Answer:

(Choice A) A 16:10

(Choice C) C 48:30

(Choice D) D 32:20

Step-by-step explanation:

Given ratio

8 : 5

Select three ratios that are equivalent to 8:5

Check all options

(Choice A) A 16:10

= 16 / 10

Dividing by 2

= 8 / 5

= 8 : 5

(Choice B) B 50:80

= 50 / 80

Dividing by 10

= 5 / 8

= 5 : 8

(Choice C) C 48:30

= 48 / 30

Dividing by 6

= 8 / 5

= 8 : 5

(Choice D) D 32:20

= 32 / 20

Dividing by 4

= 8 / 5

= 8 : 5

(Choice E) E 64:35

= 64 / 35

The equivalent ratios to 8 : 5 are

(Choice A) A 16:10

(Choice C) C 48:30

(Choice D) D 32:20

Since the 2 legs are congruent, then

3x + 12 = 33 ( subtract 12 from both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Answer:

The amount of cookies in the small tray = x = 19 cookies

The amount of cookies in the Large tray = y = 40 cookies

Step-by-step explanation:

Let

The amount of cookies in the small tray = x

The amount of cookies in the Large tray = y

We are told:

A caterer is making cookie trays for upcoming holiday parties.

This morning, she made 4 small trays and 4 large trays, which contain a total of 236 cookies.

This is represented Mathematically as:

4x + 4y = 236..... Equation 1

In the afternoon, she made 4 small trays and 1 large tray, which contain a total of 116 cookies.

This is represented Mathematically as:

4x + y = 116 ........ Equation 2

y = 116 - 4x

We solve the above equations using the substitution method

We substitute 116 - 4x for y in Equation 1

4x + 4y = 236..... Equation 1

4x + 4(116 - 4x) = 236

4x + 464 - 16x = 236

Collect like terms

4x - 16x = 236 - 464

-12x = -228

x = -228/-12

x = 19 cookies

Solving for y

y = 116 - 4x

y = 116 - 4 × 19

y = 116 - 76

x = 40 cookies

The number of cookies the different sized trays contained is given as:

The amount of cookies in the small tray = x = 19 cookies

The amount of cookies in the Large tray = y = 40 cookies

Answer:

[tex]x^3 + 3x\²y + 3xy^2 + y[/tex] [tex]=283[/tex]

[tex]When\ x = 3\ and\ y = 4[/tex]

Step-by-step explanation:

Given

[tex]x^3 + 3x\²y + 3xy^2 + y[/tex]

Required

Solve when x = 3 and y = 4

To do this, we simply substitute  3 for x and 4 for y in [tex]x^3 + 3x\²y + 3xy^2 + y[/tex]

[tex]3^3 + 3 * 3^2 * 4 + 3 * 3 * 4^2 + 4[/tex]

[tex]27 + 3 * 9 * 4 + 3 * 3 * 16 + 4[/tex]

[tex]27 + 108 + 144+ 4[/tex]

[tex]283[/tex]

Hence:

[tex]x^3 + 3x\²y + 3xy^2 + y[/tex] [tex]=283[/tex]

Answer:

f(g(5)) = 4

Step-by-step explanation:

It says to find the value of f(g(5)). In this case, we first have to find g(5).

Plug 5 into g(x) = -x+5

g(5) = 0

Now, f(g(5)) is f(0), since g(5) was found out to be 0.

Plug in 0 into 2x² + 7x + 4

2(0)² + 7(0) + 4 = 0 + 0 + 4 = 4

So the answer is 4.

Answer:

16n + 41

Step-by-step explanation:

2(-n - 3) - 7(5 + 2n) (Given)

-2n - 6 - 35 - 14n (Distribute)

-16n - 41 (Add like terms)

16n + 41 (Divide by a factor of -1)

Answer:

B. -16n - 41

Step-by-step explanation:

Use the distributive property:

2(-n - 3) - 7(5 + 2n)

-2n - 6 - 35 - 14n

Combine like terms:

(-2n - 14n) + (-6 - 35)

-16n - 41

Answer:

B = Blue paint = 3.5 gallons

Y= Yellow paint = 24.5 gallons

Step-by-step explanation:

Let B = Blue paint

Y= Yellow paint

Your mixing blue paint and yellow paint to get a total of 28 gallons.

B + Y = 28 gallons

You want to use 7 times yellow paint as blue.

This means, 7B = Y

How many gallons of each should you use ?

