How can I get -1 with theses answers
LiRa [457]
You can't get negative 1 from any equation shown in this picture. By the way, -5 +(-9) is not negative 4, it is negative 14,because according to PEMDAS( or <span>BODMAS/BIDMAS/BEDMAS )</span>,  parenthesis goes first, so it's kinda like
(-9) + -5 instead.

Kindly i need solution of these both parts a and b which are attached below

Answer:

  a) 252 cm³, 252 cm², 705.6 g

  b) 240 cm³, 252 cm², 672 g

Step-by-step explanation:

The volume of each figure can be computed as the product of the base area (the side facing the viewer) and the "height" of the prism (the distance between bases).

The surface area of the prism is the sum of the two base areas and the "lateral area" consisting of the product of the base perimeter and the "height" of the prism.

The mass will be the product of volume and density.

__

ai) The base is a 3 cm by 8 cm rectangle together with a trapezoid with bases 3 cm and 6 cm, and height 7 - 3 = 4 cm.

  B = (3 cm)(8 cm) +(1/2)(3 cm +6 cm)(4 cm) = 24 cm² +18 cm² = 42 cm²

The "height" is 6 cm, so the volume is ...

  V = Bh = (42 cm²)(6 cm) = 252 cm³

__

aii) The perimeter of the base is the sum of its side lengths. Clockwise from left, the lengths are ...

  (8 +3 +2 +5 +3 +7) cm = 28 cm

Then the lateral area is ...

  LA = Ph = (28 cm)(6 cm) = 168 cm²

Adding this to the areas of the two bases, we get the total surface area:

  A = LA +2B = (168 cm²) + 2(42 cm²) = 252 cm²

__

aiii) The mass is the product of volume and density:

  M = ρV = (2.8 g/cm³)(252 cm³) = 705.6 g

____

bi) This trapezoidal prism has a base that has bases of 6 and 9 cm, and a height of 4 cm. The area of the base is ...

  B = (1/2)(b1 +b2)h = (1/2)(6 cm + 9cm)(4 cm) = 30 cm²

Then the volume is ...

  V = Bh = (30 cm²)(8 cm) = 240 cm³

__

bii) The lateral area is the perimeter of the base times the height of the prism:

  LA = Ph = (4 +6 +5 +9 cm)(8 cm) = 192 cm²

The total area is this area plus that of the two bases:

  A = LA +2B = (192 cm²) +2(30 cm²) = 252 cm²

__

biii) M = ρV = (2.8 g/cm³)(240 cm³) = 672 g

of 360 consumers polled some purchase ice cream some purchase frozen yogurt and some purchase both if 260 people polled purchase
uysha [10]

Answer: There are 350 consumers who purchase frozen yogurt.

Step-by-step explanation:

Since we have given that

Number of consumers polled =360

Number of consumers who purchased ice- cream = 260

Number of consumers who purchased both ice- cream and frozen yogurt = 250

We need to find the number of consumers who purchased frozen yogurt,

Let A denotes who purchased ice-cream

and B denotes who purchased frozen yogurt.

As we know the formula

n(A\cup B)=n(A)+n(B)-n(A\cap B)\\\\360=260+n(B)-250\\\\360=10+n(B)\\\\360-10=n(B)\\\\350=n(B)

Hence, there are 350 consumers who purchase frozen yogurt.
