Answer:

465 in²

Step-by-step explanation:

square area: A = lw

triangle area: A = [tex]\frac{1}{2}[/tex] lw (or base x height)

[tex]A_{square}[/tex] = (15)(15) = 225

[tex]A_{triangle}[/tex] = [tex]\frac{1}{2}[/tex] (8)(15) = 60

There is one square and 4 triangles so...

225 + 4(60) = 465 in²

Answer:

AB ≈ 7.0

Step-by-step explanation:

Using the sine ratio in the right triangle

sin61° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{8}[/tex] ( multiply both sides by 8 )

8 × sin61° = AB , then

AB ≈ 7.0 ( to the nearest tenth )

Answer:

The season will last 4 months after the first month (5 months in total)

Step-by-step explanation:

53 games

9 games first month

11 games per month (since the second one)

x - number of months

9 + 11x = 53

11x = 53-9

11x = 44

x = 4

First Answer:

x = 12

First Step-by-step explanation:

12 + x = -3(4 - x)

12 + x = -12 + 3x

- x - x

—————————

12 = -12 + 2x

+ 12 + 12

—————————

24 = 2x

24/2 = 2x/2

12 = x

Second Answer:

No solution

Second Step-by-step explanation:

2(x - 1/2) = 8 + 2x

2x - 1 = 8 + 2x

+1 +1

—————————

2x = 9 + 2x

- 2x - 2x

—————————

0 = 9

^^ No solution

Step-by-step explanation:

if Juanita has 52 dollars and this sum represents 20%

the bicycle costs 52*5=260 dollars

Answer: -9

Step-by-step explanation:

7 is 8 units away or to the left of -1

count 8 units to the left of -1 which is -9

Answer:

Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.

We can find sum of all 16 test scores = 84(16) = 1344

Outlier found = 78

If outlier is removed new sum = 1344-78 = 1266

Number of entries without outlier = 15

New average = 1266/12 =84.4

We find that average of new data increases.

Also whenever we remove outlier std deviation also would be reduced.

Step-by-step explanation:

Answer:

The mean would decrease.

Step-by-step explanation:

Without the outlier, the mean decreases. The median stays the same with or without the outlier.

others are × by 3

Answer:

12/25 (answer C)

Step-by-step explanation:

as each of the other choices equal to 2/5 after simplification

6/15 (divide 3) = 2/5

18/45 (divide 3) = 6/15 (divide 3) = 2/5

Answer:

Total cost: $30.99

Daniel will have $19.01 left to spend.

Answer:

Daniel can buy 1 shirt

Step-by-step explanation:

We can write an equation out of what they give us in the question.

Each shirt is $20, this can be represented as 20s.

All shipping on orders cost $10.99, this can be represented as 10.99s.

S represents how many shirts Daniel will buy.

The equation is written out like this:

[tex]20s + 10.99s \leq 50[/tex]

Combine like terms:

[tex]30.99s \leq 50\\[/tex]

Now solve

[tex]s \leq 1.6[/tex]

Therefore, if Daniel can only buy one shirt if he has only $50 to spend.

We can't have 2 shirts because that would exceed the $50 limit.

Hope this helps!!

Answer:

[tex]124.16[/tex] cubic meter of clay will be used to create all the pyramids

Step-by-step explanation:

The remaining part of the question is given in the attached file

Solution

The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.

For Rectangular Pyramid,

Volume of three rectangular pyramids

[tex]3 * \frac{BH}{3} = BH[/tex]

Substituting the given values in above equation, we get -

[tex]15.5 * 5 = 77.5[/tex] cubic centimeter

For triangular Pyramid,

Volume of two  triangular pyramids

[tex]2 * \frac{BH}{3}\\2 * \frac{10 * 7}{3}[/tex]

[tex]46.67[/tex]  cubic centimeter

Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid [tex]= 77.7 + 46.67 = 124.16[/tex] Cubic centimeter

Answer:

i hope my answer help you:))

Step-by-step explanation:

{1st question}

b=3b-18=12

=3b=12+18

=3b=30 ( divided by 3)

then b=10

{2nd question}

d = -42-7d=49

=-7d=49+42

=-7d=91 ( divided by -7)

then d= -13

Answer:

Step-by-step explanation:

a+b=36

lets name the 2 numbers a,b

b=a+18

a+a+18=36

2a=36-18

2a=18

a=9

b=27

Answer:

the numbers are 9 and 27

Step-by-step explanation:

equation to the problem: x+y=36

one number (y) is 18 times greater than the other number (x): x+18=y

plug in the 2nd equation to the first equation (systems of equations):

x+(x+18)=36

solve the equation:

2x+18=36

*minus 18 on both sides*

2x=18

*divide the whole equation by 2 to get the value of just one x*

x=9

since variable x is the n smaller number, add 18 to 9 to get the 2nd number:

18+9= 27

y=27

Step-by-step explanation:

We know that opposite sides of a parallelogram are both congruent and parallel. So, we use the equation 3x+5=6x-10

Simplifying this we get x=5

Answer:

X = 5

Step-by-step explanation:

[tex]6x - 10 = 3x + 5 \\ 3x = 15 \\ x = 5[/tex]

Answer:

1) 04.4750

Step-by-step explanation:

The most obvious reason would be that if you put in 3.58 x 1.25 into a calculator the answer u get is 4.4750.

If you want a more technical explanation though, you can say that the combined number of decimal places in the multiplicand and the multiplier is 4, so the product will also have 4 decimal places.

3.58 = two decimal places

1.24 = 2 decimal places

in total, they have 4 decimal places. for the product to have 4 decimal places too you'd count from right to left 4 places, and that's where you'd put the decimal. Hope this helps!

Answer:

1. 45

2. 105

3. 95

4. 85

Step-by-step explanation:

For problems 1 and 4:

Consecutive angles are supplementary in a parallelogram, which means they equal 180.

180 - 135 = 45

180 - 95 = 85

For problems 2 and 3:

Opposite angles are congruent or equal each other in a parallelogram,

Answer:

80%

Step-by-step explanation:

original: 1

Increase 25%: 1.25  if this number becomes 1

1 : 1.25 = x : 1

x = 1 / 1.25 = 0.8   (80%)

check: 0.8 x 1.25 = 1
