Osvoldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of
saw5 [17]

Answer:

Osvoldo did not meet his goal

Step-by-step explanation:

To know the percentage of carbohydrates that Osvoldo ate from grains with respect to the total, we simply have to divide the amount of carbohydrates he got with the grains by the total

55 / 220 = 0.25

then to express it as a percentage this number has to be multiplied by 100

0.25 * 100 = 25%

Osvoldo wanted to reach 30% and only got 25%

25% < 30%

Two cross roads ,each width 10m cut at right angle through the centre of a rectangular park of length 700m and breadth 300m and
Dafna11 [192]

Answer:

Step-by-step explanation:

Area of one  road = 700 x 10

7000 sq m

area of another road

= 300 x 10 = 3000sq m

Total area of road

= 7000 + 3000 - 10 x 10

= 9900 sq m

Area of park

= 700 x 300

= 210000 sq m

less area of road

= 210000 - 9900

= 200100 sq m

= 200100 / 10000 hectare

= 20.01 hectare.

In the diagram below, xy and yz are tangent to O. What is the measure of angle y
Tatiana [17]

If we draw in  OX, OY, OZ we have two congruent right triangles, right angles at the tangent points.

We know XOZ is 132 degrees, which is the meaning of the arc measure

So YOX is half that, 66 degrees.

That leaves 180 - 90 - 66 = 24 degrees for OYX

Angle Y aka XYZ is double that, 48 degrees.

Answer: C

Helpppppp meeeeee 3/4x - 9 = 27 two step equations helppppppp
In-s [12.5K]

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

First, add 9 to both sides

3/4x - 9 (+9) = 27 (+9)

3/4x = 36

Next, multiply 4/3 to both sides

(4/3)(3/4)x = 36(4/3)

x = 36(4/3)

Simplify.

x = 12(4)

x = 48

48 is your answer for x.

hope this helps
