HURRY!!!! Right now, Molly is twice as old as Nancy. Zander is 6 years younger than Molly. Which expression represents Molly’s current age in
terms of Nancy’s? Which expression represents Molly’s current age in
terms of Zander’s? Nancy is currently 10 years old, and Zander is 14. How old is Molly?
Answer:
:)
Step-by-step explanation:
Let 'N' rep. Nancy's age
Let 'M' rep. Molly's age
1) 2N
2) M - 6
3) 2(10) = 20
therefore, Molly is 20
M = 20
M - 6 = 14 (Zander's age)
Answer:
Which expression represents Molly’s current age in terms of Nancy’s?
Answer: 2n

The formula for the speed of a tsunami in deep water is v=gh−−√ , where g is acceleration due to gravity, 9.8 m/s2 , and h is the depth of the ocean in meters. Use this formula to estimate the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.
Answer:
v = 200 m/s
Step-by-step explanation:
The formula for the speed of a tsunami in deep water is given by :
[tex]v=\sqrt{gh}[/tex]
Here,
g is acceleration due to gravity
h is the depth of the ocean in meters.
We need to find the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.
It means we need to find v if h = 4000 m
So,
[tex]v=\sqrt{10\times 4000}\\\\v=200\ m/s[/tex]
So, the speed of the tsunami is 200 m/s.
-1 1/5 + -3/5 in simplest form

-1 4/5
Step-by-step explanation:
In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction 3 5, the numerator is 3, and the denominator is 5. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.
2x - 3y = 8 //
Find y
Answer:
[tex]y = -\frac{2}{3} x - \frac{8}{3}[/tex]
Step-by-step explanation:
[tex]2x - 3y = 8\\[/tex]
Isolate y
[tex]-3y = 8-2x\\-3y = -2x+8[/tex]
Divide both sides of the equation by -3
[tex]\frac{-3y}{-3} = \frac{2x}{-3} +\frac{8}{-3} \\\\y = -\frac{2}{3} x - \frac{8}{3}[/tex]
Solve for a
2(a+5)=-2 Steps too please ❤️
Answer:
a=-6
Step-by-step explanation:
2(a+5)=-2 Step 1 distribute
2a+10=-2 Step 2 minus 10 on both sides
2a=-12 Step 3 divide but 2 on both sides
a=-6
Answer:
a=-6
Step-by-step explanation:
In order to solve for a, we must isolate a on one side of the equation.
[tex]2(a+5)=-2[/tex]
2 is being multiplied by (a+5). The inverse of multiplication is division. Divide both sides of the equation by 2.
[tex]2(a+5)/2=-2/2[/tex]
[tex](a+5)=-2/2[/tex]
[tex](a+5)=-1[/tex]
5 is being added to a. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.
[tex]a+5-5=-1-5[/tex]
[tex]a=-1-5[/tex]
[tex]a=-6[/tex]
Let's check our solution. Plug -6 in for a and solve.
[tex]2(a+5)=-2[/tex]
[tex]2(-6+5)=-2[/tex]
[tex]2(-1)=-2[/tex]
[tex]-2=-2[/tex]
This checks out, so we know our solution is correct.
The solution to the equation 2(a+5)=-2 is a=-6

The question is incomplete:
1. A cosmetologist must double his/her salary before the employer con realize any profit from his/her work, Miss, Mead paid Miss, Adams $125,00 per week to start.
2. Miss. Mead pays Miss. Brown $125.00 per week. How much money must Miss. Brown take in for services if Miss. Mead is to realize $50.00 profit on her work? (Conditions on salary are the same as in problem 1)
ODS
a. $275.00 b. $325.00 c. $250.00 d. $300.00
Answer:
d. $300.00
Step-by-step explanation:
Given that a cosmetologist must double her salary before the employer can realize any profit from his/her work, for Miss. Mead to realize $50.00 profit on her work, you would have to determine the amount that doubles the salary of the cosmetologist and add the $50 needed as profit:
Salary= $125*2=$250
$250+$50= $300
According to this, the answer is that for Mead to realize $50.00 profit on her work, Miss. Brown must take $300.

