Answer:

5/2 kg

Step-by-step explanation:

The ratio here is 2:6.  2 plus 6 is 8.

Then (2/8) times 10 kg represents the amount of compost needed; that comes to 20/8 kg, or 10/4 kg, or 5/2 kg.

Gabriel should use 2.5 kilograms of compost to create a 10-kilogram mix that has a ratio of 2 parts compost to 6 parts potting soil.

Gabriel is making a mixture for a special plant which requires a ratio of 2 parts compost to 6 parts potting soil. He aims to make 10 kilograms of this mix in total. To calculate the amount of compost he should use, we first have to find the total number of parts in the mix:

Add the parts of compost to the parts of potting soil: 2 parts (compost) + 6 parts (soil) = 8 parts (total).

Determine the weight of each part: 10 kilograms (total mix) / 8 parts = 1.25 kilograms per part.

Multiply the weight of each part by the number of parts for compost: 1.25 kilograms per part × 2 parts (compost) = 2.5 kilograms of compost.

Therefore, Gabriel should use 2.5 kilograms of compost for his special plant mix.

Answer:

-4

Explanation:

The slope of the line intersects points that are 4 points below and one point to the right of the previous point. (-4/1) = -4

Answer:

-4

Step-by-step explanation:

The line goes through the points (-1,3) and (0,-1)

We can find the slope by using the formula

m = (y2-y1)/(x2-x1)

   = (-1-3)/(0--1)

  = (-1-3)/(0+1)

   = -4/1

   = -4

The slope is 4/6 because its going up by 4 over by 6 .hope this helps

Answer:

slope = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (6, 0) ← 2 points on the line

m = [tex]\frac{0+4}{6-0}[/tex] = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

When a parabola has the form  [tex]y=ax^2+bx+c[/tex] , It is vertical (opens up or down).

Because the variable "x" is squared.

If  "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.

In this case you have the quadratic function:

[tex]f(x) = 2x^2+5x-4[/tex]

Which can be rewritten as:

 [tex]y = 2x^2+5x-4[/tex]

Therefore, it is vertical, because it has the form:  [tex]y=ax^2+bx+c[/tex]

You can observe that the value of "a" is:

[tex]a=2[/tex]

Then, since "a" is positive, the parabola opens up.

[tex] \frac{4x + 12}{32} = \frac{15}{8} \\ ( = )32x + 96 = 480 \\ ( = )x = 12[/tex]

Answer:

x = 12

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{4x+12}{15}[/tex] = [tex]\frac{32}{8}[/tex] = 4, thus

4x + 12 = 4 × 15 = 60 ( subtract 12 from both sides )

4x = 48 ( divide both sides by 4 )

x = 12

Answer:

[tex]\frac{1}{16}[/tex] Is the chance of the colours matching.

Step-by-step explanation:

The possibility of the spinner landing on an orange side is [tex]\frac{1}{4}[/tex]

and the possibility of the marble being orange is [tex]\frac{1}{4}[/tex] in this case you have to remember, in the fraction, you have 4 possibilities and 1 desirable outcome, when you have two dependant possibilities you have to multiply them:

[tex]\frac{1}{4} * \frac{1}{4}[/tex]

And the result of that multipliction is [tex]\frac{1}{16}[/tex] which is the probability of the marble and the spiner colours matching.

Answer:

May 6

Step-by-step explanation:

20 x 2 = 40 40 x 2 = 80 80 x 2 = 160 x 2 = 320 320 x 2 = 640 after 5 days on may 6 it will surpass 500 meters.

The oil spill, doubling in size each day from an initial 20 square meters, will exceed 500 square meters on the 6th of May.

Based on the information provided, let's calculate how long it will take for the oil spill to exceed 500 square meters if it doubles in size each day starting from an initial size of 20 square meters. On May 1, the spill is 20 square meters. On May 2, it would be 40 square meters (20*2). If we continue this pattern, we can find the day the spillage area will exceed 500 square meters:

Therefore, the area of the oil spill exceeds 500 square meters on May 6.

Gabriel Mouton

Early development. Most historians agree that Gabriel Mouton, the vicar of St. Paul's Church in Lyons, France, is the “founding father” of the metric system. He proposed a decimal system of measurement in 1670.

