Answer:

The answer should be C. 0.29563

Step-by-step explanation:

(please give brainliest)

Bathroom = 14 ft x 7 ft = 98 ft^2

Living Room = 21 ft x 14 ft = 294 ft^2

Closet = 7 ft x 7ft = 49 ft^2

21 x (7 + 3.5)

21 x 10.5

210 + 10.5 = 220.5

Bedroom =  21 ft x 10.5 ft = 220.5 ft^2

14 x (7 + 3.5)

14 x 10.5

140 + 7

Kitchen = 14 ft x 10.5 ft = 147 ft^2

Answer:

9 hamburgers

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] × 2 = [tex]\frac{1}{2}[/tex]

[tex]\frac{1}{2}[/tex] × 5 =[tex]2\frac{1}{2}[/tex]

[tex]\frac{1}{4}[/tex] × 9 =2 [tex]\frac{2}{4}[/tex]     2

,so 9 hamburgers can be made

We need to find the number of quarter pound hamburgers that can be made from given the amount of ground beef.

10 quarter pound hamburgers can be made.

The amount of ground beef available is [tex]2\dfrac{1}{2}[/tex] pounds.

One hamburger has a mass of [tex]\dfrac{1}{4}[/tex] pound.

[tex]1\ \text{hamburger}=\dfrac{1}{4}\ \text{pound of beef}[/tex]

[tex]\\\Rightarrow 1\ \text{pound of beef}=4\ \text{hamburgers}[/tex]

[tex]2\dfrac{1}{2}\ \text{pound of beef}=(2+\dfrac{1}{2})\times4=10\ \text{hamburgers}[/tex]

So, a total of 10 quarter pound hamburgers can be made.

Answer:

55

Step-by-step explanation:

Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal

<A = <C

3x+40 =x+50

Subtract x from each side

3x-x+40 = x+50-x

2x +40 = 50

Subtract 40 from each side

2x+40-40=50-40

2x = 10

Divide each side by 2

2x/2=10/2

x = 5

We want to find <A

Answer: 292

Step-by-step explanation:

The formula is: [tex]a_n=a_1+(n-1)d[/tex]

Where;

[tex]a_n=[/tex] [tex]n^t^h[/tex] term or the term we're trying to find.

[tex]a_1=[/tex] First term

[tex]d=[/tex] Common difference.

To find the common difference, take [tex]a_2-a_1[/tex], or [tex]a_3-a_2[/tex] or [tex]a_4-a_3[/tex]

4-(-2)=?

4+2=?

6 -> this is our common difference

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

10-4=?

6 -> this is our common difference

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

16-10=?

6 -> this is our common difference

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

Knowing this, we plug into the formula the number we're trying to find.

[tex]a_n=a_1+(n-1)d\\a_5_0=-2+(50-1)6\\a_5_0=-2+(49)6\\a_5_0=-2+294\\a_5_0=292[/tex]

Answer:

750 × 1/10  = 750/10 = 75

Step-by-step explanation:

The best way to really predict the outcome of multiplying 750 by 0.1 without calculator is firstly, converting the decimal to a fraction to easily do the multiplication in your head.

Since one of the multiplicand is a decimal the products will be much complicated therefore, to convert the decimal number 0.1 to a fraction number we shift the point to the right hand side which simply translate to 1/10.  The trick here is the number of times we shift the point will determine the number of zeros the denominator will possess.  Assuming we have 0.12 as the decimal, it is required we shift the point twice and the resulting value we become 12/100. If the decimal is 0.123 it is required we shift the point 3 times , the resulting value will be 123/1000. Not the number of times we shift the point will determine the number of zero's of the denominator.

Finally, the 2 multiplicands are now 750 and  1/10 which is more easier to manipulate in our head.  

750 × 1/10  = 750/10 = 75( you just cancel the zeros)

Answer:

Option A,$320.98  is correct

Step-by-step explanation:

The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.

last balance as shown by the statement was $152.58

new charges were $213.40

payment made by Elijah was  $45

new balance=$152.58+$213.40-$45=$320.98

The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.

