Answer:

pls mark brainliest if possible

Step-by-step explanation:

the range is the difference between the values of the largest and smallest values. You can figure this out with subtraction.

Largest number: 100

Smallest number: 80

Range: 20

C1V1 = C2V2
0.48×8L = C2(10L)
C2 = (3.84)/10 = 0.384 = 38.4% sugar

Its me arg i need help

Alex787 [66]

Answer:

x=8

Step-by-step explanation:

so since the whole thing should equal 180, and the right triangle is 90,

(3x+11)+(5x+15)=90 then solve for that

8x+26=90

8x=64

divide both sides by 8

so x=8

then plug in 8 for the xs so c is 3(8)+11 --> 24+11 so m<C=35*

m<D=90*

5(8)+15 40+15 so m<E=55

The second term in a geometric sequence is 12. The fourth term in the same sequence is 4/3. What is the common ratio in this seq

VARVARA [1.3K]

Answer:

The common ratio in the sequence is 1/3

Step-by-step explanation:

?, 12, ?, 4/3

12 * 1/9 = 4/3

The 1/9 is divided across two spaces.

1/9 = x²

x = 1/3

12 * <u>1/3</u> = 4

4 * <u>1/3</u> = 4/3

Answer:

$143.8\:\mathrm{ft^2}$

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): $\frac{1}{2}\cdot 4.5^2\cdot \pi$

Area of trapezoid (average of bases multiplied by height): $16\cdot 7$

Thus, the total area of the figure is:

$\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}$
