-0.03x^2+1.53x=0

how would i go about solving for x?

Step-by-step explanation:

x × x = 49 there are two values for x

1) 7 because 7 × 7 = 49

2) -7 because -7 × -7 = 49 the square value for negative numbers is positive.

Answer:

6 hours

Step-by-step explanation:

Let both of them plan for  t hours to plant 111 trees n t hours

Melissa  can plants 10 trees in 1 hour

in t hours she can plant 10 t trees

Jane plants 17 tree in 2 hours

in one hour Jane can plant 17/2 trees

in t hours she can plant (17/2)t  trees.

Total trees planted by both of them in t hours in terms of t will be

10t + (17/2)t

= (10t*2 + 17t)/2

= (20t + 17t)/2

= 37t/2

but it is given that they planted 111 trees together

so 37t/2 should be equal to 111

37t/2 = 111

=> 37t = 111*2 = 222

=> t = 222/37 = 6.

Thus, it takes 6 hours for both of them to plant 111 trees together.

Answer:

The first pair.

Step-by-step explanation:

3 corresponding parts must be congruent for two triangles to be congruent. The first pair has 3 congruence markings; two angles and one side are congruent. Additionally, they are congruent by the ASA postulate because two angles and the included side are congruent.

Answer:

40

Step-by-step explanation:

To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:

C = 2M + 7

(Variables are representative of the first letter of each name)

Seeing as Christopher scored 87, we can put that into the equation and solve for M.

So, the equation will be:

87 = 2M + 7

Subtract 7 from both sides in order to isolate variable M on the right side.

80 = 2M

Now solve for M, which is 40 (divide both sides by 2).

Answer to the question:

Answer:

[tex] \boxed{p = 4} [/tex]

Step-by-step explanation:

[tex] = > {p}^{2} = 16 \\ \\ = > {p}^{ \cancel{2}} = {4}^{ \cancel{2}} \\ \\ = > p = 4 \\ \\ \\ OR \\ \\ \\ = > {p}^{2} = 16 \\ \\ = > {p}^{2} = {4}^{2} \\ \\ = > p = \sqrt{ {4}^{2} } \\ \\ = > p = {4}^{ \cancel{2} \times \frac{1}{ \cancel{2}} } \\ \\ = > p = 4 [/tex]

Using the given equation, we know that the square root of p = 16.

Because of this, we also know that the square root of 16 will equal p.

[tex]\sqrt{16} = 4[/tex]

Therefore, p is equal to 4, or p = [tex]\sqrt{16}[/tex].

Answer:

3. 10m

4. 14m

Step-by-step explanation:

Angle inequality rule: A triangle can only form if it's 2 shortest sides add up to have MORE length than it's longer side.

1. 23 m

2. 4m

3. 10m

4. 14m

5. 7m

1 doesn't follow the angle inequality rule.

2 doesn't follow the angle inequality rule.

3 can be the third side.

4 can be the third side

5 doesn't follow the angle inequality rule.

Solution,

Principal (P)=$4.62

Rate(R)=7%

Time(T)=2 years

Interest (I)=?

Now,

Interest=P*T*R/100

= 4.62*7*2/100

=64.68/100

=$0.6468

Answer:

Is the time in the graph drawn?

Step-by-step explanation:

Answer:

Step-by-step explanation:

Total surface area of a cone [tex]S[/tex] = [tex]\pi r^{2}+\pi rl\\[/tex]

Since the diagram is half of a cone, its surface area will be [tex]S = \frac{\pi r^{2} +\pi rl}{2}[/tex]

r = radius of the cone

l = slant height

From the diagram diameter of the cone = 16m;

r = 16/2 = 8m

l = 17m

[tex]S = \frac{\pi (8)^{2} +\pi (8)(17)}{2}\\S = \frac{64\pi + 136\pi }{2} \\S = 32\pi + 68\pi \\S = 100\pi cm^{2}[/tex]

Answer:

7.2

Step-by-step explanation:

The radius of the circle is 14.

The length of the chord is 12.

Half the length of the chord and radius form a right angled triangle as shown in the diagram below.

We need to find one of the sides of the triangle, d in the diagram.

Using Pythagoras rule:

[tex]14^2 = 12^2 + d^2\\\\196 = 144 + d^2\\\\d^2 = 196 - 144 = 52\\\\d = \sqrt{52} = 7.2[/tex]

The distance between the chord and the center of the circle is 7.2

Answer: 4sqrt10

Step-by-step explanation: The Chord is 12 so half the chord is 6 so the base is 6 and the radius is the hypotenuse, which is 14. and the distance is the missing leg.

so 14^2=6^2+x^2

196=36+x^2

sqrt160=x

to calculate mean add all the entries in a week ,then divide by 7(the number of days)

i give you hint

mean for week 1=(52+65+...   +60)/7

Answer:

The answer is B. In step one he should have added 3 negative x-tiles to both sides.

See attachment for complete question.

Answer:

The correct option is B.

In step one he should have added 3 negative x-tiles to both sides.

Step-by-step explanation:

Given the equation

3x + 1 = 4x + (-4)

Adding 3 negative x tiles, we have

3x + 1 + (-3x) = 4x + (-4) + (-3x)

1 = x - 4

x = 1 + 4 = 5

The value of the given expression √121 + ∛125 would be 16 which is determined by the square root and cube root properties.

Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.

The expression below which is given in the question

⇒ √121 + ∛125

Here 11×11 = 121 and 5×5×5 = 125

⇒ √(11×11) + ∛(5×5×5)

By the square root and cube root properties to get

⇒ 11 + 5

Apply the addition operation,

⇒ 16

Thus, the value of the given expression √121 + ∛125 would be 16.

Answer:

250 girls in the school and 370 students all total

Step-by-step explanation:

250 girls are in the school and 390 total students in the school.

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

The ratio of boys to girls in a school is 12:25

Let, No. of boys in the school = 12x

No. of girls in the school = 25x

Total students in the school = 12x+25x = 39x

Given, there are 120 boys

So, 12x = 120

x = 10

No. of girls in the school = 25x = 25(10)

No. of girls in the school = 250

Total students in the school = 39x = 39(10)

Total students in the school = 390

Hence, 250 girls are in the school and 390 total students in the school.

Answer:

-13

Step-by-step explanation:

(5+1)²-(11+3²)÷4

(6)-14^2 divided by 4

36-14^2/4

13-196/4

13-49

-13

Answer & Step-by-step explanation:

(5 + 1)² - (11 + 3²) ÷ 4

Following the rules of order of operation, the first thing we have to do is the operations in the parentheses ().

(6)² - (11 + 3²) ÷ 4

Next, solve for your exponents.

36 - (11 + 9) ÷ 4

Next, do the operations in the parentheses ().

36 - (20) ÷ 4

Now, divide -20 by 4.

36 - 5

Subtract 5 from 36.

Answer: H' = (-4, 4)

Step-by-step explanation:

H = (-4, -4)

reflect across y = -2:

H is 2 units below y = -2 so when reflected it will be 2 units above y = -2

--> the x-coordinate doesn't change    the new y-coordinate is: 0

H' = (-4, 0)

reflect across y = 2:

H' is 2 units below y = 2 so when reflected it will be 2 units above y = 2

--> the x-coordinate doesn't change    the new y-coordinate is: 4

H'' = (-4, 4)
