Answer:The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.
Step-by-step explanation:⇒ 6 x 10⁻⁶ and 2 x 10⁻⁸⇒ 600 x 10⁻⁸ and 2 x 10⁻⁸The number 600 x 10⁻⁸ times greater than the number 2 x 10⁻⁸ will be ⇒ 600 x 10⁻⁸ / 2 x 10⁻⁸⇒ 300
Final answer:
The circumference of Saturn is not greater than that of Earth; Earth's circumference is greater. Saturn's circumference at 40,100 km is approximately 0.11 times that of Earth. Also, 0.037854921 rounded to the nearest hundredth is 0.04, and 6 x 10⁻⁶ is larger than 2 x 10⁻⁸.
Explanation:
To answer how many times greater the circumference of Saturn is than the circumference of Earth, we need to compare the two given circumferences. The circumference of Earth is 365,882 km, and the circumference of Saturn is given as 4.01 x 10⁴ km.
First, we convert Saturn's circumference to a standard numerical form: 4.01 x 10⁴ is 40,100 km. Now, we can divide the circumference of Saturn by the circumference of Earth: 40,100 km / 365,882 km which roughly equals 0.11. This means that Saturn's circumference is about 0.11 times the circumference of Earth, which indicates that Earth's circumference is actually greater, not Saturn's.
For the second part, estimating 0.037854921 to the nearest hundredth would result in 0.04 because the third digit after the decimal is 7, which rounds the second digit up to 4.
Comparing the numbers 6 x 10⁻⁶ and 2 x 10⁻⁸, 6 x 10⁻⁶ is larger because it is only 10⁻⁶ compared to 2 x 10⁻⁸ which is much smaller being 10⁻⁸.

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails and each large box has 400 nails. The contractor bought 3 times as many large boxes as small boxes, which altogether had 2700 nails. Determine the number of small boxes purchased and the number of large boxes purchased.
The contractor bought 2 small boxes and 6 large boxes of nails. This was determined by setting up and solving a system of equations based on the given conditions.
Explanation:To solve the problem of determining the number of small and large boxes of nails purchased by the contractor, we can set up a system of equations based on the information given:
Each small box contains 150 nails.Each large box contains 400 nails.The contractor bought 3 times as many large boxes as small boxes.Altogether, the nails totaled 2700.Let's denote the number of small boxes as S, and the number of large boxes as L. The equations then are:
L = 3S (3 times as many large boxes as small boxes)150S + 400L = 2700 (total number of nails)Substituting the value of L from equation (1) into equation (2):
150S + 400(3S) = 2700
Solving for S:
150S + 1200S = 2700
1350S = 2700
S = 2
Then, substituting S = 2 into the first equation to find L:
L = 3(2) = 6
Therefore, the contractor bought 2 small boxes and 6 large boxes of nails.
The contractor bought 2 small boxes and 6 large boxes, totaling 2700 nails, with each small box containing 150 nails.
Let's denote:
- x as the number of small boxes purchased.
- y as the number of large boxes purchased.
We're given the following information:
1. Each small box contains 150 nails.
2. Each large box contains 400 nails.
3. The total number of nails purchased is 2700.
4. The contractor bought 3 times as many large boxes as small boxes, so y = 3x.
We can set up two equations to represent the given information:
1. Total number of nails equation:
150x + 400y = 2700
2. Relationship between the number of small and large boxes:
y = 3x
Now, let's substitute the value of y from the second equation into the first equation:
150x + 400(3x) = 2700
150x + 1200x = 2700
1350x = 2700
Now, let's solve for x:
[tex]\[ x = \frac{2700}{1350} \][/tex]
x = 2
So, the number of small boxes purchased [tex](\( x \))[/tex] is 2.
Now, let's find the number of large boxes [tex](\( y \))[/tex]:
y = 3x
y = 3(2)
y = 6
So, the number of large boxes purchased [tex](\( y \))[/tex] is 6.
To summarize:
- The contractor purchased 2 small boxes.
- The contractor purchased 6 large boxes.

what is the ratio for the surface areas of the cones shown below, given that they are similar and that the ratio of their radii and altitudes is 5:4?
Answer:
25:16 is the surface area of the cones.
Step-by-step explanation:
Given: The ratio of their radii and altitudes is 5:4.
Area of similar figures are proportional to the squares of their corresponding sides and this ratio is called scale factor.
Let z be the scale factor
∴z= [tex]\frac{5}{4}[/tex]
Now, let x be the surface area of the larger cone
and let y be the surface are of smaller cone.
∴ [tex]z^{2} = \frac{x}{y}[/tex]
next substituting the value of z ,
⇒[tex](\frac{5}{4} )^{2} =\frac{x}{y}[/tex]
∴ [tex]\frac{x}{y} = \frac{25}{16}[/tex]
The ratio for the surface area of cones is 25:16

