The sides of a triangle are in the ratio 1: 2: 4. The difference between the longest side
and the shortest side is 84 cm. What is the perimeter of the triangle?

Answers

Question:-

The sides of a triangle are in the ratio 1 : 2 : 4. The difference between the longest side and the shortest side is 84 cm. What is the perimeter of the triangle ?

Solution:-

The sides of a triangle are in the ratio 1: 2: 4. (Given)

Let the three sides of a triangle be x, 2x and 4x respectively.

So,

ATQ ,

4x - x = 84

3x = 84

x = [tex] \bf \frac{84}{3} [/tex]

x = 28

[tex] \therefore [/tex] Longest side = 4x = 4 × 28 = 112 cm.

Shortest side = x = 28 cm.

And, the other side = 2x = 2 × 28 = 56 cm

Now, we have to find the perimeter of the triangle.

Hence, Perimeter of the triangle = (112 + 56 + 28) cm = 196 cm.

The perimeter of the triangle is 196 cm. [Answer]

A construction worker earned $64 in a week. If he worked eight hours in one week, how much money did he earn per hour?

Answers

Answer:

X=8

Step-by-step explanation:

64 Divided by Eight equals Eight.

Because he worked eight hours that week and earned $64 so divide that up by eight then you got your answer.

9.14 you divide 64 by 7 since that’s a week plus you multiply 9.14 by 7 it give you 63.98

The length of a rectangular garden is 8m greater than twice the width the area of the garden is 280m^2 what is the width of the garden

Answers

Step-by-step explanation:

Given :-

The length of the garden 8m greater than 2 times the width.

Area of the garden is 280 m²

Let us consider the length as x and width as y.

Sp, we can day length as :-

x = 8 + 2y ---(1)

Now, we know that:-

Area of Rectangle = Length × Breadth

280 = x * y

We can replace the value of x now,

280 = y × ( 8 + 2y)

280 = 8y + 2y²

2y² + 8y - 280 = 0

y² + 4y - 140 = 0

Factorise it.

(y -10)(y + 14)

Cancelling -ve value, we get the width as 10 metres.

Hope it helps :)

Answer:

Step-by-step explanation:

Width = w

Length = 2w + 8

Area of rectangular garden = 280 square meter

length * width = 280

(2w + 8 ) *w = 280

2w * w + 8*w = 280

2w² + 8w = 280

2w² + 8w - 280 = 0

Divide the whole equation by 2

w² + 4w - 140 = 0

w² + 14w - 10w - 14 *10 = 0

w(w + 14) - 10(w + 14) = 0

(w + 14)(w - 10)= 0

w - 10 = 0 {Ignore w + 14, as measurements will not be -ve}

w = 10 m

l = 2*10 +8

= 20 +8

l = 28 m

If the school has 1,000 students, about how many students can the cafeteria expect to buy pizza?
208
1,000
260
52

Answers

Answer:

260

Step-by-step explanation:

you would divide 52/200 because all the numbers added up is 200 and it comes out to 0.26 and the original number of students they wanted is 1,000 so look at those zeros and move the decimal 3 times and add the zero in the empty space to get 260.

A ratio shows us the number of times a number contains another number. The number of students the cafeteria should expect to buy pizza is 260.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

The ratio of the number of students to the number of total students can be written as,

Ratio = (Number of students)/(Number of total students)

Ratio = 52/(52+26+30+48+44) = 52/200

Now, the same ratio is applicable to 1000 students, therefore, the ratio will be,

Number of students who prefer pizza = 1000 × (52/200) = 260

Hence, the number of students the cafeteria should expect to buy pizza is 260.

Answer:

(-3 + -2y)(5 + -1y) = 0

Step-by-step explanation:

Simplifying

(y + -5)(2y + 3) = 0

Reorder the terms:

(-5 + y)(2y + 3) = 0

Reorder the terms:

(-5 + y)(3 + 2y) = 0

Multiply (-5 + y) * (3 + 2y)

(-5(3 + 2y) + y(3 + 2y)) = 0

((3 * -5 + 2y * -5) + y(3 + 2y)) = 0

((-15 + -10y) + y(3 + 2y)) = 0

(-15 + -10y + (3 * y + 2y * y)) = 0

(-15 + -10y + (3y + 2y2)) = 0

Combine like terms: -10y + 3y = -7y

(-15 + -7y + 2y2) = 0

Solving

-15 + -7y + 2y2 = 0

Solving for variable 'y'.

