Answer: 85.8g

Step-by-step explanation:

From the question, we are informed that 46.8g of sugar is needed to make 6 cakes. Therefore, the amount of sugar needed to make 1 cake will be:

= 46.8/6

= 7.8kg

Then, the amount of sugar needed to make 11 cakes will be:

= 7.8 × 11

= 85.8g

answer : here cp is greater than sp so it is loss

Answer:

if these expression represent side lengths, then you simply add those three expressions, and that's the perimeter.

Step-by-step explanation:

I explore this idea a bit. obviously x < 5 (because 5-x has to be positive.

2x-5 > 0 is a requirement, also, so x > 2.5 is required.

Answer:

Your Answer will be 129, not a fraction. It will be a whole number

Step-by-step explanation:

43 x 6 = 258

258 / 2 = 129

Answer:

[tex]x = 27[/tex]

Step-by-step explanation:

A shape exterior angles add up to 360.

All of these angles are exterior angles so we can add up all of them to and set it equal to 360 to find x.

[tex]3x + 4x + 2x + 40 + x + 50[/tex]

[tex]10x + 90 = 360[/tex]

[tex]10x = 270[/tex]

[tex]x = 27[/tex]

C is the correct answer

Hi there!

c=11 2/3

1.Convert 5 5/6 into mixed number:

[tex]5 \frac{5}{6}=\frac{35}{6}[/tex]

2.Convert 2 into fraction term:

[tex]2=\frac{2}{1}[/tex]

3.Convert both fraction into same denominator:

[tex]\frac{35}{6}=\frac{35}{6}[/tex]

[tex]\frac{2}{1}=\frac{12}{6}[/tex]

4.Multiply the two terms:

[tex]\frac{35}{6}[/tex]·[tex]\frac{12}{6}=\frac{70}{6}[/tex]

5.Simplfly the fraction term:

[tex]\frac{70}{6}=\frac{35}{3}[/tex]

[tex]\frac{35}{3}=11 \frac{2}{3}[/tex]

Therefore, c=11 2/3.

Step-by-step explanation:

3x²y³·x⁴y = 3x²x⁴y³y = 3x²⁺⁴y³⁺¹ = 3x⁶y⁴

Answer:

NR = 12

Step-by-step explanation:

Given that both trjangles are similar, therefore, it follows that their corresponding side lengths would be proportional to each other. Thus:

[tex] \frac{40}{8} = \frac{60}{2x - 2} [/tex]

[tex] 5 = \frac{60}{2x - 2} [/tex]

Cross multiply

[tex] 5(2x - 2) = 60 [/tex]

[tex] 10x - 10 = 60 [/tex]

[tex] 10x = 60 + 10 [/tex] (addition property of equality)

[tex] 10x = 70 [/tex]

Divide both sides by 10

x = 7

✔️NR = 2x - 2

Plug in the value of x

NR = 2(7) - 2 = 14 - 2

NR = 12

I take it as you want to learn about the formula.

The quadratic formula is a formula where you can solve x for any quadratic equation in form  ax^2+bx+c=0.

The formula is x= [tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex].

The +- means + or - for the 2 solution in each equation.

*All above information is what you need to know about the quadratic formula and solve for answer, but I will go a step further in my answer to prove the quadratic formula always work.

[tex]0=ax^2+bx+c[/tex]

[tex]0=(ax+\frac{b}{2})^2-\frac{b^2}{4}+c[/tex] (This step is completing the square)

[tex](ax+\frac{b}{2})^2=\frac{b^2}{4}-c[/tex]

[tex](2ax+b)^2=b^2-4ac[/tex]

[tex]2ax+b=+or-\sqrt{b^2-4ac}[/tex]

[tex]2ax=-b+ or -\sqrt{b^2-4ac}[/tex]

[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

This is my way of proving this formula although there are many other ways to do it too, if there is any questions, feel free to ask me in the comment :-).

Answer:

the answer is 6.75

Step-by-step explanation:

12 x 5 = 60 60 = 1 hour so 1.35 x 5 = 6.75

The running speed is 8.1 miles/ second.

Speed is the rate at which something is covering a distance in a fixed period of time.

It is measured in miles/ min or miles/sec.

It is given that

Speed = 1.35 miles per minute

1 minute = (1/60) hour

Therefore the speed = 1.35 *60

Speed = 8.1 miles/second

Therefore the speed is 8.1 miles/ second.

Answer:

Trapezoid = 24 grams

Step-by-step explanation:

Trapezoid = 3 triangles

x = 3 · 8

x = 24

Answer:

$0.98

Step-by-step explanation:

Given data

Cost of sinuses apples = $9.8 for 10 pound

We want to find the cost per pound

Hence

if 10 pounds cost $9.8

  1 pound will cost x

cross multiply

x= 9.8/10

x= $0.98

Hence a pound will cost $0.98

Answer:

[tex]y = 4.2x[/tex] is a linear equation.

Step-by-step explanation:

The slope-intercept form of the line or linear equation is of the form

[tex]y = mx+b[/tex]

where

[tex]m[/tex] represents the slope

represents is the y-intercept

In our case, the given equation is

[tex]y = 4.2x[/tex]

comparing with the slope-intercept form of the line or linear equation

[tex]y = mx+b[/tex]

Thus,

As the equation [tex]y = 4.2x[/tex] resembles the linear equation [tex]y = mx+b[/tex] of the line.

Hence, [tex]y = 4.2x[/tex] is a linear equation.

Please also check the attached graph of the linear equation  [tex]y = 4.2x[/tex] .

Important Tips:

∴ [tex]y = 4.2x[/tex] is a linear equation.

Answer: P = 2716.3448786 or about 2700

Step-by-step explanation:

The amount that need to invest, to the nearest hundred dollar is to be considered as the 2,700.

Since

The interest rate be like = 1.5% = 1.5% / 4 = 0.38%

The time period = 13 * 4 = 52

The future value = $3,300

The PMT is = $0

Now the following formula is used;

So,

= -PV(RATE,NPER,PMT,FV,TYPE)

After applying it, the present value should be $2,700
