Answer:

M=1

Step-by-step explanation:

m-1/4=3/4 add 1/4 to both sides and you get m=1

Answer:

M = 1

Step-by-step explanation:

M-1/4=3/4

add 1/4 to both sides of the equation:

M - 1/4 + 1/4 = 3/4 + 1/4

simplify:

M = 1

Answer:

Sophie has to work 18 hours to buy the sneakers.

Step-by-step explanation:

Since Sophie earns $ 12.80 per hour babysitting, and she has to repay a loan to her parents in the amount of $ 100, and after repaying the loan, she wants to have at least enough money to buy herself a pair of sneakers costing $ 130.40, for write an inequality modeling the number of hours, X, Sophie needs to work to have enough money to buy the sneakers, the following mathematical reasoning must be carried out:

12.80X = 100 + 130.40

12.80X = 230.4

X = 230.4 / 12.8

X = 18

So Sophie has to work 18 hours to buy the sneakers.

Answer: 49

Step-by-step explanation:

The missing constant term in the perfect square is 49.

x^2 + 14x + 49

We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.

Answer:

Distance between cities Y and Z = 26 miles

Step-by-step explanation:

From the picture attached,

Length of XY = 10 mi

Length of XZ = 24 mi

By applying Pythagoras theorem in the given right triangle XYZ,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

YZ² = XY² + XZ²

      = 10² + 24²

      = 100 + 576

      = 676

YZ = √676

     = 26 mi

Therefore, distance between cities Y and Z is 26 mi.

Answer:

The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.

Step-by-step explanation:

We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.

Let us find the sample score that corresponds to z-score of bottom 4%.

From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.

Upon substituting these values in z-score formula we will get our sample scores (x) as:

Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.

Now let us find sample score corresponding to z-score of 1.75 as upper limit.

Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected

Answer:

By applying Pythagorean's theorem, the hypotenuse of this triangle is equal to: D. √32 inches..

Given the following data:

Adjacent side = 4 inches

Opposite side = 4 inches.

In order to calculate the hypotenuse of this triangle, we would apply Pythagorean theorem.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

Substituting the given parameters into the formula, we have;

c² = 4² + 4²

c² = 16 + 16

c² = 32

c = √32 inches.

Answer: Loss, 200 Rs

Step-by-step explanation:

Given

Sharad bought  a quintal of onion i.e. [tex]1000\ kg[/tex] for [tex]Rs.\ 2000[/tex]

So, the cost price of onion is

[tex]\Rightarrow \dfrac{2000}{100}=20\ \text{Rs per kg}[/tex]

He sells it at [tex]18\ \text{Rs. per kg}[/tex]

Here, the Selling price is less than the cost price

So, he incurs a loss of [tex]2\ \text{Rs per kg}[/tex]

For a quintal it is

[tex]\Rightarrow 2\times 100=200\ \text{Rs}[/tex]

[tex]\Rightarrow \text{Loss }\ \%=\dfrac{C.P.-S.P.}{C.P.}\times 100\\\\\Rightarrow \text{Loss }\ \%=\dfrac{20-18}{20}\times 100=10\%[/tex]

Answer:

2 more people each day.

Step-by-step explanation:

We are given the following relation:

[tex]d = \frac{192}{n}[/tex]

In which d is the number of days that will take to run a marketing campaign with n people.

Alex’s company will take 32 days to run the campaign.

So the number of people in his campaign is given by:

[tex]32 = \frac{192}{n}[/tex]

[tex]32n = 192[/tex]

[tex]n = \frac{192}{32}[/tex]

[tex]n = 6[/tex]

Shay’s company will take 24 days to run the campaign.

So the number of people in her campaign is given by:

[tex]24 = \frac{192}{n}[/tex]

[tex]24n = 192[/tex]

[tex]n = \frac{192}{24}[/tex]

[tex]n = 8[/tex]

Shays company will have to use more people each day than alex’s company. how many more?

8 - 6 = 2