Hence,

B + Y = 28

B + 7B = 28

8B = 28

B = 28/8

B = 3.5 gallons

B + Y = 28 gallons

Y + 3.5 gallons = 28 gallons

Y = 28 gallons - 3.5 gallons

Y = 24.5 gallons

B = Blue paint = 3.5 gallons

Y= Yellow paint = 24.5 gallons

Answer:

  EL/EF and OS/OJ

Step-by-step explanation:

In the similar triangles, angle F and angle J have the same measure, so will have the same tangent. The tangent is the ratio of the opposite side to the adjacent one.

In ΔFEL, the desired ratio is ...

  tan(F) = EL/EF . . . . . 2nd choice

In ΔJOS, the equivalent ratio is ...

  tan(J) = tan(F) = OS/OJ . . . . . 7th choice

Answer:

First choice, 47/100

Step-by-step explanation:

16 + 9 + 22 + 26 + 15 + 12 = 100

The even numbers are 2, 4, and 6. They rolled two 9 times, four 26 times, and six 12 times. Added together and they're 47, so 47/100

There's no simplification of this fraction as theres no number that can be used to divide both 47 and 100

Answer:

This implies that

x2+2ax=4x−4a−13

or

x2+2ax−4x+4a+13=0

or

x2+(2a−4)x+(4a+13)=0

Since the equation has just one solution instead of the usual two distinct solutions, then the two solutions must be same i.e. discriminant = 0.

Hence we get that

(2a−4)2=4⋅1⋅(4a+13)

or

4a2−16a+16=16a+52

or

4a2−32a−36=0

or

a2−8a−9=0

or

(a−9)(a+1)=0

So the values of a are −1 and 9.

Answer:

[tex]\frac{492}{65}[/tex]

Step-by-step explanation:

Using the trigonometric identity

sin²A + cos²A = 1 , then

sinA = [tex]\sqrt{1-cos^2A}[/tex] thus

sinA = [tex]\sqrt{1-(5/13)^2}[/tex]

        = [tex]\sqrt{1-\frac{25}{169} }[/tex]

        = [tex]\sqrt{\frac{144}{169} }[/tex] = [tex]\frac{12}{13}[/tex] , then

tanA = [tex]\frac{sinA}{cosA}[/tex] = [tex]\frac{\frac{12}{13} }{\frac{5}{13} }[/tex] = [tex]\frac{12}{5}[/tex]

Thus

2tanA + 3sinA

= 2 × [tex]\frac{12}{5}[/tex] + ( 3 × [tex]\frac{12}{13}[/tex] )

= [tex]\frac{24}{5}[/tex] + [tex]\frac{36}{13}[/tex]

= [tex]\frac{312}{65}[/tex] + [tex]\frac{180}{65}[/tex]

= [tex]\frac{492}{65}[/tex]

Step-by-step explanation:

Side length of heptagon = 20.3cm / 7 = 2.9cm.

The heptagon is made out of 7 congruent triangles, each with height 3.0cm and base 2.9cm

Hence area of heptagon

= 7 * [(0.5)(3.0cm)(2.9cm)]

= 7 * 4.35cm²

= 30.45cm².

Answer:

The account will take 7 years to reach a value of $4,020

Step-by-step explanation:

Compound Interest

When it occurs interest in the next period is then earned on the principal sum plus previously accumulated interest.

The formula is:

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

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Ella invested P=$2,700 in an account with an interest rate of r=5.4% (0.054) compounded monthly. Since there are 12 months in a year, n=12.

It will be calculated when will the account have a value of A=$4,020. Substituting all the values in the formula:

[tex]{\displaystyle 4,020=2,700\left(1+{\frac {0.054}{12}}\right)^{12t}}[/tex]

Calculating:

[tex]{\displaystyle 4,020=2,700\left(1.0045)^{12t}}[/tex]

Dividing by 2,700:

[tex]{\displaystyle \frac{4,020}{2,700}=\left(1.0045)^{12t}}[/tex]

To solve this equation for t, we need to apply logarithms:

[tex]{\displaystyle \log\frac{4,020}{2,700}=\log\left(1.0045)^{12t}}[/tex]

Applying the logarithm power rule:

[tex]\displaystyle \log\frac{4,020}{2,700}=12t\log 1.0045[/tex]

Dividing by 12log 1.0045:

[tex]\displaystyle t=\frac{\log\frac{4,020}{2,700}}{12\log 1.0045}[/tex]

Calculating:

t= 7.39 years

Rounding to the nearest year, the account will take 7 years to reach a value of $4,020
