in july 2008, the u.s. population was approximately 302,000,000. approximately how many americans were there in july 2009 if the estimated 2008 growth rate was 0.88%?
Answers
Approximately 304,657,600 Americans were there in July 2009 based on the estimated 2008 growth rate of 0.88%.
To find the approximate US population in July 2009, we need to apply the growth rate of 0.88% to the initial population in July 2008.
Convert the growth rate from percentage to decimal:
0.88% = 0.0088
Calculate the number of people added to the population in 2008: 302,000,000 * 0.0088 = 2,657,600
Add this number to the initial population to find the population in July 2009:
302,000,000 + 2,657,600 = 304,657,600.
For similar question on growth rate.

the lengths of the sides of a triangle are in the extended ratio 7:8:9 the perimeter of the triangle is 96cm. what are the lengths of the sides?
Answers
Answer:
28 cm, 32cm , 36cm
Step-by-step explanation:
Given:
The lengths of the sides of a triangle are in the ratio 7:8:9Perimeter of triangle is 96cmTo Find:
The lengths of the sides of triangle?Solution:
Let:
1st side = 7x 2nd side = 8x 3rd side = 9xAs, we know that,
★ Perimeter of Triangle = Sum of all sides ★
➝ 7x + 8x + 9x = 96cm
➝ 24x = 96cm
➮ x = 96/24
➮ x = 4
So, length of the sides are:
7x = 7 × 4 ➝ 28cm
8x = 8 × 4 ➝ 32cm
9x = 9 × 4 ➝ 36cm
Given :
The length of the sides of the triangle are in the ratio 7:8:9 .The Perimeter of the Triangle is 96 cm.To Find :
The length of the sides of the triangle.Solution :
Let us assume the sides be 7x cm, 8x cm and 9x cm.
We know,
\(\qquad{ \bold{ \pmb{Sum \: of \: all \: sides \: of \: the \: triangle = Perimeter_{(Triangle)}}}}
\)
So, Substituting the values :
\(\qquad { \dashrightarrow{ \sf{7x + 8x + 9x = 96}}}\)
\(\qquad { \dashrightarrow{ \sf{24x= 96}}}\)
\(\qquad { \dashrightarrow{ \sf{ \dfrac{24x}{24} = \dfrac{96}{24} }}}\)
\(\qquad { \dashrightarrow{ \bf{ x = 4 }}}\)
Therefore,
The length of the sides of the triangle are :
\(\qquad { \dashrightarrow{ \sf{ 7x \: cm= 7 \times 4 \: cm = \bf \: 28 \: cm }}}\)
\(\qquad { \dashrightarrow{ \sf{ 8x \: cm= 8 \times 4 \: cm = \bf \: 32 \: cm }}}\)

Follow Me❤In the coordinate plane, the point a (3,-4) is translated to the point a' (-2, "-3)." under the same translation, the points b (1, 0) and c (-1,-1) are translated to b' and c' , respectively. what are the coordinates for b' and c'?
Answers
The coordinates of point b' are (-4, 1) and the coordinates of point c' are (-6, 0).
To obtain the coordinates of points b' and c' after the same translation as point a', we need to apply the same translation vector to points b and c.
The translation vector can be found by calculating the differences between the x-coordinates and the y-coordinates of points a' and a.
Translation Vector = (x-coordinate of a' - x-coordinate of a, y-coordinate of a' - y-coordinate of a)
= (-2 - 3, -3 - (-4))
= (-5, 1)
Now, we can obtain the coordinates of points b' and c' by adding the translation vector to the respective coordinates of points b and c.
For point b':
Coordinates of b' = (x-coordinate of b + x-coordinate of translation vector, y-coordinate of b + y-coordinate of translation vector)
= (1 + (-5), 0 + 1)
= (-4, 1)
Therefore, the coordinates of point b' are (-4, 1).
For point c':
Coordinates of c' = (x-coordinate of c + x-coordinate of translation vector, y-coordinate of c + y-coordinate of translation vector)
= (-1 + (-5), -1 + 1)
= (-6, 0)
Therefore, the coordinates of point c' are (-6, 0).

