Answer:
The value of t is 22
Step-by-step explanation:
Let us solve the question
In any triangle
∵ The sum of the measures of the interior angles of a triangle is 180°
∵ The angle of triangles are ∠1, ∠2, and ∠3
∴ m∠1 + m∠2 + m∠3 = 180°
∵ The three angles of the triangle are 2t, 3t, and 70°
∴ m∠1 = 2t
∴ m∠2 = 3t
∴ m∠3 = 70°
→ Substitute them in the rule above
∴ 2t + 3t + 70° = 180°
→ Add the like terms
∵ (2t + 3t) + 70 = 180
∴ 5t + 70 = 180
→ Subtract 70 from both sides
∵ 5t + 70 - 70 = 180 - 70
∴ 5t = 110
→ Divide both sides by 5
∴ t = 22
∴ The value of t is 22
If x = 1 is a zero of the polynomial 3+ kx^2 + 2 ,find the value of k.
Plz it's urgent.
Answer:
k = i√ 5 , -i√ 5
Step-by-step explanation:
3 + kx^2 + 2 = ?
3 + k(1)^2 + 2 = ?
5 + k(1)^2 = ?
5 + k^2 = ?
k^2 = -5
k = i√ 5 , -i√ 5
Given that f(x) = x2 – 12x + 27 and g(x) = x – 9, find (f.g)(x) and express
the result in standard form.
Step-by-step explanation:
[tex]f(x) = {x}^{2} - 12x + 27 \\ g(x) = x - 9 \\ (f \times g)(x) = ( {x}^{2} - 12x + 27)(x - 9) \\ (f \times g)(x) = {x}^{3} - 9 {x}^{2} - 12 {x}^{2} + 108x + 27x - 243 \\ (f \times g)(x) = {x}^{3} - 21 {x}^{2} + 135x - 243[/tex]

The faces of an eight-sided solid are labeled 1 through 8. Each
number has an equal chance of being rolled. Two of these solids
are rolled. What is the probability that an odd number is rolled on
both solids?
Answer:
The probability that an odd number is rolled on both solids is [tex]\frac{1}{4}[/tex].
Step-by-step explanation:
Consider the provided information.
For the 8 sided dice the total number of outcomes = 64.
The favourable outcomes i.e odd numbers on both the solid = 16
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (1,7), (1,8)
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (2,7), (2,8)
(3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (3,7), (3,8)
(4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (4,7), (4,8)
(5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (5,7), (5,8)
(6,1), (6,2), (6,3), (6,4), (6,5), (6,6), (6,7), (6,8)
(7,1), (7,2), (7,3), (7,4), (7,5), (7,6), (7,7), (7,8)
(8,1), (8,2), (8,3), (8,4), (8,5), (8,6), (8,7), (8,8)
We know that [tex]\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability of odd on both solid}=\frac{16}{64}[/tex]
[tex]\text{Probability of odd on both solid}=\frac{1}{4}[/tex]
Hence, the probability that an odd number is rolled on both solids is [tex]\frac{1}{4}[/tex].

Answer:
[tex]-\frac{5}{4}[/tex]
Step-by-step explanation:
The slope of a graph is the rate of change between two points. To find the slope in a graph you use: [tex]\frac{rise}{run}=\frac{y}{x}[/tex]
The y goes down by 5 and right by 4 so it'll be [tex]-\frac{5}{4}[/tex]
Also: If the line is going down the slope is always negative and vise versa
Miriam wants to paint her room green. She makes a mixture of 50% yellow paint and 50% blue paint to create the color she likes. What type of change occurs when she mixes the paint? A chemical change B phase change C physical change D solution change
Answer:
A chemical change
Step-by-step explanation:
Since in the question it is mentioned that the Miriam wants to paint her room green so she makes a mixture of yellow paint 50% and the blue paint 50% so here the change that arise at the time when she mixed the paint is the chemical change as the two paints are mix together that means chemical together to develop a chemical change
So the first option is correct

What is the average rate of change from x = 0 to x = 2?
-4
-8
1
5
Answer:
The average rate will be: -4
Hence, option A is correct.
Step-by-step explanation:
Given the interval
0 ≤ x ≤ 2
From the graph, it is clear that:
at x₁ = 0, f(x₁) = 3
at x₂ = 2, f(x₂) = -5
Using the formula to determine the average rate of change:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [-5 - 3] / [2-0]
= -8 / 2
= - 4
Therefore, the average rate will be: -4
Hence, option A is correct.

