Answers

Answer 1

Answer:

320 boys; 480 girls

Step-by-step explanation:

Here is the correct system of equations you can write for this equation:

1.5x=y

x+y=800

x+1.5x=800

2.5x=800

x=320

320+y=800

y=480

-11 cuz 7+4 is 11 and since they both negative, 11 will be negative

Answer:

-11

Step-by-step explanation:

This is the answer because:

1) First, multiply the negative sign with the positive sign.

Negative x Positive = Negative

Equation: -7 - 4

2) Now, multiply the negative sign with the negative sign.

Negative x Negative =  Positive  

Equation: 7 + 4 = 11

3) Finally, add the greater number's sign (-7) in front of the number.

Nate and his brother are saving money to buy a gaming system. The system they want cost $349. The store is having a sale and the system is 30% off. State sales tax 6%.

Answers

Answer:

Step-by-step explanation:

%30 = 0.3

%6   = 0.06

so..

349 - (349 × 0.3)

349 - 104.7

244.3

then do the tax which is %6 or 0.06

244.3 + (244.3 × 0.06)

Find Mx, My, and (x, y) for the lamina of uniform density rho bounded by the graphs of the equations. y = x2/3, y = 0, x = 1

Answers

The required value for the lamina of uniform density [tex]\bar x\\[/tex] and  [tex]\bar y[/tex] are written below,

[tex]\bar x = \dfrac{5}{8}\\[/tex]

[tex]\bar y = \dfrac{5}{14}[/tex]

Given that:

The density of lamina: ρThe graph for the lamina: [tex]y = x^{\frac{2}{3}}[/tex], y = 0, and x = 1

Calculus's core idea of integration entails determining a function's integral. It is a reverse process of differentiation that enables us to compute cumulative numbers, find the area under a curve, solve differential equations, and more.

The function can be written as,

[tex]m = \rho\int_0^1x^{\frac{2}{3}}dx\\= \rho\left[\dfrac{x^{\frac{5}{3}}}{\frac{5}{3}}}\right]\\=\dfrac{3}{5}\rho[/tex]

The value of Mx can be calculated as,

[tex]M_x = \rho\int_0^1\dfrac{x^{\frac{2}{3}}}{2}}\times x^{\frac{2}{3}}dx\\=\dfrac{\rho}{2}\left[\dfrac{x^{(\frac{2}{7})}}{\frac{7}{3}}\right]_0^1\\=\dfrac{3}{14}\rho[/tex]

Calculate the value of My,

[tex]M_y =\rho \int_0^1 x\times x^{\frac{2}{3}}dx\\=\rho \left[\frac{x^\frac{8}{3}}{\dfrac{8}{3}}\right]\\=\dfrac{3}{8}{\rho[/tex]

The value of [tex]\bar x\\[/tex] will be calculated as,

[tex]\bar x = \dfrac{M_x }{m}\\=\dfrac{ \dfrac{3}{8}\rho}{\dfrac{3}{5}\rho}\\=\dfrac{5}{8}[/tex]

The value of [tex]\bar y\\[/tex] is calculated as,

[tex]\bar y= \dfrac{M_y }{m}\\=\dfrac{ \dfrac{3}{14}\rho}{\dfrac{3}{5}\rho}\\=\dfrac{5}{14}[/tex]

Therefore, the required values are [tex]\bar x = \dfrac{5}{8}\\[/tex] and  [tex]\bar y = \dfrac{5}{14}[/tex].

What is Subtraction?

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Here, we have,

given that,

The sum of two numbers is 49

and the difference between these two numbers is 9.

let, the numbers are x & y

so, we get,

according to question:

x+y = 49 ...1

x-y = 9 ....2

so, simplifying we get,

2x = 58

or, x = 29

so, we get,

y = 20

Hence, The solution is, the numbers are 20 and 29.

Answers

Answer:

The first graph , y=x³ is a cubic function graph and that of the second graph, y = 3(x – 4)3 + 7 is a linear graph.

Step-by-step explanation:

The graph of y=x³ is a cubic function graph where the x term has the highest power of x as 3. As attached in the first graph.

The second graph for y = 3(x – 4)3 + 7. is a linear graph that can be written as;

y=(3x-12)3 +7

y=9x-36 + 7

y=9x - 29

which is a linear graph with a slope of 9 and cuts the y-axis at -29 as shown in the second attached graph.

How do i turn 80% 0f 86- i know the answer but i don't know how to do it

Can someone please teach me

Answers

We know that of refers to multiplication (from BODMAS)

% means per hundred, i.e., 1/100

So, 80% of 86 is:

(80/100) × 86

or (4/5) × 86

or 4 × 17.2

or 68.8

Hope you understand

Answer:

68.8

Step-by-step explanation:

Let x be 80% of 86.

To find 80% of 86

[tex] \frac{80}{100} = \frac{x}{86} [/tex]

[tex]80 \times 86 = 100x[/tex]

[tex]6880 = 100x[/tex]

[tex]68.8 = x[/tex]

Or you can simply do it as:

[tex]86 \times 80\%[/tex]

[tex]86 \times \frac{80}{100} [/tex]

[tex] \frac{86 \times 80}{100} [/tex]

[tex] \frac{6880}{100} [/tex]

[tex]68.8[/tex]
