Answer: 9 weeks
Step-by-step explanation:
-0.1³ + 0.6x² + 85 = 70
x ≈ 8.21998224
The answer is 9 weeks because you must round 8.22 up to 9. The reason you round up to 9 is because must include the numbers after the decimal in a week, but you cannot have 0.22 weeks, so 0.22 rounds up to 1.

9

Answer:
∠AMC = 76°
Step-by-step explanation:
1) Because ∠YMC = 170°, you need to add 5x+19 (∠YMA) and 5x+1 (∠AMC) to equal the length of ∠YMC:
170 = 5x + 19 + 5x + 1
2) Combine like terms:
170 = 10x + 20
3) Subtract 20 from both sides:
150 = 10x
4) Divide by 10:
x =15
5) Replace x in ∠AMC with 15:
5(15) + 1
6) Multiply:
∠AMC = 76°
The measure of ∠AMC is 76°.
Given that, m∠YMC=170°, m∠YMA=(5x+19)° and m∠AMC=(5x+1)°.
We need to find the value of m∠AMC.
What are adjacent angles?The two angles are said to be adjacent angles when they share the common vertex and side. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. Adjacent angles can be complementary angles or supplementary angles when they share the common vertex and side.
Now, m∠YMA+m∠AMC=m∠YMC
⇒(5x+19)° + (5x+1)°=170°
⇒10x+20=170
⇒10x=150
⇒x=15
So, m∠AMC=5x+1=76°
Therefore, the measure of ∠AMC is 76°.

Romeo paid $380.75 in car repairs. The sales tax rate is 7.5%. Which of the following is a reasonable estimate for the total Romeo paid to repair his car?
Answer:
$354.19
Step-by-step explanation:
The total payment was $380.75 plus 7.5% of that, which can be represented by
(1 + 0.075)r = $380.75, where r is the repair bill before taxes. Then:
1.075r = $380.75, and r = $354.19 (rounded to the nearest cent)
Answer:
the correct answer is actually $410.00
Carlo is building a wooden box that is shaped like a cube. He wants the box to have a volume of 64 cubic inches.What is the area of one face of the box?
Explanation:
Apply the cube root to 64 to get [tex]\sqrt[3]{64} = 64^{1/3} = 4[/tex]
The exponent 1/3 is handy if your calculator doesn't have a cube root button.
This wooden cube has side lengths of 4 inches each.
Each square face will have an area of 4^2 = 4*4 = 16 square inches.

Linear Function A
Points: (–5, –2), (–5, 7)
Linear Function B
Points: (7, –5), (–2, –5)
Function A has
✔ no slope
.
The equation of line A is
✔ x = -5
.
Function B has
✔ a slope of 0
.
The equation of line B is
✔ y = -5
.
here are the answersss
Answer:
Function A has
✔ no slope
.
The equation of line A is
✔ x = -5
.
Function B has
✔ a slope of 0
.
The equation of line B is y= -5
Step-by-step explanation:
i did the online assighnment
The true expressions about functions A and B from the options given are :
Function A has no slope Function B has a slope of 0Equation of line B is y = - 5Function A :
Points: (–5, –2), (–5, 7)
Slope = (7 - (-2)) ÷ (-5 - (-5)) = 9 ÷ 0 = 0
From :
y = bx + c b = slope ; c = interceptWe can obtain c, thus ;
-2 = 0(-5) + c
-2 = c
y = - 2
Function B :
Points:(7, –5), (–2, –5)
Slope = (-5 - (-5)) ÷ (-2 - 7) = 0 ÷ - 9= 0
From :
y = bx + cb = slope ; c = intercept
We can obtain c, thus ;
-5 = 0(7) + c
-5 = c
y = -5

please help !
Answer: x = 3.5
Step-by-step explanation:
We can start by subtracting 5 from both sides:
2x - 5 = 12 - 5 Which will come out to: 2x = 7
Then we divide both sides by 2 so that we can isolate the variable:
2x/2 = 7/2 Which will come out to: x = 3.5

If m1 = 27° and m2 = 25°, what is m3?
Answer: 128 degrees
Step-by-step explanation:
If m1 = 27° and m2 = 25°, what is m3?
27+25=52
180-52=128
that's the simplest way to do it
The measure of m₃ will be;
⇒ m₃ = 128°
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In a triangle;
⇒ m₁ = 27°
⇒ m₂ = 25°
Now,
We know that;
In a triangle, The sum of all interior angle is equal to 180°
Hence, We get;
⇒ m₁ + m₂ + m₃ = 180°
⇒ 27° + 25° + m₃ = 180°
⇒ m₃ = 180 - 52°
⇒ m₃ = 128°
Thus, We get;
⇒ m₃ = 128°

Solve for b.
3-2(b - 2) = 2 - 7b
Answer:
b = -1
Step-by-step explanation:
use distributive property to multiply the -2 with the numbers in the parentheses
3 - 2b + 4 = 2 - 7b
7 - 2b = 2 - 7b
add 2b to both sides
7 = 2- 5b
subtract 2 from both sides
5 = -5b
divide by -5
b = -1
The solution for b is -1.
Let's solve the equation step by step to isolate the variable b:
3 - 2(b - 2) = 2 - 7b
First, simplify the expression inside the parentheses:
3 - 2b + 4 = 2 - 7b
Combine like terms:
7 - 2b = 2 - 7b
Next, let's isolate the terms with b on one side. We can do this by adding 7b to both sides:
7 - 2b + 7b = 2 - 7b + 7b
Simplifying:
7 - 2b + 7b = 2
Combine like terms:
7 + 5b = 2
Now, let's isolate the term with b by subtracting 7 from both sides:
7 + 5b - 7 = 2 - 7
Simplifying:
5b = -5
Finally, solve for b by dividing both sides by 5:
(5b) / 5 = (-5) / 5
Simplifying:
b = -1
