Answer:
3/4Step-by-step explanation:
2 2/4 - 1 3/4 = 2 + 2/4 - 1 - 3/4 = (2 - 1) + (2/4 - 3/4) = 1 + (-1/4) = 1 - 1/4 =3/4Which of these equations has no solution? OA) m = 0 OB) m = m = O c) 2m + 1 = m - 2 od m + 4 = m-4
Answer:
OD is the correct answer
Answer:
OD ) m + 4 = m - 4
Step-by-step explanation:
m + 4 = m - 4
m = m - 4 - 4
m = m -8
m -m = - 8
0 ≠ 8
So, this has no solution

Answer:
Step-by-step explanation:

Select ALL sets of numbers that are possible values for x in the inequality, x > -5. { -4 , 2 , 4 } { -6 , -7 , 4 } { 5 , 0 , -4 } { -5 , -12 , -8 }
Answer:
{ -4 , 2 , 4 } and { 5 , 0 , -4 }
Step-by-step explanation:
Given the solution to an inequality expression as x > -5. The values of x are the values that are greater than -5.
The values greater than -5 are the values that falls towards the positive sides of the number line but greater than -5. The numbers are -4, -3, -2, -1, 0 ,1 ,2, 3, 4, 5, 6....
From the given numbers, the correct set of numbers will be { -4 , 2 , 4 } and { 5 , 0 , -4 } since the values are within the range of listed values
9x2 - 52x + 33 = -10x - 16
Quadratic Equation
Answer:
x=7/3 or x=2.33
Step-by-step explanation:
9x^2 - 52x + 33 = -10x - 16
Okay, lets Start by converting this into standard form, which is: ax^2 + bx + c = 0.
Add 10x+16 on both sides of the equation, and simplifying.
9x^2 - 52x + 33 + 10x + 16 = -10x - 16 + 10x + 16
9x^2 - 42x + 49 = 0
Guess What! This equation is a Perfect Square Trinomial.
For a Perfect Square Trinomial, you will be able to take the square root of the first and third terms, and the coefficient of the second term will be twice the square root of the third term. The “sign” of your second term in your answer will be the same as the linear term sign.
So this is (3x*3x) + (3x * -7 * 2) + (7 * 7) = 0
So, we can rewrite this as (3x - 7)^2=0
Now, To solve, We can set each factor equal to 0, and solve.
*Since we have a Perfect Square Trinomial, You will get one solution, or value, for x.*
Add 7 on both sides.
3x - 7 = 0
+7 +7
----------------
3x=7
Divide by 3 on both sides.
3x/3 = 7/3
x=7/3
As a decimal: 2.33...

A rectangular piece of land measures 250 m by 220 m. Each side is to be fenced with 3 rows of wires. What is the length of the wire needed?
Answer:
2,820 m
Step-by-step explanation:
Given that the rectangular piece of land measures 250m by 220 m, the perimeter of the rectangle gives the length of wire required to fence it once.
The perimeter p of a rectangle of length l and width b is given as
p = 2(l + b)
Hence p = 2( 250 + 220)
= 2 * 470
= 940 m
Since each side is to be fenced with 3 rows of wires, the length of wire required
= 3 * 940m
= 2,820 m

Step-by-step explanation:
the sum of angles in a triangle is equal 180°
we have been given that one angle equals yo 90° and the other equals to 45°
let "?" be the unknown angle

? = 180° - (90° + 45°)
? = 180° - 135°

18. State the slope and y-intercept of each linear equations.
a. 6(x + y) = 3(x - y)
b. 2(x + y) = 5(y + 1)
c. 5x + 10y - 20 = 0
Answer:
a. The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0
b. The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]
c. The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2
Step-by-step explanation:
The easiest way to find the slope and y-intercept is to put each equation in the slope-intercept form
That is:
y = mx = c
where m is the slope and c is the y-intercept
Part a:
6(x+y) = 3(x-y)
2(x+y) = x-y
2x + 2y = x - y
3y = -x
[tex]y = \frac{-1}{3}x[/tex]
Comparing this with the general formula, we can conclude that:
The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0
Part b:
2(x+y) = 5(y+1)
2x + 2y = 5y + 5
3y = 2x - 5
[tex]y = \frac{2}{3}x - \frac{5}{3}[/tex]
Comparing this with general formula, we can conclude that:
The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]
Part c:
5x + 10y -20 = 0
10y = -5x + 20
[tex]y = \frac{-1}{2} x+2[/tex]
Comparing this with the general formula, we can conclude that:
The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2
Hope this helps :)

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=62°, and NO = 66 feet. Find the length of MN to the nearest tenth of a foot.
Answer:
140.6 feet
Step-by-step explanation:
In ΔMNO, the measure of ∠O=90°, the measure of ∠N=62°, and NO = 66 feet. Find the length of MN to the nearest tenth of a foot.
Step 1
We have to find Angle M
Sum of angles in a triangle = 180°
M + N + O = 180°
M = 180° - ( N + O)
M = 180° - ( 90° + 62°)
M = 28°
Step 2
We find the length of MN
We solve using Sine rule
MN/sin O = NO/sin M
MN/sin 90 = 66/sin 28
Cross Multiply
MN = sin 90 × 66/sin 28
MN = 140.58 feet
Approximately = 140.6 feet
Paul will roll two standard dice simultaneously. If Event A = both dice are odd and Event B = at least one die is even, which of the following best describes events A and B?
Answer:
Mutually Exclusive
Dependent
Step-by-step explanation:
Given that both events cannot occur at the same time, that is "both dice cannot be odd (event A) if at least one of the dice is even (event B).
Hence, this is MUTUALLY EXCLUSIVE.
Also, given the fact that the occurrence of one event (event A) affects the probability of the other (event B).
Hence, this is DEPENDENT.
