Answer:
16
Step-by-step explanation:
total number of cakes baked=55+39=94 cakes
1 box can hold 6 cakes
let the number of box need to hold 94 cakes be x
:- 1 = 6 cakes
x = 94 cakes
cross multiply to get :
6x=94
divide both side by the coefficient of x i.e 6
6x/6=94/6
x= 15.7
because it a real object, the minimum nuber of boxes is 16

1) The population of Leafy Lake starts at 3,000 and grows by 25% every year. What will the population be in 6 years?
how do I solve it
Answer:
Step-by-step explanation:
Rate of increase = r = 25%
n = number of years = 6
P = Current population = 3000
Population after n years = [tex]P*(1 + \frac{r}{100})^{n}[/tex]
[tex]= 3000 * (1 +0.25)^{6}\\\\= 3000 * (1.25)^{6}\\\\= 3000 * 3.8\\\\= 11400=[/tex]

-Chetan K
Answer:
60cm
Step-by-step explanation:
(diagram with colors below)
The two red sides can be visualized as the same length as the length, so the two red segments add up to 18cm. The same thing can be said with the blue segments and the width. We can say the perimeter can be:
18 + 18 + 12 + 12 = 60cm

Answer:
4 option
Step-by-step explanation:
calculate the area of the shape
Answer:
which shape tho and it's easy if there is more than one shape than find the formula for each shape and combine them!
Answer:
the formula for the rectangle is LxW or BxH (however your teacher taught it) which is just 4x15=60. The triangle is bxh÷2 which means 4x15=60 then 60÷2= 30. Add 30+60 which gives you Area=90formula for a circle πxr^2Prove or disprove that the vector V1=(1,2,3) v2=(1,1,1) and V3=(1,1,0) are linearly indepwndent in vector space R^2?
Answer:
The equations are linearly independent in vector space R²
Step-by-step explanation:
The given vectors are;
V₁ = (1, 2, 3), V₂ = (1, 1, 1), V₃ = (1, 1, 0)
For the vectors to be linearly dependent, we have;
a₁·V₁ + a₂·V₂ + a₃·V₃ = 0
Where;
a₁, a₂, and a₃ are not all zero
We get;
[tex]\left[\begin{array}{ccc}1&2&3\\1&1&1\\1&1&0\end{array} \right][/tex]
The vectors are linear dependent, if the following system of equation has a unique set of solution
x + y + z = 0...(1)
2·x + y + z = 0...(2)
3·x + y = 0...(3)
From equation (1), we have;
x = -(y + z)
∴ y + z = -x
Plugging in the value of y + z in equation (2) gives;
2·x + y + z = 0
2·x + y + z = 2·x - x = x = 0
x = 0
From equation (3), we get;
3·x + y = 0, where x = 0, therefore;
3 × 0 + y = 0
∴ y = 0
From equation (1), we have;
x + y + z = 0
Where, x = 0, and y = 0, we get;
0 + 0 + z = 0
z = 0
The vectors, V₁, V₂, and V₃ are linear independent in R³
In two dimensional space, we have
x + y = 0...(1)
2·x + y = 0...(2)
x + y = 0...(3)
Subtracting equation (1) from equation (2) gives;
2·x + y - (x + y) = 2·x - x + y - y = x = 0
∴ x = 0
From equation (1), we get
x + y = 0
∴ 0 + y = 0
∴ y = 0
Therefore, the equations are also linearly independent in vector space R²
Thomas rents a car for his vaccation the milliage included with the 54 miles forer every mile he drives over 54 miles he needs to pay 5 integer 4 by 5 dollar if he drives 69 miles how much extra does he needed to pay
Answer:
$27
Step-by-step explanation:
Thomas rents a car for his vacation. The mileage include with the rental is 54 miles. For every mile he drives over 54 miles, he needs to pay $1 4/5. If he drives 69 miles, how much extra does he need to pay?
Total mileage included with the rental = 54 miles
Additional cost per mile after 54 miles = $1 4/5
Total miles Thomas drives = 69 miles
Extra miles Thomas drives = 69 miles - 54 miles
= 15 miles
how much extra does he need to pay?
Extra cost Thomas needs to pay = Additional cost per mile after 54 miles * Extra miles Thomas drives
= $1 4/5 * 15 miles
= 9/5 * 15
= (9 * 15) / 5
= 135/5
= 27
Extra cost Thomas needs to pay = $27

