Which algebraic expression represents the situation "add seven to the product of a number and ten"?

Answer:

106 students

Step-by-step explanation:

If you take the 2 3/5 and covert it into a whole number by: 2×3+5 = 10

and then you have 96 girls so you add the whole number you got that is 10 and the 96 girls

=96+10= 106 students

Answer:

0.525 is the number.

X = Y/P%

X = 0.84/160%

p = 160%/100 = 1.6

X = 0.84/1.6

X = 0.525

Answer:

Step-by-step explanation:

Let h be the height of the door

and w be its width

The statement “The height of the door is I foot more than twice its width”

can be translated mathematically like this :  h = 2w + 1

Let’s solve the equation for w:

h = 2w + 1

⇔ 2w = h - 1

[tex]\Leftrightarrow w=\frac{h-1}{2}[/tex]

now , if the door is 7 feet high then it’s width is equal to :

[tex]\Rightarrow \frac{7-1}{2} =\frac{6}{2} =3 \ ft[/tex]

Answer:

3 feet

Step-by-step explanation:

It mentions that the height of the door is 1 foot more than twice its width.

The width of a door of height 7 feet will be :

Step-by-step explanation:

Use the zero's trick for 10's.

The product of the given multiplications are 300000, 30000, 3000 and 300

Multiplication is when you take one number and add it together a number of times.

Example: 5 multiplied by 4 = 5 + 5 + 5 + 5 = 20. We took the number 5 and added it together 4 times. This is why multiplication is sometimes called "times".

Given that are four multiplication, 10000x30, 1000x30, 100x30 and 10x 30,

We know,

Multiplication by multiples of 10, 100, 1000, 10000:

We multiply the multiplicand by the non-zero digit of the multiplier. Then we add the same number of zero to the extreme right of the product as the multiplier has.

For example :-

26 × 10000 = 260000

524 × 10000 = 5240000

Therefore,

10000 x 30 = 300000

1000 x 30 = 30000

100 x 30 = 3000

10 x 30 = 300

Hence, the product of the given multiplications are 300000, 30000, 3000 and 300

Answer:

To find the surface area of a rectangular prism, measure the length, width, and height of the prism. Find the area of the top and bottom faces by multiplying the length and width of the prism. Then, calculate the area of the left and right faces by multiplying the width and height.

x^2 = (16)^2 + (16)^2

x^2 = 256 + 256

x^2 = 512

x = 16√2

Step-by-step explanation:

(x - h)² + (y - k)² = r²

with (h, k) being the center and r the radius.

in our case the center is (1, 3), the radius is 3.

so, the right answer is the third answer option

(x - 1)² + (y - 3)² = 9

The missing dimension of the base is 3 meters

The given parameters are:

Let the missing dimension of the base be w.

So, we have:

V = lwh/3

This gives

22 = 2 * w * 11/3

Multiply both sides by 3

66 = 2 * w * 11

Divide both sides by 22

w = 3

Hence, the missing dimension of the base is 3 meters

Step-by-step explanation:

The sides and angles of the right triangle area as follows:

m∠C = 28°

m∠A = 62°

AC = 17 units

Using trigonometric ratios,

cos C = 15 / 17

m∠C = cos⁻¹ 0.88235294117

m∠C = 28.0726015272

m∠C = 28°

m∠A = 180 - 28 - 90 = 62°

AC = 17 units

AC is the hypotenuse of the right angle triangle.

Answer:

12/5 hours

Step-by-step explanation:

Let the total area to be painted be X

Let S be the rate at which Sally paints and J be the rate at which Joe paints

We have:
X/S = 4 hours (1)

X/J = 6 hours (2)

(1) ÷ (2) ==>
LHS = X/S ÷ X/j = X/S × J/X ==> J/S (3)
RHS = 4/6 = 2/3 (4)

From (3) and (4)
J/S = 2/3 or J =2/3 × S

If they both paint at the same time time taken is

X/(S+J)
S + J = S + 2/3 *S = 5/3S
So time taken for both of them to paint is X/(5/3)*S = X/S * 3/5
But we know from (1) that X/S = 4 so time taken = 4 * 3/5 = 12/5 hours

The values of n does either player have a winning strategy is; Player B has a winning strategy for all n ≥ 2.

Let us use an example to solve this question. The game is played on the complete graph Kₙ (n ≥ 2), which consists of n vertices, each pair of vertices joined by an edge.

Now, Initially all edges are unpainted. At each turn, A chooses an edge, which B paints blue or red. Now, B will win if, after the last edge is painted, there is a vertex which is joined to all other vertices by blue edges. If that doesn't happen, then A wins.

The winning strategy of B is described by 3 rules which are;

Thus, if n >2, the first edge will always be painted red, the second will always be painted blue.

In conclusion, when we apply that same scenario to our question it is the same result and as such Player B has a winning strategy for all n ≥ 2.

A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables.

In other words, it reflects how similar the measurements of two or more variables are across a dataset.

When one variable changes, the other variables change in the same direction or opposite direction.

Perfect positive correlation :When one variable changes, the other variables change in the same direction.

Perfect negative correlation :When one variable changes, the other variables change in the opposite direction.
