Answer:

[tex]BC=71\text{ units}[/tex]

Step-by-step explanation:

Since AD is an altitude, we know that AD⊥BC by the definition of altitudes.

Then, this means that ∠ADC will be 90° by the definition of perpendicular lines. Therefore:

[tex]12x+6=90[/tex]

Solve for x. Subtract 6 from both sides and then divide by 12:

[tex]12x=84\\[/tex]

[tex]x=7[/tex]

Therefore, the value of x is 7.

BC is the addition of the segments BD and DC. In other words:

[tex]BC=BD+DC[/tex]

We already know the equations of BD and DC. Substitute:

[tex]BC=(5x-7)+(2x+29)[/tex]

Since we know that the value of x is 7, substitute 7 for x and evaluate for BC:

[tex]BC=(5(7)-7)+(2(7)+29))[/tex]

Evaluate:

[tex]BC=(35-7)+(14+29)[/tex]

Evaluate:

[tex]BC=28+43=71[/tex]

Therefore, the value of BC is 71 units.

Answer:

BC = 71

Step-by-step explanation:

12x + 6 = 90

x = 7

5x - 7 + 2x + 29 = 7x + 22

7(7) + 22 = 49 + 22

49 + 22 = 71

BC = 71

Answer:

Please Specify if the chocolate chips are measured in teaspoon or tablespoon?

Step-by-step explanation:

Assuming that the chocolate chips are measured in Teaspoons

given: 20 calories= 2 teaspoons

Now we can say that 48 teaspoons= 1 cup

therefore if 2 teaspoons make 20 calories , how many does 48 teaspoons make?

(48x20)/2 = 480 calories

we can now say that 48 teaspoons =1 cup = 480 calories

3x480=1440

so, 3 cups= 1440 calories

Answer: 58

Step-by-step explanation:

1st step: Start by setting it up with the divisor 4 on the left side and the dividend 232

2nd step: The divisor (4) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

3rd step: Multiply the divisor by the result in the previous step (4 x 0 = 0) and write that answer below the dividend.

4th step: Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.Move down the 2nd digit of the dividend (3)

5th step: The divisor (4) goes into the bottom number (23), 5 time(s). Therefore, put 5 on top

6th step:  Multiply the divisor by the result in the previous step (4 x 5 = 20) and write that answer at the bottom. Subtract the result in the previous step from the number written above it. (23 - 20 = 3) and write the answer at the bottom.

7th step: Move down the last digit of the dividend (2). The divisor (4) goes into the bottom number (32), 8 time(s). Therefore put 8 on top

8th step:Multiply the divisor by the result in the previous step (4 x 8 = 32) and write the answer at the bottom. Then Subtract the result in the previous step from the number written above it. (32 - 32 = 0) and write the answer at the bottom.

Therefore, the answer to 232 divided by 4 is by using long division

The required quotient is 58.

Given that 232 ÷ 4.

The long division states that divident = divisor × quotient + remainder.

Let a and b be any real numbers. Consider a ÷ b gives a = b × q + r, that implies q is quotient and r is remainder such that 0 [tex]\leq[/tex] r [tex]\leq[/tex] b.

That implies,

[tex]\begin{array}{ccc}4)&232&(58\\_-&20\\&32&\\_-&32&\\&00&\end{array}[/tex]

Therefore, the required quotient is 58.

Answer:

1/4

unsimplified = 2/8

Step-by-step explanation:

2/8 is your answer because

you can see here that there are 8 bars that are being covered by his total sales. That means that 8 is the denominator, then, the money is going 2 more bars than 225 dollars. So if we see, then we can find out that the sales are going up till 275, and the difference of 275 and 225 is 50. And each bar over here represents a difference of 25. That means that 2/8 (1/4) of the sales are more than $225.

So hence, your answer is 1/4

Answer:

1/4

Step-by-step explanation:

From inspection of the box plot:

The left whisker (min value) to Q1 represents the bottom 25% of the data

Q1 to Q2 represents the second 25% of the data

Q2 to Q3 represents the third 25% of the data

Q3 to the right whisker (max value) represents the top 25%

Therefore, the sales of over $225 represent the top 25% of the data.  

25% represented as a fraction is 25/100 = 1/4

The vertex of the parabola will be;

⇒ (3, - 11)

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation is,

⇒ f (x)  = 2x² - 12x + 7

Now,

Since, The equation is,

⇒ f (x)  = 2x² - 12x + 7

It can be written as;

⇒ f (x)  = 2(x² - 6x) + 7

⇒ f (x)  = 2(x² - 6x + 9 - 9) + 7

⇒ f (x)  = 2(x² - 6x + 9) - 18 + 7

⇒ f (x)  = 2 (x - 3)² - 11

By comparing with standard form of parabola y = a (x - h)² + k, we get;

⇒ (h, k) = (3, - 11)

Thus, The vertex of the parabola will be;

⇒ (3, - 11)

Step-by-step explanation:

Simultaneous equations system

The resulting speed and direction of the airplane are approximately 377.492 miles per hour and 93.413°, respectively.

In this question we must apply vectors in rectangular form to determine the absolute velocity of an airplane. which is the sum of velocity at still air ([tex]\vec v_{A/W}[/tex]) and wind velocity ([tex]\vec v_{W}[/tex]), both in miles per hour. If we know that [tex]v_{W} = 50\,\frac{mi}{h}[/tex], [tex]\theta_{W} = 40^{\circ}[/tex], [tex]v_{A/W} = 350\,\frac{mi}{h}[/tex] and [tex]\theta_{A/W} = 100^{\circ}[/tex], then resulting velocity is:

[tex]\vec v_{A} = 50\cdot (\cos 40^{\circ}, \sin 40^{\circ}) + 350\cdot (\cos 100^{\circ}, \sin 100^{\circ})[/tex]

[tex]\vec v_{A} = (-22.474, 376.822)[/tex]

Whose magnitude ([tex]v_{A}[/tex]), in miles per hour, and direction ([tex]\theta[/tex]), in degrees, are, respectively:

[tex]v_{A} = \sqrt{(-22.474)^{2}+376.822^{2}}[/tex]

[tex]v_{A} \approx 377.492\,\frac{mi}{h}[/tex]

[tex]\theta_{A} = \tan^{-1} \left(\frac{376.822}{-22.474} \right)[/tex]

[tex]\theta_{A} \approx 93.413^{\circ}[/tex]

Here's how to solve your equation step by step:

−21−9k=−8(6k+3)

Step 1: Simplify both sides of the equation.

−21−9k=−8(6k+3)

−21+−9k=(−8)(6k)+(−8)(3) (Distribute)

−21+−9k=−48k+−24

−9k−21=−48k−24

Step 2: Add 48k to both sides.

−9k−21+48k=−48k−24+48k

39k−21=−24

Step 3: Add 21 to both sides.

39k−21+21=−24+21

39k=−3

Step 4: Divide both sides by 39.

39k/39 = -3/39

Answer:

Proportion b. 5/3 = 40/w is the answer and w = 24 kg.

Step-by-step explanation:

it is given in the question that a metal bar was 5 meter long and has a mass of 40 kg. Mandy makes a bar again by using same metal of length 3 meters and mass w.

Since metal of the rods are same so weight per meter of the rod will be same.

mass per meter of 5 meter rod = 40/5

mass per meter of 3 meter rod = w/3

Both are same so

40/5 = w/3 is the proportion Mandy will use.

By using this proportion Mandy will get w = 3×40/5 = 24 kg
