:

From the picture attached,

By Applying Pythagoras theorem,

AB² = AC² + BC²

AB² = 9² + (12)²

AB² = 81 + 144

AB = √225

AB = 15

tan(B) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

          = [tex]\frac{12}{9}[/tex]

          = 1.3333

B = [tex]\text{tan}^{-1}(1.3333)[/tex]

   = 53.13

   ≈ 53.1°

Since, m∠A + m∠B + m∠C = 180°

m∠A + 53.1° + 90° = 180°

m∠A = 180°- 143.1°

        = 36.9°

Answer:

AB = 15

m∠A = 53.1°

m∠B = 36.9°

Complete Question

The area A (in square feet) of the rectangular shed is given by 6x³+7x²+11x+21.And one side of the rectangular is 2x+3. Use polynomial long division to find an expression for the length (in feet) of the shed.

Answer:

3x² - x +7

Step-by-step explanation:

Using the long division method:

We have :

Divisor : 6x³+7x²+11x+21

Dividend : 2x+3

Quotient : the length (in feet) of the shed = ???

Hence, we solve below

6x³+7x²+11x+21 ÷ 2x + 3

3x² -x + 7

______________________

2x+3 l 6x³+7x²+11x+21

The sum of the first 8 terms will be:

Step-by-step explanation:

Given the sequence

[tex]36, 30, 25, ...[/tex]

A geometric sequence has a constant ratio and is defined by

[tex]a_n=a_0\cdot r^{n-1}[/tex]

computing the common ratio

[tex]\frac{30}{36}=\frac{5}{6},\:\quad \frac{25}{30}=\frac{5}{6}[/tex]

[tex]r=\frac{5}{6}[/tex]

As the first element is

[tex]a_1=36[/tex]

so the nth term will be:

[tex]a_n=a_0\cdot r^{n-1}[/tex]

[tex]a_n=36\left(\frac{5}{6}\right)^{n-1}[/tex]

Geometric sequence sum formula

[tex]a_1\frac{1-r^n}{1-r}[/tex]

Plugin the values to determine the sum of the first 8 terms

[tex]n=8,\:\spacea_1=36,\:\spacer=\frac{5}{6}[/tex]

[tex]=36\cdot \frac{1-\left(\frac{5}{6}\right)^8}{1-\frac{5}{6}}[/tex]

[tex]=\frac{\left(1-\left(\frac{5}{6}\right)^8\right)\cdot \:36}{1-\frac{5}{6}}[/tex]    

[tex]=\frac{36\left(-\left(\frac{5}{6}\right)^8+1\right)}{\frac{1}{6}}[/tex]

[tex]=\frac{36\left(-\frac{390625}{1679616}+1\right)}{\frac{1}{6}}[/tex]

[tex]=\frac{\left(1-\frac{390625}{1679616}\right)\cdot \:36\cdot \:6}{1}[/tex]

[tex]=\frac{216\left(-\frac{390625}{1679616}+1\right)}{1}[/tex]

[tex]=\frac{216\cdot \frac{1288991}{1679616}}{1}[/tex]

[tex]=216\cdot \frac{1288991}{1679616}[/tex]

[tex]=\frac{1288991\cdot \:216}{1679616}[/tex]

[tex]=\frac{278422056}{1679616}[/tex]

[tex]=\frac{1288991}{7776}[/tex]

 Therefore, the sum of the first 8 terms will be:
