Mark is buying different nuts to make a mixed nut platter to serve at a party. He buys 1.2 kilograms of peanuts, 300 grams of almonds and 40 dekagrams of cashews. What is the total weight in grams of the nuts he purchased? Enter only the number. Do not include unit

Answers

Answer:

1900

Step-by-step explanation:

1 kg = 1000g

1.2kg = x

1 kgx = 1200 kg.g

1kg. 1kg

x = 1200 g

1 decagram = 10g

40 decagram = x

1 dg.x = 400 dg.g

1 dg. 1 dg

x = 400g

so the total= 1200g +300 + 400g=1900g

without the unit = 1900

3 cos 2x + Sinx = 1 for
0° ≤x ≤ 360​

Answers

Answer:

x = 41.81°, 138.19°, 210°, 330°

Explanation:

3cos(2x) + sin(x) = 1

subtract one from both sides

→ 3cos(2x) + sin(x) − 1 = 0

rewrite using trigonometry identities

→ 2 + sin(x) − 6sin²(x) = 0

solve x by substitution

f(x) = 2 + sin(x) − 6sin²(x)

= 2 + 4sin(x) - 3sin(x) − 6sin²(x)

= −2sinx(3sinx −2) − (3sinx−2)

= (3sinx −2)(−2sinx−1)

= −(3sinx −2)(2sinx+1)

f(x) = 2 + sin(x) − 6sin²(x) = 0

= −(3sinx −2)(2sinx+1) = 0

(3sinx −2) = 0 (2sinx+1) = 0

→sinx = 2/3 →sinx = −1/2

x = 41.81°, 138.19° x = 210°, 330°

How to factorize an Algebraic Expression?

To factorize an algebraic expression, it means that the highest common factors of the terms of the specific algebraic expression are determined and then we group the terms accordingly.

We are given the algebraic expression as;

6a – 4(2a + 3)

Multiplying the bracket out gives us;

6a - 4(2a) - 4(3)

= 6a - 8a - 12

= -2a - 12

Now, the highest common factor of the expression is 2 and so we have;

-2(a + 6)

24n + 40d = 162

8n + 8d = 38

-24n - 24d = -114

24n + 40d = 162

-24n - 24d = -114

It is B as 5 is the y intercept in the equation. Checked with a graphing calculator. B is the answer

The correct statement for the equation of the line is the line passes through the ordered pair (0,5) and has a slope of 3.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Compare the given equation of the line y = 3x + 5 with the general equation.

y = mx + c

y = 3x + 5

The slope, m = 3

y-intercept = 5

Answers

Answer:

Step-by-step explanation:

Perimeter of the composite shape = ½ of the circumference of a circle + perimeter of a rectangle - Length of the rectangle

= ½*2πr + 2(L + W) - L

Where,

r = 8

π = 3.14

L = 16

W = 12

Perimeter of the composite shape = ½(2*3.14*8) + 2(16 + 12) - 16

= 25.12 + 56 - 16

Perimeter of the composite figure = 65.12 inches

Area of the composite figure = ½(πr²) + L*W

= ½(3.14*8²) + 16*12

= 100.48 + 192

Area = 292.48 square inches

They do not believe that Apollo is Phathons father or that Apollo makes the sun rise and set. In order to prove Phathon s friends wrong, Apollo hesitantly gives Phathon his chariot and horses. Apollo hurried to give directions. You have never driven my chariot before. You must make the horsesstay on the path. If you are too low, you will scorch the earth. I know, Father. Now watch me take off! shouted Phathon. Dawn stepped back and released her grip on the horses bridles. The horses pawed the ground and snorted with excitement. The sky begged for Dawns light, so she ran toward the horizon in her glowing gown to make the darkness fade. As Phathon was about to ascend, Apollo grabbed his arm and said, Please listen to me! If you go too high, you will warm the cold depths of the heavens, and the Bear or Snake or Scorpion will come alive! Phathon just laughed. My friends are waiting. Ive got to go! he shouted. With that, the chariot was off. It was a wild ride. Hour and Day were unruly and difficult to control. Phathon did not have his fathers strong arms or years of experience. The horses wove from side to side and bobbed up and down through the heavens, hitting everything in their way. The sun bounced along behind the chariot like a basketball. It grazed the stars and skidded along mountaintops, leaving charred remains behind. Phathons friends ran for cover as they watched the spectacle. Just as his father had warned him, the figures in the sky began to move. Suddenly the Scorpion lunged toward him, but Phathon ducked out of the way in time. The Snake lashed out and bit a wheel off the chariot. Apollo, witnessing the destruction, dashed up toward the heavens, but he was too late! The Bear had stirred from his icy hibernation and grabbed Phathon before his father could reach him. Apollo grabbed the reins and finally regained control of Hour and Day, but it was years before the earths mountaintops were white with snow again. The scorched areas became deserts where very little would grow. Phathon became a part of the constellations alongside the Bear, where his father could regretfully keep an eye on him.
