someone help me with my math homework?

Answer:

15%

Step-by-step explanation:

First, let's find how many pounds the dog's weight increased by during the year.

80 - 64 = 16

Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).

[tex]\frac{16}{64}[/tex] • 100 = 0.25 • 100 = 25%

Answer: 3

Answer:

1

Step-by-step explanation:

4 * 1/

4

= 4 · 1/

1 · 4

= 4/

4

= 1 · 4/

1 · 4

= 1

Answer:

$50

Step-by-step explanation:

Price of the cell phone bought p = $40

% of markup in price = 25%

Selling price of the cell phone = p + (%)p

Selling price of the cell phone = P + (0.25)p

Selling price of the cell phone = p + 0.25p

Selling price of the cell phone = 1.25p

Selling price of the cell phone = 1.25 * $40

Selling price of the cell phone = $50

4.3x+5x=16+7-(7)

9.3x=16

x= 1.72

give me a brainliest if possible. please.. tnx

Answer:  1.72.......

Step-by-step explanation:  4.3x + 7 + 5x = 16 + 7

=> 7 + (5x + 4.3x) = 16 + 7

7 + 9.3x = 23

9.3x = 23 - 7    [ 7 becomes -7 when transferred to RHS]

9.3x = 16

x = 16 /9.3    [ 9.3 becomes 1/9.3 when transferred to RHS]

x = 1.72......

Hope it helped u,

Step by step explanation

Question number 3 : Twenty percent of Mrs.Reynold's monthly earnings is budgeted for food. If $ 156.00 goes for food , what are her total monthly earnings ?

☄ [tex] \underline{ \underline{ \sf{Solution}}}: [/tex]

Now , According to question , Set up an equation and solve for x :

[tex] \tt{20\% \: of \: x \: = \: 156.00}[/tex]

⤑ [tex] \tt{ \frac{20}{100} x = 156}[/tex]

⤑ [tex] \sf{ \frac{1}{5} x = 156}[/tex]

⤑ [tex] \tt{x = 156 \times 5}[/tex]

⤑ [tex] \boxed{ \sf{x = \$ \: 780}}[/tex]

Step 1: Cross-multiply.

15 /x = 5 /6

(15)*(6)=5*x

90=5x

Step 2: Flip the equation.

5x=90

Step 3: Divide both sides by 5.

5x /5 = 90 /5

x=18

Answer:

x=18

Answer:

x=18

Step-by-step explanation:

divide 15 by 5/6= 15 times 6/5, simplify, 3 times 6, simplify, 18

Answer:

[tex] \frac{BD}{AD} = \frac{5}{7} [/tex]

Step-by-step explanation:

Coordinate of B = 1

Coordinate of D = 6

Coordinate of A = -1

BD = |1 - 6| = 5 units

AD = |-1 - 6| = |-7| = 7 units

[tex] \frac{BD}{AD} [/tex]

Plug in the values

[tex] \frac{BD}{AD} = \frac{5}{7} [/tex]

Answer:

Answer:

n < -10

Step-by-step explanation:

n+7 < -3

subtract 7 from both sides

n+7-7 < -3-7

n < -10

The question is incomplete, the complete question is;

Based on the information in the table, is the cost of the apples proportional to the weight of apples?

Pound of apples:

2

3

4

5

Cost of apples:

$3.76

$5.64

$7.52

$9.40

2. Based on the information in the table, is the cost of the pizza proportional to the number of toppings?

Number of toppings:

2

3

4

5

Cost of pizza:

$11.99

$13.49

$14.99

$16.49

Answer:

See explanation

Step-by-step explanation:

Based on the information provided, there is a proportional relationship between the cost of the apples and the weight of the apples as well as between the number of toppings and the cost of the pizza.

We know that there is a proportional relationship when there is a linear increase  or decrease in the two quantities in the relationship. This increase or decrease is usually by a constant value.

In the relationship between the weight of apples and the cost of apples, the cost of apples increases steadily by $1.88 which shows a proportional relationship.

Also, in the relationship between the number of toppings and the cost of pizza, the cost of pizza increases by $1.5 which shows a proportional relationship between the two.

Answer:

[tex]x = - 3[/tex]

Step-by-step explanation:

[tex] - 2(3x - 2) + 2x = - 6x - 10[/tex]

[tex] = > - 6x - 4 + 2x = - 6x - 10[/tex]

[tex] = > - 4x - 4 = - 6x - 10[/tex]

[tex] = > - (4x + 4) = - (6x + 10)[/tex]

[tex] = > 4x + 4 = 6x + 10[/tex]

Keeping all like terms in L.H.S ,

[tex] = > 6x - 4x = 4 - 10[/tex]

[tex] = > 2x = - 6[/tex]

[tex] = > x = \frac{ - 6}{2} = - 3[/tex]

Answer:

V = 125.6 in³

Step-by-step explanation:

let V be volume, h the height and r the radius, then the equation relating the quantities is

V = khr² ← k is the constant of variation

To find k use the condition V = 402.12, h = 8, r = 4

402.12 = k × 8 × 4² = 128k ( divide both sides by 128 )

3.14 = k [ note 3.14 is π )

V = 3.14hr² ← equation of variation [ V = πr²h ]

Given r = 2 and h = 10, then

V = 3.14 × 10 × 2² = 3.14 × 40 = 125.6

Answer:

1/10 acres

Step-by-step explanation:

A land developer wants to divide up 9/10 of an acre Of land into equally sized lots for houses. He wants to build nine houses. How big can he make each lot?

This is calculated as:

1 lot = 1 house

Hence:

9 house = 9/10 acres

1 house = x

Cross Multiply

9x = 9/10 acres

x = 9/10 ÷ 9

x = 9/10 × 1/9

x = 1/10 acres

Hence, the size of each lot when divided equally = 1/10 acres

Step-by-step explanation:

m∠LON ≅ m∠M        Property of Parallelogram; Opposite angles are congruent

m∠M = 118°                Given

m∠LON = 118°            Substitution

m∠OLN + m∠LNO + m∠LON  = 180°      Sum of angles in a triangle

m∠OLN + 118° + 22° = 180°                      Substitution

m∠OLN = 40°                                            Algebra
