Answer:
76
Step-by-step explanation:
For age 'a', the special number was supposed to be ...
2a +4
Tammi's mother actually calculated it as ...
2(a +4) = 2a +8
a value that is (2a+8) -(2a+4) = 4 more than it was supposed to be.
The special number was supposed to be 80 -4 = 76.

The lights go out, your bedroom is pitch dark, yet you still need to find a pair of socks, in your drawer there is 25 white socks and 25 red socks how many socks do you need to pull out before you get a matching pair?
Answer: At most 3
Step-by-step explanation:
If there are 25 white socks and 25 red socks, a matching pair would be picked in at most 3 times.
The first sock you pick would be either White or Red
The second sock you pick would be either white or red again which means that you now either have 2 whites, 2 reds or 1 white and 1 red.
The third sock you pick will either be white or red once more. At this point you will either have 3 whites, 3 reds, 2 whites and 1 red or 2 reds and 1 white.
You will therefore have at least a matching pair after 3 tries.

C. square 2
D. square 2 / 2
Answer:
sin90° = 1.
Step-by-step explanation:
Using the diagram, we notice that the side opposite of the 90° angle is the hypotenuse itself.
Therefore sin90° = Hypotenuse/Hypotenuse = 1.

Arisia puts $500 into a savings account with an annual simple interest rate of 4.5%. If the savings account pays 5% simple interest, how much interest will Arisia earn on her $500 principal over 20 years?
Answer:
$500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 500 × 0.05 × 20 = 500
I = $ 500.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 5% per year
for 20 years is $ 500.00.

5). Amount payable by the customer = 1416 Rs.
Step-by-step explanation:
4). [tex](\frac{3}{7})\times (-\frac{5}{8})\div (\frac{1}{3}\times \frac{5}{6})[/tex]
= [tex](-\frac{15}{56})\div (\frac{5}{18})[/tex]
= [tex](-\frac{15}{56})\times \frac{18}{5}[/tex]
= [tex]-\frac{54}{56}[/tex]
= [tex]-\frac{27}{28}[/tex]
5). Cost of the item = Rs 1200
G.S.T. applicable on this item = 18%
Amount to be paid for G.S.T.= 1200 × [tex]\frac{18}{100}[/tex]
= Rs 216
Total amount payable by the customer = Cost + G.S.T.
= 1200 + 216

the ratio of the heights of two similar pyramids is 2:5 in the volume of the smaller pyramid is 100 cubic feet, find the volume of the large pyramid
Volume is a cubic measurement.
Set up a ratio of volume to the ratio of the height:
100/v2 = 2^3/5^3
V2 = 100 x 5^3/2^3 = 100 x 125/8 = 1,562.5 cubic feet
The volume of large pyramid is 1,562.5 cubic feet, by using ratio of heights.
Volume of pyramid based problem:What information do we have?
Ratio of heights of two similar pyramids = 2:5
Volume of smaller pyramid = 100 cubic feet
Volume of smaller pyramid / Volume of large pyramid = Height of smaller pyramid³ / Height of large pyramid³
100 / Volume of large pyramid = 2³ / 5³
Volume of large pyramid = 125(100) / 8
Volume of large pyramid = 1,562.5 cubic feet

What is the measure of
Answer:
The measure of Angle B = 82
Step-by-step explanation:
⁕We have to calculate the angle for A.
‣Notice how angles A is on a straight angle, a straight angle equals 180 degrees by the way.
⁕You are going to subtract 143 from 180.
[tex]180 - 143 = 37[/tex]
‣So the angle of A is 37. A triangle equals 180 degrees.
⁕You are going to combine angle A and Angle C and subtract it from 180, to find angle B.
[tex]61 + 37 = 98 \\ 180 - 98 = 82[/tex]
‣Therefore, angle B equals 82.

