D. one hundred and twenty two hundredths
Answer:
A. 31/100
Step-by-step explanation:
Change 3/10 to hundreds:
3/10 × 10/10 = 30/100
The denominator (the bottom number) must be 100.
61 - 30 is 31.

Follow the rules to create two number sequences that go to the fifth term each. Rule 1: Multiply by 2 starting at 10. Rule 2: Subtract 4 starting from 24. What is the first term that appears in both sequences? (2 points) Group of answer choices 10 14 20 26
Answer:
Step-by-step explanation:
Created Sequences
S1: 10 20 40 80 150
s2:24 20
The first term that appears in both sequences is the second term. Both of them equal 20.
I don't think you have to go any further once you get the first term.
Method
S1: Multiply by 2 starting with 10.
10*2 = 20
20*2 = 40
S2: Start at 24 and subtract 4
24 - 4 = 20
20 - 4 = 16
16 - 4 = 12
he figure shows a parallelogram inside a rectangle outline:
A parallelogram is shown within a rectangle. The length of the rectangle is 3 over 5 foot, and the width of the rectangle is 2 over 5 foot. The two equal bases of the triangles outside the parallelogram are labeled 1 over 5 foot.
What is the area of the parallelogram?
1 over 25 square foot
11 over 25 square foot
3 over 25 square foot
4 over 25 square foot
Answer:
4/25 foot²
Step-by-step explanation:
Refer to attachment*
Consider the attachment first for a better understanding, now after considering the attachment you will gotta know that, the height of the parallelogram is just same as the width of the rectangle i.e (2/5) foot and but for the base of the parallelogram we can subtract the base of one triangle from the length of the rectangle, so it will give us (3/5) - (1/25) = (2/5), so now we have breadth as well as height of the parallelogram, so now, as area of a parallelogram is given by it's height times it's base, so we will be having
[tex]{:\implies \quad \sf Area_{(Parallelogram)}=\dfrac{2}{5}\times \dfrac25}[/tex]
[tex]{:\implies \quad \boxed{\bf{Area_{(Parallelogram)}=\dfrac{4}{25}\:\: sq.\:\:foot}}}[/tex]
Hence, Option D) is correct
Well, we have another method for it, we can subtract the area of both the triangles from the area of rectangle, and now,as their base of the triangle is (1/5) foot and height is same as the width of rectangle i.e (2/5) foots, so its area will be (1/2) times base times height, but as here are two triangles, so multiplying the area of one triangle by 2 will vanish 2, so now we just have
[tex]{:\implies \quad \sf Area_{(Parallelogram)}=\bigg(\dfrac{2}{5}\times \dfrac{3}{5}\bigg)-\bigg(\dfrac{1}{5}\times \dfrac{2}{5}\bigg)}[/tex]
[tex]{:\implies \quad \sf Area_{(Parallelogram)}=\dfrac{6}{25}-\dfrac{2}{25}}[/tex]
[tex]{:\implies \quad \boxed{\bf{Area_{(Parallelogram)}=\dfrac{4}{25}\:\: sq.\:\:foot}}}[/tex]
This also, proves that the correct answer is D)

Which expression is equivalent to 6f+f?
Answer:
A
Step-by-step explanation:
This is because 6f+f is just 7f.
f f f f f f+f = fffffff
Soooo, ONLY A gives us 7f when added together again.
f+5f+f=7f.
f+ f f f f f +f = fffffff
Answer:
[tex]f + 5f + f[/tex] is equivalent to [tex]6f + f[/tex].
Step-by-step explanation:
You can plug in any numbers to both expressions and they will always have the same outcome.
For example, let's plug in 2.
[tex]6f + f\\6(2) + 2\\12 + 2 = 14[/tex]
[tex]f + 5f + f\\2 + 5(2) + 2\\2+10+2 = 14[/tex]

