It would be 603.2 square inches.

Answer: 35 cm^2

Step-by-step explanation:

The area of a triangle is found by base * height divided by 2.

Base = 10

Height = 7

So, plug those values into the equation and you get:

10*7/2 = 35

Essentially, the formula for the area of a triangle is just dividing the formula for the area of a rectangle by 2, because two triangles make up one rectangle.

Answer:

Step-by-step explanation:

We are given with a triangle whose Height is 7 cm and base is 10 cm.

We have to calculate the Area of triangle.

As we know that area of triangle is calculated by,

Area = ½ × base × height

Putting the required values we get,

Area = 1/2 × 7 × 10

Area = 7 × 5

Area = 35 cm².

Hence, The area of the triangle is 35 cm².

Step-by-step explanation:

Carla is 1.3 miles away from the home.

Given that, Carla leaves home and walks 40° easy to the north for 1.5 miles, then turns and continues due west for 2 miles.

The formula for the cosine rule is c=√(a²+b²-2ab cosC)

Here, c=√(1.5²+2²-2×1.5×2 cos40°)

c=√(2.25+4-6×0.7660)

c=√1.654

c=1.28

c=1.3 miles

Therefore, Carla is 1.3 miles away from the home.

Answer:

9 tins of cat food feed her 2 cats for 18 days

Step-by-step explanation:

Sally has 2 cats

food eaten by 1 cat each day =

food eaten by 2 cat each day=  tins

sally buys 9 tins of cat food

then

tins  required in = 1 day

1 tin required in

i.e  1 tin required in  2 days

9 tin  required  for = 9×2 = 18 days

hence ,  9 tins of cat food feed her 2 cats for 18 days

The volume of a sphere whose diameter is 18 centimeters is 972π cubic centimeters. If its diameter were reduced by half, its volume would be 1/8 of its original volume. So, correct options are D for both blanks.

The diameter of a sphere is 18 cm, so its radius is half of the diameter, which is 9 cm. The formula for the volume of a sphere is (4/3)πr³, where r is the radius of the sphere.

Using this formula, we can calculate the volume of the sphere as follows:

V = (4/3)π(9³)

V = (4/3)π(729)

V = 972π cubic cm

Therefore, the volume of the sphere is 972π cubic cm.

Now, if the diameter of the sphere is reduced by half, the new diameter would be 9 cm, which means the new radius would be half of 9 cm, which is 4.5 cm. Using the same formula for the volume of a sphere, we can calculate the new volume of the sphere as follows:

V' = (4/3)π(4.5³)

V' = (4/3)π(91.125)

V' = 121.5π cubic cm

To find the ratio of the new volume to the original volume, we can divide the new volume by the original volume:

V'/V = (121.5π) / (972π) = 1/8

Therefore, the answer to the first part of the question is option (d) 972π cubic cm, and the answer to the second part of the question is option (d) 1/8.

Step-by-step explanation:

Regarding resolving the given issue, we have Total equation  cost = 225 + 80*4 = 545 This is less than the $970 she will have in total ($410 + $560).

A mathematical equation is a formula that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign places a space between the variables 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The symbol and the single variable are frequently the same. as in, 2x - 4 equals 2, for instance.

A) Let's start by figuring out the DJ's total cost. Kat will pay $80 per hour, so if she hires him for X hours, she will spend 80*X dollars. When the venue fee is added, the party's whole cost is:

Cost overall = 225 + 80*X

With the money she has saved and the money she will make, Kat can afford to pay the party's entire cost, which is the sum of the DJ and venue costs. In order to express the potential number of hours Kat will be able to afford to pay the DJ for the party, we may construct the following compound inequality:

225 + 80*X ≤ 410 + 560

80*X ≤ 795

X ≤ 9.9375

The compound inequality is as a result:

0 ≤ X ≤ 9.9375

B) Based on Part A, we know that Kat has the money to hire the DJ for 0 to 9.9375 hours. Kat could be able to pay the DJ for four hours, considering that:

Total cost = 225 + 80*4 = 545

This is less than the $970 she will have in total ($410 + $560).

The maturity value at the end of 6 years is $37,098 (option a).

To calculate the maturity value of Ariana's loan, we can use the formula for compound interest. The formula for compound interest is:

A = P(1 + r/n)ⁿˣ

Where:

A = the maturity value

P = the principal amount borrowed

r = the annual interest rate (as a decimal)

n = the number of times interest is compounded per year

x = the length of time the loan is taken out for

In this case, Ariana borrowed $31,500 for 6 years at an interest rate of 2.9%. We know that interest is compounded annually, so n = 1. Substituting these values into the formula, we get:

A = 31,500(1 + 0.029/1)¹ˣ⁶

A = 31,500(1.029)⁶

A = 31,500(1.1945)

A = 37,098

Therefore the answer $37,098, which is answer choice (a).

The measure of angle x is 114.6°

Here, the central angle of sector of circle is represented by x.

We know that the formula for the area of sector.

A = θ/360 × πr²

where  θ is the central angle

and r is the radius of the circle

Here, the area of the sector is equal to the area of the square.

Using the formula for the area of square,

A = side²

A = r²

Since area of sector = area of square,

x/360 × πr² = r²

x = 360/π

Given data ,

Let the triangle be represented as ΔMNP

Now , the measure of side MP = 46

The measure of side MN = 34

And , the measure of ∠MNP = 78°

Now , from the law of sines , we get
