Answer:

Breadth of stamp=3 cm

Length of stamp=4 cm

Area of stamp = Area of rectangle = l*b = 3*4 = 12 cm^2

Side of square card = 12 cm

Area of card = Area of square = side^2 = 12^2 = 144 cm^2

No. of stamps that can be filled in card

= Area of card / Area of stamp

= 144/12

= 12

:. 12 stamps can be filled in a card of side 12 cm.

Answer:

5; 12; 24; 12.

Step-by-step explanation:

1) if D is midpoint, then 2*CD=CE, it means

2) 2(x+7)=5x-1; ⇔ 3x=15; ⇒ x=5;

3) CD=x+7; ⇒ CD=12;

CE=5x-1; ⇒ CE=24;

DE=CD; ⇒ DE=12.

Step-by-step explanation: I hope this helps.

Answer: The answer is B.

When E = 4 on the number line, then F can either be 11 or be 19 to make EF as 15 units.

We are given that:

E and f are the points on a number line.

We are also given that the distance between E and F is:

EF = 15 units

Now, we know that E lies at 4

E = 4

We need to find the location of the point F

Now, since we also know that:

EF = F ± E

Substituting the values:

15 = F ± 4

We get that:

15 = F + 4   or   15 = F - 4

F = 15 - 4    or   F = 15 + 4

F = 11           or   F = 19

Therefore, we get that, when E = 4 on the number line, then F can either be 11 or be 19 to make EF as 15 units.

Answer:

y = mX - mx

Step-by-step explanation:

X - (y/m) = x

Multiply everything by m

(m)X - (y/m)(m) = x(m)

mX - y = mx

-mX        -mX

-y = mx - mX

Divide both sides by -1

-y = mx - mX

÷ -1       ÷ -1

y = -mx + mX

or

y = mX - mx

Answer:

0.035 kg

Step-by-step explanation:

(0.07 kg / 1 litre) x (0.5 litre)

= 0.035 kg

Notice how the units of litres cancel and all you are left with is units of kg which is what we want. Another way of solving this problem is via logic. If 1 litre of water is needed for 0.07 kg salt, then half a litre of water (0.5) would need half of the amount needed by 1 litre water so (0.07/2) = 0.035 kg

Answer:

h = -13

Step-by-step explanation:

Use PEMDAS to solve this problem.

11h - 5(h + 3) = -63

~Use distributive property to simplify [ a(b + c) = ab + ac ]

11h - 5h + 15 = -63

~Combine like terms

6h + 15 = -63

~Subtract 15 to both sides

6h = -78

~Divide 6 to both sides

h = -13

Best of Luck!

Answer:

Step-by-step explanation:

11h - 5(h + 3) = -63

-Multiply parenthesis so

-5(h) + -5(3) = -5h - 15

New equation: 11h - 5h - 15= -63

                                   +15  +15

(add 15 to both sides)

Answer:

a = 130

b = 50

Explanation:

Analyze that the angles a and b lies on a straight line summing up to 180°.

Equation's:

make 'a' subject in eq 1

a + b = 180

a = 180 - b

substitute this into eq 2

a - b = 80

(180 - b) - b = 80

180 - 2b = 80

-2b = 80 - 180

-2b = -100

b = 50

Find value of 'a':

a = 180 - b

a = 180 - 50

a = 130

Answer:

a = 130°, b = 50°

Step-by-step explanation:

The given equation is,

→ a - b = 80°

→ a + b = 180°

The equation we form is,

→ (a + b) + (a - b) = 180 + 80

Now the required value of a will be,

→ (a + b) + (a - b) = 180 + 80

→ (a + a) + (b - b) = 260

→ 2a = 260

→ a = 260/2

→ [ a = 130° ]

Hence, the value of a is 130°.

Then the required value of b will be,

→ a + b = 180

→ 130 + b = 180

→ b = 180 - 130

→ [ b = 50° ]

Hence, the value of b is 50°.

The value of the square in the mathematical identity is 1.

According to the statement, We have to find that the value of the square.

So, For this purpose, we know that the

Step-by-step explanation:

The percent of the computer programmer’s salary deducted for income tax is 17%.

What is percentage of a number?

A percentage is a ratio or number that can be expressed as a fraction of 100. In order to calculate a percentage of a number, we must divide it by 100 and then multiply the resulting number by 100. The proportion therefore denotes a component per 100. A percentage of one hundred is what is meant by the word "percent."

Given, weekly wage is $1350 and deduction amount for income tax is $229.50.

The percent of deduction is

[tex]\frac{229.50}{1350} \times 100\\=0.17 \times 100\\=17[/tex]

Therefore, the percent of the computer programmer’s salary deducted for income tax is 17%.
