Sarah is designing a flower garden and has allowed herself $300 for expense. she finds flowers for $6 each and bushes for 10$ each which of the flowing combination of flowers and bushes could Sarah buy considering her budget.
13 flowers and 23 bushes
16 flowers and 21 bushes
8 flowers 26 bushes
25 flowers 14 bushes
Answer:
25 flowers 14 bushes
Step-by-step explanation:
13f/23b = 308
16f/21b = 306
8f/260 = 308
25 · 6 = 150
14 · 10 = 140
140+150 = $290
Sarah can buy 25 flowers and 14 bushes considering her budget.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Let x be the number of flowers and y be the number of bushes.
Total expense = $300
Cost for each flower = $6
Cost for each bush = $10
We get an equation,
6x + 10y = 300
(a) 13 flowers and 23 bushes
Total cost = (6 × 13) + (10 × 23) = $308
(b) 16 flowers and 21 bushes
Total cost = (6 × 16) + (10 × 21) = $306
(c) 8 flowers 26 bushes
Total cost = (6 × 8) + (10 × 26) = $308
(d) 25 flowers 14 bushes
Total cost = (6 × 25) + (10 × 14) = $290
Hence the possible combination is 25 flowers and 14 bushes.

Step-by-step explanation:
the formula for the circumference of a circle is 2rπ
the formula for the area of a circle is (r^2)π
the formula for the diameter of a circle is 2r
π=3.14
---------------------------------------------------------------
1. diameter =2r. since diameter=24, r=12
2. circumference=2rπ. since circumference = 314. 314=2rπ r=49.9746
3. circumference=2rπ area=(r^2)π
since r=7, circumference=14π=43.98229 since r=7, area is 49π=153.9380
4. Since the diameter is 20 the radius is 10. so just insert it into the formulas as before: circumference=20π=62.8318 and area=100π=314.15926
5. the formula for the diameter is 2r=d 2(18)=d, 36=d
6. 2rπ=circumference = 2(5)π=10π=31.415926

The sum of two numbers is 51. The smaller number is 17 less than the larger number. What are the numbers?
Larger number
smaller number
Answer:
smaller number = 17, larger number = 34
Step-by-step explanation:
Let x be the smaller number and y be the larger nuber
x + y = 51 --(1)
y - 17 = x --(2)
Sub (2) into (1)
y - 17 + y = 51
y = 34
Put y = 34 into (2)
34 - 17 = x
x = 17
Ans: smaller number = 17, larger number = 34
Answer:
Let get large number is x and small number as y.
sum of two numbers is 51.(small number + large number = 51)
ie. x +y =51 --------(1)
The smaller number is 17 less than the larger number.
x-y = 17 ------------(2)
(1) +(2);
(x + y ) + (x - y) = 51 +17
2x = 68
x=34
Substituted for (1);
x + y =51
34 + y =51
y= 51 -34
y= 17

A surveyor measured the angle of elevation of a flat spire as 15 degree from a point in horizontal group.He movrs 30m nearer to the flat and measure the angle of elevation at 43 degrees.Calculate the height of the spire to the nearest hundredth.
Answer:
11.28m
Step-by-step explanation:
The computation of the height of the spire is shown below:
let us assume the height of the spire be x
Now
For triangle ABD
Tan 43 degrees = h ÷ x
x = h × cot 43 degrees
= 1.07236 h
For triangle ABC
tan 15 degrees = h ÷ (30 + x)
0.2679 = h ÷ 30 + 1.07236h
8.038 + 0.28728 h = h
h = 11.28m

What number is obtained by increasing by 36 50%
Answer:
54
Step-by-step explanation:
The given number to be increased = 36
The percentage by which the number is increased = 50%
In increasing a number by a percentage, we find the value of the percentage increase of the number and add to the number as follows;
50% of 36 + 36 = 50/100 × 36 + 36 = 54
Second method
The find the number obtained by increasing a number by a given percentage 'x', we add 100 to the give percentage and multiply the result by the number and hen divide the final result by 100 as follows;
36 increased by 50% = (100 + 50) × 36/100 = 54

The area of a rectangular gymnasium is (5x+5x) square feet. If it is 5x feet wide, what is the length, in feet?
A. x + 1
B 5x
0. 12
D
x + x
Answer:
Step-by-step explanation:
Area = L x W gym area is (5x + 5x) ft² if W = 5x Find the L
Area = L x W divide both sides by W
Area/W = (L x W) / W
Area/W = L = Area/W
L = Area/W
= (5x + 5x) / (5x)
= 5x( 1 + 1) / 5x
= 5x(2) / 5x the 5x's cancel each other 5x/5x = 1

Given f(x) = 2x ^ 2 + kx - 20 and the remainder when f(x) is divided by x - 10 is 90, then what is the value of k?
Answer:
k = -9
Step-by-step explanation:
f(x) = 2x²+kx-20
From remainder theorem,
x = 10 and f(10) = 90
f(10) = 90
Subsitute the value of x into the expression above.
f(10) = 2(10²)+10k-20 = 90
200+10k-20 = 90
Solve for k by collecting like terms
10 k = 90+20-200
10k = 110-200
10k = -90
k = -90/10
k = -9.
Hence the value of the constant is -9
