The height of △XYZ is the distance from point Yto XZ←→. Find the area of the triangle. Round your answer to the nearest tenth, if necessary.
Answer:
10
Step-by-step explanation:
A triangle is a polygon shape with three sides. There are different types of triangles such as scalene, obtuse, equilateral, isosceles etc.
The area of a triangle is given by:
Area = (1/2) * base * height
For triangle XYZ, the base = |XZ| and the height = |AY|
We can calculate the base and height using the formula for the distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Therefore:
[tex]Base=|XZ|=\sqrt{(0-(-2))^2+(2-6)^2} =\sqrt{20} \\\\Height=|AY|=\sqrt{(3-(-1))^2+(6-4)^2}=\sqrt{20}[/tex]
Area = (1/2) * base * height = (1/2) * √20 * √20 = 10.
i need help i’m not good at math
Answer:
c
Step-by-step explanation:
to write in scientific notation, the number has to be less than 10 but more than one
so for the given number let’s say there’s a decimal at the end
49,010,000.
to move the decimal to the right of 4, we’re moving 7 places
that’s why once the number is
4.901
we write a x10^7 after because you have to move the decimal 7 places to the right to get it back to the original number
Luke is going to a carnival that has games and rides. Each game costs $3.50 and each ride costs $4.50. How much would Luke have to pay if he wanted to play 8 games and go on 10 rides? How much would Luke have to pay if he wanted to play x x games and go on y y rides?
Answer:
28$ games and 45$ for rides so 73$
Step-by-step explanation:
Answer:
he would pay $73.40 for 8 games and 10 rides
Step-by-step explanation:
multiply 3.50 by 8 since it costs him 3.50 per each ride. when calculated u get 28.40.then when calculated multiply 4.50 by ten since that is how much each ride costs. the total should be 45.00. now add 28.40 to 45.00 to get ur answer

Match the pairs of equivalent expressions.
Answer:
Step-by-step explanation:
1). [tex](4t-\frac{8}{5})-(3-\frac{4}{3}t)=(4t+\frac{4}{3}t)+(-\frac{8}{5}-3)[/tex]
[tex]=(\frac{12}{3}t+\frac{4}{3}t)-(\frac{8}{5}+\frac{15}{5})[/tex]
[tex]=\frac{16}{3}t-\frac{23}{5}[/tex]
2). 7t - 22
3). 5(2t + 1) + (-7t + 28) = 10t + 5 - 7t + 28
= (10t - 7t) + 33
= 3t + 33
4). [tex]\frac{16}{3}t-\frac{23}{5}[/tex]
5). [tex](-\frac{9}{2}t+3)+(\frac{7}{4}t+33)=(-\frac{9}{2}t+\frac{7}{4}t)+(3+33)[/tex]
[tex]=(-\frac{18}{4}t+\frac{7}{4}t)+36[/tex]
[tex]=(\frac{-18+7}{4})t+36[/tex]
[tex]=-\frac{11}{4}t+36[/tex]
6). [tex]-\frac{11}{4}t+36[/tex]
7). 3(3t - 4) - (2t + 10) = 9t - 12 - 2t - 10
= (9t - 2t) - ( 12 + 10)
= 7t - 22
8). 3t + 33
Therefore, equivalent expressions are,
a). [tex](4t-\frac{8}{5})-(3-\frac{4}{3}t)=\frac{16}{3}t-\frac{23}{5}[/tex]
b). 7t - 22 = 3(3t - 4) - (2t + 10)
c). [tex](-\frac{9}{2}t+3)+(\frac{7}{4}t+33)=-\frac{11}{4}t+36[/tex]
d). 5(2t + 1) + (-7t + 28) = 3t + 33
There are 8 boys and 6
girls on a soccer team. The
coach will select a captain
and then select a co-
captain. What is the
probability of selecting a
boy and then a girl?
Answer:
the probability of selecting a boy and then a girl is 24 ÷ 91
Step-by-step explanation:
The computation of the probability of selecting a boy and then a girl is as follows:
The probability in the case when a boy is picked up
= 8 ÷ (8 + 6)
= 8 ÷ 14
The probability in the case when a girl is picked up
= 6 ÷ (8 + 6)
= 6 ÷ 14
Now the final probability is
= 8 ÷ 14 × 6 ÷ 13 ( without replacement)
= 24 ÷ 91
hence, the probability of selecting a boy and then a girl is 24 ÷ 91

