Answer:

357

Step-by-step explanation:

hello :

note :    the n th term of an arithmetic sequence is :

An =A1+(n-1)d   ....a common difference is : d  and A1 the first term

in this exercice :   d = -3-(-7) =-7-(-11) = 4        A1 =  -11

when : n =93 you have the  93rd term  A93

so : A93 = -11 +(93-1)(4)

A93 = 357

Answer:

The rectangle is 7.9 meters by 2.9 meters.

Step-by-step explanation:

Let l be the length and w be the width

l = w + 5

A = 23 m²

Formula: A = lw

Solve for the dimensions

23 = (w+5)w

23 = w² + 5w

w² + 5w - 23 = 0

Use quadratic formula to find the possible value/s of w

\(w = \frac{-b+-\sqrt{b^2-4ac} }{2a}\\ w = \frac{-5+-\sqrt{5^2-4(1)(-23)} }{2(1)} \\w = \frac{-5+-\sqrt{25+92} }{2}\\ w = \frac{-5+-\sqrt{117} }{2} \\w = \frac{-5+-\sqrt{9(13)} }{2} \\w = \frac{-5+-3\sqrt{13} }{2}\\ w = \frac{-5+3\sqrt{13} }{2} = 2.9\\ w = \frac{-5-3\sqrt{13} }{2} = -7.9\)

Since we're dealing with dimensions, take the positive value which is 2.9.

w = 2.9 m

Substitute the value to l = w + 5

l = 2.9 + 5

l = 7.9 m

\(4.41=y^{2} +1.96\)

subtract 1.96 from both sides

\(2.45=y^{2}\)

\(y=1.5652\)

Now, to find x:-

\(x=y+y\)

\(= 1.5632+1.5652\)

Answer:

The correct option is (D) one of the non-fiction books on the bottom shelf and a second non-fiction book from the bottom shelf.

Step-by-step explanation:

What is probability?

Probability is the branch of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely it is that a claim is true.

To find which 2 books describe a pair of dependent events:

A pair of two dependent events are simply those in which the selection of the second item is contingent on the selection of the first item, causing the probability to change.

Because the sample size is lowered when the initial item is taken without replacement, choosing the exact same item reduces the chance.

Now, in regard to the question, this means that for two of the occurrences to be independent, they must be on the same shelf and of the same type of book, so that the second book cannot be selected until the first one is.

Option D, where both books are on the same shelf and are of the same type, is the only option that fulfills this requirement.

Therefore, the correct option is (D) one of the non-fiction books on the bottom shelf and a second non-fiction book from the bottom shelf.

Answer:

12 cm

Step-by-step explanation:

Well first we can cut the triangle in half and use the Pythagorean theorm

a^2+b^2=c^2

In this case we are going to be doing c^2-a^2=b^2

10^2-8^2=b^2

(10*10)-(8*8)=b^2

100-64=b^2

36=b^2

Now we just square root 36 (what number times itself is 36)

\(\sqrt{36}\)

b=6

Answer:  82 sq. units .

Step-by-step explanation:

Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.

Then we plot them on graph ( as provided in attachment)

Length = AB \(=\sqrt{(9+1)^2+(-1-7)^2}\) units  [By distance formula : \(\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)]

\(=\sqrt{(10)^2+(-8)^2}=\sqrt{100+64}=\sqrt{164}=2\sqrt{41}\) units

Width = BC = \(\sqrt{(-1+5)^2+(7-2)^2}\) units

\(=\sqrt{4^2+5^2}\\\\=\sqrt{16+25}\\\\=\sqrt{41}\)

Area = length x width

= \(2\sqrt{41}\times\sqrt{41}=2\times41= 82\text{ sq. units}\)

Answer and Step-by-step explanation:

To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:

7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8

So, Reuben used 5/8 yards more red fabric than yellow fabric.

The volume of the container is approximately 12.9516 cubic meters when rounded to the nearest hundredth.

To find the volume of the container, we need to multiply its length, width, and height. Let's convert the given measurements to meters to ensure consistent units.

The length of the container is 2.76 meters.

The width of the container is 23.5 decimeters, which is equal to 2.35 meters (since 1 decimeter = 0.1 meters).

The height of the container is 196 centimeters, which is equal to 1.96 meters (since 1 meter = 100 centimeters).

