The value of the expression___ is

The no. of maids who worked at the queen's palace is 58.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, The queen had 300 servants. there were 10 more butlers than cooks. The number of cooks was twice the number of maids.

Assuming the no. of maids to be 'x', therefore no. of cooks is 2x and the no. of butlers is (2x + 10).

∴ x + 2x + (2x + 10) = 300.

5x = 290.

x = 58.

Answer:

Which system of equations has infinitely many solutions? its the last option

To calculate the cost for 115 minutes at the Strike Zone Battling Center, we account for the flat rate for the first 45 minutes and add the additional cost for the remaining 70 minutes at a rate of $0.35 per minute. We find that the total would be $37.25.

The cost calculation for using the cages at the Strike Zone Battling Center operates on a tier system. The first 45 minutes costs a flat rate of $12.75. If a patron uses it for additional time up to 2 hours (or 120 minutes), it's an extra $0.35 per minute. Anything over 2 hours is $0.25 per minute.

To calculate the cost for 115 minutes, we determine that it is less than 2 hours. Therefore, the cost will be the flat rate of $12.75 plus the additional cost for 70 minutes (which is 115 minutes minus the first 45 minutes) at $0.35.

The calculation goes as follows:
$12.75 + (70 * $0.35) = $12.75 + $24.50 = $37.25.

So, for 115 minutes, you would pay $37.25

Answer:

-a^2 + -a + 12

Step-by-step explanation:

Expand the following:

(3 - a) (a + 4)

(3 - a) (a + 4) = (3) (a) + (3) (4) + (-a) (a) + (-a) (4):

-a a + 3 a - 4 a + 3 4

3×4 = 12:

-a a + 3 a - 4 a + 12

-a a = -a^2:

-a^2 + 3 a - 4 a + 12

Grouping like terms, -a^2 + 3 a + 4 (-1) a + 12 = -a^2 + (3 a - 4 a) + 12:

Answer: 264 cm^2

Step-by-step explanation:

22*6.5+22*5.5=22*12=264

The area of the given figure  156.75 sq cm.

Step-by-step explanation:

Here,

The figure is a trapezium.

In this trapezium

a = 22 cm

b = 6.5 cm

A and b are the length of two parallel sides.

Height (h) = 5.5 cm

To find the area of the figure which is consists of two trapezium

Formula

Area of the trapezium = [tex]\frac{1}{2} (a+b)h[/tex]

Now,

The area of one trapezium = [tex]\frac{1}{2} (22+6.5)X5.5[/tex] sq cm

= 78.375 sq cm

So,

The area of the figure = 78.375×2 sq cm = 156.75 sq cm

Step-by-step explanation:

Diameter of circle = 25 m

Therefore, radius of the circle = 12.5 m

[tex]area \: of \: bottom \: of \: pool \\ = \pi {r}^{2} \\ = 3.14 \times ( {12.5)}^{2} \\ = 3.14 \times 156.25 \\ = 490.625 \: {m}^{2} \\ \approx490.63 \: {m}^{2} [/tex]

x coordinate gets multiplied by -1,

y coordinate remains unchanged

a) 6x - 5y = 10x + 7 SOLVING FOR X:

6x-5y=10x+7

−5y=10x+7−6x

−5y=4x+7

−5y−7=4x next divide both sides by four and switch sides

[tex]\frac{-5y-7}{4} =x[/tex]

[tex]x=\frac{-5y-7}{4}[/tex]

a) 6x - 5y = 10x + 7 SOLVING FOR Y:

6x-5y=10x+7

−5y=10x+7−6x then simplify

−5y=4x+7, now divide both sides by negative five

[tex]y=\frac{4x+7}{5}[/tex]

Answer: 65:195

Step-by-step explanation:

The area of the trapezoid is 20 in².

Solution:

Given data:

Length of the bottom base = 7 in

Length of the top base = 3 in

Height of the trapezoid = 4 in

Step 1: Area of the trapezoid formula,

[tex]$A=\frac{b_{1}+b_{2}}{2} \times h[/tex]

Step 2: Substitute the given values in the formula.

[tex]$A=\frac{7+3}{2} \times 4[/tex]

Step 3: Add 7 and 3.

[tex]$A=\frac{10}{2} \times 4[/tex]

Step 4: Divide 10 by 2, we get

[tex]A=5 \times 4[/tex]

Step 5: Multiply 5 by 4, we get

A = 20 in²

The area given in the picture is wrong.

