26 is what % of 65.
Answers
Suppose that 65 is the 100%, then we can find the percentage that is 26 from 65 using a rule of three:
[tex]\begin{gathered} 65\rightarrow100\% \\ 26\rightarrow x\% \\ \Rightarrow x=\frac{26\cdot100}{65}=\frac{2600}{65}=40 \\ x=40\% \end{gathered}[/tex]therefore, 26 is 40% of 65

[tex]-2 The correct option is BThe graph shows f(x) (1/2) and it transitions, g(x). Witch discribes the translation of (x) to g (x)
Answers
The translation from f(x) to g(x) is a translation of 4 units up (option A)
Explanation:Given:
Graph of f(x) =(1/2)^x ang g(x)
To find:
the transformation from f(x) to g(x)
To determine this, we will pick points on the x-axis and compare the result on the y axis for both graphs
when x = 0
f(x) = 1
g(x) = 5
The difference in value = 5 - 1 = 4
when x = 5
f(x) = 0
g(x) = 4
The difference in value = 4 - 0 = 4
We see the difference in value for the y is constant. This means to get g(x), we will add 4 units to the y coordinates of f(x)
The translation from f(x) to g(x) is a translation of 4 units up (this is because the value of y is positive and on the graph g(x) moves above f(x) on the vertical)
Exam Instructions.Question 11 of 20 :Select the best answer for the question11. Which of the following statements about trapezoids is true?O A. Both pairs of opposite sides are parallel.O B. One pair of opposite sides is parallel.O C. Opposite angles are congruent.OD. Opposite sides are congruent.+ 5Mark for review (Will be highlighted on the review page)
Answers
Consider that trapezoid is a type of quadrilateral, which has one pair of opposite sides unequal but parallel, and the other pair of opposite sides are non-parallel.
Now, read the options carefully. We have to mark the option that is always true for a trapezoid.
Option A:
It is not necessary for a trapezoid to have both pairs of opposite sides as parallel. Only one pair being parallel is required for a quadrilateral to be a trapezoid.
Option B:
As discussed above, the statement is correct for every trapezoid.
Option C:
This is not a necessary condition for a trapezoid. There exist some trapezoids that don't have the opposite angles congruent.
Option D:
Again, this is not a necessary condition for a trapezoid. Since one pair of sides is non-parallel, the other pair must be unequal.
Therefore, it can be concluded that option B is the correct choice.
Help find the unit prices while rounding to the nearest cent.
Answers
It is clear that brand A has the lower unit price hence it is the better buy.
Which is the better buy?We know that the better buy has to do with the commodity that would give us the least unit price for the item. Hence we must have to look at the unit price of each of the items before we decide the better buy. The unit price is the price of only one spoon.
In the first case;
Unit price = $2.17/42 = $0.05
In the second case;
Unit price = $3.97/48
= $0.08

6 of the people in Bob's family like dolphins and 6 like polar bears. 3 people like both dolphinsand polar bears. How many people like dolphins but not polar bears?
Answers
ANSWER
3
EXPLANATION
To answer this question we can make a Venn diagram. Each circle will represent the people who like dolphins and the people who like polar bears. We know that 3 people like both, so there are 3 people in the area shared by both circles. If 6 people like dolphins and 6 like polar bears, knowing that already 3 people are in the area shared by both circles, in the individual area of each circle there will be 3 people:
So, we can see that there are 3 people out of the 6 that like dolphins that also like polar bears.
Hence, there are 3 people that like dolphins but not polar bears.

• (a)The radius of the cone is 8cm.
,• (b)The base area of the cone is 200.96 cm².
,• (c)The volume of the cone is 1004.8 cm³.
Explanation:
(a)Radius
Using the right triangle above, we find the radius of the cone using the Pythagorean theorem.
[tex]\begin{gathered} 17^2=15^2+r^2 \\ r^2=17^2-15^2 \\ r^2=64 \\ r^2=8^2 \\ r=8\text{ cm} \end{gathered}[/tex]The radius of the cone is 8cm.
(b)Base Area of the cone
The base of the cone is a circle.
In part(a), the radius of the circle was found to be 8 cm.
[tex]\begin{gathered} \text{ The area of a circle}=\pi r^2 \\ =3.14\times8^2 \\ =200.96\;cm^2 \end{gathered}[/tex]The base area of the cone is 200.96 cm².
(c)Volume of the cone
The volume of a cone is calculated using the formula:
[tex]V=\frac{1}{3}\pi r^2h[/tex]Substitute the values: π=3.14, h=15cm, r=8cm
[tex]\begin{gathered} V=\frac{1}{3}\times200.96\times15 \\ =1004.8\;cm^3 \end{gathered}[/tex]The volume of the cone is 1004.8 cm³.
Frederick needs to borrow $3000 for a down payment on a new car. His uncle decided to loan him the money as a 4.7 % loan. Frederick doesn't want to pay more than $423 in interest. How many years does Frederick have to pay back the loan? years
Answers
Given:
The initial money = $3000
Rate = 4.7% = 0.047
Frederick doesn't want to pay more than $423 in interest.
So, we need to find the number of years
Assume simple interest rate:
[tex]\begin{gathered} I=P\cdot r\cdot t \\ I=423 \\ P=3000 \\ r=0.047 \\ \\ 423=3000\cdot0.047\cdot t \\ 423=141\cdot t \\ \\ t=\frac{423}{141}=3 \end{gathered}[/tex]so, the number of years = 3 years
Use the figure below to complete the following problem.Given:ZH= 2x + 60Z T= x+ 30HALT is aT=
Answers
Answer: 60 degrees
The figure there is a parallelogram
< H = 2x + 60
< T = x + 30
Therefore, supplementary angles is 180 degrees
< H + < T = 180
2x + 60 + x + 30 = 180
Collect the like terms
2x + x + 60 + 30 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
Divide both sides by 3
3x/3 = 90/3
x = 30
Since < T = x + 30
Hence,
< T = 30 + 30
< T = 60 degrees

