A sum of _________ can be factored according to the pattern (a + b)(a2 - ab + b2).
Answers
Solution:
we are given with [tex] (a + b)(a^2 - ab + b^2) [/tex]
we have been asked to find the representation of the given factor as a Sum.
As we know that

Because
[tex] (a + b)(a^2 - ab + b^2)=a(a^2 - ab + b^2)+b(a^2 - ab + b^2)\\

2. To simplify this one, we are going to use the rule for negative exponents twice, the product rule: [tex](a^{n} )(a^{m} )=a^{n+m} [/tex], and the power rule [tex](a^{n}) ^{m} =a^{(n)(m)} [/tex], so:
[tex](w^{-2} j ^{-4} ) ^{-3} (j^{7} j ^{3} )=( \frac{1}{w ^{-2}j ^{-4} } )^{3} (j ^{7+3} )[/tex]

b. [tex]5.38[/tex] x [tex]10^{2} =538[/tex]
Expressions with exponents can be simplified using rules of exponents, and numbers can be converted into scientific notation by recognizing how to move the decimal point and denote magnitude with the power of ten.
To simplify expressions with exponents and convert numbers into scientific notation, we apply the rules of exponents and understand the format of scientific notation.

A car has a 12-volt battery. The engine has a resistance of 0.22 ohms. How many amps will be drawn from the battery when the key is turned? I (to the nearest hundredth)
Answers
Answer:
54.54 amps.Step-by-step explanation:
Amps refers to the electrical current.
We have to find the electrical current when the car has a 12-volt battery and the engine has a resistance of 0.22 ohms.
The relation between these magnitudes is
[tex]V=I\times R[/tex]
Where [tex]V[/tex] is the voltage, [tex]I[/tex] is the electrical current and [tex]R[/tex] the resistance.
We know that [tex]V=12; R=0.22[/tex]. Replacing these values in the formula and solving for [tex]I[/tex]
[tex]V=I\times R\\\frac{V}{R}=I\\ I=\frac{12}{0.22}\\ I\approx 54.54 amp[/tex]
Therefore, the answer is around 54.54 amps.
The current drawn from the battery when the key is turned is approximately 54.55 amps.
To determine the current drawn from the battery, we can use Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R):
[tex]\[ I = \frac{V}{R} \][/tex]
Given that the voltage (V) of the battery is 12 volts and the resistance (R) of the engine is 0.22 ohms, we can plug these values into the equation:
[tex]\[ I = \frac{12 \text{ volts}}{0.22 \text{ ohms}} \][/tex]
[tex]\[ I = \frac{12}{0.22} \][/tex]
[tex]\[ I \approx 54.5454 \][/tex]
Rounding to the nearest hundredth, we get:
[tex]\[ I \approx 54.55 \text{ amps} \][/tex]

The perimeters of two similar quadrilaterals are 48 cm and 60 cm, respectively. If the area of the smaller quadrilateral is 96 cm2, find the area of the larger quadrilateral.
Answers
The area of the larger quadrilateral is found by using the scale factor derived from the ratio of the perimeters of the similar quadrilaterals, which comes out to 150 cm².
The question involves finding the area of a larger quadrilateral given the perimeters of two similar quadrilaterals and the area of the smaller one. In similar figures, the ratio of their areas is the square of the ratio of their corresponding linear dimensions, such as side lengths or perimeters in this case. Since the perimeters are 48 cm and 60 cm, the ratio of the perimeters (also the scale factor) is 48/60, or 4/5. Consequently, the ratio of the areas is the square of the scale factor, which is (4/5)² or 16/25. Knowing the area of the smaller quadrilateral is 96 cm², we find the area of the larger quadrilateral by dividing the area of the smaller by the scale factor squared and then multiplying by the larger scale factor squared. This gives us (96 / (16/25)) cm² = (96 * 25/16) cm² = 150 cm².
So, the area of the larger quadrilateral is 150 cm².

