To find the measures of complementary angles A and B with a known difference of 20 degrees, we set up a system of equations and solved them to find that angle A measures 55 degrees and angle B measures 35 degrees.

The problem involves finding the measures of two complementary angles, angle A and angle B, with a known difference in their measures. By definition, complementary angles are two angles whose sum is 90 degrees. Given the difference of 20 degrees between the angles, we can set up a system of equations to solve for their measures.

Let's denote the measure of angle A as a and angle B as b. Therefore, we have the two equations based on the problem statement:

a + b = 90 (because they are complementary)

a - b = 20 (the difference in their measures)

To find the values of a and b, we can add the two equations:

a + b = 90
a - b = 20

By adding them together, we get:

2a = 110

Dividing both sides by 2, we find a:

a = 55

To find b, we substitute a back into one of the original equations:

55 + b = 90

Subtracting 55 from both sides gives us b:

b = 35

Therefore, angle A measures 55 degrees and angle B measures 35 degrees.

Answer:

The weight of baby at the end of 8 month is 18.125 lb.

Step-by-step explanation:

Given information:

The weight of baby at birth = 7.25 lb

At the end of 8 months, the baby weighed [tex]2\frac{1}{2}[/tex] times its birth weight.

We need to find the weight of baby at the end of 8 month.

[tex]2\frac{1}{2}=\frac{4+1}{2}=\frac{5}{2}[/tex]

The weight of baby at the end of 8 month is 5/2 times of its initial weight.

[tex]\text{Total weight}=7.25\times \frac{5}{2}[/tex]

[tex]\text{Total weight}=18.125[/tex]

Therefore the weight of baby at the end of 8 month is 18.125 lb.

This problem is about a arithmetic sequence, which is obtained by summing a term which is called "difference". In this case, we need to find the tenth term of the arithmetic sequence, because that's the term assigned for October. The formula of an arithmetic sequence is

[tex]a_{n}=a_{1}+(n-1)d[/tex]

Where:

[tex]n=10\\a_{1}=16\\d=15[/tex]

Replacing values, we have

[tex]a_{10}=16+(10-1)15=151[/tex]

Therefore, on October you will have $151 if you deposit $15 more each month, beginning with $16.

Answer:

135m²

Step-by-step explanation:

Perimeter = 2(l + w)

l = w + 6

Substituting for l, gives;

2(w+6+w)

48 = 2w + 12 +2w

48 = 4w + 12

48 - 12 = 4w

36 = 4w

w = 9

Since w = 9, then l = w +6

l = 9 + 6

l = 15

Area = l * w

Area = 15 * 9

Area = 135m²

The smallest positive integer with exactly 14 positive divisors is 24. The number is found by considering its prime factorization and adding 1 to each exponent, then multiplying the results together. Another prime factor raised to the power of 5 can be included to have exactly 14 divisors.

The smallest positive integer with exactly 14 positive divisors is 24.

To find this, we need to consider the prime factorization of the number. Let's express 24 as a product of prime factors: 24 = 2^3 * 3^1.

The number of divisors is found by adding 1 to each exponent in the prime factorization and multiplying them together: (3+1)(1+1) = 4 * 2 = 8. However, we need exactly 14 divisors, so we can multiply 24 by another prime factor raised to the power of 5: 24 * 5^4 = 24 * 625 = 15,000.

The smallest positive integer with exactly 14 positive divisors is 192. We derived this by using the prime factorization method and finding suitable combinations to get exactly 14 divisors.

To find the smallest positive integer with exactly 14 positive divisors, we need to understand the number of divisors formula. For an integer n = p1e* p2e² * ... * p^ke^k, the number of divisors is given by (e1 + 1)(e² + 1) ... (e^k + 1).

To have exactly 14 divisors, we need (e1 + 1)(e² + 1) ... (e^k + 1) = 14. The factorizations of 14 are 14 = 14 * 1, 7 * 2, or 2 * 7. Let's use the smallest primes to minimize our number:

14 = 14 * 1: This means n = p113. Using the smallest prime number, we have n = 213 = 8192, which is too large.

