How many triangles are there?

Answer:

about 13 aces

Step-by-step explanation:

.25 x 50= 12.5

25% is equal to .25, you are trying to find 25% of 50. Of means multiple,

so how you get the equation .25 x 50, you can't have half a serve so you round up to 13 aces

Answer:

225 square inches

Step-by-step explanation:

you always multiply when you need to find volume

so you start with the base area multiply it by the height

Base area is 25 square inches

Height is 9in

make it to an equation

25 x 9 = 225 square inches

Answer:

37.7359

Step-by-step explanation:

first you visualize the shape created

if you visualize it... it will look like a right angled triangle

and we are looking for the longest side

remember the pythagoras theorem c^2= a^2 + b^2

in this case we are looking for c

a^2= 20^2

b^2= 32^2

400+ 1024= 1424

therefore c^2= 1424

then you square root 1424

to get 37.7359

Answer:

k = ±12

Step-by-step explanation:

Equation of the graph is,

y = -2x² + kx - 18

Discriminant of a quadratic equation, y = ax² + bx + c is defined by

Discriminant = √(b²- 4ac)

If √(b²- 4ac) = 0,

Equation will have one real solution.

Discriminant of the the given equation = √[k² - 4(-2)(-18)]

Since, graph of the equation is tangent to the x-axis, there will be one real solution.

Therefore, √[k² - 4(-2)(-18)] = 0

k² - 144 = 0

k = ±√144

k = ±12

Answer:

43 minutes

Step-by-step explanation:

Arrival time at grocery store = 11:19 a.m

Time spent in store = 24 minutes

Number of minutes after 11:00 a.m when she arrived and left the store :

Time she left the store :

11:19 a.m + 24 minutes = 11:43 a.m

Minutes after 11:00 when she left :

11:43 - 11:00

= 43 minutes

Answer:

The final bill was $912

Step-by-step explanation:

Since there is 14% tax in order to get the final cost we would need to multiply the cost of the jerseys by 1.14, and so we get...

800 x 1.14 = $912

Answer:

192

Answer:

x + y = 10

6x + 8y = 72

Step-by-step explanation:

Number of packages = 10

Total batteries = 72

For AA:

batteries per package = 6

Let number of packages = x

For AAA:

batteries per package = 8

Let number of packages = y

Number of AA packages + number of AAA packages = 10

Sum of AA + sum of AAA equals 72 batteries

x + y = 10

6x + 8y = 72

Answer:Answer:

x + y = 10

6x + 8y = 72

Step-by-step explanation:

Number of packages = 10

Total batteries = 72

For AA:

batteries per package = 6

Let number of packages = x

For AAA:

batteries per package = 8

Let number of packages = y

Number of AA packages + number of AAA packages = 10

Sum of AA + sum of AAA equals 72 batteries

x + y = 10

6x + 8y = 72

Answer:

54 cents

Step-by-step explanation:

The cost of bookmarks relating to the number of bookmarks is given by the graph shown. Therefore:

From the graph, we can determine the relationship between the cost of bookmarks and the number of bookmarks by using two points. The equation of a line passing through points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\[/tex]

From the graph, y represents the cost of bookmarks in cents and x represent the number of bookmarks. we can see that it passes through the point (2, 30) and (7, 90). Hence:

[tex]y-30=\frac{90-30}{7-2}(x-2)\\\\y-30=12(x-2) \\\\y-30=12x-24\\\\y=12x+6[/tex]

The cost of 4 bookmarks (x = 4):

y = 12(4) + 6

y = 54 cents

Answer:

£7.3

Step-by-step explanation:

2 x £2=£4

3 x £3 = £6

3 x 90 = 270 = £2.7

£4+£6+£2.7= £12.7

20-12.7=7.3

7 pounds and 3

Answer: 4.3

Step-by-step explanation:

2(2)+3(3)+3(.9)=

4+9+2.7=15.7

20-15.7= 4.3

I'm assuming that 100 p is 1 £, if that's not the case this would be wrong

Answer:

k = 0.16

Step-by-step explanation:

First, use distributive property on the left side:

[tex]0.2(k+2.4)=3.2k\\0.2k+0.48=3.2k\\0.48 = 3k\\k = 0.16[/tex]

Answer:

k = 0.16

Step-by-step explanation:

Use distributive property, meaning individually multiply 0.2 to each number/variable within the parameters

0.2 × k = 0.2k

0.2 × 2.4 = 0.48

0.2k + 0.48 = 3.2k

You cannot add a number and a variable so instead we should isolate the variable

Subtract 0.2k from both sides

0.48 = 3.2k - 0.2k

0.48 = 3.0k

0.48 = 3k

Divide both sides by 3

0.16 = k

Answer:

I think the answer is 288

Step-by-step explanation:

I think this because 48/2=24 and 9+3=12 (parentheses means multiply) 24x12=288

Answer:

57% of students

Step-by-step explanation:

14 + 29 = 43%

100% - 43% = 57%

Answer:

For part 1:

-2x^6 + 7x^4 + 3x^3 - 3x^2 + 11x + 20

For part 2:

Based on the foiling of both, they are equal.

Step-by-step explanation:

(-2x^3 +x -5)( x^3 -3x-4)

What we need to do is foil one by one.

I’ve attached a picture of this.

Once you foil, you add like terms.

Now for part 2, x^3 -3x-4 and -2x^3 +x -5, we do the same process.

Question seems incomplete but we would make assumptions in order to answer and explain

Answer and explanation:

If we wish to model this situation in the form of a fraction: there is one container containing 30 cans of fruit juice and 2 people want fruit juice, we would be finding how many fruit juice each person would get from the container.

Given one container= 30 cans of fruit juice

Number of persons that require fruit juice = 2

Therefore fraction of fruit juice in relation to required fruit juice= 30/2

The Length of side AE= 18

Given :

A triangle ABE with the measure of sides .

Explanation :

Find out the measure of AE using similar triangles

From the given figure, Triangle ABE is similar to triangle CDE

When the triangles are similar then the sides are proportional

[tex]\frac{AB}{CD} =\frac{AE}{CE}[/tex]

We know that AB=15, CD=10, CE= 12

Substitute all the values and find out AE

[tex]\frac{AB}{CD} =\frac{AE}{CE}\\\frac{15}{10} =\frac{AE}{12}\\Cross \; multiply \\15(12)= AE(10)\\Divide \; both \; sides \; by \; 10\\\frac{15(12)}{10} =AE\\18=AE\\AE=18[/tex]
