a necklace contains 36 gram of gold 72% of the mass of necklace is gold what is the mass of the necklace

Answers

Answer 1

Answer:

50 grams

Step-by-step explanation:

36 grams = 72%

→ Find 1% by dividing both sides by 72

0.5 grams = 1%

→ Times both sides by 100 to find 100%

50 grams = 100%

Answer 2

Step-by-step explanation:

Multiply 32 by 72 to get thw mass.

Answer:

C.

Step-by-step explanation:

1.) switch x and y

x=(7y+18)/2

2.) multiply both sides by 2

2x=7y+18

3.) subtract 18 from both sides

2x-18=7y

4.) divide both sides by 7

(2x-18)/7=y

Write the Linear equation in Standard form.. Each pair of Socks in store cost 75php, and each pair of gloves costs 50php. If you want to spend exactly 425php, write an equation in standard form modeling this situation. Let x represent the number of pairs of socks you buy, and y represent the number of pairs of gloves you buy.

Answers

Answer:

An equation in standard form modeling this situation is:

75x + 50x = 425

Step-by-step explanation:

Let

x represent the number of pairs of socks you buy

y represent the number of pairs of gloves you buy

Each pair of Socks in store cost 75php, and each pair of gloves costs 50php. If you want to spend exactly 425php.

The equation is given as:

75php × x + 50php × y = 425php

= 75x + 50y = 425

Therefore,

the equation in standard form modeling this situation is:

75x + 50x = 425

A train company moves people between Boston and Providence every day. They travel from city to city 7 times each day. The distance between the two cities is 48 miles. In​ February, there are 28 days. The​ company's budget allows for​ 15,000 total miles in February. Do you think the budget is​ reasonable? Explain.

Answers

Answer: the budget is reasonable since the calculated distance travelled hasn’t exceeded the budget

Step-by-step explanation:

Given data:

Distance between two cities = 48 miles

Number of days available in February = 28

February budget = 15000 miles

Solution:

If the distance between two cities = 48 miles, and 7 trips are made daily

= 48miles * 7

= 336 miles is travelled each day.

For February

= 28days * 336

= 9408 miles.

Budget – travel distance covered ( February)

= 15,000 - 9408

= 5592 miles.

The budget is reasonable because, by following the travel pattern or history the total travelled miles would be 9408 miles for February which is below the budget allowed by the company for the month.

So the budget is reasonable since the calculated distance travelled hasn’t exceeded the budget.

Step-by-step explanation:

1. By interior angle sum Postulate of a triangle.

[tex] m\angle a+ m\angle y +m\angle z= 180\degree.... (1)\\\\

m\angle a+ m\angle w +m\angle x= 180\degree.... (2)\\\\[/tex]

From equations (1) & (2), we find:

[tex] m\angle a+ m\angle y +m\angle z= m\angle a+ m\angle w +m\angle x\\\\

m\angle y +m\angle z= m\angle w +m\angle x\\[/tex]

Hence proved

2. In [tex] \triangle PQS, \: \angle QSR [/tex] is exterior angle.

Therefore, by remote interior angle theorem, we have:

[tex] m\angle QPS + m\angle PQS= m\angle QSR\\\\

x + m\angle PQS= 2x\\\\

m\angle PQS= 2x-x\\\\

m\angle PQS = x.... (1)\\\\

m\angle QPS = x.... (given).... (2)\\[/tex]

From equations (1) & (2), we find:

[tex] m\angle PQS = m\angle QPS\\\\

\therefore \angle PQS \cong \angle QPS\\\\

\therefore PS \cong QS\\(sides\: opposite \: to\: congruent \:\angle s) \\\\[/tex]

[tex] \therefore \triangle PQS [/tex] is an isosceles triangle.

Thus proved.

Answer:

  B.  75.8 ft²

Step-by-step explanation:

The height of each triangle can be found using the Pythagorean theorem. The given edge length (7 ft) is the hypotenuse of the triangle, and the base edge length is twice one leg of the triangle.

The height of the triangle on the 2 ft faces is ...

  √(7² -1²) = √48 = 4√3

The height of the triangle on the 8 ft faces is ...

  √(7² -4²) = √33

The areas of the triangular faces are the product of the height and half the base length:

  A = 1/2bh

  2 ft edge triangle area = (1/2)(2 ft)(4√3 ft) = 4√3 ft²

  8 ft edge triangle area = (1/2)(8 ft)(√33 ft) = 4√33 ft²

__

The area of the rectangular base is ...

  A = LW

  A = (8 ft)(2 ft) = 16 ft²

__

The total surface area of the pyramid is the sum of the areas of the triangular faces and the area of the rectangular base.

  2(4√3 +4√33) +16 = 8(2+√3+√33) ≈ 75.813

The total surface area is about 75.8 ft².

Write the slope-intercept form of the equation for the line that passes through the point (-1,3) and has a slope of 5/3​

Answers

Answer:

[tex]y=\frac{5}{3}x+4\frac{2}{3}[/tex]

Step-by-step explanation:

slope-intercept form: y = mx + b

Given:

Slope(m) = [tex]\frac{5}{3}[/tex]

Point = (-1, 3)

To write the equation in slope-intercept form we need to know the slope(m) and the y-intercept(b). Since we already know the value of m, we can use it and the given point to find b:

[tex]3=\frac{5}{3}(-1)+b[/tex]

[tex]3=-\frac{5}{3}+b[/tex]

[tex]4\frac{2}{3}=b[/tex]

Now that we know the values of b and m, we can write the equation:

[tex]y = \frac{5}{3}x+4\frac{2}{3}[/tex]
