Answer: 3 1/3 liter

Brainliest? <3

let x equal the number of liters of 15% weedkiller.

your equation is .15 * x + .10 * 5 = .12 * (x + 5)

simplify to get .15 * x + .10 * 5 = .12 * x + .12 * 5

simplify further to get .15 * x + .5 = .12 * x + .6

subtract .12 * x from both sides and subtract .5 from both sides and simplify to get .03 * x = .1

divide both sides by .03 to get x = .1 / .03 = 3.333333333 rounded to 9 decimal digits.

you would need 3.333333333 liters of 15% solution to be added to 5 liters of 10% solution to get 8.333333333 liters of 12% solution.

.15 * 3.333333333 = .5

.10 * 5 = .5

.5 + .5 = 1

5 + 3.333333333 = 8.333333333

1 divided by 8.333333333 = .12 which is equal to 12%.

[tex]\frac{121}{16}[/tex]

Step-by-step explanation:

[tex](-2\frac{3}{4})^2\\= (-\frac{4\times2+3}{4})^2\\=(-\frac{11}{4})^2\\=\frac{121}{16}[/tex]

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.

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

Answer:

C 12.50b+22.50n≥800

Step-by-step explanation:

Tonya is staring a jewelry business. She is going to sell b bracelets for $12.50 each and n necklaces for $22.50. Tonya wants to make at least $800 a month.

When we use the word at least in Mathematics is means that it is equal to or more than $800.

It is represented by the symbol ≥

Number of bracelets = b

Number of necklaces = n

Therefore, the inequality below models this situation is given as:

$12.50 × b + $22.50 × n ≥ $800

= 12.50b + 22.50n ≥ 800

Option C is correct.

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:

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:

17.61

Step-by-step explanation:

82.50 x 0.0675 = 5.57

82.50 + 5.57 = 88.07

88.07 x 0.20 = 17 61

Answer:

y=3/5x+1 because when a line is perpendicular to another line the slope it the opposite meaning negative to positive or positive to negative

you also reverse the number/ fraction...for example, if the slope was 2 the slope in the other equation would be -1/2. if the slope in the first equation was 1/2 the second equation slope would be -2 since it is the opposite and flipped

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.

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:

C. 48 lizards and 24 frogs

Step-by-step explanation:

Let F = number of frog lures, and let L = number of lizard lures.

Marion bought 14 packages of plastic frog and lizard fishing lures.

She bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures.

F + L = 72

F/4 + L/6 = 14

12 * F/4 + 12 * L/6 = 12 * 14

         3F + 2L = 168

(+)      -3F - 3L = -216

------------------------------

                   -L = -48

L = 48

F + L = 72

F + 48 = 72

F = 24

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.
