Estimate 81 x 38 (giving brainliest to first person to answer)
Answer: 3200
Step-by-step explanation:
The rounding rule:
The ones digits : + From 1 to 4 we round down
+ From 5 to 9 we round up
So we have 81 rounds to 80 and 38 rounds to 40.
We have 80 * 40 = 3200.
Jana loves to go shopping. Yesterday she borrowed a wad of money from her mother and went to the mall. She began her excursion by spending $18 on a new compact disc. Then she spent half of her remaining money on a new dress. Then she spent $11 taking herself and her friend out to lunch. Then she spent one-third of her remaining money on a book. On her way home she bought gas for $12 and spent one-fourth of her remaining money on a discount CD at the convenience store. Finally, she slipped $2 to her younger brother when she got home and gave her mother back $10 in change. Her mother was furious and demanded an explanation of where the money went.

Write the equation of the parabola in vertex form. The vertex is (−3, −4) and the parabola passes through the point (−1, 0).
Start with vertex form.
y = a(x − h)2 + k
Using the vertex (−3, −4), substitute h = –3 and k = −4.
y = a(x − (−3))2 + (−4)
y = a(x + 3)2 + (−4)
Substitute the included point (−1, 0) into the equation for x and y.
0 = a(−1 + 3)2 − 4
Simplify the equation to solve for a.
0 = a(2)2 − 4
Type your answer and then click or tap Done.
Complete the equation for the parabola in the graph.

. There are seven people in a club: A, B, C, D, E, F, and G. A committee of 3 people is formed. What is the probability that G is on the committee
Step-by-step explanation:
there are 7 over 4 total possibilities to create a group of 3 or if 7.
that is
7! / (4! × (7-4)!) = 7×6×5 / 3×2 = 7×5 = 35
for the probability we need also the number of the desired cases, a the probability is
number of desired cases / number of total cases
the desired cases are all combinations, where G is a part of.
for that we make G a constant, and now we have only 6 variable candidates for the other 2 positions on the committee.
that is 6 over 2 or
6! / (2! × (6-2)!) = 6×5/2 = 3×5 = 15
so, the probability that G is in the committee is

Answer:
a. reflection across line l
b. see attached
c. no
Step-by-step explanation:
a.The easiest transformation to put figure H' back where figure H is will be "reflection across line l". A reflection back across the same line of reflection puts the figure in its original location.
__
b.The attached figure shows the requested translation and labeling. The dim dotted figure is the original translation of H along vector EF. The reflection of that across line l is marked H''' as required.
__
c.No, figures H'' and H''' are not in the same location. One only needs to look at the diagram to see this.
In general the order of translation and reflection makes a difference. This means reflection of H to H', then translation to H'' will have a different result than translation of H to H(shadow), then reflection to H'''.

How many pounds of chocolate that is 45% cocoa should be mixed with 6 pounds of pure cocoa mass to obtain a chocolate that is 78% cocoa? plz help im dying irl
Using a system of equation, the amount in pounds of chocolate required is 4
Let :
Number of pounds of chocolate = cHence, we can create an equation thus :
0.45c + 6(1) = 0.78(6 + c)
0.45c + 6 = 4.68 + 0.78c
Collect like terms
6 - 4.68 = 0.78c - 0.45c
1.32 = 0.33c
Divide both sides by 0.33
c = 1.32 / 0.33
c = 4
Hence, 4 pounds of chocolate is required.

Lin runs 5 laps around a track in 8 minutes. If Lin runs 21 laps at
the same rate, how long does it take her?
a) 13.13 minutes
b) 441 minutes
c) 33,6 minutes
d) 1.6 minutes
Answer:
It will take 25.2 minutes to complete 21 laps.
Step-by-step explanation:
The rate of covering 5 laps is:
v = 6/5
Therefore, the time taken to cover 21 laps is:
t = 21/v
t = 21*6/5
t = 25.2
Hence, it will take 25.2 minutes or 25 minutes 12 seconds for Lin to complete 21 laps.
How do the expressions 7+h2−5 and 10(h+2)−2h compare when h = 9? Drag a symbol into the box to correctly complete the statement. 7+h2−5 Response area 10(h+2)−2h when h = 9.
Answer:
8+h3-4
Step-by-step explanation:
10(h+2)−2h when h = 9.
The relation between the expression at h = 9 will be;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The expressions are,
⇒ 7 + h² - 5
⇒ 10 (h + 2) - 2h
Now,
Solve the expression for h = 9 and find the relation between them as;
Since, The expressions are,
⇒ 7 + h² - 5 ...(i)
⇒ 10 (h + 2) - 2h ...(ii)
Substitute h = 9 in (i), we get;
⇒ 7 + h² - 5 = 7 + 9² - 5
= 7 + 81 - 5
= 83
And, Substitute h = 9 in (ii), we get;
⇒ 10 (h + 2) - 2h = 10 (9 + 2) - 2 x 9
= 10 x 11 - 18
= 110 - 18
= 92
Thus, We get;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h
Therefore, The relation between the expression at h = 9 will be;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h

Step-by-step explanation:
There is a total of 1350 students in the school
One day, 81 of the 1350 students are absent
Work out the percentage of the students who are absent
The percentage of the students who are absent when 81 of the 1350 students are absent is 6%.
What is Percentage?Percentage in simple words can be defined as a part per hundred.
In other words, it is the ratio which can be defined as a fraction of 100. It is usually denoted by the symbol %.
Percentage can also be said as dimensionless number as it does not have any dimensions.
Percentage of a number can be calculated by dividing the number with the whole part and then multiplying by 100.
Total number of students in the school = 1350
Number of students absent = 81
Here we have to calculate the percentage of 81 out of 1350.
Percentage of the students who are absent = [tex]\frac{81}{1350}[/tex] × 100 = 6%
Hence 6% of the students are absent that day.

Hello my name is Galaxy and I will be helping you today! I hope you are having a nice day!
We can solve this in two steps, one being Algebra and the second being Answer/Checking our answer. I'll start off with Algebra.
Algebra
We can start to solve this problem by using Algebra and simplifying it down. We can also use the distributive property to solve the problem by using the proof it shows. The distributive property states that we can multiply whats inside the paranthesis by the number on the outside and get the same answer.
We can prove it by doing this:
[tex]2(1+4)=(2*1)+(2*4)?\\2+8=2+8?\\10=10[/tex]
Now that we have the tools we need to begin solving.
Solving
We can start to solve it by simplifying the equation from its distributive state. We can do that by doing the following:
[tex]-3(x-2)=12\\-3x+6=12\\[/tex]
Now that we've simplified, we can begin solving it.
[tex]-3x+6=12\\-3x=12-6\\-3x=6\\x=6 \div -3\\x=-2[/tex]
We have gotten our answer of x being -2. We can now double check our answers.
[tex]-3(-2-2)=12?\\(-3*-2)+(-3*-2)=12?\\6+6=12?\\12=12[/tex]
Remember that if we multiply two negatives it is a positive!
