Which point shows the number with the greatest absolute value? А B + + D TH 30 40 50 -50 -40 -30 - 20 -10 0 10 20 O Point A O Point B O Point C O Point D ہ
We are shown points A, B, C, and D on a number line.
We are asked to find out which point shows the number with the greatest absolute value?
Recall that the absolute value of a number is always positive.
The negative values of points A and B will become positive.
As you can see from the number line, point A is closer to -40 and the point D is closer to 30
The absolute value of point A will be closer to |-40| = 40
Since 40 is greater than 30, point A shows the number with the greatest absolute value.
Therefore, the correct answer is Point A.

[tex]undefined[/tex]Hi, what is the LCM of the numbers 3 and 15
Answer:
15
Step-by-step Explanation:
LCM is the least common multiple, that is, is the least number that is a multiple of both numbers.
To find it, first, let's write the multiples of 3:
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...
Now, let's write the multiples of 15:
Multiples of 15: 15, 30, 45, ...
If you compare the multiples of 3 and 5, we can see that they have some common multiples, as 15 and 30.
From this common multiples, 15 is the smallest number. So, 15 is the LCM of 3 and 15.

Callie's grandmother pledged R150, 00 for every mile Callie walked in her walk-a-thon. Callie walked 14.5 km. How much does her grandmother owe? ( assume 8 km = 5miles)
Given:-
Callie walked 14.5 km. And also given 8 km=5 miles.
At first we convert 14.5 km to miles. we get,
[tex]\begin{gathered} 14.5\times\frac{5}{8}=\frac{72.5}{8} \\ \text{ =9.0625} \end{gathered}[/tex]So 14.5 km is 9.0625 miles.
Callie's grandmother pledged Rs. 150 for every mile. so for 9.0625 miles it is,
[tex]9.0625\times150=1359.375[/tex]So her grandmother owe Rs. 1359.375

First, we will find the product of AB as follows:
[tex]AB=\begin{bmatrix}{10} & {4} & {0} \\ {1} & {3} & {1}\end{bmatrix}\cdot\begin{bmatrix}{4} & {1} & \\ {2} & {2} & {} \\ {0} & {-1} & \end{bmatrix}=\begin{bmatrix}{10\cdot4+2\cdot4+0\cdot0} & {1\cdot01+4\cdot2+0\cdot-1} & {} \\ {1\cdot4+3\cdot2+1\cdot0} & {1\cdot1+3\cdot2+1\cdot-1} & {} \\ {} & {} & {}\end{bmatrix}[/tex]simplifying the answer:
[tex]AB=\begin{bmatrix}{48} & {18} & {} \\ {10} & {6} & {} \\ {} & {} & {}\end{bmatrix}[/tex]Now, we will add the unity matrix to the answer:
[tex]AB+I=\begin{bmatrix}{48} & {18} & {} \\ {10} & {6} & {} \\ {} & {} & {}\end{bmatrix}+\begin{bmatrix}{1} & {0} & {} \\ {0} & {1} & {} \\ {} & {} & {}\end{bmatrix}=\begin{bmatrix}{49} & {18} & {} \\ {10} & {7} & {} \\ {} & {} & {}\end{bmatrix}[/tex]So, the answer will be option D

How many pounds of candy that sells for $0.85 per Ib must be mixed with candy that sells for $1.22 per lb to obtain 9 lb of a mixture that should sell for $0.92 per lb? 50.85-per-lb candy: 73 lb (Type an integer or decimal rounded to two decimal places as needed.) $1.22-per-b candy
This system gives two equations
[tex]\frac{0.85x+1.22y}{9}=0.92[/tex][tex]x+y=9[/tex]where x is the number pounds of $0.85/lb candy and y is the number of pounds of $1.22/lb candy.
The solution to the system is
[tex]x=7.297[/tex][tex]y=1.70[/tex]Hence, 7.297 lb of $0.85 candy is required in order that if we mix them with 1.70 lb of $1.22 candy, we will get a 9 lb solution of 0.92 /lb candy.
The gas/oil ratio for a certain chainsaw is 50 to 1.a. How much oil (in gallons) should be mixed with 13 gallons of gasoline? b. If 1 gallon equals 128 fluid ounces, write the answer to part a in fluid ounces.
1) We can write the following ratio for this, considering the ratios and the quantities:
a)
[tex]\begin{gathered} \frac{50}{1}=\frac{13}{x} \\ 50x=13 \\ x=\frac{13}{50}\text{ (or 0.26g)} \end{gathered}[/tex]Notice that on the left side, the ratio gas/oil, and on the right side is the quantity of gas and the unknown quantity of oil.
So, so far we have 13/50 gallons of oil that must be mixed with gasoline.
b) For now, we need to convert that from gallons to fluid ounces so we can write out the following product:
[tex]\begin{gathered} x=\frac{13}{50}\times128 \\ x=33.28fl\text{ oz} \end{gathered}[/tex]So 13/50 or 0.26 gallons of oil. b) 33.28 fl oz.