Now we can calculate the volume of the container:

Volume = Length × Width × Height

Volume = 2.76 meters × 2.35 meters × 1.96 meters

Volume ≈ 12.9516 cubic meters (rounded to four decimal places)

Therefore, the volume of the container is approximately 12.9516 cubic meters when rounded to the nearest hundredth.

Answer:

The temperature change is 23 because 18 - (-5)=23

Step-by-step explanation:

The speed of the car is 108 kilometers per hour and the distance covered in 5 hours is 540 kilometers.

Speed is simply referred to as distance traveled per unit time.

It is expressed as;

Speed = Distance ÷ time.

Given that the car is traveling at a rate of 30 meters per second.

First, convert the car's speed from meters per second to kilometers per hour using the conversion factor.

1 kilometer = 1000 meters

1 hour = 3600 seconds

Hence;

Speed = 30m/s = ( 30 × 3600/1000 )kmh

Speed = 108 kmh

Next, the distance covered in 5 hours will be:

Speed = Distance / time

Distance = speed × time

Distance = 108 kmh × 5 h

Distance = 540 km

Therefore, the disatnce covered is 540 kilometers.

Answer:

A is correct.  f(n) = -3n + 24

Step-by-step explanation:

We can see in the first two steps that two meals have been served, and six cups of pet food consumed.  In other words, six cups are consumed in two meals, therefore three cups are consumed in each meal.

If we look at the remaining numbers on the chart, we can see that this carries through.  This tells us that the correct answer must be either a or b, as "-3n" represents the consumption rate.  If it were (1/3)n, then only a third of a cup would be consumed per meal.

Finally, we can figure out which of those two equations is correct simply by plugging a value pair into them.  Starting with a:

f(1) = -3(1) + 24

= 24 - 3

= 21

correct.

To be certain, let's check with answer c:

f(1) = -3(1) + 64

= 64 - 3

= 61

incorrect.

So we can clearly say that the correct answer is "a".  You can plug the other values into it to test that too:

f(3) = -3(3) + 24

= 24 - 9

= 15

correct

So we definitely have the right answer.

Answer:

It will take 41.7 years for this investment to triple in value.

Step-by-step explanation:

Here is the formula for simple interest

\(A=P(1+rt)\)

Lets solve for \(t\).

Divide both sides by \(P\).

\(\frac{A}{P}=rt+1\)

Subtract 1 from both sides.

\(\frac{A}{P}-1=rt\)

Divide both sides by \(r\).

\(\frac{\frac{A}{P}-1}{r} =t\)

To write \(-1\) as a fraction with a common denominator, multiply by \(\frac{P}{P}\) .

\(\frac{\frac{A}{P}-1*\frac{P}{P}}{r} =t\)

\(\frac{\frac{A}{P}*\frac{-P}{P}}{r} =t\)

Combine the numerators over the common denominator.

\(\frac{\frac{A-P}{P} }{r} =t\)

Multiply the numerator by the reciprocal of the denominator.

\(t=\frac{A-P}{Pr}\)

We are given

\(P=3800\\r=0.048\)

We need to find what amount is triple his money.

\(3800*3=11400\)

\(A=11400\)

Substitute our numbers into the equation for \(t\).

\(t=\frac{11400-3800}{3800*0.048}\)

Factor 3800 out of 11400.

\(t=\frac{3800*3-3800}{3800*0.048}\)

Factor 3800 out of −3800.

\(t=\frac{3800*3-3800*-1}{3800*0.048}\)

Factor 3800 out of \(3800*3-3800*-1\).

\(t=\frac{3800*(3-1)}{3800*0.048}\)

Cancel the common factor of 3800.

\(t=\frac{3-1}{0.048}\)

Simplify.

\(t=\frac{2}{0.048}\)

\(t=41.666\)

Answer:

100°

Step-by-step explanation:

tThe sum of all arc measures that make up that circle is 360 degrees.

QS + RQ + RS = 360

QS = 360 - 120 - 140 = 100

An arc angle is the degree measurement of that angle inside the circle, opposite the arc

m∠R = arc QS = 100°

Answer:

∠ R = 50°

Step-by-step explanation:

the inscribed angle R is half the measure of its intercepted arc QS

the sum of the arcs on a circle is 360° , that is

RQ + QS + SR = 360°

120° + QS + 140° = 360°

QS + 260° = 360° ( subtract 260° from both sides )

QS = 100°

Then

∠ R = \(\frac{1}{2}\) × 100° = 50°
