Find the area of the triangle.

Find The Area Of The Triangle.

Answers

Answer 1

Answer:

Area of triangle = 1/2*b*h

[tex]\frac{1}{2} * 2.8* 7.8\\\frac{1}{2} * 21.84\\\frac{21.84}{2}\\= 10.92[/tex]

Answer 2

Answer:

10.92 cm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b= 2.8 and h = 7.8 , then

A = [tex]\frac{1}{2}[/tex] × 2.8 × 7.8 = 1.4 × 7.8 = 10.92 cm²

pls help!! A cylindrical vase has a diameter of 12 inches and a height of 12 inches. If the vase is filled 3/4 full of soil, how many cubic inches of soil are in the vase?

Answers

Answer:

Answer: the vase contains 1017.36 inches³ of soil.

Step-by-step explanation:

We would apply thee formula for determining the volume of a cylinder which is expressed as

Volume = πr²h

Where

h represents the height of the cylinder

r represents the radius of the cylinder.

π is a constant whose value is 3.14

From the information given

Diameter = 12 inches

Radius = diameter /2 = 12/2

Radius = 6 inches

Height = 12 inches

Therefore,

Volume of the cylindrical vase =

3.14 × 6² × 12 = 1356.48 inches³

If the vase is filled 3/4 full of soil, then the volume of soil in the vase is

3/4 × 1356.48 = 1017.36 inches³

2r-s=10
rs-s^2=12

Answers

Answer:

s = 6, r = 8 or s = 4, r = 7

Step-by-step explanation:

2r - s = 10

2r = 10 + s

r = 5 + s/2 --(1)

rs - s^2 = 12 --(2)

sub (1) into (2):

(5 + s/2)s - s^2 = 12

5s + 0.5s^2 - s^2 = 12

-0.5s^2 + 5s - 12 = 0

s^2 - 10s + 24 = 0

(s - 6)(s - 4) = 0

therefore s = 6 or s = 4

when s = 6, r = 8 and when s = 4, r = 7

A train covers 165 km in 1.5 hours. How far will the train travel in 2.2 hours if it maintains the same speed?

Answers

Answer:

242

Step-by-step explanation:

165 ÷ 15 = 110

110 × 2.2 = 242

The distance that trains travel in 2.2 hours with the same ratio or same speed will be 242 km.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

A train covers 165 km in 1.5 hours.

The ratio of distance covered to the number of hours is 165/1.5.

Let's say in 2.2-hour train travel x number of km.

The ratio of distance covered to the number of hours x/2.2

Both ratios must be the same,

x/2.2 = 165/1.5

x = 110 x 2.2 = 242 km

Hence "The distance that trains travel in 2.2 hours with the same ratio or same speed will be 242 km".

Hi,

LHS = sinA-cosA+1/sinA+cosA-1

divide both numerator and denominator by cosA

LHS=(tanA−1+secA)/(tanA+1−secA)LHS=(tanA−1+secA)/(tanA+1−secA)

Now

sec2A=1+tan2Asec2A=1+tan2A

sec2A−tan2A=1sec2A−tan2A=1

Using above relation at denominator of LHS

LHS=(tanA−1+secA)/(tanA−secA+sec2A−tan2A)LHS=(tanA−1+secA)/(tanA−secA+sec2A−tan2A)

LHS=(tanA−1+secA)/((secA−tanA)(−1+secA+tanA))LHS=(tanA−1+secA)/((secA−tanA)(−1+secA+tanA))

A student is learning about positive and negative numbers with manipulatives. Each black cube represents + 1 , and each white cube represents − 1 . If there are currently 15 black cubes on the student's desk, how many white cubes must the student add to the desk for the combined value of the cubes to represent 0 ?

Answers

Answer:

15 white cubes

Step-by-step explanation:

Given

[tex]White\ Cubes = -1[/tex]

[tex]Black\ Cubes = +1[/tex]

[tex]Number\ of\ Black\ Cubes = 15[/tex]

Required

Determine the number of white cubes needed to represent 0

To solve this question, we make use of the following equation.

[tex]Black\ Cubes +White\ Cubes = 0[/tex]

If there are 15 black cubes, the the 15 black cubes is worth: +1 * 15

Substitute +1 * 15 for the Black Cubes

[tex]+1 * 15 +White\ Cubes =0[/tex]

[tex]+15 +White\ Cubes =0[/tex]

Collect Like Terms

[tex]White\ Cubes = 0 - 15[/tex]

[tex]White\ Cubes = - 15[/tex]

Recall that 1 white cube is worth -1

So, the number of white cubes is:

[tex]Number = \frac{-15}{-1}[/tex]

[tex]Number = 15[/tex]

Hence, the student needs 15 white cubes

Evaluate 7y - 3y for y=3

Answers

7 . 3 - 3 . 3

= 21 - 9

= 12

Just substitute you y = 3 into the equation

Answer:

The correct answer is 12.

Step-by-step explanation:

To solve this problem, we must plug in 3 for each occurrence of y in the expression because we are given that y = 3.  In this case, we will get the following:

7y - 3y

7(3) - 3(3)

To evaluate, we must simplify this expression.  Due to the order of operations, we should compute the multiplication first.  7*3 = 21 and 3*3=9, so we can plug in these values into our expression.

21 - 9

Now, we can perform the subtraction.

21-9=12

Therefore, the correct answer is 12.

[tex]p(x)=x^3-7x-6 = (x+1)(x+2)(x-3)[/tex]

Step-by-step explanation:

Given that polynomial:

[tex]p(x)=x^3-7x-6[/tex]

Known factor: [tex](x+1)[/tex]

To find:

Equation of the polynomial as the product of linear factors.

Solution:

The degree of polynomial is 3, and when we divide it by a linear equation, the result will be a quadratic.  That quadratic will have 2 solutions.

We can solve the quadratic in two linear factors and as a result we will have the answer.

First of all, we need to divide the polynomial [tex]p(x)[/tex] with the given factor [tex](x+1)[/tex] to find the other factors.

[tex]\dfrac{x^3-7x-6}{x+1} = x^2-x-6[/tex]

Solving the quadratic:

[tex]x^2-x-6 = x^2-3x+2x-6\\\Rightarrow x(x-3)+2(x-3)\\\Rightarrow (x+2)(x-3)[/tex]

So, the answer is:

[tex]p(x)=x^3-7x-6 = (x+1)(x+2)(x-3)[/tex]

Answers

Answer:

a) What is the unit rate for inches per mile on this map?

= 5/4 inches per mile

b) If road B is 8 miles long, how long is road B on the map?

10 inches on the map

Step-by-step explanation:

a) A certain map shows two roads. Road A is 1 1/2 miles long but is 1 7/8 inches long on the map. What is the unit rate for inches per mile on this map​?

Unit rate for inches per mile is calculated as:

1 7/8 inches/ 1 1/2 miles

= 15/8 / 3/2

= 15/8 × 2/3

= 5/4 inches per miles

b) If road B is 8 miles ​long, how long is road B on the map​?

The unit rate is given as:

5/4 inches per miles

Hence,

Road B = 8 miles long

The length of Road B on the map =

5/4 inches per miles × 8 miles

= 10 inches
