Answer:

50 chairs with arms and 50 without arms will cost $7500

Step-by-step explanation:

Create two equations using the given information. The unknowns are :

W  = Number of chairs with arms

N = Number of chairs with No arms

First equation (associated with the total number of chairs to buy):

W + N = 100

Second equation (associated with the amount to spend):

80 W + 70 N = 7500

Solving: solve for W in the first equation: W = 100 - N

Use it to substitute for W in the second equation:

80 (100 - N) + 70 N = 7500

8000 - 80 N + 70 N = 7500

subtract 8000 from both sides and combine

- 10 N = - 500

Divide both sides by -10 in order to solve for N

N = -500 / (-10) = 50

Now use this value in the substitution equation to solve for W:

W = 100 - 50 = 50

So the person can buy 50 chairs with arms and 50 chairs without arms paying for them $7,500.

Answer:

a) red

b) 1/16

c) 7/16

Step-by-step explanation:

probabilities on spinner:

yellow = 1/2

red = 1/4

blue = 1/8

green = 1/8

a) P(odd) = 1/2    1/2 x 1/4 = 1/8   1/4 represents Red

b) P(2, G or R) = 1/6 x (1/8 + 1/4)  = 1/6 x 3/8 = 1/16

c) P(Prime, Not Blue) = 1/2 x 7/8 = 7/16

   * prime numbers on a number cube are 2,3,5

Answer:

The slope of the line m = 1

The equation of the straight line x -y -7=0

Step-by-step explanation:

Explanation:-

In the given graph

The points are ( 7,0) and ( 0, -7)

The slope of the line

            [tex]m = \frac{y_{2}- y_{1} }{x_{2}-x_{1} } = \frac{-7-0}{0-7} = \frac{-7}{-7} = 1[/tex]

The equation of the straight line passing through the point (7,0) and slope m=1

    y - y₁ = m (x - x₁)

    y - 0 = 1( x-7)

   y = x -7

   x - y -7=0

Final answer:-

The slope of the line m = 1

The equation of the straight line x -y -7=0

Answer:

71.092

Step-by-step explanation:

The number in the standard form i.e. seventy-one and ninety-two thousandths should be considered as the 71.092.

Since the numbers are mentioned in alphabets like

seventy-one and ninety-two thousandths

We have to write in standard form

So, it should be like 71.092.

Hence, The number in the standard form i.e. seventy-one and ninety-two thousandths should be considered as the 71.092.

Answer:

We conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p      

Step-by-step explanation:

Let 'p' be the original price

Discount = 5% = 0.05

The discount amount can be calculated by multiplying the original price by 5% or 0.05

Discount Amount = 5% × p

                             = 0.05 × p

                             = 0.05 p

Given that the price p of a coat reduced by a 5% discount​.

Thus, the price after 5% discount​ can be calculated by subtracting the discount amount i.e. 0.05 p from the original price p.

Thus,

The expression of the price p after 5% discount​ = p - 0.05 p

                                                                                = 0.95 p

Therefore, we conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p

Answer:

Step-by-step explanation:

when graphing inequalities if the shaded region is below the line then it is less than. Solid line makes it equal to. Line is going downwards so slope is negative. y intercept is in the negative region.

The inequality which is shown in this graph is y ≥ 2x - 2, the correct option is C.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

An inequality is a mathematical statement that compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to describe relationships between quantities or to express constraints or conditions.

We are given that;

The graph

Now,

The inequality that is shown in this graph is C. y ≥ 2x - 2. This is because the graph shows a solid line with a slope of 2 and a y-intercept of -2, which is the equation y = 2x - 2. The solid line means that the points on the line are included in the solution set of the inequality. The shaded region above the line means that the points in that region satisfy the inequality.

Therefore, by the inequality the answer will be y ≥ 2x - 2.

Answer:

total surface area = 76 sq.cm

Step-by-step explanation:

total surface area of cuboid = 2 ( lb + lh + bh )

( where l is length , b is width and h is height )

so, surface area :

= 2[ (5×4) + (5×2) + (2×4) ]

= 2 [ 20 + 10 + 8 ]

= 2 × 38

= 76 sq.cm

Answer:

1) 145°

2) 20°

3) x = 7 ; measurement of the missing angle = 24

Step-by-step explanation:

1) supplement = 180°, 180 - 35 = 145

2) complment = 90° , 90 - 70 = 20

3) the figure is a right angle so the measurement is 90°

66 + (4x-4) = 90

62 + 4x = 90

4x = 28

x = 7

Answer:

m∠BAD = 88.83°

Step-by-step explanation:

By drawing a diagonal BD, we get a triangle ABD from the given rectangle pyramid.

Length of the diagonal BD (diagonal of rectangle BCDE) = [tex]\sqrt{\text{Length}^{2}+\text{Width}^2 }[/tex]

                                                                                              = [tex]\sqrt{12^{2}+16^{2}}[/tex]

                                                                                              = [tex]\sqrt{400}[/tex]

                                                                                              = 20 cm

By applying cosine rule in ΔABD,

BD² = AB² + AD²- 2(AB)(AD)cos(∠BAD)

20² = 14² + 14² - 2(14)(14)cos(∠BAD)

400 = 196 + 196 - 392cos(∠BAD)

400 - 392 = 392cos(∠BAD)

cos(∠BAD) = [tex]\frac{8}{392}[/tex]

m(∠BAD) = [tex]\text{cos}^{-1}(\frac{8}{392})[/tex]

               = 88.83°

Answer: The perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Sides of smaller triangle = 10,20 and 15 units

Longest side = 20 units

Longest side of larger triangle = 52 units

Sides of two similar triangles are proportional.

Let k be proportionality constant.

[tex]k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}[/tex]

[tex]k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}[/tex]

Length of other two sides,

[tex]10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}[/tex]

So sides of larger triangle = 52 units, 26 units , 39 units

Perimeter of largest triangle = 52 +26+39 = 117 units

Hence, the perimeter of the largest triangle = 117 units.

Answer:

right angle

Step-by-step explanation:

180-(31+59)= 90

The correct classification of the triangle should be considered as the right triangle.

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangled triangle, is a triangle in which one angle is a right angle, i.e., in which two sides are perpendicular. The relation between the sides and other angles of the right triangle is the basis for trigonometry.

here, we have,

given that,

In the case when the sum the two given angles is 90,

so, the other angle will be 90

so, its a right triangle.

A right angled triangle is a triangle in which one of the angles is 90°. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle. Further, based on the other angle values, the right triangles are classified as isosceles right triangles and scalene right triangles.

Hence, The correct classification of the triangle should be considered as the right triangle.

Step-by-step explanation:

Hi there!

Question 4 - the answer will be 5. Since the scale factor is 5, we would (hypothetically) multiply the area by 5 to get the new area of XYZ, so area XYZ is 5 times the area of ABC.

Question 5 - A.

First we multiply 45 by 12 to find the amount in inches. This is 540. Now, we divide that by 6 to get 90. This is our scale factor in inches, but the answers only show the scale in feet, so we have to convert. Divide 90 by 12 to get 7.5.
