Answer:

SA = 788cm^2

Step-by-step explanation:

pink one:

length- 5

width- 6

height- 20

surface area- 500

purple one:

length- 4

width- 6

height- 12

surface area- 288

total surface area:

500 + 288 = 788

SA = 788cm^2

GOOD LUCK!!!! You'll do amazing <3

The total surface area of the composite figure will be 788 cm².

The total area occupied by an object's surface is referred to as its surface area. Varying 3D forms have different surface areas in geometry, which may be simply estimated using calculations.

The given pink cuboid has :

The length = 5

The width = 6

The height = 20

The surface area of pink cuboid = 500 cm²

The given purple cuboid has :

The length = 6

The width = 4

The height = 12

The surface area of purple cuboid = 288 cm²

Total surface area = The surface area of pink cuboid + The surface area of purple cuboid

Total surface area = 500 + 288 = 788 cm²

SA = 788 cm²

Thus, the total surface area of the composite figure will be 788 cm².

The daffodils flower Pate needs is 8, total number of flower when rose is 2, is 18 and the carnations to be needed for decoration is 15.

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

Pete is making decorations for a dinner party. The instructions tell him to use 9 flowers for a medium-sized decoration which has 2 lilies, 1 rose, 3 carnations, 2 daffodils and 1 iris.

The ratio of daffodils to total flower is,

n=2/9.

To make a large decoration, Pete uses 36 flowers. Let suppose the daffodils flower he needs for this is x. Thus,

x=36*(2/9)

x=4*2

x=8

The rose flower is increased from 1 to 2. Thus, the total number of flower also be twice for decoration.

Flower=2*9

Flower=18

Now Pete uses 10 lilies instead of 2 which is 5 times the medium-sized decoration. Thus, the carnations to be needed is,

Carnations=3*5

Carnations=15

Hence, the daffodils flower Pate needs is 8, total number of flower when rose is 2, is 18 and the carnations to be needed for decoration is 15.

Answer:

12^2 + 15^2 = 18^2

Step-by-step explanation:

If we have 3 sides of a triangle we can use the Pythagorean theorem to determine if the triangle is a right triangle

a^2 + b^2 = c^2

12^2 + 15^2 = 18^2

If this is true, then the triangle is a right triangle

Answer:

4a) $26.5 because if x represents how many feet then the slope would be the price of one glulam beam.

4b) $63,600

Step-by-step explanation:

To find the answer to 4b we need to alter the equation we were given. Since x represents how many feet we buy we put 2400 in place of x.

y = 26.5 x 2,400

and we simply solve from here

y = 63,600

So, 63,600 is how much we would be spending for 2400 feet of beams. Hope this helps!!

Using proportions, it is found that the average waste produced by each plant on a monthly basis is of 0.8 tons per month.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, there is a period of 60 x 12 = 720 months, with 104 plants, and 60,000 tons of waste were produced, hence the average is given by:

A = 60000/(720 x 104) = 0.8 tons per month.

By using concepts of logarithms and powers, the concentration of hydrogen ions in a volume of a liter of a sports drink with a pH of 2.5.

Logarithms are trascendental equations, that is, expression that cannot be described in terms of algebraic expressions. In this question we need to solve for the hydrogen ion concentration:

pH = log (1/[H⁺])

[tex]10^{pH} = \frac{1}{[H^{+}]}[/tex]

[tex][H^{+}] = 10^{-pH}[/tex]

[tex][H^{+}] = 10^{-2.5}[/tex]

Answer:

D

Step-by-step explanation:

when x = 0, y = 40

therefore you can pick either A or D only.

while x increases, y decreases, that's negative relation

so, answer is D

Answer:

Option D

Step-by-step explanation:

y = mx + b

b is the y - intercept (when x = 0):

this graph doesn't show any negative values on the axis so options B and C can't be true since it they have - 40 when its positive 40

y = mx + 40

The dot association is going downwards, the y values are getting smaller

making this a negative association leaving on ly option d true

The sum of the finite arithmetic series of  26 + 29 + 32 + 35 + 38 + 41 + 44 is 245. Arithmetic series is a sequence of number such that the difference between any term and the previous term is a constant number. When we sum a finite number of terms in the arithmetic series, we get the finite arithmetic series.
