HELP The Vertical Supports In This Truss Bridge Are Built So ThatAABO=AOCD. Which Of The Following Statementsis

Answers

Answer 1

Answer:

The statement that is not true is;

c) m∠ABO = m∠ODC

Step-by-step explanation:

With the assumption that the lengths AO, and OD are equal, we have that in ΔABO and ΔOCD, the following sides are corresponding sides;

Segment AO on ΔABO is a corresponding side to segment OD on ΔOCD

Vertices B and C on ΔABO and ΔOCD are corresponding vertices

Therefore;

Segments AB and OB on ΔABO are corresponding sides to segments OC and OD on ΔOCD respectively

Therefore, ∠ABO on ΔABO is the corresponding angle to ∠OCD on ΔOCD

Given that ΔABO ≅ ΔOCD, we have that ∠ABO ≅ ∠OCD

Therefore;

m∠ABO = m∠OCD by definition of congruency

2. Tadashi and his friend Abel make 18 dumplings. Tadashi eats one third, and Abel eats the rest. How many dumplings did Abel eat?​

Answers

Answer:

12

Step-by-step explanation:

18/3=6

so Tadashi ate 6 dumpling; the other 12 Able ate

Answer:

12

Step-by-step explanation:

Sine Tadashi eats one third, you have to divide the total amount of dumplings by three.

18/3=6

Tadashi eats 6 dumplings, so to find out how many Abel eats you have to subtract 6 from the total number of dumplings.

18-6=12

Abel ate 12 dumplings

The perimeter of a quadrilateral garden is 4x2+3x-4. The first side is represented by x2+2x+15. The second and third sides are each represented by x2-x-10. What expression represents the fourth side? Write a justification of your result.

Answers

Answer:

[tex]y = x^{2} + 3x + 1[/tex]

Step-by-step explanation:

Perimeter equals the sum of the lengths of the sides.

Let y = the length of the fourth side

[tex]4x^{2} + 3x - 4 = x^{2} + 2x + 15 + x^{2} -x - 10 + x^{2} - x - 10 + y[/tex]

[tex]4x^{2} + 3x - 4 = 3x^{2} - 5 + y[/tex]

[tex]x^{2} + 3x + 1 = y[/tex]

Find the sum
3 2/6 plus 1 3/6

Answers

Answer:

4 5/6

Step-by-step explanation:

3 2/6 plus 1 3/6

3 + 1 = 4

2/6 + 3/6 = 5/6

4 + 5/6 = 4 5/6

Answer:

4 5/6

Step-by-step explanation:

you start with the whole numbers, and 3+1 is 4 so we know that we need to add 4 to the sum of the fractions. next we need to add 2/6 and 3/6, to do that we just add the numeraters and we get 5 so it's 5/6. lastly we need to add the two numbers together and because we didn't get an improper fraction the answer is 4 5/6.

x=3 (change side change mark)

and

[tex] \frac{2}{3} x - 6 = 0[/tex]

[tex] \frac{2}{3} x = 6[/tex]

[tex]x = 6 \times \frac{3}{2} [/tex]

change side change mark.

So, x=9

If u wanna check the answer you can check by substitution x=3 and 9 in equation.

3) In June a gallon of gasoline cost $2.75. In July the price increased to
$2.92. What is the percent of increase of a gallon of gasoline from June to
July? Round to the nearest tenth.

Answers

Answer:

6.2%

Step-by-step explanation:

Hard to explain, but easy. Take your new value, and subtract your initial (starting) value from the new value. In this case, it would be 2.95-2.75= 17. You now can take you difference (17) and divide it by the initial value, so 17/2.75. This gives you 6.181818182. Round to 6.2%

You work at a frozen yogurt shop during the summer. You need to order 5-ounce and 8-ounce cups. The storage room will only hold 10 more boves. A box of 5 ounce cups cost $100 and a box of 8-ounce cups costs $150. A maximum of 1200 is budgeted for yogurt cups. Write a system of linear inequalities that shows the number of bonus of 5 ounce and 8 ounce cups that could be bought. Graph your result​

Answers

The way i did it: f+e =10

Value equation...:100f+150e=1250

Modify:100f+100e=1000

Substract the 1st from the 2nd to solve for e

50e=250

e=5 boxes

f+e=10 so f equals 5 boxes

find the length of the missing side Geometry

Answers

7.

Since it is a right triangle we can use Pythagorean Theorem to solve.

A^2+B^2=C^2

We are given C and B. We are solving for A, so we can input what we know.

A^2+24^2=25^2

A^2+576=625

A^2=49

A=7

Therefore, the missing side is equal to 7.

Write the equation of a line that goes through (4,3) and has a slope of m=2

Answers

Answer:

y = 2x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, then

y = 2x + c ← is the partial equation

To find c substitute (4, 3) into the partial equation

3 = 8 + c ⇒ c = 3 - 8 = - 5

y = 2x - 5 ← equation of line