A car lot owner is trying to get rid of this year's inventory to make room for the new vehicles. He paid $25,599 for a red truck. If he sells it to a customer for $22,000, what mark down percentage did he use?
Answer:
14%Step-by-step explanation:
Step one
given data
Cost price of vehicle= $25,599
Selling price of vehicle= $22,000
Required
The percentage discount in the price
Step two:
% discount= cost price-selling price/cost price*100
% discount= 25,599-22,000/25,599*100
% discount= 3599/25,599*100
% discount= 0.140*100
% discount= 14%
The mark down percentage use is 14%

We can use the pythagorean theorem to solve this, incase you forgot, this is the pythagorean theorem:
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex]a = side \\ b = side \\ c = diagonal[/tex]
So lets solve using the pythagorean theorem.
[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {12}^{2} + {b}^{2} = {13}^{2} \\ 144 + {b}^{2} = 169 \\ \frac{- 144 \: \: \: \: \: = - 144}{ {b}^{2} = \sqrt{25} } \\ b = 5[/tex]
Therefore, x equals 5.

Answer:
y=−8x+53
Step-by-step explanation:
I think... I'm not sure so I'm sorry if its wrong
Answer: Here is an explanation of how to get the answer.
Step-by-step explanation:
It tells you the slope is -8, so you know your equation will look like this:
y = -8x + b,
where b is the intercept. You also are given a point that is on the line, so that is an x and a y value that are a solution to the equation. You can plug those in and solve for b.
5 = -8(6) + b
53 = b
So, your equation is y = -8x + 53

C=2 4 6 3 6 9 4 8 12 find the determinant and inverse of c
Answer:
The determinant of C is zero and does not have inverse.
Step-by-step explanation:
Let [tex]C = \left[\begin{array}{ccc}2&4&6\\3&6&9\\4&8&12\end{array}\right][/tex], since it is a matrix with 3 rows and 3 columns, we can determine its determinant by the Sarrus' rule:
[tex]\det(C) = \left|\begin{array}{ccc}2&4&6\\3&6&9\\4&8&12\end{array}\right|[/tex]
[tex]\det(C) = (2)\cdot (6)\cdot (12)+(3)\cdot (8)\cdot (6)+(4)\cdot (4)\cdot (9)-(4)\cdot (6)\cdot (6)-(3)\cdot (4)\cdot (12)-(2)\cdot (8)\cdot (9)[/tex]
[tex]\det (C) = 0[/tex]
Since the determinant of C is equal to zero, then we conclude that C does not have an inverse according to the following definition of inverse matrix. That is:
[tex]C^{-1} = \frac{1}{\det(C)}\cdot adj(C)[/tex] (1)
Where [tex]adj(C)[/tex] is the adjugate matrix of C, defined as the transpose of the cofactor matrix of C.
The result of this expression is undefined due to the determinant.
The erosion rate of a coastline is approximately 3 feet per year. if erosion continues at the current rate, how many years will it take for the shoreline to erode 15 feet to a grass line and then another 24 feet to a tree line? Explain.
it takes 5 years for the shoreline to erode 15 feet to a grass line
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The erosion rate of a coastline is approximately 3 feet per year
if erosion continues at the current rate, how many years will it take for the shoreline to erode 15 feet to a grass line
Let us formulate the equation
Let x be the number of years for 15 feet.
3/1=15/x
Apply cross multiplication
3x=15
Divide both sides by 3
x=5
which is 5 years,
adding 24 ft means, it would take 13 yrs.
3 x 8 = 24
Hence it takes 5 years for the shoreline to erode 15 feet to a grass line
