Answer:

- $\frac{7}{5}$

Step-by-step explanation: this equation works if you have two points

$\frac{ y_{2-y_{1} } }{x_{2}-x_{1} } =slope$

-3-4/2-(-3)=-7/5

Sean b= 5,79; c= 10,4,el angulo A= 54,46°, el angulo C mide ?

Rzqust [24]

Answer:

$C \approx 91.732^{\circ}$

Step-by-step explanation:

(This exercise is presented in Spanish and for that reason explanation will be held in such language)

El lado restante se determina por la Ley del Coseno:

$a = \sqrt{b^{2}+c^{2}-2\cdot b\cdot c \cdot \cos A}$

$a = \sqrt{5.79^{2}+10.4^{2}-2\cdot (5.79)\cdot (10.4)\cdot \cos 54.46^{\circ}}$

$a \approx 8.466$

Finalmente, el angulo C se halla por medio de la misma ley:

$\cos C = - \frac{c^{2}-a^{2}-b^{2}}{2\cdot a \cdot b}$

$\cos C = -\frac{10.4^{2}-8.466^{2}-5.79^{2}}{2\cdot (8.466)\cdot (5.79)}$

$\cos C = -0.030$

$C \approx 91.732^{\circ}$

Don't go by my answers pls

Illusion [34]

Answer:

19) ( $\frac{-2}{5}$ )^2 = $\frac{4}{25}$

20) - $9^{2}$ = -81

21) $2^{4}$ = 16

Step-by-step explanation:

The only wrong ones are

19) ( $\frac{-2}{5}$ )^2 = $\frac{4}{25}$

20) - $9^{2}$ = -81 ... negative is not inside a parenthesis that's why it is still negative

21) you can add another way is $2^{4}$ = 16

Everything else looks good. Great job!

If an apple pie recipe calls for 3 pounds of candy apples then how many cups of canned apples required

lesya692 [45]

Answer:

Seven cups of canned apples are required to make apple pie recipe

Step-by-step explanation:

The weight of one canned apple is 0.45 pounds

Weight of total canned apple required to make the apple pie recipe is 3 pounds.

Total number of cups of canned apples required

$= \frac{3}{0.45} \\= \frac{300}{45} \\= \frac{20}{3} \\$

So approximately seven cups of canned apples are required to make apple pie recipe

PLEASE HELP OMG the side lengths of triangle MNO are given: MN=5, NO=4, OM=2.5. the triangle is dilated by a scale factor of k w

elena-14-01-66 [18.8K]

The value of the scale factor k, is 1.5

<h3>Perimeter</h3>

The perimeter of a shape is the sum of the side lengths of the shape

<h3>Dimensions </h3>

The dimensions of the triangle MNO are given as:

$MN = 5$

$NO = 4$

$OM = 2.5$

Calculate the perimeter of the triangle as follows:

$MNO=5 + 4 +2.5$

$MNO=11.5$

Divide 17.25 by 11.5 to calculate the scale factor (k)

$k = \frac{17.25}{11.5}$

$k = 1.5$

Hence, the scale factor is 1.5
