<h2>Answer:</h2>

The solution to the given inequality in interval notation is:

[-4,1]

<h2>Step-by-step explanation:</h2>

From the number line graph that is provided to us we see that the shaded region is to the right of -4 and to the left of -1.

Also, there are closed circles at -4 and -1.

This means that the solution set is the set of all the real values between -4 and -1 inclusive.

( If there would be open circles at -4 and -1 then those would not be included in the solution set )

i.e. in interval form the solution set is:

[-4,-1]

Erica’s family is moving away from California. They decided to have a moving sale and sell each item for 70% off the price they

Burka [1]

Find the sale price by multiplying the original price by 70% then add the two prices together to get the total.

799 x 0.70 = 559.30

549 x 0.70 = 384.30

Total: 559.30 + 384.30 = $943.60

Find the volume and surface area of the square pyramid

Montano1993 [528]

The volume and surface area of the pyramid will be 392 / 3 cubic units and 189 square units. Then the correct option is A.

The complete question is attached below.

<h3>What is the volume and surface area of the pyramid? </h3>

Suppose the base of the pyramid has length = L units, width = W units, slant height = K units, and the height of the pyramid is of H units.

Then the volume of the pyramid will be

V = (L × B × H) / 3

The surface area of the pyramid will be

SA = 2(1/2 × B × K) + 2(1/2 × L × K) + (L × B)

Then the volume will be

V = (7 × 7 × 8) / 3

V = 392/3 cubic units

Then the surface area will be

SA = 2(1/2 × 7 × 10) + 2(1/2 × 7 × 10) + (7 × 7)

SA = 189 square units

Then the correct option is A.

More about the volume and surface area of the pyramid link is given below.

Clara has a lawn in front of her house as mapped on the coordinate plane. She wants to plant a bed of flowers between the points

Hunter-Best [27]

Answer:

<em>Look Below In the Explanation</em>

Step-by-step explanation:

Point P has coordinates of (4,4) and point Q has coordinates of (4,-4).

Since both points have the same x-coordinates we can subtract point Q's y-coordinate from point P's y-coordinate.

I will set the equation up and try and figure this part by yourself. I hope you learned what to do from previous questions that are very similar to this that I answered.

4 - ( -4) = length of the bed of flowers

Hope that helps and maybe earns a brainliest!

Have a splendid day! :^)

Question 5 of 10

True [87]

Answer:

The median value of the houses is $169,000

Step-by-step explanation:

Since the houses were undervalued by $15,000, add $15,000 to all amounts

154,000 + 15,000 = 169,000

133,000 + 15,000 = 148,000

167,000 + 15,000 = 182,000

145,000 + 15,000 = 160,000

180,000 + 15,000 = 195,000

172,000 + 15,000 = 187,000

149,000 + 15,000 = 164,000

To take the median of the data set, order the numbers from least to greatest

148,000 160,000 164,000 169,000 182,000 187,000 195,000

Eliminate one number from both sides until you reach one number

The number is 169,000
