Answer:

Grant's weekly allowance is $20.

Step-by-step explanation:

We know that Grant ended with $15. We can say that Grant's weekly allowance is x.

x/2 + 5 = 15

Now to solve:

x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)

x/2 = 10

x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)

x = 20

Grant's weekly allowance is $20.

Answer:

the degree of the function is 8

Step-by-step explanation:

        (f º g º h)(x) = [tex]f(g(h(x)))[/tex]

first lets evaluate g(h(x))

         [tex](x^4 + 2x^3)^2 - 4(x^2 + 2x^3)[/tex]

simplify

        [tex]x^8 + 4x^3 + 4x^6 - 4x^4 -8x^3[/tex]

        [tex]x^8 + -4x^3 + 4x^6 - 4x^4[/tex]

you can easily see that the highest power term is 8 meaning the degree of the function is 8

The categories that are graphed on a circle usually represent the percentage. Option C is correct.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
A circle graph represents the percentage fraction, and a pie chart is the form of a circle graph, Where a whole circle represents the 100% composition of the entities and data set.

Thus, the categories that are graphed on a circle usually represent the percentage. Option C is correct.

Answer: The slope is 2/3, y=2/3x+1

Step-by-step explanation: The 2 points, (3,3) and (6,5), use the method y2-y/x2-x1. Then you find the slope that way, then use point slope form for the slope intercept form: y-y1=m(x-x1), then substitute and solve to get y=2/3x+1

Answer:

Real distance = 84 meter

Step-by-step explanation:

Given:

Map distance = 6 inches

Map scale 1/4 inch = 3.5 m

Computation:

0.25 inches = 3.5 m

Computation:

Real distance = 6/0.25[3.5]

Real distance = 24[3.5]

Real distance = 84 meter

Answer:

4-3(2-x) < 10+x

4 -6 +3x< 10 + x

-2 +3x< 10 +x

2x< 12

x<6

↣ First we solve the Inequality.

[tex]4-3(2-x)<10+x[/tex]

[tex]4-6+3x<10+x[/tex]     ↣ Distribute -3 in (2-x) for easier in solving.

[tex]3x-2<10+x\\3x-x<10+2\\2x<12\\x<6[/tex]

Thus, the answer is x < 6.

↣ Therefore, the greatest possible Integer value of x is 5.

Total no of cards = 20

The ratio of animal cards to fruit cards is 2:3

No of animal cards = 20

Solution,

Let there are 2x animal cards and 3x fruit cards. ATQ,

2x+3x = 20

5x = 20

x = 4

Animal cards = 2x

= 2(4)

= 8

Fruit cards = 3x

= 3(4)

= 12

It is also mentioned that, of the cards, 1/3 have bananas on them. It means,

[tex]B=\dfrac{1}{3}\times 12\\\\=4[/tex]

Hence, 4 cards have bananas on them.

The domain on which of the following function is increasing is [0,4].

Given:

The graph of a function.

To find:

The domain on which of the following function is increasing.

Domain is the set of x-values or input values.

From the given graph it is clear that the vertex of the given function is at (4,75).

Before the point (4,75) the graph is increasing and after the point (4,75) the graph is decreasing.

The function is defined for 0≤x≤9 .

Since the graph is increasing when  0≤x≤4 , therefore the function is increasing over the interval [0,4].

Therefore, the domain on which of the following function is increasing is [0,4].

What is domain?

The domain is the value that x can take from a given function and codomain is the value of y from a function.

Answer:

B: 22.5 degrees

Step-by-step explanation:

The interior angles of a pentagon add up to 540 degrees

(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)

So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60

Unless I read the problem wrong, 60 degrees is the answer which is not an option :P

Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.

The total would be 24x = 540, and so x = 22.5

Multiply by 100

Step-by-step explanation:

The equation is given as:

-m + 0.02 + 2.1m = -1.45 - 4.81m

To eliminate the decimals from all the terms, we must multiply by a number that make all the coefficients integers.

The decimal coefficients and independent terms are

0.02, 2.1, 1.45, 4.81

Note the maximum number of decimals found in all of them is 2. Thus, multiplying by 100 all the decimals will vanish as follows:

100(-m + 0.02 + 2.1m) = 100(-1.45 - 4.81m)

-100m + 2 + 210m = -145 - 481m

Now all terms have integer coefficients as required.

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

[tex]\left(5.91\times \:10^{-3}\right)-\left(8.7\times \:10^{10}\right)[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]

[tex]=5.91\times \:10^{-3}-8.7\times \:10^{10}[/tex]

as

[tex]5.91\times \:10^{-3}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]

[tex]=5.91\times \frac{1}{10^3}[/tex]

[tex]=\frac{5.91}{1000}[/tex]

[tex]=0.00591[/tex]

similarly

[tex]8.7\times \:10^{10}[/tex]

Convert element to a decimal form

[tex]10^{10}=10000000000[/tex]

so

[tex]=10000000000\times \:8.7[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:8.7\times \:10000000000=87000000000[/tex]

[tex]=87000000000[/tex]

Thus, the expression becomes

[tex]\left(5.91\times \:\:10^{-3}\right)-\left(8.7\times \:\:10^{10}\right)=5.91\times \:\:10^{-3}-8.7\times \:\:10^{10}[/tex]

                                                [tex]=0.00591-87000000000[/tex]

                                                [tex]=-86999999999.9941[/tex]

Hence,

converting -86999999999.9941 in a scientific notation

In order to make our job easier we will remove the sign "-" from number -86999999999.9941 (we will write "-" at the final solution). So after this step we have:

−86999999999.9941  ⟶  86999999999.9941

In order to write number 86999999999.9941 in scientific notation, we need to move the decimal point from its current location (black dot) to the new position such as:

8.6999999999.9941

So, we need to move the decimal point 10 places to the right.

This means that the power of 10 will be positive 10.

Now we have that the

Number part = 8.69999999999941 and

Exponent part = 10

Thus, we conclude that:

−86999999999.9941 = − 8.69999999999941 × 10¹⁰
