1. There are 34 rose bushes currently in the park. Park workers will plant
more rose bushes today.
When the workers are finished there will be 70
rose bushes in the park. How many rose bushes did the workers plant
today?
34 + 70 = x; x = 104
34 - x = 70 ; x = 36
34 + x = 70; x = 36
70 - 34 = x; x= 36
Answer:
34 + x = 70 ; 36
Step-by-step explanation:
Given that:
Current amount = 34
Final amount = 70
Number of roses planted by the workers today ;
Current amount + number planted today = final amount
Let number planted today = x
34 + x = 70
x = 70 - 34
x = 36

Step-by-step explanation:
For the triangle it is given that AE2 + EB2 = 9 and BE2 + EC2 = 16
Find AC =
Answer:
Step-by-step explanation:Given : right triangle ABC , AE^2 + EB^2 =9 and BE^2 + EC^2 = 16
To find : AC
Solution:
BE ⊥ AC
∠AEB = 90°
=> ΔAEB is right angled
=> AB² = AE² + EB²
=> AB² = 9
∠BEC = 90°
=> ΔBEC is right angled
=> BC² = BE² + EC²
=> BC² = 16
∠ABC = 90°
=> AC² = AB² + BC²
=> AC² = 9 + 16
=> AC² = 25
=> AC = 5
AC = 5
The length of AC is 5 units.
What is a Triangle?Any three-sided polygon having three edges and three vertices is referred to as a triangle in geometry. The most important attribute of a triangle is that its internal angles sum to 180 degrees. The triangle's angle sum attribute is what is known as.
As per the given data:
We are given the diagram of ΔABC which is right-angled.
BE is perpendicular to AC.
AE² + EB² = 9 ...(i)
BE² + EC² = 16 ..(ii)
By using the Pythagoras theorem in ΔABE:
AE² + EB² = AB²
From comparing with eq (i)
AB² = 9
AB = √9 = 3 units
By using the Pythagoras theorem in ΔCBE:
BE² + EC² = BC²
From comparing with eq (ii)
BC² = 16
BC = √16 = 4 units
By using the Pythagoras theorem in ΔABC:
AB² + BC² = AC²
AC² = 3² + 4²
AC² = 9 + 16 = 25
AC = 5 units.
The length of AC is 5 units.
Hence, The length of AC is 5 units.

2x-y=60
6y=x
Solve the system using substitution. Check your solution.
Answer:
[tex]x = \frac{360}{11} [/tex]
[tex]y = \frac{60}{11} [/tex]
Step-by-step explanation:
Since 6y=x plug 6y in for x on the top equation.
[tex]2(6y) - y = 60[/tex]
[tex]12y - y = 60[/tex]
[tex]11y = 60[/tex]
[tex]y = \frac{60}{11} [/tex]
Plug y=60/11 into 6y=x
[tex]6( \frac{60}{11} ) = x[/tex]
[tex] \frac{360}{11} = x[/tex]
Plug 360/11 into 2x-y=60
[tex]2( \frac{360}{11} ) - \frac{60}{11} = 60[/tex]
[tex] \frac{720}{11} - \frac{60}{11} = 60[/tex]
[tex] \frac{660}{11} = 60[/tex]
The identity is true

If the weight of 90 books is 50kg, what is the weight of 180 such books. In both proportion and unitary method.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the weight of 90 books is 50kg. We need to get the weight of a book first and this will be:
= 50/90
= 5/9
Therefore, the weight of 180 such books will be 5/9 multiplied by 180. This will be:
= 5/9 × 180
= 100kg

Factor: 3bc-4ad +6ac-2bd
Can you create a rubric for this math question
Answer:
(3c−2d)(2a+b)
Step-by-step explanation:
3bc−4ad+6ac−2bd
Do the grouping 3bc−4ad+6ac−2bd=(6ac−4ad)+(3bc−2bd), and factor out 2a in the first and b in the second group.
2a(3c−2d)+b(3c−2d)
Factor out common term 3c−2d by using distributive property.
(3c−2d)(2a+b)
How many 3-inch thick bags of mulch should Noemi buy to cover 100 square feet at a depth of 4 inches? The length is 3.2ft and the width is 2.5ft.
Answer:
Approximately 17 bags.
Step-by-step explanation:
The length of the bag of mulch = 3.2 ft
The width of the bag of mulch = 2.5 ft
The thickness of the bag of mulch = 3 inch = 0.25 ft
Volume of a bag of mulch = length x width x thickness
= 3.2 x 2.5 x 0.25
= 2 cubic feet
So that, the volume of a bag of mulch is 2 cubic feet.
The area to be covered = 100 square feet
The depth of the area = 4 inches = [tex]\frac{1}{3}[/tex] feet
volume of the portion to be covered = area x depth
= 100 x [tex]\frac{1}{3}[/tex]
= 33 [tex]\frac{1}{3}[/tex] cubic feet
The volume of the portion to be covered is 33 [tex]\frac{1}{3}[/tex] cubic feet.
The number of bags of mulch needed = [tex]\frac{33\frac{1}{3} }{2}[/tex]
= 16[tex]\frac{2}{3}[/tex]
= 16.6667
The number of bags of mulch needed is 17.

What is the result when 12x2-7y2 is added by -10x2+y2?
A.2x2-6y2
B.2x2+6y2
C.-2x2-8y2
D.-2x2+8y2
Answer:
A
Step-by-step explanation:
12x² - 7y² - 10x² + y² = 12x² - 10x² - 7y² + y²
= (12 - 10)x² + (-7 + 1)y²
= 2x² + (-6y²)

if the velocity is big, must there be forces on it?
Answer:
Acceleration and velocity
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

Standard form: a(X-h)²+k = ( -2/3X² -16/3X -32/3) +32/3 -17/3 = -2/3(X +4)² +5
y = -2/3*X^2-16/3*X-17/3
X = -4 ±√( 15/2) = -6.7386, or -1.2614
Axis of symmetry: X= -4; Vertex (maximum)=(h,k)=( -4, 5); y-intercept is (0,-5.66666666667)
two real roots: X=-1.2613872124776866 and -6.738612787477313
Answer:
b) y = -2/3(x + 4)² + 5c) y = 1/2(x + 8)² - 5d) y = 3/8(x + 7)² - 2Step-by-step explanation:
Vertex form is:
y = a(x - h)² + kVertex of the function is point (h, k)
b) Congruent to y = 2/3x² and opens down means:
a = -2/3Maximum value at (-4, 5) means:
h = -4, k = 5The function is:
y = -2/3(x + 4)² + 5c) Congruent to y = 1/2x² and has minimum value y = -5 at x = -8:
a = 1/2, h = -8, k = -5The function is:
y = 1/2(x + 8)² - 5d) Vertex (-7, -2) and passes through the point (-3, 4)
y = a(x + 7)² - 2Substitute coordinates and find a:
4 = a(-3 + 7)² -26 = 16aa = 3/8The function is:
