Answer:

30°

Step-by-step explanation:

<4=<2=30

(vertical opposite angles are equal)

Answer:

30 degrees

Step-by-step explanation:

Since 4 is equal on the other side of 2, it would be congruent, which is the same as 2. So, 30 degrees.

Answer:

24 meters

Step-by-step explanation:

The equation for the area of a triangle is A=1/2BxH where B is the base and H is the height. You are given the area and the height so you need to plug those values into the equation and solve.

120=1/2Bx10

240=Bx10

24=B

Answer:

$61.99

Step-by-step explanation:

Based on everything that Taino bought his total amount would be $61.99 . Mental math would mean that no work is shown but for the sake of explanation, I can try to show how to derive the value from the answer choices given quickly. First, we see that the cents in each purchase do not equal a round dollar value when added so the answer must be either A or C. Secondly we add the dollar values and see that it surpasses the round value of 60 making the answer C.

Answer:

A. (2, 5)

Step-by-step explanation:

If B and B' have symmetry, then P is a midpoint between those points. We can determinate the location of point P by using the midpoint equation, whose vectorial form is:

[tex]P(x,y) = \frac{1}{2}\cdot B(x,y)+\frac{1}{2}\cdot B'(x,y)[/tex] (Eq. 1)

If we know that [tex]B(x,y) = (2,8)[/tex] and [tex]B'(x,y) = (2,2)[/tex], then the location of P is:

[tex]P(x,y) = \frac{1}{2}\cdot (2,8)+\frac{1}{2}\cdot (2,2)[/tex]

[tex]P(x,y) = (1, 4)+(1,1)[/tex]

[tex]P(x,y) = (2, 5)[/tex]

Which corresponds to option A.

Answer:

[tex]Length = 18m[/tex]

[tex]Width = 10m[/tex]

Step-by-step explanation:

Given

[tex]Area = 180m^2[/tex]

[tex]Width = Length - 8[/tex]

Required

Determine the Length and the Width

Represent Width with W and Length with L;

So, we have:

[tex]Area = L * W[/tex]

[tex]Area = L * (L - 8)[/tex]

[tex]180 = L * (L - 8)[/tex]

[tex]180 = L^2 - 8L[/tex]

[tex]L^2 - 8L - 180 = 0[/tex]

Expand

[tex]L^2 - 18L + 10L- 180 = 0[/tex]

[tex]L(L - 18) + 10(L- 18) = 0[/tex]

[tex](L + 10)(L- 18) = 0[/tex]

Split

[tex]L + 10 =0[/tex] or [tex]L - 18 = 0[/tex]

[tex]L = -10[/tex] or [tex]L = 18[/tex]

But length cant be negative:

So,

[tex]L = 18[/tex]

Recall that:

[tex]Width = Length - 8[/tex]

[tex]W = 18 - 8[/tex]

[tex]W = 10[/tex]

Hence:

[tex]Length = 18m[/tex]

[tex]Width = 10m[/tex]

The dimension of the rectangular garden is 8m by 10m

The formula for calculating the area of the rectangular garden is expressed as;

A = lw

l is the length

w is the width

If the width of the garden must be 8 meters less than the length, then;

w = l - 8

Substitute into the formula;

180 = l(l-8)

180 =l^2 - 8l

l^2-8l - 180 = 0

Factorize the result;

l(l+10)-8(l+10) = 0

(l-8)(l+10)=0

l = 8 and -10

Since A = lw

w = A/l

w = 180/8

w = 10

Hence the dimension of the rectangular garden is 8m by 10m

Step-by-step explanation:

Answer: $79.50

Step-by-step explanation:

Add together $130 and $125.50 to find out how much she deposited.

$130+125.50=$255.50

Now subtract the amount that was deposited from the total amount in her account.

$335−$255.50=$79.50

Count the number N of data points in your data set.

Sum up all of the data points in your data set (add them all together).

After adding them divided the sum added by the number of numbers

Answer:

16 days

Step-by-step explanation:

Given that:

Number of paramecium Aurelia doubles every 1.25days

5 days ago ; number of paramecium Aurelia = 1

How many are there now?

Using the relation :

Multiplier^(total number of days / time it takes to multiply)

Multiplier = doubles = 2

Total number rof days =. 5

Time it takes to. Multiply = 1.25

The formula becomes :

Number(n) of ptotozoan in 5days is given by 2^(5/1.25)

n = 2^(5/1.25)

n = 2^4

n = 2 * 2 * 2 * 2 =. 16
