What is the value of the missing exponent in the equation 7.4 ÷ 10= 0.074?
the answer is 0.74 not 0.074
Step-by-step explanation:
7.4 ÷ 10 = 0.74Explain what needs to be fixed.
2n + 10 = -2
2n = 12 Step one
n = 6 Step two
Answer:
step one needs to be fixed... you are supposed to subtract 10 from both sides of the equation.
Step-by-step explanation:
STEP 1: Move all terms not containing n to the right side of the equation.
[tex]2n=-12[/tex]
STEP 2: Divide each term by 2 and simplify.
[tex]n=-6[/tex]
Two printers working together can complete a job in 6 hours. Working alone, one
printer takes three times as long as the other printer. How many hours would each
printer need to complete the job alone?
Answer:
Press A takes 10 hours to do a certain job. So Press A does (1/10)th of the job in an hour.
Press A and Press B, together do (1/2.5) or (4/10)th of the job in an hour.
So Press B does (4/10)-(1/10) = (3/10)th of the job in an hour. So Press B can do the job in (10/3) hours or 3 hour and 20 mins.
Check: A does (1/10)th and B does (3/10)th part of the job in an hour. A and B together will take (1/10)+(3/10) = 4/10th of the job in an hour. So they will complete the job in 10/4 = 2.5 hours. Correct.
Answer: Press B can do the job in 3 hour and 20 mins.

An iron bar is heated. Its length, L, in millimetres can be modelled by a linear function, L=mT+c, where T is the temperature measured in degrees Celsius (°C).
At 150°C the length of the iron bar is 180 mm.
Write down an equation that shows this information.
4b.
At 210°C the length of the iron bar is 181.5 mm.
Write down an equation that shows this second piece of information.

what is the sum of the first five terms of the geometric sequence in which a1=5 and r=1/5
express your answer as an improper fraction.
Answer:
Sum of the first five terms of the geometric sequence in which a1=5 and r=1/5 is [tex]\mathbf{S_n=\frac{781}{125} }[/tex]
Step-by-step explanation:
We need to find sum of the first five terms of the geometric sequence in which a1=5 and r=1/5
The formula used to find sum of the geometric sequence is: [tex]S_n=\frac{a(r^n-1)}{r-1}[/tex]
Where a is the first term, r is the common ratio and n is the number of terms
Now finding sum of the first five terms of the geometric sequence
We have a=5, r=1/5 and n=5
Putting values in the formula:
[tex]S_n=\frac{a(r^n-1)}{r-1}\\S_n=\frac{5((\frac{1}{5}) ^5-1)}{\frac{1}{5}-1}\\S_n=\frac{5(\frac{1}{3125}-1)}{\frac{1-5}{5}}\\S_n=\frac{5(\frac{1-3125}{3125})}{\frac{-4}{5}}\\S_n=\frac{5(\frac{-3124}{3125})}{\frac{-4}{5}}\\S_n=5(\frac{-3124}{3125})}\times{\frac{-5}{4}}\\S_n=\frac{781}{125}[/tex]
So, sum of the first five terms of the geometric sequence in which a1=5 and r=1/5 is [tex]\mathbf{S_n=\frac{781}{125} }[/tex]

Alaina is making a birdseed mix with 2 1/3 lb sunflower seeds, 5/6 lb cracked corn, and 1/6 lb peanuts. How much cracked corn does Alaina need to make 5 lb of birdseed mix? Show your work.
Answer:1.25
Step-by-step explanation:
If you add everything it makes 3 and 1/3 pounds you want 5
If you divide 5 by 3 and 1/3 it's 1.5
Then you just need to multiply 5/6 by 1.5
For making 5 lb birdseed mix 1 ¹/₄ lb cracked corn will be used.
What is proportion ?
A proportion is an equation based on the equality of two ratios.
Here it is given that :
Alaina is making a birdseed mix with 2 1/3 lb sunflower seeds, 5/6 lb cracked corn, and 1/6 lb peanuts.
adding everything to make birdseed mix = 2 1/3 + 5/6 + 1/6 =10/3 lb
Now,
for making 10/3 lb birdseed mix = 5/6 lb cracked corn is used
in other words :
for making 1 lb birdseed mix = (5/6) x (3/10) lb cracked corn is used
that is , for making 5 lb birdseed mix = (5/6) x (3/10) x 5 lb cracked corn will be used.
= 15/12 = 5/4 = 1 ¹/₄ lb cracked corn will be used.
Therefore, for making 5 lb birdseed mix 1 ¹/₄ lb cracked corn will be used.

Need help with geometry.
Answer:
x = 23
Step-by-step explanation:
m<1 and m<3 will be the same because they are vertical
m<3 and m<5 will be the same (I forgot their relationship)
which means m<5 and m<7 will be the same
which ALSO means that m<1 =7
So you know that m<1 = m<7 (4x -6 = 2x +40)
x = 23

a piece of wire is 28cm in length is cut into two parts, each part bend to make a square. given that area of square is 416m^2. find the perimeter of each square.
Answer:
25.488 cm and 2.512 cmStep-by-step explanation:
Note: the area of squares is 41 cm² but not 416 m², typo
Let the sides of squares be x and y
Based on given we have equations:
4x + 4y = 28x² + y² = 41Simplify the first equation
4x + 4y = 28x + y = 7x = 7 - ySubstitute x to solve for y:
(7 - y)² + y² = 4149 - 14y + y² + y² = 412y² - 14y + 49 - 41 = 02y² - 14y + 8 = 0y² -7y + 4 =0Solving we get:
y= 6.372 cm or y= 0.628cmThen
x = 0.628 cm or x = 6.372 cmPerimeter of each square is:
4*6.372 = 25.488 cmand
4*0.628 = 2.512 cmFind the value of 2x+y when x=4 and y3
Answer:
11
Step-by-step explanation:
Replace the values of x and y into the equation.
2(4) + 3 = 8 + 3
