The total cost for all chains produced in 10 minutes will be $303.14.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
An industrial factory makes 4 ³/₅ yards of chain every minute. Then the rate is given as,
Rate = 4 ³/₅
Rate = 4 + 3/5
Rate = 4 + 0.60
Rate = 4.60 yards per minute
The cost of each yard is $6.59. Then the cost per minute is given as,
⇒ $6.59 x 4.60
⇒ $30.314 per minute
Then the total cost for all chains produced in 10 minutes will be given as,
⇒ $30.314 x 10
⇒ $303.14

Step-by-step explanation:
-4x + 2y = 6
-4x + 2(x - 1) = 6
-4x + 2x - 2 = 6
-2x - 2 = 6
-2x - 2 + 2 = 6 + 2
-2x = 8
-2x/-2 = 8/-2
x = -4

Factor the following polynomial completely. -0.8x2 - 6.4x + 7.2
Answer:
-0.8(x + 9)(x - 1)
Step-by-step explanation:
Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2. Thus,
-0.8x2 - 6.4x + 7.2 = 0.8(-1x^2 - 8x + 9), or, equivalently,
= -0.8(x^2 + 8x - 9), which factors further as follows:
= -0.8(x + 9)(x - 1)
Angle A and angle B are complementary. Angle A has a
measure of (2X + 16). Angle B has a measure of 40. What is
the value of x?
Answer:
x = 17
Step-by-step explanation:
Angle A and angle B are complementary.
Therefore,
(2x + 16)° + 40° = 90°
(2x + 16)° = 90° - 40°
(2x + 16)° = 50°
2x + 16 = 50
2x = 50 - 16
2x = 34
x = 34/2
x = 17

What is the magnitude and direction of the PQ with tail and head points P(-6, 0) and Q(2, 4)?
8.9 units, 63.4° north of east
8.9 units, 26.6° north of east
13.4 units, 180° west
13.4 units, 0° east
Answer:
What is the magnitude and direction of the PQ−→− with tail and head points P(-6, 0) and Q(2, 4)? magnitude = √(64+16) = √80 = appr 8.9 , ruling out c.
hope this helps
The magnitude of PQ is 8.9 and PQ is making an angle of 26.57° so 8.9 units, 26.6° north of east will be the correct answer.
What is a vector?A vector is a quantity in which direction and magnitude both matters called a vector.
A vector joining by two points (x₁,y₁) and (x₂,y₂) will be (x₂-x₁)[tex]\hat{i}[/tex] + (y₂-y₁)[tex]\hat{j}[/tex]
The magnitude of this vector will be
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
The direction of this vector will be
[tex]\\tan^{-1}(\frac{y_2-y_1}{x_2-x_1)}[/tex]
Given P(-6,0) and Q(2,4) so vector joining by
[tex]\vec{PQ}[/tex] = [2-(-6)][tex]\vec{i}[/tex] + [4-0][tex]\vec{j}[/tex]
[tex]\vec{PQ}[/tex] = 8[tex]\vec{i}[/tex] + 4[tex]\vec{j}[/tex]
now, the magnitude [tex]\vec{PQ}[/tex] will be
⇒ [tex]\sqrt{(8^2+4^2)}[/tex]
⇒ 8.944
The direction of the vector [tex]\vec{PQ}[/tex] will be
⇒ [tex]\tan^{-1}(\frac{4}{8})[/tex]
⇒26.57°
So, the magnitude of PQ is around 8.944 and the direction is 26.57° from the positive x axis so it's north of the east.

Answer:
32
63
Step-by-step explanation:
m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.
m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.
Step-by-step explanation:
148 + x = 180
x = 180 - 148
x = 32
Find m<CAB basically means find the measure of the angle of A ( m<A )
m<B + m<A + x = 180
85 + m<A + 32 = 180
117 + m<A = 180
m<A = 180 - 117
m< A = 63, so m<CAB = 63
And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.
So m<BCA = 32

Find the value of (1/5)⁻² + (1/2)⁻³ + (1/4)⁻¹
Answer:
Answer = 37
Step-by-step explanation:
= (5)² + (2)³ + (4)¹
= 25 + 8 + 4
= 37 Answer
Answer: The answer is 37
Step-by-step explanation:
Step 1: Use Negative Power Rule: x^-a=1/x^a. So 1/(1/5)^2+(1/2)^-3+(1/4)^-1
Step 2: Use Division Distributive Property: (x/y)^a=x^a/y^a. So 1/1/5^2+(1/2)^-3+(1/4)^-1
Step 3: Simplify 5^2 to 25. So 1/1/25+(1/2)^-3+(1/4)^-1
Step 4: Use Negative Power Rule: x^-a=1/x^a. So 1/1/25+1/(1/2)^3+(1/4)^-1
Step 5: Use Division Distributive Property: (x/y)^a=x^a/y^a. So 1/1/25+1/1/2^3+(1/4)^-1
Step 6: Simplify 2^3 to 8. So 1/1/25+1/1/8+(1/4)^-1
Step 7: Use Negative Power Rule: x^-a=1/x^a. So 1/1/25+1/1/8+1/1/4
Step 8: Invert and multiply. 25+1/1/8+1/1/4
Step 9: Invert and multiply. 25+8+1/1/4
Step 10: Invert and multiply. 25+8+4
Step 11: Simplify 25+8 to 33. So 33+4
Step 12: Simplify. So the answer is 37
