Help. Examine the figure below. Determine which of the following angle measures are correct PICK up 2 answers
Answers
Answer:
RPQ = 30 and QRP = 75
Step-by-step explanation:
First we need to find "x".
Since we know that all the angles of a triangle must equal 180 and we know that angles PQR and QRP are the same (Due to the fact that two of the lengths of the triangle are the same) we can set up an equation.
x + (2x + 15) + (2x + 15) = 180
1. we can drop the parentheses (when there is a + in front of an expression in parentheses, the expression remains the same)
x + 2x + 15 + 2x + 15 = 180
2. We can collect the like terms to simplify the equation. (x and 2x and 2x combine to equal 5x) (Remember that there is a hidden 1 behind an "x" without a number next to it)
(the two 15's add together to make 30)
This leaves us with this equation
5x + 30 = 180
3. Now we suptract the constant from 180 (The constant is 30)
5x = 180 - 30
5x = 150
4. Now we devide both sides by 5
x = 30
Next we can find all of the angles
PRQ = (2x + 15)
1. PRQ = (2(30) + 15)
2. PRQ = (60 + 15)
3. PRQ = 75
RQP = (2x + 15)
1. RQP = (2(30) + 15)
2. RQP = (60 + 15)
3. RQP = 75
RPQ = x
RPQ = 30

The length of base of the triangle is given by BC = 7 feet
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle BC = a
Let the hypotenuse of the triangle be c = 25 feet
Let the height of the triangle be b = 24 feet
And , For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
So , the base BC = √ ( 25 )² - ( 24 )²
The base of the triangle BC = √ ( 625 - 576 )
The base of the triangle BC = √ ( 49 )
The base of the triangle BC = 7 feet
Hence , the length of base of triangle is 7 feet

Ducklings cost $15 each. Chicks cost $12 each. You have $60 to spend on poultry
Answers
Answer:
If your question is how much money you have after you purchase a duckling and a chick, your answer would be $33. It seems to me like you posted the question without finishing it. I'm guessing you were about to mention how many ducklings and chicks you were going to buy and how much money you would have leftover for the poultry.
Step-by-step explanation:
To solve your problem you must add what you're buying and then subtract from your original amount.
For example: if you want one duckling and one chick and you would like to know how much money you have leftover to buy poultry. $15 + $12= $27 dollars in all. Then, you will subtract $27 dollars from $60, this way you know how much money you will have left in order to buy the poultry. $60 - $27= $33.

Answer: a = -3
Step-by-step explanation:
first, we remove the parentheses.
4 - 9/5a - 12/5 = 7
then, we calculate.
8/5 - 9/5a = 7
next, we multiply both sides.
8 - 9a = 35
then, we move the constant to the right.
-9a = 35 - 8
next, we calculate.
-9a = 27
finally, we divide both sides.
a = -3

A peach pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice of pie that contained exactly 5 peaches, what wqs the angle measure of the slice to the nearest tenth of a degree?
Answers
Answer:
138.5°
Step-by-step explanation:
A peach pie is in the form of a circle. The sum of angles in a pie is equal to 360°.
Since there are 13 peaches evenly distributed, therefore each peach occupies 360/13 degrees.
Joe ate one slice of pie that contained exactly 5 peaches, hence:
Angle measure of slice = (number of peaches in the slice / total number of peaches) * 360°
Angle measure of slice = (5 / 13) * 360°
Angle measure of slice = 138.5°

Answers
Answer:
$5.77
Step-by-step explanation:
Given expression:
1.8s + 0.65b
where,
s = the number of pounds of strawberries
b = the number of pounds bananas
If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas
s = 2.7 pounds
b = 1.4 pounds
how much did he spend?
1.8s + 0.65b
= 1.8(2.7) + 0.65(1.4)
= 4.86 + 0.91
= $5.77
He spent $5.77 on both items
Which function is best represented by the graph?
Answers
Answer:
J
Step-by-step explanation:
First look at the y-intercept. When y=0, you get 8 on the graph, so in the equation it has to give you 8 as well.
This narrows it down to F G J
Next, the slope of the graph is negative because its tilting downwards.
This narrows it down to G J
Finally, on the graph when y=0, you get 6, so the equation has to meet this too
With your choices narrowed down to G and J, calculate the x-intercepts.
0= -4/3x+8
-8= -4/3x
-8(-3/4)=x
x=6
Answer:
The answer is J
Step-by-step explanation:
the y-intercept is 8 and to find the slope you count rise over run, well the graph is too small to tell what points are actually on the lines, but it's given that (0,8) and (6,0) are points. making the rise/run= to 8/6 and then simplify to 4/3. and you can tell that the slope is negative because it's going downward from left to right.