Answer:
x=2
Step-by-step explanation:
Alright for this type of problem the line CE is proportional to line FG meaning that the length of line CE is two times the length of EG. What we want to do is set up an equation that will help us solve for x. The equation would be
18-4x=6x-7 but because line CE is two time greater than line FG we have to multiply the side of EG by 2 so the new equation is
18-4x=12x-14 Now we can began to solve
step 1 : subtract 18 to each side
-4x=12x-32
step 2; subtract 12 from each side
-16x=-32
step 3: divide each side by -16
x=2

Joy delivered 450 newspapers in 3 hours how many can she deliver in 4 hours
Step-by-step explanation:
Time in hours is directly proportional to the number of newspapers.
3 hours = 450 newspapers
=> 4 hours = 450 * (4/3) = 600 newspapers.
Hence Joy can deliver 600 newspapers in 4 hours.

[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given the expression:
[tex]\frac{n+3}{2n-6} \div \frac{n+3}{3n-9}[/tex]
We are to find the quotient as shown:
[tex]= \frac{n+3}{2n-6} \div \frac{n+3}{3n-9} \\\\= \frac{n+3}{2n-6} \times \frac{3n-9}{n+3} \\\\= \frac{n+3}{n+3} \times \frac{3n-9}{2n-6}\\\\= 1 \times \frac{3(n-3)}{2(n-3)}\\\\= 1 \times \frac{3}{2} \\\\= \frac{3}{2}[/tex]
Hence the correct answer is [tex]\frac{3}{2}[/tex]

A wire is first bent into the shape of a square. Each side of the square is 9cm long. Then the wire is unbent and reshaped into a rectangle. If the length of the rectangle is 13cm, what is its width
Answer:
5 cm
Step-by-step explanation:
the perimeter of a square with sides of 9 cm is 36 cm so the rectangle must have the same perimeter
if the length of the rectangle is 13cm, its opposite side is also 13cm
add 13 + 13 to get 26
let 'n' = width of rectangle
perimeter = 26 + n + n
36 = 26 + 2n
2n = 10
n = 5
If the length of the rectangle is 13 cm then the width of the rectangle will be equal to 5 cm.
What is the perimeter?A shape's perimeter is the whole distance encircling it. It is the perimeter or length of the contour of any two-dimensional geometric body. The circumference of several figures could be compared based on the measurements.
As per the information given in the question,
Length of the side of the square = 8 cm
Then, use the formula of the perimeter of the square = 4 × side
= 4 × 9 = 36 cm
The length of the rectangle = 13 cm
Use the formula of the perimeter of the rectangle,
P = 2(l + w)
36 = 2(13 + w)
36 -26 = 2w
w = 10/2
w = 5 cm

K/3+4-5k=-2k what is the answer???
Answer:
Solve for k by simplifying both sides of the equation, then isolating the variable.
Exact Form: k = 3/2
Decimal Form: k = 1.5
Mixed Number Form: k = 1 1/2
Hope this helps!
Answer:
k = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{k}{3}[/tex] + 4 - 5k = - 2k
Multiply through by 3 to clear the fraction
k + 12 - 15k = - 6k
- 14k + 12 = - 6k ( add 14k to both sides )
12 = 8k ( divide both sides by 8 )
k = [tex]\frac{12}{8}[/tex] = [tex]\frac{3}{2}[/tex]
