Answer:
26.55°C
Step-by-step explanation:
21.85 + 4.7
Average maximum daily temperature = 21.85°C
Average minimum temperature = - 4.7°C
The average daily maximum temperature is x°C higher than the average daily minimum temperature ;
x = (maximum temperature - minimum temperature)
x = (21.85 - (-4.7))°C
x = (21.85 + 4.7)°C
x = 26.55°C
Hence, The average daily maximum temperature is 26.55°C higher than the average daily minimum temperature
Jason claims he has finished reading 25% of his book. If his book has 200 pages, how many pages has he read?
Answer:
Jason has read 50 pages.
Step-by-step explanation:
25% of 200 = 50
Remember "of" means multiply so you multiply 25% to 200
25% x 200
Convert 25% into a decimal
0.25 x 200 = 50
So Jason has read 50 pages.
An industrial engineer must estimate the cost of building a storage tank. The tank requires 208 sq ft of material at $9.29 per square foot. It also requires 4.5 hours of labor at $26.40 per hour plus 1.6 hours of labor at $19.60 per hour. Find the total cost of the tank.
Answer:
The total cost of making the tank equals $2,082.48
Step-by-step explanation:
Giving the following information:
The tank requires 208 sq ft of material at $9.29 per square foot.
It also requires 4.5 hours of labor at $26.40 per hour plus 1.6 hours of labor at $19.60 per hour.
To calculate the total cost, we need to multiply the unitary variable cost by the total amounts:
Direct material= 9.29*208= $1,932.32
Direct labor= 4.5*26.4 + 1.6*19.6= $150.16
The total cost of making the tank equals $2,082.48

x-8y=-16
x+2y=3
-x+8y=16 (multiply both sides by-1)
10y=16
y=16/10
x+2(16/10)=3

Consider the graph of the polynomial function. Which of the following shows three binomial factors of the function?
Question 16 options:
A)
(x – 1)(x – 2)(x – 3)
B)
(x + 1)(x + 3)(x – 2)
C)
(x + 2)(x – 1)(x – 3)
D)
(x + 1)(x + 2)(x + 3)
Answer:
C
Step-by-step explanation:
the three binomial factors are (x+2)(x-1)(x-3)
Answer:
C
Step-by-step explanation:
Given a zero x = a then the corresponding factor is (x - a )
Here the zeros ( where the graph crosses the x- axis ) are at
x = - 2, x = 1 and x = 3
Thus the corresponding binomial factors are
(x - (- 2) ), (x - 1) and (x - 3), that is
(x + 2), (x - 1), (x - 3) → C

work out 4.52 times by 36
I just it into a calculator and got 162.72. Hope this helps you! Have a nice day and a nice rest of the holidays!
The product of 4.52 times by 36 is 162.72
Given,
4.52 times by 36
We need to find the product.
How do multiply decimal numbers?Example:
2.3 x 3.4 = 7.82
There are two numbers after the decimal point.
In 2.3 there is one number after the decimal point.
In 3.4 there is one number after the decimal point.
Now,
1 + 1 = 2 numbers
7.82 has two numbers after the decimal point.
We have,
4.52 times by 36
4.52 x 36 = 162.72
4.52 x 6 = 27.12
4.52 x 3 = 13.56
4.52
x 36
27.12
13.56
162.72
4.52 has two numbers after the decimal point.
162.72 has two numbers after the decimal point.
Thus the product of 4.52 times by 36 is 162.72

Answer:
I think its A
Step-by-step explanation:
Bernie’s estimated that 69% of 242 is 168 is her estimate reasonable
Answer:
Yes it is.
Step-by-step explanation:
Best way is to use percentages you know when estimating.
We know 50% is half.
50% of 242 is 121.
So it has to be more than 121.
10% of 242 is 24.2 so add that to 121 and you get 145.2
You are 60% so far. You just need 9% more.
Add another 10% which is 24.2 and you get 169.4, which is over but we used 10% instead of 9% so the estimate is reasonable and close.

The slope of the line represented by y = 5x is
Answer:
The slope of the line represented by y = 5x is 5
Step-by-step explanation:
The form of the linear function is y = m x + b, where
m is the slope of the line that represents the equationb is the y-intercept (the value of y at x = 0)To find the slope of a line from its equation compare the equation with the form of the linear function, then find the coefficient of x which is the slope of the line
∵ The equation of the line is y = 5x
→ Compare it with the form of the equation above
∵ The coefficient of x = 5
∴ m = 5
∴ The slope of the line represented by y = 5x is 5
Determine the slope-intersept form of the linear equation x/2 - y + 6 =0
Answer: slope =1/2 y intercept (0,6)
Step-by-step explanation: use the slope and y intercept form y=mx + b
A soap factory packs 7 bars of soap into each family pack. How many family packs can be made with 4,900 bars of soap?
Answer:
700 family packs
Step-by-step explanation:
In each family pack, there are 7 bars of soap. To find the number of family packs that can be made with 4900 bars of soap, we need to divide 4900 into groups of 7.
4900÷7
=700
Therefore, 700 family packs can be made with 4900 bars of soap.

Answer:
15. [tex] x = 8 [/tex]
16. m<V = 103°
17. [tex] x = 14 [/tex]
Step-by-step explanation:
15. The figure given is quadrilateral. Sum of interior angles of a quadrilateral = 360°
Therefore:
[tex] (10x + 6) + (13x - 2) + (8x - 1) + (180 - 71) = 360 [/tex]
Solve for x
[tex] 10x + 6 + 13x - 2 + 8x - 1 + 109 = 360 [/tex]
Add like terms
[tex] 31x + 112 = 360 [/tex]
Subtract 112 from each side
[tex] 31x = 248 [/tex]
Divide both sides by 31
[tex] x = 8 [/tex]
16. The polygon is a hexagon. Sum of interior angles of a hexagon = 720. Therefore:
[tex] 90 + (7x + 3) + 128 + (5x + 8) + 111 + (9x - 19) = 720 [/tex]
Solve for x
[tex] 90 + 7x + 3 + 128 + 5x + 8 + 111 + 9x - 19 = 720 [/tex]
Add like terms
[tex] 321 + 21x = 720 [/tex]
Subtract 321 from each side
[tex] 21x = 399 [/tex]
Divide both sides by 21
[tex] x = 19 [/tex]
m<V = 5x + 8
Plug in the value of x
m<V = 5(19) + 8 = 95 + 8
m<V = 103
17. The polygon is a regular pentagon. This means each of the angles measures 108°. The sum of the interior angles all together is 540.
Therefore:
[tex] (9x - 18) = 108 [/tex]
Solve for x
[tex] 9x - 18 = 108 [/tex]
Add 18 to both sides
[tex] 9x = 126 [/tex]
Divide both sides by 9
[tex] x = 14 [/tex]

Plz, mark brainiest! ^.^
Answer:
x = 4
Step-by-step explanation:
Use the distributive property to distribute the -3 amongst the 2x and the -3 in the parenthesis. Once distributed you should have -6x + 9 = -5x + 5. Next, you want to get all like terms on the same side, and to do that you must swap the +9 and the -5x. When you swap these, you must 'flip' the sign and change 9 to -9 and -5x to 5x. Now the equation should look like this: -6x + 5x = -9 + 5.
Now just solve. After solving, it should look like this: -1x = -4. Now to get rid of the negatives. Just divide each side by negative one and your answer is x = 4.
