Answer: 2 4/5 +(3/5 x 1/3)

Order of operation 3/5 x 1/3 =3/15

2 4/5 + 3/15 need common denominator

2 12/15 + 3/15 If you multiply 4/5 by 3/3

you get 12/15

12 +3=15.

The denominator stays the same so you get 15/15 or 1 whole and you already have 2 wholes so 2+1= 3 so the answer will be 3

What is the area of this compound shape?

Answers

Answer:

139.36

Step-by-step explanation:

first you do 8*8 because that would be the area of the square part

8*8=64

then find the area of the semicircle

first the Radis of it is 4 because 8/2=4

A=3.14R^2/2

3.14*4^2/2

3.14*16/2

50.24/2

25.12

now because there are 3 of the semicircles you do

25.12*3

A business made $1.5 million in sales this year, and estimates a 7% increase in sales for the coming year.

If the company allocates 10% of expected sales for promotional activities, how much would be allocated (set aside) for next year's promotion (advertising)?

Answers

Answer:

$160,500

Step-by-step explanation:

First, find the coming years sales

7% of 1,500,000 is 105000

105,000+1,500,00=1,605,000

1,605,000 is the next year's sales and we do that *0.1 to find the advertising.

1,605,000*0.1=160,500

So 160,500 will be set aside for advertising

What is the 2nd term of the linear sequence

Answers

Answer:

5

Step-by-step explanation

Answer: 5

Step-by-step explanation:

aₙ = a + (n - 1) d

n = the term of the sequence that you're looking for (2)

a = 1st term of sequence (2)

d = common difference (3)

a₂ = 2 + (2 - 1) 3

a₂ = 2 + (1 × 3)

a₂ = 2 + 3

a₂ = 5

It's also given btw but in case you wanted to find other terms of the sequence.

Which expression’s product is modeled by the tiles? A. (x + 1)(x + 3) B. x(x + 3) C. 3(x + 1) D. (3x + 1)(x + 1)

Answers

The product of the expression modeled by the tiles is likely to be (x + 1)(x + 3).

What is expression?

An expression in mathematics is a combination of numbers, variables, and operators that represent a value or a relationship between values. Expressions can be simple or complex, and they can be used to perform mathematical operations or to represent mathematical concepts. For example, the expression 2 + 3 is a simple expression that represents the sum of 2 and 3. The expression x + y is a more complex expression that contains variables, which can take on different values. The expression (x + y)² represents the square of the sum of x and y. In general, an expression can be evaluated to find its value. For example, if we assign the value of 3 to x and the value of 4 to y, then the expression (x + y)²  can be evaluated as (3 + 4)^2 = 7² = 49. Expressions play a fundamental role in mathematics, and they are used in a wide range of mathematical concepts, including algebra, calculus, and geometry.

Here,

This can be deduced from the fact that two tiles with the same x term are placed next to each other and the other two tiles have a constant term.

The product of these two tiles would then be expression (x + 1)(x + 3).

Find the value of x.
A 2
B 4.8
C 6
D 6.4

Answers

Answer:

D

Step-by-step explanation:

Δ DCA and Δ ABE are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{CA}{BE}[/tex] = [tex]\frac{DA}{AE}[/tex] , substitute values

[tex]\frac{18}{10}[/tex] = [tex]\frac{x+8}{8}[/tex] ( cross- multiply )

10(x + 8) = 144 ( divide both sides by 10 )

x + 8 = 14.4 ( subtract 8 from both sides )

x = 6.4 → D

The value of x is the length of BD, so x = 6.So, The correct answer is C. 6.

The value of x is the length of the altitude from vertex B to side AC. We can find this length by using the Pythagorean Theorem on right triangle ABD.

[tex]AB^2 + BD^2 = AD^2\\8^2 + BD^2 = 10^2\\BD^2 = 36\\BD = 6[/tex]

The altitude from vertex B to side AC is equal to the length of BD, so x = 6.

Here is a breakdown of the steps involved in solving for x:

We are given the lengths of sides AB and AC of triangle ABC.

We know that the altitude from vertex B to side AC will be perpendicular to side AC. We can use the Pythagorean Theorem on right triangle ABD to find the length of BD, which is the altitude from vertex B to side AC.

Answer:

Dilate from center A by scale factor of 2, then reflect over line AC

Step-by-step explanation:

(1) Dilate from center A  by  scale factor 2 and then  reflect  over line AC  

hence option (1) is correct.

Given

AC =6

The sequence of transformations   that would show that Δ ABC and  Δ AED are similar

For similar triangles  we can say that sides are proportional

from Δ ABC and  Δ AED  we write that

[tex]\rm \dfrac{AE}{AB } = \dfrac{ED}{BC}= \dfrac{AD}{AC}\\\\\\\rm \dfrac{4}{8} =\dfrac{2}{4} = \dfrac{3}{AC}[/tex]

We can clearly see that scale factor of dilation is 2  (given AC=6) , also we need reflection over line AC.  hence from given options.

(1) Dilate from center A by scale factor 2  and then  reflect  over line AC  

(2)  Dilate from center A  by  scale factor 2   and then  rotate   60° around angle A.

(3) Translate by directed line segment DC and then reflect over line AC.

(4) Dilate from center A  the by  scale factor 4   and then  reflect  over line AC  

hence option (1) is correct.

What is the slope of a line that is perpendicular to the line that passes through the points (9,0) and (3,7)?

work out the size of angle A

Answers

Answer:

The measure of A is 93

Step-by-step explanation:

Here, we want to get the measure of angle A

we can start by getting the measure of angle C

Mathematically, we can use sine rule

It states that the ratio of the length of a side of a triangle and the sine of the angle it faces is constant

So to get C, we have the following;

9/sin 38 = 11/sin C

sin C = 11sin 38/9

sin C = 0.7525

C = sin^-1(0.7525)

C = 48.80

This is approximately 49

To get A,

we know that if we added the measure of interior angles of a triangle, the addition is 180 degrees

Thus, we have it that:

38 + 49 + A = 180

A = 180-38-49

A = 93
