The total weight of the shape blocks on both sides of Michael's pan balance equals 30 grams. Circles weigh 5 grams, squares weigh 10 grams, and triangles weigh 3 grams. The right side has a circle and a square. How many triangles are on the left side?

Answers

Answer 1

Answer:

There would be 5 triangles on the other side

Step-by-step explanation:

If the right side has 1 circle and 1 square, that would mean that there is 5g+10g=15g weight on the right side

In total, there is 30g, and we already have 15

We can use the equation 15+3x=30, and by solving, the answer would be 5 triangles.

Hope this helps!

3c+6=18 how do you work this problem?

Answers

Answer:

c = 4

Step-by-step explanation:

Simplifying

3c + 6 = 18

Reorder the terms:

6 + 3c = 18

Solving

6 + 3c = 18

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + 3c = 18 + -6

Combine like terms: 6 + -6 = 0

0 + 3c = 18 + -6

3c = 18 + -6

Combine like terms: 18 + -6 = 12

3c = 12

Divide each side by '3'.

c = 4

Simplifying

c = 4

Answer:

Step-by-step explanation:

subtract six from both sides

3c+6-6=18-6

simplify

3c=12

divide both sides by 3

3c/3 =12/3

c=4

Answers

Answer:

106°

Step-by-step explanation:

By exterior angle theorem:

[tex]m \angle \: 1 = 62 \degree + 44 \degree \\ \\ m \angle \: 1 = 106 \degree[/tex]

Step-by-step explanation:

Let the unknown angle in the triangle be x.

x + 44 + 62 = 180(sum of angles in a triangle)

x + 106 = 180

x = 180 - 106

x = 74

Angle 1 + x = 180 (Sum of angles on the same straight line)

angle 1 + 74 = 180

Angle 1 = 180 - 74

= 106

A new field has a perimeter of 220 m and a width of 62 m. A bag of canola seed will cover 185 m2 of ground. How many bags of canola seed are needed to seed the new field?
52
16
53
17

Answers

Answer:

17

Step-by-step explanation:

Assuming the field is a rectangle, the perimeter is found through the equation:

[tex]P = 2l + 2w[/tex]

Since we know the perimeter and width, we can substitute and solve for the length.

[tex](220) = 2l + 2(62)\\220 = 2l + 124\\96 = 2l\\l = 48\\[/tex]

Using the length and width, we can find the area.

[tex]A = lw\\A = (48)(62)\\A = 2976[/tex]

The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.

[tex]n = 2976 / 185\\n = 16.09[/tex]

Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.

find the gradient of the line segement between the points (0,-6) and (2,-16)

Answers

answer = 5

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:

A line is increasing, and goes upwards from left to right when m > 0

A line is decreasing, and goes downwards from left to right when m < 0

A line has a constant slope, and is horizontal when m = 0

A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.

Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:

m =

y2 - y1

x2 - x1

The ceiling of Katie’s living room is a square that is 15 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Katie can buy rolls that each contain 20 ft of crepe paper. What is the minimum number of rolls she should buy? Show your work.

Answers

Answer:

6 rolls because the total perimeter is 102 ft and five rolls is only 100 feet. So she needs 6 rolls.

Step-by-step explanation:

to find perimeter, add up all the side lengths.

so 15*4 (it's easier than 15+15+15...)

60 ft.

now we have to use Pythagorean's Theorum to find corner to corner.

so [tex]a^2+b^2=c^2[/tex]

we have a and b

[tex]15^2+15^2=c^2[/tex]

do the math...

225+225= 450

square root of 450=

21.213

double that because it's used twice (corner to corner and corner to corner)

42.426

now add it all up

42.426 + 60 = 102.426

we can round

102

20*5 = 100

so she needs 6

MY ORIGINAL ERROR WAS 5, BUT 5 TIMES 20 IS ONLY 80, SO THEREFORE 6 IS REQUIRED SO THERE IS ENOUGH TO COVER 102.

Answer:

Katie needs 6 crepe rolls.

Step-by-step explanation:

Hello!

Katie originally needed ~5.1 crepe rolls, but since its a question on how many rolls she should by, she should get 6.

There are a couple of steps in order to solve this.