[tex]\frac{(x+4)^2}{25}+\frac{(y+3)^2}{9}=1[/tex]
Step-by-step explanation:
Given:
Center of the ellipse is, [tex](h,k)=(-4,-3)[/tex]
Minor axis length is, [tex]2b=6[/tex]
A vertex of the ellipse is at (1, -3)
Now, distance between the center and the vertex is half of the length of the major axis.
Using distance formula for (-4, -3) and (1, -3), we get:
[tex]a=\sqrt{(1+4)^2+(-3+3)^2}=5[/tex]
Therefore, the value of half of major axis is, [tex]a=5[/tex]. Also,
[tex]2b=6\\b=\frac{6}{2}=3[/tex]
Now, equation of an ellipse with center [tex](h,k)[/tex] is given as:
[tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]
Plug in [tex]h=-4,k=-3,a=5,b=3[/tex] and determine the equation.
[tex]\frac{(x-(-4))^2}{5^2}+\frac{(y-(-3))^2}{3^2}=1\\\\\frac{(x+4)^2}{25}+\frac{(y+3)^2}{9}=1[/tex]
Therefore, the equation of the ellipse is:
[tex]\frac{(x+4)^2}{25}+\frac{(y+3)^2}{9}=1[/tex]
Assume that in October of a particular year about 215 billion text messages were sent or received in the US, and the prediction is that in the next month it will be a 13% increase. About how many will be sent or received in November of the same year? Rounded to the nearest tenth of a billion.
Answer:
There will be [tex]243[/tex] billion messages sent or received in November.
Step-by-step explanation:
Given.
Number of text messages sent or received [tex]=215[/tex] billion.
Increment on the very next month [tex]=13\%=\frac{13}{100}=0.13[/tex]
Lets find what is [tex]13\%\ of\ 215[/tex]
⇒[tex]13\%\ of\ 215[/tex]
⇒[tex]0.13\times 215=27.95[/tex]
So we will add this value to our previous months data.
Now
Number of text messages sent in the month of November [tex]=(27.5+215)=242.95[/tex] billion.
Rounding to the nearest tenth the answer will be [tex]243[/tex] billion.
So [tex]243[/tex] billion text messages were sent or received in November.

(–4, 0) and (–3, 0)

The graph of the quadratic function f(x) = 0.5x² + x - 9 crosses the negative x-axis between the ordered pairs (-7,0) and (-6,0), and between (-2,0) and (-1,0).
Explanation:The graph of the quadratic function f(x) = 0.5x² + x - 9 crosses the negative x-axis at those x-values that make the function equal to zero. To find these, we solve for x in the equation 0.5x² + x - 9 = 0 using the quadratic formula x = -b ± √(b² - 4ac) / 2a.
Here, a = 0.5, b = 1 and c = -9. Substituting these into the formula gives x = -1 ± √(1 + 36) / 1 = -1 ± √(37) / 1. The two possible solutions are approximately -7.06 and +5.06. Therefore, the ranges of x-values crossing the negative x-axis are between the ordered pairs (-7,0) and (-6,0), as well as between (-2,0) and (-1,0).

The function f(x) = one-halfx2 + x - 9 intersects the negative x-axis between the ordered pairs (-4, 0) and (-3, 0) and also between (-3, 0) and (-2, 0) when solved using the quadratic formula.
Explanation:The question concerned is a quadratic function, specifically, it wants to know where f(x) = one-halfx2 + x – 9 intersects with the negative x-axis. The x-axis is the line where y = 0, so we need to solve the equation 0.5x² + x - 9 = 0 to locate the roots. By applying the quadratic formula, x = [-b ± sqrt(b² - 4ac)] / (2a), we substitute our coefficients into the equation to get: x = [-1 ± sqrt((1)² - 4*0.5*(-9))] / (2*0.5). This will lead to two solutions, x = -2 and x = -3. Hence, the function f(x) = one-halfx2 + x – 9 intersects the negative x-axis between the ordered pairs (-4, 0) and (-3, 0) and also between (-3, 0) and (-2, 0).

