Answer:

65

Step-by-step explanation:

2x+15 = 145

2x = 145-15

2x = 130

x = 65

Answer:

I think x=65

Step-by-step explanation:

Since both of the angles are vertical to one another that would mean they are equal to each other. When writing 2x +15=145 you would solve for x.

Step by step Explanation:

The question is incomplete as the plots that show the distance traveled is not given.

So, I will answer the question with the attached plots.

The number of dots on each day represents the number of miles travelled on that day.

From Elizabeth's plot, the shortest is 1 mile on day 4 (i.e. 1 dot on day 4)

From Izak's plot, the shortest is 2 miles on day 3 (i.e. 2 dots on day 3)

Calculate the difference between both distances

[tex]d = 2\ miles - 1\ mile[/tex]

[tex]d = 1\ mile[/tex]

Hence, the shortest distance travelled by Izak is 1 mile more than the shortest by Elizabeth

$792 in interest

Step-by-step explanation:

16500(0.048) = 792

Answer:

792 is the answer

Step-by-step explanation:

Well, what I did was I figured out 4.8% as a decimal =  (0.048) and then I timed that with $16,500. Like this --> (0.048×16,500). Which gave me the total of (792)!

Answer:

[tex]22.5\:\text{minutes}[/tex]

Step-by-step explanation:

In 15 minutes, Jennifer has mowed [tex]\frac{2}{3}[/tex] of the lawn (given in problem). This means that it will take her [tex]\frac{3}{2}\cdot 15=22.5\:\text{minutes}[/tex] to mow the entire lawn, assuming a constant rate.

Equation:

Let [tex]x[/tex] represent the entire lawn:

[tex]\frac{2}{3}x=15,\\x=\frac{15}{\frac{2}{3}}=15\cdot \frac{3}{2}=\boxed{22.5}[/tex]

The function that produces the sequence with n: [1,2,...,] is "f(n) = 9n + 17" (Option C). See the explanation below.

Note that we want a function which produces the sequence 26, 35, 44, 53, 62, if {1, 2, 3......n} is plugged into it.

Lets test the function with the integer 1:

9 (1) + 17

= 9+ 17

= 26 [Correct]

Lets true 2;

9(2) + 17

= 18 + 17

= 35 [Correct]

Lets try 3;

9 (3) + 17

= 27 + 17

= 44 [Correct]

Hence the selected function (Option C) is correct.

Answer: 130 kg 920 g

Step-by-step explanation:

Given

The weight of the goat is 59 kg  720 g

The combined weight of goat and cow is 190 kg 640 g

Suppose, the weight of the cow is x kg

We know, 1 kg=1000 g

Converting weight into kg

Goat weight

[tex]=59+0.720\\=59.720\ kg[/tex]

Total weight

[tex]=190+0.640\\=190.640\ kg[/tex]

Then, the cow weight is given by

[tex]\Rightarrow 190.640-59.720\\\Rightarrow 130.920\ kg\ \text{or}\ 130\ kg\ 920\ g[/tex]

Answer:

2(√17b³ )c⁵

Step-by-step explanation:

We are to simplify the expression given below

√68b³c¹⁰

Simplifying 68

= √(17 × 4)b³c¹⁰

Hence

= 2√17b³c¹⁰

= 2 √17b³ × √c¹⁰

= 2 √17b³ × c¹⁰/²

= 2(√17b³ )c⁵

Answer:

there are 7 boxes in the stack.

Step-by-step explanation:

After a quick online search, I've found that the dimensions of each box are:

Height = H = 18cm

Length = L = 40cm

Width = W = 21cm

If we stack the boxes, then the only thing that changes in the figure is the height, so if we stack N boxes, the dimensions will be:

Height = H = N*18cm

Length = L = 40cm

Width = W = 21cm

And for a rectangular prism of height H, width W, and length L, the surface is:

S = 2*(H*W + W*L + H*L)

Then for our stack of boxes, the surface is:

S = 2*(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm)

And we know that the total surface is 17,052 cm^2

Then we just need to solve:

2*(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = 17,052 cm^2

(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = (17,052 cm^2)/2

(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = 8,526 cm^2

840 cm^2 + N*720 cm^2 + N*378 cm^2 = 8,526 cm^2

N*(720 cm^2 + 378 cm^2) =  8,526 cm^2 - 840 cm^2 = 7,686 cm^2

N*(1,098 cm^2) = 7,686 cm^2

N = (7,686 cm^2)/(1,098 cm^2) = 7

So there are 7 boxes in the stack.

Answer:

  -4.2

Step-by-step explanation:

The linear term is missing from the quadratic, which means it is symmetrical about the vertical line x=0. For each x-intercept greater than 0, another is its opposite. The opposite of 4.2 is -4.2

The other x-intercept is -4.2.

__

Consider the parent function ...

  y = x^2

which is symmetrical about the y-axis.

Transforming it to ax^2 +k causes it to be scaled vertically by a factor of 'a', and shifted vertically up k units. Neither of these transformations affects the horizontal position of the curve, so it remains symmetrical about the y-axis. Attached is one example of a quadratic of this form with an x-intercept of 4.2.