Answer:

Other answer is incorrect. Elijah's new balance would be $322.59

Answer:

24 meters

Step-by-step explanation:

Alright. Your question had errors, but I managed to scramble together some answers.

The right triangle has a total of 3 sides, 2 which are 8 and 6. We need to find the hypotenuse.

Let's use the Pythagorean Theorum.

a^2 + b^2 = c^2

8^2 + 6^2 = c^2

64 + 36 = 100

To get c by itself, square root it.

[tex]\sqrt{100} =10[/tex]

You found the hypotenuse :D

Add it up!

8 + 6 + 10 = 24 meters

Answer:

Remember this formula.

Step-by-step explanation:

[tex]\sqrt{a^{2}+b^{2}=c^{2}[/tex]

If your legs are 8 and 6, the last side is the hypotenuse, which is always the largest side of a right triangle. You calculate it's length by taking the measurements of leg A and leg B, and squaring both of them, or raising them both by the power of 2.

This will equal C, or your hypotenuse, but it will be squared, so you have to find its square root to get the actual measurement, which is why the equation has a square root sign over it, so the answer is automatically squared when put into a calculator.

8 x 8 = 64 [or [tex]8^{2}[/tex]]

6 x 6 = 36 [or [tex]6^{2}[/tex]]

[tex]8^{2}+6^{2}=100\\\sqrt{100}=10[/tex]

[tex]\sqrt{8^{2}+6^{2}=10[/tex]

Answer:

Step-by-step explanation:

5)

DG= 60 (whole)

DO= 4x-3 (Part)

OG= 2x+ 21 (Part)

4x-3+ 2x+21= 60

6x+18=60

6x=42

x=7

Using this we can solve for DO and DG

DO= 4*7-3

DO= 25

DG= 2*7+21

DG= 14+ 21= 35

6)

TB is whole

TU is part

UB is part

5x= 4x-1+2x-1

5x=6x-2

x=2

UB= 2*2-1= 4-1= 3

TU= 4*2-1= 8-1= 7

Answer: 11,682.4 miles

Step-by-step explanation:

We can think the planet as a circle:

if we have a circle of radius R, and an arc of A degrees in the circle, the lenght of the arc is:

L = (A/180°)*3.14*R

Here we know that:

L = 4076 miles

A = 20°

Then:

4076mi = (20/180)*3.14*R = 0.3489*R

R = 4076mi/0.3489 = 11,682.4 miles

Answer:

10x + 8 = 21

x = 1.3

Step-by-step explanation:

a)

In pentagon ABCDE,

AB = DE = 2x + 3 and BC = CD = x + 1

Perimeter of pentagon ABCDE = 21

4x + 2(2x + 3) + 2(x + 1) = 21

4x + 4x + 6 + 2x + 2 = 21

[tex] \purple {\boxed {\bold{10x + 8 = 21}}} [/tex]

b)

10x = 21 - 8

answer:

option A y≤3x

The system of equations that matches the graph is as follows:

y ≤ 3x

y > -2x - 1

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The line y = 3x represents the boundary for the first inequality, and the line y = -2x - 1 represents the boundary for the second inequality.

The first inequality has a less than or equal to sign, the region below the line y = 3x is shaded.

The second inequality has a greater than sign, the region above the line y = -2x - 1 is shaded.

The overlapping region of the two shaded regions represents the solution to the system of inequalities, which is the region where both inequalities are true. Therefore, the solution is the triangle-shaped region that is below the line y = 3x and above the line y = -2x - 1.

The shaded region represents the solution to the system of inequalities y ≤ 3x and y > -2x - 1.

Answer:

Between 10 and 11.

Step-by-step explanation:

To begin, we can look at the problem as such. If we take the first answer choice, we can find the squares of both numbers giving us: (Remember that the area of a square is A=L²)

10²= 100

11²= 121

Since the given area is in between these two numbers, this means that the side length must be between 10 and 11.
