Answer:

Its A. Just had this question

Step-by-step explanation:

a=9units

Answer:

solution given:

c=40° exterior corresponding angle

In right angled triangle

<c°+B°+90°=180° [Sum of interior angle of a triangle is 180°

B°=180°-40°-90°=50°

Relationship between base and hypotenuse is given by cos angle

Cos c°=base/hypotenuse

Cos40°=a/12

a=Cos40°×12=9.19or 9 units

Answer:

A. Count by hand.

B. Divide 20 by 2.

Step-by-step explanation:

The midpoint between two points is found by the mean of their coordinates.

Endpoints at (0,0) and (20,0)

So we have x coordinates of 0 and 20. Their mean is:

[tex]\frac{20 - 0}{2} = 10[/tex]

So we can find both counting by hand, or dividing 20 by 2.

Answer:

$23.25

Step-by-step explanation:

Step one:

given data

A store buys a shirt from the vendor for $15

The store makes a 55% profit

Required

The sale price of the shirt

Step two:

Percent profit= sale-cost price/cost price *100

subtitute

55= sale-15/15 *100

0.55= sale-15/15

cross multiply

sale-15= 0.55*15

sale-15=8.25

sale= 8.25+15

sale=$23.25

Answer:

[tex]a_n=50+(n-1)30[/tex]

Step-by-step explanation:

Given series is,

50,80,110....

First term, a = 50

Common difference, d = 80-50 = 30

We need to find the nth term of the given sequence.

The nth term of an AP is given by :

[tex]a_n=a+(n-1)d[/tex]

Put a = 50 and d = 30 in the above formula

[tex]a_n=50+(n-1)30[/tex]

Hence, the nth term of the sequence is [tex]a_n=50+(n-1)30[/tex].

Answer:

x=-2

Step-by-step explanation:

5 times (6 plus x) = 20

6 plus x = 4

x = 4 - 6

x = -2

Answer:

-2

Step-by-step explanation:

Let the number be x

5 × (6 + x) = 20

6 + x = 20/5

6 + x = 4

x = 4 - 6

x = -2

Answer:

The slope would be 1/4.

Step-by-step explanation:

To find the perpendicular slope first you have to set this equation to y

to do this you use the subtraction prop of equality and you will get 12x-9= -3y

then you divide by -3 on both sides to get y by itself

you will get -4x+3=y

now that you know the slope is -4, you must find the negative reciprocal slope of this which means you have to flip the numerator and denominator and make the sign its opposite.

The perpendicular slope would then be 1/4.

Answer:

Rs 1350

Step-by-step explanation:

An average of 5 shirts is Rs 750

The total amount of the 5 shirts is 750×5

= 3,750

The price of 3 shirts is Rs 2400

Therefore the price of the other two shirts can be calculated as follows

= 3750-2400

= 1350

Hence the price of the other two shirts is Rs 1350

Answer:

Anything 3 or more

Step-by-step explanation:

3 x 4 = 12.

12 > 10.

If you follow through with the next multiple of 4, 4, we get 16.

16 > 10.

This is true for any other multiple of 4, making any value 3 or me greater than 10.

Answer:

  a) $8.73

  b) $608.73

Step-by-step explanation:

a) The interest charged is ...

  I = Prt

where P is the amount borrowed, r is the daily rate, and t is the number of days.

  I = $600×0.04848×30 = $8.73 . . . interest

__

b) The amount repaid is the borrowed amount plus interest.

  $600 +8.73 = $608.73 . . . repaid

Answer:

a. The price of an apple is $0.5 and that of a banana is $0.8

b. 4

Step-by-step explanation:

Form simultaneous equations from the information.

For 5 apples and 4 bananas, and the total comes to $ 5.70 this can be;

5 a + 4 b = $5.70----------i

After he puts back 1 apple and 2  bananas, the equation will be;

4 a + 2 b = $3.60 -------------ii

Solve the two equations simultaneously as;

{5 a + 4 b = 5.70 }4 ---------making the a terms equal to eliminate them

{4 a + 2 b = 3.60}5

20 a + 16 b = 22.80 -------subtract the b terms

20 a  + 10b = 18.00

6 b = 4.80

b= 4.80/ 6

b=$ 0.8

Using equation i :

5a + 4b =$5.70

5a + 4*0.8 = 5.70

5a + 3.2 = 5.70

5a = 2.5

a = 2.5 / 5

a=$0.5

The price of an apple is $0.5 and that of a banana is $0.8

b.  

Let the number of apples be ------x

Let the number of bananas be-----x

This is because the target is equal numbers;

Form an equation for total cost as;

0.5 x + 0.8 x = $6

1.3 x = 6

x = 1.3 / 6 = 4.62

Maximum number of bananas to buy = 4

Maximum number of apples to buy = 4

However, he will have $0.8 remaining

x=1

Step-by-step explanation:

Factor out the common term 22.

4x+4(3-2x)=2\times \frac{2(2x+1)}{4}+5

4x+4(3−2x)=2×  

4

2(2x+1)

​   +5

2 Simplify  2\times \frac{2(2x+1)}{4}2×  

4

2(2x+1)

​   to  2x+12x+1.

4x+4(3-2x)=2x+1+5

Simplify  2x+1+5 to  2x+6.

4x+4(3-2x)=2x+6

Expand.

4x+12-8x=2x+6

Simplify  4x+12-8x  to  -4x+12.

-4x+12=2x+6

Add 4x to both sides.

12=2x+6+4x

Simplify  2x+6+4x  to  6x+6.

12=6x+6

Subtract 6 from both sides.

12-6=6x

Simplify 12−6  to  6.

6=6x

Divide both sides by 6

1=x

Switch sides.

x=1

The Expression (x + 2y – 2z) – (2x – 5y – 6z) is equivalent to -x + 3y + 5z

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

(x + 2y – 2z) – (2x – 5y – 6z)

so, (x + 2y – 2z) – 2x + 5y + 6z

= ( x- 2x) + (2y+ y)+ ( 6z- z)

=  -x + 3y + 5z

Hence, (x + 2y – 2z) – (2x – 5y – 6z) is equivalent to -x + 3y + 5z

Given:

The point is located at P(4,7).

It is translated along [tex]\left<1,3\right>[/tex].

To find:

The image of the given point after the translation.

Solution:

The point is translated along [tex]\left<1,3\right>[/tex]. So, the rule of translation is defined by:

[tex](x,y)\to (x+1,y+3)[/tex]

The point is located at P(4,7).

Using the above rule, we get

[tex]P(4,7)\to P'(4+1,7+3)[/tex]

[tex]P(4,7)\to P'(5,10)[/tex]

The image of given point after the translation is (5,10).

Therefore, the correct option is A.
