Answer:
The first one $1.42
Step-by-step explanation:
1.42x5=7.1 (cost of all envelopes)
12-7.1=4.9
4.9/14=0.35 (one postcard)
10 postcards= 3.5
1.42x15=21.3 (cost of all envelopes)
3.5+21.3=$24.80

Given
AB: AC = 1:2
AB= 3x-4
AC= 2x + 12
show that
AC: BC = 2:3
BС= 7X-2
Answer:
Step-by-step explanation:
AB/AC =1/2
(3x-4)/(2x+12)=1/2
2(3x-4) = 1(2x+12)
6x-8=2x+12
4x=20
X=5
AC/BC =3x-4/7x-2=22/33=2/3
AB/AC=3x-4/7x-2=22/33=2/3
AB/AC=3x-4/2x+12
6x-8=2x+12
You would get 4/5 still trying to work out the last mark
Step-by-step explanation:
First find x:
AB:AC=1:2
2(3x-4)=2x+12
6x-8=2x+12
4x-8=12
4x=20
x=5
Substitute:
AC=2x+12
=(2x5)+12
=10+12
=22
BC=7x-2
=(7x5)-2
=35-2
=33
22/33=2/3
Therefore AC:BC = 2:3
At 8:00, the temperature was 15 degrees Celsius (°C). Three hours later, the temperature was -15°C. By how many degrees Celsius did the temperature change?
Answer:

The designers of drink cartons must consider the length of the straw required so that it will reach the bottom
of the carton. We will make the following assumptions:
-the straw must stick out of the carton by an additional 1.5 cm
-the hole is at one vertex of the carton
-the straw must be able to reach into the diagonally opposite corner of the base of the carton
use the formula a^2+b^2+c^2=d^2
CHECK IMAGE FOR VISUAL REPRESENTATION OF THE CARTON
Answer:
The length of the straw is 13.53 cm
Step-by-step explanation:
Rectangular Prism
A rectangular prism or cuboid is a box-shaped object. It has six flat faces and all angles are right angles. And all of its faces are rectangles.
If the straw must reach into the diagonally opposite corners of the base of the carton, then its minimum length is calculated by:
[tex]d^2= a^2+b^2+c^2[/tex]
Where a,b, and c are the dimensions of the cuboid. The image shows the dimensions of the drink carton: a=6 cm, b=10 cm, c=4 cm (order is not important), thus:
[tex]d^2= 6^2+10^2+4^2=36+100+16=152[/tex]
[tex]d=\sqrt{152}[/tex]
d= 12.33 cm
The straw must stick out of the carton by an additional 1.5 cm, thus the total length of the straw is: 12.33 + 1.5 = 13.53 cm

please help what is the value of u
Answer:
34
Step-by-step explanation:
It is an isosceles triangle.
112 + u + u =180 {Angle sum property}
112 + 2u = 180
2u = 180 - 112
2u = 68
u = 68/2
u = 34
A department store sells a pair of shoes with an 87% markup. If the store sells the shoes for $193.21 then what is their non-markup price?
Step-by-step explanation:
87% + 100% = 187%
187% of original price = $193.21
100% of original price = $193.21 * (100/187) = $103.32.
The non-markup price is $103.32.
Answer:
87% + 100% = 187%
187% of original price = $193.21
100% of original price = $193.21 * (100/187) = $103.32.
The non-markup price is $103.32.

factor with distributive property (no variables) 55 + 35
55 + 35 Factorized ↓
5(11 + 7)
I hope this helps u
God bless
Answer
5(11+7)
1. Find the greatest common factor of 55 and 35.
The greatest common factor of 55 and 35 is 5.
2. Divide each number (in the expression) by the common factor
55/5=11
35/5=7
3. Write the factorized expression
So you multiply 5 times 11 and 5 times 7.
So when distributing, you would multiply the number outside of the parentheses by each of the numbers in the parentheses.
The number outside is 5 and the numbers inside are 11 and 7.
So the expression is 5(11+7)
5*11=55
5*7=35
4. Check to see if you get the same answer (optional)
55+35=90
5(11+7)=5(18)=90
4x+8 =20

