The Nut Shoppe sells walnuts for $4.00 a pound and cashews for $7.00 a pound. How many pounds of cashews should be mixed with 10

Anton [14]

Answer: He sold 10 pounds of cashews .

Step-by-step explanation:

Since we have given that

Selling price of walnuts = $4.00 a pound

Selling price of cashews = $7.00 a pound

Number of pounds of walnuts = 10

Let number of pounds of cashew be x

Total price at which he sold a mixture = $5.50

According to question,

$10\times 4+x\times 7=(10+x)\times 5.50\\\\40+7x=55+5.5x\\\\7x-5.5x=55-40\\\\1.5x=15\\\\x=\frac{15}{1.5}\\\\x=10$

Hence, he sold 10 pounds of cashews .

Help me please- thank you

Answer:

y=-8/5x+4

Step-by-step explanation:

The slope of perpendicular lines is the opposite reciprocal of the original equation.

To get the opposite reciprocal, flip the fraction and use the opposite sign.

Here, the slope is -8/5 because that is the opposite of 5/8.

To get the equation of the line, use point-slope and then distribute to get the equation in y=mx+b format.

Point slope: y-y1=m(x-x1). Use the coordinate (5,-4) in the equation.

y+4=-8/5(x-5)

Multiply (x-5) by -8/5 and simplify.

y+4=-8/5x+8

y=-8/5x+4

Ms. galendez's backyard is a rectangle whose length is twice the width. if the perimeter is 720 ft, what are the dimensions of h

Talja [164]

Answer:

120ft and 240ft

Step-by-step explanation:

720 = 2L + 2W

Since L = 2W, we get

720 = 2(2W) + 2W

6W = 720

W = 120

L = 2W = 2(120) = 240

The dimensions of the yard are 120 feet and 240 feet

A person is standing 50 ft from a statue. The person looks up at an angle of elevation of

Alekssandra [29.7K]

Answer:

The height of the statue is <u>21.4 feet.</u>

Step-by-step explanation:

Given:

Distance of the person from the statue = 50 ft

Angle of elevation of the top of statue = 16°

Angle of depression of the bottom of statue = 8°

The diagram is drawn below.

In triangle ABC:

BC = 50 ft, ∠ABC = 16°

Using trigonometric formula;

$\tan(16)=\frac{y}{50}$

$y=50\tan(16)$

$y=14.337\ ft$

Now, let us determine the height of man, 'x'.

Consider triangle BDE.

ED = 50 ft, ∠BDE = 8°

Using trigonometric formula;

$\tan(8)=\frac{x}{50}\\\\x=50\tan(8)\\\\x=7.027\ ft$

Now, from the diagram, it is clear that, height of statue is given as:

$H=x+y=14.337+7.027=21.36\ ft\approx=21.4\ ft(Nearest\ tenth)$

Now;

Unknown:

cost per pound of pasta

Solution:

To find the cost per pound of pasta;

Cost per pound of pasta = $\frac{cost of pasta}{number of pasta}$

Cost per pound of pasta = $\frac{12}{8}$ = $1.5/pound
