Answer:
37 degrees
Step-by-step explanation:
1. m∠CBA = 71+45 = 116 degrees
2. m∠CBA = m∠CDA because of the quadrilateral property of opposite sides.
3. m∠CBA + m∠CDA = 2*116 = 232.
4. Total angle measure of a quadrilateral is 360 degrees, so m∠BAD + m∠BCD = 360-232 = 128 degrees.
5. m∠BAD = m∠BCD = 128/2 = 64 degrees
6. m∠BAC = m∠BAD - m∠CAD = 64 - 27 = 37 degrees

A sign on the road says " Speed limit, 60 miles per hour. Let s be the speed of car.Write an inequality that matches the information on the sign
Answer: s ≤ 60
Step-by-step explanation:
The common inequality signs include:
> which is greater than
< which is less than
= which is equal to
≥ which is greater than or equal to
≤ which is less than or equal to
Since the speed limit is 60 miles per hour, it simply means that the speed limit is less than or equal to 60 miles per hour. This will be:
s ≤ 60
The above means the speed is less than or equal to 60 miles per hour

c = 18 * 3.14
c = 56.52 decimal approximation
Pls, help me with this math question
Answer:
Perimeter [tex]\sqrt{26}+\sqrt{5}+\sqrt{10}+\sqrt{17}[/tex] units. Area 12 square units.
Step-by-step explanation:
Perimeter: total distance around the figure.
Distance Formula: the distance between points [tex]\left(x_1,y_1\right) \text{ and } \left(x_2,y_2\right)[/tex] is
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]AB=\sqrt{(6-1)^2+(2-1)^2}=\sqrt{25+1}=\sqrt{26}[/tex]
[tex]BC=\sqrt{(5-6)^2+(4-2)^2}=\sqrt{1+4}=\sqrt{5}[/tex][tex]CD=\sqrt{(2-5)^2+(5-4)^2}=\sqrt{9+1}=\sqrt{10}[/tex][tex]DA=\sqrt{(1-2)^2+(1-5)^2}=\sqrt{1+16}=\sqrt{17}[/tex]
The perimeter is the sum of all those segment lengths.
One way to find the area of the figure is to surround it with a rectangle, insert some lines so that the areas you do not want can be found and subtracted from the rectangle's area. (See attached image.)
The area of the large rectangle around the figure is 5 x 4 = 20 square units.
The triangles have areas 1/2 (base) (height):
A. (1/2)(1)(4) = 2 square units
B. (1/2)(3)(1) = 1.5 square units
D. (1/2)(1)(2) = 1 square unit
E. (1/2)(5)(1) = 2.5 square units
Square C. (1)(1) = 1 square unit
Total of all the area you don't want to include:
2 + 1.5 + 1 + 2.5 + 1 = 8 square units
Subtract 8 from the surrounding rectangle's area of 20, and you get the area of the figure is 20 - 8 = 12 square units.
Solve the following system of equations graphically on the set of axes below. Y=-1/2x +1 and y=x-5

(x,y)=(4,-1)
what is the rate of change for y=5.6x+7
Answer:
5.6
Step-by-step explanation:
The equation is put in y = mx + b
where m = slope ( rate of change ) and b = y intercept
5.6 = m and 7 = b
Hence the rate of change for y = 5.6x + 7 is 5.6
hi can someone check my answer bc i really dont think its right
heres the question, theres and image attached as well!
Answer:
19329, you are correct
Step-by-step explanation:
Volume = [tex]\pi * r^{2} * h[/tex]
Volume = [tex]3.14 * (18)^{2} *19[/tex]
Volume= 19329.84
not rounded= 19329
What is the range of the function shown in the graph below?
Answer:
y= -3/2X + 2
Step-by-step explanation:
we get the gradient by picking any two points from the graph( it a linear graph)
using the point:
(x,y)= (-2,5) , (4,-4)
using M= (y2-y1)/x2-x1)
we get our gradient to be -9/6 which is
-3/2
using the equation of a straight line graph which is
y-y1=m(x-x1) and the point (4,-4)
we get
y-(-4)=-3/2(x-4)
----> y+4= -3/2x + 6
make y subject of the formula to take the form
y=mx+c
we get :
y=-3/2x + 2
g + 19 = 38
Explain how to get the answer pls!
In order to find out what g is equal too,u must subtract 19 from both sides of the equation to get
g +19-19=38-19
the nineteens cancel out getting
g=38 -19
g=19

Given an arithmetic sequence described by the formula a= -2(n - 1) + 7 find a^28
Answer:
-47
Step-by-step explanation:
Given the arithmetic sequence described by the formula;
a= -2(n - 1) + 7
To get a28, we will substitute n = 28 into the expression
a28 = -2(28-1)+7
a28 = -2(27)+7
a28 = -54+7
a28 = -47
Hence a28 is -47

A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares. What is the area of the shaded rectangle?
Answer:
Area of Rectangle = 28 cm²
Step-by-step explanation:
Given - A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares.
To find - What is the area of the shaded rectangle?
Solution -
The graph of the rectangle is as follows :
From the diagram, e can see that
Length of Rectangle = 7 units (cm)
Breadth of Rectangle = 4 units (cm)
We know that,
Area of Rectangle = Length × Breadth
= 7 × 4
= 28 cm²
⇒Area of Rectangle = 28 cm²

Answer:
a. east
b. 60 feet per second
Step-by-step explanation:
did this a while ago.
a. -180 is east, 120 is east. the car is traveling east because it is moving positive. read the last sentence of the description.
b. to calculate velocity you do time times position. in this case position is 60 and time is 1 so 60*1 is 60. so it is 60 feet per second.

Step-by-step explanation:
Answer:
28/3
Step-by-step explanation:
Dividing a fraction is the same as multiplying it by the reciprocal.
First, convert 4 and 2/3 to an improper fraction.
You get 14/3. Multiply that by the reciprocal of 1/2 (2/1) to get your answer.
14/3 * 2/1 = 28/3
