Step-by-step explanation:
Total sum of angles in a triangle is 180
I'll do the first one, you can try the second
9x + 5 + 78 + 25 = 180
9x + 108 = 180
9x = 72
x = 8

a) 16.4 m, 101°b) 6.22 m, 51 m²Step-by-step explanation:
Find the measure of angle Q:
50° + (180° - 130°) = 100°a) Find PR using the law of cosines:
PR = √(8² + 13² - 28*13*cos 100°) = 16.4 m (rounded)Find ∠P using law of sines:
16.4/sin 100° = 13/ sin Pm∠P = arcsin (13 sin 100° / 16.4) = 51° (rounded)The bearing of R from P is:
50° + 51° = 101°b)
Find the measure of h, the distance from Q to PR:
h/ PQ = sin Ph = PQ sin Ph = 8 sin 51° = 6.22 mFind the area of ΔPQR:

The axis of symmetry for the graph of the function f(x) = 3x^2 + bx + 4 is x = 3/2 . What is the value of b?
Answers
Answer:
b = -9
Step-by-step explanation:
Axis of symmetry of a parabola = -b / 2a.
Where y = ax² + bx + c.
Given f(x) = 3x^2 + bx + 4,
a = 3, and c = 4.
If the axis of symmetry is 3/2, than b can be found by substitution and algebra.
[ x = -b / 2a ] → [ 3 / 2 = -b / 2a ] →
[ 3 / 2 = -b / 2 (3) ] → [ 3 / 2 = -b / 6 ] →
[ 3 / 2 × 6 = -b / 6 × 6 ] → [ 18 / 2 = -b ] →
[ 9 = -b ] → [ -b = 9 ] → [ (-)(-b) = (-)(9) ] →
b = -9

Answer: positive, linear association
Step-by-step explanation: that is the answer, because the dots are rising up in a slope
Answer:
The answer is simple: Positive, linear association. Why is that? It is moving from left to right, increasing as it goes. That is a sign of a positive slope. And, this has a linear association because the points are jumbled together in a clear direction, so we know that we can place a line of best fit.

Answers
Answer:
The properties of trapezoid apply by definition (parallel bases).
The legs are congruent by definition.
The lower base angles are congruent.
The upper base angles are congruent.
Any lower base angle is supplementary to any upper base angle.
The diagonals are congruent.The bases are parallel by definition.
Each lower base angle is supplementary to the upper base angle on the same side.

Is 9/10, 1 1/5, 1 1/2 a right triangle?
Answers
Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle

1. Get a blank paper or sugar board or cardboard/ calendar to complete the given task.
2. Use your pencil and compass to scribe or draw three different size circles on the blank paper/ calendar/ cardboard/sugar board
3. At the back of each circle label them 1,2 and 3 respectively.
4. Next use your ruler to measure the radius of the circle which is from the center to the circumference of the circle.
Ensure to record your measurement.
5. Use your ruler and measure the diameter goes straight across the circle, through the center (radius).
Ensure to record the measurements for each circle.
6. Then you will repeat steps 4 and 5, while using a string along with your ruler to measurement the circumference for each of the circle. Ensure to record your measurements
7. After completing your measurement write a conclusion for what you observed about the measurements for the diameter, radius and circumference for the three circles.

Because they are proportional, the two points have to be equal if they were like a fraction. This means (15,3) would be 15/3 which is equal to 5. The other point is (5,?), so that means that the point will have to be 1. This is because then the point will be equal to 5.

A cattle rancher needs to construct a new silo in which to store cattle feed. The silo will cost $2000. The rancher pays 15% as a down payment and finances the balance for 60 months at an APR of 7.50% . Determine the rancher's total finance charge and monthly payment.
a) Total finance charge = $368.22; Monthly payment =$34.47
Answers
Answer:
Monthly payment = $34.06
Finance charge = $343.87
Step-by-step explanation:
Given that:
Cost of silo = $2000
Down payment = 15% = (0.15) * 2000 = $300
Loan amount = $2000 - $300 = $1700
Period = 60 months = 5 years
APR = 7.5%
Using then monthly payment calculator, with the satiated parameters inputted :
The monthly payment is $34.06
The total amount paid over 60 months = $2,043.87
Therefore, finance charge = (total amount paid - loan amount)
$2043.87 - $1700
= $343.87
