According to the question,

We have the following information:

A sandwich hop serve 4 ounce of meat and 3 ounce of cheese on each sandwich. After making sandwiches for an hour the hop owner has used 91 combined ounce of meat and cheese.

Combined ounces for 1 sandwich:

Ounces of meat + ounces of cheese

4+3

7 ounces

It is given that in an hour 91 ounces of combined cheese and meat are used.

Now, we have:

Number of sandwiches made in 1 hour = 91/7

Number of sandwiches = 13

Ounces of meat used in 13 sandwiches can be found using multiplication as follows:

13*4

Ounces of meat used in 13 sandwiches = 52 ounces

Ounces of cheese used in 13 sandwiches can found using multiplication as follows:

13*3

Ounces of cheese used in 13 sandwiches = 39 ounces

Hence, the combined ounces of meat and cheese used on each sandwich is 7 ounces and the combined ounces of meat on all sandwiches is 52 ounces and that of cheese on all sandwiches is 39 ounces.

Answers

Total number of seats for the center aisle z  = 400 + 10x + Y

The cafeteria would have a total of 3z = 1200 + 30 x + 3y chairs.

What is total?

The word "total" refers to the addition of numbers or the destruction of something, and a total is a whole or full sum. In mathematics, adding two or more integers yields the sum. When you multiply 8 by 8, you get 16.

If z represents the total number of seats, then z=z1 + z2.

The equation for the first ten rows would be 10 (30 + x)= z1.

The equation for the final five rows would be 5 (20 + y) = z2.

Therefore, there would be z= z1+ z2  seats in the center aisle.

So total number of chairs in the middle aisle would be

z= z1+ z2

z= 10 ( 30 + x)+5 ( 20 + y)

z= 300 + 10x + 100 + y

z= 400 + 10x + y

The total number of chairs in the cafeteria would be z +z +z ( for the 3 aisle right , middle and left)

3z = 3(400 + 10x + y)

3z= 1200 + 30 x+ 3y

Total number of seats for the center aisle z  = 400 + 10x + Y

The cafeteria would have a total of 3z = 1200 + 30 x + 3y chairs.

Option D is correct since the side opposite the larger angle is larger and you know that MN>NP, so the angle O's measure is more than the angle Q's measure.

What is angle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Answer:

Step-by-step explanation:

4(x+5) =9x+4x-34

1. we can simplifying the right hand side by adding 9x+4x

this gives us

           4(x+5)=13x-34

2. we expand the brackets to get

           4x+20=13x-34

3. we take the x on one side in this case we will subtract 4x from each side and add 34 on each side to get

          54=9x

4. we divide each side by 9 because we want to find the value of x this gives us

         6=x

x=6

solve in the ( ) to get
4x + 20 = 9x + 4x - 34

then add your like terms (9x & 4x)
4x + 20 = 13x - 34

then add 34 to each side to get
4x + 54 = 13x

then subtract 4x from each side to get
54 = 9x

then divide each side by 9.

54 9x
— = —
9 9x

the right side leaves x and your right side leaves 6 therefore x=6

JP Sports sold football boots on its first day of release. SoccerWorld sold 3 as many boots as JP Sports. DirectSportz sold 5 more boots than JP Sports. Each pair of football boots costs £70 The amount of sales from this particular boot totalled £7000
Work out how many pairs were sold by SoccerWorld.

Answers

The total number of pairs sold by SoccerWorld is 57

How to determine the total number of pairs sold by SoccerWorld?

From the question, we have the following parameters that can be used in our computation:

SoccerWorld sold 3 as many boots as JP Sports

DirectSportz sold 5 more boots than JP Sports.

