hope it helps u

If at 9 a.m. the temperature was below freezing, which means below 0 degrees Celsius, then the point would be plotted in the third quadrant (III).

The coordinate plane has four quadrants, which are numbered using Roman numerals I, II, III, and IV, and they are separated by the x-axis and y-axis.

In this case, the temperature was below freezing at 9 a.m., which means it was less than 0 degrees Celsius.

The point would be plotted in the third quadrant (III), where the x-value is negative and the y-value is negative, because the x-axis represents the time in hours before noon and the temperature is negative.

At 11 a.m., however, the temperature was 10 degrees Celsius, which is a positive value.

Thus, the point would be plotted in the first quadrant (I), where both the x-value and the y-value are positive, because the x-axis represents the time in hours before noon and the temperature is positive.

I would first find the volume of the hole and multiply that by 2 because there's 2 holes.

[tex]v = lwh[/tex]

[tex]v = (5)(8)(5)[/tex]

[tex]v = 200[/tex]

[tex]200 \times 2 = 400[/tex]

//

I would then find the volume of the entire cinder block.

[tex]v = lwh[/tex]

[tex]v = (16)(8)(8)[/tex]

[tex]v = 1024[/tex]

//

I would then substract.

[tex]1024 - 400 = 624[/tex]

The volume of the cinder blocks is 624 inches³

Answer:

₹2520

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 12600 × 0.1 × 2 = 2520

I = ₹ 2,520.00

The simple interest accumulated

on a principal of ₹ 12,600.00

at a rate of 10% per year

for 2 years is ₹ 2,520.00.

Answer:

3 * (x + 7)

Step-by-step explanation:

Mark number as x

Then the sum of a number and seven is x + 7

Three times x + 7 can be written as

3 * (x + 7)

Parentheses mean that we first add x and 7 and then multiply their sum by 3

Alternatively you can write it as 3x + 21, since

3 * (x + 7) = 3 * x + 3 * 7 = 3x + 21

Answer:

x-3.5

Step-by-step explanation:

I suppose that x= the orginal cost of the pairs of shoes.

The expression that shows the final price of a pair of shoes is given by f(x) = (x - 3.5).

Given is that the mall is having a sale on all shoes. Each pair is $3.50 off the original price.

Assume the original price of the shoes is $x. So,  the expression that shows the final price of a pair of shoes is given by -

f(x) = (x - 3.5)

Therefore, the expression that shows the final price of a pair of shoes is given by f(x) = (x - 3.5).

Step-by-step explanation:

A snow cone machine price at $139 is on after for 20 off.

The price after discount=139-20=$199

The sale tax rate 6.75%

Price with sales tax=199+(6.75%×199)

=199+(0.0675×199)

= 199+8.03

=$127.03

The equation that can be used to represent the turbo jet pack will be 6b + 7.

From the information given, the turbo jet pack is given as six times the number of boxes plus seven. This will be:

= (6 × b) + 7

= 6b + 7

The x-ray vision glass is given as five fewer than two times the number of boxes. This will be:

= (2 × b) - 5

= 2b - 5

The invisible shield is given as one more than ten times the number of boxes. This will be:

= (10 × b) + 1

= 10b + 1

Total Pens, owned by all students between all of them = 360

Total children = 360
Students having one pen = 95% of 360 = 18

Remaining 95% = 360 - 18 = 342

Half of remaining ie 342 = 171, have two pens

Other half of remaining ie 171 have no pens

Total pens, all children have between all of them = Summation (number of students x number of pens)

= (18 x 1) + (171 x 2) + (171 x 0)

= 18 + 342

= 360

(x-11)(7x-2)=0

x=11 or x=2/7

Answer:

x = [tex]\frac{2}{7}[/tex], x = 11

Step-by-step explanation:

Given

7x(x - 11) - 2(x - 11) = 0 ← factor out (x - 11) from each term

(x - 11)(7x - 2) = 0

Equate each factor to zero and solve for x

x - 11 = 0 ⇒ x = 11

7x - 2 = 0 ⇒ 7x = 2 ⇒ x = [tex]\frac{2}{7}[/tex]

Answer: 61.16 ft

Step-by-step explanation:

We can think in this situation as a triangle rectangle.

where:

The height of the tree is one cathetus

The shadow of the tree is the other cathetus.

We know that the angle of elevation of the sun is 78°, an angle of elevation is measured from the ground, then the adjacent cathetus to this angle is the shadow of the tree. And the opposite cathetus will be the height of the tree.

Now we can remember the relationship:

Tg(A) = (opposite cathetus)/(adjacent cathetus)

Where:

A = 78°

Adjacent cathetus = 13ft

opposite cathetus = height of the tree = H

Then we have the equation:

Tg(78°) = H/13ft

Tg(78°)*13ft = H = 61.16 ft
