Answer:

25.5 inches.

Step-by-step explanation:

To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

In this case, we have a right triangle with legs of length 19 inches and 17 inches. The length of the hypotenuse is the square root of the sum of the squares of the other two sides. We can calculate this as follows:

hypotenuse = sqrt(19^2 + 17^2)

hypotenuse = sqrt(361 + 289)

hypotenuse = sqrt(650)

hypotenuse = 25.495097568 inches

Rounding to the nearest tenth, the length of the hypotenuse is 25.5 inches.

Answer:

It is rounded to 3 sig figs already

Step-by-step explanation:

The answer for the first shape would be 24cm^2.

The answer for the second shape would be 20cm^2.

The answer for the third shape would be 30cm^2. "30".

What are Shapes?

A shape in geometry can be characterized as an object's form, outline, outer border, or outer surface.

The first shape seems to be scaling up. From 3cm to 12cm. So for this you need to multiply. Using the formula that I gave you last time.

3cm times ___ = 12cm. 4 fits in there,

therefore 6cm^2 times 4 = 24cm^2.

The answer for the first one would be 24cm^2. "24" in the blank.

The second shape seems to be scaling down. From 16cm to 8cm. So for this you need to divide.

16cm divided by ___ = 8cm. 2 fits in there,

therefore 40cm^2 divided 2 = 20cm^2.

The answer for the second one would be 20cm^2. "20" in the blank.

The third shape seems to be scaling up.

From 3cm to 4.5cm.

So for this you need to multiply. 3cm times ___ = 4.5cm.

Now since we're dealing with decimals, not whole numbers this time you can't really use guess and check as efficiently. So you do the opposite operation, which in this case the opposite of multiplication is division.

You take 3cm (the original shape's number) and divide it into 4.5cm. So 4.5cm divided by 3cm = 1.5. 1.5 fits in there,

therefore 20cm^2 times 1.5 = 30cm^2.

The answer for the third one would be 30cm^2. "30" in the blank.

Step-by-step explanation:

Total angle is 180°

a) The equation is 10p + 80 = 180 and p = 10.

b) The three angles are 90°, 37°, 53°.

What is an equation?

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Given that, the angles of the triangles are 53°, 2p + 17°, and 8p + 10°.

The sum of all angles of a triangle is  53° + 2p + 17° + 8p + 10° = 80 + 10p

The sum of all angles of a triangle is 180°.

Therefore,

80 + 10p = 180

Subtract 80 from both sides:

10p = 100

divide both sides by 10:

p = 10.

Putting p = 10 in 2p + 17°, and 8p + 10°:

2p + 17° = 20° + 17° = 37°

8p + 10° = 80° + 10° = 90°

The value of r is 45 and the value of s is 29

From the question, we are to solve the parallelogram for the missing variables.

The missing variables are r and s

Since opposite angles of a parallelogram are equal, we can write that

(r - 10)° = (3r - 100)°

Solve for r

r - 10 = 3r - 100

-10 + 100 = 3r - r

90 = 2r

r = 90/2

r = 45

Also,

We can write that

(5s)° = (4r - 35)°

Substitute the value of r and solve for s

5s = 4(45) - 35

5s = 180 - 35

5s = 145

Answer:

Therefore, the value of k is 1.

Step-by-step explanation:

Vertical angles are pairs of angles that are opposite each other and are formed by two intersecting lines. If one angle measures 160°, the other angle must measure 180° - 160° = 20°. Therefore, if the other angle measures (3k + 61)°, we can set up the equation 20 = 3k + 61. Solving for k, we get k = -41. However, since the value of k must be a positive integer, the only possible value of k is k = 1. Therefore, the value of k is 1.

The population of the state is 23.1 million

The population of the state will reach 28.3 million in 13.5 years

What is population ?

Any whole group that shares at least one trait is referred to be a population. People do not make up all populations. Populations can include, but are not limited to, individuals, animals, organizations, structures, buildings, cars, farms, objects, or occasions.

The population state is:

A = 23.1*e^(0.0153*t)

In millions.

Where t represents the number of years after 2000.

a) For the population at the year 2000, we need to evaluate the function at t = 0 (2000 is 0 years after 2000).

A(0) = 23.1*e^(0.0153*0) = 23.1

The population at year 2000 was 23.1 millions.

b) Now we want to solve:

A(t) = 28.3 = 23.1*e^(0.0153*t)

        28.3/23.1 = e^(0.0153*t)

        1.23 = e^(0.0153*t)

Now we can apply the natural logarithm to both sides:

ln(1.23) = ln( e^(0.0153*t) )

ln(1.23) = 0.0153*t

ln(1.23)/0.0153 = t = 13.5

So 13.5 years after 2000 the population will be 28.3 million.

When two quantities or variables are linearly related in mathematics, the term "proportional" is used. Both quantities increase by two times when one increases by two. Each variable decreases in proportion to the other when it falls to 1/100th of its previous value.

We must determine the ratio of the two quantities for each value supplied in order to determine if two quantities are proportionate. The proportionate link between them is evident if their proportions are equal. Their connection is not proportionate if all the ratios are out of balance.

The degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.

What is the quotient?

The number we obtain when we divide one number by another is the quotient. For example, in 8 ÷ 4 = 2; here, the result of the division is 2, so it is the quotient. 8 is the dividend and 4 is the divisor.

To find the quotient and remainder when dividing 8x³ +16x² + 12x+13 by 2x+2, we can use polynomial long division.

First, we divide the leading coefficient of the dividend (8x³) by the leading coefficient of the divisor (2x). This gives us a quotient of 4x². We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the first term of the remainder:

8x³ +16x² + 12x + 13

(2x+2)(4x²)

8x³ - 8x³ -8x² -8x² +12x+13

This leaves us with 12x+13 as the first term of the remainder.

Next, we bring down the next term of the dividend (16x²) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 8x. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the next term of the remainder:

12x+13

(2x+2)(8x)

12x+13 - 16x² - 16x

-4x² -4x

This leaves us with -4x² -4x as the next term of the remainder.

Finally, we bring down the last term of the dividend (12x) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 6. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the final term of the remainder:

-4x² -4x

(2x+2)(6)

-4x² -4x -12x -12

-16x² -16x

This leaves us with -16x² -16x as the final term of the remainder.

Hence, the degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.

We can write the result of the division as:

(8x³ + 16x² + 12x + 13) ÷ (2x+2) = (4x² + 8x + 6) + (-16x² -16x)/(2x+2)
