Answer:

The other acute angle is 64°

Step-by-step explanation:

Given a right triangle in which the measure of one acute angle is 26°

we have to find the measure of the other acute angle.

Let the required acute angle is x

By angle sum property, the sum of all angles of triangle is 180°

$x^{\circ}+26^{\circ}+90^{\circ}=180^{\circ}$

$x^{\circ}+116^{\circ}=180^{\circ}$

$x^{\circ}=180^{\circ}-116^{\circ}$

$x^{\circ}=64^{\circ}$

Hence, the other acute angle is 64°

Ming wants to make a 40% sugar solution. She had already poured 3 L of a 80% sugar solution into a beaker. How many L of a 10% s

jeyben [28]

Answer:

Ming must add 0.375 L of a 10% sugar solution

Step-by-step explanation:

if 3 L = 80%

1.5 L should = 40% (since it is half of 80%)

and if 40 divided by 4 = 10%

1.5 also needs to be divided by 4

so 1.5 divided by 4 = 0.375

that means Ming must add 0.375 L of a 10% sugar solution

I need help I don’t know how to do this

IgorLugansk [536]

Answer:

PL and LM

Step-by-step explanation:

The definition of perpendicular is two lines that create a 90 degree angle. There are a lot of those in a rectangular prism. One of them is PL and LM, because they intersect to create a right angle.

$4(k+5)=2(9k-4)\qquad|\text{use distributive property}\\\\(4)(k)+(4)(5)=(2)(9k)+(2)(-4)\\\\4k+20=18k-8\qquad|\text{subtract 20 from both sides}\\\\4k=18k-28\qquad|\text{subtract 18k from both sides}\\\\-14k=-28\qquad|\text{divide both sides by -14}\\\\\boxed{k=2}\to\boxed{d.}$

A transformation T : (x, y) → (x + 3, y + 1). Find the preimage of the point (4, 3) under the given transformation. (7, 4) (1, 2

motikmotik

Answer:

(1, 2)

Step-by-step explanation:

Remember that the final shape and position of a figure after a transformation is called the image, and the original shape and position of the figure is the pre-image.

In our case, our figure is just a point. We know that after the transformation T : (x, y) → (x + 3, y + 1), our image has coordinates (4, 3).

The transformation rule T : (x, y) → (x + 3, y + 1) means that we add 3 to the x-coordinate and add 1 to the y-coordinate of our pre-image. Now to find the pre-image of our point, we just need to reverse those operations; in other words, we will subtract 3 from the x-coordinate and subtract 1 from the y-coordinate.

So, our rule to find the pre-image of the point (4, 3) is:

T : (x, y) → (x - 3, y - 1)

We know that the x-coordinate of our image is 4 and its y-coordinate is 3.

Replacing values:

(4 - 3, 3 - 1)

(1, 2)

We can conclude that our pre-image is the point (1, 2).

Find the surface area.

denpristay [2]

Step-by-step explanation:

a rectangular prism (like this brick) has the same basic structure as a cube (like a die) : it has 6 sides.

while a die has 6 equal sides, a rectangular prism has 3 pairs of equal sides :

top and bottom

left and right

front and back

all we have to do is calculate the areas of the 6 rectangles and add them up. that's it.

your remember, the area of a rectangle is

length × width

in our case we have

top and bottom : 2.5×11.5 × 2 = 28.75×2 = 57.5 in²

left and right : 2.5×5 × 2 = 12.5×2 = 25 in²

front and back : 11.5×5 × 2 = 57.5×2 = 115 in²

so, the total surface area of the whole block is

57.5 + 25 + 115 = 197.5 in²
