It is C.

First, you have to do the problem in the (), so 3*4 = (12). 12 - 2 is 10. Next, you do the other () which is 5 + 7 which is 12. 12 + 10 = 22

Can someone please help me solve for X i’m really confused and I really need help please

DochEvi [55]

Answer: x = 7

Step-by-step explanation:

sure thing! so, one angle is 34 degrees, and the other clear angle is 60 degrees. we know that because the angle on the lower shape matches that one. we then just add those, which comes out to 94 degrees. a triangle is 180 degrees, so we subtract 94 from that in order to figure out the total degrees in that last angle. that angle comes out to be 86 degrees. then, we subtract 2 in order to divide easily. we then divide 84 by 12, and we get 7. so, x = 7

Rosanne is training for the Austin marathon, so she plans to run 10 miles in her neighborhood this weekend. It usually takes her

PolarNik [594]

Answer:2.5 cups

Step-by-step explanation:

Given

Rosanne runs 6 miles in an hour

If she drinks 0.5 cups of water every $\frac{1}{3}$ of an hour

So in 1 hour Rosanne drinks 1.5 cups

So, for 6 miles Rosanne drinks 1.5 cups

i.e. For $1\ mile \quad \equiv \quad \frac{1}{4}\ \text{cup}$

for $10\ mile\quad \equiv \quad \frac{10}{4}\ \text{cup}$

$=2.5\ \text{cup}$

A 55m and 35m broad park is surrounded by a 2.5m wide path.

daser333 [38]

Step-by-step explanation:

☄ $\underline {\underline{ \text{Given}}} :$

Length of a park ( l ) = 55 m
Breadth of a park ( b ) = 35 m
Width running outside the park ( d ) = 2.5 m
Rate of paving the path with stones = Rs 120 per sq.metre

☄ $\underline{ \underline{ \text{To \: find}}}:$

Area of the park
Cosy of paving the path with stones at Rs 130 per sq.metre

☄ $\underline{ \underline{ \text{Solution}}} :$

Part 1 : $\boxed{\text{Area \:of \:a \:path \: running \:outside = 2d(l + b + 2d)}}$

plug the known values and simplify :

⟹ $\sf{2 \times 2.5(55 + 35 + 2 \times 2.5)}$

⟹ $\sf{5 \times 95}$

⟹ $\sf{475 \: {m}^{2} }$

Part 2 : $\boxed{ \sf{Total \: cost = Area \: of \: paths \: \times Rate}}$

⟹ $\sf{475 \times 120}$

⟹ $\sf{Rs \: 57000}$

$\purple{ \boxed{ \boxed{ \sf{ \tt{⟿ \: Our \: final \: answer : (i) = 475 \: {m}^{2} \: and \: (ii ) = Rs \: 57000}}}}}$

Hope I helped ! ♡

Have a wonderful day /night ツ