\(x - 4z = 12x - y - 6z = 42x + 3y - 2z = 8\)
Answers
The value of x = 16, y = 172 and z = 2.
x - 4z = 12x - y - 6z = 42x + 3y - 2z = 8
let x - 4z = 8 be equation (1), 12x - y - 6z = 8 be equation (2) and 42x + 3y - 2z = 8 be equation (3)
x - 4z = 8
x = 8 + 4z
12x - y - 6z = 8
12(8 + 4z) -y - 6z =8
96 + 48z - y - 6z = 8
42z - y = -88
y = 42z + 88
42x + 3y - 2z = 8
42(8+4z) + 3(42z + 88) - 2z = 8
336 + 168z + 126z + 264 - 2z = 8
168z + 126z + 2z = 336+264 - 8
296z= 592
z = 2
substituting the value of z
x = 8 + 4z

Step-by-step explanation:
Since segment xz is perpendicular to segment wy, angles wzx and xzy are both right angles and congruent. The proportion ________ shows the corresponding sides are proportional, so the triangles are similar by the sas similarity postulate.
Answers
The proportion 16 over 12 equals 12 over 9 shows the corresponding sides are proportional, so the triangles are similar by the SAS similarity postulate.
What is SAS similarity theorem?
According to the Side-Angle-Side Postulate (SAS) postulate, triangles are congruent if two sides of one triangle and the angle that connects them are congruent with two sides and the included angle of a second triangle. According to the SAS criteria for triangle similarity, two sides of one triangle are comparable to two sides of another triangle if their included angles are congruent.
The proof showing that ΔWXZ ~ ΔXYZ is presented as follows;
Segment XZ is perpendicular to segment WY
∠WZX and ∠XZY are right angles by definition of XZ perpendicular to WY
∠WZX in ΔWXZ = ∠XZY in ΔXYZ = 90° (definition)
Given that two sides of ΔWXZ are proportional to two sides of ΔXYZ, and
that the included angles between the two sides, ∠WZX and ∠XZY are
congruent, the two triangles, ΔWXZ and ΔXYZ are similar by Side-Angle-
Side, SAS, similarity postulate.
The option that best completes the proof is therefore;
which is; 16 over 12 equals 12 over 9
The SAS similarity test determines whether two triangles are similar if the ratio of the lengths of two sides of one triangle equals the ratio of the lengths of two sides of another triangle, and the included angles are equal.

Petrol has a density of: 740 kg/m³ A container holds 12 litres of petrol. One litre is equal to 0.001 m³. What is the mass of the petrol?
Answers
The mass of the petrol is 8.88 kg.
Given, Petrol has a density of 740 kg/m³.
A container holds 12 litres of petrol.
One litre is equal to 0.001 m³.
As, Density = Mass/Volume
1 litre = 0.001 m³
12 litres = 0.012 m³
Now, using the formula, we get
740 = mass/0.012
mass = 740×0.012
mass = 8.88 kg
Hence, the mass of the petrol is 8.88 kg.

By using the approximation of 62,500 inches to the mile, you can simplify and expedite various calculations involving distances and conversions between inches and miles, providing a convenient tool for numerical analysis and problem-solving
The approximation of 62,500 inches to the mile is commonly used in various calculations, especially in scenarios where conversions between inches and miles are involved. This approximation simplifies the conversion process and allows for easier calculations.
For example, if you need to convert a distance from miles to inches, you can simply multiply the number of miles by 62,500 to obtain the equivalent distance in inches. Conversely, if you have a measurement in inches and want to convert it to miles, you divide the number of inches by 62,500 to get the distance in miles.
Additionally, this approximation can be useful in other applications, such as determining the number of inches in a given number of miles, or calculating the length of a specific distance in miles based on its measurement in inches.

Assume that the distribution of birth weights is Normal with a standard deviation of 0.3 ounce. a. Find the birth weight of cats at the 70th percentile. b. Find the birth weight of cats at the 30th percentile
Answers
a. The birth weight of cats at the 70th percentile is approximately 3.156 ounces. b. The birth weight of cats at the 30th percentile is approximately 2.844 ounces.
To answer your question, we will use the given information about the normal distribution of domestic cat birth weights with a mean of 3 ounces and a standard deviation of 0.3 ounces.
a) To find the birth weight of cats at the 70th percentile, we first need to find the z-score associated with the 70th percentile. You can look up this value using a standard normal distribution table or a calculator with a built-in function for percentiles. For the 70th percentile, the z-score is approximately 0.52.
Next, we use the z-score formula to find the corresponding birth weight:
x = mean + (z-score * standard deviation)
x = 3 + (0.52 * 0.3)
x ≈ 3.156 ounces
b) Similarly, to find the birth weight of cats at the 30th percentile, we find the z-score associated with the 30th percentile, which is approximately -0.52.
Using the z-score formula again:
x = mean + (z-score * standard deviation)
x = 3 + (-0.52 * 0.3)
x ≈ 2.844 ounces
