5 (a+1)=
Can someone give me the steps?
Answer:
5a + 5
Step-by-step explanation:
5(a+1)=
5xa + 5x1=
5a + 5
Answer:
5 (a + 1) = 5a + 5
Step-by-step explanation:
You only have to open the parenthesis to simplify this expression.
5 (a + 1)
You multiply 5 by a, and you get 5a.
You also multiply 5 by 1, and you get 5.
5a + 5
So, 5 (a + 1) = 5a + 5.
Find the measure of the missing angles.
Answer:
angles b and c should be 153° each.
Step-by-step explanation:
We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°

which binomial is a factor of 8x^2y^3-18y
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
[tex]8x^2y^3-18y[/tex]
Apply exponent rule: [tex]a^{b+c}=a^ba^c[/tex]
[tex]8x^2y^3-18y=8yy^2-18y[/tex] ∵ [tex]x^2y^3=yy^2[/tex]
[tex]=4\cdot \:2yy^2+9\cdot \:2y[/tex]
Factor out common term 2y
[tex]=2y\left(4x^2y^2-9\right)[/tex]
We know that the Binomial is an expression that consists of two terms. Thus,
(4x²y²- 9) represents the binomial factor of [tex]8x^2y^3-18y[/tex]
We can further simplify by Factoring 4x²y² - 9: (2xy + 3) (2xy - 3)
[tex]=2y\left(2xy+3\right)\left(2xy-3\right)[/tex]
Here:
(2xy + 3) and (2xy -3) are the binomial factors of [tex]8x^2y^3-18y[/tex] as each of them consists of two terms.

An element with mass 970 grams decays by 27.7% per minute. How much of the element is remaining after 13 minutes, to the nearest 10th of a gram?
9 is 150% of what number
Answer:
6
Step-by-step explanation:
Let the number be x then
150% of x = 9
150 / 100 * x = 9
150 x = 900
x = 900/ 150
x = 6
Hope it will help :)❤
Answer:
6
Step-by-step explanation:
150% of x = 9
150 / 100 * x = 9
150 x = 900
x = 900/ 150
x = 6

A man drove 250 miles in 2.5 hours. If the posted speed limit was 75 mph the entire way how many miles per hour over the speed limit was he going?
A. 10 mph
B. 50 mph
C. 25 mph
D. 78 mph
Answer:
C. 25 mph
Step-by-step explanation:
First, find his speed in miles per hour:
250/2.5
= 100
This means he was going 100 mph
To find how much he was going over, subtract 75 from this
100 - 75
= 25
So, he was going 25 mph over the speed limit
The correct answer is C, 25 mph

Customers buy 10 units of regular beer and 16 units of light beer monthly. The brewery decides to produce extra beer, beyond that needed to satisfy the customers. The cost per unit of regular beer is $26,000 and the cost per unit of light beer is $47,000. Every unit of regular beer brings in $250,000 in revenue, while every unit of light beer brings in $500,000 in revenue. The brewery wants at least $15,000,000 in revenue. At least 23 additional units of beer can be sold. Complete parts (a) and (b).

what is the answer to the question
Answer:
D. 22 square feet
Step-by-step explanation:
From what I can see of the measurements, I think the answer is 22 square feet. Divide the L into two rectangles: 8x2 for the top one gives you 16 square feet; 3x2 for the bottom one give you 6 square feet. Add 16 and 6 for the area of the entire shape. You get 22 square feet.

Solve for n: 21 K - 3n + 9 p is greater than 3 p + 12
Answer:
n > p + 1 + 7k
Step-by-step explanation:
21k - 3n + 9 > 3p + 12
21k - 3n > 3p + 12 - 9
3n > 3p + 3
3n > 3p + 3 + 21k
n > (3p + 3 + 21k)/3
n > p + 1 + 7k
Triangle A is a scaled version of triangle B. The dimensions of triangle B are twice the dimensions of triangle A. The area of
triangle B is 144 sq cm.
What is the area of triangle A?
Answer:
576 sq cm
Step-by-step explanation:
For example imagine a rectangle, the area of which is width * height = area
If you multiply the dimensions by 2 you multiply the width AND the height which is 2 * width * 2 * height = 4 * width * height
This is true for all scalings, if you times the dimensions by n, you times the area by n^2
144 * 2^2 = 576