Given that on day 15 the balance was $0 and on day 16 the balance is $100, then we have:
[tex]\begin{gathered} \text{slope:} \\ m=\frac{y_2-y_1}{x_2-x_1} \\ \Rightarrow m=\frac{100-0}{16-15}=100 \\ \text{for point (15,0) and slope m=100:} \\ y-y_0=m(x-x_0) \\ \Rightarrow y-0=100(x-15) \\ \Rightarrow y=100x-1500 \end{gathered}[/tex]we have that the relation function for this period is B(x)=100x-1500. Then for x=21 we have the following:
[tex]\begin{gathered} B(x)=100x-1500 \\ B(21)=100\cdot21-1500=2100-1500=600 \\ \end{gathered}[/tex]therefore, using the relation function, we have that B(21) = 600.

[tex]\begin{gathered} B(17)=100\cdot17-1500=1700-1200=200 \\ B(18)=100\cdot18-1500=1800-1500=300 \\ B(19)=100\cdot19-1500=1900-1500=400 \\ B(20)=100\cdot20-1500=2000-1500=500 \end{gathered}[/tex]Find the half-life (in hours) of a radioactive substance that is reduced by 5 percent in 75 hours.half life = ___ include units
Answers
Let's list down the given information.
Time = 75 hours
Final Value = reduced by 5% = 95%
To get the half life, the formula is:
[tex]t=\frac{\ln 0.5}{k}[/tex]Before we can get the half-life, we need to get the value of k or the decay rate first. The formula is:
[tex]k=\frac{\ln A}{t}[/tex]where A is the final value in percentage and t = time. Since we have this information above, let's plug it in the formula and solve for k.
[tex]k=\frac{\ln0.95}{75}=-0.0006839105918[/tex]Now that we have the value of "k", let's solve for "t" using the formula stated above as well.
[tex]t=\frac{\ln 0.5}{k}=\frac{\ln 0.5}{-0.0006839105918}=1013.51[/tex]Hence, the half life of the radioactive substance is approximately 1,013.51 hours or 1,013 hours and 30 minutes.

The height of the building is 308 ft

solve the following system of equations using substitution.y=2x-2-4x-y=26solve for x and y m
Answers
system equation is
y = 2x - 2
-4x - y = 26
we will be solving this equation simultaneously by using substitution method
y = 2x - 2 --------- equation 1
-4x - y = 26 ------- equation 2
substiute y = 2x - 2 into equation 2
equation 2 becomes
-4x - (2x - 2) = 26
-4x - 2x + 2 = 26
collect the like terms
-4x -2x = 26 - 2
x(-4 - 2) = 24
x(-6) = 24
-6x = 24
to find x, divide both sides by -6
-6x/-6 = 24/-6
x = 24/-6
x = -4
to find y put x = -4 into equation 2
-4x - y = 26
-4(-4) - y = 26
16 - y = 26
collect the like terms
-y = 26 - 16
-y = 10
divide both sides by -1
-y/-1 = 10/-1
y = -10
the answer is x= -4 and y = -10
Using elimination method for the following equation
5x + y = 24
-5x - 4y = -56
in elimination method, you need to eliminate one of the variables before you can get the other variable
so let us eliminate x first

-5x -4y = - 56
since the second equation have a negative value of 5x then, we need to sum up the two equations to eliminate x
5x + (-5x) + y +(-4y) = 24 + (-56)
0x + y - 4y = 24 -56
-3y = -32
divide both sides by -3
-3y / -3 = -32/-3
y = 32/3
The answer is 32/3
