B. 3 (x + 15) = 180
C. 3 (x + 15) = 60
D. x + 15 = 60
E. 3x = 135

Answer:

Your answer would be A. RSTU results from a translation of ABCD is not true.

Step-by-step explanation:

when you look at the images, it states the figure RSTU backwards, meaning, that it had to be reflected over the y-axis at some point, not a translation because a translation could not reflect a figure like a reflection can.

Answer:

a=3

Step-by-step explanation:

[tex]2a + 6 = 12[/tex]

[tex]2a+6-6=12-6[/tex] ( Subtract 6 from both sides)

[tex]2a=6[/tex] ( Simplify)

[tex]\cfrac{2a}{2}=\cfrac{6}{2}[/tex] (Divide both sides by 2)

[tex]a=3[/tex]

Answer:

2a+6=12

2a=12-6

a=6/2

a=3

Answer:

1.I think the dot plot was the right decision because we are trying to go over specific data.For instance bar graphs are good if you are trying to get data on things that are in ranges like 1-3 and 4-6 but when you have things like this where he is trying to show each value its better to use a dot plot

2. 16 students are in this class (you can just count the dots to get this answer)

3. the class is a adult swim class-yes,this class ranges between 18 year olds to 32 year olds which are all legally adults

Half the students are between 2 and 3 years old-no,the minimum or youngest age that this set has is 18 years old which is still alot of a higher value than 2 or 3

Answer:

0.66

Step-by-step explanation:

4.91 x 10^2

Calculate 10 to the power of 2 and get 100.

4.91×100

Multiply 4.91 and 100 to get 491.

491

7.47×10^2

Calculate 10 to the power of 2 and get 100.

7.47×100

Multiply 7.47 and 100 to get 747.

747

491 divided by 747=0.65729585006693440428380187416332

0.65729585006693440428380187416332 is rounded to 0.66

Answer:

1. 17/40, 0.425, 42.5%

2. 7/8, .875, 87.5%

Step-by-step explanation:

Add all of our balloons popped, which is 40. striped balloons popped is 17, so 17/40. which is 0.425 and 42.5%

for polka dots, it would be 7/8. 35/40 simplest form is 7/8 then we get .875, which is 87.5%

Answer:

The answer to this question would be c

Answer:

Assuming the area is made up of a square and a semicircle.

Perimeter

The side length of the square = 18 ft

We can see 3 full side lengths plus one side length from which we need to subtract 12 ft (see attached diagram).

⇒ perimeter of the square = (3 x 18) + (18 - 12)

                                                          = 54 + 6

                                                          = 60 ft

Circumference of a circle = [tex]\pi[/tex]d (where d is the diameter)

⇒ arc length of the semicircle = 1/2 circumference

                                                  = 1/2 · [tex]\pi[/tex] · 12

                                                  = 6[tex]\pi[/tex] ft

Total perimeter = 60 + 6[tex]\pi[/tex] = 78.8 ft (nearest tenth)

Area

Area of a square = s² (where s is the side length)

⇒ area of square = 18²

                             = 324 ft²

Diameter = 2r  ⇒  r = 1/2 diameter

Area of a circle = [tex]\pi[/tex]r²  (where r is the radius)

⇒ area of the semicircle = 1/2 · [tex]\pi[/tex] · 6²

                                         = 18[tex]\pi[/tex] ft²

Total area = 324 + 18[tex]\pi[/tex] = 380.5 ft² (nearest tenth)

Answer:

48 square units

Step-by-step explanation:

Area = length x width

        = 8 x 6

        = 48

Answer:

588

Step-by-step explanation:

8 x 3.5 = 28
6 x 3.5 = 21

Formula = Length x Height = Area

28 x 21 = 588

Answer:

10) acute triangle

13) right triangle

Step-by-step explanation:

all triangles have angles that add up to 180 degrees

find the third angle of the triangle by subtracting the known angles from 180

180-75-78=27

acute triangles have no angles that surpass 90 degrees which fits that triangle's description

180-54-36=90

since one angle is 90 degrees, it is a right triangle

Answer:

[tex]\huge\boxed{\bf\:10) \: Acute \: angled \: triangle}[/tex]

[tex]\huge\boxed{\bf\:11) \: Right \: angled \: triangle}[/tex]

Step-by-step explanation:

▪︎ Question 10 :

We need to find the missing angle at first. Take it as 'x' .

We know through the angle sum property of a triangle that the total sum of all the angles in a triangle will sum up to 180°. Hence,

75° + 78° + x° = 180°

153° + x° = 180°

x° = 180° - 153°

x° = 27°

Then, since all the angles are less than 90°, we can say that the triangle is an acute angled triangle.

[tex]\rule{150pt}{2pt}[/tex]

▪︎ Question 11 :

Just like the above question, we need to find the missing angle at first. Take it as 'y' .

The total sum of all the angles in a triangle will sum up to 180° (angle sum property of triangles). Hence,

36° + 54° + y° = 180°

90° + y° = 180°

y° = 180° - 90°

y° = 90°

Since, one angle is equal to 90°, the given triangle is a right angled triangle.

Answer: Lets say BC and EF = Xcm. AC is clearly longer than BC so its greater than Xcm. If AC is longer than Xcm, and EF is Xcm, then AC is no doubt longer than EF.

Step-by-step explanation:

Answer: A is farther away from C

Step-by-step explanation:

If BC = EF, then AC has to be greater than EF. This is because A is farther away from B from C

[tex]\dfrac 34(5a-16) - \dfrac 13(6a-3)\\\\=\dfrac{15a}4 - \dfrac{48}4 - 2a + 1\\\\=\dfrac{15a}4 -12-2a+1\\\\=\dfrac{15a}4 -2a -11\\\\=\dfrac{15a-8a-44}{4}\\\\=\dfrac{7a-44}4[/tex]

Answer:

1.75a - 11

Step-by-step explanation:

Remember your order of operations, first you want to start inside the parantheses. Nothing can be simplified there so move on to multiplication.

Distribute (mutiply) ¾ with (5a - 16) as well as -⅓ with (6a - 3) to get

3.75a - 12 - 2a + 1

Combine like terms, so 3.75 with -2a as well as -12 with 1.

1.75a - 11

Which you could also write as

⁷⁄₄a - 11 or 1¾a - 11

Answer:

The volume is 160

Step-by-step explanation:

Explanation: To find the volume of the rectangular prism you need to multiply 8x20. The reason is because there are 20 cubes in each row (i'm sorry if i'm not good at explaining math very well). The way I found the volume was to count the amount of cubes on the side and multiply it by how many rows there were on top. So that brings me to 160. The product of 8x20. (I hope this helps, math isn't my best subject)

Answer:

V = 160 cubic inches

Given that,

Length, width and height of prism are 8 inches, 4 inches and 5 inches

The formula for the volume of a rectangular prism is given by :

So, the volume of the prism is 160 cubic inches.

According to the question,

The ratio of almond flour to coconut flour is 7:38

so,

the volume of the almond flour used in a day ,in terms of cups would be

[tex] \rightarrow \frac{180 \times 7 }{7 + 38} \\ [/tex]

[tex] \rightarrow \frac{1,260 }{45} \\ [/tex]

[tex] \rightarrow28[/tex]

hence ,28 cups of almond flour would be required to meet the need to prepare the mixture for a day.

______________________________________

volume of coconut flour required in a day ,in terms of no. of cups would be
