Step-by-step explanation:

7d^2
Answer: choice A) [tex]7d^2[/tex]
This is the same as writing 7d^2
==================================================
Explanation:
When we add a number to itself repeatedly, we can use multiplication to shorten things. For example: 3+3+3+3 = 5*3 = 15. We have five copies of '3' being added, which explains the 5 times 3.
Extending this idea leads us to shortening repeated multiplications into exponentiations. In the case of [tex]7*d*d[/tex], we have two copies of 'd' being multiplied. We replace [tex]d*d[/tex] with [tex]d^2[/tex] which is the same as d^2. The ^ symbol means "exponent".
The exponent (2) tells us how many copies of the base (the term d) we multiply out.
Another example would be [tex]d^3 = d*d*d[/tex]
So that's why [tex]7*d*d = 7d^2[/tex]

You work in a grocery store. How many 1/3 pound bags of coffee can you package from a 15 pound box of loose coffee?
Answers
Answer:
45
Step-by-step explanation:
Since each bag is 1/3 of a pound. That means there are 3 bags that make 1 pound. Therefore 15x3 is 45, so you could make 45 bags of coffee

31. Mark carried 3¼ kg of millet, 4¾ kg of sorghum
and 15kg of maize to the market. He sold
2½kg of millet 2¾kg of sorghum and 10kg of
maize. What was the total mass cereals that
remained?
A. 15¼ kg
B. 23kg
C. 8¼kg
D. 7¾kg
what's the solution to solve it?
Answers
Answer:
D
Step-by-step explanation:
(3.25+4.75+15) =23
23- (2.5+2.75+10)
= 7.75
2 1/2 = 5/2 = 10/4
13/4 -10/4 = 3/4 kg of millet left over
Sorghum:
4 3/4 - 2 3/4 = 2 kg of sorghum left over
Maize:
15kg - 10kg = 5kg left over
3/4 + 2 + 5 = 7 3/4 kg total

Changed 19/4 into a mixed number (fraction).
Answers
Answer:
Step-by-step explanation:
Did you mean: Change 19/4 into a mixed number (fraction).
How do you turn 19/4 into a mixed number?
As an improper fraction. (numerator larger than denominator): 19/4 = 19/4
As a mixed number (mixed fraction) (a whole number and a proper fraction, of the same sign): 19/4 = 4 3/4
As a decimal number: 19/4 = 4.75.
As a percentage: 19/4 = 475%
4 and 3/4
16/4 equals 4; then 19/4-16/4 = 3/4, so that's left over.

Answer:
$55.96
Step-by-step explanation:
To find 30% of $79.95, we must multiply 79.95 by .3
We get 23.985, which can be rounded to the nearest 100th to get 23.99
So, 30% of $79.95 is $23.99
Now, we can just subtract to find the sale price.
$79.95 - $23.99 = $55.96

Starting with the fact that angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, use a two column proof to prove that consecutive interior angles a and bare supplementary ( 5 points)
Answers
Answer:
See proof below
Step-by-step explanation:
Two angles that are linear pair sums up to 180°
If angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, then;
1+a = 180....1
2+b= 180....2
Taking the sum of both equations
1+2+a+b = 360°... 3
Note that the sum of the adjacent angles will also be 180° since they also lie on the same straight line, hence;
1+2 = 180°...4.
Substitute 4 into 3
From 3;
1+2+a+b = 360°
(1+2)+(a+b) = 360°
180+(a+b) = 360
a+b = 360-180
a+b = 180
Since the sum of a and b is 180°, this shows that angles are supplementary since the sum of 2 supplementary angles is also 180°
Hence this shows that the consecutive interior angles a and bare supplementary.
Answer:
180-35=145 Degrees
Step-by-step explanation:
TBH I may not have a complete understanding; but what I do know is a straight line (or angel if you so chose) is equal to 180 degrees (NOTE: supplementary- angels are when 2 angels that are added up to 180 degrees) and on my part of the question is: "Starting with the fact that angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, use a two column proof that consecutive interior angles a and b are supplementary".
Now in my whole complete course its asking a bout a ski slope and it gives me the 35 degree angle and we need to figure out the missing angle, we have the same picture as listed above.... knowing that straight lines are 180 degrees I subtracted 180-35 and I got 145 degrees now either i'm right or i'm missing som I did in a few years back but most of my information is basically backed up by some understanding I do know
