Answer:

x = 12

y = 12

Step-by-step explanation:

Each triangle is a right angle triangle

5² + x² = 13²

x² = 169 - 25

x = √144

x = 12

The shape is a parallelogram

Therefore

x = y

y = 12

A recipe from Sally’s "Chocoholic’s Cookbook" requires 70\frac{1}{6} grams of chocolate for each chocolate fudge cake. How many

erik [133]

Answer:

842 grams

Step-by-step explanation:

$70\frac{1}{6} =\frac{421}{6}$

$\frac{421}{6} *12\\\\842$

One cake consists of 421/6 grams of chocolate.

Since Sally wants to give 1 cake to 12 friends, we multiply 421/6 and 12.

To make 12 cakes, she needs 842 grams of chocolate.

Can someone show me how to do it and the answer

Virty [35]

Answer:

B

Step-by-step explanation:

The equation of a circle is

(x-h)^2 + (y-k)^2 = r^2

h= 9, k = -7

r = 2, so r^2 = 4.

We now know that the equation must equal 4, so we can rule out answers A and C.

Plug in the values for h and k to get

(x-9)^2 + (y+7)^2 = 4

Choice B is correct!

75 is 128% of what number

Oksana_A [137]

$\bold \pink{let \: the \: number \: be \: x}$

$\mathsf{128\% \times x = 75}$

$\\ \\ \frac{128}{100} \times x = 75 \\ \\ x = \frac{75}{1} \times \frac{100}{128} \\ \\ x = \frac{7500}{128}$

$\boxed{x = 58.59375}$

75 is 128% of 58.59375

Answer:

Vertical angles

Step-by-step explanation:

The diagram shows two straight line intersecting to form vertical angles. One of such pair of vertical angles formed is <1 and <2.

Vertical angles are congruent to each other. Therefore, the reason why <1 ≅ <2 is because they are vertical angles or vertical angles pair.
