triangle abc is similar to triangle def. the lengths of the sides of triangle abc are 5, 8, and 11. what is the length of the shortest side of triangle def if its perimeter is 60?
Answer:
The shortest sides is 12.5.
Step-by-step explanation:
5 + 8 + 11 = 24
60 / 24 = 2.5
So 2.5 * 5 = 12.5
The length of the shortest side of triangle DEF is 12.5 units.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbolΔ.
Since triangle ABC is similar to triangle DEF, the ratio of the corresponding sides of the two triangles is the same.
Let x be the length of the shortest side of triangle DEF.
The length of the shortest side of triangle DEF, x, is in the same ratio to the length of the shortest side of triangle ABC, 5, as the other sides of triangle DEF are in relation to the other sides of triangle ABC.
The perimeter of triangle ABC is:5 + 8 + 11 = 24
The perimeter of triangle DEF is 60.
So 60 / 24 = 2.5
So the length of the shortest side: 2.5 x 5 = 12.5
Therefore, the length of the shortest side of triangle DEF is 12.5 units.

The expression 200 - 16t2 models the height in feet of an object that falls from the initial height of 200 feet t seconds after being dropped. Find the height of the object after 0.75 seconds. Make sure and include the units of feet in your answer for full credit. Round your answer to the nearest hundredth place.
Answer:
Concept: Modeling expressions
We are given the equation [tex]200 - 16 {t}^{2} [/tex]We want to find the time after 0.75 seconds given that t is represented in seconds.Hence we do [tex]200 - 16(0.75)^{2} [/tex]Hence we get the answer to 191 feetThe height of the object that falls after 0.75 seconds given that t is represented in seconds is 191 feet.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The expression 200 - 16t^2 models the height in feet of an object that falls from the initial height of 200 feet t seconds after being dropped.
We need to find the time after 0.75 seconds given that t is represented in seconds.
The expression is given
[tex]200 - 16t^2[/tex]
time t = 0.75

Find the value of g7) for the function below.
g(x)= 7/8x -1/2
Answer:
[tex]g(7) = \frac{45}{8} \\ \: or \: \\ 5 \frac{5}{8} [/tex]
Step-by-step explanation:
We would just apply the 7 in g(7) as all the x
g(x)= 7/8x - 1/2
g(7)= 7/8(7) -1/2
[tex] \frac{7}{8} \times \frac{7}{1} = \frac{49}{8} [/tex]
Simplify
g(7)= 49/8 -1/2
Multiply -1/2 by 4/4 to get the denominators the same
[tex] \frac{49}{8} - \frac{4}{8} = \frac{45}{8} [/tex]

. Caroline had 400 stamps in her collection. 1 10 th of them were Indian stamps, Onethird of the remaining stamps were from Europe and 100 stamps were from Africa. The rest were from the United States of America. How many American stamps were there?
Answer:
So 400 stamps
African---> 100
Indian------> 1/10 x 400
= 40
European---> 400-40=360
1/3 x 360
= 120
so 120+40+100= 260

Find the lower quartile of the following numbers: 1, -2, 7, 9, 0, 10
Answer:
0
Step-by-step explanation:
The first step is to locate the median.
The median is the middle value of the numbers arranged in ascending order. If there is no exact middle value then it is the average of the numbers either side of the middle.
- 2, 0, 1, 7, 9, 10 ← ascending order
↑ middle
median = [tex]\frac{1+7}{2}[/tex] = [tex]\frac{8}{2}[/tex] = 4
The lower quartile Q₁ is the middle value of the numbers to the left of the median, that is
- 2, 0, 1
↑
lower quartile Q₁ = 0
Use the Rectangle to the right for Questions 1-4
Answer:
1. 34
2. 56
3. 112
4. 68
Step-by-step explanation:
For the first one, the angle measuring 112 is a vertical angle to angle 9 so angle 9 is also 112. So 180-112 (180 because the measure of every triangle is 180.) is 68. Then you divide 68 by 2 and get 34 because the angles 1 and 8 measure the same.
For the second one, you would first find the measure of angle 10 by subtracting 180-112 again and getting 68 (the measure of a flat line is 180.) Then you would get 112 for the remaining angles and divide that by two because once again, the two angles are the same measure. So 112 divided by 2 is 56.
For the third one, I already stated that the measure of angle 9 is 112.
And finally, for the fourth one, I also previously stated that the measure of angle 10 is 68.

