In a parallelogram, the diagonals bisect each other.
That being the case,
6x = 72

x = 12

AND

x-5 = y
72 -5 = 67

y=67
x = 72

and the diagonals measure
144 and 134

ASHA 777 [7]

Answer:

X = 20 and Y = 5

Step-by-step explanation:

you're supposed to substitute the numbers it so the problem x * 2 also means 10 * 2 because x = 10 and y * 1 also means 5 * 1 because y = 5

The aircraft A330 flies at an average speed of 400 miles per hchor. The expression, 400t gives the distance traveled by the airc

Olenka [21]

The expression:

$d(t)=400t$

gives the distance traveled by the aircraft in t hours, so, for t = 6:

$\begin{gathered} t=6 \\ d(6)=400(6) \\ d(6)=\frac{2400mi}{h} \end{gathered}$

Carlita will visit 14 cities

Tanya [424]

Answer:

$52091.95

Step-by-step explanation:

From the given information:

The number of cities visited = 14

Cost of each cooking demonstration = $3450

The total cost of cooking demonstration = $3450 × 14

= $48300

Book signing material = $1475

∴

The total cost of cooking demonstration and book material is:

= $48300 + $1475 = $49775 ---- (i)

Total meter traveled in visiting 14 cities = 240 * 13 = 3120 miles

However; suppose the weekly rental fee fine = $x &

the change per mile = $y

Then

y*540 + x = 1188.15 --- (ii)

y*880 + x = 1310.55 --- (iii)

From equation (ii) and (iii)

y *340 = 122.4

y = 122.4/340

y = 0.36

From (ii)

y × 540 + x = 1188.15

(0.36)540 + x = 1188.15

x = 1188.15 - (0.36)540

x = 993.75

Hence, the total cost of travelling by RV camper = $1993.75 + 3120 × (0.36)

= $2116.95

Thus, the total amount the publisher should budget = $49975.0 + $2116.95

= $52091.95

!/8 pound of fertilizer covers 25 square feet of ground, how much fertilizer, in pounds, is needed to cover 1 square foot ground

suter [353]

Answer:

1/200 pounds

Step-by-step explanation:

Given ratio

1/8 pound ⇔ 25 square feet

To find

x ⇔ 1 square foot

Divide both sides by 25

1/8÷25 pounds ⇔ 25÷25 square feet
1/200 pounds ⇔ 1 square foot
