Number of times Jenna feeds her cat = 2

Cat food each time

Number of days = 5

Number of cans she bought = 8

Step-by-step explanation:

Required food for each time  

Jenna feeds her cat twice a day

Required food for a day

Required food for 5 days  

Since, 7.5 cans < 8 cans, therefore, Jenna did buy enough cat food for her cat.

x = 60 degrees

Step-by-step explanation:

Answer:

1 Angle A is 44, 2 angle A is 20.

~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Equation for 1 is x + 45 + 82 + x + 65 = 180 x = -1 A = 44 Degrees

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Equation for 2 is x + 21 + 130 + x + 31 = 180  x = -1  Angle A = 20 Degree

Answer:

x=-6

Step-by-step explanation:

x-5x+19=10+2x-3

-4x+19=10+2x-3

-4x+19=7+2x

19=7-2x

12=-2x

x=-6

Answer:

x = 2

Step-by-step explanation:

x - 5x + 19 = 10 + 2x - 3

-4x +19 = 7 + 2x

-2x               -2x

-6x + 19 = 7

      -19     -19

-6/-6x = -12/-6

Answer:

4400 Yards

Step-by-step explanation:

A mile equals 1,760 yards. 2.5 times 1,760 gives you 4,400

It is given that A class walked 2.5 miles for a walk-a-thon then the class walked 4400 yards.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that A class walked 2.5 miles for a walk-a-thon.

WE are asked How many yards did the class walk.

A mile equals 1,760 yards.

If one mile is 1760 yards, then the answer should be

= 1760 times the number of miles.

So  1760*2.5 = 4400

Hence, the class walked 4400 yards.

Answer:

1. [tex]x[/tex] = 9

2. [tex]h[/tex] = 2

3. Infinitely Many Solutions

4. No solution

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

1.) 5(2[tex]x[/tex] + 6) = 8[tex]x[/tex] + 48

Step 1: Expand.

10[tex]x[/tex] + 30 = 8

Step 2: Subtract 30 from both sides.

10[tex]x[/tex] = 8

Step 3: Simplify 8[tex]x[/tex] + 48 − 30 to 8[tex]x[/tex] + 18.

10[tex]x[/tex] = 8

Step 4: Subtract 8[tex]x[/tex] from both sides.

10[tex]x[/tex] − 8

Step 5: Simplify 10[tex]x[/tex] − 8[tex]x[/tex] to 2[tex]x[/tex].

2[tex]x[/tex] = 18

Step 6: Simplify [tex]\frac{18}{2}[/tex] to 9.

[tex]x[/tex] = 9

2.) −3(8 + 3[tex]h[/tex]) = 5[tex]h[/tex] + 4

Step 1: Expand.

−24 − 9[tex]h[/tex] = 5

Step 2: Add 24 to both sides.

−9[tex]h[/tex] = 5

Step 3: Simplify 5[tex]h[/tex] + 4 + 24 to 5[tex]h[/tex] + 28.

−9[tex]h[/tex] = 5

Step 4: Subtract 5[tex]h[/tex] from both sides.

−9[tex]h[/tex] − 5

Step 5: Simplify −9[tex]h[/tex] − 5[tex]h[/tex] to −14[tex]h[/tex].

−14[tex]h[/tex] = 28

Step 6: Divide both sides by −14.

[tex]h[/tex] = [tex]-\frac{28}{14}[/tex]

Step 7: Simplify [tex]\frac{28}{14}[/tex] to 2.

[tex]h[/tex] = 2

3.) 2([tex]y[/tex] − 6) = 3([tex]y[/tex] − 4) − [tex]y[/tex]

Step 1: Expand.

2[tex]y[/tex] − 12 = 3

Step 2: Simplify 3[tex]y[/tex] − 12 − [tex]y[/tex] to 2[tex]y[/tex] − 12.

2[tex]y[/tex] − 12 = 2 − 12

Step 3: Since both sides equal, there are infinitely many solutions.

Infinitely Many Solutions

4.) 8[tex]x[/tex] − 4 = 2(4[tex]x[/tex] − 4)

Step 1: Expand.

8[tex]x[/tex] − 4 = 8

Step 2: Cancel 8[tex]x[/tex] on both sides.

−4 = −8

Step 3: Since −4 = −8 − 4 = −8 is false, there is no solution.

No solution

Answer:

26.2 hours

Step-by-step explanation:

From the given information:

The objective is to determine the value of the 50th percentile.

The median is the 50th percentile, which categorically divides the data into two equal parts. It is a number separating the higher half of a data sample from the lower half. This implies that the median stands in place for the 50th percentile of the data.

Thus, the 50th percentile value is 26.2 hours

Answer:

Options A and C

Step-by-step explanation:

Area of the triangular pane = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                              = [tex]\frac{1}{2}(14)(12)[/tex]

                                              = 84 cm²

Area of the rectangle is given by the formula,

Area = Length × width

Option A.

Area of the rectangular pane = 12 × 7

                                                 = 84 cm²

Option B.

Area of the rectangular pane = 15 × 7

                                                 = 105 cm²

Option C.

Area of the rectangular pane = 21 × 4

                                                 = 84 cm²

Option D.

Area of the rectangular pane = 21 × 8

                                                 = 168 cm²

Option E.

Area of the rectangular pane = 28 × 6

                                                 = 168 cm²

Therefore, rectangular panes A and C have the equal area as the triangular pane has.

B.-7/25

Step-by-step explanation:

edge

The required value of cos(2x) is -7/25. Option B is correct.

sinx = 4/5
cosx < 0

Trigonometry is the study of angles in mathematics.

Here,
cos(2x) = 1-2sin²x
           = 1 - 2 x 4²/5²
           =  1 - 32/25
cos(2x) =  -7/25

Thus, the required value of cos(2x) is -7/25.

Step-by-step explanation

Answer:

x = 3.2

Step-by-step explanation:

Aquí, queremos encontrar el valor de x en la imagen de arriba.

Matemáticamente eso sería;

x / 4 = (x + 16) / (20 + 4)

x / 4 = (x + 16) / 24

Cruz multiplicar 24 * x = 4 (x + 16)

24x = 4x + 64

24x - 4x = 64

20x = 64

x = 64/20 x = 3,2

From the transversal proportionality theorem of parallel lines r,s,t. the value of x is 3.2.

It is given that r, s, t are parallel to each other. The length of the sides is given as 16, 20, 4, x. we need to find the value of x.

If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.

From the transversal proportionality theorem,

When r, s, t are parallel to each other then a / x = b / y

so,

[tex]\rm \frac{16}{x} = \frac{20}{4} \\\rm x = \frac{16}{5} \\\rm x = 3.2[/tex]

Therefore, from the transversal proportionality theorem of parallel lines r,s,t. the value of x is 3.2.
