How much of an alloy that is 10 percent copper should be mixed with 500 ounces of an alloy that is 90?

1 answer:

6 0

So 500ounces is 90% of the alloy.
So 500:90
Now divide both sides by 9.
500/9:10
So thats
55.56:10 or
55 5/9:10
Or keep it as
500/9:10

What is 0.25% of K2 000?

goldfiish [28.3K]

$\huge\text{Hey there!}$

$\large\text{When you hear/see the word of in mathematics, it usually means }\\\large\text{\bf multiplication. }$

$\large\text{So, when you think of think of the word \underline{of} think of its asking you to}\\\large\text{\bf multiply }$

$\large\text{Now that we got that run down out of the way lets answer your given}\\\large\text{question}$

$\large\textsf{0.25\% of 2,000}$

$\large\textsf{= 0.25\%} \times \large\textsf{2,000}$

$\large\textsf{0.25\%} = \mathsf{\bf \dfrac{25}{100}}$

$\mathsf{= \dfrac{25}{100} \times 2,000}$

$\mathsf{\dfrac{25}{100}= \bf 0.0025}$

$\large\textsf{= 0.0025} \times \large\textsf{2,000}$

$\large\text{= \bf 5}$

$\boxed{\boxed{\huge\text{Therefore, your ANSWER is: \textsf 5}}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$

PLEASE HELP ASAP THE DETAILS ARE BELOW.What is the value of x?

Aloiza [94]

Answer:

x = 30°.

Step-by-step explanation:

The dashes on the three lines indicate that the three lines are of equal lengths. The smaller triangle made out of the three lines (the one with two vertices on the circumference of the circle and one at the center of the circle) is an isosceles triangle. All three of the triangle's interior angles are 60° since it is isosceles.

The line (the one with arrows on its ends) touches the circle at only one point. That line is a tangent to the circle. That line is perpendicular to the segment that connects the center of the circle to the point of tangency. The angle between the two will be 90°.

The largest triangle includes three angles:

The angle with the center of the circle as its vertice: 60°;
The right angle due to the tangent to the circle: 90°;
The angle x°.

What is the value of x?

The three interior angles of a triangle add up to 180°. As a result,

60° + 90° + x° = 180°

x = 180 - 90 - 60 = 30.
