Answer:

(b) The number of pounds of berries each person would receive is [tex]1\frac{5}{8}[/tex]pounds.

Step-by-step explanation:

The amount of berries in first basket = 3 3/8 pounds

Now, [tex]3\frac{3}{8}  = 3+\frac{3}{8} = 3 + 0.375 = 3.375[/tex]

So, the amount of berries in first basket = 3.375 pounds

The amount of berries in second basket = 2 7/8 pounds

Now, [tex]2\frac{7}{8}  = 2+\frac{7}{8} = 2 + 0.875 = 2.875[/tex]

So, the amount of berries in second basket = 2.875 pounds

Now, the total berries = Berries in ( First + Second)  basket

                                      = 3.375 pounds +  2.875 pounds  

                                    = 6.25 pounds

So, the number of pounds each person would have = [tex]\frac{\textrm{Total weight of viable berries}}{\textrm{4}}  = \frac{6.25}{4} = 1.5625[/tex]

Now, [tex]1.5625 = 1 + 0.5625  = 1 + \frac{5625}{10000}  = 1 + \frac{5}{8}  = 1\frac{5}{8}[/tex]

So, the number of pounds of berries each person would receive is [tex]1\frac{5}{8}[/tex]pounds.

Answer:

∠A=67°

∠B=70°

∠C=43°

Step-by-step explanation:

The correct question in English is

Determines the measurement of each of the angles of the triangle ABC if it is known that A=(3x+1)°,B=(3x+4)° and C=(2x-1)°.

we know that

The measure of the interior angles in a triangle must be equal to 180 degrees

so

∠A+∠B+∠C=180°

substitute the given values

[tex](3x+1)\°+(3x+4)\°+(2x-1)\°=180\°[/tex]

solve for x

[tex](8x+4)\°=180\°[/tex]

[tex]8x=180-4[/tex]

[tex]x=22[/tex]

Find the measure of each angle

∠A=(3(22)+1)=67°

∠B=(3(22)+4)=70°

∠C=(2(22)-1)=43°

(C) 7/10 cup is the correct answer

Step-by-step explanation:

First of all we will calculate the 40% of grandmother's recipe then add it to the given flour in grandma's recipe

So,

The amount of flour in grandma's recipe = F_g = 1/2 cups

Calculating percentage

[tex]=40\%\ of\ \frac{1}{2}\\=\frac{40}{100}*\frac{1}{2}\\=\frac{2}{10}[/tex]

So Evelyn needs to add 2/10 cups more to the original quantity.

So,

Flour used by Evelyn:

[tex]=\frac{1}{2}+\frac{2}{10}\\\\=\frac{5+2}{10}\\\\=\frac{7}{10}\ cups[/tex]

Hence,

(C) 7/10 cup is the correct answer

Step-by-step explanation:

Answer:

two places to the left

Step-by-step explanation:

Answer:

See explanation

Step-by-step explanation:

Given

[tex](8x+12y)^2+(6x+9y)^2=(10x+15y)^2[/tex]

Note

[tex](8x+12y)^2=(4(2x+3y))^2=16(2x+3y)^2\\ \\(6x+9y)^2=(3(2x+3y))^2=9(2x+3y)^2\\ \\(10x+15y)^2=(5(2x+3y))^2=25(2x+3y)^2[/tex]

Since

[tex]16(2x+3y)^2+9(2x+3y)^2=(2x+3y)^2(16+9)=25(2x+3y)^2,[/tex]

this is an identity

Problem 1

A = 5! = 5*4*3*2*1 = 120 ways to arrange the math books

B = 4! = 4*3*2*1 = 24 ways to arrange the French books

C = 2! = 2*1 = 2 ways to arrange the biology books

D = 3! = 3*2*1 = 6 ways to arrange the three blocks of books, each block a different subject

E = A*B*C*D = 120*24*2*6 = 34560 different ways to arrange the books such that the subjects stick together

-------------

========================================

Problem 2

Group all the math books to form one "book". This is the same as taking out the 5 math books and replacing it with one single math book. This single math book acts as a placeholder for all of the five books together as one block.

