Mrs kin picked some tomatoes from her garden. She use 5/9 of her tomatoes to make pasta sauce. Then she used 5/8 of the remainder to make a salad and saved the rest for the next day. What fraction of the tomatoes did mr kin saved

Answers

Answer:

1/6 of the tomatoes

Step-by-step explanation:

So first, after she uses 5/9 she has 1 - 5/9 = 4/9 of her tomatoes left. Then, she uses 5/8 of that 4/9 to make a salad, so she used 5/8 * 4/9 = 5/18 of her tomatoes overall.  That means that she has 4/9 - 5/18 = 8/18 - 5/18 = 3/18 = 1/6 of her tomatoes saved.

Simple math...

if the area of an equilateral triangle is 24 square root 3 metres square then its perimeter is?​

Answers

Answer:

6√24 or 29.39metres

Step-by-step explanation:

Area of a triangle is bh/2

The perimeter of an equilateral triangle is 3b

This equilateral triangle can be imagined as two adjoining 30-60-90 triangles. Together, their area is the given 24√3 m²

The base of the individual triangle is √24. The height is √24√3. Multiplying those factors, we get the given area, a proof of sorts, but mure importantly, we can calculate the length of the hypotenuse as 224.

sin(30°) = 0.5

√24/(0.5) = 2√24

That is the length of the side of the original equilateral triangle.

The perimeter is 3 times the length of the side:

(3)(2√24) = P

624 meters is the perimeter.

If f(x) = -2 and g(x) = 2x² + x-3, find (f +9)(x).

Answers

Answer:

(f + g)(x) = 2x² + x - 5

Step-by-step explanation:

Given

[tex]f(x) = -2[/tex]

[tex]g\left(x\right)\:=\:2x^2+\:x-3[/tex]

To determine

(f + 9)(x) = ?

Using the formula

(f + g)(x) = f(x) + g(x)

substituting f(x) = -2 and g(x) = 2x² + x - 3

             = -2 + 2x² + x - 3

             = 2x² + x - 5

Therefore, we conclude that:

(f + g)(x) = 2x² + x - 5

A concrete mixing machine weighing 800 pounds needs to be loaded with rocks and sand. Trucks carrying 120 pounds of sand
and 30 pounds of rocks will be used to load the machine. In order for the machine to function properly, the combined weight
of the machine and the mixing load cannot exceed 2,800 pounds.
Which inequality describes the restriction on truck loads, x, to ensure the mixing machine functions properly?
A. 120x+800 > 2,800
B. 150x + 800 > 2 2,800
C. 800x + 150 < 2,800
D. 150x+800 < 2,800

Answers

The inequality to ensure the mixing machine functions properly is,

D. 150x + 800 < 2800

What are inequalities and their types?

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

From the given information and the statement that the combined weight should not exceed  2800 pounds the inequality that represents the number of loads it can take  to ensure the mixing machine functions properly is,

150x + 800 < 2800.

What is the value of x in the equation below?
3(12x-24) = 16
A) 2
B) 6
C) 8
D) 10



ANSWER: B) 6

Answers

Answer:

3(12x - 24) = 16 (use the distributive property)

36x - 72 = 16  (add 72 to both sides to get the x-term alone)

36x = 88 (divide both sides by 36 to isolate x)

x = 2.4 (the four is repeating. that's the exact answer.)

I would say the answer is A because 2.4 is close to 2 than any of the other answers.

Sharon bought 6 new folders for $1.15 each and 15 pens that were priced at 5 for $4.75. What is the total amount she spent?

Answers

Answer:

$21.15

Step-by-step explanation:

6 x 1.15 = 6.9 (because we're working with money, we'll add a zero at the end for the ones place) = 6.90

15/5 = 3 then 3 x 4.75= 14.25

14.25 + 6.90 = 21.15

Hope this helped <3

Answer:

$21.15

Step-by-step explanation:

Total Folder Amount: $1.15 • 6 = $6.90

Total Pen Amount: $4.75 • 3* = $14.25

*She bought 15 pens. The pens were 5 pens for $4.75. 15÷5=3*

$14.25 + $6.90 = $21.15

Eric is a statistician-Viking. He walks into a tavern and makes three statements about the continuity correction. Which are true?
I. You can find single probabilities (such as x - 4) using the normal approximation to the binomial. Do this by finding the probability for the range from.5 below to .5 above the number. (For x 4 you'd find 3.5x 4.5.)
Il. Using the normal approximation, x 4 is the same as x4. Using the exact binomial, x <4 is not the same as x - 4
IlI. The continuity correction removes some of the error introduced when modeling a discrete distribution with a continuous one. The correction increases accuracy by acting as though a number occupies the interval from.5 below it to.5 above it.
