3 x 2/5 converted into a mixed number

Answer:

x = 22

Step-by-step explanation:

2x+10+79 = 6x+1

89-1 = 6x-2x

88 = 4x

22 = x

The measure of the unknown value {x} in the given figure is 22.

An angle is formed when two rays have the same end point. The common end point is called vertex.

Given is to find the measure of the unknown value {x}.

The external angle will be equal to the sum of two internal opposite angles. Mathematically, we can write -

6x + 1 = 2x + 10 + 79

6x - 2x = 88

4x = 88

x = 22

Therefore, the measure of the unknown value {x} in the given figure is 22.

Answer:

×=20

Step-by-step explanation:

180-110=70

70+70=140

180-140=40

40÷2=20

Answer:

x = 20°

Step-by-step explanation:

110° and the interior angle of the triangle are a linear pair and sum to 180°

interior angle + 110° = 180° ( subtract 110° from both sides )

interior angle = 70°

the larger triangle is therefore isosceles, 2 base angle are congruent, then

2x = 180° - 140° = 40° ( sum of angles in Δ is 180° )

divide both sides by 2

x = 20°

132/3 = 44

5/8 / 3 = 5/8 x 1/3 =5/24

answer: 4. 44 5/24 watts

Answer:

[tex]\sf 4. \quad 44\frac{5}{24}\:\:watts[/tex]

Step-by-step explanation:

Given information:

To find the number of watts used per hard drive, divide the total amount of watts by 3.

Convert the mixed number into an improper fraction:

[tex]=\sf 132 \frac{5}{8}[/tex]

[tex]\sf =\dfrac{132 \times 8+5}{8}[/tex]

[tex]\sf =\dfrac{1061}{8}[/tex]

Divide by 3:

[tex]=\sf \dfrac{1061}{8} \div 3[/tex]

[tex]\sf =\dfrac{1061}{8} \times \dfrac{1}{3}[/tex]

[tex]\sf =\dfrac{1061 \times 1}{8 \times 3}[/tex]

[tex]\sf =\dfrac{1061}{24}[/tex]

Convert back into a mixed number:

[tex]\sf =\dfrac{1061}{24}[/tex]

[tex]\sf =\dfrac{1056+5}{24}[/tex]

[tex]\sf =\dfrac{1056}{24}+\dfrac{5}{24}[/tex]

[tex]= \sf 44\frac{5}{24}[/tex]

Therefore, the number of watts used per hard drive is [tex]\sf 44\frac{5}{24}[/tex] watts.

The temperature that accurately describes the time that would have spent cooling is 300.

We have the function as f(t) = 349.2(0.98)t

We have to solve for all of the values in the option

When t = 0

This would give us an infinite value for t hence it is not the answer.

When t = 100

we have 61.6

When t = 300

we have f(t) = 7.5

WHen t = 400

f(t) = -6.7

From the solved values the accurate one that has to talk about the time spent cooling is 300 at 7.5

The function f(t) = 349.2(0.98)t models the relationship between t, the time an oven spends cooling and the temperature of the oven. For which temperature will the model most accurately predict the time spent cooling? 0 100 300 400

Answer:

[tex]\textsf{A)}\quad y=-\sqrt{x}+2[/tex]

Step-by-step explanation:

Parent function:

[tex]y = \sqrt{x}[/tex]

The properties of the parent function are:

From inspection of the graph, as the x-values increase, the y-values decrease. Therefore there has been a reflection in the x-axis.

The y-intercept is now at (0, 2), therefore the function has been translated 2 units up.

Translations

For a > 0

[tex]y=-f(x) \implies f(x) \: \textsf{reflected in the} \: x \textsf{-axis}[/tex]

[tex]f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}[/tex]

Therefore:

Reflected in the x-axis:  [tex]-f(x)=-\sqrt{x}[/tex]

Then translated 2 units up:  [tex]-f(x)+2=-\sqrt{x}+2[/tex]

So the equation that represents the transformed function is:

[tex]y=-\sqrt{x}+2[/tex]

Step-by-step explanation:

The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs

15b + 12c = 75

If 1 package of brownies is bought

15b + 12c = 75

15(1) + 12c = 75

15 + 12c = 75

12c = 75 - 15

12c = 60

c = 60/12

c = 5 packs

If 9 packages of brownies are bought

15b + 12c = 75

15(9) + 12c = 75

135 + 12c = 75

12c = 75 - 135

12c = -60

c = -60/12

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal.

Here,  given that;   ΔUVW ≅ ΔXYZ

∠u = ∠x = 70⁰

∠v = ∠y = a⁰

∠w = ∠z = 70⁰

We know that,

Sum of angles of a triangle is 180⁰.

∠x + ∠y + ∠z = 180⁰

70⁰ + a⁰ + 70⁰ = 180⁰

a⁰ + 140⁰ = 180⁰

a⁰ = 180⁰ - 140⁰

a⁰ = 40⁰

Thus, the value ∠y is 40⁰.

Answer:

47.9°

Step-by-step explanation:

complementary angles are two angles that add up to 90° [90 degrees]

so, we can find the complementary angle of 42.1 by finding what angle it needs to add up to 90

we can use subtraction to find this value:

90 - 42.1 = 47.9

So, the complementary angle to the angle 42.1° has a measure of 47.9°

hope this helps, have a lovely day!! :)

You need to know that two angles are complementary when they are equal to 90°. If you want to find the complement of an angle, and you have one of the angle measures, you need to subtract it from 90°. You have an angle measure of 42.1°. This will be the number you subtract.
