If M is in the interior of ∠RTD, m∠RTM = 40°, and m∠RTD = 65°, then m∠MTD = .
Answer:
MTD = 75
Step-by-step explanation:
RTD + RTM + MTD = 180
65 + 40 + MTD = 180
105 + MTD = 180
Subtract 105 from both sides.
MTD = 75

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of the angle ∠MTD is equal to 15°.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
Given that point M is in the interior of ∠RTD. Also, the measure of ∠RTM=40°, and ∠RTD = 65°.
Now, since the two angles together form ∠RTD, therefore, we can write,
∠RTD = ∠RTM + ∠MTD
65° = 40° + ∠MTD
∠MTD = 65° - 40°
∠MTD = 15°
Hence, the measure of the angle ∠MTD is equal to 15°.

There are two polygons. The larger one has three times as many sides as the smaller one.
Its angle sum is four times as big. How many sides does the smaller polygon have?
Answer:
Step-by-step explanation:
There are two polygons. The larger one has three times as many sides as the smaller one. Its angle sum is four times as big. How many sides does the smaller polygon have? (Need full solution)?
“Three times as many sides” means the larger polygon has a multiple of 3 sides. 3 is the fewest sides any polygon can have, so it has not less than 9 sides.
Its angle sum is four times the smaller one’s. This applies to interior angles.
A triangle’s sum is 180. A square’s is 360. A pentagon’s is 540. Any sum will be a multiple of 180, and equal to the number of sides minus two, then multiplied by 180.
A hexagon has 6 sides, so 4×180=720 degrees sum. That part fits the triangle, but we know that can’t be the answer because 3×3=9.
So start at 9.
7×180÷4 can’t be a multiple of 180. What we need is a multiple of 3 which is 2 greater than a multiple of 4.
18 fits that description.
The 18-gon’s interior sum is 16×180=2880, divide that by 4 to get 720, which is the hexagon’s sum.
18÷6=3, so we have a solution. The smaller polygon can be a hexagon.
We should check the next one though. Multiples of 3: 21, 24, 27, 30, 33, 36, 39, 42 (every 4th multiple of 3 will be 2 more than a multiple of 4).
So the 30-gon:
28×180=5040
5040÷4=1260
1260÷180=7
7+2=9
9×3=27
Off by 3.
The 42-gon:
((((((42–2)×180)÷4)÷180)+2)×3)=36
Off by 6. It will keep getting farther away, so we have a unique solution.

Answer:
7. Slope = -5
Y-intercept = -3/4
8. Slope = 1/4
Y-intercept = 5
Step-by-step explanation:
y = mx + b
Slope = m
Y-intercept = b
Write the equation of the line fully simplified slope-intercept form. help
Answer:
y = 4x -8
Step-by-step explanation:
The y intercept is -8 so our b term for y = mx + b is 8.
The line goes up 4 y values every one x value to the right
Answer:
y = 3x - 8
Step-by-step explanation:
To write the equation of the line in slope-intercept form, or y = mx + b, we have to find the y-intercept (b) and the slope(m).
To find the y-intercept, look at the graph at find where the line intercepts the y-axis. On this graph, the line intercepts at y = -8. Now we know the value of b.
To find the slope, look at the rise over run between two points. The line goes up by 3 every time it goes over 1. this means that our slope is 3.
Now we can input the values of the slope and the y-intercept into the equation.
y = 3x - 8

The base of an isosceles triangle is a third as long as the two equal sides (each, not
combined). Write the perimeter of the triangle as a function of the length of the base.
Answer:
The perimeter is 7b
Step-by-step explanation:
An isosceles triangle has exactly two sides of the same length. Suppose we have an isosceles triangle with the base as the unequal side length of b.
The perimeter of the triangle is:
P = x + x + b = 2x + b
Being x the two equal side lengths.
It's given the base b of the triangle is one-third of any of the other sides, that is:
b = 1/3 x
Or, equivalently:
x = 3b
Thus, the perimeter of the triangle is:
P = 2x + b = = 2(3b) + b
P = 6b + b = 7b
The perimeter is 7b

The answer is x = 6.
Step-by-step explanation:
The middle line is 2, and the leg is [tex]\sqrt{13}[/tex]. We can use the pythagorean theorem and use [tex]\sqrt{13}[/tex] as the hypotenuse and have 2 be a leg.
[tex]a^{2} + b^{2} = c^{2} \\\\2^{2} + b^{2} = \sqrt{13}^{2}[/tex]
[tex]4 + b^{2} = 13\\\\b^{2} = 9\\b = 3[/tex]
Since we know one of the bottom parts of x is 3, and the other triangle is the same as the on we solve, we do 3 + 3 which is 6. 6 is equal to x.

Step-by-step explanation:
The question is to combine the equations, so we should add them.
- 2x -4y = -26
+ - 3x -3y = - 12
(same signs add, different signs subtract)
-5x -7y = -38
(in the question there are two boxes at the side of the eqaution you should put (+)sign there as youre adding them)
If this question was supposed to be subtracted it would give a while different ans)
Consider the scale drawing and actual drawing of an office.
A smaller rectangle has a length of 2.5 inches and width of 1.5 inches. A larger rectangle has a length of 5 yards and width of 3 yards.
Compare the scale drawing to the actual drawing. What information is needed to find the area?
1. The scale factor is
.
2. The area of the scale drawing is
.
3. To find the area of the actual drawing, multiply the area of the scale drawing by the
of the scale factor.
a)Scale factor is 72.
b)The area of the scale drawing is 3.75 square inches.
c)To find the area of the actual drawing, multiply the area of the scale drawing by 5184.
Length of the smaller rectangle =2.5inches
Width of the smaller rectangle = 1.5inches
So, the area of the smaller rectangle = 2.5*1.5 = 3.75 square inches.
Length of larger rectangle = 5 yards
Width of larger rectangle =3 yards
So, the area of the larger rectangle = 15 square yards = 15*36*36 = 19440 inches.
What is the scale factor?The scale factor is the factor by which the dimension of an object is enlarged.
a)Scale factor = dimension of the larger rectangle/ corresponding dimension of the smaller rectangle
Scale factor = 5 yards/ 2.5 inches
as we know that 5 yards equals 180 inches
So, scale factor = 180/2.5 = 72
b)The area of the scale drawing = 3.75 square inches.
c)Area of actual drawing/ area of scale drawing = 19440/3.75 = 5184
So, to find the area of the actual drawing, multiply the area of the scale drawing by 5184.
therefore, a)Scale factor is 72
b)The area of the scale drawing is 3.75 square inches.
c)To find the area of the actual drawing, multiply the area of the scale drawing by 5184.

Maya will deposit $1,650 in an account that earns 5% simple interest every year. Her brother, James, will deposit $1,600 in an account that earns 8% interest compounded annually. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Compare and contrast the two siblings' accounts after four year
Answer:
Step-by-step explanation:
Step one:
given data
Maya
P=$1650
r=5%= 0.05
t= 4 years
The simple interest expression is
A=P(1+rt)
A=1650(1+0.08*4)
A=1650(1+0.32)
A=1650(1.32)
A=1650*1.32
A=$2178
James
P=$1600
r=8%= 0.08
t=4years
The compound interest expression is
A=P(1+r)^t
A=1600(1+0.08)^4
A=1600(1.08)^4
A=1600*1.360
A=$2176
After 4 years Mayas' balance is $2178
After 4 years James' balance is $2176
the difference is =2178-2176=$2
