a basketball team won 40 games during a season of 85 games. what is the ratio of win to losses? brainly

Answer:

I believe the answer to this question is: X=square root(39), and square root(-39).

An exterior angle is equal to the sum of the two opposite inside angles.

T + 31 = t + t-29

Simplify:

T + 31 = 2t -29

Add 29 to both sides:

T + 60 = 2t

Subtract 1t from both sides:

T = 60

She will need 191.55 pounds of flour.

Step-by-step explanation:

Given:

Audrey needs 2.4 pounds if flour for birthday cakes and 3.75 pounds of flour for wedding cakes.

If she plans on baking 72 birthday cakes and 5 wedding cakes.

Now, to find pounds of flour will she need.

So, the pounds of flour for 72 birthday cakes:

[tex]2.4\times 72[/tex]

[tex]=172.8\ pounds.[/tex]

And, the pounds of flour for 5 wedding cakes:

[tex]5\times 3.75[/tex]

[tex]=18.75\ pounds.[/tex]

Now, to get the pounds of flour she need we add the pounds of flour to make 72 birthday cakes and 5 wedding cakes:

[tex]172.8+18.75[/tex]

[tex]=191.55\ pounds.[/tex]

Therefore, she will need 191.55 pounds of flour.

Answer:

y = - 5x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Here m = - 5 and b = 7, thus

y = - 5x + 7 ← equation of line

Good morning ☕️

Answer:

Step-by-step explanation:

y=mx+b

m = slope = -5

b = y-intercept = 7

then the equation is : y = -5x + 7

Answer:

x = -43/6

Step-by-step explanation:

To solve this equation, you solve for 'x' by isolating it. This means to move every other number to the other side of 'x'. You can move numbers when they 'cancel' out by doing the opposite (Adding and subtracting are opposites. Dividing and multiplying are opposites).

[tex]\frac{3x-2}{6}-\frac{4x+1}{4} = 3[/tex]

[tex]\frac{3x-2}{6}*\frac{2}{2}-\frac{4x+1}{4}*\frac{3}{3} = 3[/tex]     Multiply each fraction by a fraction that equals '1'. (2/2 = 1 and 3/3 = 1). This will give them a common denominator.

[tex]\frac{(3x-2)*2}{6*2}-\frac{(4x+1)*3}{4*3} = 3[/tex]     Multiply

[tex]\frac{(6x-4)}{12}-\frac{(12x+3)}{12} = 3[/tex]

[tex]\frac{(6x-4)-(12x+3)}{12}= 3[/tex]     Combine the fractions with the same denominator

[tex]\frac{(6x-4)-12x-3}{12}= 3[/tex]     Subtract binomials. -(12x+3) is -12x-3

[tex]\frac{6x-4-12x-3}{12}= 3[/tex]     Remove unnecessary brackets

[tex]\frac{-6x-7}{12}= 3[/tex]     Combined like terms.

[tex]\frac{-(6x+7)}{12}= 3[/tex]     Factor out the negative in the top.

[tex]-(6x+7)= 3*12[/tex]     Multiplied both sides by 12

[tex]-(6x+7)= 36[/tex]     Simplified right side

[tex]6x+7= -36[/tex]     Divided both sides by -1

[tex]6x= -36-7[/tex]     Subtract 7 from both sides

[tex]6x= -43[/tex]     Simplified right side

[tex]x= \frac{-43}{6}[/tex]     Divided both sides by 6. Answer in fraction form.

x = 7.166..67     Answer in decimal form

Therefore x is -43/6 or about 7.17.

Answer: x≈3

Step-by-step explanation:

0.48 = log x , this could also be written as :

[tex]log_{10}[/tex] x = 0.48 , that is

x = [tex]10^{0.48}[/tex]

x = 3.01995172

x≈ 3

The solution to the equation 0.48 = log x is approximately 3.02 after converting it from logarithmic form into exponential form and calculating 10 to the power of 0.48.

To solve the logarithmic equation 0.48 = log x we have to rewrite this equation in exponential form. A logarithm log_b(x) = y in exponential form is represented as b^y = x. Considering that in your question it's not specified, this likely means a base of 10 is being used. Hence, the equation 0.48 = log x can be converted into exponential form: 10^0.48 = x.

Performing the calculation with a calculator (or by hand if you know how), we find x ≈ 3.02. Therefore, the solution for x in the given equation is approximately 3.02.

The x-intercepts appear on this polynomial are 3 x intercepts.

Step-by-step explanation:

To find the x intercepts of the polynomial [tex]f(x)=x^{4} -5x^{2}[/tex] is by equating [tex]f(x)=0[/tex]

Step-by-step explanation:

Final answer:

The sum of the two numbers is 60 and their quotient is 4. Using the substitution method, we find that the two numbers are 48 and 12.

