.45x25+10.00= 21.25

.65x25+5.00=21.25

Answer: 276

Step-by-step explanation:

multiply 1/3 by 4/4 to make it similar to 5/12 that way you can add them. because the denominator is different from each other you can’t add them. once you do that you get 4/12, you then add 5/12 and that equals 9/12. in order to get to 12/12 you need 3/12 more. this 3/12 represents the 69 guest that chose vegetarian. the 5/12 represents the the guest who chose chicken and the 4/12 represents the ones who chose beef. now that you know 69 people is the same as 3/12 of all the guest. you then realize that 9 is divisible by 3. so you multiply 69 by 3 because 3 goes into 9 3 times. which gives you 207. 207 represents 9/12. and we already know 69 represents 3/12. so you add them together and get 276. sorry if that was confusing but that’s the best way i can explain it.

Answer:

FV= $4,786.01

Step-by-step explanation:

Giving the following information:

Initial deposit (FV)= $4,300

Number of periods (n)= 2 semesters

First, we need to calculate the semi-annual interest rate:

Semi-annual interest rate= 0.11/2= 0.055

Now, to determine the future value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 4,300*(1.055^2)

FV= $4,786.01

Answer:

755.16 cm³

Step-by-step explanation:

We can separate this into two parts -- the bottom rectangular prism and the top triangular prism.

The volume of the bottom part is 12*4*14 = 672 cm³

For the triangular prism, we have an equilateral triangle, with sides 4cm, as well as a length of 12cm. We can find the area of the triangle and multiply it by 12 for our answer. The area of an equilateral triangle is [tex]\frac{\sqrt{3} }{4} 4^{2}[/tex], which is approximately 6.83 -- we can multiply that by 12 to get 83.16 cm³

Add these 2 up to get 755.16 cm³ as our answer

Answer:

It is inversly proportional, there is no constant, the directio is from left to right and from up to down, as x gets larger, y gets less

Step-by-step explanation:

Answer:

y-1 = f(x)

Step-by-step explanation:

Here, we want to choose the equation for the ref graph

The red graph as we can see is above the black

This means it is more positive

The difference between the two is just 1 unit

By the addition of 1 to the y-value of the black graph, we get the red

Thus, we have that;

y- 1 = f(x)

Answer:

Dimes: 10 dimes

Nickles: 6 nickels.

Step-by-step explanation:

Dimes: 10 x 0.10 = 1.00

Nickels: 6 x 0.05 = 0.30

$1.00 + $0.30 = 1.30

Answer:

24.14%

Step-by-step explanation:

Given that,

A team's total salaries is $4,614,244.

The team would like to bring the total down to $3.5 million = $3500000

We need to find the percentage decrease in the team's total salary. The percentage decrease/increase in any value is givenby :

[tex]\%=\dfrac{\text{change in population}}{\text{initial population}}\times 100\\\\=\dfrac{3500000-4,614,244}{4,614,244}\times 100\\\\=24.14\%[/tex]

So, the percentage decrease in the team's total salary is 24.14%.

Answer:

The first angle is the smallest

Step-by-step explanation:

Step one:

given data

Angle 1= x+37

Angle 2= 90

angle 3= x+67

We know that the sum of angle in a triangle is 180

so

x+3+90+x+67= 180

collect like terms

2x+160= 180

2x=180-160

2x= 20

divide both sides by 2

x= 10

Step two:

so

Angle 1= 10+37= 47 °

Angle 2= 90= 90

angle 3= 10+67= 77 °

Answer:

3[tex]\sqrt{3}[/tex] and [tex]\sqrt{7}[/tex]

Step-by-step explanation:

Simplifying surds is similar to collecting like terms in algebra.

If the surds have the same value then collect them by adding/ subtracting their coefficients.

(a)

[tex]\sqrt{3}[/tex] (7 - 2 + 1 - 3)

= [tex]\sqrt{3}[/tex] (3)

= 3[tex]\sqrt{3}[/tex]

(b)

[tex]\sqrt{7}[/tex] (5 + 4 - 8)

= [tex]\sqrt{7}[/tex] (1)

= [tex]\sqrt{7}[/tex]

Answer:

5484 gallons

Step-by-step explanation:

Given that:

Delivery in 1 day = 457 dozen gallons

g = number of gallons delivered on that day

Recall :

1 dozen = 12

Therefore, the number of gallons delivered in 1 day :

457 gallons * 12 = 5484 gallons

Answer:

17

Step-by-step explanation:

follow the order of operations (PEMDAS):   half of 48 is 24

24 / 6 = 4

4 x 4 = 16

16 + 3 = 19

19 - 2 = 17

Answer:

17

Step-by-step explanation:

half of 48 is 24

24 divided by 6 is 4

4× 4= 16

16+3= 19

19-2=17