Step-by-step explanation:
Given
(bx + a)(ax + b) = (ax² + b)b ← distribute parenthesis on both sides
abx² + a²x + b²x + ab = abx² + b² ( subtract abx² from both sides )
a²x + b²x + ab = b² ( subtract ab from both sides )
a²x + b²x = b² - ab ← factor out x from each term on the left side
x(a² + b²) = b² - ab ← divide both sides by (a² + b²)
x = [tex]\frac{b^2-ab}{a^2+b^2}[/tex]
Answer:
x = -b/a
Step-by-step explanation:
(bx + a)(ax + b) = (ax^2 + b)(b) needs to be muliplied out as a first step to solving for x:
abx^2 + b^2 + a^2x + ab = abx^2 + b^2
Notice that abx^2 shows up on both sides of this equation, so we can cancel it out:
b^2 + a^2x + ab = b^2
Also, b^2 shows up on both sides, so we can also cancel the b^2 terms:
a^2x + ab = 0
Dividing both sides by a, we get ax + b = 0
and so ax = -b,
which means that x = -b/a
Given O below, if XY and YZ are congruent, what is the measure of chord XY
Answer:
B. 10.2
Step-by-step explanation:
Answer : The value of chord XY is, 10.2 units
Step-by-step explanation :
As we are given that, XY and YZ are congruent.
XY and YZ are congruent by SSA.
The ΔXOY and ΔZOY are congruent triangles.
Side OX = Side OZ (side)
Side OY = Side OY (common side)
∠XOY = ∠ZOY (angle)
That means, in this two sides and one angle of a triangle are equal to another triangle then the triangles are congruent.
So, Side XY = Side YZ
As we are given :
Chord YZ = 10.2
So, Chord YZ = Chord XY = 10.2
Hence, the value of chord XY is, 10.2 units

Patsy has cheerleading practice every fourth day. She wants to be in the school play, but they have practice every sixth day. If both start on September 5th, what would be the next date she has to choose between cheerleading and play practice? Show your work and explain.
Answer:
September 17th will be the first date that she has to choose between cheerleading and play practice.
Step-by-step explanation:
Least Common Multiple for 4 and 6 is 12 that is LCM(4, 6) = 12
12 days after September 5th is September 17th
Patsy would need to choose between cheerleading and play practice on September 29th, as this is the next date when both practices fall on the same day, calculated by finding the least common multiple of the practice schedules.
Explanation:To determine when Patsy has to choose between cheerleading and play practice, we need to find the least common multiple (LCM) of the two practice schedules, since she has cheerleading every fourth day and play practice every sixth day.
First, list the multiples of both 4 and 6 until we find a common one:
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, ...Multiples of 6: 6, 12, 18, 24, 30, ...The lowest common multiple of 4 and 6 is 12, but since our sequence started on September 5th and 12 is not a multiple of both 4 and 6, we need to keep going. Continuing our list, 24 is the next common multiple but still not satisfying both conditions. At 24 days, the cycle would repeat itself, and Patsy would again have both practices on the same day.
If these practices both start on September 5th, to find the next date she has both practices, we add 24 days to September 5th. Because September has 30 days, adding 24 days to September 5th results in September 29th. Hence, Patsy would need to choose between cheerleading and play practice on September 29th.

To find the cost of the slippers after the 30% discount, multiply the original price by 30% and subtract the discount from the original price. The cost of the slippers after the discount is $10.50.
Explanation:To find the cost of the slippers after the 30% discount, first calculate the amount of the discount by multiplying the original price by 30% (or 0.30).
Discount = $15 × 0.30 = $4.50
Next, subtract the discount from the original price to find the sale price:
Sale Price = $15 - $4.50 = $10.50
Therefore, the cost of the slippers after the discount is $10.50.
A textbook store sold a combined total 402 of psychology and math textbooks in a week. The number of psychology textbooks sold was two times the number of math textbooks sold. How many textbooks of each type were sold?
Answer:
The number of textbooks of each type were sold is 134 math and 268 psychology books.
Step-by-step explanation:
Given:
Total number of math and psychology textbooks sold in a week is 402.
Now, let the number of math textbooks sold be [tex]x[/tex].
And, the number of psychology textbooks be [tex]2x[/tex].
According to question:
[tex]x+2x=402[/tex]
[tex]3x=402[/tex]
Dividing both sides by 3 we get:
[tex]x=134[/tex]
So, total number of math textbooks were 134 .
And, total number of psychology textbooks were [tex]2x=2\times 134[/tex]
[tex]=268[/tex].
Therefore, the number of textbooks of each type were sold is 134 math and 268 psychology books.

Answer:
Two equivalent fractions with whole numbers may be 180/150, or 6/5The height of the tree is 39.6 feet.Explanation:
The diagram provides the proportion of the heights to the shadows:
[tex]\frac{x}{33}=\frac{1.8}{1.5}[/tex]From that you are asked (i) to simplify the fraction of the right side to one with whole numbers.
You can do that in two steps by multiplying both numerator and denominator by 10:
[tex]\frac{1.8\times 10}{1.5\times 10}=\frac{180}{150}[/tex]You can simplify that fraction if you divide by the greatest common factor of 180 and 150, which is 30:
[tex]\frac{180/30}{150/30}=\frac{6}{5}[/tex]The second part (ii) asks to find the height of the tree, that is x. To solve for x you can multiply both sides by the denominator of the fraction on the left and then simplify:
[tex]\frac{x}{33}=\frac{6}{5}\\ \\ x=\frac{6\times 33}{5}\\ \\ x=\frac{198}{5}=39.6[/tex]
Thus, the height of the three is 39.6 feet.