Explanation:

Let's call the two numbers x and y. We're given that the sum of the two numbers is 60, so we can write the equation:

x + y = 60

We're also given that their quotient is 4, so we can write the equation:

x / y = 4

To solve this system of equations, we can use the substitution method. Solving the second equation for x, we get:

x = 4y

Substituting this value of x into the first equation, we get:

4y + y = 60

Combining like terms, we have:

5y = 60

Dividing both sides by 5, we find:

y = 12

Substituting this value of y back into the equation x = 4y, we get:

x = 4(12)

Simplifying, we find:

x = 48

So the two numbers are 48 and 12.

Answer:

2/4, 3/6, 4/8, 5/10, 6/12

Step-by-step explanation:

Equivalent fractions are fractions that have the same value or represent the same part of an object. If a pie is cut into two pieces, each piece is also one-half of the pie. If a pie is cut into 4 pieces, then two pieces represent the same amount of pie that 1/2 did. We say that 1/2 is equivalent to 2/4.

Fractions are determined to be equivalent by multiplying the numerator and denominator of one fraction by the same number. This number should be such that the numerators will be equal after the multiplication. For example if we compare 1/2 and 2/4, we would multiply 1/2 by 2/2 which would result in 2/4 so they are equivalent.

To compare 1/2 and 3/7 we would multiply 1/2 by 3/3 to produce 3/6. Since 3/6 is not the same as 3/7, the fractions are not equivalent.

Fractions equivalent to 1/2 are 2/4, 3/6, 4/8, 5/10, 6/12 ...

Fractions equivalent to 1/3 are 2/6, 3/9, 4/12, 5/15, ...

Fractions equivalent to 1/4 are 2/8, 3/12, 4/16, 5/20, ...

Fractions equivalent to 1/5 are 2/10, 3/15, 4/20, 5/25, ...

Fractions equivalent to 2/5 are 4/10, 6/15, 8/20, 10/25, ...

$ 2000 is invested at 3 % interest and $ 4000 is invested at 8 % interest

Solution:

Given that, total of $6000 was invested

Let "x" be the amount invested at 3 % interest

Then, (6000 - x) is the amount invested at 8 % interest

Given that,

The total yearly interest amounted to $380

Then, we can frame a equation as:

[tex]x \times 3 \% + (6000 - x) \times 8 \% = 380[/tex]

Solve the above expression for "x"

[tex]x \times \frac{3}{100} + (6000-x) \times \frac{8}{100} = 380\\\\0.03x + (6000-x) \times 0.08 = 380\\\\0.03x + 480 - 0.08x = 380\\\\-0.05x = -100\\\\\text{Divide both sides by -0.05 }\\\\x = 2000[/tex]

Thus, $ 2000 is invested at 3 % interest

(6000 - x) = 6000 - 2000 = 4000

$ 4000 is invested at 8 % interest

An algebraic expression that represents 'x squared is less than 15' can be written directly as 'x² < 15', without additional mathematical operations.

Explanation:

The question asks for an algebraic expression that represents the inequality 'x squared is less than 15'. This is straightforward to write and does not require completing the square or solving a quadratic equation. The algebraic expression that correctly represents this inequality is simply x² < 15.

To explain further, the inequality suggests that the square of x (x²) must be less than the value 15. We do not need to perform any additional steps or manipulations like factoring or applying the quadratic formula, as the expression represents a basic inequality in its simplest form.

Answer:

Rayshawn originally had $30.

Step-by-step explanation:

i) Rayshawn has a certain amount of money. Let us say this amount is $x.

ii) Rayshawn spends $20 which means that he is left with $(x - 20)

iii) it is also given that amount of money left after spending $20 is [tex]\dfrac{1}{3}[/tex] of the original amount, $x, the amount remaining is [tex]\dfrac{\$x}{3}[/tex].

iv) from the information given in ii) and iii) we get

     $(x - 20) = [tex]\dfrac{\$x}{3}[/tex],  Therefore we get 3x - 60 = x , therefore 2x = 60,

  Therefore x = $30. Rayshawn originally had $30.

Therefore, Rayshawn had $60 initially.

If Rayshawn spends $20 and ends up with 1/3 of the original amount, we can deduce that $20 represents 2/3 of the original amount.

since 1 - 1/3 = 2/3. Thus, each part (1/3) of the original amount corresponds to $20. Consequently, to find the original amount, we multiply $20 by 3, yielding $60. Therefore, Rayshawn originally had $60. This conclusion emerges from understanding that after spending $20, Rayshawn retains 1/3 of his original funds, implying that the $20 spent was equal to 2/3 of his initial sum. Thus, the inverse operation, multiplying by 3, unveils the original amount. Therefore, Rayshawn had $60 initially.
