Answer:
x = 25
∠A = 148°
Explanation:
the lines are parallel lines, meaning that there are alternate angles next to ∠A and ∠B. since the line is straight, the sum of the alternate angle as well as ∠A 180°. this is also true for ∠B, so we know that ∠A and ∠B are equal.
6x - 2 = 4x + 48
(add 2 to both sides) 6x = 4x + 50
therefore, 2x = 50 and x = 25.
now, we can find ∠A by substituting 25 into the equation:
6x - 2
= 150 - 2
= 148°

What is the perimeter of the triangle? (Round to the nearest tenth)
Answers
Answer:
P = 43.3
Step-by-step explanation:
sin 38° = EF/18
EF = 18·sin 38°
EF = 11.1
to find DF:
sin 90°/18 = sin 52°/DF
1/18 = .79/DF
DF = 14.2
Given the side lengths, determine whether the triangle is acute, right, obtuse, or not a triangle.
3, 9, 10
Answers
Explanation:
Assign the sides by length with c being longest
If (a^2)+(b^2)>(c^2) it’s acute
If (a^2)+(b^2)=(c^2) it’s right
And if (a^2)+(b^2)<(c^2) it’s obtuse
Since (3^2)+(9^2)=9+81=90
And 10^2=100 we know that (a^2)+(b^2)<(c^2) so it’s obtuse

A school administrator claims that the average GPA of
the senior class is 3.53. You think that the average GPA
is greater than that, so you select a random sample of
100 seniors and calculate their average GPA. The
sample mean GPA is 3.70.
Using technology, you simulate selecting 100 SRS of
size n = 100 from a population of seniors for which the
mean GPA is 3.53. This dotplot shows the results.
O In one simulated SRS of 100 students, the average
GPA was = 3.45.
In one simulated SRS of 100 students, the
population mean GPA was u = 3.45.
There is a 1 out of 100 chance that the population
mean GPA is = 3.45.

Solve the system of equations by the addition method.
8x+y=-2
4x-y=-14
Answers
[tex]8x + y = -2[/tex]
[tex]4x - y = -14[/tex]
To solve this via the addition method, we just need the two equations together; that means that we will create a new equation where the terms on the left side of both equations are added together and are set equal to the sum of the terms on the right side of both equations:
[tex](8x + y) + (4x - y) = (-2) + (-14)[/tex]
[tex]8x + y + 4x - y = -2 - 14[/tex]
[tex](8x + 4x) + (y - y) = -16[/tex]
[tex]12x + 0 = -16[/tex]
[tex]x = \frac{-16}{12}[/tex]
[tex]x = \frac{-4}{3}[/tex]
Now that we have solved for one term, we can plug this value into either equation to get the value for the other:
[tex]4x - y = -14[/tex]
[tex]4(\frac{-4}{3}) - y = -14[/tex]
[tex]\frac{-16}{3} - y = -14[/tex]
[tex]\frac{-16}{3} + 14 = y[/tex]
[tex]\frac{26}{3} = y[/tex]
This means the solution to the system of equations is [tex](-\frac{4}{3}, \frac{26}{3})[/tex]
Answer:
Step-by-step explanation:
8x + y = -2
4x - y = 14
12x = 12
x = 1
8 + y = -2
y = -10

Karl is making a pot of chili. The recipe calls for StartFraction 3 Over 8 EndFraction cup of chili powder, but Karl only wants to use half as much so it won’t be so spicy. How much chili powder should Karl use?
Answers
Answer:
Karl should use 3/16 cup of chili
Step-by-step explanation:
From the question, we are told that the recipe calls for 3/8 to be used
However, Karl wants to use half of this
what we have to simply do here is to divide what was stated in the recipe to be used by 2
We can either divide by 2 or simply multiply by 1/2
Mathematically, we have this as;
3/8 * 1/2 = 3/16 of a cup
2 1/3 · 3 1/2

The ratio of one side of ΔABC to the corresponding side of similar ΔDEF is 3:5. The perimeter of ΔDEF is 48 inches. What is the perimeter of ΔABC?
Answers
Answer:
28.8 inches
Step-by-step explanation:
We solve the above question using Proportion
The ratio of one side of ΔABC to the corresponding side of similar ΔDEF is 3:5.
ΔABC/ΔDEF = 3/5
Hence,
The perimeter of ΔDEF is 48 inches.
Let the perimeter of ΔABC = x inches
3/5 = x/48
Cross Multiply
5x = 48 × 3
x = 48 × 3/5
x = 28.8 inches
The perimeter of ΔABC is 28.8 inches

D. X = 130 in.
Step-by-step explanation:
a² +b² =c² (Pythagorean theorem)
50² + 120²=c²
2,500 + 14,400 =c²
16,900 = c²
√16900 = √c²
130 = c
X = 130 in.
The scale on a map of Virginia shows that 1 inch represents 45 miles. the actual distance from Richmond, Va, to Washington, D.C., is 110 miles. on the map, how many inches are between the two cities?
Answers
Answer: 2.44 inches
Step-by-step explanation:
Since the scale on a map of Virginia shows that 1 inch = 45 miles while the actual distance from Richmond, Va, to Washington, D.C., is 110 miles.
The number of inches that are between the two cities will be represented by x. Therefore,
1/x = 45/110
Cross multiply
45x = 110
x = 110/45
x = 2.44 inches
The Distance between the two cities on the map is 2.44 inches
p-5 = 19
answer step by step & explain
Answers
Answer:
Step-by-step explanation:
Very simple.
p - 5 = 19
So to take out the -5 on that side, you must also do the same thing to the other side. So adding 5 in one side of the equal sign would mean you have to do the same thing on the other side of the equal sign.
SO:
p-5 +5 = 19+5
p = 24
26-5=19
(19+5 is also 26 so you can check your work that way)
