Answer:

A. secant

Step-by-step explanation:

For trigonometric ratios, we know that cosine is $\frac{adjacent}{hypotenuse}$ . The reciprocal of something is just flipped over. So the reciprocal of cosine is $\frac{hypotenuse}{adjacent}$ , which is the ratio for secant.

Another way we can remember this is $sec x = \frac{1}{cos x} \\\\cos x = \frac{1}{sec x}$

Three girls cut out decimal models of hundredths. Amber doesn't shade any of her models. Grace qualifies three fifths of a model

Varvara68 [4.7K]

Answer:

$Amber = 0$

$Grace = 0.60$

$Marsha =1.70$

Step-by-step explanation:

Given

<em>Decimal Grid = Hundredths</em>

$Amber = None$

$Grace = \frac{3}{5}th$

$Marsha = 1 + \frac{7}{10}th$

To solve for each:

We have:

For Amber:

$Amber = 0 * 100$

$Amber = 0$

For Grace:

$Grace = \frac{3}{5}th$

$Grace = \frac{3}{5} * 100$

$Grace = \frac{300}{5}$

$Grace = 60$

This means that Grace shaded 60 of the hundredth models.

Decimal shaded is:

$Grace = 60 * \frac{1}{100}$

$Grace =\frac{60}{100}$

$Grace = 0.60$

For Marsha:

$Marsha = 1 + \frac{7}{10}th$

$Marsha = \frac{10 + 7}{10}th$

$Marsha = \frac{17}{10}th$

$Marsha = 1.7th$

Multiply this by 100, to get the number of shaded

$Marsha = 1.7 * 100$

$Marsha = 170$

This means that Marsha shaded 170 of the hundredth models.

Decimal shaded is:

$Marsha = \frac{170}{100}$

$Marsha =1.70$

Answer:

Step-by-step explanation:

Use the formula

$A(t)=P(1+\frac{r}{n})^{nt}$

Fill in the info we are given:

$1210=P(1+\frac{.038}{12})^{(12)(6)}$ and

$1210=P(1.003166667)^{72}$ and

1210 = P(1.255632915) so

P = $964

What value can be written on the blank line to make the expressions equivalent

Gala2k [10]

<span>The expression is missing from the question, but here is the given expression which I got from a similar question.

48 + 54 = ___ ´ (8 + 9)

Theleft-hand side of the equation is:
48 + 54 = 102
Now the right-hand side of the equation:
A </span>× (8+9) = Right-hand side
A × (8+9) = 102
Solving for the unknown variable A,
A × 17 = 102
Dividing by 17 on both sides,
A × 17 ÷ 17 = 102 ÷ 17
A × 1 = 6
A = 6

Hence,
48 + 54 = 6 x (8 + 9)
