Answer:

0.64m squared

Step-by-step explanation:

Surface area is the area of the sides added together

I am going to assume that the bottom is a square

0.4 multiplied by 0.6 is 0.24

0.24 halved is 0.12

0.12 multiplied by 4 is 0.48

0.4 multiplied by 0.4 is 0.16

0.48 plus 0.16 is 0.64

Answer:

0.64 m²

Step-by-step explanation:

Total Surface Area : Area (4 triangles) + Area (square)

4 x 1/2 x 0.4 x 0.6 + (0.4)²
2 x 0.24 + 0.16
0.48 + 0.16
0.64 m²

Find the length of QP given Q is the midpoint of XF, PQ =2X+1, XF=7X-4, PF=X

nadezda [96]

Answer:

Therefore the length of QP = 3.4 units

Step-by-step explanation:

Given:

PQ = 2x + 1

XF = 7x - 4

PF = x

Q is the mid poimt of XF

∴ XQ = QF

QF = PQ - PF ..........( Q - F - P )

= 2x + 1 - x

∴ QF = x + 1

∴ XQ = QF = x + 1

TO Find:

QP = ?

Solution:

By Addition Property we have

$XP = XQ + QF+PF ..........(X-Q-F-P)\\\\$

$XF + PF =XQ + QF+PF ..........(X-Q-F-P)\\$

Substituting the given values in above equation we get

(7x - 4) + x = (x +1) + (x +1) + x

8x -4 = 3x +2

8x - 3x + 4 + 2

5x = 6

∴ $x = \frac{6}{5}$

Now we require

QP = (2x + 1)

∴ $QP = 2\times \frac{6}{5} +1\\\\QP = \frac{12+5}{5} \\\\QP =\frac{17}{5} \\\\\therefore QP = 3.4\ unit$

Therefore the length of QP = 3.4 units

Morgan begins biking south to the park at 20mph at noon. Corona leaves from the same point 15 min (.25hr) later to catch her. Ho

garri49 [273]

Answer:

X = 1h15mins

Step-by-step explanation:

Rate Time Distance

Morgan 20 X 20X

Corona 25 X – ¼ 25(X – ¼)

If they meet each other, they need to travle the same distance, mean :

20X = 25(X – ¼)

X = 1.25

The measure of angle B is 65.8°. find the measure of the complement and supplement of angle B.

viktelen [127]

Answer:

The fourth choice

24.2° and 114.2°

Step-by-step explanation:

Complementary angles add up to 90°

Supplementary angles add up to 180°

*a trick to remember this is to know that C is before S in the alphabet, and 90 is before 180, so Complementary is 90 and Supplementary is 180

Step 1: Find the complementary angle

Take 90° and subtract the give angle to find the angle you would need...

90° - 65.8° = 24.2°

Step 1: Find the supplementary angle

Take 180° and subtract the give angle to find the angle you would need...

180° - 65.8° = 114.2°

If the cost of producing a product that sells for $50 is 120,000 plus $20.00 per piece, then how many products must be sold to b

Vadim26 [7]

Let
x--------->number of products
y1--------> the cost of producing a product
y2------> the cost of sell a product

we know that
y1=120,000+20x-------> equation 1
y2=50x------> equation 2

equate equation 1 and equation 2
120,000+20x=50x
50x-20x=120,000
30x=120,000
x=4000

the answer is
4000 pieces
