The surface area of the square pyramid when the base is 12 and slant is 10 cm is 384cm².

It should be noted that the total surface area will be:

= b² + 2bs

where b = base length

s = slant height

Surface area = (12)2 + 2(12)(10)

Surface area = 144 + 240

Surface area = 384cm².

In conclusion, the surface area of the square pyramid when the base is 12 and slant is 10 cm is 384cm².

The total cost of using the old car is $4,679.29

The total cost of using the newer car is $ 8,896.25.

The total cost of using the old car: (cost of maintenance x number of years) + ( miles driven to work / miles per gallon x cost per gallon x number of weeks in a year x number of years)

 ($870 x 3) + (110 / 17 x $2.05 x 52 x 3)

$2,610 + 2069.29 = $4,679.29

The total cost of using the newer car : purchase price + (cost of maintenance per month x number of months in year x number of years) + (miles driven to work in a week / number of miles per gallon x weeks in  year x number of year)

$8000 + ($10 x 12 x 3) + (110 / 32 x 52 x 3)

The algebraic expression that represents the total cost would be: A. 1.25r.

Given that the number of donuts Rick buys for his family is represented by letter "r", and we also know that:

cost of each donut = $1.25.

Using an algebraic expression, we can create a mathematical expression that shows the total cost for Rick to by a given number of donuts for his family.

Thus:

1 donut = 1.25

r donuts would cost: 1.25 × r = 1.25r.

Therefore, the algebraic expression that represents the total cost would be: A. 1.25r.

The amount generated by the invested amount of $500 which is compounded quarterly will be $610.

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

[tex]\rm A = P \left (1 + \dfrac{r}{n} \right ) ^{nt}[/tex]

Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.

If $500 had been invested at an annualized rate of 8%, the money would have after 2.5 years. For the quarterly, the value of n will be 4. Then the amount will be

[tex]\rm A = 500 \left (1 + \dfrac{0.08}{4} \right)^{4 \times 2.5}[/tex]

Simplify the equation, then the amount is given as,

A = 500 (1 + 0.02)¹⁰

A = 500 (1.02)¹⁰

A = 500 x 1.22

A = $610

The amount generated by the invested amount of $500 which is compounded quarterly will be $610.

Answer:

120

Step-by-step explanation:

consider
1st angle= a
2nd angle = b
3rd angle = c

now,
b=5a ............. equation 1
c = a+12 ........ equation 2

as we know in a triangle, sum of all angle is 180.

so
a+b+c = 180
=> a +5a + (a+12 ) = 180
=> 7a = 180-12 =168
=> a = 168/7 = 24

so a= 24
b = 5(24) = 120
c = a+12 = 24+12 =36

so b = largest = 120

The height of parallelogram is 6

In geometry, parallelogram is a shape which is a type of quadrilateral. A parallelogram has 2 pair of sides which are parallel. Thus, we can say that a parallelogram is a quadrilateral of 2 pair of parallel sides. The opposite sides of parallelogram are of equal side.

Parallelogram is a convex polygon, which is a 2-dimentional geometric shape.

The number of cockroaches in Chandler in the year 2025 will be 3237500 or 3.23 million approx

Approx number of cockroaches in the year 2020 in Chandler = 3500000 or 3.5 million

Percentage decrease in cockroaches every 12 years = 18%

Percentage decrease in cockroaches every year = 18/12 = 1.5%

So, in 5 years the percentage decrease in cockroaches will be = Percentage decrease every year*No. of years = 1.5*5 = 7.5%

The number of cockroaches in 2025 will be: 3500000 - 7.5% of 3500000

= 3500000 - 7.5/100*3500000

= 3500000 - 262500

= 3237500

Work Shown:

x = smallest side

y = medium side

z = largest side

x = y-79

z = y+377

x+y+z = perimeter

x+y+z = 3064

(y-79) + (y) + (y+377) = 3064

3y + 298 = 3064

3y = 3064-298

3y = 2766

y = 2766/3

y = 922

x = y-79

x = 922-79

x = 843

z = y+377

z = 922+377

z = 1299

------------------

Summary:

x = 843, y = 922, z = 1299

Check:

x+y+z = 843+922+1299 = 3064

which matches the given perimeter, so the answer is confirmed.

The 47th term in the given arithmetic sequence is 34.

Given,

The arithmetic sequence = 310, 304, 298,......

First term of the sequence, t₁ = 310

Common difference of the sequence, d = t₂ - t₁ = 304 - 310 = -6

nth term of an arithmetic sequence, tₙ = t₁ + ( n - 1) d

We have to find the 47th term of the arithmetic sequence.

That is, n = 47

So,

t₄₇ = 310 + (47 - 1) -6

t₄₇ = 310 + (46 x (-6) )

t₄₇ = 310 - 276

t₄₇ = 34

Therefore, the 47th term in the given arithmetic sequence is 34.

The point of intersection of the given two lines y = 4x - 1 and y = -2x + 5  is (1, 3).

According to the given question.

We have two equations

y = 4x - 1 ..(i)

and

y = -2x + 5 ..(ii)

As we know that, the point at which two lines intersect is called point of intersection.

Therefore, the point of intersection for the two lines y = 4x - 1 and y = -2x + 5  is given by

Subtracting equation ii from i

y - y = 4x - 1 + 2x -5

⇒ 0 = 6x - 6

⇒ 6x = 6

⇒ x = 1

Substitute the value of x in (i).

y = 4 - 1 = 3

Hence, the point of intersection of the given two lines y = 4x - 1 and y = -2x + 5  is (1, 3).

Inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. Inequality issues can be expressed as either questions or theorems, and both can be resolved using techniques that are similar to those used to resolve equations.