We have

1 math "book"

4 French books

2 biology books

So there are 1+4+2 = 7 "books" total and

7! = 7*6*5*4*3*2*1 = 5040 different ways to arrange those "books"

Within the math block of books, there are 5! = 120 ways to arrange things.

So overall we have 120*5040 = 604800

Step-by-step explanation:

We note that 0.14 is easily divisible by 7, so we can do this using the distributive property:

  (-3 2/7)(0.14) = (-1)(3 + 2/7)(0.14)

  = (-1)(3×0.14 +2/7×0.14)

  = (-1)(0.42 +0.04)

  = -0.46 . . . . . decimal form

  = -46/100 . . . . place value

  = -23/50 . . . . remove common factor of 2; fraction form

The product is -0.46 or -23/50.

Answer:

The value of sin t is [tex]\frac{7}{25}[/tex]

Step-by-step explanation:

Given as :

cos (t) = [tex]\frac{24}{25}[/tex]

Since sin² t + cos² t = 1

So, sin² t = 1 - cos² t

or,  sin² t = 1 - ([tex]\frac{24}{25}[/tex])²

or,  sin² t = [tex]\frac{25^{2} - 24^{2} }{25^{2} }[/tex]

Or,  sin² t = [tex]\frac{625 - 576}{625}[/tex]

Or ,   sin² t = [tex]\frac{49}{625}[/tex]

Or, sin t = [tex]\sqrt{\frac{49}{625} }[/tex]

So, sin t = [tex]\frac{7}{25}[/tex]

Hence The value of sin t is [tex]\frac{7}{25}[/tex]   Answer

(11/4)x units

Step-by-step explanation:

for a rectangle,

perimeter = 2(length) + 2(width)

given:

length = x

width = (3/8)x

hence,

perimeter = 2(length) + 2(width)

perimeter = 2x + 2(3/8)x

perimeter = 2x + (3/4)x

perimeter = [2 + (3/4)]x

perimeter = (11/4)x

Final answer:

The sum of two positive numbers always has a positive sign, so the sum of 3/5 + 3/5 is positive.

Explanation:

The question what is the sign of 3/5 + 3/5 involves understanding the rules of addition for numbers with the same sign. According to the rules of addition:

When two positive numbers add, the answer has a +ve sign.

Since both fractions 3/5 and 3/5 are positive, their sum will also have a positive sign. Therefore, the sign of the sum 3/5 + 3/5 is +ve, which means the answer is also positive.

Answer:

The speed at which the satellite travel is 6.80 miles per second

Step-by-step explanation:

Given as :

The distance cover by satellites = 29 [tex]\frac{1}{2}[/tex]  miles

Or, The distance cover by satellites  = [tex]\frac{59}{2}[/tex] miles

The Time taken by satellite to travel with this speed = 4[tex]\frac{1}{3}[/tex] sec

Or, The Time taken by satellite to travel with this speed = [tex]\frac{13}{3}[/tex] seconds

Let the Speed with which the satellite travel = s miles per second

Now, As we know

Speed = [tex]\dfrac{\textrm Distance}{\textrm Time}[/tex]

Or, s = [tex]\frac{\frac{52}{2}}{\frac{13}{3}}[/tex]

or, s = [tex]\frac{59\times 3}{2\times 13}[/tex]

∴ s = 6.80 mps

So, speed = s = 6.80 miles per second

Hence The speed at which the satellite travel is 6.80 miles per second Anwser

$25.30

Step-by-step explanation:

The final bill was $25.30 if you get a haircut that cost $23.if you tip the barber 10% of the total haircut cost.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

You get a haircut that cost $23.if you tip the barber 10% of the total hair cut cost.

Let x be the final bill amount.

The value of x can be found as follows:

x = $23 + 10% of $23

x = 23 + (10/100)23

x = 23 + 0.1(23)

x = 23 + 2.30

x = $25.30

Thus, the final bill was $25.30 if you get a haircut that cost $23.if you tip the barber 10% of the total haircut cost.

