Answer:
What do you need though...
A basic rundown since I have no clue what you need help with
Parallelograms
(4 sided shapes that always adds up to 360 degrees if you add all the angles inside with opposite sides parallel)
Squares, rectangles (most common)
Triangles
3 sided figures with all the interior angles being added up equals to 180 degrees. The 3 sides of a triangle can be found with a^2+b^2=c^2.
The properties are 2 legs and 1 hypotenuse. To determine if its a triangle, if the 2 legs added up (two of the shortest sides) they must be greater then the hypotnuse (greatest side).
THese are the two of the most common shapes if you need an huything else just lemme know in the comments.

16 emails to 6 text messages- 10 emails to 4 text messages proportional or not
Given:
16 emails to 6 text messages- 10 emails to 4 text messages
To find:
Whether 16 emails to 6 text messages- 10 emails to 4 text messages proportional or not.
Solution:
Check the ratio of emails to text. If the ratios are equal then the relation is proportional.
16 emails to 6 text messages.
[tex]\dfrac{Emails}{Text}=\dfrac{16}{6}[/tex]
[tex]\dfrac{Emails}{Text}=\dfrac{8}{3}[/tex]
[tex]\dfrac{Emails}{Text}=8:3[/tex]
10 emails to 4 text messages.
[tex]\dfrac{Emails}{Text}=\dfrac{10}{4}[/tex]
[tex]\dfrac{Emails}{Text}=\dfrac{5}{2}[/tex]
[tex]\dfrac{Emails}{Text}=5:2[/tex]
Since [tex]\dfrac{8}{3}\neq \dfrac{5}{2}[/tex] or [tex]8:3\neq 5:2[/tex], therefore, it is not proportional.

From a point 80 m from the base of a tower, the angle of elevation to the top of the tower is 28°. How tall is
the tower (remember: 3 decimal places)?
The height of the tower is [A] m.
Answer:
42.537 m
Step-by-step explanation:
Let x = height of tower
tan 28 = x/80
x = 80 tan 28
x = 42.537 m

[tex] \triangle TFG\sim \triangle TUV... (given) [/tex]
[tex] \therefore \frac{FG}{UV}=\frac{TG}{TV} ... (csst) [/tex]
[tex] \therefore \frac{45}{63}=\frac{10x+5}{49} [/tex]
[tex] \therefore \frac{5}{7}=\frac{10x+5}{49} [/tex]
[tex] \therefore 10x+5= \frac{5\times 49}{7} [/tex]
[tex] \therefore 10x+5=5\times 7 [/tex]
[tex] \therefore 10x+5=35 [/tex]
[tex] \therefore 10x=35-5 [/tex]
[tex] \therefore 10x=30 [/tex]
[tex] \therefore x=\frac{30}{10} [/tex]

Answer:
A
Step-by-step explanation:
since the shaded area is before x=-3 and x=-3 is a dashed line, x<-3 is the answer for x. That knocks out half the answers. the slope intercept form for the other line is y=-x-1. The answer with the slope as y would be the answer for the second half. A has both answers correct. (sorry for bad explaination, I am not a native speaker)

What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
We are given the equation as;
5x-2.5=17.5
Solving for x;
5x=17.5+2.5
5x=20
x=20/5
x=4

Kenise will begin college as a freshman next fall and has received a 10-year $5,500 Federal Direct Unsubsidized Loan with an interest rate of 6.8%. She will be required to begin making payments six months after graduation. How much interest will accrue while she is still in school and over the six-month grace period? Please round to the nearest dollar. Do not include the dollar sign.
Answer: $3,927
Step-by-step explanation:
The interest will accrue as a simple interest rate for 10 years and then the grace period of six months.
The total time is therefore: 10.5 years.
Interest for those 10.5 years is:
= Loan amount * No. of periods * interest rate
= 5,500 * 10.5 * 6.8%
= $3,927

Answer:
A
Step-by-step explanation:
For the equation to be true, any number that would be multiplied by 7/5 should give us a number that is less than 7/5.
This means any number we are going to use to multiply 7/5 must not be less than 1.
²/3 is less than 1.
Let's multiply and see:
⁷/5 × ⅔ < ⁷/5
14/15 < ⁷/5 (this is true because ⁷/5 is greater than 14/15)
Therefore, the answer is A.

We can find the slope by using 2 coordinates that are on a line.
We can choose any of the coordinates from this table. I'm gonna use (0, 4) and (2, 5)
The formula for find the slope is the rise over the run or
y1 - y2 / x1 - x2
4 - 5 / 0 - 5
-1 / -5
1/5
The slope is 1/5
