My sister needs help! She’s in 3rd grade

Answer:

5(5+6)

Step-by-step explanation:

25+30

Lets factor each expression

25 = 5*5

30 = 5*6

We can factor out a 5

5(5+6)

Answer:

16%

Step-by-step explanation:

The mean is $15 and the standar deviation is $3.

mean = 15  and SD = 3

We need to find percentage less than 12 per hour

P(x<12)= P(x=12)

to find P(x=12) we find z-score

[tex]z= \frac{x-mean}{SD} =\frac{12-15}{3} =-1[/tex]

Now use z-score table . z-score = 0.1587

P(x=12)=0.1587

To get percentage we multiply by 100

0.1587 * 100 = 15.87 = 16%

Answer:

x = 57.22754579  

Step-by-step explanation:

We know cos 63 = adjacent/ hypotenuse

                  cos 63 =  15 sqrt(3)/x

Multiply each side by x

x cos 63 =15 sqrt( 3 )

Divide each side by cos 63

x cos (63)/ cos (63) = 15 sqrt(3)/cos (63)

  x = 15 sqrt(3)/ cos 63

x = 57.22754579  

Answer:

66°

Step-by-step explanation:

the base angles of an isosceles triangle are equal

the sum of the 3 angles in a triangle = 180°

subtract the vertex angle from 180 and divide the result by 2

base angles = 180° - 48° = 132°

base angle = [tex]\frac{132}{2}[/tex] = 66°

Answer:

Step-by-step explanation:

If the lines are parallel, then angles 1, 7, 3, and 5 are congruent because they are vertical/corresponding angles.

Therefore, they are all 113 degrees. For the rest of them, you just subtract from 180 to get 67. Therefore,

2 = 67 degrees

3 = 113 degrees

4 = 67 degrees

5 = 113 degrees

6 = 67 degrees

7 = 113 degrees

8 = 67 degrees

Answer:

C. 2 1/8 ounces

Step-by-step explanation:

The kitten gained 2 1/8 ounces, and you can prove it through the following reasoning.

Kitten at birth was 3 3/8 ounces

Gained Weight (WG) was (unknown)

The kitten was 5 1/2 after being sold.

5 1/2 - 3 3/8 = GW (please note that 1/2 is also 4/8, therefore the equation can be represented by 5 4/8 - 3 3/8 = GW

2 1/8 = GW

Answer: The kitten gained 2 1/8 ounces

Step-by-step explanation:

We have to find the difference between the weights of kitten.

5 1/2 - 3 3/8 = weight gained

We solve the compound fraction like this.

5 1/2

2*5+1 = 11

This goes to 11/2

While

3 3/8

8*3+3 = 27

This goes to 27/8

So we subtract 11/2 - 27/8

44 - 27/8

17 / 8

This comes to 2 1/8 ounces.

Answer:39/4

Step-by-step explanation: What I'd do first is set the question up as an ordered pair, for example (x,y) have the uniforms be represented by x and the cost be represented by y. We know that the cost of five uniforms is $66, so we can substitute (x,y) into (5,66). We can then do the same for nine uniforms which is 105 (9,105). The equation we are going to use to find the slope is y2-y1/x2-x1 = 105-66/9-5.

This should result in 39/4. Make sure to always simplify when needed, in this case we don't have to.

Hope this helped.

You just add the amount she spent and the amount she had left over to find out how much she had before she went into the game store. So 9.72+34.79 is $44.51. Hopefully this helped her out.

Answer:

25.22

Step-by-step explanation:

7.76/4 and then after the unit rate you multipy it by 13

Answer:

13 glue sticks cost $25.22

Step-by-step explanation:

We can use ratio's to solve this problem.  We put price over number of sticks.

$7.76            x dollars

------------- = ---------------

4 sticks          13 sticks

Using cross products

7.76 * 13 = 4 * x

100.88 =4x

Divide each side by 4

100.88 /4 = 4x/4

$25.22 =x

Answer:

Last choice

Step-by-step explanation:

Let's assume m is the "y" (dependent variable) and d is the "x" (independent variable) because the number of minutes is larger, and that would make more sense.

5760/4=1440

10080/7=1440

...

Slope is 1440, and it is direct variation

m=1440d

It COULD also be the third choice, but mathematical convention would have us put the coefficient first.

Answer:

$67.20

Step-by-step explanation:

We need to find out how much 1% costs so we can multiply that cost by 12 because it goes up 12%.