An arithmetic sequence has first term a = 5 and common difference d = 2. How many terms of this sequence must be added to get 1440?
To find how many terms of this sequence must be added to get 1440, we must know the arithmetic sequence equation to find any term in the sequence:
⇒ [tex]a_{n}=a_{1} +(n-1)d[/tex]
[tex]a_{n}[/tex] --> value of the nth number of the sequence[tex]a_{1}[/tex] --> first term of the sequencen --> position of the nth termd --> common differenceLet's examine the information given:
first term a = 5⇒ [tex]a_{1} =5[/tex]
common difference d = 2⇒ d = 2
Therefore the equation for finding the nth term of the sequence so far is:
[tex]a_{n}=5+(n-1)*2=5+2n-2=3+2n[/tex]
Now we want to find how many terms this sequence must be added to get 1440
General equation for adding all the terms = [tex]\frac{n(a_{1}+a_{n} ) }{2}[/tex]
[tex]a_{1}[/tex]: first term of the sequence[tex]a_{n}[/tex]: last term of the sequencen: number of terms in the sequence.Using all the information given, let's plug in the all the values:
[tex]1440=\frac{n*(5+(3+2n))}{2} \\1440=\frac{n*(8+2n)}{2} \\2880=8n+2n^2\\2n^2+8n-2880=0\\(2n+80)(n-36)=0[/tex]
To solve this we set (2n + 80) = 0 and (n-36) = 0
[tex]2n+80=0\\ 2n = -80\\n= -40[/tex] [tex]n - 36 =0\\n = 36[/tex]
In this case, n can only equal 36 since n cannot be negative.
Answer: 36 terms of this sequence must be added to get 1440.

To the nearest cent, how much will she have in 2 years?
Assuming that no transaction happens in her account for those 2 years, the amount that Brooke will have in 2 years for given case is $8.47
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
We're specified that:
Initial amount in bank of Brooke = p = $7Interest rate = r = 10% = 0.10 (in decimal form), compounding annually.Due to annual appliance of the interest, we have n = 1The time for which this compounding will be done is t = 2 years.Thus, we get the final amount's value (after 2 years of compounding) for this case as :
[tex]a = p(1 + \dfrac{r}{n})^{nt}\\\\a = 7(1 + 0.10)^2 = 7 \times (1.1)^2 = 7 \times 1.21 = 8.47 \: (\rm in \: dollars)[/tex]

A basketball player shoots a free throw, where the position of the ball is modeled by x = (24cos 48°)t and y = 6.1 + (24sin 48°)t − 16t 2. What is the height of the ball, in feet, when it is 13 feet from the free throw line? Round to three decimal places.
I know how to do this but I keep getting a negative answer, is there an error with the question or am I just doing it wrong
Maybe ur just not seeing the negative comment on this and tell me which way u are solving it and then i can help.
The height of the ball is 10.053 approx. when it is 13 feet from the free throw line .
What is free throw?
The physics aspect of shooting a free throw involves distance and deviation. Distance is determined by two factors: launch angle and launch speed. Players have a choice between shooting for a larger target by using more arc or going for a shooter's touch and shooting with their ideal arc for their height.
According to the question
A basketball player shoots a free throw, where the position of the ball is modeled
x = (24cos 48°)t
y = 6.1 + (24sin 48°)t − [tex]16t^{2}[/tex]
now
13 feet from the free throw line
x = 13 feet (horizontal distance)
x = (24cos 48°)t
(24cos 48°)t = 13
t ≈ 0.8059
putting values in y to get the vertical height
y = 6.1 + (24sin 48°)t − [tex]16t^{2}[/tex]
y = 6.1 + (24sin 48°)*0.8059 − [tex]16*( 0.8059)^{2}[/tex]
y ≈ 10.053
Hence, the height of the ball is 10.053 approx.

find the circumference of the circle whose diameter is 14 cm
Circumference of the circle with diameter 14 cm is 43.96 cm.
What is the circumference?Circumference of any shape or figure is the total length of it's boundary. Circumference of a shape is also called the perimeter.
Circumference of any shape can be calculated by opening that shape into a straight line and then measuring the length of the line.
Perimeter of the circle can be computed by the formula,
C = 2πr, where r is the radius of the circle.
So, diameter of the circle is 2r
Here, we have, diameter = 2r = 14 cm
∴Circumference = 14π = 43.96 cm

Step-by-step explanation:
∠3 and ∠6 are supplementary because they are same-side interior angles. Therefore, the correct answer is option A.
From the given figure, m and n are parallel lines and l is transversal.
Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.
Here, angle 3 and angle 6 are co-interior angles and sum of their angles is supplementary.
