The actual rate of the mortgage is 5.27%.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Since, we're taking two mortgages for a total of $100,000 for 30 years,
Now, we can find the actual rate of the mortgage by finding the weighted average of the two rates.
Hence, The weights in this case will be the proportion of loan taken at each rate;
We have
Rates Weights Rates × Weights
4.15 0.80 4.15 x 0.80 = 3.32
9.75 0.20 9.75 x 0.20 = 1.95
Hence, The actual rate of the mortgage is,
⇒ 3.32 + 1.95
⇒ 5.27%.

Step-by-step explanation:
Consider the figure below. Please help!!!!!
Answer:
B. T<-4, -2>, r(90°, O)
Step-by-step explanation:
Point A' is 4 units left and 2 units down from point A, so the translation is T<-4, -2>.
Segment C"D" is on the -x axis, 90° counterclockwise from segment C'D' on the +y axis. Since rotation angles are measured the same way other angles are measured (positive is CCW), the rotation is +90° about the origin.
The congruence transformation that maps the quadrilateral ABCD to A''B''C''D'' is [tex]T_{ < -4, \, -2 > } \circ T_{90^{\circ}}, origin > (ABCD)[/tex] which corresponds with the option B.
B. [tex]T_{ < -4, \, -2 > } \circ T_{90^{\circ}}, origin > (ABCD)[/tex]
What is a congruent transformation?A congruent transformation, which is also a rigid transformation is one in which the size and shape of the original figure is preserved.
The coordinates of the vertices of the quadrilaterals ABCD and A'B'C'D' indicates that the transformation from the quadrilateral ABCD to the quadrilateral A'B'C'D' is a translation of 4 units to the left and 2 units downwards, which can be expressed as T<-4, -2>
The side D'C' in the quadrilateral A'B'C'D' is vertical while the side D''C'' in the quadrilateral A''B''C''D'' is horizontal and due to the order of the letters D'' and C'' in D''C'' arranged from left to right suggesting a 90° counterclockwise rotation about the origin, which is a T90°, origin
The congruence transformation that maps ABCD to A''B''C''D'' therefore is the option B, [tex]T_{ < -4, \, -2 > }\circ T_{90^{\circ}}, origin > (ABCDE)[/tex]

Daniella is drawing plans for a garden, measured in feet, which is shown below on the coordinate plane. Daniella has two vertices of the garden at points (Negative3, Negative 1) and (4, Negative 1). On a coordinate plane, points (negative 3, negative 1) and (4, negative 1) are plotted. At which points should Daniella have the other two vertices in order to make the area of her garden 35 square feet? (Negative 3, 1) and (4, 1) (Negative 3, 2) and (4, 2) (Negative 3, 3) and (4, 3) (Negative 3, 4) and (4, 4)
Answer:
d
Step-by-step explanation:
We know that the length of the garden is 4 - (-3) = 7 feet, the answer is (Negative 3, 5) and (4, 5).
What are vertices?A vertex is a point in geometry where two or more curves, lines, or edges intersect.
As a result of this definition, vertices are the points where two lines intersect to form an angle, as well as the corners of polygons and polyhedra.
Let's assume that the other two vertices are at points (a, b) and (c, d). The area of the garden can be calculated as follows:
Area = Length × Width
35 = 7 × (b - (-1)) [since the width is the distance between the y-coordinates of the vertices]
Simplifying the above equation, we get:
b - (-1) = 5
b = 4
So, one of the vertices should be at (a, 4) and the other at (c, 4). Since the garden is symmetrical about the x-axis, the y-coordinate of the missing vertices is 1 more than the y-coordinate of the given vertices. Hence, the other two vertices should be at (−3, 5) and (4, 5).
Therefore, the answer is (Negative 3, 5) and (4, 5).