Answer:

i)

The confidence interval is at 90%

ii)

The margin of error is 5%

iii)

The 90% confidence interval is (70%, 80%)

iv)

We are 90% confident that the average score of seniors in the field test is between 70% and 80%.

Step-by-step explanation:

i)

The confidence interval is at 90%

We are informed that the exam creator claims that on this particular exam, nine times out of ten, seniors will have an average score within 5% of 75%. This implies that we are 9 times out of 10 confident that seniors will have an average score within 5% of 75%.

The level of confidence is thus;

(9/10)*100 = 90%

ii)

The margin of error is 5% or equivalently 0.05

We are informed that the exam creator claims that on the same exam, nine times out of ten, seniors will have an average score within 5% of 75%.

Since the average score is within 5%, the margin of error is 5%

iii)

A confidence interval is calculated using the formula;

point estimate ± margin of error

Our point estimate is 75%

Our margin of error is 5%

The 90% confidence interval is thus;

75% ± 5% = (70%, 80%)

iv)

The 90% confidence interval is interpreted as;

We are 90% confident that the average score of seniors in the field test is between 70% and 80%.

This is a confidence interval for the mean, the level of confidence is 90% and our confidence interval is (70%, 80%).

Answer:

  ∠FIG = (47/2)° = 23.5° . . . . . rounds to 24°

Step-by-step explanation:

The value of x can be found from ...

  72 = 3x+3 . . . . the central angle and the arc measure are the same

  24 = x+1 . . . . . divide by 3

  23 = x . . . . . . . .subtract 1

The measure of ∠FIG is half the difference of the arc measures FG and RZ, so is ...

  m∠FIG = (1/2)(3x+3 - (x+2)) = (1/2)(2x +1) = x +1/2

  m∠FIG = 23 1/2 . . . . degrees

Abra is the best shooter because 9/10 is almost a 1 where 3/4 is .75.

The area of one face would he h^2.

There are 6 faces, so the total surface area would be h^2 x 6

Replace total surface area with 2.16, so you now have:

2.16 = h^2 x 6

Now we can solve for h.

Divide both sides by 6:

h^2 = 2.16/6

Take the square root of both sides:

h = √2.16/6

To simplify 12/24 you have to find a common multiple. a common multiple is 12. you see how many times 12 goes into each number. 12/12 is 1 and 24/12 is to. therefore 1/2 is the correct answer

The ratio of multiplication problems to division problems on the given math test is 1/2.

To answer the question, you need to set up a ratio between the number of multiplication problems and the number of division problems. In this case, you have 12 multiplication problems and 24 division problems.

The ratio would be set up as 12 (multiplication problems) to 24 (division problems), written as 12/24 in fractional form. However, we need to reduce this to its simplest form. Both 12 and 24 can be divided by 12, simplifying the ratio to its simplest form of 1/2.

Therefore, the ratio of multiplication problems to division problems on this math test is 1/2.

Given,

Responses on first day or original responses = 80

While responses on second day or final responses = 180,

Thus, the percentage increase in the responses

[tex]=\frac{\text{ final responses- original responses}}{\text{original responses}}\times 100[/tex]

Answer:

Your answer is 7.0

Step-by-step explanation:

If the circles are congruent and RQ measures 35.6, then so does CB.  That means that half of it (the radius XD which measures 26 cuts the length of CB in half) is 17.8.  If the base of that right triangle is 17.8 and the hypotenuse is 26, then Pythagorean's Theorem tells us that the height of the triangle is 18.95151709.  Subtract that from the radius length of 26 and you'll have the length of DE

The value of length ED would be, 7.0

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

⊙X≅⊙Y

And, Length of RQ = 35.6

Now, We get;

⇒ CB = RQ = 35.6

Hence, EB = 1/2CB

                 = 1/2 (35.6)

                 = 17.8

Applying Pythagoras theorem,

⇒ XE² = XB² - EB²

⇒ XE² = 26² - 17.8²

⇒ XE² = 19

Thus, The length of ED is,

⇒ ED = XD - XE

⇒ ED = 26 - 19

⇒ ED = 7.0

Therefore, The value of length ED would be, 7.0