60/100=0.6

0.6*12=7.2

Now that we have the markup amount we add it to the actual price of $60 so

60+7.2=$60.20

Answer:

2√5 + 9√7

Step-by-step explanation:

The given expression is

2√20 - 3√7 - 2√5 + 4√63

√20 = √4√5 = 2√5

√63 = √9√7= 3 √7

Now replace the above value with the given expression

2*2√5 - 3√7 -2√5+4*3√7

= 4√5 - 3√7-2√5+12√7

= 4√5 -2√5 - 3√7 +12√7

Simplifying the like terms, we get

= 2√5 + 9√7

Thank you.

The expression 2 sqrt(20) - 3 sqrt(7) - 2 sqrt(5) + 4 sqrt(63) simplifies to 2 sqrt(5) + 9 sqrt(7) after breaking down and combining like radicals.

We start by simplifying each radical. Notice that sqrt(20) can be written as sqrt(4*5), which simplifies to 2sqrt(5). Similarly, sqrt(63) can be written as sqrt(9*7), which simplifies to 3sqrt(7). Therefore, our expression becomes:
2(2sqrt(5)) - 3sqrt(7) - 2sqrt(5) + 4(3sqrt(7)) = 4sqrt(5) - 2sqrt(5) - 3sqrt(7) + 12sqrt(7) = 2sqrt(5) + 9sqrt(7). This gives us the simplified form of the original expression.

Step-by-step explanation:

Answer:

f(1) = -3

f(8) =3

f^-1 (5) =2

f^-1 (2) =4

Step-by-step explanation:

f(1) = is the value when x=1  which is -3

f(8) = is the value when x=8 which is 3

f^-1(5) is x value when   y=5  so find y=5 in the table and read the x value  x=2

f^-1 (2) is the x value when y=2 so find y=2 in the table and read the x value  x=4

Answer:

f(x) = 2/3x +4

Step-by-step explanation:

The initial value is another name for the y intercept, so b = 4

Rate of change is another name for slope so m = 2/3

We can use the equation y =mx+b

y = 2/3 x + 4

We want it in function form

f(x) = 2/3x +4

The coefficients and constants of the equations are proportional to each other because the graphs of the two equations overlap each other.

The correct option is C.

When Henry multiplied the first equation by -3 and added the two equations together, resulting in the equation 0 = 0, it indicated that the two original equations were dependent and represented the same line. This means that the system of equations has infinitely many solutions. Each point on the line represented by the equations satisfies both equations simultaneously.

When Henry graphed the equations on his graphing calculator and saw only one line, it further confirmed that the two equations are identical or overlapping. The lack of a visible second line indicates that the graphs coincide with each other, overlapping perfectly. This occurs because the coefficients and constants of the equations are proportional to each other, resulting in the same line when graphed.

Hence, option C is the correct choice, as the overlapping of the graphs confirms that the system of equations has infinitely many solutions.

Answer:

.70p  

p(1-.30)

Step-by-step explanation:

Tony plans to purchase a jacket that costs p dollars. In a week the jacket will go on sale for 30% off.

Tony writes althea following expression

p - .30p

Here P  or 1P  are same

So expression becomes 1p - 0.30p

Both are like terms

so we can subtract it

1p - 0.30p = 0.70p

Also we can write 1p - 0.30p  as  p(1-0.30)

We can take out p that is in common

Equivalent expression is .70p  and p(1-.30)

Answer:

x=7

Step-by-step explanation:

The two triangles are similar .

We can use the ratio's of the side to figure out x

2                3.5

-------- = --------------

4               x

Using cross products

2x = 4*3.5

2x=14

Divide each side by 2.

2x/2 = 14/2

x=7

the length of x = 7.

To solve for x using the given ratios of the sides of the two similar triangles, we can follow these steps:

Set up the proportion using the given ratios:

[tex]\[ \frac{2}{4} = \frac{3.5}{x} \][/tex]

Cross multiply:

[tex]\[ 2x = 4 \times 3.5 \][/tex]

Perform the multiplication on the right side:

2x = 14

To solve for x, divide both sides of the equation by 2:

[tex]\[ \frac{2x}{2} = \frac{14}{2} \][/tex]

Simplify both sides:

[tex]\[ x = \frac{14}{2} \][/tex]

Calculate the value:

x = 7

So, x = 7.

Find the length of x.

The actual measurements are 12 feet by 24 feet.

The ratio between a distance on a map and its corresponding distance on the ground is referred to as the "map scale."

The scale of a map is the proportion between the distance shown on paper and the actual distance on the ground.

Given:

1 inch = 16 feet.

Dimension of bedroom on blue print is 0.75 inches x 1.5 inches.

so, the actual dimension of bedroom is

= 0.75 x 16 by 1.5 x 16

= 12 feet by 24 feet.
