PLS I NEED HELP i have been stuck on this one for a while

Answer:

x = 24

Step-by-step explanation:

let x be the number we want to determine its value

The statement  x increased by ¼ of itself is equal to 30

is equivalent to :

[tex]x + \frac{x}{4}=30\\\\then[/tex]

[tex]\frac{4x+x}{4} = 30\\\\then[/tex]

[tex]\frac{5x}{4} = 30\\\\then[/tex]

5x = 4× 30

then

5x = 120

then

x = 120/5

then

x = 24

Answer:

[tex]a_{n} = \frac{8}{2^{n-1} }[/tex]

Step-by-step explanation:

A geometric sequence has a constant ratio (r) and is defined by:

[tex]a_n=a_1r^{n-1}[/tex]

Since the first value is 8, [tex]a_{1}[/tex] = 8.

[tex]a_n=8r^{n-1}[/tex]

We can also see that a_n is double that of the next value in the sequence [tex](a_{n} = 2a_{n+1}})[/tex], hence r = 1/2

[tex]a_n=8\left(\frac{1}{2}\right)^{n-1}[/tex]   or

[tex]a_{n} = \frac{8}{2^{n-1} }[/tex]

Answer:

a= 25

Step-by-step explanation:

STEPS FOR SOLVING LINEAR EQUATION

3(a−5)=2(a+5)

Use the distributive property to multiply 3 by a−5.

3a−15=2(a+5)

Use the distributive property to multiply 2 by a+5.

3a−15=2a+10

Subtract 2a from both sides.

3a−15−2a=10

Combine 3a and −2a to get a.

a−15=10

Add 15 to both sides.

a=10+15

Add 10 and 15 to get 25.

a=25

Answer:

C. The likelihood of having brown eyes is 35%

Step-by-step explanation:

Add the total number of people, which gives you 50.

To find the percent of brown-eyed people out of 50, divide 35 by 50, then multiply the result (0.7) by 100 to get 70%.

70% of people are brown-eyed, thus, C is a false statement.

Answer:

the answer is C

Step-by-step explanation:

the brown eyes would be 70 percent actually

Answer:

13.72 cm²

Step-by-step explanation:

The formula to find the area of a shaded region: Area of the bigger shape - area of the smaller shape.

The formula to find the area of a square: [tex]a^{2}[/tex], where [tex]a[/tex] is the side.

The formula to find the area of a circle: [tex]\pi r^{2}[/tex], where [tex]\pi[/tex] is 3.14 or [tex]\frac{22}{7}[/tex] or 3.142 or similar, [tex]r[/tex] is the radius (diameter ÷ 2).

1) Find the area of the circle using the formula. The radius is 4 because the diameter is 8 (8 ÷ 2 = 4).

= [tex]\frac{22}{7}*4^{2}[/tex]

= [tex]\frac{22}{7}*16[/tex]

= 50.285

2) Find the area of the square using the formula.

= [tex]8^{2}[/tex]

= 64

3) Apply: area of the bigger shape - area of the smaller shape.

= 64 - 50.285

= 13.715

4) Round it off to the nearest hundredth.

= 13.72

Answer: 32

Step-by-step explanation:

We know that the original number of paper snowflakes was 36, plus 28 given by her brother. The new total would be 64 paper snowflakes and she only uses half of the paper snowflakes. The answer would be 32.

The value that would be put for r is; 0.063

We are given the monthly payment formula for present value as;

M = (Pr(1 + r)ⁿ)/(1 - r) - 1

Where;

P is Present Value

r is interest rate

n is number of times compounded

Now, we are told the interest rate is given as 6.3% and so we can write that; r = 6.3/100 = 0.063

Answer:

the answer is x>5 please. rate. me. brainliest

Answer:

x>3

x greater then 3 ..........

If u = ⟨-4, 8⟩ and v = ⟨5, -18⟩, then we have

2u - 4v = ⟨-8, 16⟩ + ⟨-20, 72⟩ = ⟨-28, 88⟩

To this vector, we want to add another vector w = ⟨a, b⟩ such that

2u - 4v + w = ⟨0, 1⟩

Solve for w :

w = ⟨0, 1⟩ - ⟨-28, 88⟩ = ⟨28, -87⟩ … … … [C]

Answer:

29 candy bars

Step-by-step explanation:

13 movie pases= $9.50x13= $123.50

3 gift cards= $25×3 =$75

amount of money she has left over to buy candy bars = $250- $75- $123.5 = $51.50

Amount of candy bars she can buy = $51.50÷$1.75 = 29.43 candy bars, but u can only buy full candy bars and there for 29 candy bars is the final answer

Answer:

Option B

Step-by-step explanation:

Given:

To determine the percentage of the production was out of spec, we need to use the percentage formula (x/y × 100).

[tex]\implies \dfrac{x}{y} \times 100[/tex]

The value of "x" is the the number of pieces that were out of spec and the value of "y" is the total pieces in the production results.

[tex]\implies \dfrac{130}{3500} \times 100[/tex]

Simplify the expression to determine the percentage of the pieces that were out of spec.

[tex]\implies \dfrac{13000}{3500}[/tex]

[tex]\implies \dfrac{130}{35} = \dfrac{130 \div 5}{35 \div 5} = \dfrac{26}{7} = 3.714... \%[/tex]

When the percentage is estimated to nearest hundredth, we get 3.71%

(Option B)

Answer:

B)  3.71%

Step-by-step explanation:

[tex]\textsf{130 out of 3500}\sf =\dfrac{130}{3500}[/tex]

To convert to a percentage, multiply by 100:

[tex]\implies \sf \dfrac{130}{3500} \times 100\%=0.03714.. \times 100\%=3.71\%[/tex]
