Answer:
The product of the first and last digits is 40.
Step-by-step explanation:
Multiple of 4 rule:
The last two digits must form a number that is divisible by 4.
Multiple of 11 rule:
We find the alternate sum of the digits, and it must be divisible by 11.
A SECRET CODE has 5 digits. The middle 3 digits are 926
So the code is
x926y
Divisible by 4:
This means that the 6y must be divisible by 4, which means that the possible values of y are 0, 4, 8.
Value of x when y = 0:
x9260
x - 9 + 2 - 6 + 0 = x - 13
It will be divisible by 11 when x - 13 = 22, that is, x = 9. However, the digit 9 is already used, which means that y = 0 is not a possible option.
Value of x when y = 4:
x9264
x - 9 + 2 - 6 + 4 = x - 9
It will be divisible by 11 when x - 9 = 0, that is, x = 9, which is not possible, as we saw above. Or
x - 9 = 11
x = 2
The digit 2 is also possible, so y cannot be 4.
Value of x when y = 8:
x9268
x - 9 + 2 - 6 + 8 = x - 5
x - 5 = 0 -> x = 5
So, the number is:
59268
What is the product of the first and last digits?
5*8 = 40
The product of the first and last digits is 40.

Kristin's Bikes rents bikes for $11 plus $2 per hour. Willie paid $23 to rent a bike. For how many hours did he rent the bike?
Define the variable, write an equation, and solve the equation.
Answer:
6
Step-by-step explanation:
Let x = number of hours.
Let y = cost.
The fixed cost is $11.
The cost per hour is $2.
For x hours, the cost per hour is 2x.
y = 2x + 11
23 = 2x + 11
12 = 2x
x = 6

Equation Form: x = 7/5, y = 7/5Answer:
2y = -3x + 7
Step-by-step explanation:
(3, -1) and (-1, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5+1)/(-1-3)
m=6/(-4)
m= -3/2
Slope-intercept:
y - y1 = m(x - x1)
y + 1 = -3/2(x - 3)
y + 1 = -3/2x + 9/2
y = -3/2x + 7/2
Standard form:
y = -3/2x + 7/2
3x + 2y = 7
2y = -3x + 7

The highest elevation in Delaware is 106 feet higher than the highest elevation in Florida. Louisiana's highest elevation is 190 feet higher than Florida's highest elevation. If you climbed from sea level to the highest points in Delaware, Florida, and Louisiana, you would only climb 1331 feet. How high is the highest elevation in each of the three states?
Answer:
Florida = 345 feets
Delaware = 451 feets
Louisiana = 535 feets
Step-by-step explanation:
Given that:
Let :
Highest elevation in Florida, = x
Highest elevation in Delaware = x + 106
Highest elevation in Louisiana = x + 190
Sum of highest elevation in the 3 states = 1331 feets
Hence,
x + x + 106 + x + 190 = 1331
3x + 296 = 1331
3x = 1331 - 296
3x = 1035 feets
x = 1035 / 3
x = 345 feets
Hence,
Highest elevation in Florida, = x = 345
Highest elevation in Delaware = 345 + 106 = 451
Highest elevation in Louisiana = 345 + 190 = 535

his earnings into his account. They both worked the same number of hours and now have the same
amount of money in their accounts. Which of the following equations could be used to determine
the amount hours they worked?
A 15x + 590 = 20x + 545
B 20x + 590 = 15x + 545

a metal box that is in shape of cuboid has the following dimensions. the length is 9 inches, width is 2 inches and height is 1. 5 inches. find the total cost of silver coating the entire box if the cost of coating is $2.50 per Sq. inches
Given:
Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.
The cost of silver coating is $2.50 per sq. inches.
To find:
The total cost of silver coating for the box.
Solution:
The total surface area of a cuboid is
[tex]A=2(lb+bh+hl)[/tex]
Where, l is length, b is breadth and h is height.
Putting [tex]l=9,b=2,h=1.5[/tex], we get
[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]
[tex]A=2(18+3+13.5)[/tex]
[tex]A=2(34.5)[/tex]
[tex]A=69[/tex]
So, the total surface area of the box is 69 square inches.
Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is
[tex]Cost=69\times 2.50[/tex]
[tex]Cost=172.50[/tex]
Therefore, the cost of silver coating for the box is $172.50.

