Find the value of x
I give you 10 points if you help

Answer:

67.5

Step-by-step explanation:

area of a triangle (1/2 l×b)

1/2 ×9×15× x=135x

divide any side by 2

x=4.5×15=67.5

x=67.5

The value of x is 67.5.

We have given that,

A triangle has side lengths of 9 centimeters and 15 centimeters.

The third side has a length of x centimeters

The area of a triangle is  (1/2 l×b)

l is length and b is a breadth.

Therefore we use the given value in the formula so

1/2 ×9×15× x=135x

divide any side by 2

x=4.5×15=67.5

x=67.5.

Therefore the third side of the triangle is 67.5.

So the inequality is

67.5≤15≤9.

Answer:

x = 61

Step-by-step explanation:

These 2 angles are supplementary which means they add up to 180:

The sum of the first eight terms in this series is 97,750.

We have,

We notice that each term in the series is obtained by multiplying the previous term by 5.

Therefore, this is a geometric series with a common ratio of 5.

We can use the formula for the sum of the first n terms of a geometric series:

[tex]S_n = a(1 - r^n)/(1 - r)[/tex]

where a is the first term, r is the common ratio, and n is the number of terms.

In this case,

a = 2, r = 5, and n = 4 (since we have four terms).

Substituting these values into the formula gives:

[tex]S_4 = 2(1 - 5^4)/(1 - 5)[/tex]

= 2 (-624)/(-4)

= 156

The sum of the first four terms is 156.

To find the sum of the first eight terms, we need to find the sum of the first four terms and then multiply by the common ratio raised to the power of 4:

[tex]S_8 = S_4 \times 5^4[/tex]

= 156 x 625

= 97,500

Adding the last term (250) to this sum gives:

= [tex]S_8[/tex] + 250

= 97,500 + 250

= 97,750

Therefore,

The sum of the first eight terms in this series is 97,750.

Answer:

Volume of Cuboid = 72 cubic feet

Step-by-step explanation:

Using 1 cubic foot as standard

Given:

Length of given cuboid = 6 feet

Width of given cuboid = 3 foot

Height of given cuboid = 4 foot

Find:

Volume of Cuboid

Computation:

Volume of Cuboid = Length of cuboid x Width of cuboid x Height of cuboid

Volume of Cuboid = (6)(3)(4)

Volume of Cuboid = 72 cubic feet

Hence, 120 flowers were sold in total on that day as the Roses made up 35% of the total number of flowers.

In mathematics, the unitary approach entails determining the value of a single unit and then using that value to determine the value of a certain number of units. It is frequently applied to issues concerning rates and proportions as well as issues relating to ratios and proportions. The unitary method, for instance, would result in a cost of $5 for 5 apples if the price of 1 apple is $2. To calculate the overall cost using the unitary method, we would multiply the $2 worth of one apple by the quantity we wish to purchase. Therefore $5 would be spent on 5 apples, or $2 each.

given

Assume that "x" represents the total quantity of flowers sold on that particular day.

Roses made up 35% of the total number of flowers, which means that:

0.35x = 42

By dividing both sides by 0.35, we can determine the value of "x":

x = 120

Hence, 120 flowers were sold in total on that day as the Roses made up 35% of the total number of flowers.

Answer:

A) The algebraic expression

= 12x + 7 = 91

B) He drives 7 miles per day

Step-by-step explanation:

For 11 days straight, Mike drove the same distance every day going to and coming from work.

Step 1

We are told : Mike drives 91 miles in total in those 12 days,

On the 12th day, he drove an extra 7 miles.

Hence:

91 miles - 7 extra miles

= 84 miles

Step 2

The number of miles he drives per day:

84 miles/12

= 7 miles per day

Step 3

The expression we can use to find the distance he travels each day going to and from work is written as:

Let the number of miles he travels be day = x

12x + 7 = 91 miles

12x + 7 = 91

12x = 91 - 7

12x = 84

x = 84/12

x = 7 miles per day

Amount left= 4,327.9 - 1,800

Step-by-step explanation:

Giving the following information:

Initial deposit (PV)= $3,500

Interest rate (i)= 11.2%

Number of periods (n)= 2 years

Withdrawal= $1,800

First, we need to calculate the future value of the investment at the end of 2 years:

FV= PV*(1 + i)^n

FV= 3,500*(1.112^2)

FV= $4,327.9

Now, after the withdrawal:
