Answer:

Improper fraction = 10/3 cups

Mixed fraction = 3 1/3 cups

Step-by-step explanation:

Given;

Sam uses 2/3 cup of sugar to make cookies

Rate = 2/3 cup per batch

To make 5 batches, he would need;

Amount = number of batches × rate per batch

Amount = 5 batches × 2/3 cups per batch

Amount of sugar he would need = 10/3 or 3 1/3 cups

Answer:

9 × (1 × 4) = (9 × 1) × 4

Step-by-step explanation:

Number 3 because the associative property states that it doesn't matter how you add / multiply something in sets.

9 × (1 × 4) = (9 × 1) × 4 shows 9 × 1 × 4 in 2 ways with 2 sets.

Answer:

9 × (1 × 4) = (9 × 1) × 4 is the answer because it means you can group in any combination

Step-by-step explanation:

9 × (1 × 4) = (9 × 1) × 4

Answer:

Step-by-step explanation:

They are dividing the denominator by 3. So, the answer is 2/1 or basically the number 2.

For example,

The last math shows how I got the answer.

Hope this helps!

Answer:

2

Step-by-step explanation:

The sequence is multiplying by 3 each time.  2/27 *3= 2/9

2/9 *3 is 2/3.

2/3*3= 2

2 is the next term

Answer:

x = 9

Step-by-step explanation:

→Looking at the angles, you can see that a right angle is formed. This means that there must be another right angle (90 degrees) formed with the numbers. You can set up the equation, like so:

3x + 6 + 57 = 90

→Add like terms (6 and 57):

3x + 63 = 90

→Subtract 63 from both sides:

3x = 27

→Divide both sides by 3:

x = 9

Answer:

x=9

Step-by-step explanation:

a right angle is 90 degrees

90-57= 33

33-6=27

27/3 = 9

Answer:

y+1/2= 3(x - 2)

Step-by-step explanation:

The slope can be seen to be 3 by factoring out each of the right sides.  Only a and c have a slope of 3.  Next if the point (2,-1/2) is plugged into the equation of c then you get an answer of 0=0.  Beacuse both sides are equal when the point desired is plugged in it is the correct answer.

The simplified value is 8*cos^4(x) = 3+ 4 cos2x + cos 4x.

The trigonometric power reduction identities allow us to rewrite expressions involving trigonometric terms with trigonometric terms of smaller powers. This becomes important in several applications such as integrating powers of trigonometric expressions in calculus.

Given:

Using the power reduction identity, we have that:

cos² x= 1/2( 1+ cos 2x)

cos^4(x) = (cos² x)²= (1/2( 1+ cos 2x))²

cos^4(x) =  1/4( 1+ cos² 2x+ 2 cos (2x))

Again, cos² 2x= 1/2( 1+ cos 4x)

cos^4(x) =  1/4( 1+ 1/2( 1+ cos 4x)+ 2 cos (2x))

cos^4(x) =  1/4( 1+ 1/2 +1/2 cos 4x+ 2 cos (2x))

cos^4(x) =  1/4( 3/2 + 2 cos2x + 1/2 cos 4x)

8*cos^4(x) =  8*1/4( 3/2 + 2 cos2x + 1/2 cos 4x)

8*cos^4(x) =  2( 3/2 + 2 cos2x + 1/2 cos 4x)

8*cos^4(x) = 3+ 4 cos2x + cos 4x

Answer:

x =348 ^ (1/7)

Step-by-step explanation:

x^7-116=232

Add 116 to each side

x^7-116+116=232+116

x^7 =348

Take the 7th root each side

x^7 ^ 1/7 = 348 ^ (1/7)

x =348 ^ (1/7)

Answer:

Answer 1: a. Moonlight: C=75n+1000

Riverside: C=50n+1500

Answer 2: c. The solution coordinates are c. (20, 2500)

Answer 3: c. When there are 20 guests attending the price is $2500.

Step-by-step explanation:

Moonlight Hall:

Fixed cost = $1000

Cost per guest = $75

Cost of 'n' guests = 75 [tex]\times n[/tex]

Total cost of moonlight hall = Fixed cost + Cost of 'n' guests

[tex]\Rightarrow 1000 + 75 \times n[/tex]

Riverside Hall:

Fixed cost = $1500

Cost per guest = $50

Cost of 'n' guests = 50 [tex]\times n[/tex]

Total cost of moonlight hall = Fixed cost + Cost of 'n' guests

[tex]\Rightarrow 1500 + 50 \times n[/tex]

Hence, Answer 1:

a. Moonlight: C=75n+1000

Riverside: C=50n+1500

Answer 2: Coordinates of solution:

Option c. (20,2500) satisfies both the equation.

When there are 20 number of guests, the cost of both moonlight and riverside hall comes out to be 2500.

Moonlight Hall cost

[tex]75 \times 20 + 1000\\\Rightarrow \$2500[/tex]

Riverside Hall cost

[tex]50 \times 20 + 1500\\\Rightarrow \$2500[/tex]

Answer 3: c. When there are 20 guests attending the price is $2500.

The solution is done in Answer 2.

Answer 1: a. Moonlight: C=75n+1000

Riverside: C=50n+1500

Answer:

angle BAC = 57.84°

Step-by-step explanation:

To find angle BAC given AB=6cm    BC= 13 cm   and ACB=23°

we will follow the steps below;

we can use the sine formula to solve the problem given

[tex]\frac{sin A}{a}[/tex] = [tex]\frac{sin C}{c}[/tex]

from the question given;

A = ?

C = 23°

c=AB  = 6 cm

a=BC = 13 cm

substitute the values into the formula above

[tex]\frac{sin A}{a}[/tex] = [tex]\frac{sin C}{c}[/tex]

[tex]\frac{sin A}{13}[/tex]  =  [tex]\frac{sin 23}{6}[/tex]

cross -multiply

6 sinA =  13 sin23°

sin A = 13 sin23°  /  6

sin A = 0.84658

take the [tex]sin^{-1}[/tex] of both-side

[tex]sin^{-1}[/tex] sin A =  [tex]sin^{-1}[/tex] (0.84658)

on the left-hand side of the equation [tex]sin^{-1}[/tex] will cancel-out sin leaving us with just A

A =  [tex]sin^{-1}[/tex] (0.84658)

A ≈ 57.84°

angle BAC = 57.84°

Use the distance formula to calculate the length of all three sides, and check whether all sides are congruent.

An equilateral triangle would have three sides that are all the same length, out of these options, only using the distance formula to calculate the length of all three sides and checking whether they are all congruent will make sure that the triangle is equilateral instead of just isosceles.

Answer:

The answer is B

the horizontal is the graph function of x

Answer & Step-by-step explanation:

In order to solve this problem, we are going to have to divide. Since the triangles are similar, then that means that we are going to have to find the ratio between the sides which will also be our scale factor.

We can divide 75 by 15 since they are corresponding sides. Once we find the ratio between the sides, then we can conclude that the scale factor would be that number.

75 / 15 = 5

So, the scale factor of XYZ to UVW is 5.

The scale factor of [tex]Xyz[/tex] to [tex]UVW[/tex] is 5.

The ratio that we get when you divide corresponding side lengths of similar figures is called the scale factor.

According to the given question.

We have a two triangles Xyz and UVW. And both the triangles are similar to each other.

In triangle Xyz we have

[tex]Xy = 60[/tex]

[tex]yz = 75[/tex]

and

[tex]zX = 90[/tex]

Also, in triangle UVW we have

[tex]UV = 12[/tex]

[tex]VW = 15[/tex]

and, [tex]WU = 18[/tex]

Therefore, the scale factor of Xyz to UVW is given by

[tex]\frac{Xy}{UV} =\frac{yz}{VW} =\frac{zX}{WU}[/tex]

⇒ [tex]\frac{60}{12} =\frac{75}{15} =\frac{90}{18} =5[/tex]

Hence, the scale factor of [tex]Xyz[/tex] to [tex]UVW[/tex] is 5.

Thus option B is correct.
