Answer:
10.4
Step-by-step explanation:
Let the number be x
Sum of x and -3.2 : x + (-3.2) = x - 3.2
1/4 times the sum of a number and −3.2 = (1/4) * (x - 3.2)
[tex]\dfrac{1}{4}* \left( x - 3.2 \right) = 1.8\\\\\Multiply \ the \ whole \ equation \ by \ 4 \\\\4*\dfrac{1}{4} *(x - 3.2) = 1.8*4\\\\\\x - 3.2 = 7.2\\\\Add \ 3.2 \ to \ both \ sides\\\\\\x = 7.2 + 3.2\\[/tex]
x = 10.4

0.001 meter per kilometer
Pls
Answer: It would be the first one, 0.001 kilometers per meter.
Step-by-step explanation: is 1,000 meters is equal to 1 kilometer, you would have to move the decimal on each until one is at one and the other is at 0.001. This would leave you with the first answer. Hope this helps!

Someone please help! Will mark brainliest!!! 2.200/54°20
Answer:
Step-by-step explanation:
Hmmmm... Several big questions about this simple phrase.
1) Are you using the European convention of using a period as an American would use a comma? Does 2.200 mean 2200 or 2.2 with precision to the nearest thousandths.
I will ASSUME you are using the European form and 2.200 = 2200
2) PEMDAS says multiply and divide are equal weight so complete as read left to right.
2200/54 = 40.740740740...
40.740740740...•20 = 814.814814814814...
or, if this is really supposed to be
2.200 / (54(20)) then = 2.037037037037...
Then again, the symbol between the 4 and last 2 is not really a multiplication symbol. It's more of a circle. Now does that mean degrees? and if degrees, are they temperature or angular? Or does that circle indicate an exponent of zero, in which case 54° = 1 and PEMDAS would say the result is 0.110 to an American and 110 to a European.
What we have here is a failure to communicate.

Find the angle between u and v, rounded to the nearest tenth degree.
u = (4, 0, 2), v = (6, −3, 0)
Answer:
The angle between vectors u and v is [tex]\theta\approx36.9^\circ[/tex]
Step-by-step explanation:
Recall:
Angle between vectors u and v --> [tex]\theta=cos^{-1}(\frac{u\bullet v}{||u||*||v||})[/tex]Dot product (three-dimensional) --> [tex]u\bullet v=u_1v_1+u_2v_2+u_3v_3[/tex]Magnitude (three-dimensional, vector u) --> [tex]||u||=\sqrt{u_1^2+u_2^2+u_3^2}[/tex]Magnitude (three-dimensional, vector v) --> [tex]||v||=\sqrt{v_1^2+v_2^2+v_3^2}[/tex]Calculation:
Dot product --> [tex]u\bullet v=(4)(6)+(0)(-3)+(2)(0)=24[/tex]Magnitude (u) --> [tex]||u||=\sqrt{4^2+0^2+2^2}=\sqrt{16+0+4}=\sqrt{20}=2\sqrt{5}[/tex]Magnitude (v) --> [tex]||v||=\sqrt{6^2+(-3)^2+0^2}=\sqrt{36+9+0}=\sqrt{45}=3\sqrt{5}[/tex]Plug dot product and magnitudes into formula:
[tex]\theta=cos^{-1}(\frac{u\bullet v}{||u||*||v||})=cos^{-1}(\frac{24}{2\sqrt{5}*3\sqrt{5}})=cos^{-1}(\frac{24}{6*5})=cos^{-1}(\frac{24}{30})\approx36.9^{\circ}[/tex]
Conclusion:
The angle between vectors u and v is [tex]\theta\approx36.9^\circ[/tex]

What is the length of the hypotenuse?
Answer:
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

How can you multiply fractions and mixed numbers?
Step-by-step explanation:
In order to multiply fractions and mixed numbers, you must first transform the mixed number into a single fraction (will most likely turn into an improper fraction). An improper fraction is a fraction where the numerator is greater than the denominator.
Example:Suppose that you were given the following fractions to multiply:
[tex]\large\mathsf{\frac{5}{7}\:\times\:2\frac{3}{5}}[/tex]
The first step is to transform the mixed fraction, [tex]\large\mathsf{2\:\frac{3}{5}}[/tex], into a single fraction.
You will have to multiply the denominator with the whole number, then add the numerator. The denominator does not change when you do this transformation processs.
The mixed fraction will now turn into the following improper fraction:
[tex]\large\mathsf{2\:\frac{3}{5}}[/tex] ⇒ [tex]\large\mathsf{\frac{13}{5}}[/tex]
Now, you will be able to multiply [tex]\large\mathsf{\frac{5}{7}}[/tex] and [tex]\large\mathsf{\frac{13}{5}}[/tex] together by multiplying the numerator, 5 and 13 and the denominator, 7 and 5.
[tex]\large\mathsf{\frac{5}{7}\:\times\:\frac{13}{5}\:=\:\frac{5\:\times\:13}{7\:\times\:5}\:=\:\frac{65}{35}}[/tex]
Since the product of the two fractions is an improper fraction, it is often customary to express the fraction into its lowest terms. Given the improper fraction, [tex]\large\mathsf{\frac{65}{35}}[/tex], the greatest common factor between 65 and 35 is 5.
Hence, we could simply divide the numerator and the denominator by [tex]\large\mathsf{\frac{5}{5}}[/tex] to simplify the fraction.
[tex]\large\mathsf{\frac{65}{35}\:\div\:\frac{5}{5}\:=\:\frac{13}{7}}[/tex]
Therefore, the final answer is: [tex]\large\mathsf{\frac{13}{7}}[/tex] . To transform this improper fraction into a mixed number, simply divide its numerator by the denominator, thereby resulting into the following mixed number: [tex]\large\mathsf{1\:\frac{6}{7}}[/tex].

8 8/7 + (7 5/6 - 2 1/3)
Enter your answer as a mixed number in simplest form by filling in the boxes.
(Giving away brainliest, 5 stars and a thanks for whoever answers first with the correct answer)
Evaluate:- 8 8/7 + (7 5/6 - 2 1/3)
⟼ (63+7)/7 + [(42+5)/6 - (6+1)/3
⟼70/7 + [47/7 - 7/3]
⟼ 70/7 + [(141- 49)/21]
⟼ 70/7 + [92/21]
⟼ 70/7 + 92/21
Now, take the LCM of 7 and 21 is 21.
so,
⟼ (210 + 92)/21
⟼ 302/21 or 14(8/21) Ans.

Which of the following is a solution of 4 Vx-3 = 16?
Answer:
19/4
Step-by-step explanation:
4x - 3 = 16
4x - 3 + 3 = 16 + 3
Simplify:
4x - 3 + 3 = 16 + 3
4X = 16 + 3
4x = 16 + 3
4X = 19
Then divide:
4x = 19
4X/4 = 19/4
Simplify:
x = 19/4.