14 = 7 * 2: This means n = p16 * p21. Using the smallest primes, we get n = 26 * 3 = 64 * 3 = 192.

14 = 2 * 7: This means n = p11 * p26. Using the smallest primes, we get n = 2 * 36 = 2 * 729 = 1458.

Comparing these solutions, the smallest positive integer is n = 192, which has exactly 14 positive divisors.

Quadrilateral DEFG is not a rhombus because the four sides do not all have the same length.

The coordinates of the vertices of quadrilateral DEFG are D(-2, 5), E(2, 4), F(0, 0), and G(-4, 1). To determine if DEFG is a rhombus, we need to observe the properties of a rhombus. A rhombus has opposite sides that are parallel and all four sides have the same length. Using the distance formula, we calculate the lengths of the four sides of DEFG:

As we can see, the lengths of DEFG's sides are not all the same. Therefore, DEFG is not a rhombus.

I believe that the correct measurement in feet is 1.4 x 10^5 feet. You forgot to include the ^5.

So since that is the measurement of 1 marathon, therefore half a marathon would simply be also half of that, that is:

0.7 x 10^5 feet

or

7 x 10^4 feet

Final answer:

Half a marathon is 69,168 feet in length. To calculate the runner's time for a full marathon at an average speed of 9.5 mi/h, divide the distance (26.2 miles) by the speed, resulting in approximately 2.76 hours or about 2 hours and 45 minutes.

Explanation:

To find the length of half a marathon in feet, we first need to know the length of a full marathon in feet then divide that by 2. Since one marathon is approximately 26.2 miles, we first need to convert miles to feet. There are 5,280 feet in one mile. So, for a full marathon:

26.2 miles × 5,280 feet/mile = 138,336 feet for a full marathon.

Therefore, half a marathon would be:

138,336 feet ÷ 2 = 69,168 feet for half a marathon.

Next, let's look at the question about the marathon runner's time. If a runner averages 9.5 mi/h over a full marathon of 26.2 miles, we can calculate the time taken to run this distance. Time is distance divided by speed, so:

26.2 miles ÷ 9.5 mi/h = approximately 2.76 hours,

which can be converted to minutes: 2.76 hours × 60 minutes/hour = approximately 165.6 minutes or about 2 hours and 45 minutes.

The graph of f(x) after transforming into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 units up is g(x) = 2x + 2.

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and shape.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

The graph of f(x) = 6x

Vertical compression = 1/3.

Translation = 2 units up.

If there is a vertical compression of 1/3 on the graph f(x).

The graph of f(x) = 6x transformed as g(x) = 1/3 x 6x = 2x

Now,

If the graph g(x) 2x has a translation of 2 units up we get,

g(x) = 2x + 2

g(x) = 2(x + 1)

Thus,

The graph of f(x) after transforming into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 units up is g(x) = 2x + 2.

The question is about calculating the probability of selecting a blue block from a bag containing a mix of different colored blocks. When finding the probability of an event, the formula to use is the number of ways the event can happen divided by the total number of outcomes. In the case of the blue block, if a bag has 4 red, 2 blue, and 4 green blocks, there are

To calculate the probability of choosing a blue block, you divide the number of blue blocks by the total number of blocks:

Probability(Blue) = Number of Blue Blocks / Total Number of Blocks

The actual height of the building is 54 meters.

The actual height of the building is calculated by multiplying the scale drawing height by the scale factor.

Given that the scale is 1:600, this means that 1 centimeter on the drawing represents 600 centimeters in reality.

Therefore, to find the actual height of the building, one would multiply the height of the building on the scale drawing (9 cm) by the scale factor (600).

Using the scale, the actual height H of the building can be determined as follows:

[tex]\[ H = \text{scale drawing height} \times \text{scale factor} \] \[ H = 9 \, \text{cm} \times 600 \] \[ H = 5400 \, \text{cm} \][/tex]

To convert centimeters to meters, since there are 100 centimeters in a meter, we divide by 100:

[tex]\[ H = \frac{5400 \, \text{cm}}{100} \] \[ H = 54 \, \text{m} \][/tex]

Thus, the actual height of the building is 54 meters.