Factor a trinomial.

(-3 + -2y)(5 + -1y) = 0

A contractor is required by a county planning department to submit 1, 2, 3, 4, or 5 forms (depending on the nature of the project) when applying for a building permit. Let y denote the number of forms required for an application, and suppose the mass function is given by p(y) 5 cy for y 5 1, 2, 3, 4, or 5. Determine the value of c, as well as the long-run proportion of applications that require at most three forms and the long-run proportion that require between two and four forms, inclusive.

Answers

Answer:

[tex](a)\ c = \frac{1}{15}[/tex]

[tex](b)\ 40\%[/tex]

[tex](c)\ 60\%[/tex]

Step-by-step explanation:

The given parameters can be represented as:

[tex]P_Y(y) \ge 0, y =1,2,3,4,5[/tex]

[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]

Solving (a): The value of c

To do this, we make use of the following rule;

[tex]\sum\limit^5_{y=1}P_Y(y_i) = 1[/tex]

Given that:

[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]

This is translated to:

[tex]c*1 + c * 2 + c * 3 + c * 4 + c * 5 = 1[/tex]

[tex]c + 2c + 3c + 4c + 5c = 1[/tex]

[tex]15c = 1[/tex]

Solve for c

[tex]c = \frac{1}{15}[/tex]

(b) The proportions of applications that requires at most 3 forms

This implies that: y = 1,2,3

So, we make use of:

[tex]P(Y \le 3) = P(Y=1) + P(y=2) + P(Y=3)[/tex]

Recall that:

[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]

Substitute [tex]c = \frac{1}{15}[/tex]

[tex]P_y(y) =\frac{1}{15}y[/tex]

So:

[tex]P(Y \le 3) = P(Y=1) + P(y=2) + P(Y=3)[/tex]

[tex]P(Y\le 3) = \frac{1}{15} * 1 +\frac{1}{15} * 2 +\frac{1}{15} * 3[/tex]

[tex]P(Y\le 3) = \frac{1}{15} +\frac{2}{15} +\frac{3}{15}[/tex]

Take LCM

[tex]P(Y\le 3) = \frac{1+2+3}{15}[/tex]

[tex]P(Y\le 3) = \frac{6}{15}[/tex]

[tex]P(Y\le 3) = 0.4[/tex]

Express as percentage

[tex]P(Y\le 3) = 0.4*100\%[/tex]

[tex]P(Y\le 3) = 40\%[/tex]

(c) The proportions of applications that requires between 2 and 4 forms (inclusive)

This implies that: y = 2,3,4

So, we make use of:

[tex]P(2 \le Y \le 4) = P(Y=2) + P(Y=3) + P(Y=4)[/tex]

[tex]P(2 \le Y \le 4) = 2 * \frac{1}{15} + 3 * \frac{1}{15} + 4 * \frac{1}{15}[/tex]

[tex]P(2 \le Y \le 4) = \frac{2}{15} + \frac{3}{15} + \frac{4}{15}[/tex]

Take LCM

[tex]P(2 \le Y \le 4) = \frac{2+3+4}{15}[/tex]

[tex]P(2 \le Y \le 4) = \frac{9}{15}[/tex]

[tex]P(2 \le Y \le 4) = 0.6[/tex]

Express as percentage

[tex]P(2 \le Y \le 4) = 0.6 * 100\%[/tex]

[tex]P(2 \le Y \le 4) = 60\%[/tex]

At Ralphs Italian Ices, 145 sundaes were sold in June. Sales were up 23% in July, How many sundaes were sold in July?

Answers

178 sundaes were sold in July.

To calculate a percentage, we convert to a decimal by dividing by 100. So 23% = 0.23

145 x 0.23 = 33.35 This is how many more sundaes were sold in July than June. We need to add the 145 sold in June to the increased number to find July’s total.
145 + 33.35 = 178.35

You can’t sell .035/ roughly a third of a sundae, so we round to the whole number.