Step-by-step explanation:

-23x=10

x=10/-23

x=-10/23

Answer:

x = -15 thus c: is your answer

Step-by-step explanation:

Solve for x:

10 = (-2 x)/3

10 = (-2 x)/3 is equivalent to (-2 x)/3 = 10:

(-2 x)/3 = 10

Multiply both sides of (-2 x)/3 = 10 by -3/2:

(-3 (-2) x)/(2×3) = (-3)/2×10

(-3)/2×(-2)/3 = (-3 (-2))/(2×3):

(-3 (-2))/(2×3) x = (-3)/2×10

(-3)/2×10 = (-3×10)/2:

(-3 (-2) x)/(2×3) = (-3×10)/2

(-3)/3 = (3 (-1))/3 = -1:

(-2-1 x)/2 = (-3×10)/2

(-2)/2 = (2 (-1))/2 = -1:

--1 x = (-3×10)/2

(-1)^2 = 1:

x = (-3×10)/2

10/2 = (2×5)/2 = 5:

x = -35

After 5.11 years, amount due reach $65,000 or more

Solution:

Given that a loan of $46,000 is made.

Rate of interest charged is 7% compounded annually

Need to determine number of years in which the amount due reach $65,000 or more.

In our case

Amount due A = $65000

Loan Amount that is principal P = $46000

Rate of interest r = 7%

Formula for Amount compounded anually is as follows:

[tex]\mathrm{A}=P\left(1+\frac{r}{100}\right)^{n}[/tex]

Substituting the values in above formula we get

[tex]\begin{array}{l}{65000=46000\left(1+\frac{7}{100}\right)^{n}} \\\\ {\frac{65000}{46000}=\left(\frac{107}{100}\right)^{n}} \\\\ {\Rightarrow 1.4130=(1.07)^{n}}\end{array}[/tex]

Applying log on both sides, we

[tex]\begin{array}{l}{\ln 1.4130=n \ln 1.07} \\\\ {=>\frac{\ln 1.4130}{\ln 1.07}=\mathrm{n}} \\\\ {=>\mathrm{n}=\frac{0.34571}{0.067658}=5.1096=5.11}\end{array}[/tex]

Hence after 5.11 years , amount due reach $65,000 or more

The amount invested in the mutual fund that earned 5% was $1,000

The amount invested in the mutual fund that earned 3% was $1,800

Step-by-step explanation:

Let

x ----> the amount invested in the mutual fund that earned 5%

y ----> the amount invested in the mutual fund that earned 3%

we know that

[tex]x+y=2,800[/tex] ----> [tex]y=2,800-x[/tex] ----> equation A

[tex]5\%=5/100=0.05[/tex]

[tex]3\%=3/100=0.03[/tex]

[tex]0.05x+0.03y=104[/tex] ----> equation B

Solve the system by substitution

substitute equation A in equation B

[tex]0.05x+0.03(2,800-x)=104[/tex]

Solve for x

[tex]0.05x+84-0.03x=104[/tex]

[tex]0.05x-0.03x=104-84[/tex]

[tex]0.02x=20[/tex]

[tex]x=\$1,000[/tex]

Find the value of y

[tex]y=2,800-x[/tex]

[tex]y=2,800-1,000=\$1,800[/tex]

therefore

The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800

Answer:

Monthly Salary = $2,600

Step-by-step explanation:

Monthly rent on monthly salary = 25%

Monthly rent = $650.

To determine the monthly sale, we have to use the unitary method.

25% monthly rent on monthly salary means out of $100, Deja spends $25 on her rent.

Therefore,

Deja spends $25 on her rent, when the monthly salary   = $100

Deja spends $1 on her rent, when the monthly salary      = [tex]\frac{100}{25}[/tex]

Deja spends $650 on her rent, when the monthly salary = [tex]\frac{100*650}{25}[/tex]

= [tex]\frac{65000}{25}[/tex]

= $2,600

Her monthly salary is $2,600.