Puppy A weighs 8 pounds which is about 25% of its adult weight what will be the adult weight of a puppy A
Answer:
Step-by-step explanation:
Let x be the adult weight of a puppy A
25% of x = 8 pounds
[tex]\frac{25}{100}*x=8\\\\ x=\frac{8*100}{25}\\\\ =8*4=32pounds\\[/tex]
Final answer:
To calculate the adult weight of Puppy A, divide the current weight of 8 pounds by 0.25 since 8 pounds is 25% of the adult weight. The adult weight of Puppy A is 32 pounds.
Explanation:
The student is asking how to find the adult weight of Puppy A, given that its current weight is 25% of its adult weight. To solve this, we need to use the concept of percentages. If Puppy A currently weighs 8 pounds and this represents 25% of the adult weight, we can set up a proportion:
25% (current weight) / 100% (adult weight) = 8 pounds / adult weight
To find the adult weight, we divide 8 pounds by 25% (0.25 in decimal form):
Adult weight = 8 pounds / 0.25
Adult weight = 32 pounds
Therefore, the adult weight of Puppy A is expected to be 32 pounds.

An arithmetic sequence is represented in the following table. Enter the missing term of the sequence.
x y
1 221
2 217
3 213
4 209
82 ?
When you subtract the y values you find that each increase in x decreases y by 4.
X is going from 4 to 82 which is 78 units.
78 x 4 = 312
Subtract 312 from the last y value:
209 - 312 = -103
The answer is -103
Answer:
When x = 82, y = -103
Step-by-step explanation:
So an arithmetic sequence is a sequence whose terms differ by a constant value. To find the value of the [tex]n^{th}[/tex] term we need to form an equation for the sequence.
Equation to the sequenceFirst we need to find the difference between the values of the sequence. In this case the difference is -4:
217 - 221 = -4, 209 - 213 = -4
So the equation is:
[tex]n^{th}[/tex] term = -4n + c
Now we need to find the c, so we substitute the [tex]n^{th}[/tex] term and the term number and solve the equation:
221 = (-4 x 1) + c
221 = -4 + c
c = 225
So the final equation is:
[tex]n^{th}[/tex] term = -4n +225
Finding the 82nd termNow all we need to do is substitute into the equation and find the answer:
[tex]n^{th}[/tex] term = (-4 x 82) + 225
[tex]n^{th}[/tex] term = -328 +225
[tex]n^{th}[/tex] term = -103
Which graph shows a dilation of the rectangle with a scale factor of 2?
the first one is part of the question not an answer iption
Answer:
The graph that shows the dilation of the rectangle in the attached figure
Step-by-step explanation:
we know that
A dilation is a non rigid transformation that produce similar figures
If two figures are similar, then the ratio of its corresponding sides is proportional
In this problem we have that the scale factor is equal to 2
Remember that
If a scale factor is greater than 1, then the dilation is a enlargement
To find out the dimensions of the dilated figure multiply the original dimensions by the scale factor
The original dimensions of rectangle are

There are white, blue, and red boats in a marina. Five-sixths of the boats in the marina are white,
2
5
of the remaining boats are blue, and the rest are red. If there are 12 red boats, how many boats are in the marina?
Final answer:
To find the number of boats in the marina, we use the information given about the proportion of white, blue, and red boats. By setting up an equation and solving for the total, we find that there are 222 boats in the marina.
Explanation:
To find the number of boats in the marina, we need to start with the information given. The problem tells us that five-sixths of the boats in the marina are white, and then 25 of the remaining boats are blue. The rest of the boats are red, with a total of 12 red boats.
We can start by finding the fraction of boats that are red. Since five-sixths are white, the remaining fraction of boats that are not white is one-sixth. We know that 25 boats are blue, so if we subtract this from the one-sixth, we are left with the fraction that represents the red boats.
Let's set up an equation to solve for the total number of boats:
1/6 - 25 = 12
Simplifying the equation, we have:
1/6 = 12 + 25
1/6 = 37
Multiplying both sides of the equation by 6, we get:
1 = 37*6
1 = 222
Therefore, there are a total of 222 boats in the marina.

