When Jennifer and Tom visit another country, they find two types of coins are used there, one with a Q on it and one with an E on it. Jennifer has 13 Q coins and Tom has 5 Q coins and 7 E coins. If Jennifer's coins have a total value of $0.65 and Tom's coins have a total value of $3.75, what is the value of each type of coin?
Answers
Answer:
q = $0.05
e = $0.5
Step-by-step explanation:
13q = 0.65 equation 1
5q + 7e = $3.75 equation 2
in equation 1, divide both sides of the equation by 13
q = 0.65 / 13 = 0.05
Substitute for the value of q in equation 2
5(0.05) + 7e = 3.75
0.25 + 7e = 3.75
collect like terms
3,75 - 0.25 = 7e
3.5 = 7e
e = 0.5

Find the value of x to the nearest tenth. In a triangle, one angle is 46 degree and second angle is 20 degree. The adjacent side of 46 degree angel is 7 and opposite side is x.
Answers
The value of x in the triangle is approximately 7.2 to the nearest tenth.
To determine the value of x in the triangle, we can use the trigonometric ratio of tangent (tan).
We are Given that one angle of the triangle is 46 degrees and the adjacent side to this angle is 7, we need to find the length of the opposite side (x).
The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side.
tan(46°) = x/7
Take the tangent of both sides of the equation:
tan(46°) = x/7
Multiply both sides by 7 to isolate x:
7 x tan(46°) = x
Use a calculator to find the tangent of 46 degrees:
tan(46°) ≈ 1.0355
Multiply 7 by the approximate value of the tangent:
7 x 1.0355 ≈ 7.249
Rounding the value of x to the nearest tenth, we find that x ≈ 7.2.
Therefore, to the nearest tenth, the value of x in the triangle is approximately 7.2.

The value of x to the nearest tenth is approximately 5.0.
To find the value of x, we can use the trigonometric relationship of the sine function in a right triangle. In this case, we have an angle of 46 degrees and the opposite side x.
The sine function is defined as the ratio of the length of the opposite side to the length of the hypotenuse. However, in this case, we don't know the length of the hypotenuse, but we can still find the value of x using the adjacent side.
Let's label the angle of 46 degrees as A, the adjacent side as B, and the opposite side as C.
sin(A) = C / B
sin(46°) = x / 7
To find the value of x, we can rearrange the equation:
x = 7 * sin(46°)
Using a calculator, we can evaluate sin(46°) and calculate the value of x:
x ≈ 7 * 0.7193
x ≈ 5.0351

13 5/8 Or 13.625
Explanation:
• Let’s start with 1/4. There are five days that has the amount of 1/4 of rainfall.
So we have to add all five of the 1/4 or just multiply:
1/4 x 5 = 5/4
• Now for the 3/8. There are twelve days that has that amount of rainfall.
3/8 x 12 = 36/8
• For 1/2. There are five days.
1/2 x 5 = 5/2
• For 5/8. There’s five days.
5/8 x 5 = 25/8
• Lastly for 3/4. There is three days.
3/4 x 3 = 9/4
• Now we add all of the amount together:
5/4 + 36/8 + 5/2 + 25/8 + 9/4
- To add, we have to find the Least Common Denominator (LCD), which is 8.
So we have to make all of the fractions into a denominator of 8 by multiplying:
5/4 —> 10/8 (Multiply by 2)
36/8 (Stays the same, already have the denominator of 8)
5/2 —> 20/8 (Multiply by 4)
25/8 (Stays the same, already have the denominator of 8)
9/4 —> 18/8 (Multiply by 2)
• Now add:
10/8 + 36/8 + 20/8 + 25/8 + 18/8 = 109/8
109/8 = 13 5/8
Or as decimal form: 13.625

PLEASE HELP!!! I have no clue how to find the perimeter of MNP
Answers
Answer:
130
Step-by-step explanation:
Triangle MNP is twice the size of triangle SRP. So 2(x+4)=5x-34.
Distribute: 2x+8=5x-34
Add 34 on both sides: 2x+42=5x
Subract 2x on both sides: 42=3x
Divide both sides by 3: 14=x
If x=14, then 5x-34
is 5(14)-34=70-34=36.
The perimeter of the triangle MNP is
MN+NP+PM.
MN is 36
NP is doubled the 22 because triangle MNP is twice the size of triangle MQS. So NP is 44.
PM is doubled the 25 because triangle MNP is twice the size of triangle QNR. So PM is 50.
The perimeter of the triangle MNP is
MN+NP+PM
=36+44+50
=130
