Answer:
15
Step-by-step explanation:
All you have to do is plug in the values into the variables.
[tex](-2)^{4} - (-1)^{\frac{2}{5} }[/tex]
Now evaluate.
[tex](-2)^{4} = 16[/tex]
[tex](-1)^{\frac{2}{5} } = 1[/tex]
Now subtract the two numbers.
16 - 1 = 15
The answer is 15.

Solve the equations by modeling. Draw the steps, using circles for the variables and squares for the numbers. 1) Solve 5x−4 = 3x +8. A. Model. B. Perform the step to have variables (circles) on only one side. C. Write the resulting step. D. Perform the step to have the variables (circles) alone on one side. E. Write the resulting step. F. Divide the variables (circles) and numbers (squares) into equal group
Answer:
x = 2
Step-by-step explanation:
Given the expression 5x−4 = 3x +8, we are to solve for the value of x;
Step 1: Collect the like terms so that the variables are on one side and Constants on the other side
5x - 3x = 8-(-4)
5x - 3x = 8+4
Step 2: Evaluate the expression in both sides
5x-3x = 8+4
2x = 12
Step 3: Divide both sides by 2
2x = 12
2x/2 = 12/2
x = 6
Hence the value of x is 2
A crosstown bus travels 8 kilometers in 45 minutes. What is its average rate of speed
Answer:
10.67 km/hr
Step-by-step explanation:
A crosstown bus travels 8 kilometers in 45 minutes, its average rate of speed is, 10.67 km/hr
What is average?In mathematics, Average is a values which we calculate by dividing sum of values of all the data-set by number of data-sets.
Average = sum of values of all the data-set/number of data-sets
Given that,
A crosstown bus travels 8 kilometers
Time = 45 minutes =45/60 hr = 3/4 hr
Average speed = ?
Average speed = Total distance covered /Total time taken
Average speed = 8 km/(3/4)hr
= 10.6666 km/hr
Hence, The average speed is 10.67 km/hr

Find the m < ABC , need help ASAP
Given :-
AB = AC
Then :-
This triangle is an isosceles triangle .
Let x be the value of ∠CAB . Then, ∠ABC will also have the same value as ∠CAB , since∠CAB and∠ABC are both the opposite base angles of an isosceles triangle .
An equation to find ∠ABC and ∠CAB :-
[tex] = x + x + 60 = 180[/tex]
[tex] = 2x + 60 = 180[/tex]
[tex] = 2x = 180 - 60[/tex]
[tex] = 2x = 120[/tex]
[tex] = x = \frac{120}{2} [/tex]
[tex] = x = 60[/tex]
Which means that the measure of ∠ABC and ∠CAB both are equal to 60°, and this triangle is an equilateral triangle.
Therefore :-
[tex]\color{olive}\bold{m∠ABC\color{hotpink} = 60°}[/tex]
[tex]\large{\underline{\underline{\red{\tt{\purple{\leadsto } GiveN\:\: Figure:-}}}}}[/tex]

[tex]\large{\underline{\underline{\red{\tt{\purple{\leadsto } AnsweR:-}}}}}[/tex]
It is given that AB = AC . Since two sides of the triangle are equal , hence it must be an isosceles triangle .
And we know that in an isosceles triangle two base angles are equal . So ∠ABC = ∠ ACB = 60° .

In a test, 5 marks are given for every correct answer and (-2) marks are given for every incorrect answer. 1) Anjali scored 30 mark. If she got 10 correct answers, how many questions she answered incorrectly? 2) Rohan got 4 correct answers. If he scored (-12) marks in the test, how many questions he answered incorrectly?
Answer:
1. Anjali answered 10 questions incorrectly
2. Rohan answered 16 questions incorrectly
Step-by-step explanation:
1 .The mark given for one correct answer = 5
That means that the mark given for 10 correct answers = 5 × 10 = 50
But Anjali's score = 30
Also, the marks gotten for incorrect answers = 30 - 50 = -20
Mark given for one incorrect answer = -2.
Therefore, number of incorrect answers would be;
= (-20) ÷ (-2)
= 10
•Anjali answered 10 questions incorrectly.
2. Total marks = -12
Number of correct answers = 4
Total marks for correct answers = 4 × 5 = 20
Also, marks for incorrect answers = -2 × Number of incorrect answers
Therefore,
Total marks = Marks for the correct answers + Marks for the incorrect answer
-12 = 20 + (-2) × Number of incorrect answers
-12 - 20 = -2 × Number of incorrect answers
-32 / 2 = Number of incorrect answers
Number of incorrect answers = 16
• Rohan answered 16 questions incorrectly.

How would I find the x-intercept and the y-intercept for the equation: 6x+5y=−60?
Answer:
use the slope intercept form of the equation
y = Mx +b
Step-by-step explanation:
6x+5y = -60
5y = -6x - 60
y = (-6/5)x -12
now just plug in zero for x in that above equation ... that will be the y intercept -12
and plug in zero for y and solve for x
0 = (-6/5)x -12
12= -6/5x
(-5/6)(12) = x
-10 = x

Kaleb has 45 DVD's in his collection and Eileen has 61. If Kaleb buys 4 new DVD's each month and Eileen buys 2 new DVD's each month, after how many months will Kaleb and Eileen have the same amount of DVD's?
Answer: After 8 months they will have equal number of DVD's.
Step-by-step explanation:
Given: Kaleb has 45 DVD's in his collection and Eileen has 61.
Let x= Number of months
If Kaleb buys 4 new DVD's each month and Eileen buys 2 new DVD's each month , then
Total DVD's Kaleb has = 45+4x
Total DVD's Eileen has = 61+2x
When they has equal DVD's , then
[tex]45+4x =61+2x\\\\\Rightarrow\ 4x-2x=61-45\\\\\Rightarrow\ 2x=16\\\\\Rightarrow\ x=\dfrac{16}{2}\\\\\Rightarrow\ x=8[/tex]
Hence, after 8 months they will have equal number of DVD's.

English tends to be ambiguous in statements like this. It is difficult to tell whether we want 5 more than the product, or 7 times the sum. Sometimes punctuation can help make the meaning clear. Assuming the former, a suitable expression is ...
7n +5 . . . . the product of 7 and a number, increased by 5
Write the equation of the line described that passes through (12,-17), perpendicular to y = -3/7x - 5
Answer:
y + 17 = 7/3(x - 12)
General Formulas and Concepts:
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate
y₁ - y coordinate
m - slope
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Perpendicular lines have the negative reciprocal slope of the given line's slope.
Step-by-step explanation:
Step 1: Define
Line: y = -3/7x - 5
Slope m = -3/7
Point (12, -17)
Step 2: Find slope of perpendicular line
Take the negative reciprocal of the original slope.
Slope m = 7/3
Step 3: Write perpendicular line equation
x₁ = 12
y₁ = -17
m = 7/3
y + 17 = 7/3(x - 12)

Simplify ( − 32 ) ⋅ ( 7 x ( − 4 ) ) . Tap for fewer steps... Multiply − 4 by 7 . − 32 ⋅ ( − 28 x ) = x Multiply − 28 by − 32 . 896 x = x Move all terms containing x to the left side of the equation. Tap for fewer steps... Subtract x from both sides of the equation. 896 x − x = 0 Subtract x from 896 x . 895 x = 0 Divide each term by 895 and simplify. Tap for fewer steps... Divide each term in 895 x = 0 by 895 . 895 x 895 = 0 895 Cancel the common factor of 895 . Tap for more steps... x = 0 895 Divide 0 by 895 . x = 0
