5x + 15 = 75 - 25x

Answers

Answer 1

Answer:

X = 3

Step-by-step explanation:

Answer 2

Answer:

= 2

Step-by-step explanation:5x+15=75-25x

We move all terms to the left:

5x+15-(75-25x)=0

We add all the numbers together, and all the variables

5x-(-25x+75)+15=0

We get rid of parentheses

5x+25x-75+15=0

We add all the numbers together, and all the variables

30x-60=0

We move all terms containing x to the left, all other terms to the right

30x=60

x=60/30

x=2

How do you know when to use the less than symbol and when to use the less than or equal to symbol when writing an inequality for a situation? ​

Answers

This depends on the situation. For context, you use less than when your inequality CANNOT exceed more than.

You would use less than or equal to if your inequality can be equal to a number. Here's an example.

Determine the amount of time it will take for Daniel and
for Brandon to get to the taco truck.
Use paper and/or a calculator as necessary,

Answers

Answer:

Daniel = 207 | Brandon = 196.2

Step-by-step explanation:

Brandon will reach the taco truck first.

• Daniel's time can be found by using the expression 327.6/3 + 489/5, which is 207 seconds.

• Brandon's time can be found by using the expression

327.6^+489^2/3 [Sqaured]

The time taken by Brandon will be 196.2 seconds while Daniel will be 207 seconds.

What is a triangle?

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°.

⊕ Time is taken by Brandon ;

   

      01) Time taken in sand

             Time = 327.6/3 = 109.2 seconds.

     02) Time is taken on the boardwalk

             Time = 489/5 = 97.8 seconds.

Total time taken by Brandon = 109.2 + 97.8 = 207 seconds.

Time is taken by Daniel;

         By Pythagoras theorem

         Distance by Daniel = √(327.6² + 489² ) = 588.60 feets.

        Time = 588.60/3  = 196.2 seconds.

So the time taken by Brandon will be 207 seconds and Daniel will be 196.2 seconds.

A square has side length 3 units. What is the length of the diagonal?

Answers

Answer:

  C. 3√2 units

Step-by-step explanation:

The diagonal of a square is √2 times the side length. For a square with side length 3, the diagonal is 3√2.

__

If you like, you can see this using the Pythagorean theorem.

  d² = s² + s² . . . . . where d is the diagonal, and s is the side

  d² = 2s²

  d = √(2s²) = s√2

For s=3, ...

Solve the following quadratic equation for all values of x in simplest form. 4(3x - 5)^2+5 = 13 (will give brainly)

Answers

Answer:

Step-by-step explanation:

4(3x-5)^2+5=13

4(3x-5)^2+5-13=0

As  (a-b)^2=a^2-2ab+b^2

4((3x)^2-2(3x)(5)+(5)^2)-8=0

4(9x^2-30x+25)-8=0

36x^2-120x+100-8=0

36x^2-120x+92=0

using the Quadratic Formula where

a = 36, b = -120, and c = 92

x=(−bc± sqrt(b^2-4ac))/2a

x=(-(-120)±sqrt((−120)^2−4(36)(92))/2(36)

=120±sqrt(14400−13248−)/72

=120±sqrt(1152)/72

The discriminant b2−4ac>0

so, there are two real roots.

x=(120±24sqrt(2))/72

x=(120/72)±24sqrt(2)/72

Lilly was working on a report on Italian and Spanish scientists. She decided to find a 96 percent confidence interval for the difference in mean age at the time of significant scientific discoveries for Italian versus Spanish scientists. She found the ages at the time of science discovery of all the members of both groups and found the 96 percent confidence interval based on a t-distribution using a calculator. The procedure she used is not appropriate in this context because
The entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.
The sample sizes for the two groups are not equal.
Age at the time of science discovery occurs at different intervals in the two countries, so the distribution of ages cannot be the same.
Age at the time of science discovery is likely to be skewed rather than bell shaped, so the assumptions for using this confidence interval formula are not valid.
Age at the time of science discovery is likely to have a few large outliers, so the assumption for using this confidence interval formula is not valid.
A t statistic was used to conduct a test of the null hypothesis H0: µ = 11 against the alternative Ha: µ ? 11, with a p-value equal to 0.042. A two-sided confidence interval for µ is to be considered. Of the following, which is the largest level of confidence for which the confidence interval will NOT contain 11?
A. A 90% confidence level
B. A 92% confidence level
C. A 96% confidence level
D. A 97% confidence level
E. A 98% confidence level

Answers

Answer:

The answer is "Option A and Option B".

Step-by-step explanation:

In question 1:

In all cases, the entire population is measured so that the actual medium discrepancy could be measured as well as an interval of trust cannot be used.

This issue would be that she calculated the ages with all representatives of both classes, such that she measured a whole population. It's not necessary.

In question 2:

When the p-value is 0.042. At 90% trust and 92% trust level 11 (p-value below 0.10 and 0.08) are not included. however the biggest confidence level of 92%. Consequently, the largest trust level where the 11 is Not included in the trust interval is 92% trust.

Rectangular prism with length of 4 feet, width of 4 feet and height of 4 feet. D. Rectangular prism with length of 11 feet, width of 2 feet and height of 2 feet.

Answers

Answer:

C & D

Step-by-step explanation:

A. = 48 cubic units

B. = 48 cubic units

C. = 64 cubic units

D. = 44 cubic units

The only rectangular prism that does not have a volume of 48 cubic units is C and D, which has a volume of 64 and 44 cubic feet respectively.

What is prism?

A prism is a three-dimensional solid object with two identical ends. It is made up of flat faces, identical bases, and equal cross-sections. The prism's faces are parallelograms or rectangles without bases.

To find the volume of each rectangular prism, you can use the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height.

Rectangular prism with length of 8 feet, width of 2 feet, and height of 3 feet.

V = (8)(2)(3) = 48 cubic feet

Rectangular prism with length 6 feet, width of 2 feet and height of 4 feet.

V = (6)(2)(4) = 48 cubic feet

Rectangular prism with length of 4 feet, width of 4 feet and height of 4 feet.

V = (4)(4)(4) = 64 cubic feet

Rectangular prism with length of 11 feet, width of 2 feet and height of 2 feet.

V = (11)(2)(2) = 44 cubic feet

Thus, the only rectangular prism that does not have a volume of 48 cubic units is C and D.

Answers

Answer:

2.250 feet thick

Step-by-step explanation:

hope it helps mark as brainliest

Answer:

Step-by-step explanation:

The outside diameter minus the inside diameter would leave a difference of TWICE the thickness of the pipe, so divide the difference by 2

Pipe Thickness =  (OD -  ID) / 2  

                           =  (1.275 - 0.975) / 2

                           =   0.3 / 2
