Answer:

The answer is that Bert scored 60, while Jose scored 30.

Step-by-step explanation:

First, we make an equation. We will use 2x+x=90, where x equals Jose's score, and 2x equals Bert's. Next, we combine like terms, and thus get 3x=90. Now, we divide by three on both sides to get what x equals. This gives us 30. To answer the question, you now plug in x for each part of the equation. 2(30)+30+90. This gives us 60+30=90, which gives 90=90, which is true. So, looking at the eqation, we can see our answer. Bert scored 60, which is twice what Jose scored since Jose only scored 30.

C is the center of the circle. Find the area of the segment shown in the figure,

Semmy [17]

Answer: A 28.50 sq. u

Step-by-step explanation:

In the given figure , radius of the circle : r= 10 u

Central angle made by Arc ED: $\theta$ = 90° ( right angle )

Now , the area of the segment is given by :-

Area of segment = Area of sector (ECD) - Area of triangle(ECD) (i)

Formula : Area of right triangle = 0.5 x Base x Height

Area of sector = $\dfrac{\theta}{360^{\circ}}\times\pi r^2$

Using above formulas in (i) and substituting corresponding values , we get

Area of segment =

$\dfrac{90^{\circ}}{360^{\circ}}\times\pi (10)^2-0.5\times10\times10\\\\=\frac{1}{4}(3.14)(100)-50\\\\=78.5-50=28.5\ sq.u$

Hence, the correct answer is A 28.50 sq. u

Evelyn is making a candy that contains 25% dark chocolate and the rest milk chocolate. The candy has 3 pounds of milk chocolate.

Vitek1552 [10]

Part A:

Let c represent the total amount of chocolate there is in lbs.

c = 0.25c + 0.75c

Part B:

0.75c represents milk chocolate, and we know that there are 3 lbs of milk chocolate, so you can replace the 0.75c with 3 (representing 3 lbs):

c = 0.25c + 3

Divide all the terms by c:

1 = 0.25 + 3/c

Subtract 0.25 from both sides to combine the like terms:

0.75 = 3/c

Multiply all the terms by c to make the equation easier to work with:

0.75c = 3

Divide both sides by 0.75 to isolate the c and find the total amount of chocolate in pounds.

c = 4

Substitute c for 4 in the term that defines dark chocolate (which was 0.25c)

0.25(4) = 1 pound

Therefore, there was exactly 1 pound of dark chocolate present in the chocolate.

This makes sense, as 1 pound of dark chocolate + 3 pounds of milk chocolate = 4 pounds of chocolate in total, and 1 is 25% of 4 and 3 is 75% of 4.

Mrrafil [7]

Answer: x < 3

Step-by-step explanation:

Let's solve your inequality step-by-step.

7x−9<12

Step 1: Add 9 to both sides.

7x−9+9<12+9 =7x<21

Step 2: Divide both sides by 7.

7x/7 < 21/7

Answer: x < 3
