Step-by-step explanation:

Tenths

[tex] \frac{1}{10} [/tex]

Whole

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

[tex] 1 = \frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4} [/tex]

∴ There are 4 quarters to make a whole

[tex] 1 = \frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10} [/tex]

sally is taking a test
when she got her score it was 85% of 100% how many questions was on the test and how many did she get wrong

Answers

Answer:

There was 20 questions on the test.

She got 3 wrong.

Step-by-step explanation:

[tex]\frac{85}{100} = \frac{17}{20}[/tex]

20 - 17 = 3

There was 20 questions on the test.

She got 3 wrong.

Answer: There were 20 questions and she missed three.

First of all, you need to simplify 85/100.

85/100 / 5/5 = 17/20.

Now that you know how many questions were on the test, subtract 17 from 20.

20 - 17 = 3

So in conclusion, the test had 20 questions and she missed three.

But this question doesn’t have enough info to be honest, if you multiply 17/20 with any number it’s still going to be 85%.

Find the length of dm in the given fig.​

Answers

Answer:

[tex]DM=12[/tex]

Step-by-step explanation:

(Let the point where the altitude from [tex]D[/tex] intersects [tex]AB[/tex] be called as point [tex]E[/tex].) First, let's find the area of parallelogram [tex]ABCD[/tex]. The area of a parallelogram is simply [tex]b*h=bh[/tex], where [tex]b[/tex] is the parallelogram's base and [tex]h[/tex] is the parallelogram's height. If we let [tex]AB[/tex] and [tex]DE[/tex] be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram [tex]ABCD[/tex] will be [tex]AB*DE=15*8=120[/tex].

Now, how does this information matter, you might ask? Well, we can take either [tex]AB[/tex] or [tex]CB[/tex] to be the base and either [tex]DE[/tex] or [tex]DM[/tex] to be the height. In this case, let's take the latter two options, as we are looking to find the length of [tex]DM[/tex].

Therefore, we know that the area of parallelogram [tex]ABCD[/tex] can also be found by calculating [tex]CB*DM[/tex]. Since we know the values of the area and [tex]CB[/tex], we can write the following equation to solve for [tex]DM[/tex]:

[tex]Area = CB*DM[/tex]

[tex]120=10*DM[/tex] (Substitute [tex]Area=120[/tex] and [tex]CB=10[/tex] into the equation)

[tex]\frac{120}{10}=\frac{10*DM}{10}[/tex] (Divide both sides of the equation by [tex]10[/tex] to get rid of [tex]DM[/tex]'s coefficient)

[tex]12=DM[/tex] (Simplify)

[tex]DM=12[/tex] (Symmetric Property of Equality)

Hope this helps!

Meg is packing a shipping conditier.

There is one section of the shipping container that has not yet been packed. The space available is in the shape of rectangular

prism that measures 2 feet by 3 feet by 33 feet.

She will pack as many boxes into the available space as possible. Each box is in the shape of a cube with side length 1 foot.

The space available in the shinning container and one of the boxes are shown below.

Answers

Answer:

[tex]Boxes= 198[/tex]

Step-by-step explanation:

This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.

We have the following given parameters.

Shipping Container

[tex]Dimension: 2ft\ by\ 3ft\ by\ 33ft[/tex]

The box

[tex]Dimension: 1ft\ by\ 1ft\ by\ 1ft[/tex]

First, we calculate the volume of the shipping container.

[tex]V_A = 2ft * 3ft * 33ft[/tex]

[tex]V_A = 198ft^3[/tex]

Next, we calculate the volume of the box.

[tex]V_B = 1ft * 1ft * 1ft[/tex]

[tex]V_B = 1ft^3[/tex]

The number of box is then calculated as:

[tex]Boxes= \frac{V_A}{V_B}[/tex]

[tex]Boxes= \frac{198ft^3}{1ft^3}[/tex]

[tex]Boxes= \frac{198}{1}[/tex]

[tex]Boxes= 198[/tex]

Hence:

198 boxes will occupy the empty space

Answer:

17° and 73°

Step-by-step explanation:

For two complementary angles, the sum of angles is equal to 90 degrees.

Let other angles = x

First angle = 5+4x ...(1)

ATQ,

5+4x+x=90 ...(2)

Equation (1) and (2) shows the equations for the given problems.

5+5x=90

5x = 85

x = 17°

Other angle = 17

First angle = 5+4x

= 5+4(17)

= 73°

So, the other two angles are 17° and 73° respectively.

Answer:

Contains two 6x6 triangles, contains one 12x3 rectangle, four 2x2 triangles, and two 2x2 squares.

88

Step-by-step explanation:

You only need the area of one side of this shape to find the total area.

((6*6)/2+(3*6)+(2*2)+(2*2))2 = 88. What's inside the parenthesis is the area for one side of the shape, then you can multiply that by two to get the entire area.

Answer:

-2 < x ≤ 6

Step-by-step explanation:

This graph shows conjunction. This means that the two statements of the inequality bare true at the same time. Therefore, it follows that:

x > -2 ("we use greater than" because the empty/unshaded circle indicates that -2 is not included)

And

x ≤ 6 (we use greater than or equal to because the shaded circle indicates 6 is included)

Joining both statements together, we would have:

-2 < x ≤ 6

AE = 3x - 2 and EC = 2x + 3 then DB =

#5

Answers

Answer:

DB = 26

Step-by-step explanation:

Remember:

AE ≅ ECAC ≅ DB

☆The equation in finding the value of x would be 3x - 2 = 2x + 3.

☆Let's solve the equation.

[tex] \: \: \: \: \: \: \: \: \: 3x - 2 = 2x + 3 \\ \frac{ - 2x \: \: \: \ = - 2x}{x - 2 = 3} \\ \frac{ \: \: \: \: \: + 2 = + 2}{x = 5} [/tex]

☆Now that we found the value of x, we are going to plug in for AE and EC.

[tex]AE ; \\ 3x - 2 \\ 3(5) - 2 \\ 15 - 2 \\ 13 \\ \\ \\ \\ and \\ \\ \\ \\ \\ EC; \\ 2x + 3 \\ 2(5) + 3 \\ 10 + 3 \\ 13[/tex]

☆AE and EC each measure 13. To find the length of AC, you will have to add AE and EC. [tex]13 + 13 = 26[/tex]

The length of AC is 26. And since we know that AC is congruent (equal) to DB, meaning they measure the same. DB length is also 26.