Mrs. Smith bought 6.5 metres of lace. She used 1.3 metre to make a dress. She used the rest to make 4 cushions of the same size. How much lace did she use for each cushion, giving your answer in centimetres?
Mrs. Smith used 130 centimeters of lace for each cushion.
What are mathematical operations?Calculating a value using operands and a math operator is referred to as performing a mathematical "operation." The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers. There are five fundamental operations in mathematics: addition, subtraction, multiplication, division, and modular forms.
Given Mrs. Smith bought 6.5 meters of lace. She used 1.3 meters to make a dress. She used the rest to make 4 cushions of the same size.
Lace bought by Mrs. smith = 6.5 meters
Since she used lace in the dress = 1.3 meters
remaining lace = 6.5 - 13
remaining lace = 5.2 meters
Since she used the remaining lace to make four cushion
thus, lace required for every cushion = 5.2/4 = 1.3
therefore, she used for each cushion 130 centimeters of lace.

what is the quotient (3x^2 + 8x -3) divided by (x + 3)
Answer:
Quotient = (3x-1)
Step-by-step explanation:
we need to find the quotient when (3x² + 8x -3) is divided by (x+3)
It means we need to divide (3x² + 8x -3) by (x+3).
We can write it as follows :
[tex]\dfrac{3x^2 + 8x -3}{(x+3)}[/tex]
Applying middle term splitting on the numerator.
[tex]\dfrac{3x^2 +9x-x-3}{(x+3)}\\\\=\dfrac{3x(x+3)-1(x+3)}{(x+3)}\\\\=\dfrac{(3x-1)(x+3)}{(x+3)}\\\\=(3x-1)[/tex]
So, the required quotient is (3x-1)

Find the values of p and q given that 12x² - 13x - 7175 = (x-p) (qx + 287)
Answer:
[tex]p=25,\\q=12[/tex]
Step-by-step explanation:
In [tex](ax+b)(cx+d)=acx^2+bcx+dax+bd[/tex], notice the third term of the quadratic in standard form is formed entirely by [tex]b\cdot d[/tex].
Therefore, in [tex]12x^2 - 13x - 7175 = (x-p) (qx + 287)[/tex]:
[tex]-p\cdot287=-7175,\\-p=\frac{-7175}{287},\\p=\fbox{$25$}[/tex].
Now that we found [tex]p[/tex], we must find [tex]q[/tex]. The first term of the quadratic in standard form is formed entirely by [tex]ax\cdot cx[/tex]. Therefore:
[tex]1\cdot q=12, \\q=\fbox{$12$}[/tex].

[tex] \frac{45.4}{30} = \frac{180}{30} = 6[/tex]
We learnt this way in Turkey.
Answer: 6 problems in 4 minutes
Step-by-step explanation: If there are 45 problem and she can do them in 30 minutes, then you divide 45 by 30 to see how many problems she can do in one minute. 45 problems/30 minutes = 1.5 problems per minute. Then, you multiply 1.5 by 4, because you need to see the 4 minute mark, and 1.5 x 4 = 6. So, your answer is 6 problems.

Answer: (x34, y912)
Step-by-step explanation: Because (x34, y912) equals (x34, y912) :)
Answer:
x = 2, y = 6
Step-by-step explanation:
I'm assuming you're finding the pattern and then finding x and y, in which case it would be:
In the first one (x, 3, 4, 5, 6) you can see it goes up by 1 each time so x is just 2.
In the second one (y, 9, 12, 15, 18) it goes up by 3 each time so y = 9-3 = 6.
The choir needs to raise $2,620.00 for a trip to the state competition. They are selling sets of candles for $25.00 per set. They have already raised $1,225.00 from the fundraiser.
The band needs to raise $2,400.00 to pay for a trip to the state capital to participate in a parade. They are selling 3-gallon tubs of caramel popcorn for $18.25 each. They have already raised $1,314.00 from the fundraiser.
Answer:
1086/18.25 = 59.51
60 more tubs of popcorn to reach their target.
Step-by-step explanation:
OK, here we go. Golf Club first
You subtract the total amount they need to raise, by the amount they already have:
2620 - 1225 = $1395.00 to go
Divide that number by the price of golf balls to find out how many more they need:
1395/25 = 55.8
This means that they need to sell at least 56 golf balls to meet the target.
Now to the Percussion Club...
Do the same thing again:
2400 - 1314 = $1086 to go
1086/18.25 = 59.51
So the percussion club needs to sell at lest 60 more tubs of popcorn to reach their target.
