Can someone help me out with this my grade are bad

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:

555.1 ft

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:

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

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:

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)

Step-by-step explanation:

Answer:

[tex]Pr = 0.55[/tex]

Step-by-step explanation:

Given

Represent the dataset with the following frequency table

[tex]\begin{array}{cc}{Item} & {Frequency} & {Fiction\ Book} &{11} & {Non\ Fiction\ Book} & {5} & {DVD} & {3} & {Audiobook} & {1} \ \end{array}[/tex]

Required

Probability that the next checkout will be fiction

From the above frequency table, we have:

[tex]Fiction\ Book = 11[/tex]

[tex]n =20[/tex] --- total

So, the probability that the next checkout item is a fiction book is:

[tex]Pr = \frac{Fiction\ Book}{n}[/tex]

[tex]Pr = \frac{11}{20}[/tex]

[tex]Pr = 0.55[/tex]

Answer:

D. is the answer

Step-by-step explanation:

the side lengths always have to be equal so 6+8 = 10    and 10 is equal to 10

that means it makes a right triangle

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:

The standard form of a linear equation is Ax+By=CAx+By=C.

5x+3y=2

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:

602.88cm²

Step-by-step explanation:

Find the image of the cylinder attached

Surface area of a cylinder = A=2πrh+2πr²

r is the radius = 4cm

Height h = 20cm

Substitute

A = 2πr(r+h)

A = 2π(4)(4+20)

A = 8π(24)

A = 192π

A = 192(3.14)

A = 602.88cm²

Hence the surface area of the cylinder is 602.88cm²

Answer:

[tex]\frac{1}{81}[/tex]

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] × [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{3}[/tex]

1 × 1 × 1 × 1 = 1

3 × 3 × 3 × 3 = 81

[tex]\frac{1}{81}[/tex]

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.
