Answer:
∠ 4 = 130°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 is an exterior angle of the triangle , so
∠ 4 = ∠ 1 + ∠ 2 ( substitute values )
11x + 9 = 6x + 6 + 4x + 14 , that is
11x + 9 = 10x + 20 ( subtract 10x from both sides )
x + 9 = 20 ( subtract 9 from both sides )
x = 11
Then
∠ 4 = 11x + 9 = 11(11) + 9 = 121 + 9 = 130°
your friend may have only calculated ∠ 1
∠ 1 = 6x + 6 = 6(11) + 6 = 66 + 6 = 72°

Use the relationship between the angles in the figure to answer the question. Which equation can be used to find the value of x?.
Answers
The sum of all the angles made by a straight line is 180°. Then the value of x is 61°.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
The angles are shown on the diagram.
The angles are 52° and 67°. And let the other angle be x.
We know that the sum of all the angles made by a straight line is 180°.
Then we have
x + 52° + 67° = 180°
On simplifying, we have the value of x.
x = 61°
Thus, the value of x is 61°.

Assuming that Sandra makes no purchases and no payments with either card, after four years, which card’s balance will have increased by more, and how much greater will that increase be? a. Card Q’s balance increased by $7. 22 more than Card P’s balance. B. Card Q’s balance increased by $6. 69 more than Card P’s balance. C. Card P’s balance increased by $3. 43 more than Card Q’s balance. D. Card P’s balance increased by $0. 80 more than Card Q’s balance.
Answers
The total amount is equal to the sum of principal and interest. Option C is correct. The amount on Card P increased by $3.43 more than the sum on Card Q.
What is a credit card?
A credit card is a payment card offered to users to enable the cardholder to pay a merchant for goods and services based on the cardholder's incurred debt.
The given data in the problem is;
Time period = 4 years
Increase rate for card p= 10. 19%,
principal for card P= $726. 19
principal for card Q = $855. 20
Increase rate for card Q= 8. 63%
The value obtained after the interest is commutative balance.
total cumulative balance in Card P = $1080.70
total cumulative balance in Card Q= $1,206.28.
Card P has a total cumulative balance of $1080.70 during the last four years, whereas Card Q has a total accumulated balance of $1,206.28.
When the principal is removed from the cumulative value, Card P would have earned more interest than Card Q based on the principal outlay.
Intreast for card P = $1080.70- $726.19 = $354.51
Intreast for card Q= $1206-$854.92=$351.08
The interest over the four years would be $354.51 and $351.08, respectively,
Hence option C is correct. Card P’s balance increased by $3. 43 more than Card Q’s balance.

Answer:
p = 35
Step-by-step explanation:
( 2p + 5 ) + ( 3p ) = 180
-
2p+5+3p=180
Combine 2p and 3p to get 5p.
-
5p+5=180
Subtract 5 from both sides.
-
5p=180−5
Subtract 5 from 180 to get 175.

5p=175
Divide both sides by 5.
p = 175\5
Divide 175 by 5 to get 35.

Answers
The bond package that will cost Sylvia less will be C. broker U's package costs $156.02 less money than broker V's package.
How to calculate the bond packageBroker U: 2.8% commission
2 par value bonds $1,000 x 96.674% = $1,933.48
3 par value bond $500 x 109.330% = $1,639.95
2 par value bonds $1,000 x 103.851% = $2,077.02
Silvia's total investment:
= ($1,933.48 + $1,639.95 + $2,077.02) x 1.028
= $5,808.66
Broker V: $65 per bond plus
4 par value bonds $500 x 105.142% = $2,102.84
1 par value bond $500 x 85.990% = $429.95
3 par value bonds $1,000 x 97.063% = $2,911.89
Silvia's total investment will be:
= $2,102.84 + $429.95 + $2,911.89 + (8 x $65)
= $5,964.68
Broker V's offer - broker U's offer:
= $5,964.68 - $5,808.66

A grocer mixes trail mix that costs $3. 00 per pound with trail mix that costs $1. 50 per
pound. He makes 15 lb of trail mix that costs $2. 50 per pound. How much of each
trail mix did the
grocer
use?
Answers
Answer:
15
Step-by-step explanation:
2 + 13 = 15
15( 3 ) = 45
45-35= 15
The grocer used 10 lbs of $3.00 per pound trail mix and 5 lbs of $1.50 per pound trail mix.
What is Algebra?Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations.
As per the given data:
Cost of one trail mix = $3.00 per pound
Cost of another trail mix = $1. 50 per pound
The grocer makes 15 lb of trail mix that costs $2.50 per pound.
Let's assume the grocer used 'A' pounds of $3.00 per pound trail mix and 'B' pounds of $1. 50 per pound trail mix.
Total quantity of $2.50 per pound trail mix = 15 lb
Now, from the given data,
A + B = 15 ...(i)
Also, the total cost is going to remain the same.
3A + 1.5B = 15 × 2.50
3A + 1.5B = 37.5 ...(ii)
Using eq(i) A = 15 - B
Substituting in (ii):
3(15 - B) + 1.5B = 37.5
45 - 3B + 1.5B = 37.5
B = 7.5/1.5
B = 5
and A = 10
The grocer used 10 lbs of $3.00 per pound trail mix and 5 lbs of $1.50 per pound trail mix.
Hence, The grocer used 10 lbs of $3.00 per pound trail mix and 5 lbs of $1.50 per pound trail mix.

Circle B has a center at point (0, 2) and a point W on the circle at (3, 3). Which equation represents a line that is tangent to the circle and goes through the point W?
Answers
According to the given information, the equation represents a line that is tangent to the circle and goes through the point W is given by:
y = -x + 6.
What is the equation of the circle?The equation of a circle of center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In this problem, we have that the center is at point (0,2), hence:
[tex]x^2 + (y - 2)^2 = r^2[/tex]
It goes through point (3,3), hence:
[tex]3^2 + (3 - 2)^2 = r^2[/tex]
[tex]r^2 = 10[/tex]
Hence, the equation is:
[tex]x^2 + (y - 2)^2 = 10[/tex]
What is the equation of the tangent line at point W?It is given by:
[tex]y - y(0) = \frac{dy}{dx}|_{W}(x - x(0))[/tex]
Applying implicit differentiation, we have that:
[tex]2x + 2y\frac{dy}{dy} = 0[/tex]
[tex]\frac{dy}{dx} = -\frac{x}{y}[/tex]
Point W(3,3), hence:
[tex](x_0, y_0) = (3,3)[/tex]
[tex]\frac{dy}{dx} = -\frac{3}{3} = -1[/tex]
Hence the equation is:
y - 3 = -(x - 3).
y = -x + 6.

Red bell pepper = $2.90
Green bell pepper = $1.90
The price per pound for both type of pepper is given as:
Rate = $1.60 per pound
So, the total pound is calculated as:
Pound = Total amount / Rate
This gives
[tex]Pound = \frac{2.90 + 1.90}{1.60}[/tex]