Cost of each pair = £70

Amount in sales = £7000

The above parameters means that

s = 3j

d = 5 + j

70(s + d + j) = 7000

Where

j = JP Sports

s = SoccerWorld

d = DirectSportz

Divide both sides of 70(s + d + j) = 7000 by 70

s + d + j = 100

Substitute s = 3j and d = 5 + j

3j + 5 + j + j = 100

Evaluate the like terms

5j = 95

Divide by 5

j = 19

Substitute j = 19 in s = 3j

s = 3 * 19

So, we have

s = 57

Hence, the number of pairs is 57

      8                                                     10

So, By definition of proportional, we get;

⇒ Width /Height = 2 / 3

⇒ Width /Height = 4 / 6 = 2 / 3

⇒ Width /Height = 5 / 7

⇒ Width /Height = 8 / 10 = 4 / 5

The standard format for an equation of a straight line is y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).  The slope is -3:

  y = -3x + b

To find b, enter the given point and solve for b:

  -1 = -3*(7) + b  [for (7,-1)]

   b = 20

The equation for this line is y = -3x + 20

Now enter (3,r)

y = -3x + 20

r = -3(3) + 20

r = 11

The point (3,r) is (3,11)

If WXYZ is a rhombus,find the measure of ∠XYZ

Answers

The measure of ∠XYZ is 112° if WXYZ is a rhombus.

What is meant by rhombus?

A quadrilateral with four equal-length sides is known as a rhombus in plane Euclidean geometry (plural rhombi or rhombuses). Another term for this shape is an equilateral quadrilateral since all of its sides are equal in length. The rhombus is frequently referred to as a "diamond" after the diamonds suit in playing cards, which resembles the projection of an octahedral diamond.

Every rhombus is straightforward (does not self-intersect), and it is a particular instance of a parallelogram and a kite. Right-angled rhombuses are called square.

A rhombus's diagonals cut through two opposing angles:

∠YWZ=∠WYZ

Now, we have to substitute ∠YWZ=56° into ∠YWZ=∠WYX: 56°=∠WYX

We have to calculate 56°=∠WYX:∠WYX=56°

The angle addition postulate is, ∠XYZ=∠WYX+∠WYZ

Now, substitute ∠WYZ=56°, ∠WYX=56° into ∠XYZ=∠WYX+∠WYZ

∠XYZ=56°+56°

∠XYZ=112°

John nee 20 gram of a 54% acid olution for hi cience project. Hi chool' cience laboratory ha bottle of 30% olution and bottle of 60% olution. How much of each hould john ue?

Answers

By solving equations we know that he should mix 4 grams and 16 grams of the 30% and 60% bottles, respectively.

What are equations?

In mathematical equations, the equals sign is used to show that two expressions are equal.

According to algebra, an equation is a statement that shows the equality of two mathematical expressions.

For instance, the formulas 3x + 5 and 14, which together make the equation 3x + 5 = 14, are separated by the word "equal."

So, John requires a total of 20 grams.

Let x equal the 30% that he requires.

Let 20-x equal 60% of what he needs.

So, we have:

(x/20 * 30) + (20-x/20 * 60) = 54

Evaluate as follows:

1.5x + 60 -3x = 54

-1.5x = -6

x = 4 grams

20-x = 16 grams

Therefore, by solving equations we know that he should mix 4 grams and 16 grams of the 30% and 60% bottles, respectively.

suppose that 60% of adults in district a support a new ballot measure, while 45% of adults in district b support the same measure. polisters take an srs of 200 adults from district a and a separate srs of 100 adults from district b to see the difference between the sample proportions (paps). what will be the shape of the sampling distribution of pa - bb, and why?

Answers

120 will be the shape of the sampling distribution.

How do you describe the shape of distribution?

Quantitative data's distribution shape may be characterized as having a logical order to the numbers and allowing for the identification of the "low" and "high" end values on the histogram's x-axis. Since qualitative data are not numerical, the distribution shape cannot be specified.

Given that,

Sample size of A, n = 200

Sample size of B, n = 100

Proportion of adults in district A = 60%

Proportion of adults in district B = 45%

In the sample size of 200, the number of adults that support a new ballot measure is:

= (60%) × 200

= 120

Those that oppose is:

= 200 -120

= 80

If 45% supports a new ballot measure in district B, then 55% do not support. The difference between those that support and do not support is:

(55% - 45%) × 100

= 10

Hence, the sampling distribution of p(A) and p(B) is approximately normal, because the number of success in district A is 120.