Catie is trying to determine the height that a ladder reaches as it leans against a wall. She walks under the ladder and touches her forehead to it as shown. If her feet are 16 inches from the ladder's base, the ladder's base is 4.5 feet from the bottom of the wall, and Catie is 5 feet 6 inches tall, then come up with an estimate for how high the ladder reaches up the wall to the nearest tenth of a foot. Watch your units on this problem and show all work
Answers
Catie creates a similar triangle with the ladder so we can create a proportion to solve for the height.
[tex] \frac{baseto feet}{base to wall} = \frac{catie height}{wall height} [/tex]
Convert all values to feet . 16in = 1.33 ft . 5ft 6 in = 5.5 ft
Insert values into proportions
[tex] \frac{1.33}{4.5} = \frac{5.5}{x} [/tex]
Cross multiply to get
24.75=1.33x
divide both sides by 1.33
x=18.56ft
To find the height the ladder reaches up the wall, set up a proportion using similar triangles and Catie's height as the ladder's height. The estimate for the ladder's height up the wall is 6.8 feet.
Given information:
Catie is 5 feet 6 inches tall.Her feet are 16 inches from the ladder's base.The ladder's base is 4.5 feet from the bottom of the wall.To find the height the ladder reaches up the wall, we can set up a proportion using similar triangles. Catie's height can be considered as the ladder's height, and the distance on the wall can be related to the ladder's base and height.
Using the information provided and performing the calculations, the estimate for the height the ladder reaches up the wall would be approximately **6.8 feet** to the nearest tenth of a foot.

Will give brainliest please answer quickly
Answers
The first equation would be
3B=2R+18.
The second equation would be
5B=6R-2.
To get the coefficients of R the same we will multiply the first equation by 3:
3(3B=2R+18)
which gives us
9B=6R+54
Now our system is
9B=6R+54
5B=6R-2
We will subtract the bottom equation to eliminate R:
9B=6R+54
-(5B=6R-2)
which gives us
4B=56
Divide both sides by 4:
4B/4=56/4
B=14
Substitute this into our first original equation:
3(14)=2R+18
42=2R+18
Subtract 18 from both sides:
42-18=2R+18-18
24=2R
Divide both sides by 2:
24/2=2R/2
12=R
Final answer:
By creating and solving a system of equations based on the given information, we find that there are 10 blue marbles and 8 red marbles.
Explanation:
To solve this problem, we set up two equations based on the information given:
3 times the number of blue marbles (3B) exceeds 2 times the number of red marbles (2R) by 18: 3B - 2R = 18.
5 times the number of blue marbles (5B) is 2 less than 6 times the number of red marbles (6R): 5B = 6R - 2.
Now, we can solve these equations using substitution or elimination. Using substitution, solve the second equation for B:
B = ⅜(6R - 2)
Then substitute this expression for B in the first equation:
3(⅜(6R - 2)) - 2R = 18
Solve for R:
R = 8
Now substitute R back into the equation for B:
B = ⅜(6(8) - 2) = 10
Thus, there are 10 blue marbles and 8 red marbles.

By cutting away identical squares from each corner of a rectangular piece of cardboard and folding up the resulting flaps, an open box may be made. if the cardboard is 17 in. long and 12 in. wide, find the dimensions of the box that will yield the maximum volume. (round your answers to two decimal places.)
Answers
The initial measurements of the box are:
Length: 17
Width: 12
Height: 0
Right now, the volume is zero. However, if we let the height equal 0 (the amount of the cut out), we can write the following equation for the volume.
Volume = (17 - 2x)(12 - 2x)x
If you graph this, you will find a maximum value of 211.05, keeping in mind that the cut out must be less than 6.

Answers
Final answer:
The ratio of 1.02 can be converted to a fraction by multiplying by 100 to get 102/100 and then simplifying to its simplest form, which is 51/50.
Explanation:
To write the ratio 1.02 as a fraction in its simplest form, we first recognize that 1.02 is the same as 1.02/1. If we want to express this as a fraction, we must remove the decimal point by multiplying both the numerator and the denominator by 100 (because there are two digits after the decimal point). This gives us 102/100. We can then simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2. Therefore, the simplified fraction is 51/50.