Which statement best describes the triangle formed by joining the points A(-3,6),B(-11,2),C(-4,-2)
Answer:
Isosceles triangle
Step-by-step explanation:
Length of side AB = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
= [tex]\sqrt{(-11+3)^2+(2-6)^2}[/tex]
= [tex]\sqrt{64+16}[/tex]
= [tex]\sqrt{80}[/tex]
= 4[tex]\sqrt{5}[/tex]
Length of BC = [tex]\sqrt{(-4+11)^2+(-2-2)^2}[/tex]
= [tex]\sqrt{49+16}[/tex]
= [tex]\sqrt{65}[/tex]
Length of AC = [tex]\sqrt{(-3+4)^2+(6+2)^2}[/tex]
= [tex]\sqrt{1+64}[/tex]
= [tex]\sqrt{65}[/tex]
Since, AC = BC, ΔABC will be an isosceles triangle.

Determine the nth term rule and find the 45th term for the arithmetic sequence with a10=1 and d-6
Answer: -209
Step-by-step explanation:
Formula for arithmetic progression
= a + (n - 1)d
Since a10 = 1 and d = -6
a10 = a + 9d
a + 9(-6) = 1
a - 54 = 1
a = 1 + 54
a = 55
Therefore, 45th term = a + (n - 1)d
= a + (45 - 1)d
= a + 44d
= 55 + 44(-6)
= 55 - 264
= -209
The actual length (1) of a rectangle is 122 inches. Use the scale drawing of the rectangle to find the actual width (w).
W 1.8 in.
6.1 in.
A
3.38 in.
B
36 in
С.
67.77 in
D
219.6 in
Answer:
B. 36 in.
Step-by-step explanation:
Length of the scale drawing (L) = 6.1 in.
Width of the scale drawing (W) = 1.8 in.
Actual length = 122 in.
Using the scale drawing we can apply the rules of three of proportions to find the actual width.
Thus, set the ratio of the scale drawing length to width, equal to the ratio of the actual length to width:
[tex] \frac{6.1}{1.8} = \frac{122}{x} [/tex]
Cross multiply
[tex] 6.1*x = 122*1.8 [/tex]
Divide both sides by 6.1
[tex] x = \frac{122*1.8}{6.1} [/tex]
[tex] x = 36 [/tex]
Actual width of the rectangle = 36 in.

At the beginning of an environmental study, a forest covered an area of 1500 km . Since then, this area has decreased by 2.4% each year. Lett be the number of years since the start of the study. Let y be the area that the forest covers in km². Write an exponential function showing the relationship between y and t.
Answer:
[tex]y = 1500(0.024)^t[/tex]
Step-by-step explanation:
Given
[tex]a = 1500km[/tex] -- initial area
[tex]b = 2.4\%[/tex] -- rate
[tex]t = time[/tex] --- (years)
Required
Represent as an exponential function
An exponential function has the form:
[tex]y = ab^t[/tex]
Where
[tex]a = initial\ value[/tex]
[tex]b = rate[/tex] and [tex]b \ne 1[/tex]
[tex]t= time[/tex]
Substitute values for a and b, we have:
[tex]y = 1500 * (2.4\%)^t[/tex]
Convert percentage to decimal
[tex]y = 1500 * (0.024)^t[/tex]
[tex]y = 1500(0.024)^t[/tex]
Hence, the exponential function that represents the scenario is: [tex]y = 1500(0.024)^t[/tex]