The area of the trapezoid is 20 in².

The surface area of the exhibit is 1,638 cubic inches.

Step-by-step explanation:

Step 1:

If three prisms are out on top of each other we get a shape as follows;

The length of the base [tex]= 9[/tex] inches,

The width of the base [tex]=6[/tex] inches, and

The height of the exhibit [tex]= 3(17) = 51[/tex] inches.

To find the surface area of the total exhibit we consider there to be only one shape which the above dimension.

Step 2:

There are 6 faces to the exhibit.

The surface area of a rectangular prism is given by;

[tex]A=2(w l+h l+h w)[/tex]

By substituting the values, we get

[tex]A=2((6)(9)+(51) (9)+(51) (6)) = 2 (819) = 1,638.[/tex]

The surface area of the exhibit is 1,638 cubic inches.

The red dot on the number line represents the value [tex]\(\frac{4}{5}\)[/tex], corresponding to option C.

In a fraction, the numerator (4) denotes the number of parts considered, while the denominator (5) indicates the total number of equal parts in one whole.

Thus, [tex]\(\frac{4}{5}\)[/tex] signifies four parts out of five, placing the red dot closer to the whole number 1 but not reaching it.

This representation aligns with the fraction's numerical value, emphasizing the position of the red dot on the number line and its fractional significance in relation to the unit interval.

Hence, the correct answer is Option C. 4/5

Determining the value of the red dot requires analyzing its position on the number line relative to specific landmarks and measurements provided; however, without the visual of the number line, a precise answer cannot be given.

The value of the red dot on the number line can be determined based on its position relative to the given reference points. The various descriptions of dots' positions involve a comparison to Car X and Car Y figures, as well as precise measurements in terms of perpendicular hash marks on a graph. To ascertain the value that the red dot represents, we must closely examine its placement on the number line in comparison to these references. However, it's crucial to have a visual representation of the number line to provide an accurate value. The mentioned descriptions such as 'the third dot is about one and two-thirds perpendicular hash marks to the right of the center top perpendicular hash mark' indicate the need to understand measuring units and relative positioning on the number line.

6 bills in the deposit were $10 bills.

Step-by-step explanation:

The total number of bills he gave the teller = 24 bills

x + y = 24 ------------(1)

Let,

x be the number of $5 bills.

y be the number of $10 bills.

The total bank deposit made using $5 and $10 bills are $150.

He deposits $5 bills and $10 bills. So, the equation can be framed as :

5x + 10y = 150 --------(2)

The question is asked for how many $10 bills were in the deposit,

Here 'y' is the number of $10 bills.

To solve for y value :

The eq(1) must be multiplied by 5 and subtract eq(2) from eq(1),

 5x + 5y = 120

-(5x + 10y = 150)

 -5y = -30      

⇒ y = 30/5

⇒ y = 6

Therefore, there were 6 bills in the deposit that are $10 bills.

Answer:

The radius is 2.5 yards

The diameter is 5 yards

Step-by-step explanation:

We want to find the radius and diameter given that, the circumference of the circle is;

C=5π yards.

Recall that, the circumference of a circle is C=πd

This implies that:

[tex]5\pi = \pi \: d[/tex]

Divide both sides by π

[tex]5 = d[/tex]

To find the radius, divide the diameter by 2;

[tex]r = \frac{5}{2} = 2.5[/tex]

The radius is 2.5 yards

The diameter is 5 yards

Answer:

c=3

Step-by-step explanation:

First simplify like terms.

1+4c=7+2c

1+2c=7 (subtract 2c from both sides)

2c=6 (subtract 1 from both sides)

c=3 (divide by 2)

CHECK:

1+4(3)=7+2(3)

1+12=7+6

13=13

Yes!

Answer: [tex]c=3[/tex]

Step-by-step explanation:

Step 1: Simplify both sides of the equation:

[tex]4c+1=2c+7[/tex]

Step 2: Subtract 2c from both sides:

[tex]4c+1-2c=2c+7-2c[/tex]

[tex]2c+1=7[/tex]

Step 3: Subtract 1 from both sides.:

[tex]2c+1-1=7-1[/tex]

[tex]2c=6[/tex]

Step 4: Divide both sides by 2:

[tex]2c/2=6/2[/tex]

Get your answer:

[tex]c=3[/tex]