determine whether the binomial expression is a factor to the following polynomial.[tex]p(x) = {x}^{3} - 9x + 1 \: \: \: \: \: \: \: \: \: (x - 3)[/tex]the binomial expression is (x-3) ^^answer choicesA. yesB. no
We can find if (x-3) is a factor by dividing P(x) by (x-3).
A simpler way is replacing x with 3 and if the value of P(x) is 0, then (x-3) is a factor of P(x). This is because x=3 is a root of P(x) and therefore it can be factorized with the term (x-3).
Then, we calculate P(3):
[tex]P(3)=3^2-9\cdot3+1=9-27+1=-17[/tex]As x=3 is not a root of P(x), then (x-3) is not a factor of P(x).
Answer: No.

Remember that
the sum of the interior angles in any polygon is equal to
S=180(n-2)
where
n is the number of sides of polygon
In this problem
we have
n=6 (hexagon)
so
substitute
S=180(6-2)
S=720 degrees
step 2
Adds the interior angles
720=120+(5x-6)+(4x+14)+(7x)+(8x-8)+(6x)
solve for x
combine like terms
720=30x+120
30x=720-120
30x=600
x=20Moshde runs a hairstyling business from her house. She charges $42 for a haircut and style. Her monthly expenses are $1070. She wants to be able to put at least $1,249 per month into her savings account order to open her own salon. How many "cut & styles" must she do to save at least $1,249 per month?
ANSWER:
56 cut & styles
STEP-BY-STEP EXPLANATION:
They tell us that each haircut and style charges $42 and that the monthly expenses are $1070, he wants to save a total of $1249, with this information we can establish the following equation:
[tex]42x-1070=1249[/tex]Where x would be the amount of cut & styles, we solve for x:
[tex]\begin{gathered} 42x=1249+1070 \\ x=\frac{2319}{42} \\ x=55.2 \\ x\cong56 \end{gathered}[/tex]If you make a total of 55 cut & styles, the amount does not reach a total of $1249 per month, therefore, at least 56 cut & styles are needed, to achieve the monthly goal.

Write a quadratic equation with 7 and 2/5 as its roots. Write the equation in the form ax2 + bx+c= 0, where a, b, and c are integers.
As given by the question
There are given that the roots: 7 and 2/5.
Now,
Since the roots are integers, we can write the equation in the given form using a = 1.
Then,
b is the opposite of the sum of the roots
So,
[tex]\begin{gathered} b=-((7)+(\frac{2}{5})) \\ b=-(\frac{35+2}{5}) \\ b=-\frac{37}{5} \end{gathered}[/tex]And
c is the products of the roots
So,
[tex]\begin{gathered} c=7\times\frac{2}{5} \\ c=\frac{14}{5} \end{gathered}[/tex]Now,
The desired quadratic equation is:
[tex]\begin{gathered} ax^2+bx+c=0 \\ x^2-\frac{37}{5}x+\frac{14}{5}=0 \\ 5x^2-37x+14=0 \end{gathered}[/tex]Hence, the correct option is A.
Amelia bought spider rings for Halloween goodie bags. She bought 13 packs of red rings, 16 packs of yellow rings, and 14 packs of green rings. If each pack had 12 rings, how many rings did Amelia buy?
We know that
• She bought 13 packs of red rings.
,• She bought 16 packs of yellow rings.
,• She bought 14 packs of green rings.
,• Each pack has 12 rings.
This problem is about multiplication, notice that each pack includes 12 rings, that means we need to multiply each pack by 12, in order to find the total number of rings of each color.
[tex]R=13\cdot12=156[/tex]There are 156 red rings.
[tex]Y=16\cdot12=192[/tex]There are 192 yellow rings.
[tex]G=14\cdot12=168[/tex]There are 168 green rings.
Now, we sum all these numbers to find the total
[tex]T=168+192+156=516[/tex]Therefore, there are 516 rings in total.
