Answers

Answer 1

Answer:

hi

Step-by-step explanation:

et the number of feet they are going to expand the width and length of the patio. ... But, we also know form our problem that they want to increase the total area of the patio by 160 ... Now we can equate the expanded area of the patio and simplify: ... Write the quadratic equation in standard form: x^2- 1 = -7x.

multiply 7

7d^2

Answer: choice A) [tex]7d^2[/tex]

This is the same as writing 7d^2

==================================================

Explanation:

When we add a number to itself repeatedly, we can use multiplication to shorten things. For example: 3+3+3+3 = 5*3 = 15. We have five copies of '3' being added, which explains the 5 times 3.

Extending this idea leads us to shortening repeated multiplications into exponentiations. In the case of [tex]7*d*d[/tex], we have two copies of 'd' being multiplied. We replace [tex]d*d[/tex] with [tex]d^2[/tex] which is the same as d^2. The ^ symbol means "exponent".

The exponent (2) tells us how many copies of the base (the term d) we multiply out.

Another example would be [tex]d^3 = d*d*d[/tex]

So that's why [tex]7*d*d = 7d^2[/tex]

Question 1
Part A

Write an inequality that represents the sentence "y is less than 3
then Graph the inequality on the number line.

Answers

Answer:

Step-by-step explanation:

y < 3

<__|__|__|__|__|__°__|__|__|__>

   -2   -1   0   1    2   3   4   5   6

Basically, for the number line, there is an open circle on the 3 and the line goes to the left of 3.

Here is a true statement: -6.7 < -6.2. Select all of the statements that are equivalent to -6.7 < -6.2.
Group of answer choices

-6.7 is further to the right on the number line than -6.2.

-6.2 is further to the left on the number line than -6.7.

-6.2 is less than -6.7.

-6.2 is greater than -6.7.

-6.7 is less than -6.2.

-6.7 is greater than -6.2.

Answers

2 Answers: Choice D and choice E

=============================================================

Explanation:

Let's go through the answer choices one by one to see which are true and which are false.

A) This is false because -6.7 is to the left of -6.2 on the number line.B) This is false for similar reasoning as choice A.C) This is false because -6.7 < -6.2 means that -6.7 is the smaller value.D) This is true. The value -6.2 is larger than -6.7; we can say that -6.7 < -6.2 is the same as -6.2 > -6.7 (note the two sides swap places and the inequality sign flips).E) This is true and it's directly from -6.7 < -6.2; the inequality sign has the pointed edge aimed at the smaller value, while the non-pointed side is aimed at the larger value. You can think of an alligator's mouth that represents the < sign. The alligator will eat the larger value each time, so this is where the mouth faces.F) This is false since it contradicts choice E above. I recommend drawing out a number line to help see why -6.7 < -6.2 is a true statement.

Answers

Answer:

Step-by-step explanation:

[tex]tan33=544/x\\ \\ x=\frac{544}{tan33}m\\ \\ x\approx 837.7m[/tex]

9514 1404 393

Answer:

  999 meters

Step-by-step explanation:

The length of the lift line represents the hypotenuse of a right triangle. The side opposite the given angle is the height of the mountain. The applicable trig relation is ...

  Sin = Opposite/Hypotenuse

We want to find the hypotenuse, so we use the rearranged form ...

  hypotenuse = (mountain height)/sin(33°)

  lift length = (544 m)/sin(33°) ≈ 998.83 m

The length of the lift from bottom to top is about 999 meters.

Answers

Answer:

0.3

Step-by-step explanation:

Answer:

3/10

Step-by-step explanation:

1. find the lowest common denominator which is 10.

2. for 4/5 you have to multiply 5 by 2 in order to get 10, so you multiply the numerator by 2 as well which gives you 8/10.

3. for 1/2 you have to multiply 2 by 5 in order to get 10, so you multiply the numerator by 5 also which gives you 5/10

4. you work out the difference between both numerators which is 3 and keep the denominator the same
