What is a 15 of the sequence –7,2, 11, ...?

Step-by-step explanation:

[tex]perimeter = 2(l + b) = \\ 2(15 + 8) = 2(23) = 46cm \\ area = lb \\ 15 \times 8 = 120 {cm}^{2} \\ thank \: you[/tex]

Answer:

you just answered your own question

First calculate distances or lengths(Refer to attachment)

[tex]\\ \sf\longmapsto Perimeter=Sum\:of\:sides[/tex]

[tex]\\ \sf\longmapsto 5.3+9+11+9+9.7[/tex]

[tex]\\ \sf\longmapsto 15+29[/tex]

[tex]\\ \sf\longmapsto 44[/tex]

Refer to the attchment

[tex]\\ \sf\longmapsto \left(\dfrac{1+4}{2},\dfrac{1+6}{2}\right)[/tex]

[tex]\\ \sf\longmapsto \left(\dfrac{5}{2},\dfrac{7}{2}\right)[/tex]

EH>OH

[tex]\\ \sf\longmapsto Perimeter[/tex]

[tex]\\ \sf\longmapsto 9.7+5.3+9[/tex]

[tex]\\ \sf\longmapsto 24[/tex]

Answer:

12

Step-by-step explanation:

SOLUTION:  

In a right triangle, the sum of the squares of the

lengths of the legs is equal to the square of the length

of the hypotenuse. The length of the hypotenuse is 13

and the lengths of the legs are 5 and x.  

Answer:

Step-by-step explanation:

1. If A is a subset of B and B is a subset of A then A and B must be equal.

2. The subsets of {a,b,c} are

{ } (emptyset}, {a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c}

3} Since {a,b,c,d,e,f} has 6 elements then there are [tex]2^6[/tex] subsets.

Answer:

-16/5

Step-by-step explanation:

7(x+1)=1-2(5-x)

7x+7=1-10+2x

7x-2x=1-10-7

5x = -16

x = -16/5

Answer: [tex]\huge {x = -\frac{16}{5} }[/tex]

Step-by-step explanation:

Given equation

7 (x + 1) = 1 - 2 (5 - x)

Expand parentheses and apply the distributive property

7x + 7 = 1 - 10 + 2x

Combine like terms

7x + 7 = -9 + 2x

Subtract 2x on both sides

7x + 7 - 2x = -9 + 2x - 2x

5x + 7 = -9

Subtract 7 on both sides

5x + 7 - 7 = -9 - 7

5x = -16

Divide 5 on both sides

5x / 5 = -16 / 5

[tex]\boxed{x=-\frac{16}{5} }[/tex]

Hope this helps!! :)

Answer:

11

Step-by-step explanation:

exceed mean how much and the question is asking how much did he get more so yust 19 -8=11

Answer:

3 eighths are needes to make up the rest of the measure.

Step-by-step explanation:

1/4 + 1/4 + 1/ 8 + x = 1

2/4 + 1/8+x=1

4/8 + 1/8+x=1

5/8 + x=1

x=1 - 5/8

x=3/8

We need three eights.(Because 3/8=1/8+1/8+1/8 and 1/8 represents an eights)

Answer:

4.5 / 9 = 1/2

Answer:

3*(d + r^2)

Step-by-step explanation:

Sometimes you read what is needed from front to back and other times it goes from back to front. This is one of those things that goes from back to front.

d and r^2 = d + r^2  In this case and means plus.

Now you deal with the three.

3(d + r^2) which creates the distributive property.

Answer:

3*(d + r^2) is correct answer

28/5

Answer:

A. 26

Step-by-step explanation:

The base number (the first number) is what will be multiplied and the exponent is how many times you're multiplying the number, so for this it would be

2 x 2 x 2 x 2 x 2 x 2

Answer:

False False False because freezing point is 100 degree celsius

12: Equal, because the cardinal number of {x,y,z} are same as {a,b,c}, that is, 3.

13: Not equal, because in set {0}, there is one element , while in set { } , there are no elements at all .

Hope it helps you. Have a nice day!

Answer:

k < 4

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

Then the discriminant Δ = b² - 4ac informs us about the nature of the solutions.

• If b² - 4ac > 0 then 2 real and distinct solutions

• If b² - 4ac = 0 then 1 real and repeated solution

• If b² - 4ac < 0 then no real solutions

4x² + 8x + k = 0 ← is in standard form

with a = 4, b = 8 , c = k , then

b² - 4ac = 8² - (4 × 4 × k) = 64 - 16k

For two real solutions

64 - 16k > 0 ( subtract 64 from both sides )

- 16k > - 64

Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity.

k < 4

Then any value less than 4 will ensure the equation has two real solutions

Answer:

The ratio of purple flowers to total flowers is 16 to 21 is NOT TRUE because your total is already 21 so it would make no sense for 16 to be in the ratio

Answer:

[tex](x - 2) \times (x + 2) \times ( {x}^{2} + 4)[/tex]

Step-by-step explanation:

[tex] {x}^{4} - 16[/tex]

➡️ [tex] {x}^{2 \times 2} - 16[/tex]

➡️ [tex] {x}^{2 \times 2} - {4}^{2} [/tex]

➡️ [tex]( {x}^{2} {)}^{2} - {4}^{2} [/tex]

➡️ [tex]( {x}^{2} - 4) \times ( {x}^{2} + 4)[/tex]

➡️ [tex](x - 2) \times (x + 2) \times ( {x}^{2} + 4)[/tex]

Answer:

your fractions will go in order of 1/4, 2/5, 5/8, 4/6

Step-by-step explanation:

a. 2/5 < 1/2 and 4/6 > 1/2 so 2/5 < 4/6

b. 5/8 > 1/2 and 1/4 < 1/2 so 5/8 > 1/4

c. 4/6 > 1/2 and 4/6 < 2/2 and 5/8 > 1/2 and 5/8 < 2/2 and 5/8  ?? cannot see this

Answer:

  total: 2.85 hours = 2 17/20 hours

Step-by-step explanation:

Strategy: convert all fractions to decimals, determine weeding and mowing times, and add the three times to find the total.

  3/4 = 0.75

  1/5 = 0.2

Solution:

raking time: 0.75 hours

weeding time: 0.75 +0.2 = 0.95 hours

mowing time: 0.95 +0.2 = 1.15 hours

__

Total time: 0.75 +0.95 +1.15 = 2.85 hours = 2 17/20 hours

_____

Additional comment

You may recognize that 0.95 is the middle of three equally-spaced values. Then the total will be 3×0.95 = 2.85 hours.

Answer:

1. -4/7

2. 4/3

3. x^2 + 16x + 63

4. x^2 + 19x + 90

Step-by-step explanation:

1. (1, 8) and (8, 4)

slope = m = (8 - 4)/(1 - 8) = -4/7

2. (2, 4) and (5, 8)

slope = m = (8 - 4)/(5 - 2) = 4/3

3. (x + 9)(x + 7) =

= x^2 + 7x + 9x + 63

= x^2 + 16x + 63

4. (x + 10)(x + 9) =

= x^2 + 9x + 10x + 90

= x^2 + 19x + 90

Answer:

8.3100 x [tex]10^{4}[/tex]

Explanation:

83100 in this form would be 8.3100 x [tex]10^{4}[/tex] because you can see 4 digits after the decimal point which would be raised to the 4th power of 10.
