The mean length of 10 childrens' big finger is 8.1cm.
The mean length of 11 adults' big finger is 14.1cm.
What is the mean length (rounded to 2 DP) of these 21 people's big finger?
Answer:
The mean length of 10 children's big finger is 8.1 cmAverage length of all the 10 children's finger is (8.1×10) cm = 81 cm.
The mean length of 11 adult's big finger is 14.1 cmAverage length of all the 11 adult's big finger is (14.1×11) cm =155.1
Mean length of these 21 people's big finger is[tex] \frac{(81 + 155.1)}{21} = 11.242857[/tex]Hence, 11.24 is the right answer.Solve for x. Enter the solutions from least to greatest.
(x+15)^2-10=0
Answer:
lesser x = -1.84lesser x = -8.16Step-by-step explanation:
Given the expression
[tex]\left(x+5\right)^2-10=0[/tex]
Add 10 to both sides
[tex]\left(x+5\right)^2-10+10=0+10[/tex]
Simplify
[tex]\left(x+5\right)^2=10[/tex]
[tex]\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
solve
[tex]x+5=\sqrt{10}[/tex]
Subtract 5 from both sides
[tex]x+5-5=\sqrt{10}-5[/tex]
[tex]x=\sqrt{10}-5[/tex]
[tex]x=-1.8[/tex]
so
[tex]x+5=-\sqrt{10}[/tex]
Subtract 5 from both sides
[tex]x+5-5=-\sqrt{10}-5[/tex]
Simplify
[tex]x=-\sqrt{10}-5[/tex]
[tex]\:x=-8.2[/tex]
As -1.84 > -8.16
so
lesser x = -1.84lesser x = -8.16Melanie works at a frozen yogurt stand after school. The stand sells fruit and yogurt smoothies for $3.00 each and soft-serve cones for $2.00 each. On a hot summer day, the stand sold 12 more smoothies than soft-serve cones for total sales of $206. Which of the following systems of equations could be used to find s
s
, the number of smoothies, and c
c
, the number of cones the shop sold that day?
Answer:
3s+2c=206
s=c+12
Step-by-step explanation:
3.00(smothies,s) + 2.00(cones,c) = $206 (total)
s,smoothies = c,cones + 12
-5(t + 3)= -30
Solve for the variable!! Please
Answer:
[tex]\huge\boxed{t=3}[/tex]
Step-by-step explanation:
[tex]-5(t+3)=-30[/tex]
METHOD 1:[tex]-5(t+3)=-30[/tex] divide both sides by (-5)
[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]
[tex]t+3=6[/tex] subtract 3 from both sides
[tex]t+3-3=6-3\\t=3[/tex]
METHOD 2:[tex]-5(t+3)=-30[/tex] use the distributive property a(b + c) = ab + ac
[tex](-5)(t)+(-5)(3)=-30[/tex]
[tex]-5t-15=-30[/tex] add 15 to both sides
[tex]-5t-15+15=-30+15[/tex]
[tex]-5t=-15[/tex] divide both sides by (-5)
[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

How can you write the equation for a linear function if you know only two ordered pairs for the function? Drag tiles tho complete the explanation. Tiles may be used once, more than once, or not at all.
Answer:
Explanation below
Step-by-step explanation:
First determine the slope using (y2-y1)/(x2-x1)
Then set up point slope form and add in an ordered pair for x and y to determine the y intercept: y - y1 = m(x - x1). Solve for y and you'll end up with slope intercept form.
For example: (-2,1), (3,2) find slope and y intercept.
(2-1)/(3-(-2))= 1/5
y-2=.2(x-3)
y=.2x-.6+2
y=.2x+1.4 or y=(x/5)+(7/5)

the answer is 4.5 but you cannot plant 4 and a half seeds. so the answer would be 3.
Step-by-step explanation:
Answer:
3x + 9
Step-by-step explanation:
You basically want the total amount of seeds so if he plants x in one garden and 2x + 9 in another, you add them both
x + 2x + 9
Equals 3x + 9
2x+3y=4 y+3x=6
find x and y
Answer:
x=-3/2y+2
y= y=−3x+6
Step-by-step explanation:
solve for x.
2x+3y=4
Add -3y to both sides.
2x+3y+−3y=4+−3y
2x=−3y+4
Divide both sides by 2.
2x/2= -3+4/2
x= -3/2 y+2
solve for y.
y+3x=6
Add -3x to both sides.
3x+y+−3x=6+−3x
y=−3x+6

Answer:
Student B
Step-by-step explanation:
Proportional relationship means that it follows a certain pattern or is constant.
Student B was the only relationship to be constant as it goes by multiples of 6.
Ex. 6, 12, 18, 24, 30.
Answer:
Student B
Step-by-step explanation:
Student B's wages increase by 6 each time, but Students A, C, and D do not steadily increase. The steady increase of 6 for Student B is what makes their wages proportional.
Rewrite the equation 6x – 9y = 12 in terms of y.
Answer:
Step-by-step explanation:
6x - 9y = 12
subtract 6x from both sides
-9y = 12 - 6x
divide both sides by -9
y = -4/3 + 2/3x
or
y = 2/3x - 4/3
The equation 6x – 9y = 12 written in terms of y is; y = (2/3)x - 4/3
We are required to write the equation 6x – 9y = 12 in terms of y.Rewriting the equation 6x – 9y = 12 in terms of y is as follows;
6x – 9y = 12 6x - 12 = 9yDivide through by 9 so that we have;
y = (2/3)x - 4/3

Find two consecutive even integers such that the sum of the smaller and 3 times the larger is 330
I am so stuck please any one help
Answer:
The 2 numbers = 81 and 83
Step-by-step explanation:
As, one number = x
The other, because it's an even number and consecutive = x + 2
So the larger numbef here is x + 2
And they are saying 3 times x + 2 plus x = 330
So let's solve!
3 times x + 2 = 3(x+2) = 3x + 6
So we will add it to x = (3x + 6) +(x) = 4x + 6
So they are saying the sum of them will be 330
So, 4x + 6 = 330
4x = 330 - 6
4x = 324
x = 324/4
x = 81
So x is the first number = 81
And the second is x + 2 = 81 + 2 = 83
So the 2 numbers are 81, 83
Lets check!
3 times the bigger number = 83 x 3 = 249
We will add it to 81 and we will get 330
So, 249 + 81 = 330
So the answer is right

When simplified it changes back, (2x+5)^2
Step-by-step explanation:
Answer:
4x² + 20x + 25
Step-by-step explanation:
Given
(2x + 5)²
= (2x + 5)(2x + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x + 5) + 5(2x + 5) ← distribute both parenthesis
= 4x² + 10x + 10x + 25 ← collect like terms
= 4x² + 20x + 25
