In the figure below, triangle QRS is isosceles, with QR SR.
If mSPQ = 36° and mQRS = 32°, what is mPQR?
A.
118°
B.
138°
C.
133°
D.
128°
Answers
Now divided 148/2 to get 74°.
In triangle SPQ, there is one right angle 90°, and mSPQ 36°
Add 90+36=126 and subtract that from 180 again
180-126=54°
Add 74° and 54° = 128°
The answer is D
Answer:
D
Step-by-step explanation:
since Δ QRS is isosceles then the base angles are congruent , that is
∠ RQS = ∠ RSQ = (180 - ∠ QRS ) ÷ 2 = (180 - 32)° ÷ 2 = 148° ÷ 2 = 74°
the sum of the 3 angles in Δ SPQ = 180° , then
∠ PQS = 180° - ∠ SPQ - ∠ PSQ = 180° - 36° - 90° = 54°
Then
∠ PQR = ∠ RQS + ∠ PQS = 74° + 54° = 128°

Help please V/5 = 3/7 v=
Answers
Answer:
v = 15/7, or 2.14
Step-by-step explanation:
Find a common denominator, or multiply both denominators by each other, and well as the numerator.
v/5 = 3/7 can be written as 7v/35 = 15/35
multiplying both sides with 35, we are left with 7v = 15
v = 15/7, or 2.14

If a towns population currently at 50,000 experiences 5% growth every 10 years, what will its population be in 25 years
Answers
Answer:
56503
Step-by-step explanation:
this grows exponentialy so at the start it would be 50,000 growing by 5% every ten years. but since there is only 2 ten years in 25 years we must cut the percent in half making 2.5%
Step 1
(50,000×5%)+50,000= 52500
Step 2
(52500×5%)+52500= 55125
step 3
(55125×2.5%) +55125= 56503

Leila will run less than 25 miles this week. So far, she has run 13 miles. What are the possible numbers of additional miles she will run?
Use t for the number of additional miles she will run.
Write your answer as aninequality solved for t.
Answers
Leila will run less than 25 miles this week. This means the inequality symbol will be this: "<". Since she has already ran 13 miles, we need to plug-in a variable for the additional miles she must run. The inequality should be like this when plugged-in: 25 < 13 + t.
The final answer to your question is 25 < 13 + t.

What is perimeter?The perimeter of an object is given by adding the side lengths of the object.
Given are two triangles, we need to find their perimeters and then the difference and the value of the perimeter when x = 3,
Blue:
P = 4x +2 +7x + 7+5x-4
= 16x +9-4 = 16x +5
Red:
P = x+3+2x - 5 + x + 7
= 4x + 10 - 5 = 4x + 5
Now,
The difference between the perimeter:
(16x + 5) - (4x + 5)
= 16x + 5 - 4x - 5
= 12x
The perimeter when x = 3
Blue: 16x + 5 ⇒ 16(3) + 5 = 48 + 5 = 53
Red: 4x + 5 ⇒ 4(3) + 5 = 12 + 5 = 17
Hence, the perimeters of the given triangle are 53 and 17 respectively.

The Happy Widget Company has a fixed cost of $1,378 each day to run their factory and a variable cost of $1.83 for each widget they produce.
Create a linear model for their daily cost.
How much does it cost them to produce 267 widgets?
Answers
The linear model for the daily cost is C(x) = $1378 + $1.83(x).
The cost of producing 267 widgets is $1,866.61
What is the cost of producing 267 widgets?
Fixed cost is the cost the remains constant with the number of widgets produced. Variable cost increases with the number of widgets produced. Daily cost is the sum of fixed cost and variable cost.
Fixed cost = fixed cost + (variable cost x number of widgets)
C(x) = $1378 + $1.83(x).
C(x) = $1378 + $1.83(267) = $1,866.61

Answers
Step-by-step explanation:
Make f(x) = 0
[tex] {x}^{2} + 6x + 11 = 0[/tex]
First, we move the constant term to the right hand side of the equality sign.[tex] {x}^{2} + 6x = - 11[/tex]
Then, we half the coefficient of x and square our result.[tex]( \frac{6}{2} ) ^{2} = 3 ^{2} = 9[/tex]
Now, we add the result to the both sides of the equation.[tex] {x}^{2} + 6x + 9 = - 11 + 9[/tex]
We can see that x²+6x+9 = (x+3)² {Try factorizing}Therefore,(x+3)²= -2
(x+3)²+2= 0
f(x)= (x+3)²+2
Which is the f(x) in graphing form.

A(shaded) =47cm^2
Step-by-step explanation:
To find the area of the shaded part we write:
A(shaded) = A(triangle)-A(rectangle)
Let's find A(rectangle):
The formula of the area of a rectangle is given by:
A(rectangle)=L*W
Where L is the length of the rectangle and W is the width of the rectangle.
Given in the figure:
L=4cm
W=2cm
We get:
A(rectangle) = 4*2 = 8cm^2
Now, let's find A(triangle):
The formula of the area of a triangle is given by:
A(triangle) = (b*h) /2
Where b is the base of the triangle and h is the height of the triangle
Given in the figure:
b= 11cm
h= 3+4+3 = 10cm
We get:
A(triangle) = (11*10)/2 = 55cm^2
Now that we found the areas of both, the rectangle and the triangle, we can go back to the following formula to find the area of the shaded part:
A(shaded) = A(triangle)-A(rectangle)
A(shaded)= 55 - 8= 47cm^2
Area of triangle = 1/2 x 11 x (3+4+3) = 55 cm²
Area of rectangle = 4 x 2 = 8 cm²
Area of shaded region = 55 - 8 = 47 cm²