2 Kenedi has a piece of ribbon that measures
24 inches long. She cuts the ribbon into
15 equal pieces to attach to her dance
costume. Kenedi uses the expression shown to
calculate the length of each piece of ribbon she
uses on her costume.
241 - 15
Which of the following expressions CANNOT be
used to determine the length of each piece of
ribbon?
15
F99=
G (242) (15)
H7+15
J 241-15
Answer:
The length of each ribbon is 1.6 inches
Step-by-step explanation:
From the question, we are told that:
Kenedi has a piece of ribbon that measures 24 inches long. She cuts the ribbon into 15 equal pieces to attach to her dance costume
Hence, the expression that can be used to show how to calculate the length of each piece of ribbon is given as:
24 inches ÷ 15 pieces
= 24 ÷ 15
= 1.6 inches
Therefore, the length of each ribbon is 1.6 inches

Dylan has a bank that sorts coins as they are dropped into it. A panel on the front displays the total number of coins inside as well as the total value of these coins. The panel shows 80 coins with a value of $16.25 inside of the bank.
Answer:
The equations
[tex]x + y = 80[/tex]
[tex]0.25x + 0.1y = 16.25[/tex]
The solution
55 dimes and 25 quarters
Step-by-step explanation:
Given
Let
[tex]x \to[/tex] quarters
[tex]y \to[/tex] dimes
[tex]Total = 80[/tex]
[tex]Worth = \$16.25[/tex]
Required
Set up a system of equation to calculate the number of each coin
The total coin of 80 implies that:
[tex]x + y = Total[/tex]
[tex]x + y = 80[/tex]
A dime = $0.1
A quarter = $0.25
So, the worth of the coin is:
[tex]0.25 * x + 0.1 * y = Worth[/tex]
[tex]0.25x + 0.1y = 16.25[/tex]
So, the equations are:
[tex]x + y = 80[/tex]
[tex]0.25x + 0.1y = 16.25[/tex]
Next, solve for x and y
Multiply the second equation by 4
[tex]0.25x + 0.1y = 16.25[/tex] by 4
[tex]x + 0.4y = 65[/tex]
Subtract from [tex]x + y = 80[/tex]
[tex]x- x + y - 0.4y = 80 - 65[/tex]
[tex]0.6y = 15[/tex]
Solve for y
[tex]y = 25[/tex]
We have:
[tex]x + y = 80[/tex]
[tex]x = 80 - y[/tex]
[tex]x = 80 - 25[/tex]
[tex]x = 55[/tex]
Hence, there are 55 dimes and 25 quarters

An integer is a whole number which cannot be expressed in fractions. For example, 1, 2, 3...
Integer can be positive, negative of zero.
[tex]\frac{10}{2}=5[/tex]
It is a whole number so it is an integer.
- 0.3
It is not an integer as it has a fractional part.

Answer:
3.25 pounds per acre
Step-by-step explanation:
We want to find how much pounds of seed is need per acre. In division, with a numerator and denominator, this works perfectly, with how much we need (of seed) per acre translating into [tex]\frac{26 pounds}{3 acres}[/tex] , with the line representing the per. We can plug this into a calculator to get 3.25 pounds per acre, or [tex]\frac{3.25 pounds}{1 acre}[/tex]

Answer:
c.100
Step-by-step explanation:
first draw a figure of rhombus EFGH to avoid confusions
given
angle E= 3x+5
angle H= 4x
here,
E=G and H=F ( opposite angles of rhombus are equal)
now,
E+G+H+F= 360 ( sum of interior angles in a rhombus)
3x+5+3x+5+4x+4x= 360
x= 25°
we know that,
F= H
F= 4x
F= 4 × 25
F= 100
