Rosalie has 30 plants in her garden

<h3><u>Solution:</u></h3>

Given that Elizabeth has 1\frac{7}{10} as many plants as Rosalie has in her garden

Also given that Elizabeth has 51 plants

Let "a" be the number of plants in Elizabeth garden

Let "b" be the number of plants in Rosalie garden

So according to given information,

Number of plants in Elizabeth garden = 1\frac{7}{10} \times number of plants in rosalie garden

a = 1\frac{7}{10} \times b\\\\51 = \frac{17}{10} \times b\\\\51 = 1.7 \times b\\\\b = \frac{51}{1.7}\\\\b = 30

Thus number of plants in Rosalie garden is 30

nordsb [41]

9514 1404 393

Answer:

  A.  2 square feet

  B.  draw a diagonal; 1 square foot

Step-by-step explanation:

A. The area of a parallelogram is given by the formula ...

  A = bh

Here the base (b) is 3 feet, and the height (h) is 2/3 ft. The area is ...

  A = (3 ft)(2/3 ft) = 2 ft^2 . . . . area of the parallelogram

__

B. <em>Drawing a diagonal</em> (AC or BD) will divide the figure into two congruent triangles. Each triangle has the same base and height as the original parallelogram. The area of one of the triangles is given by ...

  A = 1/2bh

Using the given dimensions, ...

  A = 1/2(3 ft)(2/3 ft) = 1 ft^2 . . . . area of one triangle

Solve the following multiplication and division problems.
algol13

Answer:

a. 22.5 km

b. 267.52 m

c. 95 m

d. (4.2)(10^{-5}) km

Step-by-step explanation:

a. You can convert from hectometers to kilometers, and then you can make the multiplication:

\frac{5hm}{10}=0.5km

(3km)(0.5km)(15)=22.5km

b. You can convert from centimeters to meters, and then you can make the multiplication:

\frac{44cm}{100}=0.44m\\(19m)(0.44m)(32)=267.52m

c. You only need to divide 1,140 meters by 12:

\frac{1,140m}{12})=95m

d. You can convert from hectometers to kilometers, from decameters to kilometers and from meters to kilometers, and divide this by 15:

\frac{6hm}{10}=0.6km

\frac{7dam}{100}=0.07km

\frac{5m}{1000}=0.005km

\frac{(3km)(0.6km)(0.07km)(0.005km)}{15}=(4.2)(10^{-5}) km

Hey yall so im taking a test and imm very confused on hwo to find the letter n for the equation
kotegsom [21]

Answer:

n = -7,6

Step-by-step explanation:

n(n+1)+3=45

distributive property: a(b+c) = ab+ac

n²+n+3 = 45

n²+n -42 = 0

factor now

(n+7)(n-6) = 0

n = -7,6
