Answer:
a=2, b = 1, m=9
Step-by-step explanation:
i. 7 = 2a+3 -----> 4=2a---------> a=2
ii. -1 = 2b-3 -------> 2 = 2b ------> b = 1
iii. 2(3)+3 = m -------> 6+3 = m -------> m=9
Hope this helps!!! :D

Answer:
[tex]m\angle CAB=65^\circ[/tex]
Step-by-step explanation:
Angles and Lines
It's convenient to recall two basic principles of angles:
The sum of internal angles in a triangle is 180°
Two linear angles are supplementary, i.e. they sum 180°.
Angles ABC and CBD are linear. Since we know the measure of angle CBD, thus the measure of angle ABC is 180°-6x.
Now focus on the triangle. The sum of its internal angles is:
x + 40 + 3x + 10 + 180 - 6x = 180
Simplifying:
-2x + 230 = 180
Subtracting 230:
-2x = -50
Dividing by -2:
x = -50 / (-2) = 25
x = 25°
Now find the measure of angle CAB
[tex]m\angle CAB=x+40=25+40=65[/tex]

12(−1.4m+0.4)=
0.7m + 0.2
-0.7m + 0.2
2.8m + 0.8
-2.8m + 0.8
Answer:
m = 0.28571428571
or 0.29(to the nearest tenth)
Step-by-step explanation:
First, distribute
12(−1.4m+0.4)=
-16.8m + 4.8 =
Now move the constant to the right.
-16.8m + 4.8 =
-16.8m = -4.8 =
Now divide,
-16.8m = -4.8 =
m = 0.28 or 0.29

Answer:
V = 63.62
Step-by-step explanation:
Answer: 63.62 cubic inches
Step-by-step explanation:
REMEMBER :: VOLUME OF CYLINDER = πr^2h
r= 1.5 in.
h= 9 in.
V= π (1.5)^2 (9)
V= π (2.25) (9)
V= π (20.25)
V~63.6172512...
nearest hundredth = 63.62 cubic inches
On a coordinate plane, 2 rectangles are shown. Rectangle A B C D has points (negative 10, 8), (negative 4, 8), (negative 4, 4), (negative 10, 4). Rectangle W X Y Z has points (4, negative 4), (7, negative 4), (7, negative 12), (4, negative 12). Are rectangles ABCD and WXYZ congruent? Why or why not? Yes, all right angles were preserved. Yes, both rectangles have an area of 24 square units. Yes, a 180° rotation about the origin will map ABCD to WXYZ.

Answer: The length of JK is 10.5 m
Step-by-step explanation:
Find the circumference C= dπ
C = 12π
C= 37.7
There are 360 degrees in a circle's circumference, so you can find the length of the arc by using the ratio of the arc to the whole circumference.
Multiply the Circumference by 100/360 (or 5/18 × 37.7)
The arc is 10.5 m

Answer:
Graph B
Step-by-step explanation:
First you solve them which will give you,
X-intercept = (-4,0)
Y-intercept = (0,6)
Slope 3/2x
equation for this: y = 3/2x + 6
So graph B is the only option like this.

You have a rectangle with the perimeter of 150 cm. One side length is
represented by 2x+4. The other side is 30 cm. What is the value of the side length represented by 2x+4?
side length represented by 2x+4?*
Answer:
x=20.5
Step-by-step explanation:
Perimeter of rectangle = 2(L+B)
L- Length and B - Breadth
150 = 2( 2x+4 +30)
150÷2 = 2x + 34
75 = 2x + 34
2x = 75 -34
2x = 41
x = 20.5
Your salary is $65,788. If you work fifty 40-hour weeks in a year, what is your hourly wage?
Answer:
$31.63/hr
Step-by-step explanation:
Given parameters:
Yearly salary = $65788
Number hours worked per week = 40hrs
Unknown:
Hourly wage = ?
Solution:
The hourly wage is found by dividing the yearly salary by the total number of hours worked per year.
There are 52 weeks in a year;
Number of hours worked per year = 52 x 40 = 2080hrs
Hourly wage per year = [tex]\frac{65788}{2080}[/tex] = $31.63/hr
