Answer:

I think it's 6 but im not sure

hope this helps

have a good day :)

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

add 16 to zero

4x2=16

Divide 4x by 2 and 16 by two

4x=8

divide 8 by 4

x=2

Answer:

x = ± 2

Step-by-step explanation:

Given

4x² - 16 = 0 ( add 16 to both sides )

4x² = 16 ( divide both sides by 4 )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

solutions are x = - 2, x = 2

Answer:

11. parallelogram, rectangle

12. parallelogram, rhombus

13. parallelogram, square

For parallelogram:

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

for rectangle:

A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon and hexagon), and 4-gon (in analogy to n-gons for arbitrary values of n).

for rhombus:

In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond.

for Square:

·There are four methods that you can use to prove that a quadrilateral is a square. In the last three of these methods, you first have to prove (or be given) that the quadrilateral is a rectangle, rhombus, or both:

·If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).

·If two consecutive sides of a rectangle are congruent, then it’s a square (neither the reverse of the definition nor the converse of a property).

·If a rhombus contains a right angle, then it’s a square (neither the reverse of the definition nor the converse of a property).

·If a quadrilateral is both a rectangle and a rhombus, then it’s a square (neither the reverse of the definition nor the converse of a property).

Answer:

Alan can buy the bike for $109.85

Step-by-step explanation:

Start with 100% and subtract the 35% discount.  This results in 65%.  The bike sells for 65% of $169, which is calculated as follows:

0.65($169) = $109.85

Alan can buy the bike for $109.85 under the terms of this sale.

Answer:

answer: C. 5 out of 10

Step-by-step explanation:

Theoretical probability is what is expected to happen sense a coin has 2 sides theres a 1/2 chance at getting heads so 5 out of 10 is the theoretical probability because 5 is half of 10 hope this helps!

Answer:

Step-by-step explanation:

on the first one we see that they are outer angles and they are also congruent making the missing angle the same as 66

for the second one if we turn the graph around making the lines how a H shape we see the missing angle and the given angle are in the same line, and we know a straight line makes it 180, so we need to find what the other angle is using the given angle so we subtract from 180, 180-80 = 100

so the missing angle is 100 making it congruent to the other missing angle that was with the 80

for the last one by now we should know what vertical angles are, they are directly across from each other, and we see that they arent really like in the same part of the line, but we know that the one congruent to the 128 is the outer right angle, making the missing angle congruent because they are vertical angles making the missing angle 128 too

(did that make sense?)

Answer:

33.33%

Step-by-step explanation:

Answer:

33.3333%

explaination

When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form. Now we can see that our fraction is 33.333333333333/100, which means that 25/75 as a percentage is 33.3333%

Answer:

x<7

Step-by-step explanation:

Answer: x=7, x<18, true

Step-by-step explanation: -10 becomes +10, then you add 10+18. 4x<28 is now the expressio. 28/4=7, x=7 and x or 7<28. This equation is true.

Answer:

7.85

Step-by-step explanation:

firstly convert the 45 deg into radians

which is 0.785398 rads multiply it by ten ..

using the formula s=r∅

Answer:

Correct Answer Is 7.85

Step-by-step explanation:

Since 45 degrees is 1/8th of a circle Then you would find the circumference divided by 8.

10= Radius Then Circumference= 62.83

(Divide Circumference by 8) = 7.85 (Answer)

Answer:

Step-by-step explanation:

Answer:

The correct option is B: the surface area of the second box is 4 times larger.

Step-by-step explanation:

The surface area of the first box is given by:

[tex] SA_{1} = 2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1} [/tex]

Where:

l₁: is the length = 8 in

h₁: is the height = 15 in

w₁: is the width = 6 in

[tex] SA_{1} = 2*8*15 + 2*6*15 + 2*8*6 = 516 in^{2} [/tex]

The second box's dimensions are:

l₂ = 2*8 in = 16 in

h₂ = 2*15 in = 30 in

w₂ = 2*6 in = 12 in

Hence, the surface area of the second box is:

[tex]SA_{2} = 2*2l_{1}*2h_{1} + 2*2w_{1}*2h_{1} + 2*2l_{1}*2w_{1} = 4(2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1}) = 4*SA_{1} = 4*516 in^{2} = 2064 in^{2}[/tex]

Therefore, the correct option is B: the surface area of the second box is 4 times larger.

I hope it helps you!                              

Answer:

15 marbles in a jar.

Step-by-step explanation:

[tex]\frac{y}{3000} :\frac{1}{200}[/tex]

y · 200 = 3000 · 1

200y = 3000

200y ÷ 200 = 3000 ÷ 200

y = 15

Answer:

15 marbles in each jar don't know if that's what you're asking.

Step-by-step explanation:

but thx for points

Answer:

a = length

b = height(width)

a=3b

2(a+b)=120

2(b+3b)=2(4b)=8b

8b=120

b=15

a=45

length is 45 feet

width is 15 feet

Answer:

x = 41

Step-by-step explanation:

All triangle angles add up to 180 so:

x + 90 + 49 = 180

x + 139 = 180

x = 180 - 139

x = 41