Determine which number would satisfy the inequality 3y-8>22. Choose all that apply.
A. 13
B. 0
C. -5
D. 10
E. 11
Answer:
my best guest would be only 10
Step-by-step explanation:
There are 13, and 11 are would satisfy the given inequality 3y - 8 > 22. The correct answer would be options (A), and (E).
What is inequality?An Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
The inequality is given in the question, as follows:
3y - 8 > 22
We have to determine which number would satisfy the inequality.
As per the question, we have
⇒ 3y - 8 > 22
Add 8 both sides of the above inequality,
⇒ 3y - 8 + 8 > 22 + 8
⇒ 3y > 30
Divided 3 into both sides of the inequality, we get
⇒ y > 30/3
⇒ y > 10
So, we can conclude that 13, and 11 would satisfy the inequality.
Hence, the correct answer would be options (A), and (E).

Answer:
-7/2
Step-by-step explanation:
Use distributive property: a(b +c) = a*b +a*c
-2(y-1) = 9
y*(-2) - 1*(-2) = 9
-2y + 2 = 9 {Subtract 2 from each side}
-2y = 9 - 2
-2y = 7 {Divide each side by -2}
y = 7/-2

an elevator began at an elevation of 85.5 feet and ascended at a rate of 2.75 feet per second. what was the elevation of the elevator after 8 seconds?
Answer:
107.5
Step-by-step explanation:
8 × 2.75ft = 22ft
22ft + 85.5ft = 107.5ft
Answer:
107.1
Step-by-step explanation:
the elevator is at 85.5 feet.
if the ascending (going up) rate is 2.75 and you want to know how far in 8 seconds, it's an easy process.
1. find the direction your going (up or down)
2. how far? (what rate for this one)
3. multiply said problem (2.75 x 8)
4. get your answer (21.6 ft per 8 seconds)
5. add or subtract to the height you are at now (85.5 ft)
6. you now have your answer! (107.1 ft in the air)
How much closer to the sun is one planet than the other?
Answer:
C. 7.79 x 10^8
Step-by-step explanation:
Your Equation: (eight-point-one multiplied by ten to the eighth power) subtracted by (nine-point-one multiplied by ten to the seventh power)
so first we find out how much are in the parentheses :D
(8.7 x 10^8) = 870,000,000
(9.1 x 10^7) = 91,000,000
now you subtract 870,000,000 by 91,000,000.
870,000,000
- 91,000,000
---------------------
779,000,000
converted back to standard form...

The slope of the line below is 2. Which of the following is the point-slope form of the line?
The correct point-slope form of the line is A. y + 1 = 2(x - 1).
The point-slope form of a linear equation is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.
Given that the slope of the line is 2 and the point on the line is (1, -1), we can substitute these values into the point-slope form to find the correct equation.
Using the point-slope form, we have:
y - (-1) = 2(x - 1)
Simplifying the equation, we get:
y + 1 = 2(x - 1)
Now we compare this equation to the answer choices:
A. y + 1 = 2(x - 1)
B. y - 1 = -2(x + 1)
C. y + 1 = -2(x - 1)
D. y - 1 = 2(x + 1)
Comparing the equation y + 1 = 2(x - 1) to the given point-slope form, we see that they match.
In this equation, the point (1, -1) lies on the line, and the slope of the line is 2. The equation represents a line with a slope of 2 that passes through the point (1, -1).

Step-by-step explanation:
It is a right triangle so you can use the pythagoreum theorem.
a(a) + b(b) = c(c)
a and b: legs
c: hypostenuse
9 and 7 are legs
the unknown is the hypostenuse
9(9) + 7(7) = c(c)
81 + 49 = c(c)
130 = c(c)
square root of 130 is 11.4017543
c(c) = 130
c = 11.4017543
