Answer:

-25.5

Step-by-step explanation:

Hi Baby girl,

59.2 - 84.7 can be worked out this way:

First calculate 84.7 - 59.2 on your rough paper

That gives 25.5

Finally make your answer a negative number (since the question is about subtracting a larger number from a smaller number)

The answer therefore is -25.5

Answer:

Step-by-step explanation:

since you are learning about similar triangles... i'd guess that some where of the picture.. there is some words that say, that the two smaller triangles are the same, similar , congruent.. so that we can just add up angles 1 + 2 or

13 + 13 = 26 °

sertanlavr [38]

Answer:

Step-by-step explanation:

We want to evaluate the fraction below for x = 3. We will put the value of x to be 3:

$\dfrac{7^2}{x^2-2}\\\\= \dfrac{7^2}{3^2-2}\\\\= \dfrac{49}{9-2}\\\\= \dfrac{49}{7} = 7$

The equation y=2(x-1)^2-5y=2(x−1)

marin [14]

Answer:

(b) It is symmetrical about $x = 1$

Step-by-step explanation:

Given

$y = 2(x - 1)^2 - 5$

See attachment for options

Required

True statement about the graph

First, we check the line of symmetric

$y = 2(x - 1)^2 - 5$

Expand

$y = 2(x^2 - 2x + 1) - 5$

Open bracket

$y = 2x^2 - 4x + 2 - 5$

$y = 2x^2 - 4x -3$

A quadratic equation $y = ax^2 + bx + c$ has the following line of symmetry

$x = -\frac{b}{2a}$

By comparison, the equation becomes:

$x = -\frac{-4}{2*2}$

$x = \frac{4}{4}$

$x = 1$

Hence, the line of symmetry is at: $x = 1$

(b) is true.

Chase use 1/6 cup of bananas for every 2/3 cup of apples to make a smoothie. Enter the number of cups of bananas Vhase uses for

Reika [66]

Answer:

1/4 cup of bananas

Step-by-step explanation:

1/6 cup of bananas = 2/3 cup of apples

1/6 cup of bananas = 4/6 cup of apples

1/24 (1/6 ÷ 4 since 4/6 cup of apples is 4 units and we need 1 unit) cup of bananas = 1/6 cup of apples

1 cup of apples = 1/4 (1/24 x 6 for 6 units) cup of bananas
