Mandy works construction. She knows that a 555 meter long metal bar has a mass of 40 \text{ kg}40 kg40, start text, space, k, g, end text. Mandy wants to figure out the mass (w)(w)left parenthesis, w, right parenthesis of a bar made out of the same metal that is 333 meters long and the same thickness. What is the mass of the shorter bar?
Answer:
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

If chocolate chips have 20 calories in 2t how many calories in 3 cups
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

What is 232 divided by 4
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.

Back to my question. I have this problem that I cant solve.
-21-9k=-8(6k+3)
I need to get the answer k= -0.08
Can someone please help me and give me the explanation?
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
Here's the answer: -1/13 or -0.08.

An airplane is flying at a speed of 350 mph at an angle of 100 degrees. A wind is blowing at 50 mph at an angle of 40 degrees. Find the resulting speed and direction.
The resulting speed and direction of the airplane are approximately 377.492 miles per hour and 93.413°, respectively.
How to apply vectors to find absolute velocity of the airplane
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]

⇒ (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;

Given: Segment AD is an altitude
Find: BC
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
