A scale drawing with a 1: 0,8 scale will have sides that measure 2.24, 1.6, and 3.2.
What is a scale drawing?A scale drawing refers to a drawing that has been made bigger or smaller but preserves the proportions of a drawing.
How to make the scale drawing of the sign?The first step is to decide the scale. In this case, the best scale is 1:0.8, which means the new drawing is 0.2 smaller. This scale is ideal because this sign is slightly bigger than regular signs.
Draw the sign by multiplying each side by the scale (0,8).

The area of a rectangle is represented by3x^{2}-10x-8. Which expression can also be used to represent the area of the same rectangle? explain your thinking.
1) (3x + 2)(x − 4)
2) (3x + 2)(x + 4)
3) (3x + 4)(x − 2)
4) (3x − 4)(x + 2)
just factorise it so the answer will be (3x+2)(x-4)
Habiendo salido el 84% de los alumnos de un colegio, permanecen en el mismo 20 alumnos. ¿Cuántos alumnos salieron del colegio?
Answer:
105 students
Step-by-step explanation:
The computation of the number of students left the school is given below:
Let us assume the total students be x and 100%
Left percentage = 84%
Remaining percentage = 100% - 84% = 16%
Now according to the question
16% of x = 20
0.16x = 20
x = 20 ÷ 0.16
x = 125
Total students 125
Those who left is
= 84% of 125
= 105 students

Answer:
30 games
Step-by-step explanation:
if they won 12 games which is 40% of their total games played 100% is the number of games played .form an equation...
if 12=40
x=100 cross multiply 12 and 100 then divide by 40 to get x
12×100=1200÷40=30.

Evaluate: 19 - 3k] = 3
Answer:
k = [tex]5\frac{1}{3} ,7\frac{1}{3}[/tex]
Step-by-step explanation:
|19 - 3k| = 3
-3k = 3 - 19
-3k = -16
k = 16/3
k = 5 1/3
-19 + 3k = 3
3k = 3 + 19
3k = 22
k = 22/3
k = 7 1/3

What is the next term of the geometric sequence 5, 20,80
Answer:
a₄ = 320
Step-by-step explanation:
To obtain a term in a geometric sequence , multiply the previous term by the common ratio r
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{20}{5}[/tex] = 4 , then
a₄ = 4 × a₃ = 4 × 80 = 320

Use the distance formula to find the distance between each PowerPoint round to the nearest 10th if necessary
Answer:
Step-by-step explanation:
Distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
a). A(-6, -4), B(-3, -1)
Distance between A and B = [tex]\sqrt{(-6+3)^2+(-4+1)^2}[/tex]
= [tex]\sqrt{9+9}[/tex]
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D = [tex]\sqrt{(3.5+4)^2+(1-2.5)^2}[/tex]
= [tex]\sqrt{58.5}[/tex]
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance = [tex]\sqrt{(5+5)^2+(-5-5)^2}[/tex]
= [tex]\sqrt{200}[/tex]
= 10√2
= 14.14
≈ 14.1 units

find the angle of 1 and 3
Answer:
Angle of 1 and 3 as 90*
Step-by-step explanation:
This is because all angles are the same meaning all angles are 90*. Even 1 and 3. Brainiest and a thank you?!
Answer:
We really aren't provided with enough information to give you the answer. I'll explain how to find them, but you should comment on my response and tell be if it gives you any values at all to work with.
So, ∠1 and ∠3 are vertical angles, which means they are equal to each other.
Along with that, ∠2 and ∠4 and also vertical angles, so they're equal to each other as well.
Now we have the information:
∠1 = ∠3
and
∠2 = ∠4
__________________________________________________________
Given that both of the two lines are intersecting, each angle has two angles that it is supplementary to.
Supplementary angle are angles that when added together equal exactly 180°.
A perfectly straight line's angle it 180°.
Using this knowledge, you can find that ∠1 is supplementary to ∠2, ∠2 is supplementary to ∠3, ∠3 is supplementary to ∠4, and ∠4 is supplementary to ∠1.
If that's still confusing, here's it explained simpler:
∠1 + ∠2 = 180°
∠2 + ∠3 = 180°
∠3 + ∠4 = 180°
∠4 + ∠1 = 180°
__________________________________________________________
But still - you haven't given us the information to find these values. Are you given even one angle measurement to work with?? If so, comment it here and I'll work it out for you.

A store sold 655 bicycles last year. This year the store sold 582 bicycles. What is the percent of change in the number of bicycles sold from last year to this year? Round to the nearest percent
Answer:
12.5%
Step-by-step explanation:
Given data
Number of bicycles sold last year= 655
Number of bicycles sold this year= 582
%percent change= Iniitial -FInal/initial *100
%percent change= 655-582/582*100
%percent change= 73/582 *100
%percent change=0.125 *100
%percent change=12.5%
Hence the percent change is 12.5%

Answer:
y=2/5x+8/5
Step-by-step explanation:
so say you plot a graph of rain against the hours the gradient would be the rate of change and the information given as your points and the gradient
now to get an equation of a straight line use one of your points eg(1,2) and the gradient or rate of change mine was 0.4

The area of a rectangle is 38.5 square inches. The base of the rectangle is 4 inches. What is the height of rectangle?
Pls help me on this one. PLSSS :(
Answer:
The answer is 9.625
Step-by-step explanation:
So what you have is the area and the base of the rectangle. To find the height, just divide 4 into 38.5
38.5 / 4 = 9.625
To double check just multiple 9.625 by 4
9.625 x 4 = 38.5
Hope this helps
