Answer:

54 ft

Step-by-step explanation:

1/4=3 ft, if you convert the measurements to feet, it adds up to 54

Answer:

one side is 6 feet, one side is 21 feet

(21 x 2) + (6 x 2) = 54 feet

Step-by-step explanation:

Given:

The expression is

[tex]-\dfrac{2}{5}\ \div\left(\dfrac{8}{7}\times\dfrac{-7}{8}\right)\ \div-1[/tex]

To find:

The numerical value of the given expression.

Solution:

We have,

[tex]-\dfrac{2}{5}\div\left(\dfrac{8}{7}\times\dfrac{-7}{8}\right)\ \div-1[/tex]

On simplification, we get

[tex]=-\dfrac{2}{5}\div\left(-1\right)\ \div-1[/tex]

[tex]=-\dfrac{2}{5}\div \dfrac{-1}{-1}[/tex]

[tex]=-\dfrac{2}{5}\div 1[/tex]

[tex]=-\dfrac{2}{5}[/tex]             [tex][\because a\div 1=a][/tex]

Therefore, the numerical value of the given expression is [tex]-\dfrac{2}{5}[/tex] and the correct option is B.

Answer:

[tex]y = 2(0.5) {}^{x} [/tex]

Step-by-step explanation:

Use the general formula of exponential equation

[tex]y = ab {}^{x} [/tex]

Plug 0,2 into the function

[tex] - 2 = ab {}^{0} [/tex]

[tex] - 2 = a \times 1[/tex]

[tex]a = - 2[/tex]

[tex]y = - 2b {}^{x} [/tex]

[tex] - 4 = - 2b {}^{ - 1} [/tex]

[tex]2 = b {}^{ - 1} [/tex]

[tex] {2}^{ \frac{ 1}{ - 1} } [/tex]

[tex]2 {}^{ - 1} = 0.5[/tex]

B=0.5

[tex]y = 2(0.5) {}^{x} [/tex]

Angle three would also be thirty, and the other two angles (2+4) would be 180 (the degrees in a straight line ALWAYS) minus 30, which would be 150. The answer your looking for would be 30 though.

Answer:

The amount of change will be £7.99

Step-by-step explanation:

Here, we want to calculate the amount of change that Mehvish should get

1/2 kg carrots at 50 p per kg will be;

1/2 * 50 = 25 p

3 kg potatoes at 64 p per kg will be

3 * 64 = p 192

2 kg onions at 42 p per kg

2 * 42 p = 84 p

1 1/2 kg chicken at £6 per kg will be:

since £1 is 100 p

1.5 * 6 = £9 (9 * 100 p = 900p)

since £1 is 100 p

£20 will be;

20 * 100 = 2,000 p

So let us make the subtraction as follows;

2,000- 900 - 84-192 - 25 = 799 p

In pounds, this is divided by 100

we have this as 799/100 = £7.99

Answer:

$63

Step-by-step explanation:

$252 ÷ 4 = $63

Answer:

Step-by-step explanation:

The family bought 4 tickets

The total cost is $252

So that means you have to divide $252 by the number

of tickets bought which is 4

$252÷4=$63

Answer: Each ticket cost $63

Answer:

$2.58

Step-by-step explanation:

4.45*0.42 = 1.87

4.45 - 1.87 = 2.58

When you multiply things under 0, but still positive, you get the percentage,

for example 0.42 is 42 percent, 0.50 is 50%, and 0.15 is 15%. Which is why you multiply 0.42 by 4.45, you get 1.87.

4.45 minus 1.87 because,

You have 42% of 4.45, but you need to take 42% off.

Given:

Price of a new car = 25000

Depreciation rate = 8.25% = 0.0825

Time = 15 years.

To find:

The value of the car after 15 years.

Solution:

The exponential decay model is

[tex]y=a(1-r)^t[/tex]

Where, a is the initial value, r is the rate of decay and t is number of years.

Putting a=25000, r=0.0825 and t=15 in the above formula.

[tex]y=25000(1-0.0825)^{15}[/tex]

[tex]y=25000(0.9175)^{15}[/tex]

[tex]y=25000(0.274847)[/tex]

[tex]y=6871.175[/tex]

Therefore, the value of the car after 15 years will be 6871.175.

The value of the measure of angle B will be;

⇒ ∠ B = 87.13°

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The value is,

⇒ cos B = 0.05

Now,

Since, The value is,

⇒ cos B = 0.05

Taking cos inverse both side, we get;

⇒ cos⁻¹ cos B = cos⁻¹ 0.05

⇒ B = 87.13°

Thus, The value of angle B = 87.13°

Answer:

Option D

Step-by-step explanation:

By inscribed angle theorem,

" Measure of an inscribed angle by the arc measures half of the measure of the arc"

m(arc BCD) = 2m(∠BED)

And m(arc BCD) = m(arc BC) + m(arc CD)

m(arc BC) + m(arc CD) = 2m(∠BED)

64° + m(arc CD) = 2(62°)

m(arc CD) = 124 - 64

                 = 60°

Option D is the answer.

What is the objective to answer the question? Is it how much they will get?

Answer:

y = -7

Step-by-step explanation:

5x+8y=29

5(17)+8y=29 (simplify by multiplying)

85+8y=29 (subtract 85 from both sides)

8y= -56 (divide both sides by 8y)

y = -7

Answer:

5%

Step-by-step explanation:

A tax is a compulsory sum levied by the government or an agency of the government on goods and services. Taxes raises the price of products

Tax rate is the percentage a person pays as tax

tax rate = [tex]\frac{tax paid}{cost of the dinner}[/tex] × 100

[tex]\frac{7.89}{157.75}[/tex] × 100 = 5%

She paid a tax rate of 5% on the dinner
