Can someone please help me it’s urgent
Answer:
8.5 in
Step-by-step explanation:
You are solving for the hypotenuse right? So you would use this formula:
c = square root a^2+b^2
the c is the hypotenuse (long side of a right triangle) and a will be 4 and b will be 7.5. substitute the numbers in, solve, and you get 8.5 inches!
x = square root 4^2 + 7.5^2
x = square root 16 + 56.25
x = square root 72.25
x = 8.5 inches

Step-by-step explanation:
If y varies directly as x and y = 15 when x=-5, find y when x= 7.
A. -21
B. 21
C. 105
D. -35
Answer:
A. -21
Step-by-step explanation:
y varies directly as x
y = kx
----------------------
y = 15 when x = -5
Find k, the constant of variation
15 = k(-5)
Divide both sides by -5
-3 = k
k = -3
------------------------------
y when x= 7
using k = -3
y = -3(7)
y = -21

If 2/3x - 1 = 4, then x =?
PLEASE HELP
x = 15/2
Step-by-step explanation:
Step 1: Add 1 to both sides.
2/3x − 1 + 1 = 4 + 1
2/3x = 5
Step 2: Multiply both sides by 3/2.
(3/2) * (2/3x) = (3/2) * (5)
x = 15/2
can an obtuse triangle have a 90 degree angle?
Answer:
No
Step-by-step explanation:
Obtuse has an angle that is greater than 90 degrees. To be obtuse the angle must be 91 and up. Right triangles are 90-degree angles. Acute triangles have an angle that is less than 90. So, 89 and below.
I hope I answered your question correctly.

Draw a picture of a line and a point that is not on the line. Draw in the shortest distance from the point to the line, What do you notice about the line connecting the point and the line to the original line?
Answer: The line connecting the point and the line is perpendicular to the original line.
Step-by-step explanation:
(Forgot the name but there is also a theorem stating that the shortest distance between a point and a line is the one that is perpendicular)
how can we rewrite the slope formula,so that we have point-slope form
The ratio of hot dogs to hamburgers on a barbeque table is 6:4. If there are 36 hot dogs on the table then how many hamburgers must be there?
Answer: 24
Step-by-step explanation:
6 hot dogs for every 4 hamburgers
6*6 = 36
36 hot dogs for every ? hamburgers
since 6*6 equals 36, do 4*6
4*6 = 24
so 24 hamburgers
I can’t guarantee that this is right but I think it is
hopefully it’s helpful
Is it possible for a triangle to have a 54 degree angle and a 126 degree angle? Explain why or why not.
Answer:
No
Step-by-step explanation:
Those are only 2 angles and they already equal 180, Every single triangle has a sum of 180 and if you already hit 180 with only 2 out of the 3 points, it's not possible
Answer:
No
Step-by-step explanation:
No, because the 3 angles of a triangle have to add up to 180 degrees. The given 2 angles already add up to 180 degrees leaving no room for the missing angle.

if A(2;2) and B(-3;4), determine the equation of AB, in the form y=mx+c
Answer:
[tex]y = -\frac{2}{5}x + \frac{14}{5}[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + c[/tex]
In which m is the slope and c is the y-intercept(value of y when x = 0).
A(2;2) and B(-3;4)
When we have two points, the slope is the change in y divided by the change in x. So
Change in y: 4 - 2 = 2
Change in x: -3 - 2 = -5
Slope: [tex]m = \frac{2}{-5} = -\frac{2}{5}[/tex]
So
[tex]y = -\frac{2}{5}x + c[/tex]
A(2;2)
When [tex]x = 2, y = 2[/tex]. We use this to find c.
[tex]y = -\frac{2}{5}x + c[/tex]
[tex]2 = -\frac{2}{5}(2) + c[/tex]
[tex]c = 2 + \frac{4}{5} = \frac{10}{5} + \frac{4}{5} = \frac{14}{5}[/tex]
So
[tex]y = -\frac{2}{5}x + \frac{14}{5}[/tex]

d more than 342 is the same as 90
write this sentence as an equation.
Answer:
342 + D = 90
Step-by-step explanation:
We can deduce the following from the statement;
- D is added to 342 so as to make it greater.
- The resulting value is the same as 90 i.e equal in value to 90.
Translating the word problem into an algebraic expression, we have;
342 + D = 90

The following are six observations collected from treatment 1, four observations collected from treatment 2, and five observations collected from treatment 3. Test the hypothesis at the 0.05 significance level that the tre atment means are equal.
a) state the null and the alternate hypotheses
b) What is the decision rulec).
c) Compute SST, SSE, and SS total
d) Complete an ANOVA table
e) State your decision regarding the null hypothesis

Answer:
Since the calculated value of F=0.20 does not fall in the critical region
F ≥ = 3.481 we reject the alternate hypothesis and accept the null hypothesis and conclude that there is no difference between the means of the 3 treatments.
Step-by-step explanation:
As the sample size are different we can run anova in the excel.
Part a)
The null and alternate hypotheses are
H0: μ1=μ2=μ 3 against the claim Ha: Not all three means are equal
The significance level ∝ is chosen to be 0.05
Part b)
The critical region is F≥ F(0.05,5,9) = 3.481
Part c) SST, SSE, and SS total
SS total= 144.933
SSE= 129.8333
SST= 15.1

Graph the system of Inequalities presented here on your own paper, then use your graph to answer the following questions:
y > 3x + 10
y<3/4x-1
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (8, 10) Included in the solution area for the system? Justify your answer mathematically. (4 points)
(10 points)
Answer:
Step-by-step explanation:
Given the inequalities as
y>-2x+3
y<1/2x-2
Graph the inequalities on the graph tool
The solution is points in the shaded area such as (2,2),(4,4),(4,2),(2,-2),(2,-4)
The point (-2,3) is not included in the solution area because it is located in the un-shaded area.
Mathematically, taking points (-2,3) into the inequality
y>-2x+3
3>-2(-2) +3
3>4+3
3>7---------------------not correct because 3<7