Answer:
a) x <= 15 b) x > 16.5 c) x < 34.5 d) x =/= 23
Step-by-step explanation:
For a), there is a shaded region for where 15 is, and the number line is going towards the left, so x will be less than but also equal to 15
For b), there is not a shaded region for where 16.5 is, but the number line is going towards the right, so x will be greater than 16.5
For c), there is not a shaded region for where 34.5 is, but the number line is going towards the left, so x will be less than 34.5
For d), there is not a shaded region for where 23 is, but the number line is going everywhere else so it is x =/= 23(x does not equal to 23)
Solve using elimination.
-4x + 7y = -1
6x - 7y = 5
Answer:
(4,-1)
Step-by-step explanation:
x is 4 y is -1
Answer:
(2,1)
Step-by-step explanation:
Let's solve your system by elimination.
6x−7y = 5;−4x+7y=−1
6x−7y=5
−4x+7y=−1
Add these equations to eliminate y:
2x = 4
Then solve2x = 4for x:
2x = 4
(Divide both sides by 2)
x = 2
Now let's plug x in to solve for y.
6x - 7y = 5
6(2) - 7y = 5
12 - 7y = 5
subtract 12 on both sides.
-7y = -7
divide both sides by -1
y = 1
A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid is What is the height of the pyramid?
Answer:
9.48
Step-by-step explanation:
Complete question
A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid 90.1. What is the height of the pyramid?
To get the height of the pyramid, we will use pythagoras theorem.
slant height l is the hypotenuse
length of the base is the adjacent
height of the pyramid is the opposite
According to the theorem;
l² = h² + b²
90.1² = h² + 89.6²
8,118.01 = h²+8,028.16
h²= 8,118.01 - 8,028.16
h² = 89.85
h =√89.85
h = 9.48
Hence the height of the pyramid will be 9.48
Note that the value of the slant height was assumed to solve the problem.
Simplify the expression
-2.3(-4p+1)-0.7
9.2p−3 Is the answer

Donna is putting down tile on her outdoor deck. The shape of her deck is shown below. Each unit on the coordinate plane represents 5 feet. Find the area of flooring needed in square feet.
Round your final answer to the nearest tenth.
The given area presented on the coordinate plane has dimensions
given by the lengths of the line joining the vertices.
Response:
The area of the flooring needed is 13.5 ft²How can the area of the shape be calculated?The given figure can be taken as a composite figure of wo triangles and
a trapezium.
Area of the triangle at the top, A₁ = 0.5 × 4.5 × 1 = 2.25
Area of the trapezoid, A₂ = 0.5 × (6 + 4.5) × 1 = 5.25
Area of the bottom triangle, A₃ = 0.5 × 2 × 6 = 6
Therefore;
Area of the figure, A = A₁ + A₂ + A₃
Which gives;
A = 2.25 + 5.25 + 6 = 13.5
Area of the flooring needed, A = 13.5 ft²

Find the value of x.
Answer:
[tex]\boxed {\boxed {\sf A. \ 18}}[/tex]
Step-by-step explanation:
The two angles are inside a right angle. The small box signifies a right angle/ 90° angle.
Therefore, the sum of the angle measures must equal 90. We can set up an equation.
[tex]56+(x+16)=90[/tex]
Combine the like terms on the right side. The 2 constants: 56 and 16 can be added.
[tex](56+16)+x=90\\[/tex]
[tex]72+x=90[/tex]
Since we are solving for x, we must isolate the variable. 72 and x are being added. The inverse of addition is subtraction, so subtract 72 from both sides.
[tex]72-72+x=90-72[/tex]
[tex]x=18[/tex]
x is equal to 18 and choice A is correct.