Find the value of x in the triangle shown below
a. √8
b. √32
c. 32
d. 8
Answer:
5.65685424949 or 5.66
Step-by-step explanation:
In a right-angled triangle, the longest side/leg is called the hypotenuse.
The formula to solve for the hypotenuse is:
hyp^2= side^2+side^2
If the hypotenuse of the triangle is already given then we have to solve for a side.
The formula to solve for the side is:
side^2= hyp^2-side^2
This formula to solve for the side is the opposite of solving for the hypotenuse which is the longest side/leg of the right-angled triangle.
In this question we have to solve for the side.
There are two sides in this triangle. Let's name those sides side a and side b. Side a is already given.
hyp= 9
side a = 7
side^2 = hyp^2-side^2
side b = 9^2 - 7^2
side b = 81 - 49
side b = 32
side b = √32
side b= 5.65685424949. to 2 decimal places -> 5.66
How fast can a car going that traveled 330 and 1/3miles in 5 and 1/4 hour show your work
Answer: [tex]62.92 \frac{mi}{h}[/tex]
Step-by-step explanation:
If we are asked about how fast a car is going, this means we are asked about its velocity [tex]v[/tex], which is defined by the relation between the traveled distance [tex]d[/tex] and time [tex]t[/tex]:
[tex]v=\frac{d}{t}[/tex]
Where:
[tex]d=(330+\frac{1}{3}) mi=330.33 mi[/tex] is the traveled distance
[tex]t=(5+\frac{1}{4}) h=5.25 h[/tex] is the time
Solving the equation with the given information:
[tex]v=\frac{330.33 mi}{5.25 h}[/tex]
Finally:
[tex]V=62.92 \frac{mi}{h}[/tex] This is the car's velocity
Answer:
The speed of the car is 77.72 miles per hour
Step-by-step explanation:
To find out how fast is a car travelling when it traveled 330 and 1/3 miles in 4 and 1/4 hours following formula will be used
Speed= [tex]\frac{Distance}{Time}[/tex]
Total distance = 330 and 1/3
= 330+ 0.33
= 330.33 miles
Total time = 4 and 1/4
= 4 + 0.25
= 4.25 hrs
putting the values in equation we get speed of car
Speed= [tex]\frac{330.33}{4.25}[/tex]
Speed = 77.72 miles per hour
So the speed of the car is 77.72 miles per hour

Rewrite each expression as a product of two fractions, one of which is equal to 1
(a) 10^5/10^2 = 1000
(b) x^2/x^6 = 1/(x^4)
(c) x^4y/xy^8 = x^3/y^7
a) To rewrite the expression 10^5/10^2 as the product of two fractions, we can write it as (10^5)/(10^2) = (10 * 10 * 10 * 10 * 10) / (10 * 10).
Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have 10 as a common factor, we can simplify further to get (10 * 10 * 10 * 10 * 10) / (10 * 10) = 10 * 10 * 10 = 1000.
Therefore, the equivalent and simpler expression for 10^5/10^2 is 1000.
(b) For the expression x^2/x^6, we can rewrite it as (x * x) / (x * x * x * x * x * x).
Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have x as a common factor, we can simplify further to get (x * x) / (x * x * x * x * x * x) = 1 / (x * x * x * x).
Therefore, the equivalent and simpler expression for x^2/x^6 is 1/(x^4).
(c) To rewrite the expression x^4y/xy^8 as the product of two fractions, we can write it as (x * x * x * x * y) / (x * y * y * y * y * y * y * y).
Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have x and y as common factors, we can simplify further to get (x * x * x * x * y) / (x * y * y * y * y * y * y * y) = (x^3) / (y^7).
Therefore, the equivalent and simpler expression for x^4y/xy^8 is x^3/y^7.

Answer: 30+x+y
Step-by-step explanation:
Commutative Property of Addition : a+b= b+a , where a and b are any arbitrary numbers.Given : Number of CDs sold by friend on first day = 14
Number of CDs sold by friend on next day = x
Total CDs sold by friend = 14 +x
Number of CDs sold by you on first day = 16
Number of CDs sold by you on next day = y
Total CDs sold by you = 16+y
The expression that shows the total number of CDs sold both days =
Total CDs sold by friend + Total CDs sold by you
= 14 +x+ 16+y
= 14 +(x+ 16)+y
= 14 +(16+x)+y [By Commutative Property of Addition.]
= 14+16+x+y
= 30+x+y
Hence, the expression that shows the total number of CDs sold both days :
30+x+y
