lara31 [8.8K]

a) Net result of Tamiko's transactions = $143.75

b) Total amount she can save = $86.25

Step-by-step explanation:

Step 1 :

Given,

Amount Tamiko got in her first check =  $109.60

Amount of the bonus check = $34.15

Fraction of the amount she wants to save = \frac{3}{5}

We need to find the net results of her transactions and the amount she will save

Step 2 :

The new result of her transactions can be computed by adding the amount she has received through both the check.

Total amount she received  = 109.60 + 34.15 = 143.75

Total amount she can save =   \frac{3}{5} × 143.75 = 86.25

Step 3 :

Answer :

a) Net result of Tamiko's transactions = $143.75

b) Total amount she can save = $86.25

The length of a rectangle is 3 inches more that its width. The perimeter of the rectangle is at least 30 inches. Which inequalit
Nutka1998 [239]
<span>Perimeter of a rectangle: 2(l + w)
</span>
2(l + w) ≥ 30 in
<span>

Simplify- divide both sides by 2.

l + w ≥ 15 in


Substitute (w + 3) into l so only 1 variable is used.

(w + 3) + w ≥ 15 in


Simplify further- add variables and subtract 3 from both sides.

2w ≥ 12 in


Divide both sides by 2.

w ≥ 6 in

assume that 2000 births are randomly selected and 64 of the births are girls. use subjective judgment to describe the number of
tatuchka [14]

Total no. of births = 2000

Births of girls = 64

Birth% of girls

=  \frac{64}{2000}  \times 100

=  \frac{64}{20}

=  \frac{6.4}{2}

= 3.2\%

Hence, the number of girls are significantly low.

Are the triangles similar? If so, state the similarity and the postulate or theorem that justifies your answer.
malfutka [58]

The triangles are similar by SAS principle.

<h3>How to know similar triangles?</h3>

Similar triangles have the same shape but may have different sizes.

In similar triangles, corresponding sides are always in the same ratio.

The corresponding angles are congruent.

Therefore, using SAS ratio,

6 / 8 = 8 × 3 / 32

6 / 8  = 24 / 32 = 3 / 4

Therefore, the corresponding sides are a ratio of each other.

Therefore, the triangles are similar by SAS principles because the two triangles have two pairs of sides in the same ratio and the included angles are also equal
