Find the missing length in the right triangle.
Answer:
10 ft
Step-by-step explanation:
By using the pythagorean theorem, we know that leg1 squared plus leg2 squared is equal to hypotenuse squared.
[tex]6^2+8^2=?^2\\36+64=?^2\\100=?^2\\10=?[/tex]
Answer: 10ft
Step-by-step explanation:
Pythagorean Theorem- In a right triangle, a²+b²=c² where: (image attached)
a=6ft ; b=8ft
6ft²= 36ft ; 8ft²= 64ft
36+64=100ft
√100= 10ft

How do you solve for a variable?
A. Use the alphabet
B. Displacement
C. Get it by itself
Answer:
C. Get it by itself
Step-by-step explanation:
When solving for a variable, whether it be an inequality, a factor, or an algebraic expression. Getting the specified variable by itself is the most effective and best way to get that answer to your question. The other two answers here do not make any sense whatsoever.
Simplify the algebraic expression (8x + 16y)/2 + 4(x - y)
It's 8x + 16y/2 + 4x - 4y :))
Answer:
8x+4y
Step-by-step explanation:
Distribute:
=4x+8y+(4)(x)+(4)(−y)
=4x+8y+4x+−4y
Combine Like Terms:
=4x+8y+4x+−4y
=(4x+4x)+(8y+−4y)
=8x+4y
Answer:
=8x+4y

A highway department is studying the relationship between traffic flow and speed. The following model has been hypothesized. where traffic flow in vehicles per hour vehicle speed in miles per hour The following data were collected during rush hour for six highways leading out of the city. Traffic Flow () Vehicle Speed () 1257 36 1329 45 1227 30 1336 50 1349 55 1124 25 a. Use the data to compute the coefficients of this estimated regression equation (to decimals). Enter negative value as negative number. (Create the variable first using Data/Transform
Answer:
ŷ = 0.1286X - 123.2175 ;
R = 0.9465
R² = 0.8958
Step-by-step explanation:
Given the data:
Traffic Flow, X : ()
1257
1329
1227
1336
1349
1124
Vehicle speed, Y () :
36
45
30
50
55
25
The estimated regression equation using a linear regression calculator is given thus:
ŷ = 0.1286X - 123.2175
According to the general linear regression formula :
y = mx + c
Where ; y = predicted variable (vehicle speed)
x = predictor variable (traffic flow)
Slope, m = 0.1286
Intercept, c = 123.2175
The correlation Coefficient, R = 0.9465, This depicts a strong positive relationship between traffic flow and vehicle speed.
The Coefficient of determination, R² = 0.9465² = 0.8958 ; This means about 89.5% of variation in Vehicle speed can be explained by the regression line.
Alex has 100. He spends 3/10of it on candies. He spends one-seventh of what's left on colour pencils. How
much money is Alex left with?
Answer:
$60
Step-by-step explanation:
3 tenths of 100 is 30
1 * 10 is 10
100 - 30 + 10
= 100 - 40
= $60

Which of the following is most likely the next step in the series ?
Answer:
A
Step-by-step explanation:
The colour keeps switching from red to blue to red, and red was last in the series. Therefore, a blue pattern should be next in the series.
Each time, a new hand is added to the pattern. Therefore, we add a hand.

What is the volume of a prism if the area of its cross-section is 2 m² and its length is 7 m?
Answer:
14m^3
Step-by-step explanation:
Volume of the prism = base area * height
Given
Area of the cross section = 2m^2
Length = 7m
Substitute
Volume of the prism = 2 * 7
Volume of the prism = 14m^3
Hence the volume of the prism is 14m^3

5x + 3y = -8
Solve by elimination
Answer:
y = -6, x =2
Step-by-step explanation:
To solve by elimination, you have to line both equations up together. Then, you multiply both equations until one variable is removed.
2x+y = -2
5x + 3y = - 8
There are many different ways to solve an elimination problem, but generally you should look for the simplest route. Here, I would multiply the top equation by -3.
-6x -3y = 6
5x +3y = -8
Imagine you are adding the two equations together. You end up with
-x = -2
Then solve for x. In this situation, it is fairly simple. Take out a factor of -1.
x = 2
Finally, choose one of your beginning equations and plug your new-found x value back into the equation.
2(2) +y = -2
4 + y = -2
y = -6
Fill in the blank to make the two fractions equivalent.

Answer:
16
Step-by-step explanation:
28/7 = 4

16/28 = 4/7
Given that 7x – 4y = 6
Find x when y=9
Answer:
6
Step-by-step explanation:
Substitute y for 9: 7x - 36 = 6
Add 36 to both sides: 7x = 42
Divide both sides by 7: x = 6
It's 6, do you need something more simplified?
