Step-by-step explanation:
For $7.90, you purchased 8 items (pens and highlighters) from a local bookstore. Each highlighter cost $1.09 and each pen cost $.68. Write a system of equations that can be used to find how many of each you bought.
A. 8p+8h=7.90 and 1.09+.68h=7.90
B. h+p=8 and .68h+ 1.09p=7.90
C. p+h=7.90 and .68p+1.09h=8
D. h+p= and 1.09h+.68=7.90
Answer:
D, i believe it should be h+p=8 and 1.09h + 0.68p = 7.90
Step-by-step explanation:
purchased 8 items in total; therefore, h+p=8
cost of each item, multiplied by quantity, equals grand total of $7.90

Cut out the shapes of NETS of Cube, Cuboid and Cylinder as per the dimensions given below and find its Total Surface Area and Lateral Surface Area Dimensions of Cube = 5cm x 5cm x 5cm Dimensions of Cuboid = Length=10cm, Breadth=5cm, Height = 4cm Dimensions of Cylinder= Diameter 7cm and height 10cm
Answer:
a. i. 150 cm³ ii. 150 cm³
b. i. 220 cm³ ii. 120 cm³
c. i. 297 cm² ii. 220 cm²
Step-by-step explanation:
a. For the cube
Dimensions of Cube = 5cm x 5cm x 5cm
Length of side = 5 cm
i. Total surface area A = 6L² where L = length of side = 5 cm
So, A = 6 × (5 cm)²
= 6 × 25 cm³
= 150 cm³
ii. Lateral surface area A' = 4L²
= 4 × (5cm)²
= 4 × 25 cm²
= 100 cm²
b. For the cuboid
Dimensions of Cuboid = Length, l = 10cm, Breadth, b = 5cm, Height, h = 4cm
i. Total surface area A = 2(lb + lh + hb)
= 2(10 cm × 5 cm + 10 cm × 4 cm + 4 cm × 5 cm)
= 2(50 cm² + 40 cm² + 20 cm²)
= 2(110 cm²)
= 220 cm²
ii. Lateral surface area A' = 2(lh + hb)
= 2h(l + b)
= 2 × 4 cm (10 cm + 5 cm)
= 8 cm × 15 cm
= 120 cm²
c. For the cylinder
Dimensions of Cylinder = Diameter, d = 7cm and height, h = 10cm
i. Total surface area, A = 2πr(r + h) where r = radius = d/2
A = πd(d/2 + h)
= 22/7 × 7 cm(7 cm/2 + 10 cm)
= 22cm(3.5 cm + 10 cm)
= 22cm(13.5 cm)
= 297 cm²
ii. Lateral surface area A = 2πrh
= πdh
= 22/7 × 7 cm × 10 cm
= 22 cm × 10 cm
= 220 cm²

A table with marked price Rs1200 was sold to a customer for Rs1100.Find the rate of discount allowed on the table. Find Discount Percentage.. Plzz solve this question..
Answer:
1200
Step-by-step explanation:
Step-by-step explanation:
Given that,
Marked price of a table is ₹1,200
And was sold to a customer at ₹1,100
As we need to find the discount,
Therefore
We know that,
➡ Discount = M. P. - S. P.
➡ Discount = 1,200 - 1,100
➡ Discount = ₹100
Now,
Discount% = discount/M.P. × 100
= 100/1,200 × 100
= 8⅓% discount

If 2 is divided into pieces that are each 1/7 of a whole, how many pieces are there?
Answer:
There are 14 pieces in 2 wholes.
Step-by-step explanation:
In order to solve this question we need to understand that "a whole" is another way of saying 1. So then this question askes the following, "How much does [tex]\frac{1}{7}[/tex] fit into 2. In order to find that out we just have to divide 2 by [tex]\frac{1}{7}[/tex] and so we get.....
2 / [tex]\frac{1}{7}[/tex] = 14
