Answer:
Option (3). 0.25(22 - d) + d = 10.75
Step-by-step explanation:
Total number of coins Giuliana has = 22
Let the number dollar coins Giuliana has = d
Number of quarters with Giuliana = (22 - d)
Value of dollar coins and quarters = $10.75
So the equation will be,
Number of dollars coins × $1 + Number of quarters × $0.25 = $10.75
d + 0.25 × (22 - d) = 10.75
Therefore, to determine the number of dollars with Giuliana equation will be used,
d + 0.25(22 - d) = 10.75
Option (3) will be the answer.
the shape of christina’s garden is a rectangle
and trapezoid. The rectangle has a dimensions of 4 units by 2 units. The trapezoid
upper base is 8 units and the lower base is 4 units and the height is 2 units
Area of the garden = area rectangle + area
trapezoid
A = (LW) + 0.5( base1 + base2)(h)
A = ( 4 x 2) + 0.5 ( 8 + 4) (2)
A = 20 sq units
Number of carrots = 20 sq units x 15 carrots/
sq units
<span>= 300 carrots</span>
B about 4,000 because 6,963 rounds to 7,000 and 3,098 rounds to 3,000 - 7,000-3,000= 4,000
Answer:
y = -0.904, 19.904
Step-by-step explanation:
f(y) = 9
f(y) = sqrt(y + 99)
-------------------------------------------
9 = sqrt(y +99) - y
81 - 18y + y^2= y + 99
-19y + y^2 = 18
y(y - 19) = 18
y = -0.904, 19.904
(I used a calculator to solve those values)