(I WILL MARK AS BRAINLIEST PLS OPEN I RLLY NEED TO KNO PLSSS) a hot air balloon is 10 meters above the ground and rising at a rate of 15 meters per minute. another balloon is 150 meters above the ground and descending at a rate of 20 meters per minute. when will the two balloons meet? i really need to know im super confused and also use the either the substitution method or the elimination method to solve this word problem PLSSSSSSSSSSSSSSSSSSSSS
Answer:
After 4 minutes
Step-by-step explanation:
Balloon 1
Initial position = 10 mRise rate = 15 m/minBalloon 2
Initial position = 150 mDrop rate = 20 m/minTime required for the balloons to meet = x
After x minutes the first balloon will be at position:
10 + 15xAnd the second balloon will be at position:
150 - 20xSince they meet after x minutes, their position must be same:
10 + 15x = 150 - 20x15x + 20x = 150 - 1035x = 140x = 140/35x = 4 minutesSo the balloons will meet after 4 minutes

h(n)=4n+ 4 find h (-3)
Step-by-step explanation:
h(n)=4n+ 4 find h (-3)
h(-3)=4(-3)+4
=-12+4
=--8
Answer: -8
Step-by-step explanation: h(n) = 4n + 4 means that
if we put an n into our function, a 4n + 4 comes out.
So here, we're putting a -3 into our function which means that
a 4(-3) + 4 comes out which simplifies to -12 + 4 or -8.
So h(-3) = -8 or the value of the function at -3 equals -8.

Answer:
Commutative property of multiplication
Step-by-step explanation:
This property states that numbers can be switched around when multiplying and the answer still remains the same
Answer:
C
Step-by-step explanation:
So we have the expression:
[tex]63\cdot 3[/tex]
And Jared rewrote it as:
[tex]3\cdot 63[/tex]
In other words, he just switched the order and the expression remains equivalent.
This is an example of the commutative property of multiplication, which states that if you change the order of a multiplication sentence, the sentence will remain equivalent.
So, our answer is C.
And we're done!

Hi Geovannie, when you submit this form,
Required
1. Solve the equation:
-(1+4x)=4(1-x)-5*
(5 Points)
Steps to solve:
-(1 + 4x) = 4(1 - x) - 5
~Distribute both sides
-1 - 4x = 4 - 4x - 5
~Combine like terms on the left side
-1 - 4x = -1 - 4x
~Add 4x to both sides
-1 = -1
~Add 1 to both sides
0 = 0
Therefore, all real numbers are solutions.

Airboats are a popular way to tour areas with shallow water. A small airboat can fit 6 people. A large airboat can fit 4 times as many people. How many more people can fit in a large airboat than in a small airboat?
Answer:
18
Step-by-step explanation:
Small airboat = 6
Large airboat = 4× the small airboat's capacity = 4×6= 24
thus 24-6 = 18 more people can fit in the large airboat
Help??? WILL MARK YOU BRAINLIEST
Answer:
13) Luis is wrong because he read the 80* as if his starting point was P. He needs to now take away 45 because that is the angle PTQ.
14) 165* I'm pretty sure because you just do 45 plus 60 since the centred one would only have a view of 45 from what I understand and the other two still have a view of 60 each. Total is 165.
Answer:
8. AC = 29
x = 6
AB = 6
9. BC = 15
3x = 15
x = 5
BD = 3x +4x-13
= 22
10. <PTR = 80
11. < PTQ = 45
12. <QTS = 130 - 45 = 85
13. Luis didn't subtract 80 by 40
14. 180
Maggie’s brother is 3 years younger than four times her age the sum of their ages is 27
well i think maggie would be 6
Step-by-step explanation:
6•3=18
18-4=14
14+6=20
Answer:
[tex]\huge\boxed{\text{Maggie = 6 years, Brother = 21 years}}[/tex]
Step-by-step explanation:
We can create two equations based on the word problems, where [tex]m[/tex] is Maggie's age and [tex]b[/tex] is her brother's age.
[tex]m + b = 27[/tex]
[tex]b = 4m - 3[/tex]
We can now substitute [tex]4m-3[/tex] in as [tex]b[/tex] into [tex]m+b=27[/tex].
[tex]m + (4m-3) = 27\\\\5m - 3 = 27\\\\5m = 30\\\\m = 6[/tex]
Now that we know the value of [tex]m[/tex], we can substitute it into [tex]m+b=27[/tex].
[tex]6 + b = 27\\\\b = 27-6\\\\b = 21[/tex]
Hope this helped!

The cuboid has volume 288cm^3 (a) the cuboid has a length 12 cm and a width 5cm Calculate the height of the cuboid (b) 1cm^3 of the cuboid has a mass of 4g Work out the mass of the cuboid. Please help I am desperate
Answer:
height= 4.8cm
Step-by-step explanation:
volume= length×width× height given the volume and length and width, 288=12×5×h
288=60h
divide both sides by 60
h=4.8cm
h = 4,8 cm
m = 1152 g
Step-by-step explanation:V = l×w×h
h = V/l×w
= 288cm³/12cm×5cm
= 288cm³/60cm²
= 4,8 cm
1cm³ .............. 4g
288cm³ ........ xg
x = 288cm³×4g/1cm³ = 1152 g
